ELECTRIC FIRE-ALARM.
SPECIFICATION forming part of Letters Patent No. 332,638. date December 15. 1885.
Application filed March 14, 1885.
.To aZZ whom it may concern:
Be it known that I, SIDNEY A. CHAsn, a citizen of the United States, and a resident of Evart, in the county of Osceola and State of Michigan, have invented certain new and useful Improveinents in Electric Fire-Alarms; and I do hereby deelare that the following is a full, clear, and exact description of the in- Vention, which will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawing, which forms a part of this specification, and which represents a diagram of my improved electric fire-alarm apparatus.
My invention has relation to electric firealarm apparatus, and it contemplates certain improvements upon the apparatus for which application for Letters Patent, Serial No. 155,579, was filed by me on the 10th day of February, 1885; and 'it consists in the improved construction and combination of parts of an apparatus in which the breaking of the main-line circuit, which is preferably accomplished by means of a common telegraph-key, will operate by the one movement both the alarm-releasing instrument in a normallyclosed local circuit and a local alarm bell placed in a normally-open local circuit, as will be hereinafter fully described and elaimed.
In the accompanying drawing, the letters A A indicate the eleetro-magnet, the coils of which receive the main-line current through the main-line wires B B. O is the armature, and D is the frame, which is formed with perforations E and F for the passage of the two contact-screws G and H, all of which parts are of the construction generally used in relays. The contact-screws are both tipped with platinum or other similar metal, instead of one being tipped with an insulating material, as in the usual relays, and the screw G, which passes through the perforation E of the bridge or frame D, and with which the armature comes in contact when it is attracted by the magnets in the closed main-line circuit, is insulated from the frame bya bushing, I, through which itpasses, or by any other suitable means, which may readily suggest themselves to the expert mechanic. Awire, J, is secured to this screw, and passes from it to a binding-post, K, into Serial No. 158,886. (No model.)
which is secured one, L, of the wires, extending to the alarm-releasing instrument X and the battery Y upon the lclosed local circuit. The contact-screw H is in direct contact with the frame or bridge D, and a Wire, M, passes from the frame to a binding-post, N, in which is also secured a wire, O, which passes to the Vibrating alarm-bell P, which may be of any desired construction, and to the battery Q upon the open local circuit. Two wires, R and S, are connected to the armature and pass to two binding-posts, T and U, to one,T, of which the other Wire of the closed local circuit, which Wire is lettered V, is secured, while the other binding-post, U, has the wire VV of the open local circuit secured to it. It will now be seen that as the main-line circuit is opened by the person giving the alarm, the preferable means for accomplishing this being a common telegraph-key, the armature will be released from the magnets, and thus cease contact with the insulated eontact-screw, which will open the closed local circuit formed by the said insulated screw, the wire J, wires L and V, Wire R, and the armature, which will cause the alarm-giving instrument to sound the alarm. The released armature will come in contact with the eontact-screw H, which will close the open local circuit consisting of the said contact-screw, the frame D, wires M, O, XV, and S, and the armature, and the closed circuit will sound the hell-alarm until stopped by the closing of the main-line circuit, which will attract the armature to the insulated contactscrew, again opening the closed bell-alarm circuit, and closing the open circuit having the alarm-releasing instrument, bringing the said circuits back into their normal state.
Having thus described my invention, I claim and desire to secure by Letters Patent of the United States- As an improvement in electric fire-alarm apparatus, the combination, with an electromagnet located in the main-line circuit and having the usual metallic yoke, of the two contact-screws, one of which is in direct contact with the metallio yoke, while the other passes through an insulated aperture in the said yoke, and the armature arranged to come in contact With the insulated contact-screw IOO insnlated contact-screw when the main-line when attracted by the vmagnets of the electromagnet, and to come in contact With the u-ncircuit is broken, an alai'm-releasing instrument located in a normally-closecl local circuit7 oneof the wires leading from its electro-magnet oonnecting' with the insulated. contactscrew, while the other Wire connects With the armature of the main-line electro-magnet, and the alarm-hell located in a normally-open local circuit, one of the wires of which connects With the metallic yoke of the main-line electro- Witnesses:
