Abstract
Abstract A device for crushing containers embodies a base having a supporting surface for receiving the container to be crushed. Upstanding crushing members are mounted for rectilinear movement along the supporting surface selectively to a first position in spaced relation to each other for receiving the container to be crushed and to a second position with the crushing members being juxtaposed relative to each other to crush the container. Elongated power transmitting members are connected to the crushing members and are mounted for sliding movement along the supporting surface. A power transmitting element is mounted for rotation above each power transmitting member and imparts rectilinear movement thereto and to the crushing members carried thereby selectively to their first and second positions.

Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
165 words
A device for crushing containers comprising: (a) a base having a supporting surface adapted to receive a container to be crushed, (b) a pair of upstanding oppositely disposed crushing members mounted for rectilinear movement along said supporting surface selectively to a first position with said upstanding members being spaced from each other for receiving the container to be crushed and to a second position with said upstanding members being juxtaposed relative to each other to crush said container, (c) an upwardly opening longitudinally extending recess in said supporting surface, (d) a pair of elongated power transmitting members mounted for sliding movement within said recess with the innermost end of each said power transmitting member secured to the upstanding crushing member adjacent thereto, and (e) a power transmitting element mounted for rotation above and operatively connected to each said elongated power transmitting member and adapted to impart rectilinear movement thereto to move its upstanding crushing member selectively to said first position and to said second position.
Claim 2
Independent Claim
165 words
A device for crushing containers comprising: (a) a base having a supporting surface adapted to receive a container to be crushed, (b) a pair of upstanding oppositely disposed crushing members mounted for rectilinear movement along said supporting surface selectively to a first position with said upstanding members being spaced from each other for receiving the container to be crushed and to a second position with said upstanding members being juxtaposed relative to each other to crush said container, (c) an upwardly opening longitudinally extending recess in said supporting surface, (d) a pair of elongated power transmitting members mounted for sliding movement within said recess with the innermost end of each said power transmitting member secured to the upstanding crushing member adjacent thereto, and (e) a power transmitting element mounted for rotation above and operatively connected to each said elongated power transmitting member and adapted to impart rectilinear movement thereto to move its upstanding crushing member selectively to said first position and to said second position.
Claim 3
Dependent Claim
29 words
A device for crushing containers as defined in claim 1 in which each said power transmitting member is a rack and each said power transmitting element is a pinion.
Claim 4
Dependent Claim
81 words
A device for crushing containers as defined in claim 1 in which an elongated lever arm is connected at one end to each said power transmitting element and is disposed for pivotal movement selectively to an inoperative position with said lever arm extending upwardly and positioning its upstanding crushing members in said first position and to an operative position with said lever arms extending in generally horizontal directions away from each other and urging said crushing members toward said second position.
Claim 5
Dependent Claim
33 words
A device for crushing containers as defined in claim 3 in which each said upstanding crushing member is inclined upwardly and inwardly at an acute angle relative to a vertical plane passing therethrough.
Claim 6
Dependent Claim
18 words
A device as defined in claim 4 in which said acute angle ranges from approximately 3° to 7°.
Claim 7
Dependent Claim
15 words
A device as defined in claim 5 in which said acute angle is approximately 5°.
Claim 8
Dependent Claim
16 words
A device as defined in claim 4 in which said upstanding crushing members are plate-like members.
Claim 9
Dependent Claim
59 words
A device as defined in claim 4 in which the axis of rotation of each said power transmitting element is spaced from its crushing member while in said second position so that final movement of the lever arms away from each other imparts upward movement to said crushing members to position said crushing members generally parallel to each other.
