Abstract
8006. Dobie, L. April 7. Electric dumb-bells ; massage.-In a pair of dumb-bells, one of the bells is formed of magnetized steel, within one end of which an armature, operated by a spring grip, is caused to rotate. The magnet c is bent up as shown, and is provided with a cover forming one part of the handle fixed to brass side-plates d on the circular ends of the dumb-bell. The other part a of the handle is supported by springs f, and works in guides in the side-plates. A. pinion i, on the axle of the armature, is rotated through suitable gearing by means of a rack m and pivoted lever n, operated by the spring-grip handle. The armature rotates in insulated bearings. The second dumb-bell is made like the first, but is not magnetized and has no armature. The two dumb-bells are electrically connected by means of a wire, attached to the axle of the second bell, and a spring attached to the end of the bell bears against the teeth of the driving-pinion so as to make and break circuit and so give shocks. The lever n, Fig. 1, and the gearing in connection with it, acts as a short circuit, and intensifies shocks. A spring may be adapted to bear against the teeth of the pinion i, so as to give shocks. In a modification, the rack m may engage directly with the pinion i. A massaging-roller or other apparatus may be used instead of the second dumb-bell.
