LAMP-SHADE CONSTRUCTION.

Application led December, 21, 192B. Serial No. 156,200.

to an attaching strip which is providedwith means for attachment to the frame. In

this way the covers may be ,made up inv quantity at a factory and either sold individually for assembly by the customer or assembled at the factory upon frames, so that a semi-finished or finished article may be placed on the market.

:q Reference is made to my copending application Serial No. 147,349, filed November 9, 1926, on pleated fabrics for the' disclosure of a similar article, and in the description hereafter the present improvements will be described in connection with a similarly pleated cover made from alimp fabric, although it will be understood that the invention is not limited thereto.

On the accompanying drawings:

Figure 1 is a side elevation of a completed shade according to one illustrative form, with portions broken away to show the application of the invention thereto.

Fig. 2` is a developed view of a metal attaching strip according to this invention before application to a piece of fabric.

Fi 3 is a perspective view, showing the attac ing strip secured to a piece of pleated fabric, and having its own attaching means secured to a ring of a lamp shade skeleton frame.

Fi 4 is a view similar to Fig. 1 of a second illustrative form.

Fig. 5 is a detail view on a larger scale of the attachment strip of.y this second form attached to a cover.

Fig. 6 is a sectional View on a still larger scale, through the upper ring, showing the several elements in position.

According to the present invention, a skeleton Wire frame of the customary ty e is made up for the particular shade, thus efinin the major and minor bases and the lengt of side of the frame. It will particularly be understood that where reference is made, in the following specification and claims, to conical this is to be intended to include not only fully conical but also frusto-conical and pyramidal shades. The invention is not, however, limited to conical, frusto-conical or pyramidal shades, but may be applied for the general purpose of attachment of the edge of a piece of fabric to a support. The present improvements likewise concern means whereby a cover may be held in substantial condition for immediate and easy application to suoli a frame, and, as described in my aforesaid copending application, a limp fabric may be used for such 'a cover and stitlened by the means described herein so that the cover itself may be sold in condition for immediate attachment to a skeleton-frame.

According to this invention in the illustrative forms, a lamp shade skeleton frame is made up with the upper ring 1() and lower ring 11 which are connected and heldin rigid spaced relation by a plurality of reinlforcing bars 1Q. The shade cover 13 may be made of any suitable lmateriah but is illustrated as being formed of pleated fabric, which may be of limp material and formed into pleats in the manner described in my copending application prior to being secured to the present attaching devices.

According to the present invention, an attaching `device is provided which may be permanently secured to the said cover and which has tongue means for attaching the permanently associated cover and means to the several rings of the lamp shade. As shown in Fig. 2 the invention has been disclosed as employing a pliable metallic strip having a body portion 14 with laterally extending projections 15. The body portion has gashes 16 extending from the edge opposite the .projections across the width of the bod ortion and into the projection itself. his body portion may likewise be provided in the course of manufacturewith a series of apertures 17 extending longitudinally along the strip and may have the small tongues 18 formed therein by further gashes extending obliquely from the edge opposite' the projections, which may be called the free edge.

In making up a lamp shade according to the present invention the fabric 13- may have secured at its edge a paper strip 19, and the two materials be pleated and secured together by a stitched seam 20, as described in my copending application. The body portion 14 of the metal strip is then secured to the edge of this fabric cover 13 and to the paper reinforcement 19 thereof by a stitching 21 which passes through the apertures 17; or, as an alternative a sewing machine may be employed which itself will perforate the body portion 14 during the course of sewin as well as forming the stitches therein; this is old and well known in the art.

The cover may likewise receive a similar strip at its bottom and be placed on the market as a partly finished article. It is later associated with its proper frame by bending the projections 15 over to form hooks 15a, as shown in Fig. 3, whereby the cover is securely attached to the skeleton frame at the top. The cover is then drawn out along the lines of its generatrices and the similar hooks or other means provided at the bottom are then brought around the lower ring 11, care being taken to have the pleats directed along the line of the generatrices for the proper appearance. During the course of this securing of the hooks about the rings the upper metal strip will conform to the conical shape by the opening of the gashes 16, as shown at 16 in Fig. 3, and the fabricitself will yleld slightly for this purpose; and a similar conformation occurs at the lower strip. The

tongues 18 being opposite the narrow por-V tions of the body, i. e., those free from projections 15, may likewise permit a yielding or clamping for the same purpose, so that the strip assumes the substantially conical shape roper for the particular shade. After t e cover has thus been assembled upon the frame it is customary to place a lining and binding or edging braid 22 around the respective ring and edge of the shade where such may be engaged with the outwardly bent tongues 18 as described hereafter, and then this binding material may be fastened in place by a stitching seam 23.

According to the second illustrative form of Figs. 4, 5 and 6, thevpliable metal strip has a body portion 14 with the apertures 17 therein as before through which the stitching 21 passes to hold the pleated cover 13 permanently to this reinforcing strip after the cover has been assembled as set forth in my copending application, for example. This metallic strip body 14a has the integral laterally extending projections 15", and the spurs 18a are stamped out during the manufacture of the strip, being of triangular form with the altitude line of each triangle substantially coinciding, in the illustrated form, with the axis of symmetry of the respective projection 15x at which it is located.

This form of shade is assembled as follows: The cover 13 is fastened to the strip 19, pleated and secured by the stitching 20 as set forth in my copend'mg application,

for example. The metal strip 14, 15 is then laced at the edge of cover, at the outer face, a bias tape 30 is placed at the inner face, and the stitching 21 employed to connect these parts. The strip 14a and the tape 30 reinforce the material and distribute any strains, so that the stitches do not pull out.

An intermediate fabric lining 31 isprepared of conical form, with its sides projecting above and below the respective top and bottom frame rings, and is loosely positioned on this frame. The finish fabric lining 32 is likewise prepared of conical form, but, as shown by the dotted lines 32, is of lesser diameter than the shade at any plane at a right angle to the axis of the frame.

The cover strip, of segmental form owing to the shape of the pleats and by reason of the yielding of the metal strips as set forth above, is then a plied by bending the projections 15a of the respective strip over the upper ring, for example, to form hooks which engage over the intermediate lining 31 and hold this in place, as shown in Fig. 6. The spurs 16L have likewise been bent outward to form hooks, and the free edge 31u of the intermediate lining is folded back and engaged thereon. A similar` operation is then performed at the bottom ring 11,

whereby a roughly covered shade is produced.

tween these rings curves inward and then' upward of its own elastic strength.

An edge binding 35 is now prepared by doubling a suitable fabric to present a smooth edge 35u. placed upon the turned edge of the finish lining 32 and sewed by a stitch 40 thereto at a line'intermediate its width, but nearer' to the rough edges 35 than to the smooth edge 35a. This stitch has for distinctness been shown as full lines in Fig. 6, but it will be understood that it is preferably concealed. The smooth edge 35 has been kept toward the axis of the frame; the binding 35 is then folded over the stitching into the position of Fi 6 in which it hides the rough edges 35h, an is held b its own elasticity around the projecting ead formed about the ring by the thicknesses of material; or it may be secured by a concealed stitch. A. similar binding it then placed at the bottom of the shade.

In each illustrative form it will be noted rihis binding is thenY that the metal strip may be cut from a skel having a width equal to the combined wid of the projections and twice that of a body portion, since the saw-like projections 15, 15t are complementary of the ap between them. These strips can thus be c eaply and easily cut to shape, with their gashes and stampings, by a punch press or rolling mill.

It is apparent that the invention is not limited solely to the illustrative form represented, but that it may be employed in many ways in the arts.
