UNITED STATES CHARLES H. I-IOFRIOHTER, F CLEVELAND, OHIO, ASSIGNOR TO THE CRESCENT BRASS PRODUCTS COMPANY, OF CLEVELAND, OHIO, A CORPORATION OF OHIO.

LIGHTING FIXTURE.

Application filed March 7, 1922.

To all whom it may concern:

Be it known that I, CHARLES H. Hormon- TER, a citizen of the United States, and a resident of Cleveland, county of Cuyahoga,

and State of Ohio, have invented a new and useful Improvement in Lighting Fixtures, of which the "following is a specification, the principle of the invention being herein explained, and the best mode in which I have contemplated applying that principle so as to distinguish it from other inventions.

The present invention relates to lighting fixtures having an adjustable socket, and more particularly, the invention relates to the means for adjusting the socket along the axis of the fixture and for readily and easily making such adjustment without disturbing the wiring, lamp or globe. To the accomplishment of the foregoing and related ends, said invention, then, consists of the means hereinafter fully described and particularly pointed out in the claims.

The annexed drawing and the following description set forth in detail certain mechanism embodying the invention, such disclosed means constituting, however, but one of. various mechanical forms in which the principle of the invention may be used.

In said annexed drawing Fig. 1 is an elevational view of the ad justing device with the reflector shown in section.

Fig. 2 is a section on line 2-2 of Fig. 1 with parts broken away and with parts shown in elevation.

Fig. 3 is a section on line 33 of Fig. 1.

Fig. 4 is a section on line 44 of Fig. 1.

As shown, the present fixture consists of a metallic'shell or shade-holding member 1 of general conical shape which is provided with an eye 2 for attachment to the ceiling or the like. A reflector or shade 1 is attached to the lower end of member 1, in any suitable manner and the upper end 3 of said member is flattened and has apertures 4 and 5 therein. Secured in apertures 4, which are two in member, are two rods 6 disposed parallel with the axis of the member which are held in place by means of nuts Serial No. 541,657.

7, these rods being diametrically opposite each other. Mounted within member 1 is a socket 9 of usual construction adapted to receive the lamp bulb 10, this socket being provided with two apertured ears 11 adapted to receive the rods 6 and act as guides for the socket.

In order to adjust the socket and thus the bulb, in and out with respect to member 1 and reflector 1*, a threaded adjusting screw 12 is mounted through the aperture 5 in the member, the screw having a knob 20 at its outer end by which it can easily be turned. This screw engages in an interiorly threaded block 13 formed on a strap 15 adapted to encircle the socket and clamped thereon by means of a screw 16 and nut 17 received in apertures 18 in the bent ends of the strap.

The position of the socket may readily be changed by turning the knob 20 which moves the block 13 in and out along the screw, the rods 6 acting as guides to hold the socket in alignment and against rotation, the position of the bulb relative to the member 1 or fixture and to any shade or globe which may be attached thereto being readily changed so that the light filament may be correctly positioned.

The construction is simple and inexpensive and may be readily assembled. The adjustment is simple and the parts are rela- 0 tively strong and unliable to breakage. A wide range of alignment may be made and thus bulbs of many types may be used with maximum efficiency from each.

Other modes of applying the principle of my invention may be employed instead of the one explained, change being made as regards the mechanism herein disclosed, provided the means stated by the following claim or the equivalent of such stated means be employed.

I therefore particularly point out and distinctively claim as my invention In a lighting fixture, the combination of a metallic holder adapted to carry the globe, D5 and provided at its upper end with a flat top having three apertures, guide rods rigidly mounted in two of such apertures and extending parallel to the axis of said holder, having a threaded aperture adapted to reathreaded adjusting screw rotatably mountceive said adjusting screw to move said ed in such third aperture and provided socket along said rods upon rotation of said 1 above said top with a knob, a lamp socket screw.

having two apertured ears slidably mounted Signed by me, this 15 day of February, on said rods, a removable band clamped 1922.
