April 3, 1945. H. DENT TAPE FOR USE IN MANUFACTURE OF LAMP SHADES Original Filed March 28, 1941 INVENTOR. fzrberi flea/ZZZ Patented Apr. 3, 1945 UNITED I TAPE FOR USE; IN MANUFACTURE OF' LAMP SHADES Herbert Dent, Chicago, Ill.

Original application March 28, 1941, Serial No. 385,587, now Patent No. 2,316,568, dated April 13, 1943. Divided and this application March 25, 1943, Serial No. 480,459

3 Claims.

This invention has to do with the manufacture of lamp shades of the type in which a covering of pleated or plain material is attached to an openwork frame, and is particularly concerned with the manner in which the covering is attached to the frame.

The primary object of the invention is to provide a special tape of unique character which can be used very eifectively to attach the covering to the frame. Use of the tape, in comparison with the laborious hand methods heretofore employed, not only gives much better results but materially cuts down the labor required and very greatly reduces the cost of producing such lamp shades.

While the foregoing statement is indicative in a general way of the nature of the invention, other more specific objects and advantages will be apparent to those skilled in the art upon a full understanding of the nature of the new tape and the way in which it is employed.

This application is a division of my copending application Serial No. 385,587 which was filed March 28, 1941, and issued April 13, 1943, as United States Patent No. 2,316,568.

A preferred embodiment of the invention is presented herein by wayof exemplification, but it will of course be appreciated that the invention is susceptible of incorporation in other modifled forms coming equally within the scope of the appended claims.

In the accompanying drawing:

Fig. 1 is a View in side elevation of a co'm pleted lamp shade utilizing the tape of the invention;

Fig. 2 is a side view of the special tape, showing a portion of the covering of the lamp shade sewed thereto;

Fig. 3 is a sectional view taken on the line 33 of Fig. 1; and

Fig. 4 is a corresponding section showing the covering and lining before being secured by sectape intermediate the side edges of the latter,

and the free edge of the tape is then bent over and secured to the frame member. The other edge of the covering may be similarly connected to the opposite marginal member of the frame by being sewed to another piece of the tape. The same method may be used for attaching the lining material, and an ornamental strip of braid or other trim material maybe attached around the frame to give a neat and pleasing appearance.

The reinforced tape may include a strip of cloth l0, which is preferably cut on the bias to give it a stretchable resilient quality. It is shown as reinforced by a bendable wire support l2. As disclosed this support or reinforcement consists of a wire continuously looped about a predetermined Width of cloth material throughout its length, as indicated in Fig. 2. Of course, this might instead be a wire netting, screening or other reinforcing means suitably attached to the material Ill.

One edge of a covering M is adapted to be attached to the tape intermediate the width of the latter, as at [6, whereby preferably to leave projecting portion'lB of the tape, as shown in Figs. 2 and 4. The other edge of the covering may be similarly treated. The projecting portion I8 is then bent backwardly and downwardly over a member 20 of the frame of the shade into a. substantially permanent hooked position thereover, whereby to hold the covering it to the member 20. No further securing means is necessary.

As will be noted with reference to Figs. 3 and 4, a lining 22 may also be secured at one edge to an intermediate portion of another piece of the reinforced tape, as at 24, and the joined material bent outwardly o-ver the inwardly bent portion l8 of the cover assembly as indicated in Fig. 3. For the purpose of giving a pleasing appearance and to conceal any rough edges, an ornamental strip or band 28 is then secured to the bent over portion of the liner or to the cover M or both.

Both the cover I l and the lining 22 may be readily attached to the reinforced tape by sewing. Various changes and modifications will be apparent to those skilled in the art upon an understanding of this embodiment of the invention.

I claim:

1. A cover attaching tape foruse in the manufacture of lamp shades, comprising a stretchable strip of cloth cut on the bias, and a wire support, said wire support consisting of a fine wire which is continuously and progressively looped flatwise about and against the strip of cloth in substantially the plane of the latter, the wire reinforced strip of cloth being longitudinally foldable and being resiliently stretchable in the direction of its length.

2. A rigidified tape for use in the manufacture of lamp shades, for attaching the cover to the frame of the lamp shade, comprising a thin flat stretchable strip of cloth out on the bias, and an openwork metal stiffener carried by the strip in substantially the plane of the latter and characterized by longitudinally spaced integrally connected portions which are positioned against the opposite faces of the strip and extend in directions generally crosswise of the strip, said tape being resiliently stretchable in the direction of its length and being bendable longitudinally of itself to provide a hooked connection for attaching the cover to the frame.

3. A special cover attaching tape for use in the manufacture of lamp shades, comprising a thin flat strip of soft pliant material, and a wire reinforcement associated flatwise with the strip to rigidity the same, said wire reinforcement having integrally connected portions positioned against the opposite faces of the strip, and said tape being bendable longitudinally into a substantially U- shaped position, whereby to constitute of the same a longitudinally continuous hook.-
