ABSTRACT:
An apparatus is disclosed herein for driving and selectively stopping a platform at predetermined work stations which includes a frame rotatably supporting the platform and a index wheel coupled to the platform in fixed relationship therewith. A drive wheel of lesser diameter is offset from the index wheel so as to overlap edge portions thereof and further includes a pin carried on its edge portion slidably engageable with one of a plurality of slots provided in the edge marginal region of the index wheel. The drive wheel is powered so that the pin enters and leaves each slot in a driving relationship whereby the index wheel and the platform are rotatably moved thereby. A spring biased dog operated by a cam mechanism selectively engages with the index wheel to register the platform at each of the respective work stations.
