Click here for a printable version of this file

SECTION I - CLASS DEFINITION

This class includes:

Apparatus or means relating to the type of amusement, recreational, or play activities commonly known as games or sports (a) in which one or more players or participants use a ball, missile, stream of water, or any other such body which occupies physical space and can be touched and thereby felt by the one or more players or participants (i.e., a tangible body) such that, during play of a game or sport, the ball, missile, or other such tangible body is thrown, rolled, shoved, impelled, propelled, projected, or otherwise put into motion by a nonexplosive force so as to achieve an objective set forth by rules defined for the particular game or sport and (b) wherein the result of playing such a game or sport can be indicated according to rules defined for the particular game or sport;

Devices which are ancillary or appurtenant to the types of games or sports included herein, unless they are provided for elsewhere.

(1) Note. The ball, missile, or other such tangible body is (a) usually initially put into motion by an external force supplied either by a player of the game or sport or by other nonexplosive means (e.g., by a mechanically operated device, etc.) and (b) usually continues in motion under its own inertia (in the absence of intervention or interception by another external force or by a body) after having been put into motion. However, a self-propelled ball, missile, or other such tangible body may be included herein provided it is intended to be used in the play of a game or sport.

(2) Note. In regard to devices or implements for striking, impelling, launching, or, otherwise, projecting a game projectile, the following applies: (a) Any projector device or implement which is combined with any other device, apparatus, or component used for a game or sporting purpose is included herein, (b) a striking type of projector implement which is used for a game or sporting purpose (such as a club, bat, racket, paddle, mallet, stick, etc.) and which is carried by (e.g., handheld) and manually manipulated by a user to strike and thereby project a game projectile such that substantially all of the force used to project the projectile is supplied by the user is, per se, included herein, (c) a throwing or flinging type of implement or device which is used for a game or sporting purpose and which is specifically adapted and intended to be used to both project a game projectile and to catch a game projectile after it has been projected (i.e., a combined projector-catcher device) is, per se, included herein, and (d) any projector device or implement (other than one which is operated by explosive means) which is used for a game or sporting purpose and which is specifically adapted and intended to project a game projectile so that it travels upon a playing surface substantially at all times (i.e., the projectile is in contact with and moving over the playing surface either upon or immediately after projection) is, per se, included herein. Centrifugally or mechanically operated device or implement, per se, for projecting a projectile into the air, which device or implement may be used to project a game projectile is located elsewhere. See References to Other Classes, below.

(3) Note. Although not generally used during the play of the types of games or sports included herein, devices or implements which are used by a player to practice or train for one of the types of games or sports included herein are provided for in Class 473. Since such practice and training devices or implements are designed to enable a player to improve or perfect his or her physical skills (e.g., motor skills, coordination, etc.) in the playing of any aspect of the game or sport for which it was designed for, they are included in Class 473 on the basis that they are ancillary or appurtenant to the types of games or sports provided for herein.

(4) Note. A ball, marble, die, top, etc. which is intended to be used as a chance device alone or intended to be used as part of a chance device or game apparatus (e.g., a die used as a chance device to generate a random number, letter, etc., a marble used as part of a roulette-wheel apparatus, or a die used to generate a number, letter, etc. during play of a board game apparatus, etc.) is not considered to be a projectile proper for Class 473 and is, therefore, excluded. Likewise, a marble or the like used to operate a "Rube Goldberg"" type of device, which device being used to play a game (for example, used in the play of a board game) is not considered to be a projectile proper for Class 473 and is, therefore, excluded. An object (often a representation of a horse, vehicle, person, etc.) which is propelled during play of a propelled racing game is not considered to be a projectile proper for Class 473 and is, therefore, excluded.

SECTION II - LINES WITH OTHER CLASSES AND WITHIN THIS CLASS

This class is specific under Class 463, Amusement Devices: Games, which, in turn, is specific under Class 472, Amusement Devices.

Class 273, Amusement Devices: Games, is currently being reclassified through a series of stages. Upon completion of this reclassification, Class 273 will be abolished and replaced either by Class 473 or by Class 463, Amusement Devices: Games. Until this reclassification is completed, the portions of Class 273 which are relevant to Class 473 are to be considered an integral part of Class 473. Specifically, subclasses 108+ and 317+ of the Class 273 schedule are to be considered as following in hierarchy after the last occurring subclass in the Class 473 schedule. The rest of the subclasses of the Class 273 schedule are, for the most part, to be considered as following in hierarchy after the last occurring subclass in the Class 463 schedule. Also, since Class 273 has not been completely screened for all patents properly classifiable in present subclasses of Class 473, appropriate subclass(es) in Class 273 should be considered for search purposes until such time that Class 273 is finally abolished.

LINE WITH CLASS 463

The relationship between Class 473 and Class 463 is that Class 463 is the residual class for games, while Class 473 provides only for those specific types of games in which a ball, missile, or other such tangible projectile (other than a simulation or representation thereof) is used during play thereof. Accordingly, if a game (or a game component thereof) which uses a ball, missile, or other such tangible game projectile (other than a simulation or representation thereof) during play thereof is claimed or solely disclosed, then classification is in Class 473, otherwise, classification is in Class 463 or in the appropriate subclasses of Class 273, Amusement Devices: Games, which follow behind the subclasses of Class 463. However, note that Class 463 provides for (a) a game apparatus or means which uses a simulation or representation of a tangible projectile (e.g., a light-ray simulation of a projectile, a computer generated representation of a projectile, etc.), (b) a propelled racing game in which an object (often a representation of a horse, vehicle, person, etc.) is propelled during play thereof, and (c) a chance device, either per se or in combination with a game which does not use a tangible projectile, whether or not a projectile is included therein, and even if it is not a game or subcombination element of a game (these are, for the most part, still located in Class 273). See also (4) Note above for further elaboration of exceptions to what is provided for in Class 473.

