To all whom it may concern:

Be itknown tliat we, CARL H. Bissau and CHAnLns B. GARLING, of Syracuse, in the county of Onondaga and State of New York,

have invented a certain new and useful Electrio-Conduit Fitting, of which t e following is a specification. I Y

Our'invention has'for its object the production of a particularly simple and efficient structure including an electric conduit fit ting, a globe. for an incandescent lamp sup ported by a .socket within the fitting, a

bodying our invention. Fig. 2 is an en larged elevation, partly in section, of parts of said device. Fig. '3 is a section on line 1 A, Fig. 1 Fig. 41 is an end view of the for the globe Fig. is a fragmentary view of the guard,and Fig. 6 1s a pers the eddy of the electric conduit fitting, 1 body having one or more outwardly existing-internally threaded nipples 2 for connection with conduits, not illustrated, which inclose electric wires. The body is usually cylindrical in general outline and formed with a flat bottom 3 and with an axially projecting cylindrical portion fl: open I at its end and forming an axial continuation ,of'the portion of the body provided with the nipples 2. Obviously, the body may be provided with any other suitable means instead.

of the nipples.2 for connecting said body to one or more conduits. The body is also formed with internal integral posts 5 projecting from the bottom 3 thereof toward the open end of the projecting portion 4,

these posts 5 being spaced apart and de signed to support an electrical appliance, as

a lamp and its socket, the latter being se-" cured to the posts 5 by screws turning in openings 6 in the ends thereof, and-the pro of said posts above the bottom 3 pro riding passages for wires between the electricalfapplianoe and said bot-tom 3. The

" ective view of the locking member for the portion 1 between-the end 'face chereof and projecting portion 4 of the, body 1 is provided with an internal threaded surface 7 extending from its outer end and terminating short of the inner end thereof, and is also provided with an internal annular flange or shoulder 8 located beyond the threaded surface 7, and with an external annular shoulder 9, usually formed by reducing the outer end of the projecting portion 4.

lO'is an elongated globe having a threaded end which turns in the projecting portion 4 of the body against a packing ring 11 inserted between the end of said globe 10 and the internal annular flange or shoulder 8. By reason of the packing ring, shoulder, and threaded connection, a vapor-tight joint is formed between the-body 1 and the globe 10.

A suitable guard forthe globe is provided, the same being here shown as comprising a supporting member or ring 12 mounted on or encircling the end of the projecting portion 1 of the body, and abutting against the external annular shoulder 9, and side members 13 depending from the member or ring 12. Preferably, the member or ring 1.2 is formed with outwardly extending perforated ears 14: of less thickness than the main part of thering, and the ends of the members 13 extend through and are riveted to the ears 14,.Fig. 5. The intermediate portions of the side members 13 are encircled by bands 15. suitably connected. thereto.

The supporting member or. ring 12 is se-. cured to the projecting portion 4 of the body 1 by means of a locking member 16 carried by the member or ring 12 and having an edge portion 17 thereof movable into a cir- 'cumferential groove 18 which-is formed in the periphery of the reduced end of said the shoulder 9 and is normally covered by the member or ring 12. Said locking member '16 is here shown aspivoted at 19 at one end between outwardly extending ears 20 on the member or ring 12, the edge portion 17 of the pivoted end of the member 16 be ingmovable through a hole 21 which is formed in the contiguous'portion of the ring and is normally alined with the groove 18 and projecting into the groove 18 when the locking member is in its operative position, and another edge portion 22 of saidpivoted end beinglocated opposite to but out of the groove 18,when the locking member-is, in its inoperative position. It .isthus. apparent 1 that the edge portions 17 and 22 of the locking member 16 are dissimilarly spaced from the axis of the pivot 19 for said member 16. Said locking member is formed arc-shape in order to conform to the curvature of the member or ring 12 when said locking member is in its operative position.

Inorder that the guard may not be re-. moved and the globe and electric appliance tampered with by unauthorized persons,

' means is provided for preventing the removal of said guard, and as here shown, the member or ring l2 and the locking member 16 are provided, respectively, with perforated- ears 23, 24, the openings or perforations of which are designed to be in alinement when the locking member 16 is in its p engaging said projecting portion below the shoulder, substantially as and for the purpose described. 7

2. The combination of an electrical fitting comprising a .hollow body for receiving electric wires, and a cylindrical portion formed with an external annular shoulder, the body also having means for supporting an electrical appliance, a globe supported by said cylindrical portion, a guard'for the globe including a ring encircling the cylindrical portion and coacting with the shoulder and a member pivoted to the ring and engaging the cylindrical portion below said shoulder, giulastantially as and for the purpose speci- 3. The combination of an electrical fitting comprising a hollow body for receiving electric wires, and a projecting portion formed with a groove in its external face, the body also having means for supporting an electrical appliance, a globe supported by said projecting portion, a guard for the globe ineluding a member mounted on the external face of said projecting portion, and a locking member carried by the first-mentioned 'member and movable relatively thereto into and out of the groove, substantially as and for the purpose described. 4. The combination of an electrical fitting comprising a hollow body for receiving electric wires, and a projecting portionformed with a groove in its external face, the body also having meansfor supporting an electrical appliance, a globe supportedby said projecting portion, a guard for the globe including a member mounted on the external face of said projecting portion, and

.a locking member having one end pivoted to the firstmentioned member and provided with edge portions dissimilarly spaced from the axis of the pivot of said end, one of said edge portions projecting into the groove when the locking member is in its operative position and the other of said edge portions being opposed to said groove and located out of the same when the locking member is in its inoperative-position, substantially as and for the purpose specified.

5. The combination of an electrical fitting comprising a hollow body for receiving electric wires, and a formed with a peripheral groove, the body also havin means for supporting an electrical appliance within the cylindrical portion, a globe supported by the cylindrical portion, a guard for the globe including a ring encircling the cylindrical ortion, and
