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.
Claims13
A telephone handset lifting device comprising:
- an electromagnetic coil;
- shaft means formed to extend vertically through said electromagnetic coil, and horizontally across said coil;
- said shaft means being vertically moveable by said electromagnetic coil;
- structure for supporting said coil and said shaft means;
- the end of said horizontally extending shaft means being formed to support a telephone handset for raising and lowering said telephone handset;
- an electric current circuit connected to said coil for energizing said coil;
- switch means in said electric current circuit operable to open and close said circuit;
- a time sequence means for operating said switch means;
- and
- a plurality of manually operable elements on said time sequence means arranged thereon to preselect a plurality of irregular time sequences for operating said switch means repeatedly during a time cycle.
