Abstract
Abstract A compactor for salvaging aluminum cans has a removable upright tube that fits into a groove in the base; a replaceable anvil has an arcuate slot that fits over a section of the above-mentioned groove, and the tube wall passes through this slot to reach the groove. A thrust rod, bearing a crushing block, is hingedly connected to a lever arm by means of a U-bolt so that it can remain substantially upright.

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
178 words
A can compactor comprising, A. a base comprising walls defining a substantially horizontal groove in said base, B. an upwardly extending tube means, a. the bottom of said tube means removably fitting into and being restrained from lateral movement by said groove, b. opposite side wall portions of said tube means defining lever-arm-accepting slots, c. wall portions of said tube means defining a can-receiving opening, d. bottom wall portions of said tube means defining a can-ejection aperture, C. an upwardly extending fulcrum post fixedly supported on said base, D. fulcrum means, said fulcrum means being supported on said post, E. a lever arm, a. said lever arm being pivotally supported by said fulcrum means, b. said lever arm passing through and being upwardly and downwardly movable within said slots, F. a thrust member pivotally attached to said lever arm, said thrust member being movable within said tube means, G. a crushing block, said block being attached to the lower extremity of said thrust member thereby compacting cans placed within said tube upon the lowering of said lever arm.
Claim 2
Dependent Claim