LINE WITH CLASS 345

See Class 463, Amusement Devices: Games, References to Other Classes, in the Search Class note to Class 345 for an elaboration of the line between Class 345 and Class 463, the parent class for Class 473. A selectively controlled visual display system combined with a game component of a game provided for in Class 473 (e.g., a golf club, golf ball, tennis court, tennis court net, etc.) or with a practice or training device therefor (e.g., a golf club swing training device, baseball bat swing training device, etc.) is proper for Class 473.

LINE WITH CLASS 434

Class 473 and subclasses 108+ and 317+ of Class 273, Amusement Devices: Games, contain devices which are to be used for practice by, or for perfecting the physical skill of, a person who already knows how to play the game, sport, or the like. Class 434 contains devices which are to be used for instructing an unknowledgeable person in some aspect of the game, sport, or the like. A device which is used both for instruction and for practice or perfection of game skills is originally placed into Class 434 and cross-referenced into the Class 463 group of game classes (i.e., Classes 463, 473, or 273).

LINE WITH CLASS 446

Class 446, Amusement Devices: Toys, for a device known as a toy whose principle purpose is for the amusement or recreation of a child. If the device is used for the amusement or recreation of a child and is also a game component (i.e., used in a competition or contest), then it is placed into the Class 463 group of game classes (i.e., Classes 463, 473, or 273).

SUBCLASSES

1	BILLIARDS OR POOL:
	This subclass is indented under the class definition.  Subject matter relating to a game which generally involves a horizontally disposed, planar playing surface bounded and defined by raised carom rails (i.e., bumper rails) for confining on the playing surface a plurality of balls which are being projected over the playing surface either into one another or rebounded off of the carom rails; the playing surface either (a) is continuous and has a continuous carom rail rim so that it is devoid of any pockets or other ball receiving receptacles (i.e., a billiard playing surface) or (b) has one or more pockets or receptacles adapted to receive therein or pass therethrough one or more of the balls (i.e., a pool or pocketed playing surface); in playing the game, at least one ball, commonly known as the cue ball, acts as a secondary projecting device and is used to strike and move over the playing surface one or more of the other balls, commonly known as object balls, which act as targets for the cue ball, the cue ball is first forcibly struck by a player aiming and manipulating a first projecting device, commonly known as a cue or cue stick, so as to project the cue ball either directly into engagement with the one or more of the object balls or by first banking or rebounding it off of one or more of the carom rails and then into engagement with the one or more of the object balls so as to move and either position the object balls in a specified arrangement on the playing surface or to pocket them, whereby the player may achieve a score according to the rules specified for the game. (1) Note. In a game of this type balls are usually used but it is to be understood that ball equivalents may be used in their stead provided that they act, other than the fact that they probably do not roll, in the same manner that balls would in playing the game. That is, the ball equivalents should move one another about over the playing surface and should carom or rebound off of one another or the carom rails in the same manner as balls would. (2) Note. Usually, the initial projecting device (i.e., the cue) used to strike the cue ball is a long, tapering, tipped rod or stick but other types of cues that may be used include a mechanically operated cue, a mallet type cue, etc. SEE OR SEARCH CLASS: 235,  Registers,   for a score totalizing apparatus, per se, intended for use in a game, particularly subclass 91 for a device for operating a register involving a billiards or pool game device.

2	Practice device or device to aid in aiming cue or cue ball during shots (e.g., to assist in bank shots, etc.):
	This subclass is indented under subclass 1.  Subject matter comprising either (a) a means to enable a player to improve or perfect his or her skills in the playing of any aspect of the game, or (b) a means to assist a player in determining the proper alignment or position that the cue device must be in so that the cue ball projected thereby moves in the desired direction, or (c) a means to assist a player in calculating or otherwise determining the direction or angle that the cue ball must be projected in order for it to, in turn, project the desired object ball or balls in the desired direction. SEE OR SEARCH THIS CLASS, SUBCLASS: 42+, for a device known as a cue rest or bridge. Although cue rests or bridges can somewhat be interpreted as assisting the player in aligning the cue during shots, they are not included here because their primary function is to aid in supporting the cue during difficult shots such as ones in which the player has difficulty in extending his or her cue supporting and guiding hand close enough to the cue ball to make a reasonably accurate shot. That is, cue rests or bridges do not primarily function to enable a player to determine the proper alignment or position of the cue or the proper direction or angle that a cue ball must be projected to achieve the desired result. SEE OR SEARCH CLASS: 434,  Education and Demonstration,   particularly subclasses 128+ for a means specifically adapted to teach or instruct a person in some aspect of playing a game which uses a gameboard or table such as chess or checkers, and subclasses 247+ for a means specifically adapted to teach or instruct a person in some aspect of a game or sport which involves physical activity.

	This subclass is indented under subclass 1.  Subject matter wherein, during play of the game, the playing surface is or is adapted to be located substantially on a surface that the player normally stands (e.g., on the floor, a rug, or the ground, etc.) or the playing surface comprises a court structure, either permanent or otherwise, which is located on such surface, whereby the player must use a mallet or club as the cue to strike the cue ball due to the playing surface being located at substantially his or her feet. (1) Note. Often the playing surface is of such size that the player stands on the playing surface during play of the game.

4	Table or gameboard:
	This subclass is indented under subclass 1.  Subject matter wherein the playing surface along with its peripheral carom rails are the upper surface portion of a furniture structure known as a table which is particularly adapted for playing the game of billiards or pool, whereby the playing surface is located generally at a height of somewhat the same level as the trunk region of the player"s body when the player is in standing position during play of the game; or wherein the playing surface along with its peripheral carom rails is a somewhat portable structure having no or very short legs or support structure, whereby the playing surface is adapted to be located on a support at approximately normal table height during play of the game. (1) Note. Also included herein, is a table or gameboard which presents its playing surface at, or adapted to be at, such a height that the player can play the game while in a sitting position. SEE OR SEARCH CLASS: 248,  Supports,   subclasses 188.2+ for an elevating or leveling device for furniture.

