entrees-connect ELECTRIC SWITCH.

To all whom it may concern Be it ltnown that I, Jenn B. Gums, a citizen ofthe United States, residingat Detroit, county of Wayne, State of Michigan, have invented a certain new and useful 1111-. movement in Remote-Control Electric Switches, and declare the following to be a fulh clear, and exact description of the same, such as will enable others skilled in the art to which it pertains to make and use the same, reference being had to the ac companying drawings, which form a partof this specification.

This invention relates to remote control electric switches and has for its object such a switch of difi'erent construction and mode of operation from the devices of: the prior art and which is capable oi being constructed at less cost. Its operation is by mag netic attraction and gravity alone" In the drawingsz-Figure 1, is the front elevation of the switch. Fig. 2, is a vertical section of the switch partly in elevation. Fig. 3, is a side elevation of the switch on a similar scale, showing the connectors dropped out of contact with the terminals. Fig. 4: is a frontelevation of the switch in the same position, as in Fig. 3. Fig. 5, is a detail of the connector.

Each of the wires coming into a house or building is broken forming terminals 1 and 2 that are mounted on an insulating bed sucli fastened to the insulating bed A and is provided with a hollow core 8 and a Swiss iron armor e. In between the core 3 and the armor i are the necessary insulating windings 5. The core and the iron armor are an important part of my invention as these permeable substances serve to collect the magnetic flux and concentrate it so as to make the s lenoid. or sucking magnet very m l r ore efiicient with a given current 5. otherwise be the case. By the term of construction ente this magnet with a pair of a total voltage of 3 and an of about 2G High tension opcte control switches liable to u if something goes wrong with enl hence are interdicted by The plunger rod 6 is recip L118 hollow core 3 and carries a cross head of insulating material 1' upon mounted the two connect 8.

g springs 9 for a purpose hereinafter to be described. The conductor 10 leads from one end of the winding 5 about the core to the binding post 11 and from thence to a push button switch C where a push button 12 may close the circuit through the battery 13 to the binding post 1 1, from thence through the conductor 15 to the lower end of the coil.

Arranged just below the solenoid B is a magnet D provided with a softiron core 16, windings 17 and armor 18. This magnet D is provided with a circular catch 18 that is hinged thereto. The coil is energized through the conductor 19 which leads from the common binding post 11 and the conductor 20 that leads from the other'end of the coil to the binding post 21 and thence to the push button switch (3 where it is controlled by the push button 22.

The operation of the device is as follows i' The push button 12 is pressed, thereby establishing a circuit through the battery 13, the conductor leading therefrom, the binding post 1 1. the conductor 15 through the coil about the plunger 6, out the other end of the coil, by the conductor 10 to the binding post 11 back to the push button switch. This serves to energize the solenoid B which sucks the plunger rod 6 up so that the spring contacts bridge the terminals 1 and 3. The magnetic in the solenoid, while it is energized also serves to open out the circular catch 18 of the magnet D so that it lies directly in the path of the plunger rod 6. When the push button 12 is released, the plunger rod 6 starts to drop, (the switch being vertically disposed) but is caught by the catch 18 so that it does not drop far enough to allow the spring contacts 9 to leave contact with the terminals. These spring contacts 9 by reason or their resiliency contact the terminals although he connections drop slightly before the cat-ch engages with the plunger, The circuit is new eli ectually closed. until it is again de- The opening is eccent- V a g the push button of the.

The plungler rod then drops by gravity, breaking t e contact with the terminals and opening the main circuit.

From the above description, it will be seen' that my device is readily and cheaply constructed and it does not require a constant flow of current in order to keep it in closed or open relation and that it is so designed that a few dry batteries will efi'ectually operate it. Another important feature is the fact that it operates entirely by mag netic attraction and gravity, doing away with all s rings or other mechanical devices What claim is I A remote control electrio'switch, having in combination, a vertically disposed solenoid, a pair of terminals located thereabove, a vertically'reciprocating plunger rod adapt ed to be drawn upward by energizin said solenoid, a connector carried by said p unger rod and adapted, when the plunger rod is drawn upward, to contact the terminals and close the circuit therethrough, a magnet located just below said solenoid and provided with a hinging catch, said catch, when the solenoid is energized, being adapted to be drawnoutward under the plunger rod by the magnetic flux of the solenoid and thereby hold the plunger rod so as to kee the connector in contact with the termina s and the said magnet being adapted, when it is ener-v plunger rod drops by gravity and breaks the connection between the connector and the terminals.

In testimony whereof, I' sign this specification in the presence of two witnesses.
