HENRY T. PAISTE, OF PHILADELPHIA, PENNSYLVANIA.

OUTLET-FIXTURE FOR CONDUITS.

Specification of Letters Patent. Original application filed March 18, 1908, Serial No. 421,778.

Patented July 5, 1910. Divided and this application filed November 10, 1908. Serial No. 461,853.

To all whom it may concern:

Be it known that I, HENRY T. PAISTE, a citizen of the United States, residing in Philadelphia, Pennsylvania, have invented certain Improvements in Outlet-Fixtures for Conduits, (being a division of my application filed March 18, 1908, Serial N o. 421378,) of which the following is a specication.

My invention relates to fixtures particularly designed for use with conduits carrying electrical conductors, and more particularly with that type of fixture designed for the support of an incandescent lamp socket.

One object of my invention is to so construct a lixture of the type above noted, that the lamp socket proper, as well as its insulating case or shell, shall be provided with a substantial support and be rigidly held in place.

These and other advantageous ends I secure as hereinafter set forth, reference being had to the accompanying drawings in which Figure l, is a side elevation of one form of my improved fixture; Fig. 2, is a longitudinal vertical section of the lixture shown in Fig. l; Fig. 3, is a transverse vertical section taken on the line S, Fig. 2; and Fig. 4, is a perspective view of a iixture; the lamp socket and its protecting cover being omitted.

In the above drawings, A represents a casting provided with two outlets a, constructed for the reception of conduits B and B', and it will be noted that each of said outlets is provided at its extreme inner portion with a. relatively short threaded section a, while the remainder of its interior is unthreaded. Each outlet has a set screw a2 so placed that it may be made to engage the cylindrical surface of thatportion of a conduit inserted within the unthreaded part of said outlet. The casting A has the sides of its main portion liared, as shown best in Fig. 4, so as to form an approximately rectangular opening upon which may be mounted a protective casing C, usually of insulating material such as porcelain, within which is placed a lamp socket D. The opening in the casting A is -provided with inwardly projecting lugs a3 for the reception of screws c whereby the casing C is held in place, and there are also inwardly projecting ledges at for the recept-ion of. the. lam socket D. Said socket is provided with a shell CZ threaded in this case for the recep tion of an incandescent lamp, and has also a terminal plate d mounted at the bottom of said shell. This plate is held to the porcelain or other base piece ai* of the socket by a screw Z2 and is extended down one side of said base piece, as shown in Fig. 3, where it is provided with a terminal screw (Z3. The shell CZ is held to the base piece by screws cl, which also serve to electrically connect to it a plate (Z6 having a lug ex tended down the side of the base piece opposite the extension of the plate d and provided with a second terminal screw CZ?.

With the above arrangement of parts it will be noted that when the protecting casing' or covering C is firmly mounted upon the casting A by means of its screws c, it engages the projecting ends of the base piece el* of the socket D so as to rigidly hold these between itself and the ledges a4,- the thickness ofI said ends and the positions of said ledges being such as to accomplish this end.

I claim zl. A fixture consisting of a hollow structure having an end opening for the reception of a conduit and having also an enlarged central portion provided with a side opening, a pair of lugs projecting inwardly from the sides of the latter opening, a casing mounted over said opening, means whereby the casing is held to the hollow' structure, and a member confined between the casing and the lugs.

2. A fixture consisting of a hollow structure provided with an opening for a conductor and having also an opening for the reception of a lamp socket, lugs on said structure projecting inwardly from the sides of the latter opening, a protective casing mounted over said opening, and a lamp socket confined between said casing and said lugs.

3. A fixture consisting' of a hollow structure having an opening for a conductor and also provided with an opening for a lamp socket, lugs on said structure projecting inwardly from the body of the fixture on opposite sides of the lamp socket opening, a protective casing mounted over said opening, and a. lamp socket having its insulating base conned between said lugs and said protective casing.

4. The combination of a hollow structure having an opening provided with two pairs In testimony whereof, I have signed my of lugs projecting respectively on opposite name to this specification, in the presence of 10 lidles thereof, the lugs (pf one ptir having two subscribing witnesses.

o es, a casing mounte over t e opening and having holding means passing through HENRY T PA 1STE' the holes of said pair of lugs, with a lamp Vitnesses: socket having its base confined between the WILLIAM E. BRADLEY, second pail` of lugs and the casing. Jos. H. KLEIN.
