Abstract
Abstract In a refuse compaction and ejection system for location adjacent to a wall, truck cab, or other body which would restrict vertical angular movement due to lack of free space therebetween, a body slide-lift mechanism for shifting the refuse storage compartment rearward in combination with vertical movement to adjust the level of refuse ejection to a desired height. The refuse storage compartment containing the appropriate compaction and ejection components is rotatably affixed at its forward end to a support base by means of a slotted flange-pin assembly. A support-base-mounted hydraulic cylinder oriented along the length of and attached to the floor of the storage compartment provides the power to reciprocate the compartment from its horizontal, adjacent location to its extended, elevated ejection level.

Claim 1
Independent Claim
208 words
In a material compaction and ejection system having a storage compartment with height adjustable rearward ejection means and being affixed to a supporting base, an improved body lift mechanism for displacing said compartment away from an obstructing object and adjusting said rearward ejection means to variable heights comprising: a. guide means immovably attached to said support base and operable in combination with said affixing means to permit limited reciprocal movement of said storage compartment from a front limiting point to a rearward limiting point along a length of said support base; b. power means for applying reciprocating force with respect to said storage compartment, said force including vertical and horiziontal components, said vertical component being applied at a rearward part of said storage compartment and operable to raise said ejection means to a desired height with respect to said support base; and c. connecting means from a front portion of said storage compartment to said support base, said connecting means being operable in combination with said guide means to permit said limited reciprocating movement along said guide means, said connecting means further permitting angular vertical movement of said storage compartment about an axis normal to said reciprocating movement and forward of said rearward part of vertical force application.
Claim 2
Dependent Claim
208 words
In a material compaction and ejection system having a storage compartment with height adjustable rearward ejection means and being affixed to a supporting base, an improved body lift mechanism for displacing said compartment away from an obstructing object and adjusting said rearward ejection means to variable heights comprising: a. guide means immovably attached to said support base and operable in combination with said affixing means to permit limited reciprocal movement of said storage compartment from a front limiting point to a rearward limiting point along a length of said support base; b. power means for applying reciprocating force with respect to said storage compartment, said force including vertical and horiziontal components, said vertical component being applied at a rearward part of said storage compartment and operable to raise said ejection means to a desired height with respect to said support base; and c. connecting means from a front portion of said storage compartment to said support base, said connecting means being operable in combination with said guide means to permit said limited reciprocating movement along said guide means, said connecting means further permitting angular vertical movement of said storage compartment about an axis normal to said reciprocating movement and forward of said rearward part of vertical force application.
Claim 3
Dependent Claim
56 words
A system as defined in claim 1, wherein said guide means comprises flange members, each having a slotted opening and protruding from forward, lateral base portions of said storage compartment in parallel orientation with said reciprocating movement, said slotted openings being operable to define a path for said reciprocating movement between front and rearward limiting points.
Claim 4
Dependent Claim
45 words
A system as defined in claim 2, wherein said connecting means comprises pins immovably affixed to said support base in orientation such that said affixed pins traverse said slotted openings and operate to limit the reciprocating movement of said storage compartment to said reciprocating path.
Claim 5
Dependent Claim
55 words
A system as defined in claim 1, wherein said guide means comprises flange members each having a slotted opening and protruding from forward lateral portions of said support base in parallel orientation with said reciprocating movement, said slotted openings being operable to define a path for said reciprocating movement between front and rearward limiting points.
Claim 6
Dependent Claim
45 words
A system as defined in claim 4, wherein said connecting means comprises pins immovable affixed to said storage compartment in orientation such that said affixed pins traverse said slotted openings and operate to limit the reciprocating movement of said storage compartment to said reciprocating path.
Claim 7
Dependent Claim
17 words
A system as defined in claim 1, wherein said power means comprises an hydraulic cylinder power mechanism.
Claim 8
Dependent Claim
26 words
A system as defined in claim 1, wherein said system is used in combination with a mobile vehicle whose structure, in part, comprises said obstructing object.
Claim 9
Dependent Claim
35 words
A system as defined in claim 1 wherein said system is affixed in a stationary location, said ejection of compacted material being to a receiving means which is transported to said location for material pickup.
Claim 10
Dependent Claim
12 words
A system as defined in claim 1 wherein said material is refuse.
