Abstract
An apparatus for deboning a chicken leg includes a conveyor for holding the leg by the hock, a plunge knife device for severing the knee joint and pulling the femur from the thigh meat, a cutting device for severing the tendons at the hock of the leg, and a scraper for pulling the drumstick meat along the tibia and fibia toward the knee. The scraping mechanism includes a laterally movable carriage supporting at least one pair of jaws having notches along their edges to clear the leg bones, a first air cylinder for closing and opening the jaws, and a second air cylinder for moving the carriage away from the hock-restraining conveyor.
