TIME-OPERATED LIGHT-SWITCH.
Specification of Letters Patent.
Patented Aug. 27, 1918.
Application filed July 23, 1917. Serial No. 182,258.
To all whom it may concern:
' Be it known that I, SWAN G. JOHNSON, a citizen of the United States residing at Los Angeles, in the county of liios Angeles and State of California, have invented new and useful Improvements in Time-Operated Light-Switches, of which the following is a specification.
An object of my invention is to provide means whereby a clock may operate an electric switch at a certain predetermined time to turn off lights or turn on lights, or control any other electrical device, such as a parlor heater, or water heater, or the like.
Another object of my invention is to make an actuator which may be mounted in connection with an alarm clock so as to be released to operate an electric switch when the alarm goes off.
Another object of my invention is to provide a mounting upon an alarm clock for receiving an actuator for an electric switch, said mounting having two positions for the actuator so that when the actuator is placed in one position it will turn on the switch and when the actuator is placed in the other position it will turn off the switch, as required to turn lights on and oil.
The figure is a perspective of a time operated light switch embodying the principles of my invention, parts being broken away to show details, and the clock and switch being indicated in dotted lines.
The actuator 7 is removably mounted upon the back 8 of the alarm clock 5 by a mounting having sockets 9 and 10, and the mounting consists of the base plate 11 adapted to fit against the back plate 8, an E-shaped spacing block 12 fitting against the base-plate 11, and the top plate 13 fitting against the spacing block, said top plate having notches 14k and 15 forming entrances to the sockets 9 and 10. The socket spaces between the base-plate 11 and the front plate 13 are rectangular in plan and the centers of the sockets are spaced apart to correspond to the spacing of the buttons 3 and 4E.
The details of the actuator 7 are as follows: The rectangular actuator base 16 is adapted to fit tightly in either socket 9 or 10. The outer barrel 17 is rigidly mounted to extend centrally from the upper face of the base 16, said barrel being adapted to fit closely in the notches 14 and 15. A second plunger barrel 18 telescopes loosely into the barrel 17 and has a head 19 forming aspring seat. An expansive coil spring 20 is mounted in the second plunger barrel 18 between the head 19 and the base 16.. A bearing bracket 21 extends upwardly from the barrel 17 near .its outer end and a latch lever 22 is mounted in this bracket upon the pivot 23, the tooth 24: at the outer end of the lever being adapted to engage the head 19 and hold the barrel 18 in the barrel 17 against the pressure of the spring 20. The handle 25 at the opposite end of the lever 22 is in position to be engaged by the arm 26 carried by the alarm key 27 of the clock. This arm 26 must be specially provided so as to be long enough to reach the handle 25. When the actuator thus constructed is placed in the socket 10 with the spring compressed and the latch set, the operation of the alarm mechanism will rotate the key 27 and cause the arm 26 to press downwardly on the handle 25 and release the actuator,
and the barrel 18 will shoot outwardly and strike the push button 3 and turn on the lights. If it is desired to set the mechanism to turn off the lightsat a given time, the actuator is removed from the socket 10 and placed in the socket 9. Then when the actuator is released the plunger barrel 18 will strike the push button 4 and turn off the lights.
The details of construction may be varied in many ways without departing from the spirit of my invention as set up in the following claims:
I claim:
1. The combination with an alarm clock, of a mounting secured to the back of the clock and forming a socket, an actuator mounted in the socket; said actuator comprising a base adapted to fit in the socket, a barrel extending from the base, a spring actuated plunger mounted in the barrel, latch mechanism for holding the plunger withdrawn, and a handle for the latch mechanism; and means whereby the handle is operated to release the plunger by the operation of the alarm key.
2. The combination with an alarm clock, of a mounting fixed to the back of the alarm clock and forming two sockets, one above the other; said mounting consistin of a base plate fitting against the back p ate of 7 the clock, an E-shaped spacing block fitting one socket to the other, and means whereby against the base plate, and: atop plate fitting the plunger iscl-ischargecllgwy the operation against the spacing block; said top plate of the alarm key. 1
having notches opening sidewise and form- In testimony whereof I have signed my 5 ing entrances to the sockets; a spring a-ctuname to. this specification.
ated plunger adapted to be ren'iovably mounted in either socket anclino'vccl from SWAN G. JGHNSON.