5	With mechanical ball projector:
	This subclass is indented under subclass 4.  Subject matter wherein the table or gameboard is combined with a mechanically operated cue means for projecting or impelling the cue ball over the playing surface. SEE OR SEARCH THIS CLASS, SUBCLASS: 45, for a mechanically operated cue device, per se, for projecting a ball over the playing surface of a billiard or pool game. SEE OR SEARCH CLASS: 273,  Amusement Devices: Games,   particularly subclasses 119+ for a surface projectile game device in which there is a mechanically operated means for projecting a ball over a playing surface, which projecting means is combined with and attached to the surface over which the ball is projected.

415	PLAYING FIELD OR COURT GAME; GAME ELEMENT OR ACCESSORY THEREFOR OTHER THAN PROJECTOR OR PROJECTILE, PER SE:
	This subclass is indented under the class definition.  Subject matter relating to a directly interactive and competitive game or sport in which two or more opposing players or teams of players located upon or within a playing area manipulate or otherwise use a game projectile during play of the game or sport, and over which playing area at least one of the two or more opposing players or teams, in trying to achieve the game objective, moves, either while manipulating the projectile or while interacting with, reacting to, or responding to another player who is manipulating the projectile or to movement of the projectile itself whenever it is free of the players" direct control, which game or sport includes any one of or a combination of the following: (a) a game component (e.g., a convertible goal or target device, etc.) which has a configuration that is adapted and intended to be changed so that it, in one configuration thereof, is a game component which is intended to be used in or for a game or sport included herein and, in another configuration thereof, is either a game component or a practice or training device that is intended to be used in or for a diverse type of game or sport which also uses a game projectile, which diverse type of game or sport is either a different game or sport included herein or a game or sport not included herein; (b) a kit of parts which is adapted and intended to be assembled or reassembled into a first game component intended to be used in or for a game or sport included herein and into either a second game component or a practice or training device which is intended to be used in or for a diverse type of game or sport which also uses a projectile, which diverse type of game or sport is either a different game or sport included herein or a game or sport not included herein; (c) a game component (other than a projector or projectile, per se) which is used during play of a game or sport included herein; or (d) an ancillary device or means (e.g., a cover for a playing field or court, etc.) which is adapted and intended to be used with or for a game component during the times that the game or sport is not being played (i.e., before or after the game or sport is played or during a time out) unless it is provided for elsewhere. (1) Note. A game or sport of the type to be included in this and the indented subclasses, must involve a game projectile, whether or not claimed. The projectile used by the two or more opposing players or teams of players may be manipulated in such a manner that it may be thrown, carried, struck, kicked, pushed, etc. by any portion of a player"s body or by a projector device carried by a player as dictated by the rules defined for the game. However, the projectile must, at some point in time during play of the game or sport, be free of the player"s direct control as, for example, when the projectile is thrown or otherwise projected either through the air or for movement over the playing area toward a goal or target or toward another player. (2) Note. The statement "directly interactive and competitive game or sport" referred to above is defined herein to mean that the opposing players or teams of players play the game or sport generally simultaneously (other than at such times as, for example, a penalty kick in a soccer game, etc.). Thus, for example, a game or sport in which a player, located upon or within a playing area, projects a projectile toward a goal or target and subsequently moves over the playing area to the location of the projected projectile for retrieval or reprojection thereof (as in the games of hopscotch, croquet, golf, horseshoes, etc.) is not considered to be a playing field or court game or sport as defined herein and is, therefore, excluded because the player is not moving over the playing area either while manipulating the projectile or while interacting with, reacting to, or responding to another player who is manipulating the projectile or to movement of the projectile itself. Further, most simple target games in which the players take turns in projecting or impelling a game projectile toward a goal or target in order to achieve a score higher that another player, although a competition in a broad sense, are excluded from these subclasses because the players are not directly interacting with another player at the same time during play of the game (i.e., there is no interference from an opposing player of the game) or because a player and his opponent are not both moving over the playing area at the same time during play of the game. (3) Note. A simple game of throw-and-catch in which the players may incidentally move over a playing area is not considered to be a playing field or court game or sport and is, therefore, excluded because the movement is caused by unintentional inaccuracy of the thrower in attempting to throw the projectile to the catcher. (4) Note. A game component which is used in a playing field or court game included herein, is defined as a device or means which is used during the times that the game or sport is being played. Although the following list is not to be considered as exhaustive, such a game component may include any of one of the following devices or means: (a) a playing area of indeterminate extent or a playing area defined by a visually (e.g., marked) or otherwise sensory distinct enclosing peripheral boundary or by an enclosure. However, this type of game component is, per se, excluded from these subclasses since it is classifiable elsewhere. That is, this type of game component, to be included here, must be combined with another game component which is included herein. See (6) Note below for a further discussion of this line. Such additional game component may be a court dividing net as in a tennis court, another interior playing field or court dividing means that breaks the playing area into compartments, sub-areas, or sections, as the ten yard line markings on a football field, a goal or target device, a game projectile, a projectile impelling device manipulated by a player, etc.; (b) a structure, per se (e.g., a net, barrier, etc.) or a visually or otherwise sensory distinct means, per se (e.g., a marked line, etc.) which is adapted and intended to break the playing area into compartments, subareas, or sections; (c) a goal or target, per se, for providing a point of aim for a game projectile projected thereat by a player; (d) a player-held and powered, nonmechanical implement adapted and intended to project a game projectile (e.g., a bat, tennis racket, polo mallet, hockey stick, etc.). However, this type of game component is, per se, excluded from these subclasses since it is classifiable elsewhere. That is, this type of game component, to be included here, must be combined with another game component which is included herein; (e) a game projectile (e.g., a ball, hockey puck, badminton shuttlecock, etc.). However, this type of game component is, per se, excluded from these subclasses since it is classifiable elsewhere. That is, this type of game component, to be included here, must be combined with another game component which is included herein; (f) a football kicking tee, per se, which is used once in a while during play of an American football game; (g) a means, per se, used by a player when projecting a game projectile for enhancing the movement of the projectile after projection thereof (e.g., a means that a player uses to assist in causing a pitched baseball to curve during flight); (h) a base, per se, adapted and intended to be located on or within a playing area used in a game involving base running (e.g., a base to be located at a corner of the diamond-shaped playing area used in playing the game of baseball, etc.); (i) a strike-zone detector (e.g., a detector for determining whether or not a ball pitched toward a batter located in the vicinity of home plate is within the strike zone in a baseball-type game, etc.) provided that it is