SEAM FOR SEWED ARTICLES Filed April 8, 1927 61cm 14 up Patented June 24, 1930 ATES r FFIE 'HAROLD J. LE VESCONTE, "OF CHICAGO,

ILLINOIS, ASSIG-NOR TO UNION SPECIAL SEAM FOR SEWED ARTICLES Application filed April 8,

The invention relates to new and useful improvements in seams for sewed articles, and more particularly to a flat covering seam for joining the edge portions of fabric sections.

[in object of the invention is to. provide a seam of the above character wherein the fabric sections are joined by interlocked thread loops passin through the edge portions while placed face to face, and alternately anchored in the alternate fabric sections at points back from the edge portions.

A further object of the invention is to provide a seam for sewed articles of the above character wherein the thread loops are anchored by passing into and out of the respective fabric sections on the same face thereof.

11 still further object of the invention is to provide a scam of the above character wherein the covering thread extends across the edges of the fabric sections covering the same, and is secured by the interlocked thread loops at their blind stitch connection with the fabric sections.

In the drawings which show by way of illustration one embodiment of the invention- Figure 1 is a plan view on a very much enlarged scale showing the improved seam, and showing in section the shaping of the fabric sections;

Fig. 2 is a plan view of the threads as they are arranged and interlocked in the finished article, and

Fig. 3 is a sectional view showing the manner of passing the needles through the fabric sections in the form of the seam.

The invention is directed to a flat covering scam for joining fabric sections. The two fabric sections have their edge portions placed face to face. The seam is preferably formed of three threads; two needle threads and a cross thread. The needle threads are formed into thread loops; The thread loops of one of the needles is first passed into and out of one fabric section only, back from the edge thereof, thus making a blind stitch connection therewith, and then through the edge portions of both fabric sections. A loop in ric sections.

1927. Serial No. 182,057.

the other needle thread is then passed into and out of the other fabric section only, back from the edge portion thereof, thus making a blind stitch connection therewith, and then through the needle loop of the first needle P and through the edge portions of the fabric sections. The following stitches are like the first two described. The loop in the needle thread always passes into and out of the fabric section, then through the loop of the edge portions a and Z) are placed face to face. Y

The threads for joining the fabric sections and making the flat seam are shown in Fig. 2. These threads consist of a needle thread 1,

a needle thread 2 and a cross thread 3. The

needle thread 1 is formed into needle thread loops 4, 4 and the needle thread 2 is formed into needle thread loops 5, 5. The needle thread 1 is carried by a needle 6. The needle passes the loop 4 into and out of the fabric section A at the crimped portion a therein. The needle then passes through the edge portions of the two fabric sections. The needle thread 2 is carried by a needle 7. This needle 7 first passes through the crimped portion (Z of the fabric section B, and thence through the needle thread loop 4, and then through the edge portions (1 and b of the fabric sections. On the first reciprocation of the needle 6, it will pass through the needle thread loop 5 where it emerges from the fabric section and before it passes the edge portions of the fab- The cross thread 3 is laid about the shank of the needle loop 4 where the needle loop 4 enters the fabric section A. The cross thread then extends over the edges of the fabric sections and about the shank of the needle loop 5 where it enters the fabric secon 13.

From the above it will be apparent that the needle thread loops all lie at the outer faces of the edge portions a and b. lVhen a lateral strain is placed on the scam, the anchored portions of the needle thread 1 pulling on the thread loops Will draw the edge portions of the fabric sections into closer contact. The needle thread loops 5 anchored in the other fabric section aid in drawing the edge portions of the fabric sections into close contact.

The seam is very elastic, very simple in construction, and the edges are Well covered.

It is obvious that minor changes in the details of construction may be made Without departing from the spirit of the invention as set forth in the appended claims.

Having thus described the invention, What I claim as neW and desire to secure by Letters Patent, is

1. A seam for sewed articles comprising fabric sections having the edge portions thereof placed face to face, a needle thread having a series ofthread loops, each of which passes into and out of one fabric section only and through the edge portions of the fabric sections, a second needle thread having a series of loops therein, each of Which passes into and out of the outer fabric section back from the edge portions thereof, and then through the edge portions, the loops in the needle threads being secured by the shank of a succeeding loop, and a cross thread passing about the shanks of the successive loops in both threads and crossing and covering the edges of the fabric sections.

2. A seam for sewed articles comprising fabric sections having the edge portions thereof turned out of the plane of the fabric sections and placed face. to face, series of thread loops associated With and anchored in each of said fabric sections, the loops of each of said series passing through the edge portions of both fabric sections and being locked by the loops of the other series.

3. A seam for sewed articles comprising fabric sections having the edge portions thereof placed face to face, a needle thread hav ing a series of thread loops each of which passes into and out of one fabric section only and also penetrates the edge portions of the fabric sections, a second needle thread having a series of thread loops therein each of Which passes into and out of the other fabric section only and also penetrates the edge portions of the fabric sections, the loops in the needle threads of one series being secured by the shanks of the loops in the other series.

In testimony whereof, I affix my signature.
