In some harvesters one axis is common to one roller of a snapping unit and one roller of a husking unit, and another parallel axis is common to the other roller of said snapping unit and the other roller of said husking unit. However, each unit functions without regard to the other, therefore the structure is proper for this subclass.

CARRIERS:

This subclass is indented under the class definition. Devices comprising a storage type receiver mounted on a harvesting machine or partially supported at the side of such machine by a mobile support in proper position for receiving harvested crop from the harvester as it travels over the ground.

(1) Note. This subclass is directed primarily to a specific subcombination of a harvesting machine and should include the harvester by name only. Patents claiming structural features of the harvester are classified on the basis of such structural features.

Land Vehicles, subclasses 400+ for articulated vehicles in which a drawn vehicle may track at the side or rear of a drawing vehicle. Trailing vehicles in the vehicle subclasses are, for the most part, adaptable for use with any drawing vehicle, and are not designed for use with a specific type machine. See particularly subclasses 411.1+ for multiple tractor-towed vehicles which by disclosure may be a harvester and receiver or wagon.

414,

Material or Article Handling, subclasses 334+ for a moving, wheeled, load-transporting type vehicle and a loading or unloading device therefor, which device is supported at least in part independently of the vehicle and travels with the vehicle during the transfer of a load from the device to the vehicle or vice versa.

SHEAF OR BUNDLE DISCHARGING CARRIERS:

This subclass is indented under the class definition. Devices comprising means attached to a binder or baler traveling over a field for receiving a sheaf, bundle or bale from said binder or baler and handling the sheaf, bundle or bale to deposit it on the field.

(1) Note. A single sheaf, bundle or bale may be deposited on the field at one time or a group of sheaves, bundles or bales may be collected for depositing on the field at the same time.

(2) Note. The handling device attached to the binder or baler may be of a trailing vehicle type.

(3) Note. This subclass comprises an art collection. The binder or baler should be claimed by name only or without any detail of the binding or baling mechanism.

193,	Conveyors, Chutes, Skids, Guides, and Ways, appropriate subclasses, especially subclasses 4+ for sheaf, bundle or bale depositing devices comprising no more than a mere trough chute or guideway for depositing sheaves, bundles or bales on the ground.
198,	Conveyors: Power-Driven, for power-driven devices for moving sheaves, bales or bundles along a path; see subclasses 717+ for a conveyor having means for changing the attitude of the conveyed load relative to the conveying direction.
414,	Material or Article Handling, subclass 789.7 for discharging from a vehicle-carried bale accumulator, subclass 111 for a vehicle-carried bale accumulator, and subclasses 334+ as explained in subclass 473.5 for this class (56).

475	Automatic discharge:
	This subclass is indented under subclass 474. Devices having means to trip automatically the mechanism for discharging the sheaf, bundle or bale.

476	Directly tilting:
	This subclass is indented under subclass 475. Devices wherein the carrier swings about a fixed horizontal axis to discharge the sheaf, bundle or bale.

477	Endless carrier:
	This subclass is indented under subclass 474. Devices wherein the sheaf, bundle or bale rests on an endless carrier which is normally motionless, but may be thrown into gear to discharge the sheaf, bundle or bale.

478	Folding tines:
	This subclass is indented under subclass 474. Devices having a series of tines which normally project transversely to the line of travel, but may be folded about approximately vertical axes to discharge the sheaf, bundle or bale.

479	Opening bottom:
	This subclass is indented under subclass 474. Devices having a receptacle with a bottom which is opened to discharge the sheaf, bundle or bale.

480	Directly tilting:
	This subclass is indented under subclass 474. Device wherein the carrier swings about a fixed horizontal axis to discharge the sheaf, bundle or bale.

STALK CHOPPERS:

This subclass is indented under the class definition. Devices in which a means is provided for cutting dead crop material into a plurality of small pieces.

(1) Note. This definition includes devices for chopping up leaves, brush, plant stalks and stubble. While the stalks are generally broken down or already severed from their roots and lying on the ground, they may be stalks which are still standing but from which the ears or the like have been picked.

172,

Earth Working, especially subclasses 35+ and 518+ for stalk choppers which chop the stalks into small pieces by shearing the same between a cutting member and the earth"s surface. Generally the cutting member is a blade on a drum which rolls or is driven along the ground in such fashion that the ground acts as a back up means against which the cutter member bears as it shears through the stalks, the ground surface being at the same time either intentionally or merely incidentally stirred or agitated.

501	Gathering by air current:
	This subclass is indented under subclass 500. Devices in which there are means for causing a current of air to gather or feed crop material to the means for cutting the same into a plurality of small pieces.

With driven pickup:

This subclass is indented under subclass 500. Devices in which a separate gatherer is provided for picking up the crop material which is to be cut into a plurality of small pieces by the crop cutting means and said gatherer is driven so as to have a regular cyclical motion with respect to its mounting frame.

1,	for devices for picking up hay and chopping the same into small pieces for subsequent delivery to a truck, storage bin or like receptacle.

503	Rotating on vertical axis:
	This subclass is indented under subclass 500. Devices in which the crop cutting means rotates about an axis which is perpendicularly disposed relative to the ground.

This subclass is indented under subclass 500. Devices in which the crop cutting means rotates about an axis which is perpendicular to the line of draft and which lies in a plane which is parallel to the ground.

SEE OR SEARCH THIS CLASS, SUBCLASS:

501,	and 502, for the combination of air current or driven stalk gathering or pick up means with stalk chopping means, which latter means is generally disposed to rotate about a horizontal transverse axis.
505,	Devices under subclass 504 in which a fixed, elongated, transversely disposed blade or plate is so associated with the rotary crop cutting means that during rotation of the latter the crop material will be sheared off between the blade or plate and a cooperating shearing surface or element of the rotary cutting means.
