Apparatus for moving refuse from a bin

Claim 2

In an apparatus for feeding compactible material from a bin which has a front wall and a horizontally extending passageway extending upwardly from the bottom of the bin to the lower edge of the front wall which terminates at and extends across the top of the passageway, the apparatus having means for pushing material in the bin across the bottom of the bin into the passageway, the invention comprising: a. toothed means extending across the entrance to the passageway under the front wall at the top of the passageway and spaced above the pushing means entirely clear of the path of movement of said pushing means, said toothed means having a plurality of teeth projecting therefrom, and b. power means arranged to drive said toothed means in a direction where the teeth move continuously in a closed path with the teeth on the lowermost portion thereof traveling in said passageway in a direction opposite the direction in which said pushing means moves the material.

Claim 3

The invention defined in claim 1 wherein the toothed means is a roller and the teeth are carried on and project from the periphery of the roller, the power means for driving the roller rotating it in a direction where the teeth along the bottom quadrant of the roller travel counter to the direction in which the material is pushed by said pushing means and the teeth at the front of the roller move upwardly in a vertical arc.

Claim 4

The invention defined in claim 2 where the teeth are spaced from one another lengthwise of the roller and in staggered relation to one another about the periphery of the roller, and a comb element located below the front wall forwardly of the roller with spaced teeth thereon between which the teeth at the front of the roller pass, the teeth of the comb extending in a tangential direction with respect to the roller.

Claim 5

The invention defined in claim 3 wherein the free ends of the comb teeth ride against the surface of the roller.

Claim 6

The invention defined in claim 2 wherein the teeth are of ratchet shape with the leading face of the teeth being in a plane radial to the roller and the peripheries of the teeth sloping rearwardly inward from the leading face.

Claim 7

In an apparatus for feeding compactible material from a bin which has a front wall with a horizontally extending passageway therethrough extending upwardly from the bottom of the bin only partway up the full height of the front wall whereby the bin may hold compactible material to a level extending above the top of the passageway, the front wall of the bin having its lower edge terminating along the top of the passageway, the apparatus having a ram reciprocable over the bottom of the bin toward and away from the passageway for pushing material from the bin into and through the passageway, the invention comprising: a. a roller extending horizontally across the front of said passageway just below the front wall of the bin and spaced entirely above the plane of travel of the ram, b. means arranged to rotate said roller in a direction in which the lower portion of its periphery moves opposite to the direction of travel of material being pushed from the bin into and through said passageway, c. the periphery of the roll having spaced teeth projecting therefrom arranged to rake some of the material in the top of the mass of material that is being pushed by the ram into the passageway, and d. a comb fixed to the bin at the lower edge of the front wall in front of the roller having fingers between which the teeth on the front quadrant of the roller pass for cutting material that may be carried by the teeth against the comb.

Claim 8

In an apparatus for feeding compactible material from a bin which has a front wall with a horizontally extending passageway therethrough extending upwardly from the bottom of the bin only partway up the full height of the front wall whereby the bin may hold compactible material to a level extending above the top of the passageway, the front wall of the bin having its lower edge terminating along the top of the passageway, the apparatus having a ram reciprocable over the bottom of the bin toward and away from the passageway for pushing material from the bin into and through the passageway, the invention comprising: a. a roller extending horizontally across the front of said passageway just below the front wall of the bin and spaced entirely above the plane of travel of the ram, b. means arranged to rotate said roller in a direction in which the lower portion of its periphery moves opposite to the direction of travel of material being pushed from the bin into and through said passageway, c. the periphery of the roll having spaced teeth projecting therefrom arranged to rake some of the material in the top of the mass of material that is being pushed by the ram into the passageway, and d. a comb fixed to the bin at the lower edge of the front wall in front of the roller having fingers between which the teeth on the front quadrant of the roller pass for cutting material that may be carried by the teeth against the comb.
