Abstract
Abstract A manually operated, wall-mountable, beverage can crusher having a compact hollow housing of rectangular cross-section, a ram mounted for sliding movement within the housing, and an ejection spring secured to the rear wall of the housing and operative to urge crushed cans forwardly out of the housing as the ram is raised. The ram is raised and lowered by means of a lever arm pivoted to the top of the housing and connected to the top of the ram through a thrust link pivoted at both ends. The lever arm includes a cover plate which completes closure of the housing when the arm is lowered, and also includes a channel section which partly surrounds the thrust link for compactness of construction.

Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
133 words
A manually operated beverage can crusher, comprising: an open-faced hollow rectangular housing mountable against a wall, and having a baseplate for supporting a can to be crushed; a ram mounted for sliding movement within said housing, including a pressure plate and two guide plates integral therewith and substantially perpendicular thereto for slidingly engaging interior walls of said housing; a lever arm mounted by one end to an upper portion of said housing; a thrust link pivotally connected to said pressure plate and pivotally connected to said lever arm at a point substantially below its point of pivotal mounting to said housing; and can ejection means including a leaf spring secured interiorly to said housing and operable to urge the can outwardly from said housing as said ram and said lever arm are raised.
Claim 2
Dependent Claim
133 words
A manually operated beverage can crusher, comprising: an open-faced hollow rectangular housing mountable against a wall, and having a baseplate for supporting a can to be crushed; a ram mounted for sliding movement within said housing, including a pressure plate and two guide plates integral therewith and substantially perpendicular thereto for slidingly engaging interior walls of said housing; a lever arm mounted by one end to an upper portion of said housing; a thrust link pivotally connected to said pressure plate and pivotally connected to said lever arm at a point substantially below its point of pivotal mounting to said housing; and can ejection means including a leaf spring secured interiorly to said housing and operable to urge the can outwardly from said housing as said ram and said lever arm are raised.
Claim 3
Dependent Claim
27 words
A beverage can crusher as set forth in claim 1, wherein said baseplate and said pressure plate are perforated to vent the can to be crushed therebetween.
Claim 4
Dependent Claim
35 words
A beverage can crusher as set forth in claim 1, wherein said lever arm includes a front cover plate for completing closure of said housing when said lever arm is lowered to its closed position.
Claim 5
Dependent Claim
125 words
A can crusher comprising: a hollow wall-mountable housing, including a baseplate for supporting a can to be crushed; a movable ram for crushing the can against said baseplate, mounted for sliding movement within said housing; a lever arm pivotally mounted on said housing; a thrust link pivotally connected to said ram and to said lever arm to transmit force to said ram on movement of said lever arm; and can ejection means operable as said ram is moved away from said baseplate, to eject the can from said housing; wherein said lever arm is in part of open channel construction and is sized to partly enclose said thrust link as said lever arm is lowered to a closed position, thereby providing a compact overall structure.
Claim 6
Dependent Claim
125 words
A can crusher comprising: a hollow wall-mountable housing, including a baseplate for supporting a can to be crushed; a movable ram for crushing the can against said baseplate, mounted for sliding movement within said housing; a lever arm pivotally mounted on said housing; a thrust link pivotally connected to said ram and to said lever arm to transmit force to said ram on movement of said lever arm; and can ejection means operable as said ram is moved away from said baseplate, to eject the can from said housing; wherein said lever arm is in part of open channel construction and is sized to partly enclose said thrust link as said lever arm is lowered to a closed position, thereby providing a compact overall structure.
Claim 7
Dependent Claim