claimed in combination with another game component classifiable herein (e.g., with the home plate, etc.); or (j) a boundary detector (e.g., a ball-out-of-bounds detector for use on a tennis court, etc.) provided that it is claimed in combination with another game component classifiable herein (e.g., with the tennis court, tennis court net, etc.). (5) Note. An accessory (i.e., an ancillary device or means) is generally not considered to be a game component unless it is convertible or is part of a kit of parts, as specified in parts (a) and (b) of the definition above. An accessory, per se, intended to be used with or for a game component used in a game or sport included herein, is often classified with the component it is intended to be used with or for, unless it is provided for elsewhere. For example, a press for a tennis racket is included under the subclasses providing for the tennis rackets which, in turn, is included under the subclasses providing for player-held and powered, nonmechanical projectors for projecting an aerial projectile into or through the air by striking. On the other hand, a cover, per se, for a playing field or court included herein is classified herein by itself near the end of the group of subclasses under this mainline subclass. Also, it should be kept in mind that some accessory devices or means are classifiable elsewhere as, for example, in other classes. (6) Note. The playing area itself, the peripheral boundary or enclosure itself, or both may be included in this and the indented subclasses provided that at least one other game component intended to be used in or for a playing field or court game or sport as defined above is also claimed in combination therewith. For example, a ball or a goal combined with a particular floor structure, a walled enclosure combined with a game racket, or a football field combined with a peripheral boundary marking and with an interior yard line marking would be included herein. However, a particular floor, field, or court structure per se, a particular walled enclosure per se, a peripheral boundary marking per se, or a particular floor, field, or court structure combined only with a particular walled enclosure or peripheral boundary marking would not be included herein. (7) Note. A means which is specifically adapted and intended to enable a player of a playing field or court game included herein to improve or perfect his or her physical skills (e.g., motor skills, coordination, etc.) in the playing of any aspect of the game or sport (i.e., a practice or training device) is included herein. SEE OR SEARCH THIS CLASS, SUBCLASS: 44+, for a projecting implement or apparatus used in playing the surface projectile game known as billiards or pool. 52+, for a ball used in playing a billiard or pool game. 107, for a mechanical projecting device used in playing the surface projectile game known as bowling. 125+, for a ball used in playing a bowling game. 219+, for a practice swingable implement used (by a player of the game known as golf) to improve or perfect his or her skill in playing the game. 280+, for a practice projectile used by a player of golf to improve or perfect his or her skill in playing the game. 282+, for a projecting implement used in playing a golf game. 351+, for a ball used in playing a golf game. 410+, for a projecting implement (e.g., a mallet, etc.) or a ball used in playing the surface projectile game known as croquet. 516+, for a player held and powered, nonmechanical, game projector, per se, which is used by a player to strike and thereby propel, impel, launch, or otherwise project a projectile into the air during play of a projectile game or sport. 569+, for a game projectile, per se, in general which is thrown, propelled, impelled, launched, or otherwise projected by a player during play of a projectile game or sport. SEE OR SEARCH CLASS: 52,  Static Structures (e.g., Buildings),   for an arena, stadium, or other building structure of general utility. 124,  Mechanical Guns and Projectors,   for a mechanically or centrifically operated projector device or implement, per se, which is used to project a projectile into or through the air as, for example, an archery bow, a slingshot, a baseball pitching machine, a tennis ball throwing machine, a clay pigeon throwing trap, or a fluid pressure, pinch, or centrifugally operated (e.g., a sling, etc.) type of projector device, etc. And see the (3) Note in the class definition of Class 473 above. 273,  Amusement Devices: Games,   for another game which also uses a tangible projectile, particularly subclasses 108+ for surface projectile game or apparatus therefor (other than a projectile, per se), subclasses 108.1+ for such a surface projectile game that mimics some aspect or the scoring of a playing field or court game such as the sports known as baseball, basketball, football, hockey, tennis, soccer, etc., subclass 129 for a projector used to project a projectile in such a surface projectile game, subclasses 317+ for an aerial projectile game or apparatus therefor (other than a projectile per se or a device or implement, per se, for projecting such a projectile), and subclasses 317.1+ for such an aerial projectile game that mimics some aspect or the scoring of a playing field or court game such as the sports noted above. Class 273 is currently undergoing reclassification and will eventually be replaced either by this Class 473 or Class 463, Amusement Devices: Games. Until this reclassification is completed, the subject matter of Class 273 relating to games or sports which use a tangible projectile is to be considered as following in hierarchy the last occurring subclass of the Class 473 schedule. Specifically, subclasses 108+ and 317+ of the Class 273 schedule are to be considered as following in hierarchy after the last occurring subclass in the Class 473 schedule. 463,  Amusement Devices: Games,   for a game apparatus or means, in general. The relationship between Class 473 and Class 463 is that Class 463 is the residual class for games, while Class 473 provides only for those specific types of games in which a ball, missile, or other such tangible projectile (other than a simulation or representation thereof) is used during play thereof. Accordingly, if a game (or a game component thereof) which uses a ball, missile, or other such tangible game projectile (other than a simulation or representation thereof) during play thereof is claimed or solely disclosed, then classification is in Class 473; otherwise, classification is in Class 463 or in the appropriate subclasses of Class 273, Amusement Devices: Games, which follow behind the subclasses of Class 463. However, note that Class 463 provides for (a) a game apparatus or means which uses a simulation or representation of a tangible projectile (e.g., a light-ray simulation of a projectile, a computer generated representation of a projectile, etc.), (b) a propelled racing game in which an object (often a representation of a horse, vehicle, person, etc.) is propelled during play thereof, and (c) a chance device, either per se or in combination with a game which does not use a tangible projectile, whether or not a projectile is included therein, and even if it is not a game or subcombination element of a game (these are, for the most part, still located in Class 273). 472,  Amusement Devices,   subclasses 92+ (a) for the structure or composition of a playing surface, per se (b) for the structure or composition of a peripheral boundary structure, marking, or enclosure per se, for such a playing surface, or (c) for the combination of only a playing surface and a peripheral boundary structure, marking, or enclosure; all of the above of which are limited to use for an athletic or exhibition event such as, for example, the playing of a game or sport thereon or therein. Also see the Search Notes appended thereto. 482,  Exercise Devices,   for a device adapted and intended to be used by a player of a playing field or court game for the sole purpose of strengthening or exercising his or her muscles so as to improve play of the game. If the device is adapted to be used along with a game component (as, for example, a weight to be attached to a baseball bat or a kicking exercise device intended for use with a soccer ball or football, etc.), then the device is classifiable in Class 473. Also, if the device is intended to be used either for exercising or for warmup by the player, then the device is classifiable in Class 473. 602,  Surgery: Splint, Brace, or Bandage,   for a device adapted and intended to be used for the treatment of a disorder or injury of a portion of the human body, particularly subclasses 5+ for an immobilization appliance (e.g., a splint, brace, etc.) for treating a disorder or injury of a body portion.

