DEFINITION

Classification: 414/509

Comprising load-engaging element reciprocably movable parallel to generally horizontal load-supporting component of vehicle for ejecting load therefrom:

(under subclass 507) Apparatus wherein the conveyor comprises a load-engaging element (e.g., a pusher plate), which is caused to move back and forth in a direction, which is approximately parallel to a load-supporting component of a vehicle (e.g., the floor of a truck body), which component has a generally horizontal attitude, for the purpose of removing a load from the portion.

(1) Note. While the claims of the art in this and the indented subclasses may not always bring out clearly the actual departure of the load from the vehicle, the disclosure should leave no doubt that the intent is to discharge, not merely reposition, the load.

SEE OR SEARCH THIS CLASS, SUBCLASS:

258+, for apparatus for charging or discharging a facility comprising one or more sites for the parking of wheeled vehicles, which apparatus includes a means for exerting a generally horizontal force for transferring a vehicle to or from a carrier from or to a site.

280, for plural, static structures for supporting discrete loads and a charging or discharging means therefor, and wherein the structures comprise load-underlying members, and the means includes a load sustaining surface and a push-pull mechanism to transfer a load, with a horizontal component of movement, from one of the members to the surface or vice versa.

374, for the concept of unloading a moving vehicle by utilizing the momentum of the load.

390+, for a driven external means for unloading a wheeled, load-transporting type vehicle, especially subclass 393 for removing a load by means of a flexible, load-underlying member which raises the load and moves it laterally.

395+, for removing a load by a pushing or pulling means. 417, for a device for emptying a portable receptacle, which device includes means for pushing or ejecting the contents of the receptacle therefrom.

491+, for a self-loading or unloading vehicle having a load

receiving portion which is pivotable relative to the horizontal, and wherein is provided a driven means for moving a load relative to the portion which movement may include removal from the portion.

497, for a self-loading or unloading vehicle having an elevatable load receiving portion and a load-handling means of the reciprocating conveyor type.

539+, for a self-loading or unloading vehicle having other loading or unloading means, and especially subclass 539 if the path of travel of the means represents an unprovided-for type of movement.

585, for the subcombination of a means, external to a vehicle, for the purpose of loading or unloading the vehicle, which means includes a load-engaging surface for pushing or pulling a load from the vehicle.

661, for an elevator or hoist which includes a carrier, and wherein the carrier includes a loading or unloading means in the nature of a push-pull device for moving a load laterally therefrom or thereto.

679+, for a vehicle having a load receiving portion, and a means for relocating a load of material therealong or therewithin.
