Application June 14, 1933. Serial. No. 675,654

4 Claims.

The object of the present invention is to provide a lamp shade of a novel form, attractive in appearance and inexpensive to manufacture, a characteristic of the shade being that it comprises a frame and a plurality of tapered covering sheets each sheet having at its lateral margins two sets ofapertures communicating with slits extending to the edge of the sheet, the covering sheets being applied by bending them in 1 curved formation to present their edges to a cylindrical horizontally positioned member of the frame, the edges then being pushed into the frame at the slits until the frame lies within the holes and the slits automatically close to hold the curved covering sheets in position.

The invention constitutes an improvement upon the patent to Burke,.No. 1,894,302 of January 17, 1933, no folding operations being required and the appearance of the shade being unique and highly ornamental; also, the tapered ends, being relatively small may be cut from waste stock and the sheets may be economically manufactured. I prefer that the covering units when assembled upon the frame be clipped as a body into hot parafiin or other adhesive material so that they will be adhered to each other as well as individually held upon the frame.

The invention will be described with reference to the accompanying drawing in which Fig. 1 is a plan view of the shade constructed in accordance with the invention. I

Fig. 2 is a side elevation thereof.

Fig. 3 is a horizontal section on the line 3--3,

Fig. 2, omitting the spacer strips.

Fig. 4 is a plan view of one of the covering sheets.

Fig. 5 is a longitudinal section on 5-5, Fig. 1.

Fig. 6 is an enlarged horizontal section on 40 the line 3-3, Fig. 2 after the covering sheets have been dipped and coated with adhesive material.

Referring to the drawing, I may employ a frame comprising a ring-like member 1 conthe line nected by rods 2 with a small ring-like member 3 adapted to be supported directly upon an electric lamp bulb or upon a part of the 'lamp standard in the customary manner. If desired,

ring 1 may be connected by rods with a lower ring 4 indicated in Figs. 2, 3 and 6.

When the covering members are to be held substantially vertical relatively to the frame, the lower frame member may be eliminated as will also be the case where the covering sheets are assembled in outwardly flared relationship in the manner shown in Fig. 2 and are heldin said position whilst being dipped in adhesive, and after the adhesive has hardened. In such case the lower ring will be unnecessary.

In Fig. 4,1 have shown one of the covering sheets 5 in its blanked out condition. The sheet is taperedand provided at its upper end with opposed holes 6 into which are projected slits 7 extending to the edges of the sheet. Similar holes and slits 8 and 9 are provided near the lower end of the covering sheet for application to ring 4.

In practice, sheet 5 is grasped by the operator and longitudinally curved so that the slits 7 and 9 will be in register with their respective horizontal frame rings 1 and 4. The sheet will then be moved inwardly, the rings entering their respective slits and finally passing into the holes, the slits being automatically closed by the tension of the paper or other material employed.

It will be understood that the material employed in the tapered covering sheet may be paper, stiffened cloth, celluloid, cellophane or like sheet material, preferably transparent. It may be plain, colored or bearing printed, stencilled or painted designs.

The width of the shade will ordinarily determine the degree of projection of the curved covering sheet from the holding ring or rings of the frame although in some cases the sheet 5 may be flattened at and from both sides of its longitudinal center and thence curved or bent toward the frame ring or rings. In other words, it is not required that the shape of the covering sheet 5 when applied to the frame be curved throughout.

When the curved sheets are applied to the frame, the entire body may be dipped into paraffin wax or other adhesive so that the wax or other adhesive will come into contact with the meeting edges of the curved covering sheets mounted on the frame and will cause the sheets to adhere to each other.

In Fig. 6, I have shown an inner covering of adhesive at 10 and an outer covering at 1011:. In said figure, I have also shown a folded strip 11 interposed between the covering sheets 5 to serve as a spacer, which spacer may be of material colored differently from the sheets 5 and hence serving as a decorative medium. The spacer strips are not essential however, and their primary purpose is decoration.

V It will be understood that various modifications may be made in the form and arrangement of the elements comprising the embodi- 110 ment illustrated in the drawing without departing from the spirit of the invention. For example, the shade may have vertical sides and be square, octagonal or other shape. It may have outwardly flared sides or be circular or flat-sided in form, and the covering sheets may be widely varied in shape.

Having described my invention, what I claim and desire to secure by Letters Patent is as follows:-

1. A lamp shade comprising a frame having a horizontally disposed rod-like supporting member and a plurality of covering sheets held upon said supporting member, each sheet being initially flat and having opposed holes adapted to receive said rod-like support and having slits projected from the holes to the edge of the sheet,

the sheet being bent so that the slits are brought into register with the rod and the rod moved through the slits into the holes.

2. A lamp shade constructed in accordance with claim 1 in which the covering sheets are separated by spacer strips mounted upon the rod.

3. A lamp shade constructed in accordance with claim 1 in which each covering sheet comprises a. normally fiat tapered member capable of curvature on both sides of a line extending longitudinally of the sheet.

4. A lampshade constructed in accordance with claim 1 in which the sheets are coated with an adhesive coating serving to mutually adhere the said covering sheets.