416	Having game element combined with or convertible to game element or practice or training device for different type of projectile game:
	This subclass is indented under subclass 415.  Subject matter comprising either (a) a game component which is used in playing a playing field or court game in accordance with a first set of rules combined on a common support or frame with another game component, or a portion thereof, of a different construction which is used to play or practice any other game or sport in accordance with a different set of rules or (b) a collection of components which are so constructed that at least some of the components may be and are specifically intended to be assembled, reassembled, or adjusted to form a game component which is used in playing a playing field or court game in accordance with a first set of rules and at least some of which collection of components are specifically intended to be assembled, reassembled, or adjusted to also or alternatively form another game component, or a portion thereof, which is used to play or practice any other game or sport in accordance with a different set of rules (e.g., a collection of components which can be assembled to form a soccer goal and reassembled to form a football goal). (1) Note. The second game component, with which the game component used in a playing field or court game is combined or which may be alternatively formed from the collection of components used to form the game component used in a playing field or court game, need not necessarily be used in a playing field or court game (e.g., a basketball goal which is combined with a dart board).

417	Means removably supporting projectile in position to be struck and thereby projected by player (e.g., batting tee, etc.):
	This subclass is indented under subclass 415.  Subject matter comprising a structure adapted to support a game projectile relative to the ground so that it may readily be struck and thereby impelled by a player of a playing field or court game or by a player practicing or training for such a game, which supporting structure is in the form of (a) a means having an underlying projectile receiving seat upon which the projectile is intended to removably rest, (b) an overhead member having means for removably suspending the projectile therefrom, or (c) an overhead member for engaging the top of the projectile so that the projectile is removably held between the overhead member and either the ground or an underlying member or mechanism upon which the projectile removably rests or by which the projectile is removably held. (1) Note. The support structure may be an upwardly extending column or stream of fluid, the seat being formed when and where the fluid impinges upon or interacts with the projectile. (2) Note. The term "removably" as it is used above means that the projectile (a) is merely freely resting upon the support structure, (b) is releasably attached to the support structure (e.g., by means of a tether releasably supporting a projectile in suspended position, etc.), or (c) is releasably held by the support structure (e.g., held between an overlying member and the ground or an underlying member or mechanism, etc.).

418	Projectile suspended or is supported by column of fluid:
	This subclass is indented under subclass 417.  Projectile supporting structure in the form of either (a) an overhead member having means for removably suspending the projectile therefrom or (b) an upwardly extending column or stream of fluid, the seat being formed when and where the fluid impinges upon or interacts with the projectile. (1) Note. If the projectile supporting structure provides both an underlying seat upon which the projectile rests and an overhead means for also supporting a projectile from above as, for example, for supporting a tip of a football in an upwardly facing direction, then the projectile is not considered to be suspended and is, therefore, excluded from this subclass. That is, a projectile that is supported in a suspended fashion is considered to have no underlying means of support.

419	Having means engaging top of projectile (e.g., kicking trainer or tee, etc.):
	This subclass is indented under subclass 417.  Projectile supporting means in which the projectile supporting structure is in the form of an overhead member for engaging the top of the projectile so that the projectile is removably held between the overhead member and either the ground or an underlying member or mechanism upon which the projectile removably rests or by which the projectile is removably held.

420	For projectile intended to be projected by kicking (e.g., kicking trainer or tee, etc.):
	This subclass is indented under subclass 417.  Projectile supporting means which is specifically adapted and intended to support a projectile or its equivalent in such a manner as to enable a user of the means to strike the projectile or its equivalent with at least one of his or her feet. (1) Note. The projectile supporting means may be used for the purpose of supporting a projectile in a kicking position during play of a playing field or court game as, for example, for the kicking of extra points or field goals in an American football game or it may be used for the purpose of enabling a player of a playing field or court game to improve or perfect the action of kicking a projectile (i.e., a practice or training device).

421	Batting backstop or cage:
	This subclass is indented under subclass 415.  Subject matter either (a) comprising a walled or screened partial enclosure intended to be positioned generally behind, beside, or above a baseball batter in order to limit or intercept the travel of a projectile which has been pitched or hit to the rear, sides, or above the batter for protecting persons or things outside the area bounded by the partial enclosure, the partial enclosure being open in at least an area generally in front of the batter or (b) comprising a walled or screened full enclosure which does not bound or enclose a playing field or court and within which a batter stands while practicing batting a projectile.

