Abstract

Abstract This disclosure relates to a bone holding mechanism for supporting a bone by one end thereof while meat stripping operations are performed. In one of its embodiments, the invention relates to an apparatus which holds the tibia bone with the meat thereon while removing the fibula bone prior to the meat stripping operation. In another embodiment of the invention, the mechanism holds the tibia bone while the entire meat is being stripped. In each embodiment, the bone holding mechanism comprises a pair of cam-controlled, resiliently biased, movable jaws. In response to insertion of a bone, a triggering mechanism allows the jaws to move toward each other to hold the bone from rotational and longitudinal movement. In a more specific aspect of the latter embodiment, a sliding gate, in response to the triggering mechanism, is moved into a position adjacent to the ends of and surrounding the jaws to hold the bone from movement while deboning operations are performed. At the completion of the deboning operation, the jaws are released, and the bone is released from the holder.
