Refuse holding vehicle
First Claim
1. A packer assembly for use on a refuse handling vehicle equipped with a refuse receiving and storage body having a lower first surface, a hopper communicating with said body such that refuse may be transferred from said hopper into said body by said packer assembly, said hopper having a floor contiguous with said lower surface and an onboard source of pressurized fluid, comprising:
- a platen mounted at one end thereof for rotation within said hopper for urging refuse within said hopper into said body;
a shaft fixedly coupled to said platen; and
drive means coupled to said shaft for imparting reciprocal rotary motion to said platen alternately in clockwise and counter-clockwise cycles such that for any movement of said platen in either direction, the speed of movement of said platen will decrease throughout the cycle and the force exerted by said platen on said refuse will increase throughout said cycle, said drive means including;
a segment sprocket having a semicircular portion with a center, a non-semicircular portion and an aperture spaced from said center for receiving said shaft;
a flexible multi-jointed link member for engaging said semicircular portion; and
motor means coupled to said link member for alternately rotating said segment sprocket in clockwise and counter-clockwise directions.

Abstract
A refuse collection and storage body is carried by the frame of a truck chassis having a cab at the forward end thereof. A hopper having a rotatably reciprocal platen therein resides at the forward end of the body. Refuse within the body is discharged through an openable tailgate assembly at the rear of the body. A fixed length arm is pivotly connected at one end thereof to a carriage which is reciprocally movable along a transverse support beam. The arm, having refuse container gripping arms at the free end thereof, is rotatably elevatable for dumping the contents of the container into the hopper. The several movable components are responsive to a control apparatus located within the cab.
