THREAD-AND CORD EDGE-FINISH FOR FABRICS.
SPECIFICATION tbrming part of Letters Eatent No. 726,311, dated. April 28, 1903.
Application filed October 2, 1901.
To all whom it Wmy concern:
Be it known that I, HERMANN A.'KLEMM, a citizen of the United States of America, and aresident of New York city, county and State of New York, have invented certain new and' useful Improvements in Thread-and- Cord Edge-Finishes for Fabrics, of which the following is a specification.
My improved edge-trimming for laces, knit goods, and other loosely-meshed fabrics consists of cords laid on the margins of the fabric near the edge, one or more on each side, and secured on one side of the fabric by donble-zigzag needle-threads and secured on the other side by a looper-thread inserted transversely of the seam through the loops of both lines of needle-threads and securing the needle-thread loops, one of the said lines of needle-thread loops being made along the edge of the fabric and together with the looperthread forming an improved edge-trimming and incidentally a binding to the edge of the fabric and the other line of needle-thread loops being made inside of the cords, as hereinafter specifically described, reference being made to the accompanying drawings, in which Figure l is a plan View of a short section of my improved edge-trimming formed in a straight line. Fig. 2 is an edge view of the same. Fig. 3 is a plan view of the same inverted. Fig. 4 is a transverse'section on line 4 4 of Fig. 1. Fig. 5 isaplan view of myimproved edge-trimming formed in scallops.
(t represents the fabric; b, a cord laid on the upper surface of the margin as near the edge as may be desired. 0 represents another cord similarly placed on the lower surface of the fabric.
(1 represents one of the zigzag needlethreads,and 2 represents the other of said zigzag needle-threads. These threads cross the cord Z) diagonally in reverse inclinations, and
thus cross each other on the cord and prac tically in the middle of the same, thus constituting a double-zigzag seam.
f represents the looper-thread, inserted through the loop of the needle-threads directly across from one line to the other of said loops under the fabric and over the cord 0, both directly and diagonally, and forming Serial No. 77 291- (No model.)
ragged edges of lace goods and the like which cannot be made with the single-zigzag thread.
Thus it will be seen that I provide very substantial ornamental edge-trimming, and incidentally a binding for fabrics of the character specified.
Although I have represented only one cord on each side of the fabric in the drawings, it is obvious that I may apply one or more on each side, as may be desired, and I include this in my claim.
It will be seen that my improved edge trimming. is especially adapted for substantial trimming for lace and other open-mesh goods by reason of one of the lines of needle-thread loops being made along the edge of the fabric and together with the looper-threads forming binding consisting of a chain of thread links in which there are in each stitch two loop members comprising one member of two needle-thread loops crossing said edge at a distance apart and a chain of looper-thread loops coupling said needle-threads along the edge, as shown in Fig. 2.
I am aware that in the patent to Stockton Borton, No. 640,085, of December 26, 1899, for improvements in ribbons or bands a sewing-machine having a vibrating needle to form what is commonly termed a zigzag stitch as a means of securing a cord on the margin of a band is incidentally referred to as a possible means for so securing the cord; but my claim is specific to double-zigzag stitches in which the threads of one line of stitches cross the threads of the other line of stitches intermediately of the two lines of stitches and intermediately of the stitches of the two lines.
I am also aware of the French patent to Sidgreaves, No. 103,232, dated April 29, 1874,
in which double-zigzag threads cross each other on the upper surface of the fabric and are secured on the under side by two lines of shuttle-stitches.
What I claim as my invention is Edge-trimming for laces, knit goods, and other loosely-meshed fabrics, consisting of the combination With the fabric of a cord or cords laid on the margin of each side of the fabric near the edge, the cord or cords of one side of the fabric being secured by doublezigzag needle-threads crossing each other and said cord or cords midway of the lines of needle-stitches and midway of the stitches of both lines, and the cord or cords on the other side of the fabric being secured by a looperthread inserted transversely of the lines of the needle-threads through the loops of both lines of said needle-threads and forming one directly-transverse line crossing said cord or cords and one diagonal line also crossing said the fabric and together with the looper-thread forming binding to said edge whereof the respective members of the edge line of needlethread loops cross said edge at a distance apart and more efiectually bind edges of open-mesh fabrics.
Signed at New York city this 14th day of September, 1901.
