LAMP SHADE Filed March 5, 1926 Patented Apr. 8, 193% stars nonnn'r BEAnnsLnY, or onroaeo, rnrnvors LAMP straps Application filed March 5, 1926. Serial No. 92,628.

My invention relates to lamp shades and particularly to lamp shades adapted to be mounted upon lighting fixtures, or the equivalent.

5 The invention has among its other objects the production of lamp shades of the kind described, which are relatively inexpensive, convenient, durable and satisfactory for use wherever found applicable.

A particular object of the invention is to provide an improved device of the kind described, which can be quickly and easily mounted upon a lighting fixture, or the like, and readily removed therefrom.

Many other objects and advantages of the construction herein shown and described will be obvious to those skilled in the art from the disclosure herein given.

To this end my invention consists in the 20 novel construction, arrangement and combination of parts herein shown and described,

and more particularly pointed out in the claim.

In the drawing wherein like reference 535 characters indicate like or corresponding parts;

Figure 1 is a plan view of a lamp shade embodying the invention;

Figure 2 is a rear elevation of the improved 30 shade;

Figure 3 is a section taken on line 33 of Figure 2;

Figure 4 is a section taken on line 44 of Figure 1; and

Figure 5 is a section taken on line 55 of Figure 1.

In the drawing I have shown a preferred form of the invention embodied in a lamp shade adapted to be mounted upon lighting fixtures comprising incandescent lamps, or

the like, but it is to be understood that my invention is limited to this use only in so far as is defined in the appended claim. The illustrated embodiment of the invention-is particularly adapted to be used in connection with wall-brackets and fixtures of that type and preferably comprises an arcuate shade 10, or the equivalent, oi any suitable size and shape. In this instance, the shade 10 is 50 formed from paper or parchmentized material, but if desired, it may be formed from any other. suitable material.

Secured to the shade 10 is a cross-bar or bent; wire 12, which terminatesin a pair of integral eyes 14. Projecting, through the shade 10 and the eyes 14 are. tubular rivets 1-5, or the equivalents, for the purpose. As. shown, washers 17 of paper, leather, or any other suitable material may be positioned between the eyes 14 and the shade 10.

Carried; by the bent wire 12 intermediate its ends is a vertically disposed member or pin 18, which is preferably formed with an eye 19 at; its lower end to encircle the wire 12, the eye 19 being preferably soldered to the wire 12,215 indicated at 21. The member 18 may be oi any suitable size and: shape but is preferably formed from a flat strip of metal. Mounted upon the member 18 are clainping'members 23; and 24, the member 23 being preferably provided with slots 26 which conform to the shape of themember 18 and prevent the clamping member. 23 from being rotated around the longitudinal axis of the member 18. The clamping member 24 is preferably rotatably mounted upon the. member 18 and is. provided with circular openings 28 for this purpose. It will be noted that the slots 26, and the circular openings 28 are formed in flangesf29 formed integral with the clamping, members 23 and 24. If desired, the lowermost flange 29 of the clamping member 23 may be soldered to the member 18 at the same time that the member 18 is soldered to the wire 12. To prevent accidental withdrawal of the clamping members 23 and 24 from the member 18, the member 18 is preferably provided with a head 31.

Disposed around the pin 18 is a helical spring 33, which has one of its ends bearing against the clamping member 23 and has the other of its ends bearing against the other ciamping member 24, the spring being so arranged that it tends to rotate the clamping member 24 in a counter-clockwise direction (Figure 1) around the longitudinal axis of the member 18.

The clamping members 23 and 24 are provided with arcuate portions 34 and 35, respeclively, adapted to clamp around the lighting fixture 37 indicated in dotted lines in Figures 2 and 3, the clamping members being provided with finger-pieces or extensions 38, whereby they may be manipulated.

In practice, the improved device may be quickly positioned upon the fixture by displacing the finger-piece 38 of the clamping member 24- toward the finger-piece 38 of the clamping member 23 until the arcuate portions 34 and 35 may be slipped over the fixture, whereupon the finger-pieces 38 may be released and the spring 33 permitted to urge the arcuate portions against the fiXtur Of course, if the shade is to be removed from the fixture it is only necessary to release the clamping members from the fixture against the action of the spring 33.

Having thus described my invention, it is wbvious that various immaterial modifications may be made in the same Without departing from the spirit of my invention; hence I do not wish to be understood as limiting myself to the exact form, construction, arrangement and combination of parts here- Eu shown and described, or uses mentioned.

vi hat I claim as new and desire to secure by Letters Patent is:

In a device of the class described, the combination of a shade, a clamping means for securing said shade in place, an upright with which said securing means is attached, a cross bar to which said upright is connected, said cross bar being bent intermediate its ends to F provide supporting arms, the upright being connected to the cross bar atthe bend and projecting in the same direction as said arms, the extremity of each arm being connected rith opposite sides of the shade, said upright providing a pivot for an element of the clamping means and providing means for holding one of the elements of the clamping means against movement relatively to the other, and said upright being arranged transversely to said clamping elements.

In testimony whereof, I have hereunto signed my name.

ROBERT BEARDSLEY.
