Abstract
Abstract This disclosure relates to a method and apparatus for breaking and extracting the keel bone from various types of dressed poultry carcasses. The apparatus includes an air cylinder having a pressure foot attached to the end of the air cylinder piston rod, and an anvil for supporting a poultry carcass. The anvil has a slot which is to be positioned under the keel bone of the carcass being processed. The pressure foot is used to force the keel bone into the anvil slot and cooperate with the side of the anvil to break the keel bone from the carcass. An extractor cup on the end of the anvil severs the keel bone from the carcass as the carcass is removed from the anvil.

An apparatus for processing a small eviscerated fowl by breaking the keel bone from the carcass and removing the keel bone from the carcass cavity comprising: a. a support frame having a vertical leg and a horizontal leg secured to the upper end of said vertical leg; b. a pneumatic cylinder having a reciprocating plunger, said cylinder being carried on said horizontal leg so that said plunger reciprocates in a vertical direction; c. a pressure foot carried on said plunger, said pressure foot having a concave surface conforming generally to the shape of the keel bone of the carcass being processed; d. an anvil for supporting said carcass during processing and stripping said keel bone from the carcass as said carcass is removed from said anvil, said anvil being secured at one end to said vertical leg and being located below and parallel to said horizontal leg, the other end of said anvil having spaced, parallEl side members which define a passage through said anvil below said reciprocating plunger, said anvil terminating in a cup-shaped portion secured to said side members, said cupshaped portion having shoulders which extend above the upper edges of said side members, said pressure foot on said plunger being adapted to strike said carcass supported on said anvil and cooperate with the upper edges of said side members to break the ribs and cartilage attached to said keel bone and force said keel bone into said passage as said pressure foot is momentarily inserted into said passage when said plunger is reciprocated, said cup-shaped portion of said anvil engaging the keel bone upon removal of said carcass from said anvil, whereby said keel bone is stripped from said carcass and passes through said passage in said anvil; e. pneumatic control means for operating said pneumatic cylinder so that the pressure exerted on said carcass is quickly applied and released; and f. means for actuating said pneumatic control means.
