  • Patent number: 5449268
    Abstract: A variable speed drive mechanism for transferring a workpiece in an accelerated and decelerated motion comprising a pair of spaced carrier arms driven by a main shaft that rotates through a fixed stationary gear. A set of pulleys is mounted between the carrier arms and a flexible drive member drivingly connects the stationary gear and the pulleys. One of the set of pulleys drives a pair of bellcranks each of which is operatively connected to a transfer arm through a roller and cam slot arrangement. The connection between the bellcrank and the transfer arm provides a more desirable acceleration and deceleration movement of the transfer arms.
