  • Patent number: 5306202
    Abstract: One known type of machine in use for separating meat from feed material containing sinew-like material and bone particles includes a foraminous cylinder or sleevelike screen in which a conveying auger rotates. Such feed material is introduced into the infeed end of the cylinder/auger combination. The auger conveys the feed material toward the discharge end of the combination. During conveyance, meat is separated by exuding through the foramina. Compacted residue formed primarily of bone particles and sinew-like material discharges through a restricted orifice provided by a valve located at the discharge end of the cylinder/auger combination. Heretofore, the foramina in the screen were arranged in circumferential rows separated from each other by circumferential bands free of foramina. According to the present invention, novel foraminous cylinders or screens are provided in which the foraminous areas do not include circumferential bands which are free of foramina.

  • Patent number: 5064403
    Abstract: Apparatus for removing meat from the drumsticks of poultry, such as turkeys and chickens, utilizes aligned, tandem cylinders, the first of which urges the second along a guided path, the second carrying a centering cone pusher thereon for receiving the meat end of the drumstick axially thereinto. Transversely moving gates engage the drumstick about the hock knuckle end and the centering cone, upon moving forward under the force exerted by the first cylinder against the second cylinder, pushes the hock knuckle end through and past the closed gates. This places extreme tension on the tendons between the gates and where they are attached to the hock knuckle, causing the tendons to break while the meat is formed into a gatered mass in and adjacent the centering cone. The gates are withdrawn and the second cylinder is activated, causing a rod to project axially through the meat mass and against the meat end of the bone, urging the bone through a guide passageway and normally expelling it from the apparatus.
