. 1,449,65& M. F. DEACH.


CIWMMW Patented Mar. 27, 1923.



Application filed October 27, 1920, Serial No. 419,981. Renewed February 7, 1923.

To all whom it may concern:

Be it known. that 1, MILES F. DEACH, a citizen of the United States, residing at Oakland, in the county of Alameda and State of California, haveinvented certain new and useful Improvements in Electric- Lamp Fixtures, of which the following is a specification.

My invention is an improved electric lamp fixture.

Referring to the annexed drawing in which my invention is illustrated and which forms a part of this specification,

Figure 1 is an elevation of my fixture and an electric lamp mounted thereon.

Figure 2 is a view similar to Fig. 1 taken at right angles thereto.

' Figure 3 is a vertical section-of the fixture taken on line 31 3 of Figure 2.

Figure4 is a sectional view ofthe clamping rings taken -on line 44 of Figure 3.

Figure 5 is an inside view, of one of the clamping members. i

In the drawing, 1 indicates a base and 2 a cylindrical standard secured in said base. A sleeve 3 fits over the top of said standard, a portion 4 of the wall of the sleeve converging upwardly and resting on the top of the standard and supporting the sleeve at the proper elevation on the standard so that the sleeve may turn on the standard. The lower end 5 of the sleeve 3 converges inwardly into frictional engagement with the standard 2 to normally prevent turning of the sleeve on the standard and is slit upwardly at 6 in several places to allow the parts between the slits to yield so that the sleeve may be turned by the application of a little force thereto. The upper endof the sleeve 3 is split downwardly, forming two" ears 7 and 8 upstanding from the converging portion 4 of the sleeve, said ears'having central openings 9 and 10 to receive a screw 11, the head 12 of which engages the ear 8. A butterfly nut 13 screws on the screw 11 against the ear 7. A pair of clamping members 14 and 15 are interposed between the ears 7 and 8. The clamping member 14 comprises an end wall 16-provided with an opening 17 through which extends screw 11,

' and an annular flange 18 extending inwardly from said -end wall. The clamping member 15 comprises an end wall 20 provided with an opening 21 through which extends the screw 11 and an annular flange 22. extending inwardly from said end wall. The

flange 18 of clamping member 14 is pro.- vided with two semi-circular notches "25 and 26 in its inner edge'arranged opposite each other. The flange 22 of the clamping member 15 is provided with two semi-circular notches 27 and 28 in its inner edge arranged opposite each other so' as to register respectively with the notches 25 and 26. A tube 30 extends through the clamping members and26 and 28 tightly against the tube 30.

The lamp may be turned in a horizontalplane, the split lower end 5 of the tube 3' allowing the sleeve to turn on the standard 2. The tube 30 may be extended through the notches 25 and 27, and the lamp may alsobe rotated about said tubes.

Having described my invention, I claim:

1. A lamp fixture including a base, a standard mounted on said base, a' sleeve turnably mounted and resting freely on said standard, the lower endof said sleeve being split and converging into frictional engagement with said standard, a tube mounted on the upper end of said sleeve, and a lamp on the end of sald tube.

2. A lamp fixture including a base, a

standard mounted on said base, 'a sleeve turnably mounted on said standard, the wall of said sleeve converging upwardly and resting on the top of said standard to support the sleeve on the standard, a lamp and means for mounting said lamp on the upper end of said sleeve.

3. A lamp fixture including a base, a

The clamping members 14 and 15 ton standard on said base, a sleeve turnably mounted on said standard, a pair of upstanding ears formed integrally on the up-. per end of said sleeve, a pair of clamp members between said ears, a screw extending through said ears and said clamp members on which screw said clamp members are adapted to turn, a rod between said clamp members, the head o f said screw engaging the outside of one of said ears, and a butter: fly nut on the other end of said screw for said ears, each'clamp member including an end wall and an inturned annular flange in the inner edge of which flanges are registering notches, a rod extending between said clamp members, a lamp on said rod, a screw extending through said ears and the end walls of said clamp members on which screw said members may turn, the head of said screw engaging the outside of one ear, and a butterfly nut on the other end of said screw engaging the other ear to draw said ears against the end walls of said clamp members and the notches of said clamp members against said rod to clamp the lamp ,Zat any angle.

In testimony whereof I aflix my signa: ture.
