Abstract

684,772. Substation equipment. BAKER, L. G. Jan. 24, 1951 [Jan. 24, 1950], No. 1891/50. Class 40 (iv). In a telephone call answering and message recording arrangement in which modification of the telephone set circuit is unnecessary, the telephone set hook switch is operated and the answering equipment is started by bell noise acting on a crystal microphone 15 in the answering equipment. The output from the microphone 15 is amplified to operate a thermal switch in the circuit of a solenoid 16, and an armature 17 lifts the handset in its cradle via arm 19 and receiver 20, whilst at the same time a motor 25 for driving the spools carrying the recording tape is started. Cams 29, 30 and 31 operate switches 32, 33 and 34 at predetermined times to energize a communication amplifier and control the reproducing and recording units respectively. Loud-speaker 37 in the cabinet conveys the reproduced message to the handset transmitter and a second loud-speaker 38 is used for reproducing messages recorded in the subscriber's absence.
