Abstract
371,497. Hotel and like signalling devices. PHOENIX TELEPHONE & ELECTRIC WORKS, Ltd. and BELL, F. G., 38, Newman Street, Oxford Street, London. Feb. 3, 1931, No. 3461. [Classes 40 (i) and 118 (i).] Indicating ringing of bells to operators.-In a hotel or like signalling system wherein self-releasing call-pushes 3 operate distant signals, an indicator lamp 12 visible through the push is connected in a circuit which is completed by the depression of the push and broken by the depression of a re-setting push. The completion of the circuit is effected by a metal ring 8 on the sleeve 4 of the push bridging contacts 9.
