This invention relates to dress shields and more particularly to dress shield construction.

Prior to the instant invention dress shields have been manufactured by stitching together two crescent shaped pieces of waterproof sheet material along the concave margins thereof, applying a waterproof tape on the stitched margins, then stitching together two crescent shaped pieces of woven fabric along the concave margins thereof, then laying the woven fabric over the waterproof sheet material and hemstitching or binding the convex margins to form the finished shield. This prior construction is relatively expensive and requires the use of relatively skilled operators to produce a satisfactory product.

It is an object of the instant invention to teach the production of an efiicient novel dress shield which shall be relatively inexpensive to manufacture.

It is another object of the invention to teach a novel method of manufacturing dress shields.

It is a further object of the invention to provide a novel dress shield.

Other objects and the nature and advantages of the instant invention will be apparent from the following description taken in conjunction with the accompanying drawings, wherein:

Figure l is a plan view of the four crescent pieces which are elements of the dress shield in accordance with the invention, with the concave margins of the pieces stitched together to illustrate one stage of the dress shield manufacturing process;

Fig. 2 is a plan view illustrating a further step in the manufacturing process;

Fig. 3 is a plan view illustrating a further step in the manufacturing process;

Fig. 4. is a fragmentary sectional view taken along line AA of Fig. 3 and looking in the direction of the arrows; and

Fig. 5 is an exaggerated sectional view similar to the sectional view in Figure 4.

Referring to the drawings, the sheet material of which the dress shield is to be made is arranged on the cutting table in the following manner: first a layer of pyroxylin coated fabric ID with the coated side [0a thereof facing downwardly and the uncoated side lflb thereof facing upwardly; second a layer of pyroxylin coated fabric II with the coated side Ha thereof facing upwardly and the uncoated side lib thereof facing downwardly; third a layer of uncoated fabric [2; and fourth a layer of uncoated fabric l3.

The four layers of sheet material are then 2 simultaneously cut into crescent shape illustrated in Figure 1. This cutting step may be effected by a die so that each layer of the cut material will be identical in size and shape with the other three layers. Instead of cutting only four layers at one time, multiples of four layers may be simultaneously cut with unit of four layers arranged as shown in Figure 1 and as described above.

The four cut layers, shown in Fig. 1, are then stitched together at M adjacent the concave margins I5.

A reinforcing binding tape I6 of pyroxylin coated fabric having a coated side Mia and an uncoated side l6b is activated on the coated side [6a with a suitable activator such as butyl acetate or amyl acetate and then pressed over the margins |5 as shown in Figure 2 in a manner to cover the stitching M, the pressure being sufficient to effect a flat neat binding, a waterproof joint at the stitching l4 and wherever the coated side [6a of the tape I6 contacts the layers l0, ll, [2, and I3.

As shown in Figures 3, 4 and 5, the two outer layers I0 and I3 are then folded back on themselves. The two inner layers II and I2 are then bound together at their convex margins I! by the binding stitching H3. The two outer layers In and [3 are also bound together at their convex margins in a similar manner by binding stitching not shown to form the finished shield. If desired the finished shield may then be pressed to form a neat effective dress shield of tailored appearance with the reinforcing tape I6 completely hidden from view.

Though the elements H), II, and I6 have been described as being made of pyroxylin coated fabric, it is to be understood that equivalent waterproof sheeting such as rubber, plastic or the like may be substituted and that a suitable cement or equivalent sealing and/or actuating agent may be substituted for the butyl or amyl acetate.

It will be obvious to those skilled in the art that various changes may be made without de-'- parting from the spirit of the invention and therefore the invention is not limited to what is shown in the drawings and described in the specification, but only as indicated in the appended claim.

I claim:

The process of manufacturing a dress shield comprising: arranging a first layer of waterproof sheeting on a cutting table, arranging a second layer of waterproof sheeting over the first layer,

arranging a third layer of sheet material over the second layer, arranging a fourth layer of sheet material over the third layer, cutting the four layers simultaneously into the general shape of a crescent, stitching the four layers together along their concave margins, applying a waterproof binding to the outside of the stitched concave margins of the four layers and sealing the stitching at said concave margins and sealing the binding to the concave margins of the inner 10 2,336,940 and outer layers and the concave marginal edges of the four layers, then folding back the two outer layers and binding their convex margins together, binding the convex edges of the 'two inner layers together.
