To all whom it may concern.'

. Be it known that I, DANIEL C. GIDLEY,

of Albany, in the county of Albany and State of New York, have invented a certain new and useful Electric-Conduit Fitting, of

which the following is a specification.

' 'My invention has for its object the production of lan eljectric conduit fitting by y which the electrical appliance `supported j thereby can be adjusted axially and easily adapted to different conditions and thicknesses` of Walls concealing Athe conduit' workz-and it consists in the 'combinations and constructions hereinafter set forth and claimed. j In describing this invention, reference is hadl to the accompanying drawing in which like 'characters' designate corresponding parts in all the views.'

Figure l-is an elevation, partly' broken away,l of a preferable embodiment of my invention, the contiguous portions of the wall in which the fitting is embedded being also shown in section. Fig. 2 is a top plan of this fitting, partly broken away, and

. and havinga' flat bottom 2 and an opening 3 in its wall opposite the bottom, and also one or more internally threaded nipples 4 adapted to be connected to the conduits which inclose the electric wires.

4The opening 3 i's closed by a cap comprising inner Aandy outer telescoping sleeve members 5;, 6, one being fixed to the body 1 and the other being adjustable axially of the fixed member. In this embodiment of my invention, the outer sleeve member is fixed and the inner member adjustable, and

the outer member is provided with an external annular `iiange 7 which rests upon the margin 8. of the wall of the body around the opening 3, and is 'secured thereto by screws 9 extending through said iiange and into lugs 10 provided on said margin 8. v Usually, the outer edge of the marginl 8 isformed with an inwardly extending lip 11 which engages the inner face of the fiange 7, and the flange 7 is formed with a lip.12

Vat its outer v'edge which engages the outer face of ,the margin 8. This mode of connecting the body and the outer sleeve member forms a tight joint, and [dispenses with the necessity of machine inishing'liat surfaces of the iange 7 and wall 8.

The adjustable inner sleeve member 6 is held in its adjusted position by clamping means, as screws 13, extending through spiral slots 14 formed in the outer sleeve member, the screws 13 threading into the inner sleeve member. Obviously, by loosening the screws 13 and turning the inner sleeve member, the screws'will pass along the slots from high to low points thereof, or vice versa, and thus arrange the inner sleeve member either farther into or out of the outer sleeve member. The outer sleeve member 5 may be provided with butone of -these slots, but-in order to more iirmly support the inner sleevemembcr 6, the outer member 5 is usually provided with three of such slots. The inner sleeve member 6 is also provided with an inturned flange 15 at its outer end for a purpose to be presently explained.

- 16 is a socket for an electrical appliance, as a lamp7 said socket extending into the inner sleeve member 6 and having terminals 17, 18 at its inner endfor connection with the wires within the body. The socket is also provided with the usual central and l' sleeve terminals which engage the terminals' 90 of the electrical appliance.

The cap is constructed to receive sockets of standard makes and sizes and all of such sockets usually are provided at their outer ends with exterior annular flanges, as the flange 19, which laps upon the inturned iiange 15 of the inner sleeve member 6 and is secured thereto by screws 20. The periphery of this flange is of less diameter than the interior of the outer sleeve member 5Aso that it may, if necessary extend partly within said outer sleeve member.

In some instances, especially in concrete buildings, the conduits and fittings are embedded in the walls, as illustrated in Fig. 1, and the distances vary at which the conduits and the bodies of the ittings are located below the surface of the walls, and in use, by adjusting the inner sleeve member axivarranged close-to the plane of the outer In Concrete walls, the sleeve (i is adjusted to come flush with, -or in proper relation to, the shorings which confine the concrete until it hai-dens.

Although niy invention is particularly applicable for use in 'connection with concealed conduit work, obviously-conditions may arise in which it may be uscdbadvanl tageously in exposed or other forms of work.

What I claim is` 1. In an electrical appliance, the combination with a hollow body having an opening in one side thereof and a bearing sur-e face on the outer face ofthe margin of 4the wall around said opening, the extreme'edge of said margin being turned outwardly forming a lip, a ,sleeve arranged coaxially with said. 'opening and provided with a base flange overlying said margin and having an overturned edge resting on said bearing surface, the lip on said margin projectf f l of said margin being,r turned outwardlyl forming a lip, a sleeve arranged coaxially with said opening` and provided with. abase fiange overlying said margin and having an overturned edge resting on said bearing surface, the lip on said margin projecting to` ward said liange, means for attaching said ange to the side of the body, a second sleeve adjustably supported within the former sleeve, and an electrical appliance carried by the lsecond sleeve, substantially as and for'the purpose sp cified.

In testimony whereof, I have hereunto signed myname, in, the presence of two attesting witnesses, at Syracuse, ini the county of Onondaga and State of New York, this 5th day of October, 1910.
