Application filed Kay 1, 1916. Serial No. 94,731.

To all whom it may concern v Be it known that I, MARTIN MERKEL, a citizen of the United States, residing at Celestine, in the county of Dubois and State of Indiana, have invented certain new and useful Improvements in a Si al-Operating Mechanism, of which the ollowing is a specification.

This invention relates to a device for operating an alarm mechanism and has for its object to rovide means which in connection with an a arm bell and particularly one operated 'by an electrical current will when set for operation cause said bell to ring when any door or window to which it is connected is opened or an attempt made to open it. v

A. further object of the invention is to provide an operating device for the purpose which shall be simplaof few parts, easily applied by any one to any existing bell circuit and which may when desired, as in the daytime, he readily moved out of operative position.

With these as the princi al objects in view and others to be hereinafter set forth, the invention consists of the construction and arrangement of parts here described-and illustrated in the accompanying drawing, in which: i

Figure 1 is a diagrammatic view showing the device in use in connection with a door and window.

' Fig. 2 is a side elevation the operating member enlarged, and,

3 is a cross sectional the line Referring to the drawing by numerals, 'l-(l indicates a portion of a building of any kind in which 11 is a lower room'and 12 an upper room. in the upper room there is mounted on the wall ,or in some position convenient to a bed if one should so desire it, a call hell of conventional type from which circuit wires 14 extend to the room below where they terminate at a switch 15 of the usual push hutton variety fastened on one of the walls, one of the circuit wires 1% passing through a battery 16 from which an electric current is derived to operate the hell 13 when the switch 15 is closed.

Over the switch 15 is placed a cage or carrier 17 comprising two spaced plates 18 and 19 connected together by two oppositely disposed brace bars 20 that have outwardly turned feet 21 to rest upon the wall on each the cage upon the wall and for through the side of the switch 15, through one of which feet is passed a pin or screw 22 for mounting permitting the same to swing to one side away from the switch when desired as clearly shown in dotted lines in Fig. 3. Through the plates 18 and 19 are formed a lurality of holes 23 for pins 24 which slide ii'eely each in a hole in each of said plates and at such an angle that their inner ends overlie the push button 25 of the switch 15 and normally maintain a short distance from said push button when set for operation by cords, wires, or the like 26 that extend each from a pin 24: toa door 27, window 28 or other closure which it is desired to protect. Each pin 24 has an eye in its outer'end to which a cord or wire 26 is fastened and passing from thence said wire or cord is led through guides or over pulleys 29 to the door or window to which it is attached, the same being sufiiciently tight when (1001' or window is closed to hold the pin 24 away from the button 25 and the spring 130 surrounding said pin under com= pression. The springs 30 which surround the pins are preferably helical springs and hear at one end against the plate 12 and at the other end against a split pin 31 passing pin 24,

As many pins :24 will be employed as there are doom and windows to protect and when all or said doors and windows are closed the pins 2 will be drawn away from the push button 25 of the switch 15 as shown in however, a door or window is unlawfully opened the cord or wires 26 attached to said door or window will be loosened and the spring 30 on the pin 24 being relieved pushes said pin toward the butten 25 and engaginghsaid button presses it inward and closes t e circuit through the bell 13 at the switch 15. The bell thus separating will warn anyone in the neighborhood that someone is trying to enter through a door or window in an unlawful manner.

During the day or when the device is not required, the cage or carrier 17 will be turned to oneside' away from the switch 15 so that the pins 24 will not contact with the-button 25 when the cords 26 are loosened by the openin of .doors and windows.

Whi e I have shown and described what I consider at the present time to be the best form of this invention, it is to be understood that various changes may he made in the construction and arrangement of the parts within the limit of the claims without departing from the spirit of the invention.

I clalm: v

1. In a signal operating mechanism, a fixed support, a switch mounted on said support and controlling an alarm, a carrier pivoted on said support to swing in the plane thereof over said switch into operative position therewith, resiliently actuated means mounted on said carrier for operating said switch, and a flexible connection between said actuating means and a dooror window for holding said means inoperative when the door or window is closed.

2. In a signal operating mechanism, a switch controlling an alarm, a carrier pivotally mounted to swing over said switch, a plurality of resiliently operated pins mounted in said carrier and adapted when released to press upon and operate said switch, and

a flexible connection between each of said pins and a door or window which when closed withdraws said pin from the switch and leaves the latter inactive.

3. In a signal operating mechanism, a push button switch, a carrier ivotally mounted to swing over and away om said switch, a pluralit of pins mounted in said carrier and slida' le into engagement with said switch, a spring acting on each of said pins to force the same to close said switch, and a flexible connection from each of said pins to a closure, which closures hold said connections under tension and the pins away from the switch until one of said closures is opened.

4. In a signal operating mechanism, a

' fixed support, a switch mounted on said support and controlling an alarm, a carrier mounted on said support to be swung in the plane of the support into position over said switch, resiliently actuated means mounted on said carrier for operating said switch, a hinge pivot forming the sole means of mounting said carrier on the fixed support, and a flexible connection between said actuating means and a door or window for holding said means inoperative when the door or window is closed.

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