LIGHT FIXTURE.

Application filed May 7, 1926. Serial No. 107,430.

This invention relates to electric light fixtures and pertains particularly to an adjustable fixture.

The primary object of this invention is the provision, in a manner as hereinafter set forth, of an electric light fixture having an upright supporting standard and a normally horizontal light carrying arm fixed to the standard, with a novel securing and adjust ing means connecting the upright standard to the horizontal arm.

Another object of the invention is the provision, in a manner as hereinafter set forth, of an adjustable electric light fixture having a standard provided with means whereby the lower end thereof may be fixed in a T groove of a machine such as a lathe, or other machine of this type to enable the operator thereof to have light thrown directly upon the work.

A final object of the invention is the provision, in a manner as hereinafter set forth, of an adjustable electric light fixture which shall be strong 'and durable, easily and quickly adjusted to position, and comparatively inexpensive to manufacture and easily and quickly set up upon the desired location.

The invention will be best understood from a consideration of the following de-' tailed description taken in connection with the accompanying drawing forming a part of this specification, with the understanding that the invention is not confined to any strict conformity with the showing ofthe drawing but may be changed and modified so long as such changes and modifications mark no material departure from the salient features of the invention as expressed in the appended claims.

In the drawings:-

Figure 1 shows the device embodying this invention andsin side elevation.

Figure 2 is a top plan View of the fixture a portion thereof being shown in section to more clearly show the relation of the parts. Figure 3 is an enlarged detailed sectional view taken upon the line 3-3 of Figure 2 and, 4

Figure 1 shows in detailed perspective a portion of the standard clamping structure of the fixture. Y i

Referring now to the drawing indetail wherein like numerals of reference indicate corresponding parts throughout the several views, there is indicatedby the'numeral 1 a supporting means for the fixture which means may be a portion of a machine such as a lathe, Which is provided with a T shaped groove 2. The upright standard of the fixture is indicated by the numeral 3 and as is shown the lower end of this standard is threaded as at 4 and has upon this end a nut 5 which is adapted to be positioned in the groove 2 to engage therein as shown. Threaded upon the end of the standard 3 adjacent the nut portion 5 is a winged nut 6 which is threaded down against the top of the base portion 1 to secure the standard in the position shown.

Adjustably secured upon the standard 3 by the clamping structure indicated as a whole by the numeral 7, is a normally horizontal light carrying arm 8 provided at one end with a handle 9 and upon the other end with the incandescent lamp socket 10. This arm 8 is tubular and has an electric cord'll extended therethrough from the handle end to the socket end, by means of which current is supplied toan incandescent bulb12 positioned in the socket 10. Secured by means of the clamp 13 about the socket 10 is a shade or reflector 14, by means of which light fromthe bulb 12 can be directed to any desired point.

The securing clamp 7 comprise -as shown in Figure 3, an elongated U-shaped body legs 15 of the member have formed therethrough ali ned apertures 20.

Positioned within the U-shaped member is a plurality of aligned discs indicated by the numerals 21, 22, 23 and 24, respectively,

the disc 21 being rounded upon one side as shown, to fit the curvature of the yoke 16 and further being provided with a recess 25 corresponding to and aligning with the recess 18 in the yoke 16. The other side of the disc 21 has a transverse semi-circular groove 26 cut across the face thereof and further has a relatively shallow circular recess 27 formed in this face.

The disc 22 abutting the disc 21 has its abutting facef provided with a transverse semi-circulargroove 28 and further has extending outwardly from this face the circu- 7 mental ribs or recesses, as

of the abutting members of passages transversely lar lug 29 which is designed to fit into the recess 2? of the adjacent disc to maintain the two discs in alignment. The opposite face of the disc 22 is also provided with the outstanding lug 30 which fits in a corre sponding circular recess 31 formed in the abutting face of the disc 23. ,The other face of the disc 23 and the abutting face of the disc 2% are formed like the abutting faces of the discs 21 and 22, that is each with a transversely extending semi-circular recess and witha circular recess-and corresponding circular rib to hold the discs in alignment.

The outer face of'the disc 2% has a socket 32 formed therein to receive the end of the binding screw 33 which is threadably extended through the aperture 19 in the con.- necting bar 17 between the legs of the U- shaped member. While the recesses and lugs 21 and 22 and 23 and-2t, have been described as circular, it will be readily seen from reference to Figure l that afterthe formation of the semicircular grooves across the faces of these discs, these recesses and lugs take the form of diametrically oppositely positioned segthe case may be.

Threaded into the center of the curved side of the disc 21 is apin 3 1-. which extends a substantial distance beyond theside of the disc as shown and, when the discs are in aligned position as shown in Figure 2, this pin extends into the recess 18 in the yoke 16 of the U-shaped member and has positioned thereabout a spring 35 which is compressed when the binding screw 33 is forced inwardly to force the discs into close relation.

position as shown in Figure 3 they setup anelongated cylindrical body having a pair thereof formed by the joining together of the semi-circular groovesof the abutting faces of the discs.

The standard 3 is entendedthrough one ofv these apertures, betweenthelegs 15 ofthe U-SllELPECl member while the arm 8 is extended throughthe other one of the apertures, which aperture is formed between the discs 23 and 24k, and is also extended through the apertures 20 in the legs 15 of the U- shaped member. It will be readily seen that slightrotary movement of and between the discs may take place, which movement allows the arm 8 to be raised or lowered in an arc, and when the arm Sand standard 3 are in the proper relation the binding screw 33 may be screwed inwardly to forcethe discs'together and thu'shold the standard and arm in the clesired'relation.

Having thus described my invention what I claim is f 1. In a fixture of the character described, comprising apair of crossed members, a clamp for securing said members together, comprising a substantially U-shaped memher having a bar connecting the free ends of the legs thereof, a plurality of disc elements positioned side by side between said legs, the abutting faces of certain of the discs having semi-circular grooves formed thereacross setting up transverse apertures, each of said members being extended through an aperture, and a binding screw threaded through saidbar and bearing against the adjacent one of said discs to bind the discs together. i
