Abstract
Abstract An upstanding abutment wall outwardly from a first side of which a horizontal support extends. A vertical slot extends along the wall and projects at least slightly outwardly from the first side thereof for downwardly receiving therethrough a can extending lengthwise along the first side of the wall and flattened thereagainst. A pressure plate generally paralleling and opposing the first side of the wall is provided and guidingly supported for reciprocation toward and away from the wall for flattening a can thereagainst and the horizontal support includes a pair of bowed leaf springs disposed generally normal to and outwardly of the first side of the wall, supported at their ends remote from the wall and curving upwardly at their ends adjacent the wall for support of an unflattened can therefrom in elevated position relative to the slot, outwardly of which slot the ends of the springs adjacent the slot terminate.

350 words
An upstanding stationary abutment surface, an upstanding pressure plate generally paralleling and opposing said abutment surface and guidingly supported for movement toward and away from the abutment surface, means operatively associated with said pressure plate for alternately shifting said pressure plate toward and away from said abutment surface, means for automatically positioning a container to be compressed between said plate and said abutment surface each time said plate is shifted away from said abutment surface, and means for automatically discharging a container compressed between said pressure plate and abutment surface upon initial movement of said pressure plate away from said abutment surface, a pair of upstanding walls, said pressure plate and abutment surface being disposed in upstanding planes generally normal to said walls, said pressure plate being disposed between the movable along said walls, said abutment surface comprising the surface of an end wall extending between one pair of corresponding ends of the first mentioned walls opposing said pressure plate, a lower wall extending between the lower marginal edge portions of said end wall and parallel walls, said means for discharging a compressed can comprising a slot formed in said lower wall and extending along and projecting outwardly from the lower marginal edge portion of said abutment surface, said means for automatically positioning a can between said pressure plate and abutment surface including an inclined chute whose lower end is registered with upper portion of the area defined between said pressure plate and abutment surface when said pressure plate is shifted away from said abutment surface, and also retractable spring means including portions thereof disposed between the lower portions of said pressure plate and abutment surface when said pressure plate is retracted away from said abutment surface and operable to support a can disposed between said pressure plate and abutment surface in elevated position above the lower extremities of said pressure plate and abutment surface, said spring portions being disposed to be automatically cammed downwardly by said pressure plate and thus retracted from between said pressure plate and abutment surface upon movement of said pressure plate toward said abutment surface.
Claim 2
Dependent Claim
350 words
An upstanding stationary abutment surface, an upstanding pressure plate generally paralleling and opposing said abutment surface and guidingly supported for movement toward and away from the abutment surface, means operatively associated with said pressure plate for alternately shifting said pressure plate toward and away from said abutment surface, means for automatically positioning a container to be compressed between said plate and said abutment surface each time said plate is shifted away from said abutment surface, and means for automatically discharging a container compressed between said pressure plate and abutment surface upon initial movement of said pressure plate away from said abutment surface, a pair of upstanding walls, said pressure plate and abutment surface being disposed in upstanding planes generally normal to said walls, said pressure plate being disposed between the movable along said walls, said abutment surface comprising the surface of an end wall extending between one pair of corresponding ends of the first mentioned walls opposing said pressure plate, a lower wall extending between the lower marginal edge portions of said end wall and parallel walls, said means for discharging a compressed can comprising a slot formed in said lower wall and extending along and projecting outwardly from the lower marginal edge portion of said abutment surface, said means for automatically positioning a can between said pressure plate and abutment surface including an inclined chute whose lower end is registered with upper portion of the area defined between said pressure plate and abutment surface when said pressure plate is shifted away from said abutment surface, and also retractable spring means including portions thereof disposed between the lower portions of said pressure plate and abutment surface when said pressure plate is retracted away from said abutment surface and operable to support a can disposed between said pressure plate and abutment surface in elevated position above the lower extremities of said pressure plate and abutment surface, said spring portions being disposed to be automatically cammed downwardly by said pressure plate and thus retracted from between said pressure plate and abutment surface upon movement of said pressure plate toward said abutment surface.
Claim 3
Dependent Claim
311 words
A stationary horizontal base plate, an upstanding stationary abutment member supported from and projecting upwardly beyond said base plate, said base plate having a narrow slot formed therein extending along one side of said abutment member and downwardly through which a flattened item sliding downwardly along said one side of said abutment member may pass, elongated bowed leaf spring means overlying said base plate on the side of said slot remote from said abutment member and extending lengthwise toward and away from the latter with the end of said leaf spring means remote from said abutment member anchored relative to said base plate and the other free end of said leaf spring means adjacent said slot curving upwardly away from said baSe plate and terminating a space distance from said abutment member and the remote side of said slot when said spring means is in a substantially horizontal straightened condition, and an upstanding pressure plate opposing said abutment member guidingly supported for movement relative to said base plate toward and away from said abutment member with said pressure plate overlying said leaf spring means and operable to downwardly deflect and thus retract said free end of said leaf spring means upon movement of said pressure plate toward said abutment member, the free end of said leaf spring means, when said pressure plate is retracted away from said abutment member, curving upwardly into the lower portion of the area disposed between said pressure plate and said abutment member for supporting a can to be flattened between said pressure plate and said abutment member in an elevated position above the lower extremity of said area until initial movement of said pressure plate toward said abutment member causes the can to be flattened to be frictionally gripped and thus retained in elevated position above the base plate between the pressure plate and abutment member.
Claim 4
Dependent Claim
311 words
A stationary horizontal base plate, an upstanding stationary abutment member supported from and projecting upwardly beyond said base plate, said base plate having a narrow slot formed therein extending along one side of said abutment member and downwardly through which a flattened item sliding downwardly along said one side of said abutment member may pass, elongated bowed leaf spring means overlying said base plate on the side of said slot remote from said abutment member and extending lengthwise toward and away from the latter with the end of said leaf spring means remote from said abutment member anchored relative to said base plate and the other free end of said leaf spring means adjacent said slot curving upwardly away from said baSe plate and terminating a space distance from said abutment member and the remote side of said slot when said spring means is in a substantially horizontal straightened condition, and an upstanding pressure plate opposing said abutment member guidingly supported for movement relative to said base plate toward and away from said abutment member with said pressure plate overlying said leaf spring means and operable to downwardly deflect and thus retract said free end of said leaf spring means upon movement of said pressure plate toward said abutment member, the free end of said leaf spring means, when said pressure plate is retracted away from said abutment member, curving upwardly into the lower portion of the area disposed between said pressure plate and said abutment member for supporting a can to be flattened between said pressure plate and said abutment member in an elevated position above the lower extremity of said area until initial movement of said pressure plate toward said abutment member causes the can to be flattened to be frictionally gripped and thus retained in elevated position above the base plate between the pressure plate and abutment member.
