Abstract
Abstract A two-station trash compactor including a frame supported carriage movable in a longitudinal path of travel between a pair of longitudinally spaced, trash compacting stations, homing apparatus for guiding the carriage to the trash compacting station, a compacting ram vertically movable on the carriage between a raised position and a lowered trash compacting position for selectively compacting trash in either of a pair of longitudinally spaced, partible trash containers at the trash compacting stations, and ram driving apparatus on the carriage for moving the compacting ram in a to-and-fro vertical path of travel to compact the trash a predetermined amount and then automatically returning the compacting ram to a removed position.

Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
84 words
A two-station trash compactor comprising: a frame; a transfer carriage longitudinally movable on said frame between first and second longitudinally spaced trash compacting stations; ram means movable on said carriage in a to-and-fro path of travel for selectively compacting trash at said first and second stations; and locator means including means resisting movement of said carriage from each station until said carriage is moved a predetermined distance from said station and then permitting said carriage to freely move toward the other of said stations.
Claim 2
Dependent Claim
84 words
A two-station trash compactor comprising: a frame; a transfer carriage longitudinally movable on said frame between first and second longitudinally spaced trash compacting stations; ram means movable on said carriage in a to-and-fro path of travel for selectively compacting trash at said first and second stations; and locator means including means resisting movement of said carriage from each station until said carriage is moved a predetermined distance from said station and then permitting said carriage to freely move toward the other of said stations.
Claim 3
Dependent Claim
53 words
The apparatus of claim 1 wherein said locator means includes roller means on one of said frame and said carriage and cooperating socket means on the other of said frame and carriage for receiving said roller means, said socket means being positioned such that said roller means moves vertically to be received thereby.
Claim 4
Dependent Claim
42 words
The trash compactor of claim 1 wherein said ram means comprises a convergent axial end compressing face for camming relatively radially disposed trash toward the axis of said compacting ram means as said ram means moves axially forwardly to compress said trash.
Claim 5
Dependent Claim
46 words
The apparatus set forth in claim 1 including: trash container means for receiving trash to be compressed; and a dolly supporting said trash container means and being movable between a position remote from said frame and a frame engaging position in response to trash being compacted.
Claim 6
Dependent Claim
64 words
The apparatus of claim 4 wherein said trash container means includes a platform, first and second partible container side wall portions relatively movable between abutting trash receiving positions and spread apart trash emptying positions, said first side wall portion being mounted on said platform for swinging movement about a horizontal axis to relatively move said side wall portions between said abutting and spread positions.
Claim 7
Dependent Claim
76 words
The compactor as set forth in claim 1 wherein said frame includes longitudinal track means having longitudinally spaced apart, socket means at said first and second stations, said carriage including laterally spaced rollers on said track meanS receivable in said socket means when said carriage is moved to said first and second stations; said locator means including means yieldably urging said carriage toward said track to resist movement of said rollers out of said socket means.
Claim 8
Dependent Claim
39 words
The apparatus set forth in claim 6 including means reactable between said carriage and said frame for longitudinally moving said carriage out of said homing position at said first and second stations against the force of said yieldable means.
Claim 9
Dependent Claim
125 words
The apparatus set forth in claim 6 wherein said track means comprises at least one pair of laterally spaced longitudinal tracks, said socket means comprising at least one socket in one of said tracks adjacent said first station and at least another socket in the other track adjacent said other station; said roller means including at least one pair of rollers on said compacting ram means and positioned such that one roller is in longitudinal alignment with said one track and receivable in the socket at said first station when the carriage is at said first station and a second roller in longitudinal alignment with said second track and receivable in the socket at said second station when said carriage is at said second station.
