BEAM FOR SEWED ARTICLES.

Specification of Letters Patent.

Patented May 11, 1909.

Application filed July 7, 3995. Serial No. 268,663.

7 '0 all whom it may concern:

. Be it known that I, JOHN P. Wars, a citizen of the United States, residing in Nyack, county of Rock] and, and State of N ew- York, have invented a new and useful Improvement in Seams for Sewed Articles, of which the following is a description.

This invention relates to seams for sewed articles, and has special reference to seams which are made over the edge, or edges, of pieces of fabric.

Amon the objects of this invention may be note the following: to produce a seam. for sewed articles containing a plurality of threads forming an ornamental edging, selvage or finish for the work; to produce an edging for work composed of two needle or upper threads, and a single lower or lockin -thread; and to provide a seam which wi 1 be not only ornamental, but which will form a wearing edge for the ,work- With the above objects in view, my invention consists in the features andcom- In the drawings: Figure 1 isa perspective View showing the top surface of the work, the latter consisting of two pieces of fabric superposed and having their edges overstitched in accordance with my invenl tion; and Fig. 2 is a perspective view of the work of Fig. 1, but showing the bottom surfaceof the work.

Primarily, it should be understood that, although this scam is illustrated in connection with two pieces of superposed fabric, it may be applied to a single piece of fabric for the pur ose of giving to the latter a selvage or nished as well as ornamental edge, thus giving the same greater durability and increasing the wear of its edge, es-

eciall if the fabric be loosely woven or Referring to the drawings, 1 indicates the fabric, 2 indicates one of the top threads and 3 indicates the other of the top threads, while 4 indicates the locking-thread. The arrow 5 indicates the line of feed. The thread 2 is manipulated so as to form a singlle line of straight stitching on the top surface-of the work, the said thread being assed through the work from the top surace and formed into loops 2 at the bottom surface thereof. The thread 3 is also passed through the work from the top surface forming the loops 3 at the bottom surface of the 'work; but on the top surface of the work said thread 3 is carried over into the path of the loops of the thread 2, so as to surround the loops 2 at the point where the latter ass into the work at the top surface thereoi:

being indicated y 3", said loops being thus held by the straight line of stitching of the thread 2 on the topsurface of the work, as clearly shown in Fig. 1. A loop 4" of the locking-thread 4, is assed through both the loo s 2 and 3 of t e' respective threads 2 ant 3, extends from the bottom surface over theedge of the work and surrounds the loops 3* at the point where they pass into the work at the top surface thereof, said locking-loops 4 thus holding the said loops 2" and 3 closely united in pairs on the bottom surface of the work and being in turn held by the loops 3 on the top surface of the work, the said loop 4 extendin thus from the bottom surface of the wort across the edge and a distance over the top surface thereof. By thus manipulating the locking-thread, a, straight line of stitching of said thread occurs on the bottom surface of the work and loops of said thread are laid in parallelism over the edge of the work.

From the above description it will be seen that on the bottom surface of the work a straight line of stitching occurs which holds loops of the respective top threads in parallelism and a loop of one of said top threads grouped or paired with a loop of the other top thread, while on the top surface of the Work a line of straight stitchin occurs which holds loops of a top three which latter is iven a zigzag form and in turn holds the %oops of the lower thread. Obviously, the tension )laced upon either the top threads or the l ockingthread-will, in a measure, change the location of the several loops; that is to say, the loops of the to threads which are on the bottom surface. 0 the Work may be drawn, by tension on the locking-thread; into such position as to be located midway between the two surfaces of the work. instead of at the bottom ed e of the work, as shown in the figures, or t e bights of said loops may be located at any point between the point of enetration of thread 3 on the top surface 0 the work and the point where said loops emerge from the fabric on the bottom surface thereof, or the tension on the threads 2 and. 3 may draw tration of the loops 3", or to a position be- A tween the points of penetration of the loops of the threads 2 and 3, thus giving to the locking-thread on the bottom surface a zigza form. a a

i mong the advantages of this seam may be noted the followin An artificial selvage is roduced on the e ge of the work which wi 1 save the latter from wear and will give to the edge of the work a finished and or nate a peara'ncei-the edges of knit goods and 0t ier elasticfabrics can be prevented from inordinately stretching, pulling out or raveling; and an ornamental finish for the edges of work is produced.

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

1. A seam for sewed articles com risin the fabric and a plurality of threa 5 said seam being-characterized by having a thread forming a straight line of stitching on the top surface of t ie fabric, loops of a second thread 1 'ing on the top surface of the fabric and enchained with the thread of said line of stitching, and loo )3 of a third thread extending over the edge of the fabric and enchained with the loops of the second thread on the top surface of the fabric, and with loops of said first two mentioned threads below the top surface of the fabric.

2. A seam for sewed articles com rising the fabric and a pluralit Y of three s, said seam being characterize by having two threads enchained on the to 1 surface of the work, one forming a line of straight stitching and the other laid in loops at an angle to said stitching, and having on the bottom surface of the work two independent sets of loops, the loops of one set being inclosed respectively by the strands of the loops of the other set, and both said sets of loops being joined to the top surface 100 s by other loops extendin across the edge 0 the fabric;

3. A seam or sewed articles com risin the fabric and a pluralit of thread sai seam being characterized y having two independent sets of loops on thebottom surface of the fabric and a straight line of stitching on the top surface of the fabric, the loops of the respective sets on the bottom surface of the fabric being arranged in pairs and one of each air mclosin the other, and said sets of oops being oined with the straight line of stitching on t e top surface of the fabric by two enchained 100 s which cover the edge and top surface of t e fabric.

4. A seam for sewed articles com risin" the fabric and a plurality of three 5, said seam bein characterized b having the loops of two in ependent threa 5 passed throu h the :work from one surface to the other, said 100 5 being joined in pairs and brought toget er at the same oint on the fabric by the. loop of a third thread assed therethrough and over the edge of tlie fabric, and a line of zigzag stitchin joining the said loops of the third thread and the loops of one of the said independent threads.

in testimony whereof I have hereunto signed my name in the presence of two subscribing witnesses.
