Abstract
Abstract An apparatus for crushing and flattening cans or other receptacles comprising, a pair of crushing plates between which cans to be crushed and flattened are caused to become positioned, one of the crushing plates being a vertical and stationary one, the other plate being angularly disposed and having bodily slidable movement relatively to the fixed crushing plate. Means are provided for slidably moving the movable crushing plate to and from the stationary crushing plate so that cans entering between the plates receive intermittent pressure and release to be crushed and flattened. Opposing faces of the crushing plates may be serrated or otherwise roughened for non-slip engagement with the cans.

Claims Analysis
Total Claims: 4
Claim 1
Independent Claim
159 words
An apparatus for crushing and flattening cans or similar articles comprising, a pair of spaced channel bars, plates disposed on top of said bars and serving to hold the bars coupled together in spaced, parallel relation, one of the plates supporting a vertically-disposed and fixed crushing plate, a slide movable along the top of the bars between the plates, said slide carrying a crushing plate that is fixed and non-pivotal with respect to the slide, said slide-borne plate being disposed at an angle with respect to the fixed crushing plate, said slideborne plate maintaining constant angularity with respect to the fixed plate during the sliding movement of the slide, a driven shaft, eccentric means disposed between said shaft and the slideborne plate to impart a reciprocating movement to the slide and slidably and non-pivotally move its plate to and from the fixed crushing plate to thereby alternately impart and release pressure on cans that enter between the curshing plates.

Claim 3
Independent Claim
195 words
An apparatus for crushing and flattening cans and similar articles comprising, a pair of spaced channel bars, plates disposed on top of said bars in spaced relation, one of the plates supporting a fixed, vertically-disposed crushing plate, a slide movable along the top of the bars in the space between the plates, said slide carrying a movable, non-pivotal crushing plate having a crushing surface disposed at a constant and uniform inclination with respect to the face of the fixed crushing plate, said movable plate being fixed in reference to the slide so that it maintains constant inclination and angularity in respect to the fixed crushing plate during its sliding movement to and from the fixed crushing plate and during the crushing operation, a driven shaft, eccentric means disposed between said shaft and the movable crushing plate to impart a reciprocating movement to the movable crushing plate and slidably and non-pivotally move it to and from the fixed crushing plate to thereby alternately impart and release pressure on the cans that enter between the crushing plates, the movable plate being reinforced by gussets, which gussets serve as bearing supports for one end of the driven shaft.
