CLARENCE D. FLATT, OF BRIDGEPORT, CONNECT IGUTQ ,MOLDING-RECEPTACLE.

Specification of Letters Patent. Patenteo'llDec, 2Q, 1910.

Application filed November 27, 1909. Serial No. 530,177.

T 0 all whom it may concern:

Be it known that I, CLARENCE D. PLATT, a citizen of the United States, residing at Bridgeport, county of Fairfield, State of Connecticut, have invented an Improvement in Molding-Receptacles, of which the following is a -specification.

This invention relates to the class of receptacles used in connection with wooden molding as a means of attaching incandescent lamps and other devices directly to the molding, and the invention has for its object to produce an extremely simple and inexpensive receptacle which shallbe made in one piece and have no loose parts.

Molding receptacles as heretofore produced, so far as I am aware, have been made to consist of two parts or members, one memher being a block carrying the terminals and other metal parts and the other member being simply a cover for the terminal block. These two parts have no connection with each other until the receptacle has been installed when the cover is secured over the block by means of screws passing through the cover and into the molding on which the receptacle is mounted. After the receptacle is installed, the bindmg screws on the terminal block are inaccessible. This has proved a serious objection as it is desirable that the binding screws in addition to being fully protected should be made readily accessible after the receptacle is installed for the reason that in installing each successive receptacle on a line of molding the wires mustbe pulled out of the grooves-in the molding. As there is usually no slack in the wires the'strain upon the wires in pulling them out far enough; to skin and to attach to another receptacle tends to loosen the binding screws of the adjacent receptacle, after which the vibration of buildings tends to loosen the binding screws still more, and as they are not accessible they are apt to be left in a dangerous condition.

My present invention enables. me to produce a stronger and cheaper receptacle which shall comprise a complete terminal block and cover in a single piece.

An additional advantage of my present structure is that in addition to having no loose parts the shoulders, recesses, etc. of the receptacle always bear a certain fixed relation to each other, which is impossible in a receptacle having two or more parts. By

providing openings in the sides of the re ceptacle in alinement with the binding screws, I leave the binding screws fully protected but easy of access, thus makingit convenient and safe for an operator to'install any number of receptacles on the same line of molding and then to pass from one 1 to another and give the binding screws in each the necessary final setting.

In the accompanying drawing forming a part of this specification in which similar reference characters indicate the same parts in all of the views, Figure 1 is an elevation partly in vertical section showin the receptacle in place on a molding witthe cover strip in place; Fig. 2 a transverse section of the molding and cover strip with the receptacle in end elevation; Fig. 3 a plan view of the receptacle in placeas in use; Fig. 4 an inverted plan view of the receptacle detached; Flg. 5 a longitudinal section on the line 5-5 in Fig. 4:; Fig. 6 a tranverse section on the line 6-6 in Fig. 4.; Fig. 7 an illverted plan view of the screw shell detached; and Figs. 8 and 9 are elevations of the terminals detached.

10 denotes a molding having the usual grooves 11 for wires, 12 cover strips which are secured to the molding by screws 13 and cover the wires 14, and 15 a lamp the base 16 of which may be screwedintothe shell of the receptacle.

17 denotes the receptacle as a whole which may be made of insulating material, as porcelain, and may be made of, an ordinary or preferred configuration an isattached to the molding by screws 18..

For convenience I will describe thereceptacle as comprising a base 19 and a socket 20 in which is secured a screw shell 21 ada pted to be engaged by a lamp or other base as shown in Fig. 1

22 denotes longitudinal grooves in the under side of the base which receive the wires 14, said grooves being gradually deepened as they approach the middle of the base.

-the socket, and 26 lateral openings in the sides of the base which lead into openings 25 to give access to the bindingscrews, as will be more fully explained.

27 denotes the center contact which carries a binding screw 28 and 29 the shell contact which carries; a binding screw 30, said binding screws being in alinement with the lateral openings. The center contact lies in one of the openings 25 and an L-Shaped attaching portion thereof, indicated by 37, extends through an opening 31 in the bottom of the screw shell and is attached to a boss 32 on the bottom of socket by means of a screw 33 which extends upward through the base and engages the attaching portion of the contact. The shell contact lies in the other opening and a branched lL-shaped attaching portion thereof, indicated by 38, extends through opening 31 in the bottom of the screw shell and is attached in place by screws 34 whichextend upward through the base and through holes 35 in the bottom of the screw shell and engage threaded holes 36 in the contact.

The operation will be obvious from the drawing.

lln installing a receptacle, the wires are pulled up from the grooves, skinned and passed over the contacts and under the binding screws which are loosened to receive them and then turned down tightly upon them. Access may be readily had to the binding screws at any time through openings so. It should be noted, however, that the contacts and binding screws are thoroughly protected as they lie well within the base, as clearly shown in Fig. l, and are moreover protected on the under side by projections 2%.

Having thus described my invention ll claim:

I. It one piece insulating molding receptacle comprising a base having longitudinal grooves in its under face to receive wires and an integral socket portion extending from said base, said grooves gradually deepening as they approach the middle of the base, openings being formed in said base between said grooves and said socket.
