Apparatus for crushing articles

An apparatus for crushing an article having a generally cylindrical side wall and a pair of opposed end walls, comprising a supporting frame, a fixed anvil mounted on the frame, a ram spaced from the anvil to provide a crushing zone therebetween and movable in a direction toward and away from said anvil to crush an article in the crushing zone, a chute to contain an article and having a lower end communicating with said crushing zone, feeding means for feeding an article from the chute to the crushing zone, drive means for moving the ram in a direction toward said anvil to crush the article in the crushing zone and for moving the ram in a direction away from said anvil, contacting means connected to the ram and projecting outwardly from the ram toward said anvil, said contacting means disposed to initially engage the side wall of the article prior to engagement of said article by said ram, biasing means for biasing said contacting means outwardly from said ram in a direction toward said anvil, said contacting means being moved inwardly against the force of said biasing means as said article is crushed by said ram, and stripping means disposed in the crushing zone and disposed to be engaged by a crushed article to prevent said article from adhering to said ram as the ram moves in the direction away from said anvil, said stripping means being mounted in fixed relation to said supporting frame and being mounted for movement in an opening in said ram.

An apparatus for crushing articles, comprising a frame, a fixed anvil mounted on the frame, a ram mounted for movement on the frame in a direction toward and away from said anvil to crush an article located in a rushing zone between said anvil and said ram, drive means for moving said ram in a direction toward and away from said anvil, chute means to support a stack of articles in end-to-end relation, said stack including a lowermost article and a second lowermost article, stack control means engaged with the second lowermost article in the stack and movable between an engaging position where said stack control means engages said second lowermost article and a release position, retaining means disposed in said chute means beneath said stack control means and disposed to support the lowermost article in the stack, said retaining means movable between an article supporting position and a release position, means responsive to movement of the ram in a direction away from said anvil for moving said retaining means to the release position, means responsive to movement of the ram in a direction away from said anvil for moving said stack control means to the engaging position, means responsive to movement of the ramp in a direction toward the anvil for moving said stack control means to the release position, article support means disposed at the lower end of said crushing zone and mounted for movement between an article supporting position and a release position, and means responsive to movement of said ram in a direction away from said anvil for moving said article supporting means to the release position to thereby enable a crushed article to be discharged from said crushing zone.
