LAM P-SHAD'E HOLDER.

SPECIFICATION forming part of Letters Patent No. 411,107, dated September 17, 1889.

Application filedDecember 23, 1887. Serial No. 258,823. (No model.)

, To aZZ whom it may concern.-

' It is well known that shades for electric and shade-holder detached from the lamp.

other lamps are not commonly made in a mold, but are shaped as nearly as possible to the same dimensions without molding. The result of this is that scarcely any two shades are of exactly the same size at the rim, where they are usually attached to the shade-holder.

The object of the present invention is to make an adjustable shade holder, so that within certain limits it can be adjusted to fit shades of different sizes.

I have illustrated my invention in the accompanying drawings, in which- Figure 1 is an elevation of an incandescent lamp socket and shade with my shade-holder attached. Fig. 2 is a perspective view of my Fig. 3 is a plan showing a modification of myinvention.

Referring to the drawings by letter, A is an ordinary incandescent electric lamp, and Bis the lamp-socket C is the lamp-shade, and D is my shade-holder for supporting it. The parts A, B, and C are of the usual kind and form no part of the present invention. I have simply adapted the lamp-socket B to use with my present shade-holder by forming a groove 2) around it.

For connecting my shade-holder with the lamp-socket I provide a spring-ring E, which is open at e and provided with lugs f f, through which a screw passes for closing the ring more or less tightly around the socket. From this ring extend arms G G to make connection with a larger open ring H. Two of the arms G G are arranged on opposite sides of the opening in the ring H, and are fluted, corrugated, or notched, as shown, for a purpose that will be presently described. Upon the two arms last referred to a' slide I is adapted to move. V

The operation of adjusting the holder to a shade is accomplished by moving the slide I to its highest position and then inserting the rim of the shade in the ring H, which has sprung open to receive it. Then by shaking the slide downward or moving it down with the'fingers, or by simply pressing the lower ring together wit-h the fingers, the slide will be moved down and holds the ring tightly around the shade. Ordinarily it will be sufficient to close the ring around the shade and the slide will fall down of itself. If this should not be the case, it will move down upon being touched with the fingers. Owing to the corrugations in the arms G G the slide is held in place and also holds the ring in place under the rim of the shade.

It will be seen that my shad e-holder is adapted to be fitted to any shade within certain limits. The limits can be increased at will by widening the opening in the ring H and lengthening the slide, or, better, by changing the angle of the two corrugated arms.

The drawings show the opening in both rings located between the fluted arms. It is obvious, however, that it is only necessary that the opening in the ring which the arms control should be so-locat-ed.

It will be seen that one of the advantages of this holder is the facility with which it can be adjusted to a shade.

While I h. e only described, specifically, the shade-hold lng ring as being open in one place, I do not confine myself to that construction.

In Fig. 3 I have shown the lower ring in two sections-that is, open in two places-and the fluted arms placed at both openings in order to control both. By this construction I produce a holder which is adapted to fit a greater variety of sizes of shades. In ordinary use one of these openings may be kept locked at one position and "the other used in adjustment to the shade. This is optional, however.

I claim as my invention- 1. The combination, with a shade-holder for lamps, of a spring-ring for grasping the lamp,

a sprin g-rin g for grasping the shade, two fluted or corrugated arms connecting the two rings and located one on each side of the opening in the shade-ring, and a sliding catch, as and for the purpose described.

2. The combination, in a shade-holder for lamps, of two open spring-rings, one adapted to connect with the lamp and the other with the shade, secured together by a plurality of arms or braces, two of which are corrugated, fluted, or notched, and are located on opposite sides of the opening in the ring which supports the shade, the said fluted, corrugated, or notched arms being embraced by a sliding catch, which is adapted to hold the shade-rin g closed against its own spring force.
