LAMP SHADE Filed March 4, 1932 INVE OR Patented Apr. 17, 1934 UNITED STATES PATENT OFFICE 3 Claims.

This invention relates to lamp shades and it has for one of its objects the provision of a structure by which a lamp shade may be economically, efiiciently and artistically made.

Other objects will be appreciated from a reading of the following specification.

Heretofore, in the manufacturing of lamp shades of a certain type, it has been the usual practice to employ two rings of wire, each of which has been joined at its ends, said rings being respectively connected to the top and bottom of the body of the shade or shade proper by means of adhesive tape. Such a structure is comparatively expensive and is unsatisfactory in providing a durable lamp shade. To overcome these objections, I have provided a lamp shade employing novel frames hereinafter described.

The invent-ion will be fully and comprehensively understood from a consideration of the 20 following detailed description when read in connection with the accompanying drawing which forms part of the application, with the understanding, however, that the improvement is capable of extended application and is not confined to the exact showing of the drawing nor to the precise construction described and, therefore, such changes and modifications may be made therefrom as do not affect the spirit of the invention nor exceed the scope thereof as expressed in the appended claims.

In the drawing:

Fig. 1 is a perspective view of a lamp shade made in accordance with one form of my invention.

Fig. 2 is a longitudinal section of the shade shown in Fig. 1.

Fig. 3 is a plan view of a blank employed in making the upper frame member of the shade shown in Fig. 1.

Fig. 4 is an enlarged fragmentary sectional view showing the attachment of a frame member to the shade proper; and

Fig. 5 is a fragmentary plan view of a modified form of a shade frame member.

Referring to the drawing for a more detailed description thereof, and at first to Figs. 1 to 4, inclusive, the numeral 7 indicates the body of the shade or the shade proper, said shade being clamped in upper and lower frame members 8 and 9, respectively, to hold the edges of the shade 7 together. The upper frame member 8 will now be described, the same being formed from a blank 10, shown in Fig. 3. Said blank is preferably stamped out of a fiat sheet of metal to form an inner ring 11, an outer ring 12, and radial strips 15 connecting said inner and outer rings, it being understood that said rings and strips are integrally formed with each other. The inner and outer rings are cut away or provided with notches adjoining the mentioned strips 15, as indicated by the numerals 16 so that said rings may be readily formed, the outer ring 12 into a channel cross-sectionally shown in Fig. 4 and the inner ring 11 into a tube. The radial strips 15 are reduced at their ends by providing notches l7 thereat so that said strips may readily be formed, as by stamping, into tubes. The outer ring 12, While of channel formation, comprises a flat inner side, and an outer side which is partly curved as at 19 and partly fiat at its marginal portion, as indicated by the numeral 20. The upper frame member 8, just described, has its outer ring clamped onto the upper end of the shade '7 proper, as well shown in Fig. 4. The lower frame member 9 is a ring formed from a single sheet of metal and has a cross-section similar to the outer ring 12 of the upper frame memher 8 and is clamped onto the lower end of the shade 7 proper. The frame member 9 is similar to the upper frame member 8 with the inner ring and radial strips of the latter omitted.

The form of my invention shown in Fig. 5 is adapted to form an upper frame member for a shade and comprises a ring 21 having a cross-section similar to that of the upper frame member 8,

which cross-section is shown in Fig. 4. ,The ring 21 is to be clamped to the upper end portion of a shade proper. A diametrical cross-sectionally channel-shaped bridge piece 22 is formed integral with the ring 21 and receives the ends of a single piece of wire 23, the intermediate portion of which is bent into a pair of opposed loops 24 and 25, adapted to be clamped onto a lamp.

What is claimed as new is:

1. A lamp shade frame comprising a one-piece ring and radial sockets formed integral therewith and a one-piece member bent into a pair of opposed loops and adapted to be supported by a lamp and having its end portions in said sockets.

2. A lamp shade frame comprising a one-piece ring and radial sockets formed integral therewith and means adapted to rest on a lamp and having its end portions in said sockets.

3. A lamp shade frame comprising a one-piece ring and radial sockets formed integral therewith and means adapted to rest on a lamp and having its end portions in said sockets, said ring portion being an inverted channel.
