To all whom it may concern.

Be it known that l, JAMES S. CnossLnY, a citizen of the United States, and resident of Solvay, Onondaga county, State of New York, have invented certain new and useful Improvements in Shade-Holders, of which the following is a specification. This invention relates to shade and globe holders and the principal object is to pro- ,Figure 1 is a side elevation of a shade holder embodying my invention secured in place on, an electric lamp socket and supporting a shade. Fig. 2 1s a viewshowlng the shade holder in cross-section and showing in elevation the socket to which the ,shade holder is attached; and Fig. 3 is a detail cross-sectional view of one of the shade retaining screws and showing its connection all to the shade holder shell. 4

Referring to the drawing 10 designates a cylindrical socket shell substantially of uniform diameter from top to bottom except for an integral circumferentialexterior head 11 near the lower edge which is of greater outer diameter than the socket shell 10 above and below it. The usual cap 12 telescopica'lly fits over the upper end of the shell 10 and is securedthereto b screws 13 or other suitable means. The s ell 10 and cap 12 together form the casing for the usual electric lamp socket (not shown) which carries the incandescent lamp 14. v

The shade holder proper comprises a shell 15 provided at the upper end with a threaded neck 16, the upper edge of the neck being rolled upon itself inwardl as at 17 to provide a double thickness 0 metal at the upper end of the shell. The interior diameter of the upper end of the neck at' the pomt 17 is substantially the same as the exterior diameter of the socket shell 10 and the double thickness at the upper end holds that part of the neck at a distance equal to the-height of the head 11, the upper end 18 of the shade holder15 engaging against the lower side of the bead 11.

The device for clamping the edge 18 of the shade holder against the lower side 01 the head 11 comprises a returning ring 19 which has a portion 20 at the outer lower.- end thereof threaded to fit the threads on the neck 16' and the upper edge thereof is turned inwardly as at 21 and has a diameter substantially the same as the outer diameter of the-socket casing 10. The lower-side of the inturned edge 21 rests on the upper side of the beadll and when the threaded parts are interengaged with one another'the ring 19 clamps the upper edge of the shell 15 securely in place. A portion of the outer face of the ring 19 opposite the head 11 is knurled as at 22 to provide a better grip for turning the ring. 1

lVhen securing the shade holder shell 15 to the casing 10 the neck 16 is slipped over the lower end of the shell until the upper edge 18 of the neck abuts against the lower side of the bead 11 and the retaining ring 19 1s slipped over the upper end of the socket shell 10 and screwed onto the neck 16 until the parts are clamped to the supporting bead 11. It will be seen that the ring 19.

must be located on the shell 10 either before the wires are connected to the socket or before the shell 10is slipped overthe lamp socket and before the cap 12 is secured thereto, as it is not possible to slip the ring upwardly over the head 11' on account of the fact that the inturned flange 21 is smaller in diameter than the bead 11. The neck of the shade holder and the threaded connection between the shell and ring are entirely below the head 11. L

The shell 15 has a depending flange 23 to which the globe or shade 2a is attached.

bushings 28 fitted in holes 29 inthe flange 23. The holes 29 are located at the centers of outwardly pressed portions 30 of the flange 23. The depressed portions 30 are square or angular as shown in Fig. 2 to reroe ire

ceive the square or angular heads 'or flanges 31 on the inner ends of the bushings 28 so as to prevent the bushings from turning in the holes 29 when the screws 25 are turned. As shown the heads 31 are countersunk so that they will be flush with the interior wall of the flange 23. Th'ewasher 32 surrounds the bushing 28 and fits against the outer surface of the flange 23 and an outwardly turned flange 33 at the outer end of the bushing 28 holds the washer 32 and the bushing firmly in position in the hole 29.

The advantages of the construction will be apparent from the foregoing description and while the device has been shown in detail it is not intended to limit the invention as slight changes inthe device may be made without departing from the spirit of the invention.

Having thus described my invention what I claim and desire to secure by'Letters Patent is:

1. A shade holder comprising a shell provided with shade or globe engaging means and having a threaded neck, the end of said neck being adapted to. engage one side of a shade holder supporting bead integral with the lower end of a, socket shell, and a retain-' ing device having a threaded portion at one end capable of engaging said threaded neck shade holder supporting bead integral with the lower end of a socket shell, and a retain ing ring having a threaded portion at one end capable of engaging said threaded neck and provided with an inturned edge at the other end thereof capable of engaging, the upper side of said supporting bead to clamp said shell against the lower side of said supporting bead.

3. The combination of a socket shell having a supporting bead near the-lower end thereof, said bead providing a shoulder having an outer diameter greater than every part of the shell above it, a shade holder having means near its lower edge for engagmg a shade and provided with a threaded neck, the upper end of said neck engaging against the lower side of said head, and a retaining ring having an integral inwardly extending part of less inner diameter than the bead resting on said shoulder and a threaded portion capable of engaging said threaded neck to clamp the upper end of the neck against the lower side of said bead.

4. A shade holder comprising a shell pro- 5, vided with a depressed portion ,having a hole therein, an interiorly threaded bushing secured insaid hole and having a part disposed in the depressed portion of the shell, said depressed portion and the part of the bushing fitting therein being other than circularin shape, whereby the bushing is locked against turning in said hole, and a shade retaining screw fitting said bushing.

5. A shade holder comprising a shell provided with rectangular outwardly pressed parts near the lower edge thereof, said parts having holes therein, interiorly threaded bushings secured in said holes andvhaving rectangular flanges on the inner ends thereof locked against turning by the rectangular outwardy pressed parts in the wall'of said shell, and shade retaining thumb screws fitting said bushings.

6. A shade holder comprising a shell provided with shade or globe engaging means and having a threaded neck with a thickened edge, said thickened edge being adapted to engage against the lower side of a shade holder supporting bead integral with the lower end of a socket shell, so as to bring the exterior ofthe threaded portion of the neck substantially even with the outer edge of the supporting bead, and a one-piece retaining device having a threaded portion at one end capable of engaging said threaded neck and provided with aninturned edge at the other end thereof capable of engaging the upper side of said supporting bead to clamp said shell against the lower side of said supporting bead.

A shade holder comprising a shell provided with shade or globe engaging means and having a threaded neck, the upper edge of said neck being adapted to engage against the lower side of a shade holder supporting bead integral with a socket shell, and a onepiece continuous retaining ring having a threaded portion at one end capable of engaging said threaded neck and also provided with inwardly extending means at the other end thereof of less inner diameter than the bead for engagementagainst the upper side of said supporting bead to clamp said shell against the lower side of the bead.

In testimony whereof I afiix my signature.
