ABSTRACT:
The disclosed massager comprises a frame at the top portion of which are a plurality of beaters or massaging elements arranged as side-by-side mirror-image systems driven by parallel camshafts, and the beaters are controlled through combination motions by guide members, one for each system, by which the beaters are guided via lost-motion means on the guide members. A third camshaft centrally between the beater-drive camshafts functions to reciprocate the guide members to further augment the motions of the beaters. The cams on each beater camshaft are strategically timed so that each beater moves in a phase different from its neighbors. The beater camshafts are driven at a speed faster than that of the guide member camshaft.
