Title: Improvements relating to telephone systems
IPC: H04M3/54
Filed: 1947-11-26
Abstract: 635,644. Extension circuits. SIEMENS BROS. & CO., Ltd., and HUMPHRIES, H. E. Nov. 26, 1947, No. 31271. [Class 40 (iv)] The user of an extension telephone is enabled, by means of extension control equipment, to filter when required calls for the user of the main telephone, the apparatus being such that " main may set up calls in the usual way when the exchange line is free or may take a call offered by " extension " merely by lifting his receiver or handset. Conversations between " extension " and " main " are not transmitted over the exchange line and " extension " cannot listen to conversations between " main " and other parties. In the embodiment shown in the drawing, " main " brings the extension control apparatus CON into use by operating a key EX which connects in relay C in place of the bell BE and provides a battery connection. On receipt of ringing current from an incoming call, relay C operates on winding (I) and holds on winding (II). Relay CA operates on its winding (I), completes a circuit for its holding winding (II) and lamps BS and ENG, disables at ca7 the subscriber's keysender if one is fitted, and switches the exchange line LX to the extension wires LE. When " extension " answers, a switch-hook SH completes a circuit for relay S which releases relay C. " Extension may offer the call to "main" by operating a key OF to energize relays C and H, which latter completes a local conversational circuit between the main and extension telephones isolated from the exchange line LX which has a holding loop RH connected across it. Relay S releases slowly while relay B by self-interruption gives an audible signal to " main," who.lifts his receiver. " Extension " switches the call to " main " by first releasing key OF to release relay C followed by H and hence to energize S, and then closing a key SW to short-circuit the holding winding (II) of relay CA, which releases and switches the exchange line LX to the main telephone wires LM while also releasing S. " Main " can give " extension the exchange line by asking " extension " to lift his receiver and then momentarily operating a key TR which energizes relay B followed by the line switching relay CA. The exchange line may be switched through to " extension," for example when " main " is absent, by means of the two changeover contacts of a switch OU.
