Abstract

813,653. Sub-station equipment. ROBOSONIC INDUSTRIES Inc. Oct. 29, 1956, No. 32991/56. Class 40 (4). In a phonographic device for answering and recording incoming calls, a microphone 32 and a loud-speaker 33 are acoustically coupled to the handset 24 and, on the arrival of an incoming call, the sound of the telephone bell is picked up by microphone 32 to set the device in operation by way of amplifier 42, neon lamp 39; photo-electric cell 44a, amplifier 45 and relays 46 and C ; the necessary switching operations are effected at predetermined times by two cam shafts 21 and 22 driven by motors 65 and 78 respectively. A solenoid 27 controls the cradle-switch and a bell 34 signals to the caller when to start and stop speaking. Previously recorded instructions to the caller are sent from turntable 52, and the caller's message is recorded on wire or tape 64. An authorized person may rewind and play back the wire or tape 64 by calling the sub-station and sending a code of sound and silence (operating and releasing relay C) to coincide with switching effected by the cam-shafts. If the correct code is not sent, motor 78 is reversed.
