COMBINED GAS AND eLso'rmo LBGHT FEXTURE.

srncmxcnrrorr forming part of Letters Patent No. 490,903, dated January 31, 1898.

Application filed January 22, 1892. Serial no. 419.045. on model.)

To all whom it may concern: I Be it known that I, FRANCIS X. GARTLANID, a citizen of the United States, residing in the cityand county of Philadelphia, State of Pennsylvania, have invented a new and. useful Improvement in Couplings for Electric and Gas Conductors, which improvement is fully set forth in thefollowing specificationand accompanying drawings.

Myinvention consists of acoupling for electrio and gas conductors having an interlock ing plug between its knuckles, insulated in said knuckles and pipes having openings for the conductors and connected with said knuckles, the plug having a bore with openings on opposite sides and communicating with the said pipes.

It v further consists .of the combination of parts hereinafter setforth.

the knuckle B, said contact rings Figure 1 represents a perspective view of conductor embodying my invention. Fig. 2 represents a longitudinal section thereof.

tached portions thereof. a

Similarletters of reference indicate corresponding parts in the several figures..

Referring to the drawings:-A and B des-' ignate the knuckles of a coupling, the knuckle A being between the collars of the knuckle B, said knuckles being connected cap D at one end, and the screw E and asuitable washer at the other end. The knuckle A is provided with a branch pipe F, and the knuckle B with a branch pipe G, and an arm G, each branch having in its wall the open-.

ings H, H, for the passage of the electric conductors J, J. In the ends of the knuckle A, are contact rings K, which are in contact with contact rings L located within the collars of K, L, being suitably insulated from the knuckles and having the conductors J connected with them as followsz-The conductors in the branch F lead to and are connected with the contact rings in the knuckle'A. The conductors in" the branch G, lead from and. are connected with the contact rings in the knuckle B. -I The plug C,"has a bore M which opens in opand recesses N around the *peposite places,

. riphery of the plug communicating with the 'ends of said bore. One of the recesses comcontact rings .by a plate Q,

N byaconicalj plug (3, which is retained in position bythe the same being provided in said knuckle, and

municates with the bore of the branch F, and the other recess communicates with a bore P,

in the upper collar of the knuckle B, said here communicating with the bore of the branch G, it being seen that gas is admitted into the branch G, passes through the bore P, and is thus directed into the bore M from whenceit enters the bore of the branch F, by-which'it is conveyed to the fixture or attachment. Should the knuckles be turned from'the right line shown in Fig. 2, the gas is not out o&, as the recesses N form the communication for the bore P with the bore M, and that of the bore M with the bore of the branch F.

In the arm G which connectsthejcollars of the-knuckle B, there is a channel, to permit the portion J of the conductor J therein to pass from the contact ring in the lower collar of the knuckle B,to the said branch G, said portionJ beiu g covered on the inner side and said plate being secured thereto by means of a screw R. The plate is accessible when the knuckle Ais removed from the knuckle" B, and may be detached, thus uncovering the portionJ' of the conductor, applicatiomremoval or repairs. It will be seen that-when the knuckles are turned so as to change the direction ofthe conductors, the contact rings K and L always remain in contact, thus maintaining the electric circuit and the conductors are not twisted or strained. The branch is provided with a cutting oh? and letting on the dent.

gas, as is evi- The insulating material for the contact rings K in the knuckle, is in the form of grooved disks K, to receive said contact rings,

with tongues K", which enter grooves K of the arm G,

for purpose of gas key S, for

7 proper opening H in engage with the walls thereof, whereby twisting or turning of said contact rings, and consequent breaking or disconnection of the conductors J is prevented when the knuckles are rotated, it being-evident that the disks, contact rings-and conductors. move as one with the knuckle A.

Having thus described my invention, what claim as new, and desire to secure by Letters Patent, is:---

1. A coupling-for electric conductors con-v sisting of knuckles with an interlocking plug, contact rings insulated in said'knnckles. and

pipes connected with said knuckles and provided with openings for the electric conductors, said plug having a bore opening on opposite sides of the plug and communicating with the bores of the pipes, said parts being combinedsubstantially as described.

. 2. A coupling for electric conductors consisting of knuckleswith an interlocking plug, insulated contact rings in said knuckles, pipes connected with each of said knuckles having openings therein, electric conductors in the openings in each knuckle leading to the contact rings in the said knuckle, and an arm on one of said knuckles having a passage for a portion of an electric conductor from its contact ring to the opening in the pipe, said parts being combined substantially as described.

3. A coupling for electric conductors having knuckles with an interlocking plug, insulated rings in said knuckles, electric conductors connected with said rings and pipes connected with said knuckles having openings for said conductors, the bore of said plug having openings on opposite sides in peripheral recesses of said plug, and communicating with the bores of the said pipes, said parts being combined substantially as described.

4. A coupling for electric conductors having knuckles with grooves therein, an interlocking. plug contact rings in said knuckles,

insulating grooved disks receiving said rings and having tongues entering said grooves in the knuckles, and engaging with the walls thereof, and pipes connected with said knuckles, said parts being combined substantially as described.
