Abstract

22,696. Whitney, S. S. Oct. 20. Massage.-An alternating-current motor for operating a massage instrument H comprises a pair of electromagnets between which oscillates a polarized armature carried by a spring. In the construction shown, a casing A is provided with a handle D<1> and a revoluble dome or cover B, the operative parts being attached to the dome for adjustment and removal. A pair of electromagnets E<2> is secured to a U -shaped frame E fixed to the dome, and is supplied with alternating current, a switch such as d' being fixed in the handle. A soft-iron armature G is carried by a spring G' secured to the dome B, the spring being tuned to vibrate synchronously with the alternations of the current. The armature, which is polarized by a pair of permanent magnets M, is provided with a socket g<1> in which the instrument H is fitted.
