UNITED STATES PATENT OFFICE.
IVAEEEN P. FREEMAN, OF BROOKLYN, NEIV YORK, ASSIGNOR TO IVILLIAM F. JOBBINS, OF SAME PLACE.
INDICATOR FOR ELECTRIC LIGHTING SYSTEMS.
SPECIFICATION forming part of Letters Patent No. 287,654,'dated October 30, 1883.
Application filed March 19, 1883. (No model.)
To aZZ whom it may concern:
Be it known that I, WARREN P. FREEMAN, a citizen of the United States, and a resident of Brooklyn, Kings county, New York, have invented certain Improvements in Indicators for Electric Lighting Systems, of which the following is a specification.
The object of myinvention is to provide an electric lighting system with an indicating-circuit, whereby the extinction of any lamp and its location in the system will be automatically indicated at the central station; and this object I attain by combining with the cut-out devices of the electric lamps a signaling-circuit which is put into operation by the movement of the cut-out in throwing the lamp out of the lighting-circuit, as hereinafter more fully described.
In the accompanying drawings, Figure 1 is a diagram illustrating the manner in which a signaling device may be combined with the cut-out of a lamp; Fig. 2, a diagram of a series of lamps with the signaling-circuitand the indicator at the station; and Figs. 8 and at, corresponding diagrams of a modified form of indicating device.
In Figs. 1 and 3 Ihave shown the signaling devices as combined with the automatic cutout shown and described in my application for a patent filed March 9, 1883, Serial No. 87, 620; but it will be understood that they may be combined with various forms of cut-outs and lamps.
In the diagram, Fig. 1, m and m are the opposed fine and coarse wire coils of the cutout in the shunt-circuit and main lighting-circuit of the lamp, and a is the intermediate armature, with a pin, a, on which rests the outer end of the catclrlever N, pivoted to the support for the magnet m, and in this instance acted on by a spring, 8. On the outerend of this lever is formed an upward projection, whiclnwhen the lever is maintained in its elevated position, takes into a notch of a circuitbreaking wheel, B, similar to those used in district telegraph systems. On the periphery of the wheel bears the insulated contact-spring (2, connected by the conductor 1 with the next lamp, and so on to the battery L and indicator E at the station. On the face of the wheel bears another insulated contact, f, connected by the conductor 2 with the next lamp on the other side, and so on back to the indicator and battery. As a means for operating this wheel when released by the depression of the catchlever N, a rubber band or a cord, 1), may be coiled around a hub on the wheel and pro vided with a spiral spring, I), connected to a post, a, on the frame.
The breaker-wheel B of each lamp is provided with different numbers or lengths of insulating-pieces or circuit breaking spaces from that of each of the other lamps; or each group of lamps may have circuit-breakers of a different character from those in the other 6 5 groups connected with the station on the same signaling-circuit,which includes the battery L and the indicator E, Fig. 2, the latter consisting of a telegraphic sounder or call-bell or equivalent indicator. When a lamp becomes extinguished and automatically cut out of the lighting-circuit by the attraction of the armature n by the shunt-coil m and the fall of the lever N, the circuit-breaking wheel B will be released and caused to turn by the spring I), so that the contact 6, in passing over the insulating-spaces, will break the circuit a certain number of times. The indicator R makes a corresponding signal, and thusindicates at the central station the lamp or group of lamps where the trouble exists.
Instead of using circuit-breaking wheels as indicators 011 the lamps, I may make use of other devicesas, for instance, I may so construct the device that the fall of the lever N on 8 5 the cutting out of the lamp will throw a resistance-coil into the circuit and indicate this resistance on a galvanometer at the station, coils of different resistances being used on different lamps or groups of lamps, as indicated go in the diagrams, Figs. 3 and 4. In this case the lever N is provided with an insulated c011- tact-finger, 6, connected by the conductor 1 with the next lamp, and, as before, to the battery L and indicator E, which in this case is a galvanometer. IVhen the lever N is in its raised position, this finger c is in contact with a point on the conductor 8, leading to the conductor 2 to the next lamp, as before. hen
the lever N falls, the finger 6 comes into contact with a point on the conductor 4, also connect I or group of lamps, said signal being adapted 20 ed with the conductor 2, and having a resistance-coil, B, so that this throwing of the resistancecoil into the signalingcircuit will cause a corresponding indication at the galvanometer R by the deflection of its needle. By providing the lamps or groups of lamps.
with coils B of diii'erent resistancesthree ohms, five ohms, seven ohms, &c. the corresponding deflection of the needle will indicate 7 the location of the lamp which has been cut out of the 1ighting'circuit, as in the arrangement before described.
I claim as my invention 1. The combination of a series of electric lamps having cut-outs for the lighting-circuit, with a signaling-circuit having an indicator at the station, and a different signaling'device, substantially as described, on each lamp to be put in-operation by the movement of the cut-out to throw the lamp out of the lightingcircuit;
2. The combination of a series of electric lamps having cut-outs for the lighting-circuit, with a signaling-circuit having an indicator, R, at the station, and circuit-breakers on the lamps, the circuit-breaker of each lamp being adapted to be put in operation by the movement of the cut-out to throw the lamp out of 0 the lightingcircuit, substantially as set forth.
In testimony whereof I have signed my name i to this specification in the presence of two subscribing witnesses.
WARREN P. FREEMAN. Witnesses:
E. FORMAN, HUBERT HOWSON.
