Abstract
29,310. Loebl, A. Dec. 31. Electric dumb-bells; electric excercising-apparatus. -Dumb-bells and the handles of other exercising- apparatus are fitted with means for supplying an alternating electric current to the user. The shell A<1>, Fig. 1, of a dumb-bell has screwed into it an end-piece A<2>, within which is a dry cell B kept in place by springs C, C<1> connected to the positive and negative terminals of the cell. In the other end of the bell is an induction coil E, insulated from the bell. The primary circuit of the induction coil is completed from the spring C<1> by a metal yoke N insulated by a plate D, and an interrupter K is connected to one primary terminal of the coil E, the other terminal being connected to a switch J, Figs. 1 and 2, fixed to a non- conducting board F. The switch Jin its operative position is connected to the shell A' of the bell, which is electrically connected by means of the springs C to the cell B. One secondary of the induction coil is connected through the switch J to the dumb-bell, and the other is connected to a second dumb-bell by means of a wire L attached by a plug M and socket M<1> to a screw stud G connected to the board F. A cap A<3> is secured in place over the end of the bell by a nut H and an insulating-washer I. The intensity of the secondary current can be regulated by the adjustment of the position of a core P, guided by the yoke N and provided with a stud Q which passes through a slot in the bell and by means of which the core can be moved.
