ABSTRACT:
This invention operates in combination with a cradle supported telephone handset. It includes an electric switch operated by a variable timer which is set to operate at various times of a period of absence and for lengths of time selected by the occupant of a dwelling prior to vacating or leaving his dwelling. The electric current which is controlled by the switch energizes an electromagnetic coil periodically as preselected on the timer. The energizing of the electromagnetic coil operates to lift a shaft the end of which is formed to support the telephone handset and by which means the telephone handset is lifted from its cradle position on the telephone to close the telephone switch and thereby render the telephone in operating condition producing a busy signal indicative of occupancy.
