SEWI FOR SEVVED ARTICLES.

SPECIFICATION forming part of Letters Patent No. 718,943, dated January 2C, 1903.

Application iiled February 18,1902. Serial No. 94,577. (No model.)

To all whom t may cm2/cern:

Be it known that I, EDWARD T. ALLAN, a citizen of the United States, residing at Cincinnati, in the county of I-Iamilton, State of 5 Ohio, have invented certain new and useful Improvements in Scams for Sewed Articles,Y of which the following is a description, reference being had to the accompanying drawings and to the letters of reference marked lo thereon.

My invention relates to an improvement in seams for sewed articles; and its object is to provide a novel bound seam for use on cloaks and the like in which two pieces of fabric are united and their raw edges bound all in one operation and by a single line of stitches.

The invention consists in the matters hereinafter described, and referred to in the appended claims.

In the accompanying drawings, which illustrate the invention, Figure lis a crosssection of the seam after its completion, but before itis pressed or iiattened out. Fig. 2 is a similar view showing it in process of being pressed or flattened. Fig. 3 is a similar View showing it after it has been pressed or flattened out; and Fig. 4: is a view similar to Fig. l, illustrating the mechanism-t'. e., folder and needlefor making the seam.

In the drawings, A A represent, respectively,npper and lower pieces of fabrics whose edges are superposed.

B is a binding-strip, which is herein shown in Figs. l, 2, and e as folded around the raw edges of the two pieces of fabric and having a hem fold a on each edge. The binding-strip B is provided with a central fold or crease I), which projects inwardly between the two edges of the material, keeping them sepa- 40 rated. The parts of the seam are held together by a single line of stitching c passing through both edges or hem folds of the binding-strip and through the two pieces of fabric, but not through the apex of the central fold or crease IJ of the binding-strip. It will be seen that by this arrangement when the seam is completed and ready to be ironed or otherwise pressed flat the central fold or crease in the binding-strip acts to separate 5o the two edges, so that they will not fold over wardly only so far as to properly separate the two pieces of fabric A A', and not so far as to cause the central fold or crease of the binding-strip to be engaged bythe needle d in its descent.

Other apparatus may be used for making the seam; but the above is simply mentioned as a convenient arrangement which has been devised for this purpose, and it will be understood that so long as the raw edges of the fabrics A A' are properly separated, so that in pressing the seam flat they will not fold in the same direction, but will turn in opposite directions, it may not be absolutely neoessary to form the central crease or fold I) in the binding-strip, it being sufcient, so long as the above result is accomplished, that the folding-guide accommodate a greater width of strip than is represented by the mere distance between its upper and lower edges and to make the binding-strip entirely cover the edges of the pieces of fabric to fold around said edges and to be secured by the line of stitching c.

Having thus described my invention, what I claim, and desire to secure by Letters Patent, is-

l. The herein-described seam for sewed articles, comprising fabrics having inwardly oppositely turned portions, and a binding-strip covering the upper faces, the edges and the lower faces of said inwardly-turned portions, and a line of stitching passing through the inner edges of the binding-strip and the two pieces of fabric; substantially as described.

2. The herein-described seam for sewed articles, comprising the fabrics having inwardly oppositely turned edges and a binding-strip having a body portion covering the said edges, and having its edges folded around the edges IOO tions of the fabrics and the bodies thereof, and provided with a hem fold on each side, and a line of stitching passing through the two pieces of fabric at the folds thereof, and through both thicknesses of the binding-strip at the hem fold; substantially as described.

In testimony whereof I affix my signature in presence of two witnesses.

EDWARD T. ALLAN.

having a body portion covering said edges, and folded around the edges of the fabrics and lying between the inwardly-turned porl Witnesses:
