UNITED STATES PATENT strong- LAMP-SHADE HOLDER;

Specification of Letters Patent.

Patented Nov. 6, 1906.

Application filed April 26,1906. Serial No. 313,848-

object is to provide a simple and inexpensive shade-holder that can be quickly attached to the shade, of which it then practically forms a part, and so made that the whole may be easily fastened to the lampso'cke t without the aid of screw-driver or other tool and firmly held in place.

.Reference is to be had to the accompanying drawings, forming an essential part of this specification, in which similar characters of reference indicate corresponding parts in all the figures.

Figure 1 is a transverse section of my improved shade-holder. Fig. 2 is a plan view thereof. Fig. 3 is a sectional elevation of shade and shade-holder, with a portion of each removed to more clearly show the relation of the various parts to each other and to the lamp-socket. Fig. 4 is a transverse section of a clamp-ringwhich Isomet'imeslise in connection with my improved shade-holder. Fig. .5 is a plan view of the same. Fig. (3 is a transverse section of a clamp-ring, showing an alternative design; and Fig. 7 is a plan view thereof.

"The shade-holder is designed primarily for use with shades made of paper, cardboard, celluloid, silk, linen, or other flexible material; but it may be used also in connection with rigid shades, such as those made of tin or aluminium.

Referring to the drawings, Fig. 3, A is a shade of material indicated above, generally conical in shape, and jointed in a sloping line in any convenient manner or molded in one piece. The interior is preferably white and of a reflecting character, and the exterior of a darker color; but the shade may be of the same. color all through, or either sur l face may be of any desired color and character.

I represents a lamp-socket to which the shade A 1s attached by means of the shade holder (i.

L is the bulb of an incandescent electric lamp.

The holder as first made is of the shape shown in Fig. 1 and consistsof a beveled flange C the knurl C the body C, and the neck C in which is rolled the knurlC to engage with the bead B of the socket. The upper part of the neck (1 is turned outward to facilitate the operation of pushing the shade-holder onto the lamp-socket and also to prevent the clamp-ring D from being accidentally displaced. The holder has a central opening C to permit of its engaging the lamp-socket, In the body of the holder C, between the neck C and the knurl C holes C are provided, and from them slots C preferably four in number, extend through the .neck, thus making it flexible and allowingthe neck to expand sufficiently to permit the knurl C to engage the bead B of the lampsocket. The holes C also afl'ord ventilation for the air heated by the lamp to escape, and to further facilitate this action additional holes, as C", are provided.v

The essential feature of my invention is the method of attaching the holder to the shade, which operation is accomplished in the following manner: The holder 0 is laced upon a suitable form. and the shade sipped 'over it, resting on the beveled flange C Pressure is then applied to the body of the holder, forcing the metal in the knurl C outward and downward, as indicated by dotted outline in Fig. 1, so as to envelop the upper edge of the/shade, as shown clearly in Fig. 3, and hold the shade firmly in place. The clan'ip-ring I) may then be slipped into its position on the neck, both it and the neck being flexible, or the holder may be attached of the clamp-ring, there being suflicient spring in the flexible neck to sustain the weight of an ordinary shade.

The clamp-ring D is made of spring-wire, preferably brass, bent into a circle of the proper diameter with the ends abutting and slightly apart, as shown at D. i

The clamp-ring E is chiefly used in cases where the upper edge of the neck of the in (3. It consists of two rings E and E joined by the piece E, which is bent to suit the bead. B of the socket. In this case the lower ring E prevents the upper ring F directly to the lamp-socket without thtYuseholder is straight and not turned outward, as

from passing up and off the neck of the holder.v

- It will be seen fro u'i'the drawings that the holder, with or without either of the clampri'ngs, may very readily be attached or detached'from the lamp-socket, all that is nectice I make them of thin metal, usually brass.

I do not claim any novelty for the body C, the central openin C, the neck C when made straight, the url C the ventilationholes C and C", the slots C or for the shade.

A as such.

Having now particularly described and asce'rtained the nature of my said invention and in what manner the same is to be performed, I declare that what I claim is 1. A shade-holder comprising a body having openings therein, a beaded neck having slots leading from. the' 'openings of the body ,out through the upper end thereof, a down- ,wardly and outwardly inclined annular flange adapted to fit within a shade, and asec- 0nd downwardly and outwardl inclined annular flange at the top of the rst flange for eeaaaa clanipin the upper edge of the shade, said second ange hem of double thickness and of less width than tie first flange.

2. A shade-holder, comprising a body, a neck, a downwardly and outwardly inclined annular flange adapted to fit within a shade, and a second downwardly and outwardly in 'clined annular flange for clamping the upper edge of the shade, said second flange being of double thickness and of less width than the first flange.

3. A shade holder, comprising a body formed with a neck and two downwardly and outwardly inclined annular flanges at its lower end between which the shade is clamped, the flanges being of unequal width and the narrower one being of double thickness.

4. A shade-holder, comprising abody hav ing a neck and provided with two downwardly and outwardly inclined annular flanges at its lower end between which the shade is clamped, the outer flange being narrower than the inner one.
