SWITCH OR CIRCUIT-CONTROLLER.

SPECIFICATION forming part of Letters Patent No. 334,143, dated January 12, 1886.

Application filed July 18, 1884.

To all whom it may concern:

Be it known that I, EDWARD WVEsToN, a subject of the Queen of Great Britain, and a resident of Newark, in the county of Essex and State of New Jersey, have invented certain new and useful Improvements in Switches or OircuitBreakers, of which the following is a specification, reference being had to the drawings accompanying and forming a part of the same.

My present invention relates more particularly to devices for controlling circuits or branch circuits containing incandescentlamps which are supported by chandeliers or brackets. In many of such cases the presence of a shade over the lamp or the conformation of the bracket makes access to the usual circuitbreakers or switches very inconvenient, as the lamp holder or socket and the switch are generally combined, or the switch placed very close to the lamp. To avoid this objection, I have devised a switch that may be readily inserted at any point in the pipe of the bracket or chandelier where it will be easy of access.

This device consists of a short section of pipe constructed in a manner to be readily inserted in a length of pipe by cutting the latter and securing the ends to the section, in com bination with insulated terminal contacts secured within it, and a circuit-breaker adapted when fitted into the said section to make or break connection between the terminals, according to the position of the key and separ rable contact-surfaces.

Referring to the drawings for a description of the details of the device, Figure l is a longitudinal vertical section of the invention applied to a bracketarm. Fig. 2 is a plan view of the part to which the terminals are attached Fig. 3, a plan view of the switch for use therewith; and Fig. 4 is a detail of the switch mechauism.

A designates the tube or pipe of any chandelier or bracket, containing conductors B O, that are run through the pipe to the lamp or other device for which the pipe may be used as a support.

D is a short section of pipe, which may be enlarged, as shown, when necessary. It has internallyscrew-threaded ends and joins the Serial No. 138,019. (No model.)

two sections of pipe A when the latter is cut at any desired point for the insertion of a circuit-breaker. In one side of the section Dis an opening, into which is inserted a flat ring, E, of insulating material, preferably with a flange, c, with holes for screws to fix it to the pipe. In'the inner wall of the ring E are cut vertical grooves b, and to the upper edge of the ring are secured contact-strips F, that project downward partly within or over the grooves b. One of the circuit-wires, as O, is severed and its ends attached to the contact plates or strips F in any convenient manner.

G is a plate of insulating material having a flange, H, that forms a cup that fits into the ring E. To the outer face of the flange H, and in position to register with the strips F, are secured resilient strips K, that are bent at right angles toward one another, as shown in Fig. 1. The plate G is inserted in the ring E with the strips F K in contact, and fastened in this position by any suitable means. To the plate I secure a switch or circuit-breaker for making or breaking connection between the strips K, and thus controlling the circuit through the bracket. The specific construction of switch for this purpose may be greatly varied, that shown, however, being a convenient and mac ticable form.

L is a metal plate secured to the plate G within the cup or flange H. M is a rock-shaft in raised bearings N, cast on the plate L. Extending out from shaft M is an arm, P, with rounded end,which bridges over the space between the ends of strips K when held in aver- 8 5 tical position. At right angles to this arm is another, 0, between which and plate L is a spiral spring, X, that has a tendency to turn the shaft and throw the arm I? out of a vertical position. In line with arm 0 is a projection, R, turned downward at right angles and ending in a roller, T. Under the shaft M is a spindle, S, that passes through the plates L and G, and is turned by a key,V. Secured to this spindle is an elliptical plate or block, WV, with notches d d. Vhen this plate is turned by the key V, its edge bears against the roller T and turns the shaft M. \Vhen the roller enters one of the notches d, the end of arm 1? makes contact with both strips K and completes the circuit between them.

If the key be turned farther in either direction, the spring X exerts a force that throws the plate W around suddenly into the position indicated in dotted lines, Fig. 4, which allows the armP to tilt and to leave one of the strips K. In this way the circuit is interrupted without spark.

It is immaterial for the purposes of this invention in what manner the section I) be formed or connected to the pipe A.

Without therefore confining myself to the described construction in the particulars hereinbefore specified, what I claim is 1. The combination,with a pipe-section and insulated contactstrips, forming circuit-terminals and secured in the same, of contactstrips on an insulating-plate, and adapted to enter the pipe and to register with the terminals therein, and a switch for making and breaking electrical connection between the contact-strips, substantially as set forth.

2. The combination, with a pipe-section, an insulated ring inserted in an opening in the side of the same, and circuit-terminals secured to the ring, of a plate carrying contactstrips constructed to register when inserted into the pipe with the terminals on the ring, and a switch for making and breaking connection between the contact-strips, all as set forth.

3. The combination,with a pipesction having an opening in its side, an insulating-ring inserted in said opening, and circuit-terminals secured to the ring, of a flanged plate of insulating material, contact-strips secured thereto in position to register when inserted into the pipe with the terminals therein, and a switch secured to the plate and adaptcd'to make and break connection between the contact-strips, all substantially as set forth.

4. The combination, with the pipe-sections A and joining'section D, containing the insulated terminals F, of the removable plate G, contact-strips K, and switch mechanism for making and breaking connection between the strips, these parts being constructed and com bined in substantial] y the manner set forth.

5. The combination, with the pipe-sections A, joining-section D, the insulating-ring E, and terminals F, of the flanged plate G, contact strips K, and switch for making and breaking connection between the strips, as set forth.

In testimony whereof I have hereunto set my hand this 16th day of July, 1884.
