Abstract
Abstract The combination of a storage bin, such as a dumpster container for trash and refuse, with a compactor adapted to convey a solids or particulate material thereto, wherein the compactor incorporates a compactor ram having a face plate releasably latched to the forward or head end of the ram. When the dumpster container is full, the face plate is adapted to be detached from the ram and concurrently fastened to the storage bin to constitute a closure for the material inlet opening of the container so as to prevent spills of trash therefrom.

Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
340 words
In the combination of a storage bin having at least one opening for the inlet of material into said bin with a compactor communicating with said opening; hopper means for supplying solids material into said compactor; and compactor ram means reciprocable within said compactor for conveying the material from said compactor through said inlet opening into the storage bin; the improvement comprising: a face plate mounted on the forward end of said compactor ram and being adapted to enter said bin opening during the compacting stroke of said ram towards the bin, said face plate having peripheral dimensions in substantial conformance with the size of said bin inlet opening; latch means on said face plate normally engaging means on said compactor ram for releasably fastening said face plate to said compactor ram; resilient biasing means normally biasing said latch means into a latching position for fastening said face plate to the head end of said compactor ram; means engageable with said storage bin and said face plate when the latter is in a predetermined position within the bin opening for biasing said latch means into an unlatching position releasing said face plate from said compactor ram and concurrently locking said face plate to said storage bin to form a closure for said inlet opening; a guide frame fastened to the head end of said compactor ram circumferentially encompassing said face plate, said guide frame guiding said face plate into said latching engagement with the compactor ram, recesses formed in said guide frame in axial alignment with the latch means of said face plate; at least one conduit means on said face plate in axial alignment with said recesses and a through-bore in said storage bin axially aligned with said recesses and said latch means in the forward position of said compactor ram, said engaging means being insertable through said through-bore, recesses and conduit means to bias said latch means into a position for releasing said face plate from said compactor ram and locking said face plate to said storage bin.
Claim 2
Dependent Claim
340 words
In the combination of a storage bin having at least one opening for the inlet of material into said bin with a compactor communicating with said opening; hopper means for supplying solids material into said compactor; and compactor ram means reciprocable within said compactor for conveying the material from said compactor through said inlet opening into the storage bin; the improvement comprising: a face plate mounted on the forward end of said compactor ram and being adapted to enter said bin opening during the compacting stroke of said ram towards the bin, said face plate having peripheral dimensions in substantial conformance with the size of said bin inlet opening; latch means on said face plate normally engaging means on said compactor ram for releasably fastening said face plate to said compactor ram; resilient biasing means normally biasing said latch means into a latching position for fastening said face plate to the head end of said compactor ram; means engageable with said storage bin and said face plate when the latter is in a predetermined position within the bin opening for biasing said latch means into an unlatching position releasing said face plate from said compactor ram and concurrently locking said face plate to said storage bin to form a closure for said inlet opening; a guide frame fastened to the head end of said compactor ram circumferentially encompassing said face plate, said guide frame guiding said face plate into said latching engagement with the compactor ram, recesses formed in said guide frame in axial alignment with the latch means of said face plate; at least one conduit means on said face plate in axial alignment with said recesses and a through-bore in said storage bin axially aligned with said recesses and said latch means in the forward position of said compactor ram, said engaging means being insertable through said through-bore, recesses and conduit means to bias said latch means into a position for releasing said face plate from said compactor ram and locking said face plate to said storage bin.
Claim 3
Dependent Claim
25 words
The combination as claimed in claim 1, said engaging means comprising an elongate rod member extending through said through-bore, said recesses and said conduit means.
Claim 4
Dependent Claim
107 words
The combination as claimed in claim 1, comprising further recesses in said guide frame in parallel spaced relationship with said first recesses; a further through-bore in said storage bin in alignment with said further recesses and conduit means upon said face plate being located in the inlet opening towards the forward stroke of said compactor ram; and means adapted to extend through said further through-bore, further recesses and conduit means for fastening said face plate to said storage bin to prevent pivoting of said face plate within said inlet opening when said face plate is attached to said storage bin as a cover for said inlet opening.
Claim 5
Dependent Claim
27 words
The combination as claimed in claim 3, said extending means comprising an elongate rod member adapted to extend through said further through-bore, further recesses and conduit means.
Claim 6
Dependent Claim
16 words
