Abstract
Abstract A device for crushing metal cans and other objects comprises a rectangular base and two pairs of pivotal lever arms. The lever arms of each pair rotate toward each other about parallel axes located along opposite sides of the base. In operation, a can is placed on its side in the base, the lever arms of one pair are brought together to flatten a zone across the cylindrical wall of the can, and the lever arms of the other pair are then rotated against the ends of the can to complete the crushing operation.

Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
249 words
A device for crushing objects, such as individual metal cans, comprising a base for supporting an object to be crushed, the base having a major and a minor axis and at least one member defining a support plane of the base against which the object is to be crushed; at least one first lever mounted on the base, generally adjacent the center of the major axis of the base, for pivotal movement about an axis spaced laterally from and oriented generally parallel to the major axis of the base and located above and oriented generally parallel to the support plane of the base, said lever having an elongated handle and a portion located and formed for engagement with a first portion of an object supported on the base upon pivoting of the lever about its axis toward said object, thereby to flatten said first portion of the object; and at least one second lever mounted on the base, generally adjacent the center of the minor axis of the base, for pivotal movement about an axis spaced longitudinally from and oriented generally parallel to the minor axis of the base and located above and oriented generally parallel to the support plane of said base, said second lever having an elongated handle and a portion located and formed for engagement with a second portion of an object supported on the base upon pivoting of the lever about its axis toward said object, thereby to flatten said second portion of the object.
Claim 2
Independent Claim
249 words
A device for crushing objects, such as individual metal cans, comprising a base for supporting an object to be crushed, the base having a major and a minor axis and at least one member defining a support plane of the base against which the object is to be crushed; at least one first lever mounted on the base, generally adjacent the center of the major axis of the base, for pivotal movement about an axis spaced laterally from and oriented generally parallel to the major axis of the base and located above and oriented generally parallel to the support plane of the base, said lever having an elongated handle and a portion located and formed for engagement with a first portion of an object supported on the base upon pivoting of the lever about its axis toward said object, thereby to flatten said first portion of the object; and at least one second lever mounted on the base, generally adjacent the center of the minor axis of the base, for pivotal movement about an axis spaced longitudinally from and oriented generally parallel to the minor axis of the base and located above and oriented generally parallel to the support plane of said base, said second lever having an elongated handle and a portion located and formed for engagement with a second portion of an object supported on the base upon pivoting of the lever about its axis toward said object, thereby to flatten said second portion of the object.
Claim 3
Dependent Claim
24 words
A device according to claim 1 wherein the pivotal axes of the first and second levers are oriented generally perpendicular relative to one another.
Claim 4
Dependent Claim
62 words
A device according to claim 1 wherein there are two first lever arms mounted on the base for pivotal movement about two laterally spaced and parallel axes, one on either side of the major axis of the base, said first lever arms being positioned and configured such that the object-engaging portions thereof coact to flatten the said first portion of the object.
Claim 5
Dependent Claim
61 words
A device according to claim 1 wherein there are two second lever arms mounted on the base for pivotal movement about two laterally spaced and parallel axes, one on either side of the minor Axis of the base, said second lever arms being positioned and configured such that the object-engaging portions thereof act to flatten two second portions of said object.
Claim 6
Independent Claim
297 words
A device for crushing objects, such as individual metal cans, comprising a base for supporting an object to be crushed, the base having a major and a minor axis and at least one member defining a support plane of the base against which the object is to be crushed; two first lever arms mounted on the base, generally adjacent to the center of the major axis of the base, for pivotal movement about two axes oriented generally parallel to the major axis of the base, spaced laterally from each other and said axis, one being on either side thereof, and located above and generally parallel to the support plane of the base, said first lever arms each having an elongated handle and a portion located and formed for engagement with a first portion of an object supported on the base upon pivoting of the lever arm about its axis toward said object, both first lever arms thereby coacting to flatten said first portion of the object; and two second lever arms mounted on the base, generally adjacent the center of the minor axis of the base, for pivotal movement about two axes oriented generally parallel to the minor axis of the base and perpendicular to the pivotal axes of the first lever arms, spaced laterally from each other and said minor axis, one being on either side thereof, and located above and generally parallel to the support plane of the base, said second lever arms each having an elongated handle and a portion located and formed for engagement with one of two second portions of an object supported on the base upon pivoting of the lever arm about its axis toward said object, said second lever arms thereby acting to flatten said second portions of the object.
Claim 7
Independent Claim
297 words
A device for crushing objects, such as individual metal cans, comprising a base for supporting an object to be crushed, the base having a major and a minor axis and at least one member defining a support plane of the base against which the object is to be crushed; two first lever arms mounted on the base, generally adjacent to the center of the major axis of the base, for pivotal movement about two axes oriented generally parallel to the major axis of the base, spaced laterally from each other and said axis, one being on either side thereof, and located above and generally parallel to the support plane of the base, said first lever arms each having an elongated handle and a portion located and formed for engagement with a first portion of an object supported on the base upon pivoting of the lever arm about its axis toward said object, both first lever arms thereby coacting to flatten said first portion of the object; and two second lever arms mounted on the base, generally adjacent the center of the minor axis of the base, for pivotal movement about two axes oriented generally parallel to the minor axis of the base and perpendicular to the pivotal axes of the first lever arms, spaced laterally from each other and said minor axis, one being on either side thereof, and located above and generally parallel to the support plane of the base, said second lever arms each having an elongated handle and a portion located and formed for engagement with one of two second portions of an object supported on the base upon pivoting of the lever arm about its axis toward said object, said second lever arms thereby acting to flatten said second portions of the object.
Claim 8
Dependent Claim
72 words
A device according to claim 5 wherein the base and the lever arms are formed and dimensioned to support and crush cylindrical cans and wherein the two first lever arms are located in corresponding positions generally adjacent opposite portions of the cylindrical walls of a can supported on the base, the lever arms being positioned and configured such that the object-engaging portions thereof coact to flatten a center portion of the can.
Claim 9
Dependent Claim
60 words
A device according to claim 6 wherein the two second lever arms are located in corresponding positions generally adjacent the opposite ends of a can, supported on the base, each second lever arm being positioned and configured such that the object-engaging portion thereof engages and flattens the end wall of the can immediately adjacent to the said second lever arm.
Claim 10
Dependent Claim
34 words