422	Practice or training device:
	This subclass is indented under subclass 415.  Subject matter comprising a means specifically adapted and intended to enable a player of a playing field or court game to improve or perfect his or her physical skills (e.g., motor skills, coordination, etc.) in the playing of any aspect of the game or sport. (1) Note. Even though goals, targets, projectors, projectiles, or other game elements, per se, which are normally used during the play of a playing field or court game or sport could also be used for practice or training, they are classifiable in appropriate subclasses other than this group of subclasses (i.e., 422+) unless a feature intended to enhance their practice or training function is specifically claimed or solely disclosed. SEE OR SEARCH THIS CLASS, SUBCLASS: 207+, for a practice device, used by a person to practice for an aspect of the game of golf, attachable to the body of a person. 219+, for a practice swingable implement or indicator associated with a swingable implement, which implement or indicator being used by a person to practice for an aspect of the game of golf. 278+, for a practice projectile-addressing surface used by a person to practice for an aspect of the game of golf. 280+, for a practice projectile used by a person to practice for an aspect of the game of golf. 416, for a playing field or court game having a game component combined with or convertible to a game component or a practice or training device for a different type of projectile game or sport.

423	Tethered projectile:
	This subclass is indented under subclass 422.  Practice or training device comprising a projectile or a tangible means simulating a projectile which is adapted and intended to enable a practicing or training player to improve or perfect (a) the action of propelling, throwing, rolling, impelling, sliding, pushing, or otherwise projecting a game projectile, (b) the action of catching a game projectile, or (c) the action of grasping and pulling a game projectile; which projectile or tangible means simulating a projectile is attached or has means intended to be attached to an elongated means which, in turn, is secured or is intended to be secured to an anchoring means (such as a support, etc.) or to a body portion of the player, whereby the projectile or tangible means simulating a projectile is constrained for movement within the extent of the elongated means whenever it is propelled, projected, etc., caught, or grasped and pulled by the player. SEE OR SEARCH THIS CLASS, SUBCLASS: 138, for golf game apparatus comprising a projectile tethered to a swingable implement. 139+, for golf game apparatus comprising an anchored (e.g., tethered, etc.) projectile. 575+, for a projectile having an attached or a means for attaching thereto a tether, elongated flaccid streamer, or the like, which projectile is intended to be used for playing a game which uses a game projectile but not intended to be used for practice or training purposes.

424	Tether attached to means adapted to be held by, carried by, or attached to person:
	This subclass is indented under subclass 423.  Tethered projectile wherein the elongated means is secured to an element intended to be held by, carried by, or secured (e.g., worn, etc.) to either a person using the practicing or training device or a person assisting the person using the practice or training device. (1) Note. The person held, carried, or attached element may be formed in or by a portion of the elongated means itself, such as a portion of the elongated means formed into a knot or loop which is intended to be gripped by the hand or attached to the wrist of the person, provided that it is expressly disclosed that the elongated means is intended to be held by, carried by, or attached to the person manipulating the device.

425	Person held, carried, or attached means is nonmechanical projector:
	This subclass is indented under subclass 424.  Tethered projectile device wherein the person held, carried, or attached element is a manually manipulated implement for striking, impelling, or otherwise projecting a projectile and wherein substantially all of the force used to strike, impel, or otherwise project the projectile is supplied by the person.

426	Projectile tethered between opposed tether sections:
	This subclass is indented under subclass 423.  Tethered projectile device wherein the elongated means includes at least two portions extending in generally opposite directions from the projectile, a distal part of each portion being, or intended to be, attached to an anchoring means, and a proximal part of each portion being fixed to, at, or about the projectile.

427	Projectile continuously driven in closed orbit prior to being struck:
	This subclass is indented under subclass 423.  Tethered projectile device comprising a motive means for constantly moving the projectile along a closed path prior to the impact imparted thereupon by the practicing or training player. (1) Note. The motive means may be power-operated (e.g., by an electric motor, etc.) or hand-operated (e.g., by a hand crank, etc.).

428	Projectile slidable along a line:
	This subclass is indented under subclass 423.  Tethered projectile device wherein the projectile is mounted to the elongated member by means allowing it to shift position along the length of the elongated member. (1) Note. A device in which the elongated member itself is comprised of two or more relatively sliding sections will be found in subclass 423 above unless the projectile itself is also slidable relative to at least one of the sections.

429	Tether pivotally attached for orbital revolution:
	This subclass is indented under subclass 423.  Tethered projectile device wherein a portion of the elongated means, remote from the point of its attachment to the projectile, is secured to the anchor means by a pivotal connection which permits the tether and the projectile to orbitally revolve about the anchor means (or at least about the connection to the anchor means) similar to the manner in which the earth orbitally revolves about the sun. (1) Note. If the tether is of the type comprising a flaccid cord, rope, etc. from which the projectile is suspended and the connection to the anchor means is by means of swivel which permits the tether to rotate only about its own axis similar to the manner in which the earth rotates about its own axis, then this type of tether is excluded from this subclass. (2) Note. If the tether is of the type comprising a flaccid cord, rope, etc. from which the projectile is suspended, then the portion of the tether which is secured to the anchor means must itself be capable of rotating about an axis (e.g., by means of a rotatable collar, ring, swivel, eyelet, etc. or by means of a loosely fitting looped portion thereof). A flaccid cord, rope, etc., which is tightly tied or knotted to a portion of the anchor means is not considered to be a pivotal connection proper for this subclass as indicated in the Search note below. SEE OR SEARCH THIS CLASS, SUBCLASS: 430, for a tethered-projectile type of practice or training device in which the projectile is suspended by the tether but in which the connection to the anchor means is not by means of a pivotal connection.

430	Projectile suspended by tether:
	This subclass is indented under subclass 423.  Tethered projectile device wherein the projectile is hung from the anchoring means by the elongated means. SEE OR SEARCH THIS CLASS, SUBCLASS: 418, for a teeing means removably supporting a projectile in position to be struck and thereby projected by a player, which teeing means being of the type for removably suspending the projectile therefrom and which teeing means may either be intended to be used to play a game (e.g., for a teeball game, etc.) or be intended to enable a player to practice or train for play of a game (e.g., a batting practice device, etc.). 429, for a tethered projectile device used by a player to practice or train for play of a game, which device may be of the type for suspending the projectile therefrom but in which the tether is pivotally secured to the anchor means to permit the tether and the projectile orbitally revolve about the anchor means or a portion thereof.

431	Having projectile return means:
	This subclass is indented under subclass 422.  Practice or training device having a means to cause a projectile which has been projected, struck, slid, propelled, thrown, etc. by and away from a practicing or training player to be moved back to a point located in the general vicinity of the player for the purpose of providing more ready retrieval of the projectile by the player.

