.To all whom it may concern.-

Be it known that I, PHILIP'H.' FIELDING, a citizen of the United States, residing atvthe city of New York, in the borough of Manhatd tan and State of New York, have invented certain new and useful Improvements )in Electrical Receptacles, of which the followin is a full, clear, and exact description. f

his invention relates to receptacles for incandescent lam s, and has s ecial reference to devices of this character willich are adaptin other places where the rece tacles Vare to be supported lupon the face oi) a plate.

. The object of the invention is to provide a chea4 and simple form of rece tacle-which will he substantially waterprooi), r`which can be mounted and dismunted very easily, and in which the bindin -`screws and metal parts are properly housef and protected. L

T e invention consists of the construction hereinafter described and claimed.

In the accompanying drawings, Figure 1` is t e receptacle mounted in operativeposition in connection with its supporting-plate and the Wires.- elevatlon of the receptacle. Fig. 3 is a central setionthereof, and Fig. 4 is -a rear elevation with the protecting and supporting cap removed. l.. 5 The receptacleiconsists of a body a, ofinsulatingmatenahhavingac lindrical cavit a',-

dY partially linerirbyv a metallic threaded bushing a2 to receive an `The outer ed e of this open at its front face -an Edison lamp-base.' bushing is turned over to form a ange and rest against the rim ofl the bod t a. .The body a has a cylindrical ,or partal ly-conical rear portion which terminates forwardl in an annular flan e as, whereby it is possibleto Bass the body of the receptacle through a ole in a where the ange as' will rest against the face of the plate; Such a plate is shown at Aand it may be understoodto representthe face. of

I an electric sign Aorany vother sup ortingplate. The .opening in the4 late wl be` of such diameter. as to be v'ust ed by the rear portion of the receptac e when ithas passed through it.A A

`cavity a. bolt, and when turned up tightly the cover B ofthe ig. 2 is a rear slate and bring'it to a positionl To hold the body of the receptacle Aiirmly in position in' the plateA, I. ro'vide a dome-v shaped cover B, preferably o orcelain, hav ing an internal diameter and slliape such as to iit neatly over the rearwardly-extending portion of the body a and ada tedto pass entirely over said portion and avin a face or shoulder to rest against the rear fce of the plate a. To hold this cover in place, I use a central s crew-bolt b, which passes through a central hole in the cover and through another central hole in the bod a, said hole terminating at the bottom o a pocket c2, formed in the bottom. of n the cylindrical A nut screws'over the end of the and the body portion a are drawn together, their'shoulders abutting the-respective faces late A and clamping the annular edge of the said plate between t em, and thus .securely hold1ng`the receptacle in place. On the rear face'of the body a a rectangular integral projection of l porcelain a* is formed, through which the screw-bolt passes and constitutlng a dividing-wall Valong the center of the rear face of the receptacle'. On one side'- of this dividingwall 1s mounted a metal plate c, carryin a binding-screw c and conf nected with the threaded bushing a2 by means of a rivet or wire d, extending in a d1- rection parallel to the axis of the rece tacle and'through the wall of the bod d. (lh the otherside of the dividing-wal is another metallic plate e, having a binding-screw e and connected by means of a similar but shorter wire f with a metallic late located -on the `bottom of the cylindrica cavityclv and having `.a centraly contact-surface to receive the central contact of the lampsbase. The cover B is provided with four slots or notches g, yarranged in pairs inv such position thatthe circuit-wires conveying the current to and from the receptacle ma pass through thesenotches andenga e'witli thel bindingosts c and e without. eing cut or` spliced. n Fig. 4 it will be seen that'the insulation of the wires is removed from a short section and the bare Wire then passed under the 'bindingscrews and caught thereby..v This Wiring operation is performed before theicover is adroo justed. After the Wires are properl connected the cover is adjusted by si'mp y saddling it over the wires, allowing them to pass into the notches, and then securing by means of the central screw, as before explained.

It will be seen that the operation of wiring this receptacle is v ery simple and that the manner of holding it in position is likewise simple. The cover not only clamps the plate a, Jfor the purpose of holding -the receptacle in place, but also serves as a protection for the metallic exterior parts, preventing contact therewith by any extern obj ect. This Jfeature of my invention is subject to a slight modification in case it is desired to use the receptacle underA some other condition than that described. "For instance, the cover may protect the contacts without necessarily clamping the plateA. In such a case the cover would not be so deep, but may terminate at any point after overla ping the rear face of the receptacle upon which the metal parts are mounted. This cover protects the ive parts from moisture to a great extent.

Having described my invention, I claim- 1. In a device of the character specified, the combination with a supporting-plate having an opening, of an electric receptacle comprising two parts, one of which carrieg binding-posts, contacts and the other live parts, and partly passes through the opening in said plate and having a face abutting .one side of sa'id plate, while the other is a cover adapted to protect the said posts and liveparts, and having a face abutting the other side of said plate,"and means for securing the two parts together andv whereby the supporting-plate may be clamped between the said faces abutting it for sustaining the receptacle in position thereon.

2. In a device of the character specified, the combination with a supporting-plate having an opening therein, of an electric receptacle comprisinga body having a socket in its front end and binding-posts Jfor live conductors on its rear end, and an engaging face for said supporting-plate intermediate of its Jr'ront and rear ends, and its rear'end assing through said plate, and a' cover adjusted over tthe binding-posts on the rear end of the body and having an engaging face bearing against the supporting-plate for sustaining the receptacle thereon.

3. A supplort for electric lam s, comprising a late aving an opening t erein, a receptac e Within said opening having a shoulder abutting against said late around the oppning and a cylindrica cavityb with a t eaded metallic bushing therein, and having a rear portion projecting through said openin a cover for said rear portion having a perip eral' edge adapted to abut against.

said plate, and separate means for drawing said parts toward one another.

, 4. A support for electric lamps comprising a plate having an'openingtherein, a receptacle within said opening and having'a shoulder abutting against said plate and a rear portion projecting through the opening, terminal connections upon said rear portion in a plane substantially remote from the plane of said plate, a cover having a peripheral edge adapted to bear against said plate, and separate means for connecting said cover and receptacle.
