ABSTRACT:
A timed telephone silencer with its associated features is disclosed, its intended use being for selectively disabling (silencing) a telephone for a user-determined interval during a time period when the user does not wish to be disturbed by telephone calls. The device provides a cord with attached modular plug for connecting the device to a telephone line, and a cord with modular jack for connecting a telephone to the device. A quartz-controlled clock provides the timing function, with a selector knob on the top external surface of the housing for choosing the number of hours that one wishes to have his telephone remain silent. The same knob can be used to instantly abort a period of telephone silence, or make the telephone operational for a few moments or minutes and then return to the period of telephone silence. The user can see by a glance at the device whether his telephone is in the on or off mode, this possible because of indicator lights on the device. At the end of the user-determined period of telephone silence, the device automatically returns an attached telephone to full function. The device operates on 110 VAC power.
