CUT-OUT.

SPECIFICATION forming part of Letters Patent No. 425,726, dated April 15, 1890.

Application iiled May 14, 1885. Serial No. 165,547. (No model.)

T0 all whom t may concern:

Be it known that l, CHARLES BATCHELOR, of New York, in the countyand State of New York, have invented a certain new and uscful Improvement in Electric-Light Fixtures, of which the following is a specification.

This invention relates to the use of incandescent electric lamps for'street-lighting, and particularly to a cnt-out, whereby, when a lamp-carbon breaks, the current will be shunted around that lamp.

In an incandescent street-lighting system it is preferred to place several lamps in series and use a high electro-motive force to supply the circuit, and if one lamp breaks all the others in that series circuit will be extinguished unless means are provided for closing circuit around the broken lamp.

My invention also includes the arrangement of supporting parts for the lamp and cut-out device, and of a reflector and devices for protecting the whole from the weather, all as more fully hereinafter set forth and claimed.

My invention is illustrated in the accompanying drawings, in which- Figure l is a view in elevation` of a streetlainp inrcomplete form embodying said invention; Fig. 2, a vertical section of the same; Fig. 3, a top view of the cut-out apparat-us, and FiO. 4 a perspective view of a portion of the same.

A is a metal disk, which supports the lamp and cut-out. Upon the under side of said disk is an insulating-disk B, to which is secured an incandescent electric-lamp socket C of that class having terminals which engage with the terminals of the lamp when the same is screwed into the socket, and thereby complete the circuit of the lamp. C is the lamp.

Upon the upper side of disk A is placed the cut-out mechanism. This consists of an electro-magnet D wound with fine wire, whose vyoke or back piece a is supported upon the projection h, rising from the disk. The armlever (l carries a contact-point L. A post fz, risingfrom base A, but insulated therefrom` has centrally pivoted upon it a lever 7.1, which has at one end a catch or projection Z, and secured at the other end a spring m. Beyond the catchZ t-he lever has a screw-threaded extension, on which is screwed the insulatinghandle n. Upon the outer side ot' lever 7c is secured by screws o a flat spring p, which carries a contact-point r. Rising from the base A is a metal standard E. Upon the top of this are two insulated binding-posts s and s. The spring m is attached to this support E, its attaching post being insulated by a washer t. The post 1t, to which the spring f is attached, is insulated from base A by washer t.

The circuits are as follows: The main-circuit wires l and 2 extend, respectively, to the binding-posts s 8'; thence wires 3 l extend through an aperture in the base to the lampsocket. From the binding-posts s s extend also line wires 5 6, which are connected with the magnet-helices, and also wires 7 S, which extend, respectively, to the posts e and 1T.

Above the standard E extends vertically a rod F, which has a iiange o and a screwthreaded part w, and terminates in a ring G. The reflector I, placed above the lamp, lits at its upper part closely around the base Ae The cut-out mechanism is covered by a metal shell II, having suitable apertures, through which pass the rod F, the two binding-posts s s", and the handle n, the last ben ing screwed upon the end of the lever after the shell Il is placed in position. The lower edge of the shell surrounds the upper edge of reflector I, and both are secured to the base A by screws, as at x. Above the whole is placed the cap K for protecting the apparatus from the weathern The rod F extends 'through an aperture in the cap, rubber gas kets being placed around it to make the joint moisture-tight, and the whole being secured together by a nut Ii, screwed upon w.

By means of ring G the apparatus lis hung upon any suitable support.

The shell II, reflector I, and cap Il are preierably of tin or other metal,

The operation of the cut-out mechanism is as follows: Vhile the lamp is in circuit the cur- IOO rent in thc line wire shunt 5 6 is not sufficient to energize the magnet D so that it will draw its armature toward it, and therefore the lever d is held back by its spring, and the point of the catch Z rests upon a section of insulating material y, Which is interposed in said lever; but if the lamp-carbon breaks, or from any other cause the current ceases in the lampeircuit 3 4, more current passes through 5 G, and the magnet draws its armature-lever for- Ward against the spring f, past the catch l, and-the lever 7c then falls by the tension of the spring m, carrying' with it the flat spring p, so that the contacts hr come together, and the shunt 7 8 is closed around both the lamp and the magnet and is locked by the catch Z, engaging With the armature-lever. By this means the magnet itself is cut out of circuit, while at the saine time the armature-lever is looked positively, so that it does not vibrate when the magnet is so cut out, and the shunt around the lamp and magnet is closed at points separate from the locking device and with a separate spring-pressure. Vhen the broken lamp has been replaced by a new one, the handle mwhoh, as stated, projects through an opening in the covering-cap, is raised, and the spring f then draws the armature-lever back and breaks the shunt around the lamp and magnet.

What l claim isl. The combination, with an electric lamp, of an electro-magnet in a shunt around the same, an armature-lever controlled thereby, a spring-catch for locking said lever in its forward position, a contact carried by said armature-lever, a contact moved by said springcatch, and a shunt around the lamp and mag* net, including said armature-lever and said contacts, substantially as set forth.

2. The combination, With an electric lamp, of an electro-magnet in a shunt around the same, the armature-lever controlled by said magnet, the contactpoint on said lever, the spring locking-arm 'for said lever, the platespring carried by said locking-arm and hav ing a corresponding contact-point, and the shunt, including said armature-lever and said contact-points, substantiallyT as set forth.

This specioation signed and witnessed this 29th day of April, '1885.
