Abstract

A refuse collection and delivery system, which includes a garbage can for collection garbage and a garbage truck for receiving and delivering the garbage collected from the garbage can. The garbage can includes a horizontal type cylinder having an opening covered with a sliding cover which has lifting-eyes thereon for the fastening therein of the hooks of a crane of the garbage truck to lift the garbage can to a dustbin tipping device thereof for dust-free tipping operation.

Claims

1. A refuse collection and delivery system, including a garbage can, a stand for the garbage can, and a garbage truck:

said garbage can comprising a horizontal cylindrical wall defining the can central axis, and two circular end walls extending normal to said central axis at opposite ends of said cylindrical wall;

said cylindrical wall having an upwardly facing opening extending therealong for placement of garbage into the can;

said circular end walls having peripheral edges formed with drive teeth extending therealong to facilitate overturnment of the garbage can for emptying purposes;

a stub axle extending from each end wall on the can central axis;

a slidable cover for said garbage can, comprising an arcuate segmental main wall coextensive in length with the garbage can, and two end walls extending normal to said arcuate wall alongside a respective one of the can end walls;

each cover end wall having a sleeve telescoped onto one of said stub axles whereby the cover can be rotated around the can central axis to alternately expose or cover the can opening;

the thickness of each cover end wall being relatively small at its connection point to the cover main wall and being relatively great at a point diammetrically spaced from said connection point so that the center of gravity of the cover is lowered to cause the cover to be gravitationally biased to a position overlying the can opening;

a plurality of lifting eyes extending from the cover main wall at axially spaced points therealong;

said stand comprising faces upright blocks spaced apart in a rectangular pattern, and connector means extending between said blocks to form a rigid unitary cradle structure for supporting the garbage can in a horizontal attitude; and

a resilient cushion carried on each block for engagement with the undersurface of the can;

said garbage truck comprising a block and tackle means having a hook structure engageable with said lifting eyes, whereby the cover and garbage can are liftable as a unit from the stand;

an upwardly open bin structure (33);

a lid (31) normally closing said bin structure;

power means (34) for moving the lid structure to an open position; and

two pairs of horizontal axis drive wheels (27) located at the mouth of the bin structure to mate with the drive teeth on the garbage can when the block and tackle means is operated to lower the garbage can toward the bin structure;

said drive wheels being rotatable to overturn the garbage can while the cover remains in a stationary position above the bin structure, whereby garbage is discharged from the overturned can into the bin structure.

2. The collection and delivery system of claim 1, and further comprising two circumferential structural reinforcement ribs on the cover;

said lifting eyes including two spaced lifting eyes on one of said ribs and two additional lifting eyes on the other rib.

3. The collection and delivery system of claim 1, and further comprising an anti-friction guide means between each cover end wall and each adjacent can end wall;

each anti-friction guide means comprising an arcuate groove on one of said end walls and a plurality of anti-friction balls rotatably positioned in said groove.

4. The collection and delivery system of claim 1, and further comprising means in the garbage can for extinguishing cigarette butts;

said extinguishing means comprising a water containment device on one of the garbage can end walls near the plane of the can opening.

5. The collection and delivery system of claim 1, and further comprising an observation window on a wall of the dust bin structure, whereby a person can observe the garbage discharge action achieved by overturnment of the garbage can.
