Abstract

A telephone silencing system is provided for use with at least one telephone receiver and an external telephone line electrically connected with the telephone receiver. This system includes a switch electrically connected in series between the telephone line and the telephone receiver. The switch is actuatable between a closed position, in which the telephone receiver(s) is connected to the telephone line, and an open position, in which the telephone receiver(s) is electrically disconnected with the telephone line. A receiver is operatively connected with the switch actuated between a closed and open position in response to a preset signal. A transmitter, in turn, when actuated, generates the preset signal to the receiver to thereby actuate the switch between its closed and open position.

Claims

1. A telephone silencing system for use with a plurality of remotely located telephone receivers and an external telephone line electrically connected with each of said telephone receivers, the system comprising:

an electronic switch electrically connected in series between the telephone line and each of said telephone receivers, said switch being actuatable between a closed position in which said telephone line is electrically connected with said telephone receivers and an open position in which said telephone line is electrically disconnected from said telephone receivers,

a radio receiver responsive to a preset signal to generate a predetermined output signal,

means responsive to said predetermined output signal to actuate said switch from one of said closed and said open positions to the other of said closed and open positions,

a radio transmitter remotely operable from said radio receiver for generating said preset signal, and

a light in said radio transmitter which is illuminated when said switch is in said open position.

2. The invention as defined in claim 1 and comprising timer means connected to said actuating means for resetting said switch to said closed position after a predetermined time period following actuation of said switch from said closed to said open position.
