ELECTRIC' SWITCH.

Application filed-0ctober 7, 1920. Serial No. 415,282

To all whom it may concern:

Be it known that I, JosnrH M. RONALTER,

a citizen of the United States, residing at.

Stafford Springs, in the county of Tolla-nd and. State of Connecticut, have invented certain new and useful Improvements in Elec-i trio Switches; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it zipper-- tains to make and use the same.

The object of the invention is to provide tion at the moment of the operator or at-r tendant; and more especially to provide an apparatus for the purpose indicated in which an ordinary alarm clock may be positioned when it is desired to time the switch for operation automatically, the clock or time piece under ordinary conditions being used for its normal purpose and with these objects in view the invention consists ina construction and combination of parts of which a preferred embodiment is shown in the accompanying drawings wherein;

Figure 1 is a side view of the device showlation therewith.

Figure 2 is a front view.

ing; an alarm clock arranged in operative re- Figure3is a detail view of the clutch bit for engaging the alarm key.

Mounted upon a suitable base 10 having a seat 11 for an alarm clock 12 of the ordinary commercial type is a standard 13 carrying a revoluble switch spindle 14 to the front end of which is attached a setting knob 15 and to the rear end of which is fixed a clutch disc 16 perforated as shown at 17 for engagement with the prongs of an ordinary alarm clock key 18. A coiled sprin 19 may be arranged upon the spindle to old the clutch disc in engagement with the prongs of the alarm key and also to maintain a proper yielding Contact of the switch tongue 20 in position for engagement with a terminal 21 shownin the'drawing as of arcuate form, said switch tongue and terminal 21 being connected by circuit wires 22 and 23 with thejbinding posts 24 with which connection may be made to a lighting circuit.

7 Arranged in the path of movement of the switch tongue are the stops 25 and 26 serving to check therotary movement of said tongue in either direction, and respectively 1n contact with the terminal 21 and out of contact therewith, according to whether the switch at a predetermined time set by the alarm clock is to be either opened or closed. The alarm clock obviously may be set in the ordinary way to be released at a predetermined time, and when the alarm is released r the key 18 is rotated and communicates motion through the clutch disc to the spindle of the switch which causes the switch tongue either to come into Contact with or to move out of contact with the terminal 21 until checked by one or the other ofthe stop pins 25 and 26. The clutch disc is screw threaded on the spindle 14 so as to turn. Obviously if the switch is to remain closed, to correspondingly maintain the lighting circuit closed until a predetermined time at which it is desired that it shall be opened, the

switch tongue should be arranged in the position indicated in full lines in Figure 2 substantially in contact with the stop pin 25 and in Contact with the terminal 21, and when the alarm is released said switch tongue will be turned to the dotted line position as in Figure 2. On the other hand if the desire of the operator isto leave the circuit open and have it closed at a predetermined time in advance the switch should be pulled against the tension of spring 19 and moved across contacto26 so that when the alarm sounds the switch tongue will be turned until it comes into contact with the stop pin 25 and therefore in engagement with the terminal 21, whereupon further movement of the switch tongue will be prevented, the clutch disc turning idly upon the switch spindle.

What is claimed is y 1. An electric switch apparatus including a switch device having a clutch, and an alarm clock, means to urge the clutch into engagementwith the spindle of said alarm mounted therein, a switch arm on said spindle, means engugeable by the arm to enclose an electric circuit, stop means engageable by said arm, and an attaching clutch on the spindle and it spring to urge said clutch away from the standards and to permit retraction of the spindle to facilitate movement of the switch arm across the stop means.

3. An electrical switch apparatus having :1 bnse provided with it seat for an alarm clock, a revoluhle spindle mounted upon a standard of said base, a switch tongue carried by the spindle, an arcuate terminal arranged in the path oil movement of said switch tongue the switch tongue and terminzil being electrically connected with hinding posts stops for limiting the movement of the switch tongue, a perforated clutch disc mounted upon the spindle for engagement. with an alarm clock key, and a spring coiled upon the spindle in terminal engagement with said clutch disc for yieldingly holding the latter in turning relation with the spindle.

In testimony whereof I aflix my signature in presence of two witnesses.
