Click here for a printable version of this file

SECTION I - CLASS DEFINITION

This class comprises all devices combined with handles, terminal elements, or attachments peculiarly adapted for engaging supporting articles or materials for handling or manipulating purposes and not structurally limited to any classified art and such combinations thereof and accessories therefor as not elsewhere classifiable.

(1) Note. This class includes power applying element which relate to the engaging of the load and not to its movement thereafter, except that a means for applying a straight line force or push to the load after the load has been released from the engaging means to move the load away from the engaging means is classified in this class.

(2) Note. The addition of wheels to any type of handlers included in this class, except where such addition is merely incidental, (such as adding casters to hoisting buckets), is held to involve transportation combinations.

SECTION II - LINES WITH OTHER CLASSES AND WITHIN THIS CLASS

(1) Note. This class does not include hoisting machines, which are provided for in Class 414, Material or Article Handling.

(2) Note. For hand and hoist-line terminal implements and attachments, classifiable on their necessary function in more elemental classes, see particularly, Classes 24, Buckles, Buttons, Clasps, etc., 279, Chucks or Sockets, and 403, Joints and Connections.

(3) Note. For hand and hoist-line terminal implements and attachments so specialized as to be of only limited application as handling devices see particularly lasses 30, Cutlery, 43, Fishing, Trapping, and Vermin Destroying, 56, Harvesters, 81, Tools, 111, Planting, 119, Animal Husbandry and 258, Railway Mail Delivery.

(4) Note. For hand and hoist-line terminal implements and attachments involving features additional to mere handling, such as changing the shape or condition of the matter engaged, see particularly Classes 37, Excavating, and 100, Presses.

(5) Note. For power applying elements that relate to the movement of the load see Classes 198, Conveyors: Power-Driven, 212, Traversing Hoists, 414, Material or Article Handling, 254, Implements or Apparatus for Applying Pushing or Pulling Force, and 280, Land Vehicles.
