Claims Analysis
Total Claims: 3
Claim 1
Independent Claim
154 words
A soft drink can crusher, comprising in combination, a frame, a cylinder affixed on the frame, a piston slideable inside the cylinder, means for reciprocating said piston in said cylinder, an anvil at the end of said cylinder, said piston being forced by said means against a can placed in an end of said cylinder adjacent said anvil in further combination with means to cut said can in half, after the can has been crushed responsive to further piston reciprocation, wherein said piston is made of two piston members, each of which is aligned to bear against said can, and means whereby one said members is moveable to a position further advanced against said can than the other, wherein the anvil includes a portion moveable to a position out of alignment with said piston when it is moveable to said position further advanced, including means for moving said anvil portion responsive to piston reciprocation.
Claim 2
Dependent Claim

A soft drink can crusher, comprising in combination, a frame, a cylinder affixed on the frame, a piston slideable inside the cylinder, means for reciprocating said piston in said cylinder, an anvil at the end of said cylinder, said piston being forced by said means against a can placed in an end of said cylinder adjacent said anvil in further combination with means to cut said can in half, after the can has been crushed responsive to further piston reciprocation, wherein said piston is made of two piston members, each of which is aligned to bear against said can, and means whereby one said members is moveable to a position further advanced against said can than the other, wherein the anvil includes a portion moveable to a position out of alignment with said piston when it is moveable to said position further advanced, including means for moving said anvil portion responsive to piston reciprocation.
Claim 3
Dependent Claim
45 words
The combination of claim 1, wherein one of said piston members includes a linkage connected to the moveable anvil portion whereby reciprocation of the piston causes said linkage to move said anvil portion out of alignment when the piston is moved to the advanced position.
