Abstract
Abstract A load-compacting vehicle adapted to handle compressible refuse includes a wheeled chassis supporting a cylindrical barrel having a closed end and a door-like access end against which refuse can be compacted by a piston-like plunger contained in the barrel. The vehicle includes a ram device whereby the plunger can be advanced longitudinally of the barrel from the closed end to the access end to compress or expel refuse within the barrel depending upon whether the door-like access end is open or closed.

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
164 words
A load-compacting vehicle which includes plunger mounting means comprising: a pair of parallel rails which extend longitudinally within the vehicle barrel adjacent the top thereof and for substantially the full length thereof; first runner elements on said plunger by which it is mounted on said rails for load-compressing movement longitudinally of said barrel; an outrigger structure fixed on the ram device on which said plunger is mounted, and second runner elements on said outrigger structure which ride said rails and are spaced, axially of said barrel, from said first runner elements, said outrigger structure having a triangular frame spaced from said plunger and having a first apex portion fixed to a cylinder forming part of said ram device and second and third apex portions at which said second runner elements are respectively located; and a pair of diagonal struts having trailing ends fixed to said cylinder adjacent said plunger and leading ends joined to said triangular frame adjacent said second and third apex portions.
Claim 2
Dependent Claim

A load-compacting vehicle which includes plunger mounting means comprising: a pair of parallel rails which extend longitudinally within the vehicle barrel adjacent the top thereof and for substantially the full length thereof; first runner elements on said plunger by which it is mounted on said rails for load-compressing movement longitudinally of said barrel; an outrigger structure fixed on the ram device on which said plunger is mounted, and second runner elements on said outrigger structure which ride said rails and are spaced, axially of said barrel, from said first runner elements, said outrigger structure having a triangular frame spaced from said plunger and having a first apex portion fixed to a cylinder forming part of said ram device and second and third apex portions at which said second runner elements are respectively located; and a pair of diagonal struts having trailing ends fixed to said cylinder adjacent said plunger and leading ends joined to said triangular frame adjacent said second and third apex portions.
Claim 3
Dependent Claim
20 words
A vehicle according to claim 1 wherein said barrel has liquid drainage holes formed in its lower most floor portion.
Claim 4
Dependent Claim
24 words
A vehicle according to claim 2 which includes a launder mounted beneath said barrel as a catchment vessel for moisture expressed through said holes.
Claim 5
Dependent Claim
64 words
A vehicle according to claim 1 which includes: a. A compaction head able to enter said barrel through its rear end, b. means for axially advancing said head forwardly within and retracting it from said barrel, and c. mounting means for said head whereby it may be moved clear of said rear end so to permit loading of said barrel through said rear end.
Claim 6
Dependent Claim
53 words
A vehicle according to claim 4 wherein said means for axially advancing and retracting said head consist of at least one ram having said head mounted on its movable end and having its stationary end fixed on a carrier frame movable from and fixable in relation to the rear end of said barrel.
Claim 7
Dependent Claim
40 words
A vehicle according to claim 5 wherein the mounting means for said compaction head include a hinge-mounted door whereon said carrier frame is fixed and which can be swung clear of said open end or fixedly clamped in closure thereof.
