  • Thigh deboner
    Patent number: 4639974
    Abstract: A plurality of wires (16a-16h) are each connected at one one to an oscillating ring 14, with the other ends of the wires connected to springs 18a-18h. When the ring 14 is rotated in one direction, the wires move closer to the longitudinal axis (28) of the ring. The bone of a poultry thigh is grasped by a grasping member (48) and is pulled through the polygon shape formed by the wires. The wires tend to wrap around the poultry bone (54), and as the bone is pulled between the wires, the wires strip the meat from the bone (FIGS. 7-12).
