COUPLING FOR ELECTRIC-LIGHT AND GAS FIXTURES.
SPECIFICATION forming part of Letters Patent No. 497,251, dated May 9, 1893.
Application iiled November 19, 1892. Serial Ne. 452,543. (No model.)
To all whom it may concern.-
Be it known that l, GEORGE PEErLEs, a citizen of the United States, residing in the city and county of Philadelphia, State of Pennsylvania, have invented a new and useful Improvement in Couplings for Electric-Light and Gas Fixtures, which improvement is fully set forth in the following-specification and accompanying drawings.
My invention consists of a coupling for electric light and gas fixtures, the construction and operation of the samebeing hereinafter set forth.
Figure l represents a longitudinal section of a coupling embodying myinvention. Fig. 2 represents perspective views of the parts of the same separated. Figs. 3 and 4t represent longitudinal sections of the coupling with dierent attachments thereto. Fig. 5 represents a side elevation of the form shown in Fig. 4. Fig. 6 represents a perspective View thereof, the parts being separated.
Similar letters of reference indicate corresponding parts in the several figures.
Referring to the drawingsz--A designates a collar with a head A and neck A2. To said neck A2 is screwed the sleeve B, within which is fitted a tubular plug O, whose head D bears against the internal flange E of said sleeve, and whose threaded neck F passes through said ange.
G designates an annular plug which is both interiorly and exteriorly threaded, it being screwed upon the neck F, and upon the interior of a sleeve II, which latter has fitted to it on the interior thereof, the head J of the tubular plug K, whose neck L passes through the internal iange M of said sleeve Il, said head engaging said flange.
N designates au insulator which is inter posed between the neck of the collar A, and the head of the plug O. Encircling said head A is a shouldered insulator I).
which is connected with either of said parts by means of of a screw T which enters an L.- shaped slot U in said insulator, after the manner of a bayonet joint.
In Fig. 3 I show a sleeve V' secured to the neck F of the plug C. In this case, the plug G, packing R, sleeve A and plug K have been removed, and they are substituted by said sleeve V.
In Figs. et, 5 and 6 I show said collar V removed, and in lieu thereof I employ a sleeve B having tongues B2 projecting from one end thereof for engagement with a sleeve W, said sleeve B being screwed to the plug X, which unlike the plug C in the other figures, is solid.
In the sleeve XV are slots Z to receive the tongues B2, and on the sides of the walls of the slots Z are lugs C', which are adapted to enter the recesses D on the inner ends of the tongues B2, so that when either the sleeve B or sleeve W is turned, the lugs C enter the recesses D thus locking said sleeves for temporary purposes.
E designates screws which pass through the two sleeves B', W and bear against the plug X for tightening said parts.
The coupling shown in Figs. l and 2 is elnployed for gas and electric light fixtures. In this the collar A is screwed to a gas pipe, and the plug K has the fixture coupled toit, thus permitting said fixture to be connected with the coupling without turning the former as the sleeve II turns freely on the headJ of the plug K. It will also be noticed that the several parts are insulated so that the coupling may be employed for an electric fixture or a combination electric and gas fixture. It will also be noticed that when the coupling is used for a gas fixture, owing to the bore through the several parts of the coupling, gas may flow through the same from the service pipe to the fixture, without leakage, owing to the gastight nature of the joints thereof.
The coupling Fig. 3, is employed where a solid joint is required, and the coupling may be turned with the fixture in the operation of connecting it with the gas pipe, without taking apart the coupling.
In Figs. il, 5 and 6, the collar A is adapted to be screwed to a gas pipe as asupport, and the wires of an electric light fixture are passed IOC) through the sleeve W, and directed out ofthe saine through the inner ends of the slots Z, whereby they may be connected with the wires in a Wall, ceiling, 85e.
In Fig. 6, only two of the tongues B2 are shown. The tongues B2 enter the slots Z in the sleeve W, and the said sleeve is turned so that the lugs C enter the recesses D of the sleeve B. The screws E which are passed through openings in said sleeves W and B lock the said sleeves together.
Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is-
1. The collar A with head A and neck A2, the flanged sleeVeB connected with said neck, the tubulaiplug C passing through said sleeve and having the head D bearing against the ange'of the same, and a sleeve on the neck F of said plug, and insulators between said parts A, B, C, H, and around said parts A, B, substantially as described.
2. The collar A with head A and neck A2, the iianged sleeveB connected with said neck, the plug C passing through said sleeve, and having a head D bearing against the flan ge of the same, the interiorly and eXteriorly-threaded plug G engaging the neck of the plug C, the langed sleeve H engaging with said plug, the tubular plug K having a head J which engages with the flange of said sleeve I-I, and a neck L which passes through said flange and insulators between adjacent parts, all
combined and operating substantially as described.
3. The sleeve B with a head and neck, in combination with the encircling sleeve II, the end collar A, and the interposed insulators N, P, Q, substantially as described.
4. The cellar A, sleeve B, and a plug connected therewith in combination with a sleeve provided with tongues, and an interlocking sleeve provided with slots to receive said tongues, substantially as described.
5. The sleeve W, the slot Z and lugs C, in combination with the sleeve B having tongues B2, With recesses D for interlocking said sleeves, substantially as described.
6. In a coupling substantially as described, an attaching collar A, in combination with the plug C, the flanged sleeve H, the interiorly7 and eXteriorly-threaded plug G, which is screwed to the neck of said plug C, and engaged by said sleeve II, the headed plug K passing through said sleeve I'I and engaging with the flange thereof, and the packing R interposed between the plug G and head of the plug K, the bore of said plugs C, K, being continuous of each other and of the attaching collar A of the coupling, substantially as described.
