ABSTRACT:
A worktool transfer apparatus for moving a worktool along a recirculating path includes a chain moveably supported by two spaced sprockets of equal diameter. A motor rotates one of the sprockets to cause circulating movement of the chain. A constant breadth velocity cam is fixedly attached to one of the chain links so that the rotational center of the velocity cam is aligned with the rotational centers of each of the sprockets as the link to which the velocity cam is attached moves about the periphery of each sprocket. Four rollers extend from the cam and ride along an oval track for maintaining orientation of the velocity cam as it moves with the chain. A cross bearing block is moved linearly back and forth by the velocity cam. A worktool is attached to and moves with the cross bearing block and is independently moveable laterally of the cross bearing block.
