Abstract
Abstract An apparatus for two-stage crushing of a can, the center of the can being first collapsed by a lever finger while the ends of the can are supported on shoulders at the sides of a swinging jaw on which the lever is fulcrumed, the ends of the can being tilted inwardly by such central collapse, and the tilted ends then being pushed against a fixed anvil to which the swinging jaw is hinged, resulting in the can being crushed flat between the jaw and the anvil.

Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
164 words
In a can crusher an anvil adapted to be fixed to a suPport; a swinging jaw having one side hinged to said anvil and an opposite side free to swing toward said anvil; said jaw having spaced seats for supporting at least one end of a can with the longitudinal axis thereof extending parallel to said jaw sides; and a lever pivoted to said free side of the jaw on an axis parallel thereto, said lever having at one end a finger extendible over said jaw and engageable with the can between its ends; and said lever having at its other end a handle operable to move said finger against the can to indent an intermediate portion of the can toward said jaw so as to collapse the can in a manner to tilt the ends of the can inwardly over said intermediate portion, and then to force said jaw toward said anvil so as to flatten the can ends against said intermediate portion.
Claim 2
Dependent Claim
164 words
In a can crusher an anvil adapted to be fixed to a suPport; a swinging jaw having one side hinged to said anvil and an opposite side free to swing toward said anvil; said jaw having spaced seats for supporting at least one end of a can with the longitudinal axis thereof extending parallel to said jaw sides; and a lever pivoted to said free side of the jaw on an axis parallel thereto, said lever having at one end a finger extendible over said jaw and engageable with the can between its ends; and said lever having at its other end a handle operable to move said finger against the can to indent an intermediate portion of the can toward said jaw so as to collapse the can in a manner to tilt the ends of the can inwardly over said intermediate portion, and then to force said jaw toward said anvil so as to flatten the can ends against said intermediate portion.
Claim 3
Dependent Claim
34 words
A can crusher as defined in claim 1: said jaw having shoulders adjacent its respective ends, in which said seats are each formed as a depression adapted to receive and position a can end.
Claim 4
Dependent Claim
27 words
A can crusher as defined in claim 2: said seats being of conic section form, increasing in width and depth toward the inner margins of said shoulders.
Claim 5
Dependent Claim
54 words
A can crusher as defined in claim 2: said jaw comprising a flat bottom having thickened ends providing said can support shoulders; said seats being arranged to position the can with its said intermediate portion supported above said bottom to allow the same to be bent downwardly under the indenting pressure of said finger.
Claim 6
Dependent Claim
41 words
A can crusher as defined in claim 4: said jaw having along its said sides, respective flanges one of which has its margin hinged to said anvil, and the other of which has, at its margin, means pivotally supporting said lever.
Claim 7
Dependent Claim
63 words
A can crusher as defined in claim 1: said anvil having means to attach it to a vertical support; and said jaw having its lower side hinged to the lower side of said anvil for swinging movement from a substantially horizontal position in which said seats face upwardly to receive a can, upwardly to an upstanding position in face-to-face adjacency to said anvil.
Claim 8
Dependent Claim
27 words
A can crusher as defined in claim 6: said jaw having means to abut said support so as to hold it in said substantially horizontal, can-receiving position.
Claim 9
Dependent Claim
31 words
A can crusher as defined in claim 1: said anvil having a medial vertical slot to receive said finger in a limit position of approach of the jaw toward said anvil.
