Patent number: 4467501Abstract: An improved apparatus for centrifugally extracting crabmeat from crabs provides a frame which supports a driven rotary shaft mounted thereon. A first annular plate is mounted for rotation on the shaft and driven thereby. A plurality of closely spaced wire support members radiate from the first plate and have a common path of rotation when the plate is rotated by the drive shaft. A second annular plate is movably mounted upon the frame with respect to the first plate between "loading" and "spinning" positions. A plurality of closely spaced, radially positioned, pointed spikes depend from the second plate and are positioned to intersect the path of rotation of the wire support members in the "spinning," the spikes being spaced from the path in the loading position. A lifting mechanism moves the second plate vertically between the "spinning" and "loading" positions.Type: GrantFiled: February 10, 1983Date of Patent: August 28, 1984Assignee: Alfred R.

Patent number: 4104764Abstract: A crab claw processing machine for cutting and removal of the shell comprising a machine body having a rotating table mounted thereon. The rotating table has a plurality of rotary claw holders provided with individual drive sprockets mounted at its peripheral edge portion, each rotary claw holder being capable of holding a crab claw to be processed. As the rotating table is spun by a power source, such as an electric motor, the sprockets of each peripherally placed rotary claw holder engage a fixed drive chain which spins the respective sprocket rotary claw holder, and the crab claw contained therein. Each rotary claw holder and its contained crab claw are sequentially brought in to proximity with a high-speed rotating saw capable of cutting the claw. The saw can be provided with a gauge for controlling the depth of the cut.Type: GrantFiled: November 26, 1976Date of Patent: August 8, 1978Inventor: John B. Coast
