Thi invention is directed to window shades and has application to shades made from any of the conventional materials, such as cloth or tion, with a portion of the marginal hem cut away to expose the interior of the hem and to better illustrate the arrangement of the fringe paper. The invention is particularly concerned tufts. with the problem of providing a shade which has Figure 2 is a sectional view along the line 2-2, a decorative fringe at the lower depending Figure 1. margin of the shade.

The formation of this tuft line can be acventional in the prior art, and associate the complished by hand, but the preferred method of fringe tufts directly with the fabric of the shade accomplishing it is y t e use Of a machine margin.

Other and further objects will be apparent from a description of the drawing, in which:

Figure 1 is a perspective View of a shade constructed in accordance with the present inven- 4 known as a chenille type sewing machine. This machine is conventionally used in the manufacture of chenille bed spreads and operates to thread a length of tufting cord in and out through the hem of the shade and the shade proper, simultaneously severing the cord at spaced points on one side only (in this case, the reverse side) of the fold. The result is a plurality of individual U-shaped tufts of equal length and regularly spaced which form a fringe when the severed ends are depended from the marginal edge of the shade. The appearance of the tufts after this machine operation i best hown in Figure 3.

After the tufts have been inserted as just described, the hem is then folded upwardly a second time along the tuft line 9, and subsequently stitched along the line 4 to the shade proper.

The details of the resulting structure are clearly shown in section in Figure 2. The first hem fold portion 1, which has a terminal edge 8 rearwardly of the tuft line, acts as a reenforcing elementfor the fringe and strengthens the hem proper, which also performs the additional function of receiving the shade reenforcing slat 5. This slat will normally rest on the upper or doubled portion of the individual tufts, as shown in Figure 3, and tends to some extent to maintain the tufts in position. The tufts, having been threaded through two thicknesses of the shade material, are also effectively maintained in position by frictional contact against the sides of the apertures formed in the material, by the sewing operation. If desired, they can be further reenforced by pasting an adhesive strip (not shown) along the tuft line 8, Figure 4. However, if the shade material is of conventional thickness and strength, further reenforcement should not be necessary.

, The simplicity of the construction will be evident from the fact that the complete fringe is,

in effect, formed by the single operation of forming the tuft line 9 in the manner just described, but the fringe which is formed is even more attractive in appearance than would be the case if the conventional fringe strip were simply attached to the shade, as such a strip gives the appearance of having been simply tacked. on; whereas the fringe of the invention appears as an integral element of the shade.

In the description of the shade as just set forth, the various steps of the method have also been recited. These may be summarized as the primary fold, the insertion of the tufts, the second fold along the tuft line, and the stitching of the hem. A feature of the shade is the formation of the tuft line through a double thick ness of shade material, so that when the hem is folded along this line, the tufts will be effectively reenforced. This has been found to be of importance particularly in the case of paper shades. In the case of cloth shades, it is not always necessary to reenforce the tuft line, and the method can be practiced by simply forming the tuft line, folding the extended margin upwardly along the tuft line to form a hem, and then securing the hem to the body of the shade by stitching or some other suitable way.

Having fully described my invention, I desire to be limited only by the ensuing claims:

1. In a window shade having a marginal hem, a decorative fringe formed on the depending margin of said hem, said fringe comprising a series of individual sections of decorative fibre, the ends of each section being inserted through spaced apertures in the hem margin and extending downwardly therefrom, said ends being spaced equidistant from one another and being of relatively equal length.

2. In a window shade, a marginal hem for receiving a reinforcing slat, said hem being formed from at least two thicknesses of shade material, and a decorative fringe depending from said hem, said decorative fringe being formed from a plurality of individual U-shaped tufts threaded through and supported by the double thickness of the hem.
