Abstract

10,119. Newbery, G. M., and British, Prometheus Co. May 1. Signals, electric.-The current supplied to each section of a multiple-circuit electric cooking and beating apparatus is controlled by a switch having an additional contact for passing current to a pilot lamp or other indicating-device so as to give a signal simultaneously with the bridging of the main contacts of any section. In the diagram of connexions shown in Fig. 1, two resistance sections r<1>, r<2> are shown connected at one end with the negative main n. Their other ends are shown connected respectively to two contacts t<2> on switches s<1>, s<2>. Simultaneously with the bridging of contacts t<1>, t<2> to close a heating-circuit, the live part of the switch is connected to a third contact t<3>, causing a pilot lamp L or other indicating- device to be switched in.
