Abstract
A cam drive system having parallel input and output shafts and means for rotating the input shaft includes a plurality of cams coupled at intervals around the periphery of the input shaft. Each cam utilizes a camming surface which incorporates a radially outwardly sweeping step section and a constant radius dwell section positioned adjacent to each step section. A plurality of cam followers are coupled at intervals around the periphery of the output shaft. Each cam follower is aligned to engage a single one of the cams. The present invention converts the continuous rotation of the input shaft into intermittant displacements of the output shaft.
