Abstract
152,304. Sinzig, F., and Wenger, H. Oct. 9, 1919, [Convention date]. Void [Published under Sect. 91 of the Act]. Heating systems.- Relates to means for connecting either one or both of two heating- circuits of an electric vulcanizing - apparatus or other consuming- device, separately or in series, to the supply and consists in connecting one end a<1>, b<2> of each heating &c. element A, B directly to two plugs f<1>, f<3> and connecting the other ends a<2>, b<1> to the common middle plug f<2> through a three-way switch C. When the plugs f<1>, f<2> are connected to the supply, the element A is in operation; when the plugs f<2>, f<3> are connected the element B is in operation, and when the outer plugs f<1>, f<3> are connected to a higher voltage supply both elements are in operation in series. In all cases the circuit passes through the switch C so that when the switch is brought to the off position, the heating-circuit is broken.
