SEAM OF STITCHES FOR UNITING MATERIALS AT THEIR. ABUTTING EDGES.

Specification of Letters Patent.

Patented July 21, 1914.

Application filed April 14, 1909; Serial N 0. 489,856;

V The present invention relatesto a seam of stitches and more particularly to a seam of stitches for uniting materials at their abutting edges.

The object of the present invention is to devise a simple and durable seam of stitches which may he formed from a single thread to unite materials at their abutting edges:

Another object of the present invention is to provide a method of makingsuch stitch which may be practised either by hand 0 by machinery.

With these objects in viewthe present in vention consists of a seam of stitches and the; method of making the same, shown-in the 1 accompanying drawings and hereinafter described and more particularly defined in the claims.

ure 1 shows a seam of stitches formed in accordance with and embodying the present; invention and also illustrating the method of producing such seam; Fig. 2 is a similar view looking in the opposite direction from; Fig. 1; and Fig. 3 is a cross sectional view .on line 33, Fig. 1.

As shown in Figs. 1 and 2, the seam of stitches comprises a plurality of loops 1- passed through holes 2 in the materials, ad-l jacent their abutting edges in any suitable manner, the holes preferably being stag-- I side of the-materials and that upon which the single threadlies as the lower sideof the materials. The method of making the stitch consists in first forming a loop and passing it upwardlythr'ough'one of the materials. The next step consists in passing the free end of the threadbodily through the end of the loop, and then forming another loop and passing that upwardly through the other material; the free end of the-thread is then passed through the end of this loop. These operations may be repeat ed, loops being'formed and passed upwardly through first one material and then the other, each loo-p being locked by the free end of the threadwhich is passed through ent stitch double threads are seen upon what 1 is referred to as the upper side of the material instead of a single thread as in the old and well known stitch above referred to.

The stitch forming the subject of the present invention possesses many advantages, however, over the oldbaseball stitch. In

7 the first place, it is a lockedstitch so that, In the drawings which illustrate the pre-.

'ferred form of the present invention, Fig-f although thethread may break or" give way at one or more points, the seam as awhole will still hold effectively. Again, if the side of the seam having the double threads be-the exposed side which, of course, in a baseball would be the outside of the cover, the wearing qualities of the seam are greatly increased since there are two threads to take the wear instead of a single thread asin' the old stitch.

Where in the claims the word upwardly 'is used, -'it is to be understood simply as Having thus described the invention, what is claimed as new, is

1. In a seam of stitches for uniting materials at their abutting edges with a single thread the combination with the materials having abutting edges to be sewn, of loops of thread on one side of the materials arranged alternately first upon one material and then upon the other, and single threads connecting the loops on the opposite side of the materials, each single thread passing through the closed end of one of said loops, substantially as described.

2. In a seam of stitches for uniting materials at their abutting edges with a single thread the combination with the materials having abutting edges to be sewn, of loops of thread on one side of the materials extending to the abutting edges of the materials alternately first from one material and then from the other, and single threads on the opposite side of the materials extending across the abutting edges from one material to the other and connecting the alternate loops, each single thread passing through the closed end of one of said loops, substantially as described.

3. In a seam of stitches for uniting materials at their abutting edges the combination with the materials having abutting edges to be sewn, of a plurality of loops of thread, each loop of which is passed upwardly through a single one of a series of holes disposed in a single row in each of the respective materials adjacent to the abutting edges, extends along the surface of the material from said hole to the abutting edges and is held by thread passed through its closed end at the abutting edges, substantially as described.

4. In a seam of stitches for uniting ma terials at their abutting edges the combination with the materials having abutting edges to be sewn, of loops of thread passed upwardly through holes disposed in a single row in each of the respective materials adjacent to the abutting edges, extending along the upper surface of the materials from said holes to the abutting edges and secured by thread extending beneath the materials and passed through the closed ends of the loops at the abutting edges, substantially as described.

5. In a seam of stitches for uniting mation with the materials having abutting.

edges to be sewn, of loops of thread passed upwardly through holes disposed in a single row in each of the respective materials adjacent to the abutting edges, extending along the surface of the materials from said holes to the abutting edges and held by a thread from the other side of the materials passed through their closed ends at the abutting edges, substantially as described.

7. In a seam of stitches for uniting materials at their abutting edges the combination with the materials having abutting edges to be sewn, of loops of thread passed upwardly through a single series of holes in each of the pieces of materials located in staggered position with relation to each other adjacent to the abutting edges, extending along the surface of the materials from said holes to the abutting edges and held by a thread from the other side of the materials passed through their closed ends at the abutting edges, substantially as described.

8. In a seam of stitches for uniting materials at their abutting edges the combination with the materials having abutting edges to be sewn, of loops of thread passed upwardly through holes disposed in a single row in each of the respective materials adjacent to the abutting edges, extending along the surface of the materials from said holes to the abutting edges and held by single threads passed through their closed ends at the abutting edges, substantially as described.

In testimony whereof I afiix my signature,

in presence of two witnesses.