432	Return chute:
	This subclass is indented under subclass 431.  Practice or training device wherein the projectile return means comprises an inclined or otherwise vertically oriented trough, passage, or the like down which the projectile moves due to the influence of a gravitational force acting thereon. (1) Note. The inclined or otherwise vertically oriented trough, passage, or the like must function to direct the projectile back toward the practicing or training player.

	This subclass is indented under subclass 415.  Subject matter comprising means adapted and intended to break the playing area into two or more compartments, subareas, or sections or comprising a component part thereof or an ancillary means therefor unless elsewhere provided for. (1) Note. The field- or court-dividing means may comprise a net, fence, wall, rope, chain, curtain, or a line or zone marking located on or otherwise located within the confines of the playing area or located in the vicinity of the boundary of the playing area. (2) Note. Although the field- or court-dividing means is usually located within the confines of the playing area, it may also comprise means located at or in the vicinity of the outer boundary marking structure or enclosure. However, this type of dividing means must still function to at least help break the playing area into two or more compartments, subareas, or sections. An example of this type of field or court dividing means might be one or more markers spaced along the length of a field or court for assisting in defining real or imaginary lines across the width of the playing area of the field or court. For example, the numerical yardline markers which are spaced every ten yards along the length of the playing field used in the play of an American football game, in conjunction with the lines marked across the width of the field, function to assist in the location of the ball or a player on the field.

505	PLAYER HELD DEVICE FOR BOTH PROJECTING AND CATCHING AERIAL PROJECTILE; PART THEREOF OR ACCESSORY THEREFOR (I.E., COMBINED PROJECTOR-CATCHER DEVICE):
	This subclass is indented under the class definition.  Subject matter (a) comprising a handheld or body-mounted implement for throwing, impelling, launching, or otherwise projecting a projectile into or through the air and wherein the implement is either (1) also used to capture or trap a projectile already moving through the air, or (2) includes an additional means to capture or trap a projectile already moving through the air; (b) comprising a constituent part of such an implement; or (c) comprising an ancillary means adapted and intended to be used with or for such implement not elsewhere provided for. (1) Note. The terms "catch," "capture," and "trap" as used herein mean that the primary function of the projector-catcher implement is to be so manipulated by the user to stop or intercept a game projectile during its flight through the air and that the implement carries and holds the intercepted projectile therein or thereon so that it may again be thrown, impelled, launched, or otherwise projected into the air from the implement upon manipulation thereof by the user. However, the implement may include means so that it may, at times, be also used to scoop a projectile off the ground so as to project it into the air provided that the implement also has means to carry or hold the projectile therein or thereon prior to projection thereof. (2) Note. A "catcher" as defined herein is distinguished from a ""target" in that a catcher is manipulated by the user in an effort to catch or intercept and trap the projectile while a target is merely an aiming point for a projectile projected thereat. Any movement of a target is intended to make the target more difficult to be struck by a projectile aimed and projected thereat. (3) Note. The term "catching" embraces catchers in the form of pocket-type receptacles (with or without outlet passages), open-bottomed pockets which trap and retain a projectile therein (i.e., apertured catchers which have apertures smaller than the projectile), and rodlike or hooked appendages. (4) Note. These combined projector-catcher implements may be used in a number of ways. For example, an impaling type of projector-catcher implement consisting merely of a rodlike member having a gripping portion may be used by (a) a user to launch a projectile removably impaled upon the rodlike member into the air and subsequently manipulated to catch (i.e., impale) the launched projectile upon the same rodlike member, (b) a user having two such rodlike members, one in each hand, and the projectile is launched by the user from the rodlike member in one hand to be caught by the rodlike member in the other hand, or (c) two or more users therefor, each having one such rodlike member and the projectile is launched into the air from the rodlike member held by one user to be caught by (i.e., impaled upon) the rodlike member held by another user. SEE OR SEARCH THIS CLASS, SUBCLASS: 503, for a means, other than an article of apparel (e.g., a baseball glove, etc.), adapted to be held or carried by a player of a playing field or court game for the sole purpose of catching a game projectile during play of the game. SEE OR SEARCH CLASS: 124,  Mechanical Guns and Projectors,   subclass 5 for a projecting implement, per se (e.g., a sling, etc.) which is held in the hand of a person and caused to throw a missile into or through the air by a centrifugal or swinging movement of the person"s arm. 273,  Amusement Devices: Games,   subclass 412 for a user manipulated device, other than an article of apparel (e.g., a baseball glove, etc.), which is used solely for the purpose of catching a game projectile moving through the air.

506	With tethered projectile:
	This subclass is indented under subclass 505.  Subject matter wherein the projector-catcher implement has one end of an elongated member attached thereto which, in turn, has an aerial projectile attached to the other end thereof so that the projectile is constrained for movement within the extent of the elongated member whenever it is thrown, impelled, launched, or otherwise projected into the air from the implement. SEE OR SEARCH CLASS: 273,  Amusement Devices: Games,   subclass 329 for a handheld manipulating implement having an aerial projectile tethered thereto and having an aperture formed therein so that the projectile is intended to be passed entirely through the aperture upon manipulation of the implement and subclass 330 for a handheld manipulating implement having an aerial projectile tethered thereto, which implement is intended to merely strike the projectile so as to project it into the air or the implement is intended to be struck by the aerially moving projectile upon manipulation of the implement. The latter implements are usually a paddle member having a handle extending therefrom and having a resilient projectile tethered thereto.

507	Having pocketed catcher:
	This subclass is indented under subclass 506.  Subject matter wherein the catcher part of the implement is either (a) in the form of a closed-bottom receptacle which is intended to stop and retain the projectile therein, or (b) in the form of a through aperture which is somewhat smaller in dimension than the projectile so as to stop, trap, and retain the projectile therein.

508	Having elastic tether:
	This subclass is indented under subclass 507.  Subject matter wherein the tether is a resilient flexible member or is secured to a resilient means (e.g., a spring-powered rewinding mechanism, etc.) attached to the implement.

