Abstract
Abstract An apparatus and method for disintegrating a can includes a feeding chute for feeding the cans into a cutter-compactor mechanism in which cutting blades are fixedly positioned on a rotating drum for cutting each can fed into the mechanism and driving the can further into the compacting portion of the drum. The rotating drum compacts the cans against a fixed arcuate surface and drops the cut and compacted can pieces into a receptacle. The rotating drum has annular raised sides for holding the cans therebetween and protruding cleats on its surface for dragging the cam into the compacting portion. The fixed compacting surface is arcuate to gradually compress the can being pulled against it as the space narrows between the surface and the rotating drum. The chute may have a ferrous can detector to eliminate ferrous cans from the unit, and the fixed compacting surface has a slot to allow the blades to pass therethrough as the drum rotates.

Claims Analysis
Total Claims: 19
Claim 1
Independent Claim
101 words
A can disintegrator apparatus comprising in combination: a frame; feed means chute for feeding cans, said feed means chute being attached to said frame; cutting means attached to said frame for cutting a can into a plurality of pieces; said cutting means having a plurality of cutting blades attached to a rotating drum; compacting means attached to said frame for crushing cans between two surfaces, one surface being the surface of said rotating drum having said cutting blades attached thereto; power means for driving said cutting means and compacting means; and receptacle means for receiving said cut and crushed can pieces.
Claim 2
Dependent Claim
101 words
A can disintegrator apparatus comprising in combination: a frame; feed means chute for feeding cans, said feed means chute being attached to said frame; cutting means attached to said frame for cutting a can into a plurality of pieces; said cutting means having a plurality of cutting blades attached to a rotating drum; compacting means attached to said frame for crushing cans between two surfaces, one surface being the surface of said rotating drum having said cutting blades attached thereto; power means for driving said cutting means and compacting means; and receptacle means for receiving said cut and crushed can pieces.
Claim 3
Dependent Claim
28 words
The apparatus in accordance with claim 1, in which said compacting means includes cleats fixedly attached to said rotating drum for driving cans against a second compacting surface.
Claim 4
Dependent Claim
23 words
The apparatus in accordance with claim 2, in which said second compacting surface is a fixed arcuate surface attached adjacent said rotating drum.
Claim 5
Dependent Claim
28 words
The apparatus in accordance with claim 3, in which said fixed, arcuate compacting surface has a slot formed therein for the passage of said cutting means cutting blades.
Claim 6
Dependent Claim
51 words
The apparatus in accordance with claim 4, in which said fixed arcuate compacting surface narrows the spacing between said rotating drum and said fixed compacting surface to a predetermined surface, thereby compacting said cans to a size to pass through the narrowed portion between said drum and said fixed compacting surface.
Claim 7
Dependent Claim
35 words
The apparatus in accordance with claim 5, in which said cutting means plurality of cutting blades extend radially on said drum in a single line, thereby requiring only one slot through said fixed compacting surface.
Claim 8
Dependent Claim
30 words
The apparatus in accordance with claim 6, in which said power means includes an electric motor driving a sprocket and chain to drive a sprocket attached to said rotating drum.
Claim 9
Dependent Claim
36 words
The apparatus in accordance with claim 7, in which said sprocket attached to said electric motor has a smaller diameter than the sprocket attached to said rotating drum to increase the torque of said rotating drum.
Claim 10
Dependent Claim
30 words
The apparatus in accordance with claim 8, in which said cutting means rotating drum has annular sides extending above the cylindrical base of the drum to maintain said cans therebetween.
Claim 11
Dependent Claim
22 words
The apparatus in accordance with claim 9, in which a safety grill is attached at the end of the feed means chute.
Claim 12
Dependent Claim
43 words
The apparatus in accordance with claim 1, in which said receptacle means is slotted for said cutting means blades to pass through the slots, whereby cut and crushed cans are collected by the receptacle while being retained from being thrown from the receptacle.
Claim 13
Dependent Claim
32 words
The apparatus in accordance with claim 11, in which said frame has an outer protective casing and a plurality of wheels mounted on the base thereof for moving said casing between positions.
Claim 14
Independent Claim
93 words
A method of disintegrating cans in a can disintegrator having a frame, rotating drum mounted thereto rotated by an electric motor, the drum having a plurality of blades mounted thereto, and forming one compressing surface adjacent a second compressing surface for compressing cans, the method comprising the steps of: feeding the cans down a chute; cutting said cans received from said chute with a plurality of blades on a rotating drum; compacting said cut cans between said rotating drum and a stationary surface; and directing said cut and compacted cans into a receptacle.
Claim 15
Independent Claim
93 words
A method of disintegrating cans in a can disintegrator having a frame, rotating drum mounted thereto rotated by an electric motor, the drum having a plurality of blades mounted thereto, and forming one compressing surface adjacent a second compressing surface for compressing cans, the method comprising the steps of: feeding the cans down a chute; cutting said cans received from said chute with a plurality of blades on a rotating drum; compacting said cut cans between said rotating drum and a stationary surface; and directing said cut and compacted cans into a receptacle.
Claim 16
Dependent Claim
21 words
The method in accordance with claim 13 including the step of driving said cut cans with cleats on said rotating drum.
Claim 17
Dependent Claim
28 words
The method in accordance with claim 14 in which the step of cutting said cans includes passing said blades through at least one slot in said stationary surface.
Claim 18
Dependent Claim
134 words
A can disintegrator apparatus comprising in combination: a casing having a liftable top portion thereof; a chute mounted to said casing for feeding cans thereinto; a rotating drum mounted in said casing and driven by an electric motor; plurality of cutting blades mounted to the base of said rotating drum for rotating therewith; a plurality of cleats attached to the base of said drum for rotation therewith; a fixed compacting surface attached in said casing and being slotted therein for the passage of said blades; and a receptacle for catching cut and compacted cans, whereby said blades on said rotating drum will cut cans fed from said chute into said casing and said cleats will feed said can pieces against said fixed compacting surface compacting said cans and feeding said cans into said receptacle.
Claim 19
Dependent Claim
134 words
A can disintegrator apparatus comprising in combination: a casing having a liftable top portion thereof; a chute mounted to said casing for feeding cans thereinto; a rotating drum mounted in said casing and driven by an electric motor; plurality of cutting blades mounted to the base of said rotating drum for rotating therewith; a plurality of cleats attached to the base of said drum for rotation therewith; a fixed compacting surface attached in said casing and being slotted therein for the passage of said blades; and a receptacle for catching cut and compacted cans, whereby said blades on said rotating drum will cut cans fed from said chute into said casing and said cleats will feed said can pieces against said fixed compacting surface compacting said cans and feeding said cans into said receptacle.
