ELECTRIC-LAG HT FIXTURE.

SPECIFICATION forming part of Letters Patent No. 452,367, dated May 19, 1891.

Application filed September 8, 1890. Serial No. 364.280. (No model) T0 all whom it may concern.'

Be it known that I, JOHN GEORGE FISCHER a citizen ofthe United States, residing at East Saginaw, in the county of Saginaw and State of Michigan, have invented a new and useful Electric-Light Fixture, of which the following is a specification.

This invention relates to electric-light tures; and it has for its object to provide a cut-out or device by means of which electric lights may be placed in or removed from the circuit in a convenient and rapid manner.

The invention further consists in combining with a cut-out conductors of fusible metal, which in the event of the conductors being short-circuited or overloaded shall be instantaneously fused, thus breaking the circuit and avoiding damage.

The invention further consists in so constructing the cutout and fusebox as to present a neat appearance and enable it to be built into the iinish of apartments, so that lights may be conveniently introduced wherever desired7 the boxes at points where no lights are used or desired being covered with dummy rosettes.

The invention further consists in certain details of construction, which will be hereinafter fully described, and particularly pointed out in the claim.

In t-he drawings hereto annexed, Figure 1 is a vertical sectional view of a cut-out and fuse-box embodying my improvements. Fig. 2 is a plan view of the cover of the device having the conductors attached. Fig. 3 is a transverse sectional view illustrating a modiiication of my invention. Fig. at is a longitudinal sectional view showing said modification. Fig. 5 is aplan view of the cover used in connection with the modified form of my invention. Fig. G is a transverse sectional view, on a reduced scale, of one of the dummycovers used in connection with my invention.

Like numerals of reference indicate like parts in all the iigures.

1 designates a circular box provided at its edge with an annular shoulder or bracket 2, to which on diametrically-opposite sides are secured the metallic catches 3, having hooks 4t at their outer ends. The catches 3 are secured by means of the screws 5, andthey are provided at their projecting ends with b1nd ing-screws 6, to which thc conductors 7 7 are attached.

S designates the cover, which is provided with an annular groove 9. Suitably secured to the cover by means of screws 10 are the springs 11, which extend into the annular groove 9. These springs, when the cover is placed in position, are engaged by the hooks et of the catches 3, thus serving to retain the cover in position upon the box, and also to establish electrical contact with the catches 3 and through the latter with the conductors 7. The springs 11 are provided at their inner ends with binding-screws 12, which are connected by strips 13 of fusible metal with the binding-screws 14, that serve to secure the metallic plates 15 to diametricallyopposite sides of the cover intermediately between the springs 11. The opposite ends of the plates 15 have bindinglscrews 16, to which are attached the ends of the conducting-wires 17, that support the light 18.

In operatiomthe boxes 1, with the conductors 7 attached, maybe arranged and suitably attached in all places where there is a probability of electric lighting being required W'hen no lights are to be used, the boxes may be provided with dummy covers 19, such as have been shown in Fig. 6 of the drawings, and which are simply ornamental rosettes having annular grooves 2O and springs 21 for attachment to the boxes, said springs 21 being electrically connected so as to make no break in the circuit in case of series lighting. When lights are to be introduced, the dummy covers may be removed by simply turning them partially so as to disengage the springs 21 from the catches S, after which the covers 8, carrying the lights, may be substituted. In like manner the lights may be readily cut out whenever desired and du mmycovers substituted in their place.

In Figs. 3, 1, and 5 I have illustrated a modication of my invention by which instead of using a circular I use a rectangular box, the sides of which are provided with springcatches 3, having hooked ends 4, adapted to engage the springs 1l, that are attached to the sides of the cover. The latter maybe removed by sliding it longitudinally upon the box until the springs pass out of engagement with the catches. The latter are to be suit- IOO ably connected with the conductors, and the springs upon the cover are connected with the fusible inet-al strips 13 and with the conducting-Wires 17, that support the light. The operation of this device is substantiallyidentical with that above described.

My invention is susceptible of other niodiiications than that herein described. Thus, for instance, the springs might be attached to the box and the catches to the cover Without departing from the spirit of iny invention.

Having thus described my invention, 1 claim and desire to secure by Letters Patent of the United States- In a cnt-out tor electric lights, the combination of a box 1, having shoulder 2, catches 3, having hooks at secured to opposite sides of said shoulder, the cover 8, having groove 0, the springs 11, secured to said cover and extending into the groove thereof, the lightsupporting conductors 17, and the fuse-strips 13, connecting the latter with the springs 11, all constructed and operating substantially as and for the purpose herein set forth.

In testimony that I elaini the foregoing as iny own I have hereto affixed my signature in presence oi. two Witnesses.
