SPECIFICATION forming part of Letters Patent No. 676,289, dated June 1 i, 1901. Appiiuaiion met 113mm 23,1901. serai no. 49,312. dit modem To a/ZZ whom it may concern:

Be it known that I,` CHARLES WAGNER, a. citizen of the United States, and a resident of thecity of New York, borough of Manhattan,

in the 'county and4 State of New York, haveinvclited a new and Improved Switch for Electric Lamps, of which the following is a full,

, ed out in the claims.

A practical embodiment of the invention is represented in the accompanying drawings, forming a part of this specification, in which similar characters of reference indicate corresponding parts in all the views.

Figure l is a sectional side elevation of the -improvement as applied and with the switch in a turned-on position. Fig. 2 is a similar view of the same with the switch in a shuto position. Fig. 3 is a sectional plan view of the improvement on the line 3,3.in Fig. '1. Fig. 4 is a similar view of the same on the line 4 4 in Fig. 2;; Fig. 5 is alike view of the same on the line 5 5 in Fig. 2. Fig. 6 is a perspective view with parts in section of the stationary contact-holder, and Fig. 7 is a perspective View of the tiirnable contact-holder. A hollow supportA is'screwed or otherwise secured to a suitable bracket, base, or the like, and in this snpportis secured a tube B, through which extend the wires C C' C2, of which the wires C C are connected with the source of electricity supply and the wires C C connect in the usual manner with the electric lamp D, secured to the upper end of an imitation candle E, supported at its lower end on a ring E', carried by the central stationary tube B. The wire C extends directly through the supportA and tube to the lamp, while the upper end of the wire C and the lower end of the wire C2 extend through openings in the tube B to connect with contactpins F F', secured in a contact-holder G, made in the forni of a disk, of an insulating material, such as porcelain. The contact-holder G ring J by a -spring L, the lower end of which is seated on the upper end of the support A. The contact-holder I is formed in its periphery with recesses I', engaged by lugs or projections N', formed on the inside of a sleeve N, mounted to4 turn loosely on the upper end of the hollow support A, the lower end of said sleeve resting on a suitable collar O, secured by la set-screw or other means on the support A. The upper end of thesleeve N engages the lower end of the imitation candle E, and the sleeve N completely incloses the contact-holders G and I, as well as the metal ring J, the washer K, and the spring L, so that said parts are not visible from the outside aiid are not liable to be clogged by dust and other impurities. The under side of the contact-holder G is also provided with recesses G2, spaced from the heads F2 of the contact-pins F F', adapted Vizo-be engaged by the upper projecting ends of the contact-pins H H when a quarter-turn is given to the holder I upon-turning the sleeve N to the position shown in Figs. 2, 4, and 5.

It is understood that when the sleeve N is turnedthe contact-holder I turns with it, and when the sleeve is in the position shown in Figs. 1 and 3 then the contact-holder I has its contact-pins H H' in register with the heads F2, of the contact-pins F F', and a the said pins H H' are connected with each other by the metal ring .I it is evident that the switch is now in a turned-on position and the current passes through the wire C', the pins F and H, the metal ring J, the pins H' F' to the wire C2 and to the lamp D'. When a quarter- IOS turn is given in either direction to the sleeve N, then the contact-pins H H move out of engagement with the vheads 'F2 of the contactpins F F and move in engagement with the recesses G2 of the insulating-disk G, so that the switch is in a turn ed-oif position, and consequently the electric current is broken and the light of the lamp D is extinguished. By

mounting the contact-holder I yieldingly, as described, it is evident that the projecting rounded-off upper ends of the contact-pins II -H readily engage the recesses in the heads F2 ofthe contact-pins F I1" or the recesses G2 in the insulating-disk G.

By the arrangement described the unsightl y key heretofore used in electric switches is completely dispensed with, and the sleeve N, used for turning the switch into an open or closed position, not only incloses the working parts, but alsoV gives a very neat appearance to the entire lamp.

It is expressly understoodlhat it does not.

matter in which direction the sleeve is turned to make or break the circuit.

Having thus fully described my invention, I claim as new and desire to secure by Letters Patent-- 1 1. A switch for electric lamps, comprising a stationary tube for the lam p-wires, a contact-holder of insulating material and se` mougted to turn and carrying said movable cont ct-h'older, as set forth.

2. A switch for electric lamps, 4comprising a stationarytube lfor the lamp-Wires, a contact-holder of insulating material secured to the tube, spaced contact-pins in said holder and connected at one end with the electric wires, a second contact-holder of insulating material and -mounted to turn on the tube, contact-pins yieldingly mounted in said second contact-holder and adapted to move in and'out of engagement with said contact-pins in the stationary holder, and a sleeve mounted to turn and carrying said movable contactholder, the sleeve inclosin g both contact-holdtact-holder of insulating material secured to y thetube, spaced contact-pins in said holder holder, a metallic ring for electrically connecting the contact-pins in the movable holder, and a spring-pressed Washer pressing said ring, to hold the latter in engagement with its contact-pins, asset forth.

4. A switch for electriclamps, comprising a stationary disk of insulating` material and 'containing spaced contactpins having .recessed lower ends, arevoluble disk of insulating material and having spaced contactpins loosely mounted therein and adapted to enter the recessed ends of the pinsof the stationary disk, a ring below the revolubledisk and upon which the lower ends of the pins thereof rest, and a spring-pressed washer of insulating material below the ring, as set forth.

. 5. A switch for electric lamps, comprising a stationary disk of insulating material and containing spaced contact-pins, and a second disk of insulating material mounted to turn and having spaced contact-pins adapted to move in or out of register with the contactpins on the stationary disk upon turning the movable disk, said stationary disk havin-g recessesspaced from the stationary-disk contact-pins,'the recesses being adapted to be engaged by the contact-pins on the turnable disk, as set,forth.

Y 6. A switch for electric lamps, comprising a stationary contact-holder having spaced contacts, a movable 'contact-holder having spaced contacts, and a revoluble sleeve carrying the movablecontact-holder', as set forth.

7. A switch for electric lamps, comprising a stationarydisk containing spaced contacts, a second disk mounted to turn and having spaced contacts, .and a revoluble sleeve con- 'nected withv the second disk and inclosing both of. the said disks,-as set forth.

In testimony whereof Iy have signed my nameto this specication in the presence of `three subscribing witnesses.'
