SPECIFICATION formingpart of Letters Patent No. 293,553, dated February 12, 1884:.
Application filed October 9, 1862.
To aZZ whom it may concern Be it known that I, SIGMUND BERGMANN, of New York, in the county and State of New York, have invented a certain new auduseful Improvement in Combined Gas and Electric Lamp Fixtures, of which the following is a The object I have in view is to produce a bracket for supporting both an incandescing electric lamp or lamps and a gas burner or burners, which bracket shall be capable of being folded or swung in' any manner, while both the gas and electrical connections are maintained. I may accomplish this in either of two ways: first, by employing an-electrical swinging bracket of suitable construction such, for instance, as is shown in the patent of T. A. Edison, N0. 248,420-and support ing upon said bracket a flexible tube attachedto a gas-pipe, and carrying at itsouter end a gasburner, the flexible tube extending longitu'dinally along the electrical fixture, so that when the latter is folded or bent the tube bends with it; or, secondly, I may employ a construction,supporting flexible electrical conductors, which run to a lamp-socket supported at the end of the gas-bracket, a swiveled these conductors and the main house-wires to prevent injury to the wires when the bracket is swung. v
My invention is illustrated in the annexed drawings, in which Figure l is a view in elevation illustrating that form of my invention in which a flexible gas-tube is employed; Fig. 2, sectional view of a portion of the same; Fig. 3, a view in elevation illustrating that form in which a swinging gas-bracket and flexible electrical conductors are used 5 Fig. 4, a sectional view of a plug which I prefer t9 use for connecting the flexible electrical conductors with the house-wires, and Fig. 5 a plan View of the interior of said plug.
Referring to Figs. 1 and 2, A is the swinging electrical bracket, supported from the wall of a room at B, and carrying an incandescing' electric lamp, 0, provided with a suitable shade, D. The wires which convey current the ceiling of a room.
to the lamp pass through the bracket, suitable (No model.)
devices for maintaining connection being provided at the joints a b.
E is a flexible tube of rubber or other suitable non-conducting material not affected by the gas. One end is attached to the projecting end of a gas-pipe, F, the tube being slipped over the end of the pipe, and a ring, 0, being used to hold it. A suitable cap covers the joint. a ring or band, cl, projecting above the bracket A. The outer end of the tubeis slipped over the end of a short section of metal pipe, G, the flexible .tube ending at d and the metal tube G at the dotted line a. i
The pipeor tube G supports a gas-burner, H, of ordinary construction, except that the The tube E passes through gas-cockf is placed at the side, as shown, in-
stead of at thebottom, where it would be inconvenient to reach it. The tube G is supported from the electrical fixture by means of a clamp, I, (shown in detail in Fig. 2,) consistingof two halves attached together in the middle by screws 9. The tubes E (G are held in one end of the clamp, and the bracket A in the other. The clamp may be either of metal or of insulating material. The second form of my invention is illustrated in Figs. 3, 4E, and 5. The fixture shown inFig. 3'is a suspended swinging bracket.
L is a gas-tube extending downwardly from From near the lower end of tube L the swinging gas-bracket M extends horizontally, provided at its end with the burner H.
To the lower end of tube L is attached the socket N, which is provided with the interior terminals usual with incandescing electriclamp sockets. Thehouse circuit wires are con-' nected with'such terminals, in this case by conductors combined in the flexible cord Q.
P is a plug having exterior terminals corrcsponding with the interior terminals of socket N. To such terminals are connected wires whichv are combined inthe'flexible cord Q. The cord Q is supported from the gas-bracket at h, and at itsouter endthe conductors contained in said cord enter the incandescing Ice this plug is to prevent injury to the wires in the flexible cord Q when the bracket is turned outer casing, S, having interior contact-plates,
IO j a piece of lead wire, 1, forming a iand j, to which, respectively, are attached, by means of binding-screws, the wires 7c and Z, contained in the flexible cord Q. From plate safetycatch, extends to plate 112.
To plate m is attached aflat spring, n,which extends down from said plate a SllfflClBIll) distance to bear against the inside of the screwthreaded band or ring 0, which encircles the wooden plug T. The plug T is swiveled to the outer casing, S, so that it turns independently of such casing. It is turned by means of rod q, to which is attached a thumb-piece, s.
A metal plate, 19, is attached to the bottom ofplug T, and from said plate awire runs through the plug to plate a, to which the rod q is attached. A spring, 0, coiled around rod q, makes contact with both plates to and r, and preserves good electrical connection between them when the plug is turned. The ring 0 and plate 12 make contact with the corresponding interior terminals of the socket N when the plug is screwed into said socket.
The plug just described is adapted to b used in other ways than that mentioned, and will therefore be made the subject of a separate application for Letters Patent.
It is evident that the latter form of my invention is applicable to brackets which extend horizontally from the wall as well as to the suspended fixture. In this case the socket N would be attached to the stationary part-of the gas-fixture near'its inner end, connection being made from the socket to the house-wires in the wall, and the swiveled plug employed as above. It will be seen that in either form the electric lamp and the gas-burner will be swung together and simultaneously.
1. Thecombination, with a jointed swinging bracket, of a gas-burner and-an electric lamp supported by such jointed swinging bracket, and a flexible connection supported by said jointed swinging bracket for supplying one of such two devices with its lighting agent, the other being supplied through the bracket, substantially as set forth.
2. The combination, in a swinging bracket, of a jointed portion supporting both an incandescing electric lamp and a gas-burner, and so constructed and connected as to supply one of them with its lighting agent, and a flexible portion supported by the jointed portion, so constructed and connected as to supply the other, substantially as set forth.
3. The combination, with an electrical jointed swinging bracket carrying concealed circuit-wires, of a flexible tube supported by said bracket and carrying a gas-burner, sub stantially as set forth.
4. The combination, with the electrical jointed swinging bracket carrying an electric lamp, of the flexible gas-tube connected with the wall gas-pipe, the metal pipe G, secured to the end of the flexible tube and carrying the gas:burner, and the clamp I, supporting the .pipe G from the electrical bracket, sub
stantially as set forth.
