Claims.

My invention relates to slide fastened articles and more particularly to articles wherein the material. bordering .ithe opening extends over the fastener to conceal it.

In several articles where it has been attempted to use slide fasteners, particularly articles of clothing which encircle a member of the body, and are under more or less side tension, a problem has appeared in attempting to have the edges of material bordering the slit cover the slide fastener. The side pull 'on thematerial will tend to cause the covering edges to'flare upwardly and expose the fastenerelements. This is especially true in such articles as spats, where the slit ficlin a rather sharply curved portion of the ar- The primary object of my invention is to solve the above problem in a simple and effective manner. I have discovered that if there are two rows of stitches attaching each side of the slide fastener to the" adjacent material and the material of the article iscrowded, between the rows of stitches to cause it to bow upwardly, :then all of the stress in actual use will come on the rows of stitches most remote from the free edges of the material, and the free edges will tend to hug closely against the fastenerelements rather than flare upwardly to expose the fastener elements.

In the accompanying drawing I have shown for purposes of illustration one embodiment which my invention may assume in practice. In the drawing;

Fig. 1 shows a spat embodying my invention;

Fig. 2 is a detailed cross-section through the spat on line 2-2 of Fig. l with the stringers under tension; and

Fig. 3 is. a corresponding cross-sectional view showing what happens in the conventional construction. The spat designated 4 is fitted over a shoe 5.. It may be shown with a decorative false row of buttons t, and the opening is in the form of a slit I in the center of the instep portion. A slide fastener. generally designated 8 is applied underneath the flaps. v

.The fastener stringers or tapes 9', I. carrying interlocking elements H on their adjacent edges are secured to the respective sides of the opening or slit I by a plurality of rows of securing means preferably by lines of stitching l2 and Il. The lines of stitching on either sides ofthe opening are spaced apart a suitable distance in parallel relationship to theedges of the opening. The inner lines of stitching it are spaced inwardly or the material a distance from the edge of the 1938, Serial No. 196,42!

opening on either side to provide fastener element covering flaps formed by the free edges l4 and --I5, respectively, which extend into meeting relation to cover the fastener elements. As shown in Fig. 2, the inner lines of stitching i2 and outer lines of stitching l3 join the fastener stringers to the article but in such a manner that the width of the tape between these rows or lines of stitching is less than the width of the flexible material between the same rows or lines of stitching. By positioning the rows or lines of stitching in this manner all lateral forces acting upon the sides of the fastener stringers will be taken up entirely by the inner lines or rows of stitching l2 and not by the outer lines or rows of stitching l3. Under this condition the stitches l2 assume an angular position with relation to their normal position while the stitches 13 remain in their normal position. Because any lateral force is thus prevented from pullingon the lines of stitching l3,-all tendency for the fastener element covering flaps to flare up is eliminated. The entire widthof the article material between the two rows of stitchingis bowed upwardly as indicated at I8. It will be understood that the material of the spat or similar garment l6 will ordinarily be relatively thick and soft. I When downward pressure comes upon the flaps l4, l5 they will bear against the corners of the fastener elements which willimpress themselves .to some extent in the soft material and allow the edges-of these flaps to curve downwardly against the fastener elements on account of the downward pressure upon them.

This will be true regardless of whether the fastener is under strain or not because the fullness or curvature in the portions It will prevent any tension being transmitted to the row of sitchi'ng It, thus causing the normal compression of the fabric in these portions to continue to act and hold the flaps l4 l5 inplace.

struction as shown in Fig. 3, the width of the tape and the width of the material between the lines of stitching l1 and I8 is equal and consequently any lateral force acting on the line of stitching II will be equally transmitted to the line of stitching ll. Because of this condition,

both lines of stitching will assume an angular position with relation to their normal position and will tend to displace the cover flaps l9 and II, respectively, and cause them to flare up and expose the fastener elements. It 'will thus be seen in contra-distinction to the condition described in Fig. 2 that when the construction of Fig. 3 is placed under tension the edges I. II

. 40 By way of contrast in the conventional conwill tend to be turned upwardly so that there will not be any pressure of the flaps against the corners of the fastener elements. This is due to the fact that the upper surface of the soft material will shift sideways more than the lower surface-so that the flaps tend to curve in the opposite direction from that shown in Fig. 2.

While I have shown and described in this application, one embodimentwhich this invention may assume in practice, it will be understood that this embodiment is merely for'the purposes of illustration and description and that various other forms may be devised within the scope of my invention as set forth in the appended claims.

What I claim as my invention is: 1. An article of the class described including a portion of flexible material, a slit in said flexible material, and a slide fastener for closing the slit,,

said slide fastener being positioned under the edges of the material bordering the slit, and consisting of a pair of tapes with interlocking elements on their adjacent edges, and a plurality of rowsof securing means for attaching each of the tapes to the flexible material of the article adjacent thereto, the width of the tape between said rows being less than the width of the flexible material.

2. An article of the class described including a portion of flexible material, a slit in said flexible material and a slide fastener for closing the slit, said slide fastener consisting of a pair of tapes with interlocking elements on their adjacent edges, said fastener tapes being positioned under the edges of the material bordering the slit, and a plurality of rows of stitching for attaching each of the tapes to the flexible material of the article, the width of the tapes between said rows being less than the width of the flexible material and the free edges of the flexible material extending beyond the rows of stitching into substantially meeting relationship to cover the interlocking elements.

3. An article of the class described including a portion of flexible material, a slit in said flexible material, and a'slide fastener for closing the slit,

said slide fastener consisting of a of tapes ,with interlocking elements on their adjacent edges, each fastener tape being secured under the edges of the material bordering the slit by two rows of stitches, one row being positioned inwardly from the edge of the slit and parallel thereto, the second row being positioned adjacent the inner edge of each fastenertape, the free edgesof the flexible material extending outwardly on each side of theslit to cover-the fastener elements, and the width of the tape between the rows' of stitching on each side of the slit being less than the width of the article material between the stitches.

4. The combination with a slide fastener having a pair of stringers of flexible material and rows of interlocking elements attached to their adjacent edges, of strips of material overlying the slide fastener and meeting in the longitudithe article, a slide fastener for closing the slit comprising two tapes with rows of' interlocking elements on their adjacent edges, the material of the article which borders the slit serving to cover, and conceal the entire fastener and two rows of stitching for securing each'tape of the slide fastener to the adjacent covering material, the width of the covering material between the stitches being greater than the width of the tape whereby the covering material is not bowed upwardly when under tension thus not lifting the free extending edges of the covering material away from the fastener elements.
