Patented June 10, 1930 Y UNITED STATES HOWARD LE ROY JENKINS, or NEWARK, OHIO, ASSIGNQB TO HOLOPHANE coMrANY, v 1 me, or NEW YORK, N. r, A CORPORATION or NEW YORK v SHADE surron-r Application filed October 11,1928. Serial No. 311,739.

The present invention relates to shade supports and .is more particularlydirectedtoward the type of shade support suitable for supporting heavy shades and reflectors about incandescent lamps ofvarious sizes with the shade and/orrefiector in the proper position to direct the light rays in the desired manner. V V

The present invention contemplates a gm shade holder particularly for the above'mentioned purposes wherein-the shade is supported at the lower end of a rigid frame which converges toward a central support such as a sleeve surrounding the pipe or 115 other support for the'lamp socket.

An object of-the present invention is to provide ashade holder having a' frame made out of bent wire members. whose lower ends are spread apart and adapted to receive the- 2250 rim of the reflector or shade andwhose up" per ends are carried inside. a s'lidable casing and bent to-a shape" such that they are immovable relative to one-another orthe casing. '25 A further object of the invention is to provide a shade holder having a frame.

made out of strongcomparatively stiff but somewhat resilient wire members secured at the upper ends to a slidable sleeve so that an" the shade may be removed from the shade holder and the holder and shade adjusted to the proper elevation relative tothe light source.

Other and further objects will appear :35: as the description proceeds. I I

The accompanying drawings show, for

purposes of illustrating the present invention, two of the many possible embodiments in which it may take form, it being undertaken on an enlarged scale and on the line. Y ,5D.22 of Figure 3; r

Figures i and 5 are elevational views of the upper portion of one of the frame mem bers; and.

fied form of construction. r

In the form of construction illustrated Flgure 6 1s a sectional VleW of a :mod1- in the drawings, the shade or reflector is indicated at 10. The :light source such as an incandescent lamp bulb is indicated at 11. This is carried in the usual lamp socket 12 carried in the lower end of the stem or pipe 13 adapted to be suspended from a loop or othersu-pport, indicated at 14:. Inasmuch as the unit may employ lamps 11 of varying,

desired light distribution- The construction,

to be described is especially suitable for supporting the reflector or shade in any desired position relative to the lamp source.

As hereshown, the lower rim 15 of the reflector or shade 10 is caught into tong-like hooks 16 carried at the lower ends of three frame members 17 These frame'members are preferably in the form of heavy stiff pieces of wire bent into the desired shape. These wire frame members are provided with the hooks 16 which are bent-inwardly as indicated at 1-8 to bring them near the reflector or shade and then bent outwardly' as indicated at 19 so as to clear the shade or reflector. They then converge upwardly and inwardly so that their upper ends are adjacent the socket supporting pipe or .tube 13. The upper ends of the frame members are secured in a sleeve designated generally by the reference character 20.

' The preferred construction of the sleeve is indicated more in detail in Figures 2 and 3, and the upper ends of the wire frame members are indicated in Figures 4 and 5; The sleeve 20 consists of two heavy strong cup-shaped- stampings 21 and 22 and a tube 23 adapted to'receive and cooperate with the upper hook-shaped ends of the frame V members. .As indicated in-the drawings,

sizes'and the reflectors 10 may have different. I

characteristic, it is desirable to be able to mount the reflector in the desired position the frame members 17 are bent at 24 so that a portion 25 of the frame members extends up parallel with the axis of the unit. The wire is then bent to provide another parallel portion 26 which extends down alongside the vertical portion 25. These parallel parts of the bent wire are connected by a portion 27 which is bent outwardly so that it may lie around the outside of the tube 23. The lower sleeve 21 is provided with notches '28 adapted to receive the wire frame members 17.

In assembling the shade support, the three frame members constituting what may be conveniently termed a tripod are passed into the respective notches 28 so that the portions 25 and '26 are carried above the lower flange 29 of the stamping 21. The end or tip 30 of the wire frame member 17 rests on the upper surface of theflange 29. The tube 23 may then be passed down inside the three frame members. In the preferred form of construction, the portions 24:, 25 and 26 of these wire frame members are shaped so as to lie close to the tube 23. The upper stamping 22 may then be passed down outside the upper portions of the frame members so as to bring the upper flange 32 of the stamping 22 against the extreme top of the frame members. The stamping 21 is provided with a larger diameter portion indicated at 33 which is adapted to receive the la'rgediameter portion 34: of the stamping 22. After the parts have been brought together as described, the upper edge 35 of the lower stamping 21 is rolled over against the shoulder 36 on the upper stamping so as to securely bind together the three frame members and the sleeve parts 21, 22 and 23. It will be noted that the shape given the parts is such that the arms cannot move relative to the sleeve. They are securely anchored in place.

The tube 23 is made slightly larger in diameter than the pipe 13 which supports the lamp socket and locking screws 37 and 38 are threaded through'the sleeve members and adapted to mount the shade support in the desired position along the socket supporting pipe 13. In order to hinder unauthorized adjustment of the mounting height of the shade, screws 37 and 38v are preferably made headless and are provided with socket wrench receiving openings 39.

The shade frame is sufiiciently resilient to 7 permit spreading the lower ends of the arms sufficiently to receive the shade or reflectors or permit their removal. In order to prevent accidental removal of the shade or reflector, the unit is preferably provided with a band 40 adapted to pass about the lower portions of the frame as indicated. Thisband is provided with a contractile spring 41 and with 'humps 42 adapted to receive the portions 18. of the frame. members. Owing to the shape and configuration of the parts, this band is securely held in position about the lower end or mouth of the reflector.

In the modified form of construction shown in Figure 6, the sleeve consists of an inner tubular member 51 with outwardly flanged ends 52 and 53, and an outer tube 54. The shade supporting arms 55 extend up through slots 56 in the lower flange and have outwardly bent tips 57 which pass through slots 58 in the upper part of the outer tube In assembling this form of sleeve the parts are put together and the upper flange forced over into position. The arms are held immovable in the casing with the advantages above set forth.

It is obvious that the invention may be embodied in many forms and constructions within the scope of the claims, and I wish it to be understood that the particular forms shown are but two of the many forms. Various modifications and changes being possible, I do not otherwise limit myself inv any way with respect thereto.
