• a crushing ram disposed within said housing and pivotable between an open position where said ram is adjacent said back wall and opposite said crushing wall, and a closed position where said ram is adjacent said crushing wall of said front wall, said crushing ram being pivotable about a pivot axis, which is rotatably supported by said two side walls, said ram including a crushing surface which is generally parallel to said front and back walls of said housing when said ram is in the closed position, said ram additionally including side plate mounted perpendicular to said crushing surface and generally parallel to said side walls;
• and
• a longitudinally extending handle rotatably mounted on said housing, and linkage means for coupling said handle to said ram, said linkage means comprising:
• (a) a cylindrical coupling attached to said handle and passing through one of said two side walls;
• (b) a plate having a first end attached to said cylindrical coupling and a second end;
• and
• (c) a link connector having a first end rotatably coupled to said ram and a second end rotatably coupled to said second end of said plate;
• a link axis rotatably mounted onto said side plates, said first end of said link connector being rotatably mounted on said link axis;
• a spring attached to said link axis and said back wall of said housing for biasing said ram in the open position, wherein said link axis is generally located in the middle of said ram;
• and
• whereas a can to be crushed is placed into the top opening and said handle is rotated to move said ram between the open and closed positions via said linkage means to crush the can against said interior crushing wall until it is sufficiently crushed, to be discharged through the bottom opening.
