  • Patent number: 3962752
    Abstract: In general, the apparatus includes a plurality of crab holders attached like spokes on a wheel. At the first station the crab is loaded into one crab holder and during transit, the first crab passes two saws where the legs, claws and paddles are removed. The crab continues to move until it passes the second set of saws and the crab is sawed into three separate sections. When the crab is at the fourth station, these clamps automatically rearrange the crab into such a position that the cut faces are available to be picked. At this point the wheel ceases to turn and the pressure chamber including the escape heads advance over the exposed crab and a high pressure fluid such as water forces the meat from the crab into the escape tube. After the crab has been picked, the pressure chamber withdraws and the wheel again begins to move. The clamps are automatically opened and the empty shell ejected.
