Abstract
Abstract The crusher includes a swingable lever carrying a press plate which folds the closed end portion of the can outwardly over the main body of the can and smashes the main body downwardly as the lever is swung downwardly. By swinging the lever downwardly through an additional stroke, the press plate may be used to flatten the folded portion downwardly against the main body of the can.

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
230 words
In a device for crushing cylindrical cans, the combination of, a supporting bracket, means for anchoring said bracket rigidly to an upright member, a generally horizontal shelf rigid with said bracket and projecting outwardly therefrom, said shelf being adapted to support a can in a crushing position in which the can is disposed on its side on the shelf with the open end of the can facing away from said upright member and with the closed end of the can facing toward said member, an elongated lever overlying said shelf and pivotally connected to said bracket at a point located above the shelf, said lever being swingable upwardly away from said shelf to a raised position and downwardly toward said shelf to a lowered position, and a generally flat plate anchored rigidly to said lever and located beneath the latter, said plate being disposed in substantially horizontal overlying relation with said shelf when said lever is in said lowered position and having an inner edge spaced outwardly from the inner end of said shelf whereby the closed end portion of a can placed on said shelf in said crushing position is engaged and folded outwardly over the body of the can by said edge and the body of the can is smashed downwardly by said plate as said lever is swung downwardly from said raised position to said lowered position.
Claim 2
Dependent Claim
230 words
In a device for crushing cylindrical cans, the combination of, a supporting bracket, means for anchoring said bracket rigidly to an upright member, a generally horizontal shelf rigid with said bracket and projecting outwardly therefrom, said shelf being adapted to support a can in a crushing position in which the can is disposed on its side on the shelf with the open end of the can facing away from said upright member and with the closed end of the can facing toward said member, an elongated lever overlying said shelf and pivotally connected to said bracket at a point located above the shelf, said lever being swingable upwardly away from said shelf to a raised position and downwardly toward said shelf to a lowered position, and a generally flat plate anchored rigidly to said lever and located beneath the latter, said plate being disposed in substantially horizontal overlying relation with said shelf when said lever is in said lowered position and having an inner edge spaced outwardly from the inner end of said shelf whereby the closed end portion of a can placed on said shelf in said crushing position is engaged and folded outwardly over the body of the can by said edge and the body of the can is smashed downwardly by said plate as said lever is swung downwardly from said raised position to said lowered position.
Claim 3
Dependent Claim
38 words
A device as defined in claim 1 in which roughened serrations are formed on the underside of said plate to help drag the can inwardly between said plate and said shelf during folding and smashing of the can.
Claim 4
Dependent Claim
46 words
A device as defined in claim 2 in which the free outer edge of said shelf is turned downwardly to facilitate inward movement of the open end of the can across said outer edge as the can is dragged inwardly between said plate and said shelf.

A device as defined in claim 1 in which a generally horizontal pin connects said lever to said bracket, and a friction washer telescoped over said pin to hold said lever releasably in said raised position.
Claim 6
Dependent Claim
56 words
A device as defined in claim 1 in which a vertical plate is joined to the upper side of said horizontal plate approximately midway between the side edges thereof and is connected to the underside of said lever, the inner edge of said vertical plate being spaced outwardly from said inner edge of said horizontal plate.
Claim 7
Dependent Claim
73 words
A device as defined in claim 1 in which said bracket comprises an upper vertical portion supporting said lever, said shelf comprising a metal sheet joined integrally to and projecting horizontally from the lower end of said vertical portion, an L-shaped brace having a horizontal leg joined to and underlying said shelf and having a vertical leg lying alongside said upright member, and a reinforcing web joined to and extending between said legs.
