Abstract
Abstract This invention relates generally to devices designed to crush metal cans such as beverage containers and the like. More specifically, this invention relates to a can crushing device having a base upon which to place the can to be crushed and having a means for criming one side of said can when pressure is applied to the top of said can by a pressure exerting means connected to said base. Said device further has means for allowing air to escape from said can when the same is being crushed.

Claims Analysis
Total Claims: 5
Claim 1
Independent Claim
228 words
A can crushing apparatus comprising: (a) means for holding a can in a substantially upright position; (b) means for applying compression pressure to said can longitudinally thereof further comprising: (1) a base having a ridge attached thereto such that the upper portion of said ridge contacts the edge of said can and its longitudinal axis is oblique to the tangent of the perimeter of said can at the point of contact; (2) an upright member attached to said base; (3) a mounting member attached to said upright member; (4) a press member slideably attached to said mounting member having means for allowing air to escape said can; and (5) a handle having a first lever rotatably attached at one end to said mounting member and a second lever attached to said first lever at the end opposite the point of attachment to said mounting member and attached to said press member at a point remote from either end; and (c) a means for crimping at least one side of said can along a substantially vertical first line, thence sequentially about the sides of said can, and terminating along a substantially vertical line second line opposite said first line; whereby a can held by said holding means may be compressed between said base and said press member to produce a circular package of concentrated mass with no cut edges.
Claim 2
Dependent Claim
228 words
A can crushing apparatus comprising: (a) means for holding a can in a substantially upright position; (b) means for applying compression pressure to said can longitudinally thereof further comprising: (1) a base having a ridge attached thereto such that the upper portion of said ridge contacts the edge of said can and its longitudinal axis is oblique to the tangent of the perimeter of said can at the point of contact; (2) an upright member attached to said base; (3) a mounting member attached to said upright member; (4) a press member slideably attached to said mounting member having means for allowing air to escape said can; and (5) a handle having a first lever rotatably attached at one end to said mounting member and a second lever attached to said first lever at the end opposite the point of attachment to said mounting member and attached to said press member at a point remote from either end; and (c) a means for crimping at least one side of said can along a substantially vertical first line, thence sequentially about the sides of said can, and terminating along a substantially vertical line second line opposite said first line; whereby a can held by said holding means may be compressed between said base and said press member to produce a circular package of concentrated mass with no cut edges.
Claim 3
Dependent Claim
61 words
A can crushing apparatus as described in claim 1 wherein said means for holding a can comprises: (a) said base; (b) a plurality of stops arranged oblique to one another attached to said base, and (c) said ridge opposite said stops, whereby a can placed on said base rests against said stops and on said ridge is thereby held in place.
Claim 4
Dependent Claim
169 words
A can crushing apparatus comprising: (a) a flat base; (b) a support attached to said base; (c) a hollow tubular member attached to said support with its longitudinal axis perpendicular to said base; (d) a shaft having upper and lower ends, adapted for insertion into said tubular member and slideable therein; (e) a handle attached to the upper end of said shaft, (f) a compression plate attached to the lower end of said shaft in a parallel planar disposition relative to said base, (g) a ridge on said base and adapted to have a can positioned thereon so that said ridge contacts at one point the edge of one end of the can, (h) a plurality of stops attached to said base such that a can placed against said stops in a substantially vertical position will be underneath said compression plate, whereby said handle may be activated and said plate compresses said can against said base and said ridge crimps said can at said point thereby crushing the same.
