Abstract
An indexing mechanism having a base and a cyclical drive unit mounted on the base and connected through a connecting member to a driven member which is supported on and for movement relative to the base. The connecting member has a coupling arrangement thereon which is movable into and out of engagement with the driven member. A control is provided for effecting a simultaneous (1) coupling by the coupling arrangement of the drive member to the driven member and (2) driving of the driven member by the drive member in one direction and a simultaneous uncoupling of the coupling arrangement to (1) uncouple the drive member from the driven member and (2) to drive the drive member in an opposite direction relative to the driven member. The coupling arrangement includes a slip clutch device and the coupling force of the slip clutch device is adjustable to provide a sufficient drive of the driven member but cause slippage to occur if resistance is encountered which prevents a movement of the driven member in response to the drive therefor.
