ABSTRACT:
An intermittent motion device which converts input continuous motion into precisely timed output interrupted intermittent motion. In a generic preferred embodiment the device comprises a primary driver and a secondary driver that are attached to an input shaft, and a two-sided indexing driven wheel attached to an output shaft. The primary driver engages one of four drive slots on the primary side of the driven wheel, and rotates the driven wheel 72.degree. each time the input shaft makes one revolution. The secondary driver engages the one slot on the secondary side of the driven wheel, and rotates the driven wheel 72.degree. every fourth revolution of the input shaft. The indexing driven wheel is locked in a stationary dwell position between indexes by locking rollers on the driven wheel that engage in locking grooves in the primary and secondary driver wheels. Unlike the prior art this device is compact, eliminates intermediate drive shafts, and the novel two-sided structure of the indexing driven wheel makes a great variety of resultant output motions possible.
