Dec. 17, 1929. c. THEROUX SEAM FOR S EWED ARTICLES Filed Aug. 18, 1926 Patented Dec. 17, 1929 UNITED STATES PATENT OFFICE CHARLES TI-IEROUX, 0F BRUSSELS, BELGIUM, ASSIG-NOR TO UNION SPECIAL MACHINE COMPANY, OF CHICAGO, ILLINOIS, A CORPORATION OF ILLINOIS SEAM FOR SEWED ARTICLES Application filed August 18, 1926, Serial No. 129,963, and in' Germany April 19, 1926.

The invention relates to new and useful improvements in seams for sewed articles, and more particularly to a seam for joining fabric sections.

An object of the invention is to provide a seam for joining two sections of fabric which is formed by two threads, one above and the other below the fabrics, and wherein the thread above the fabrics extends in a single line along the edge of the fabric, and at intervals extends in a double line, and wherein said thread is formed into a series of loops penetrating the fabric, all of said loops on the under face of the fabric being brought to the line of the needle thread parallel with the edge of the fabric and secured by looper thread loops so that in the finished seam, there is, in effect, a straight line of interlocked chain stitches parallel with the edge of the fabric, and at intervals, a double line of thread leading along the upper face of the fabric at an angle to the line of stitches, then down through the fabric and back to the line of stitches.

A further object of the invention is to provide a seam of the above character wherein the fabrics'are so overlapped that the straight line of stitches will pass through only one of the fabrics, while the threads laid at an angle thereto extend through an overlapping layer of fabric and serve as the sole means for securing the fabrics together.

A still further object of the invention is to provide a seam of the above type wherein the fabric entered by the straight line of stitches is folded back upon itself so as to enclose a cord or reed, and the stitches serve to secure the folded portions of the fabric together.

In the drawings which show by way of illustration one embodiment of the invention- Figure 1 is a plan view of the seam embodying the improvements;

Fig. 2 is a sectional view on the line 2-2 of Fig. 1; I

Fig. 3 is a bottom plan view of the seam on a very much enlarged scale, and

Fig. 4 is a perspective View of the upper thread with the loops formed therein on a very much enlarged scale.

The invention is directed broadly to a seam for sewed articles, and more particular ly to a seam for joining two fabric sections which overlap each other. In the preferred form of the invention, a cord such as a reed is placed in the folded section of'fabric, and the folded section of the fabric overlapped by another section of fabric such as a hat sweat. The folded section of the fabric is the covering for the reed. The hat sweat and the reed coveringare secured together by threads, one of which is preferably a needle thread and the other a looper thread. The needle thread is laid along the edge of the hat sweat in 'a single line and at the proper intervals is formed into loops which penetrate the covering'for the reed. At spaced intervals, the needle thread is laid .at an angle to the line of stitches ust referred to, and is formed into a loop which penetrates the hat sweat and the reed covering. Beneath the fabric sections, this loop is carried over to the lineof needle loops first referred to. All of the needle loops are locked by a looper. thread loop which is formedinto loops passed through the needle loops and secured by succeeding needle loops in the well known manner.

Referring. more in detail to the drawings, I have shown a hat sweat 1. which is secured to a reed covering 2. This reed covering .2 is folded back so as to enclose the reed 3. The sections of the material are secured together by two threads, a needle thread 4 and a looper thread 5*. The needle thread 4- is formed into a series'ofloops 6, 7 8 and 9 as shown in Fig. 4:. These loops pass through the reed covering only, and are disposed at the edge and in a line parallel with the edge of the hat sweat. It will be noted that; there is, in effect, a straight line of single thread parallel with the edge of the hat sweat. 1. This is the needle thread 4: extending between the needle thread loops just referred to. The needle thread 4 is laid at an angle to the edge of the hat sweat as indicated at 10 and 11. This needlethread isformed into a thread loop 12 which is passed down through the fabric at the points 13, 13, respectively. The necdle thread loop 12 beneath the fabric is carried over to a point where it is in line with the needle thread loops 6, 7 and 9. The looper thread loop 5 is formed into loops 1% which are passed through the respective needle thread loops beneath the fabric. This looper thread loop 14, for example, passes through a needle thread loop 6, and the loop in the looper thread is secured by the next formed needle thread loop 7. A loop of thread 14; passes through this needle thread loop 7 and is secured by the needle thread loop 8. This is the usual manner of forming a double chain stitch.

From the above it will be apparent that a seam is provided wherein there is, in effect, a row of double chain stitches along the edge of overlapped fabric sections, and these stitches penetrate only one of the fabric sections. The other fabric section is secured thereto by thread loops alone which are projected laterally from the line of stitches and pass through the section of fabric which is secured thereto. It will be understood, of course, that the laterally projected loops may be formed at any desired intervals rather than at every other feed interval as shown in the drawings. It will also be understood that the laterally projected loop may be at an acute angle to the line of stitches instead of as at right angles thereto as shown in the drawmgs.

While I have shown the seam as applied to the securing of a reed to a hat sweat, it is understood that itmay be used for other purposes.

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

Seam for sewed articles comprising a folded fabric section enclosing a cord, a sec- 0nd fabric section over-lapping said folded fabric section to a line adjacent the cord, and stitching threads for securing the fabric sections together, including a needle thread formed into a series of loops pentrating the fabric section in a line outside of, adjacent and parallel with the edge of the upper fabric section, said needle thread being carried at an angle to the edge of the fabric sections at intervals including a plurality of needle thread loop formations, and formed into a loop penetrating said second named fabric section at a distance back from the edge thereof, said last-named needle thread loop being carried beneath the fabric to the line of the first named needle thread loops, and looper thread loops enchained with said needle thread loops in succession and disposed in a line parallel with the edge of the edge of the fabric sections.

In testimony whereof, I affix my signature.

CHARLES TI-IEROUX.
