Abstract

Abstract A compactor which includes a housing and a ram mounted in the housing for vertically reciprocal movement and a refuse receiving drawer which is slidable into and out of the housing between a compacting position beneath the ram and a noncompacting position outwardly of the housing. The drawer is resiliently mounted with respect to the housing to permit the drawer to move a small distance vertically when compacting forces exerted by the ram exceed a certain amount so that this excess load is transferred from the drawer slides to the base of the housing.

Claims Analysis

Total Claims: 14
Claim 1
Independent Claim 85 words
A compactor comprising: a. a compactor housing, b. a ram mounted in said housing for vertically reciprocal movement therein, c. a slidably mounted refuse receiving drawer, d. means supporting said drawer for translational movement between a compacting position beneath said ram and a noncompacting position displaced outwardly of said compacting position, and e. means in engagement with said drawer supporting means for permitting limited yielding movement of said drawer under compacting movement of said ram sufficient to relieve compacting forces from said drawer supporting means.
Claim 2
Dependent Claim 85 words
A compactor comprising: a. a compactor housing, b. a ram mounted in said housing for vertically reciprocal movement therein, c. a slidably mounted refuse receiving drawer, d. means supporting said drawer for translational movement between a compacting position beneath said ram and a noncompacting position displaced outwardly of said compacting position, and e. means in engagement with said drawer supporting means for permitting limited yielding movement of said drawer under compacting movement of said ram sufficient to relieve compacting forces from said drawer supporting means.
Claim 3
Dependent Claim 14 words
The compactor of claim 1 wherein: a. said supporting means includes opposed drawer slides.
Claim 4
Dependent Claim 39 words
The compactor of claim 2 wherein said means for permitting yielding movement comprises: a. resilient means permitting limited vertical movement of said drawer with respect to said housing in response to forces exerted in said receptacle by said ram.
Claim 5
Dependent Claim 55 words
The compactor of claim 3 further comprising: a. slide carrier plates, b. means attaching said drawer slides to said carrier plates, c. means slidably mounting said carrier plates to said housing for limited vertical movement with respect thereto, and d. said resilient means resisting sliding movement of said carrier plates with respect to said housing.
Claim 6
Dependent Claim 41 words
The compactor of claim 3 further comprising: a. bracket members having portions engaging said slides, b. means pivotally mounting said bracket members on said drawer, and c. said resilient means resisting pivotal movement of said brackets with respect to said drawer.
Claim 7
Dependent Claim 111 words
The compactor of claim 1 wherein: a. said housing includes a top, a base and opposed uprights extending between said top and base, b. said drawer has opposed side walls, an open top and a bottom wall, c. bracket members are pivotally mounted on outer surfaces of said drawer side walls, d. said drawer supporting means includes opposed drawer slides mounted on said uprights, e. portions of said brackets spaced from the pivotal connections thereof engage said drawer slides, and f. spring members are attached to and extend between said drawer and said brackets and yieldably maintain said drawer bottom wall and said housing base in spaced relationship to each other.
Claim 8
Dependent Claim 118 words
A compactor comprising: a. a compactor housing having a top, a base and opposed uprights extending between said top and said base, b. a ram mounted in said housing for vertically reciprocal movement toward and away from said base, c. a plurality of slide carrier plates, d. means mounting said carrier plates on said uprights for slidable movement therealong, e. means resiliently urging said carrier plates upwardly with respect to said uprights, f. substantially horizontally extending drawer slides attached to said carrier plates and extending between said uprights, and g. an open top drawer slidably supported on said drawer slides for sliding movement between a compacting position beneath said ram and a noncompacting displaced from said compacting position.
Claim 9
Dependent Claim 118 words
A compactor comprising: a. a compactor housing having a top, a base and opposed uprights extending between said top and said base, b. a ram mounted in said housing for vertically reciprocal movement toward and away from said base, c. a plurality of slide carrier plates, d. means mounting said carrier plates on said uprights for slidable movement therealong, e. means resiliently urging said carrier plates upwardly with respect to said uprights, f. substantially horizontally extending drawer slides attached to said carrier plates and extending between said uprights, and g. an open top drawer slidably supported on said drawer slides for sliding movement between a compacting position beneath said ram and a noncompacting displaced from said compacting position.
Claim 10
Dependent Claim 121 words
A compactor comprising: a. a compactor housing, b. a ram mounted in said housing for vertically reciprocal movement therein, c. a refuse receiving receptacle, d. opposed drawer slides slidably supporting said receptacle for movement between a compacting position beneath said ram and a noncompacting position displaced outwardly of said compacting position, e. slide carrier plates, f. means attaching said drawer slides to said carrier plates, g. means slidably mounting said carrier plates to said housing for limited vertical movement with respect thereto, and h. resilient means resisting sliding movement of said carrier plates with respect to said housing and permitting limited yielding movement of said receptacle under compacting movement of said ram sufficient to relieve compacting forces from said drawer slides.
Claim 11
Dependent Claim 121 words
A compactor comprising: a. a compactor housing, b. a ram mounted in said housing for vertically reciprocal movement therein, c. a refuse receiving receptacle, d. opposed drawer slides slidably supporting said receptacle for movement between a compacting position beneath said ram and a noncompacting position displaced outwardly of said compacting position, e. slide carrier plates, f. means attaching said drawer slides to said carrier plates, g. means slidably mounting said carrier plates to said housing for limited vertical movement with respect thereto, and h. resilient means resisting sliding movement of said carrier plates with respect to said housing and permitting limited yielding movement of said receptacle under compacting movement of said ram sufficient to relieve compacting forces from said drawer slides.
Claim 12
Dependent Claim 32 words
The compactor of claim 8 wherein said mounting means comprises: a. vertically extending slots formed in portions of said housing, and B. bolt members extending through said carrier plates and said slots.
Claim 13
Dependent Claim 93 words
A compactor comprising: a. a compactor housing, b. a ram mounted in said housing for vertically reciprocal movement therein, c. a refuse receiving drawer, d. drawer slides supporting said drawer for translational movement between a compacting position beneath said ram and a noncompacting position cantilevered outwardly of said compacting position and supported by said slides, and e. spring means attached to said drawer slides and permitting limited yielding movement of said drawer slides with respect to said housing under compacting movement of said ram sufficient to relieve compacting forces from said drawer slides.
Claim 14
Dependent Claim 93 words
A compactor comprising: a. a compactor housing, b. a ram mounted in said housing for vertically reciprocal movement therein, c. a refuse receiving drawer, d. drawer slides supporting said drawer for translational movement between a compacting position beneath said ram and a noncompacting position cantilevered outwardly of said compacting position and supported by said slides, and e. spring means attached to said drawer slides and permitting limited yielding movement of said drawer slides with respect to said housing under compacting movement of said ram sufficient to relieve compacting forces from said drawer slides.
