ELECTRICAL PLUG-RECEPTACLE.
To all whom it may concern:y
Be it known that I, GEORGE B. THoMAs, a citizen of the United States of America, and residing at Bridgeport, in the county of Fairfield and State of Connecticut, have invented a certain new and useful Improvement in Electrical Plug-Receptacles, of which the following is a specification.
My invention relates to plug receptacles and particularly to flush receptacles of the type described in Goodridge 7 54,863 the object of my -invention being to improve in several features the construction shown therein.
In the accompanying drawings, Figure 1 is a vertical elevation, partly in section, of my improved receptacle; Fig. 2 is a vertical section at right angles thereto; Figs. 3 and 4 are plan and side elevation respectively of the porcelain; Figs. 5 and 6 are vertical and horizontal sections on the lines 5-5, Fig. 3 and 6-6, Fig. 4,' respectively; Figs. 7 and 8 are side elevations at right angles to each other, of the terminal tubes, the binding screw being shown detached in Fig. 8; and
Fig. 9 is a vertical section of the porcelain showing a modified construction.`
The body A of the receptacle, whichis of porcelain or other suitable insulating material, is preferably cylindrical and has formed in it two longitudinal holes to receive two metal tubes B, B. The forward ends of the latter are provided with shoulders b, b, which rest against offsets in the porcelain, while the rear ends of tubes are smashed down to form terminal lugs b1, b1 which are then perforated and threaded to receive binding screws s. This construction does away with the customary set screw, since the tube is prevented from falling out of the porcelain in one direction by the shoulder b and in the other direction by the binding screw sa The .same result may be equally readily accomplished by forming a shoulder a at the lower end of the hole through the porcelain A1 against which the portion of the tube` adjacent the terminal lug b1 abuts when the tube B1 is inserted.
` The flattened terminal lug not only gives a firmer purchase to the binding screw since the latter now passes throughl two thick- Specification of Letters Patent.

nesses of metal, but it permits of lighter' metal being employed in the tubin itself, while at the same time-the flattened ug, being of greater width than the diameter of the tubeforms wings, which, entering slots b2 opening into the tube holes in the porcelain, serves to position the tube and prevent its rotation, so that the binding screw is always in proper position and the tube is held rigid during the screwing and unscrewscrews, which by reason of the novel cony struction of the lugs b1, are located deeper in the body. of the porcelain, (an added feature of safety) the binding screw recess R in the latter is fiared on both sides and above, as shown.
I claim as my invention:
1. A lug receptacle having an insulating body with a hole through it and a metal contact tube in said hole engaging said body to prevent the free passage of said tube throu h or its rotation in said hole.
2. lplug receptacle having an insulatin body with a hole through it and a meta contact tube in said hole engaging said body to prevent the free passage of said tube through or its rotation in said hole, said tube being flattened at one end to form a terminal lug, together with a binding screw carried in said lug. l
3. A lug receptacle having an insulating body with a hole through it and slots openin into said hole, a metal contact tube in sald hole and engaging said body to prevent the free passage of said tube through said hole, said tube being flattened at one end into a terminal lug forming wings engaging said slots in the porcelain, to ether with a binding screw carried in said ug.
4. A lug receptacle having an insulatin body with holes through it, a metal contaa .tube in said hole having one end flattened to form a terminal lug, means in connection name to this specification, in the presence of Wilth said hghto1 prevnt the otation of said two subscribing witnesses. l tu e inl sai o e an a in ing screw carried in Said lug, saidporcelain` having a! GEORGE B THOMAS' 5 flared recess to accommodate the binding Witnesses: l screw and leading in Wires. Gr. W. GOODRmGE,