509	Having projectile conducting means between separate entrance and exit (e.g., continuous orbit, etc.):
	This subclass is indented under subclass 505.  Subject matter wherein the projector part and the catcher part of the implement are spaced apart from one another but are interconnected by a passageway, conduit, trackway, or surface formed in the implement for conducting the projectile, when caught, from the catcher part to the projector part while remaining with the implement.

510	Both projector and catcher are pocketed:
	This subclass is indented under subclass 505.  Subject matter wherein either (a) the projector part is also used as the catcher part and is in the form of either a closed-bottom receptacle or an apertured receptacle, the aperture of the apertured receptacle having a dimension somewhat smaller than the projectile, whereby the receptacle, in performing its catching function, is intended to stop, trap, and retain the projectile therein, or (b) the projector part and the catcher part are separate portions of the implement and are both in the form of a closed-bottom receptacle, an apertured receptacle, or a combination of both a closed-bottom receptacle and an apertured receptacle, the aperture of the apertured receptacle having a dimension somewhat smaller than the projectile, whereby the catcher part of the implement, in performing its catching function, is intended to stop, trap, and retain the projectile therein.

511	With mechanical projection:
	This subclass is indented under subclass 510.  Subject matter wherein the projector part comprises or includes a mechanically operated means associated with the receptacle for achieving or assisting the impelling or launching of a projectile into the air. (1) Note. Also included in this subclass are projector-catcher implements formed from a flexible sheet means which is flexed by the user to achieve or assist the propelling or launching of a projectile resting on the sheet means. The flexible sheet means either has a closed-bottom receptacle formed therein or located thereon so as to form a closed-bottom receptacle. The flexing of the sheet means by the user (e.g., the pulling upon the ends of the sheet means so as to tension or stretch it) causes a projectile resting thereon to be propelled or launched into the air and, therefore, constitutes a mechanically operated means to propel or launch a projectile.

512	Pocket-to-pocket type:
	This subclass is indented under subclass 510.  Subject matter wherein the receptacle of the projector part and the receptacle of the catcher part are separate portions of the implement so that the projectile is launched into the air from the projector-part receptacle and caught by the catcher-part receptacle. (1) Note. The catcher part of the implement may comprise plural receptacles.

513	Having pocket with laterally facing opening (e.g., lacrosse stick, jai alai cesta, etc.):
	This subclass is indented under subclass 510.  Subject matter wherein the projector part and the catcher part are combined into a single closed-bottom receptacle which is used both to catch a projectile moving through the air and to propel or launch the projectile back into the air and wherein the implement includes an elongated handle member attached to and extending outwardly from the closed bottom receptacle such that the open portion of the receptacle faces in a direction generally perpendicular to the longitudinal axis of the handle member, whereby the implement as a whole has a general configuration somewhat similar to a spoon-shaped utensil. (1) Note. The closed-bottom receptacle which constitutes both the projector and catcher parts of the implement may be quite large relative to the projectile and this receptacle may itself have a secondary closed-bottom receptacle formed therein for holding and retaining a projectile at rest therein. Many lacrosse sticks are exemplary of this type of implement. When the implement is manipulated to project a projectile, a projectile resting in the secondary receptacle is moved out into the main receptacle and projected therefrom, mainly by centrifugal forces. When the implement is manipulated to catch a projectile moving through the air, the implement is manipulated so that the bottom of the main receptacle intercepts (thereby stopping) the flight of the projectile, whereupon the projectile drops by gravity into the secondary holding receptacle so that it may again be projected. SEE OR SEARCH CLASS: 124,  Mechanical Guns and Projectors,   subclass 5 for a projecting implement, per se (e.g., a sling, etc.), which is held in the hand of a person and caused to throw a missile into or through the air by a centrifugal or swinging movement of the person"s arm.

514	Having impaling, hooking, or ensnaring type catcher:
	This subclass is indented under subclass 505.  Subject matter wherein the projector-catcher implement comprises or includes a protrusion, rod, bar, ring, hook, or the like means for removably receiving thereupon an aerially moving projectile having cooperating complementary means (e.g., the projectile having an aperture therein for mating with the protrusion, comprising or having a hook member for being caught upon the bar, rod, hook, or ring, or comprising two parts interconnected by a flexible member or tether so that it may drape itself over the bar or rod, etc.) adapting it to be impaled upon the protrusion or hooked upon, draped over, or otherwise ensnared by the rod, bar, ring, hook, or the like means upon manipulation of the implement by the user; and wherein the protrusion, rod, bar, ring, hook, or the like means is so configured and adapted to enable the impaled, hooked, draped, or otherwise ensnared projectile to be reprojected back into the air upon manipulation of the implement by the user.

515	Having pocketed catcher connected to but spaced apart from projector:
	This subclass is indented under subclass 505.  Subject matter wherein the projector part and the catcher part are disposed at different locations upon the implement and wherein the catcher part is either (a) in the form of a closed-bottom receptacle which is intended to stop and retain the projectile therein or (b) in the form of an apertured receptacle comprising a through-aperture dimensioned somewhat smaller than the projectile so that the projectile is intended to be stopped and retained within the aperture of the receptacle.

516	PLAYER HELD AND POWERED, NONMECHANICAL PROJECTOR, PER SE, FOR PROJECTING AERIAL PROJECTILE BY STRIKING; PART THEREOF OR ACCESSORY THEREFOR:
	This subclass is indented under the class definition.  Subject matter (a) comprising an implement, per se, which is held and used by, or worn on the body of and used by, a player during play of a game or sport in which a game projectile is intended to move through the air during play of such game or sport, which implement is intended to enable the player to impart an impact upon the projectile so as to thereby propel, impel, launch or otherwise project the projectile into the air, through the air, or already moving through the air such that substantially all of the force used to impact the projectile is supplied by the player; (b) comprising a constituent part of such a player held or worn impact implement; or (c) comprising an ancillary means adapted and intended to be used with or for such player held or worn impact implement not elsewhere provided for.
