Abstract: Poultry thighs are disjointed by the relative movement of members which contact the breast side of the thigh joint area and members which contact the back side of the thigh joint area. The members are arranged in pairs so that two members on the back side of the bird are moved simultaneously toward a corresponding pair of members on the breast side of the bird. One pair of members is fixed to a rotating support, and the other pair of members is mounted on a cam-actuated arm which is pivotally mounted on the rotating support. A plurality of corresponding pairs of members is provided around the circumference of the apparatus.

Abstract: Device for removing fat from slaughtered poultry, provided with a screw spindle drivable around its longitudinal axis, said spindle being rotatably mounted in a cylindrical sleeve surrounding at least a part of the screw thread on the spindle with a radial clearance. Machine with devices for removing fat from slaughtered poultry mounted in the shape of a roundabout.

Abstract: Device for cutting open the bottom of slaughtered poultry, provided with a knife which is movable along an arc of a circle by means of a follower cooperating with a curved path. According to the invention at least part of the cutting edge of the knife is at least substantially vertical at the beginning of the operative stroke and substantially horizontal at the end of the operative stroke and the said part of the cutting edge of the knife in the operative direction of movement thereof is trailing with respect to the foremost outermost point of the cutting in that direction.

Abstract: A stretching mechanism of a device for cutting slaughtered poultry, said mechanism being provided with a support surface for the bird, with means to hang the bird by the legs, with means to hold the wings of the bird and with means to hold the trunk on the support surface, said trunk holding means including gripper means which engage the spine of the bird. According to the invention the gripper means consist of a symmetrical centering fork and that the centering fork and the support section are guided movably in two directions relative to each other in a plane, perpendicularly to the support surface, wherein in the operative end position the centering fork engages the spine at the inside of the trunk of the bird.

Abstract: A mechanism for holding slaughtered birds in a poultry cutting machine has a support member for engaging and supporting the bird, and rump engaging members which are spaced inwardly of the legs of a bird. The rump engaging members are movable in a forward direction relative to the bird to press the bottom of the bird in a forward direction while a knife cuts the legs from the rumps.

Abstract: The invention relates to a device for drawing the crop and gullet from slaughtered poultry, provided with a bore tube, having loosening and entrailing means at its free end, and which is introduced into the bird's trunk via an opening between the breast-bone and the tail of the bird. According to the invention two diametrically opposed strips (42, 43) are secured at the free end of the bore tube (14) and extend parallely to the center line of the tube, said strips along two diagonally opposed edges being provided with teeth (44) which are directed obliquely inwardly and toward the free end of the strip (42, 43).

Abstract: A device for cutting slaughtered poultry in separate pieces. A bird is held by at least one radial processing device which is movable on a frame by a driving device which is provided with a processing arm, at the side facing the frame being provided with an adjustment mechanism which can reorient the processing device during the movement of the arm in a number of various positions of rotation with respect to the arm and a blocking mechanism which can fix the processing device in said positions of rotation, with a deblocking mechanism for unlocking the processing device, and said processing arm at the side facing away from the frame being provided with a stretching mechanism for holding the bird.
