Specification forming part of Letters Patent No. 39,658, dated August 25, 1863; acted-ated vMarch 1, 1863.
To all whom it may concern:
Be it known that 1, 1t. H. Jnwn'r'r, of Versailles, in the county ot' Brown and StateV ot' Illinois, have invented a new and Improved Stitch for Sewing-Machines; and Ido'hereby declare that the following is a full, clean-and exact description of the same, reference being had to the accompanying drawings, forming part of this specification, in which- Figure 1 exhibits the structure of the stitch as exhibited by cutting the cloth in the line of the sewing. Figs. 2 and 3 are vertical sections, at right. angles to each other, of a machine for making my improved stitch. Fig. 4 is a plan ot the principal workin g parts ofvlthe machinef as exhibited by removing a portion ot' the bedplate. Fig. 5 is a-side view of the parts of the machine bywhich the threads are interlaced to produce the stitch. Y
Similar letters ot' reference indicate corre sponding parts in the several figures.
This invention consists in a stitch ot' novel character, producedwith two threads by passing one thread through'the cloth or other ma` teralto he sewed from one side thereof in a se ries of loops, and enchaining the other thread on the opposite side ofthe said material in a series of loops in such manner that each of the latter passes through one of the protruding loops ot' the iirst thread and receives the succeeding loop of its own series in a' manner hereinafter more fully described, such stitch being very strong and possessing' great elasticity.
To illustrate the structure of the stitch, I have represented the two threads of which it is composed-the one inblack outline and the other in red-i-n Fig. 1. To explain the process by which it is made, I have numbered the loops ot' each thread l 2 3, Src., in the order in which they are formed, and will speak ofthe thread which passes through the cloth, represented in black outline, as the upper thread, and ot the other one, represented in red outline, as the under thread. The stitch is commenced by passing a loop of the upper thread through the cloth, then passing through the said loop a loop ofthe under thread, nextpassing a second loop ofthe upper thread through the cloth, then passing a second loop of the under thread first through the first loop ofthe saine th read and afterward through the second loop of the upper thread, next passing a third loop ofthe upper thread through the cloth, and
then passing a third loop of .the under thread first through the second loop ot' the saine thread and afterward through the third loop of the upper thread, and so on indefinitely, passing every succeeding loop of the under thread first through the preceding loop of the same thread andafterwardthrough the corresponding loop vot" the upper thread, and so enchaining two ing the loops of the under thread.
In the machine represented the devices con sstof the eye-pointed performing-needle n for carrying the upper thread, working substantially like the perforating-needle of Iother sewing machines, the eye-pointed under needle, a, for carrying the under thread, and the looper b and loop-extender c.
The upperneedle, n, maybe applied and operat'ed asin other sewing-machines. It is represented as carried hy an arm, N, rigidly attached to a frame, N', which slides in Vertical guides N2 N2 under the bed-plate D, and is driven by a crank, N3, on the main shaft G, said crank working in a slot, it', in the said frame. It is supplied with thread (represent ed in red color) t'rom a spool, E,arranged on the bed-plate, and having applied to it a tension apparatus, E', which may be of any known or suitable construction'.
The under needle, c, is straight, and has a horizontal reciprocating motion below the bedplate, advancing as the upper needle is being withdrawn and retiring as the upper needle descends through the cloth. ried by a bar or slide, A, which derives motion from the frame N through a lever, A', link A2, lever A3, and rod A". Thread (represented in blue color) is supplied to this needle from a spool, H, under the bed-plate.
The looper b and loop-extender c are both pointed instruments, attached to separate bars or slides B and C, and work parallel with the under needle, a, below the bed-plate. These slides B and G derive motion' from the lever A3, to which they are connected by a T-shaped This needleis carslide, B. Thelooperb worksin a groove in the side of the needle a farther'from the line of mo tion of the upper needle, n, and its point is di- -rected the same Way as "the pointot' the needle a.
points being directed opposite ways, one is always advancing while the other is retiring.
The operation of the needles, looper b, and loop-extender c in forming the stitch is as follows: After the upper'needle, n, has passed a loop through the cloth, and while it is being withdrawn therefrom, the loop-extender c advvances intothe loop and extends it laterally, and by means of a shoulder, 10, formed upon it pushes it to a position for the needle a to enter and pass its eye through said needle a, having previously taken a loop ofthe under thread from the looper b. The needle t now has upon it a loop of each thread, and as these lie in a notch provided in the said needle back of its eye the looper b `passes them. The point of the looper moves over the needle a and behind its'eye, thus taking a loop of the under thread, onto which the other loops are dropped by the withdrawal of the needle a.
The feed mechanism may be the same as in other machines. That which is represented is a modification Vof the needle-feed, the needle n and all the stitch-makingdevices havinga hori* zon tal movement with the vibrating feed-plate I; but this needs no particular description, as it is not essential to the success of my invention. v
What I claim as my invention, and desire to secure by Letters Patent, is
The stitch produced-with two threads bypassing one thread through the cloth or other material to be sewed from one side thereof in a series of loops, and enchaining the other thread on the opposite side of' the said material in a sveries of loops in such manner that each of the latter passes through one of the protruding loops of the first thread and receives the succeeding loop ot' its own series, as herein specified.
