PATRICK KENNEDY, OF NEW YORK, Y.

SIGNALING DEVICE.

To 51/ whom it may concern.-

Be it known that I, PATRICK KENNEDY, a citizen of the United States, residing in the borough of Brooklyn, in the county of Kings, in the city and State of New York, have invented certain new and useful Improvements in Signaling Devices, of which the following is a specification.

This invention relates to the class of elec-'.

tric signaling devicessuch, for example, as are used in lire-alarm signaling instruments. In some instruments of this class the person wishing to send an alarm-signal presses in a button at the box. In the said instrument, however, it is necessary that the person who wishes to send in a signal shall go to the box, open it, and operate the button or other device by hand. I

The object of the present invention is to diagrammatically, and Fig. 2 is a front view..

In the said drawings, A designates a signalbox, B the door thereof, and C a rectangle serving to designate diagrammatically the mechanism for transmitting the signal. This mechanism has nothing to do with the present invention and may be any one of the various mechanisms for the purposethat is adapted to be set in operation by pushing in a button.

In the construction shown herein D is the shank of the button to be pressed in so as to set the mechanism in motion for sending the signal.

In the present construction a cylindrical casing E is mounted on the door B, and in this casing is mounted a solenoid F, the coil of which is in a circuit composed of conductors c c c c c and including a battery or generator G and extending to a point Has a house, for example-at any distance from the box. At this point is situated a switch or circuit-closer I.- The movable core J of the solenoid is alincd with the shank or stem D of the button and forms in substance a continuation of said shank. This core is fixed at its outer end to a cup-she ed bu'tton K, which.

fits on and slides over t e casing E, its move- Specification of Letters Patent.

ment being limited by a screw or stud a and slot 6. A spring L retracts the button K when the circuit is broken at the switch I.

When one approaches the box to send a signal, he simply presses on the button K. This causes the core J to press upon and push in the shank or stem D, which sets the signaltransmitting mechanism in operation; but this may be effected electrically from the point H. If a person at this point wishes to send a signal, he merely closes the switch I for a moment when the current will flow by the conductor 0 from one pole of the generator G to a switch M, hereinafter called a "doorswitch, thence by conductor a. to the' solenoid F, through the coils of the solenoid, thence by the conductor 0 to another doorswitch M, thence by the conductor 0 to the switch or circuit-closer 3 at H, and thence by .the conductor 0 to the other pole of the generator G. The solenoid is thus energized and the core thereof caused to impinge upon and press in the shank or stem D, thereby setting the signal-transmitting mechanism in operation. The closure of the circuit at the switch Ineed only be momentary, and when the circuit is again broken thereat the spring L retracts the core J.

As the solenoid is mounted on the door B (which is hinged to the box at d) it is convenient to employ the switches M M, having contacts or terminals in the solenoid-circuit and so constructed that when the door B is opened to afford access to the signal-transmitting mechanism the circuit will be broken while the door is open and will be automat- I ically closed at this point when the door is closed. The two door-switches, one of which is obscured bythe other in Fig. 1-, are

both indicated in dotted lines in Fig. 2. It will suffice to say of these switches that one terminal of each is mounted on the door and the other on the box. I

. I am aware that it is not new, broadly, to provide a fire alarm signaling instrument with means for setting the signaling mechanism in operation from a distance, and this I do not claim. The present invention relates to the s ecific means for effecting this end and to til rectly. In other words, this invention does not employ two starting means, one to be 0 erated by hand and the other electrical y from a distance. The same button K that is pressed by hand or operated manually is ope means whereby the manually-ope 'eratable starting mechanism is actuated di- IIO erated electrically by making its stem form the core-of the solenoid.

1. An electrical signaling device, having a' button to be pressed in, manually, for setting the signaling mechanism in operation, a spring which retracts said button, and electrical means for operating said button from a distant point.

2. An electrical signaling device, having means for setting the signaling mechanism in operation, said means comprisin a button, a part thereof forming the core 0 a solenoid, the said solenoid, and a spring for retracting said core, an electric circuit extending to a distant point, said circuit including the coil of the solenoid, a generator, and a switch at said distant point, and the said generator and switch.

,3. A11 electric signaling device, having a shank or stem D to be pressed for settin in operation the signaling mechanism, a so enoid F axially alined with said shankor stem D, an electric circuit extending to a distant the button being mounted slidably on said casing.

4. .An electrical signaling device, having a J shank or stem tobe pressed for setting in operation the signaling mechanism, a solenoid axially alined Wlth'Sflld stem, the movable core of said solenoid, adapted to press in said stem when a'current is caused to flow through the coil of the solenoid, an electric circuit including the coil of the solenoid, and means for retracting the core of the solenoid.

In Witness whereof I have hereunto signed my name, this 10th day of February, 1905, in the presence Off/W0 subscribing Witnesses.

PATRICK KENNEDY.
