Abstract

226.971. Hadley, C. A., and Rose Street Foundry & Engineering Co., Ltd. Dec. 27, 1923. Heating by electricity.-A resistance welding machine having a primary winding 8 supplied with current from an alternator 7 is provided with an auxiliary circuit opened and closed sim. ultaneously or in close sequence with the main switch 4, the auxiliary circuit when closed reducing the resistance in the circuit of the field windings f of the alternator. The main-switch 4 and a switch in the auxiliary circuit are operated by the treadle mechanism operating the upper electrode. Closure of the switch f shorts part of a resistance h fitted in series with the field windings f.
