  • Patent number: 4234997
    Abstract: A body of a butchered animal suspended at its hind legs by suspension conveying means is conveyed by means of a conveying table to a station for splitting the body into two halves along the spine, where the body and the conveying table become stationary and the body is turned through 90 degrees in a splitting position between body supporting means and pusher means which is indexed with the conveying table, so that the back of the body will face the body supporting means. Then, sensing means senses the presence of the body in the splitting position and actuates the body supporting means to bring it to an operative position to support the body, while the pusher means is also actuated to urge push rods extending through the conveying table into contact with the body to clamp it tightly to the body supporting means.
