COVERED SEAM FOR SEWED ARTICLES.

SPECIFICATION forming part of Letters Patent No. 703,966, dated July 1, 1902.

Application filed April 26, 1899. Serial No. 714,579. (No model.)

To ctZZ whom it may concern: I r

Be it known that I, CHESTER h/ICNEIL, a citi zen of the United-States, residing at Chicago, in the county of Cook, State of Illinois, have invented certain new and useful Improvements in Covered Seams for Sewed Articles, of which the followingfis a description, reference being had to the accompanying drawings, and to the letters and figures of refer- Io ence marked thereon.

My invention relates to an improvement in seams for sewed articles; and the object especially is to provide a covered scam in which two pieces of fabric are superposed and united by a row of stitching along the edge and then spread out flat, the raw edges being covered by other threads.

The invention consists of a new combination of fabric and threads whereby this cov- 2o ered seam is produced, this combinationconsisting of two pieces of fabric whose edges have been superposed and united by a row of straight stitches along the edges and then spread out fiat and parallel rows ofloops passed through the fabric on opposite sides of the line of the seam entering and emerging on the same side of the fabric and cross-- threads concatenating with said rows of loops. Furthermore, the invention consists in the 0 matters hereinafter described, and referred to in the appended claims.

The invention is illustrated in the accompanying drawings, in which- Figure 1 is a plan view showing a seam for 3 5 sewed articles constructed in accordance with my invention. Figs. 2 and 2 are side views of the stitch, the former showing a seam where the upper or needle threadsare passing entirelythrough the fabric, while in the 0 latter the material is of such thickness that the threads simply take into it. Fig. 3 is a plan view of the fabric upon the opposite side from that-shown in Fig. 1.

In the drawings, A represents two pieces of fabric whose edgeshave been first superposed and then united by a straight line of stitching a and then spread out flat, the raw edges thereof being marked 1).

B represents rows of loops passed through the fabrics upon opposite sides of the middle line of theseam, each loop entering on one side of the. fabric and emerging on the same side ahead of its point of entrance.

For example, as shown more particularly in Figs. 2 and 2, 1 represents the startingpoint,'the needle passing through the fabric and emerging at the point 2, forming the loop B. A cross-thread, :the startingpoint of which is illustrated at 3, is then passed through the needle-loops. Then the needles back out of the material when the machine feeds, the looping device retaining the needle loops around it, when the needles again enter the material, coming out at 4 and passing between the looper and its thread when the looper backs. out of the needle-loops of the previous stitch, thus leaving its own thread around the needles, the result of which is that the looper-thread is left around the needle-thread in the stitch succeedingthat' in which it was first carried through the needle-loops. These cross-threads form the large loops 0, and thus the stitch may be briefly described as consisting of the rowsof loops B passed through the fabric, the threadsthereof entering and 5 emerging from the same side and the crossthreads passing through the loops B and diagonally across the line of the seam around the second pair of loops B, back through the first set of loops B, then through the second set of loops B, and so on, giving to the stitch the appearance shown particularly in Fig. l

of the drawings and covering the raw edges of the fabric.

In Figs. 2 and 2 a seam is shown, in the former the upper or needle threads being represented as passing entirely through the fabric, while inthe latter the material is of such thickness that the threads simply take into it.

It will be understood that in the formation of this seam the body of the goods is crimped over a substantially V-sh'aped piece .on the throat-plate of a sewing-machine, a presser foot correspondingly grooved, on its under side cooperating therewith, the needles pass- 5 ing through the goods entering and emerging on the same face of the fabric, this being a common way of holdin g goods on blind-stitch machines, as illustrated, for example, in machine shown in application for Letters Patent thread for locking the loops upon the upper surface of the fabric at the point where they emerge therefrom substantiallyas described.

2. The herein-described covered seam for sewed articles, comprising the two pieces of fabric A arranged with their edges abutting and united by a line of stitching a and a row of loops passing into each fabric and out again upon the same face of the fabric in advance of the entering point, said rows being parallel with each other, whereby the loops lie in the direction of the length of the seam, and an interlocking cross-thread for locking the loops upon the upper surface of the fabric at the point where they emerge therefrom, substantially as described.

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