om this stationary" thread guide 9 said thread passes through a thread guide 10 on the upper end of the needle bar, and is thence led to a thread-guiding wire 11 on the arm-7, and from the threadiding wire to the thread-guiding eye 8. giiid threadam To all whom it may concern: 7

Be it known that I, VANDIVEI: J. -VAN HORN, a citizen of the United States, resid ing at Chicago, in the county of Cook, State of Illinois, have invented certain new and 0 Sewing-Machines, of which the following is a description, reference being had to the accompanying drawing and to the letters and figures of reference marked thereon. I

' The invention relates to new and useful improvements in ornamental stitch sewing l ng arm 7 is'so disposed as to reciprocate 1n the path between the needles 5 and 6, and from a position in front of said needles to a position in rear thereof. As herein shown,said thread arm 7 is carried by a short shaft mounted in a bracket 12. Saidv shaft is oscillated by means of an arm 13, 70 which is connected through the link 14 to an 7 arm 15, rigid on a sleeve 16. Said sleeve 16 may be oscillated by any suitable mechamsm.

Cooperating with the thread guiding arm 7 is a thread-manipulatin device 17, which,

ing application, Serial No. 373,069, filed- May 11th,1907. I

An object of the invention is to provide a dles with thread-manipulating devices for guiding an ornamental thread and 'forming therein loops, together with a presser foot, which is constructed so as to give suflicient room for the manipulation of the loop, and as herein shown, is forke at its lower end, to aid in guiding said loop so that the same and provided with thread-en ging hooks is entered by one of the needles. 18 and 19.

The presser provided with a thread-guiding eye 8 at its foot 23 is carried y the usual presser bar forward end, through which -an cm- 24, and "is provided with an opening to remental thread. Said thread is led from the eeive the needles. Said presser foot has a source of supply through a suitable rearwardly. projecting tongue 24, which 11s I An suitable stitch-forming mechanism may e-provide'd for ooiiperating with said needl The thread arm 7 is needle bar.

tapers downwardly towardthe lower surface of the presser foot. Said projecting tongue 24 divides the opening in the presser foot, forming needle slots 25 and 25. The needle slot 25 is cut away, so as to give considerable clearance on the outside of the needle 5. Said needle slot 25 is also slightly cutaway in front of the needle, and tapered downward as at 28, to a point near the bottom of the foot. The object of this construction of the needle slot 25 is to assist in positioning and guiding the loop in the ornamental thread formed by the hook 19. Inasmuch as the hook 19 carries both strands of the loop formed thereby, to the rear of the needle 5, when said hook is retracted, said loop is carried around the outside of said needle, which is at this time entering the fabric. The cut away portion 27 in the presser foot allows the loop in mental thread plenty of room, whereby it may be swung around to the outside of the needle without placin 'the'needle under any strain. The long hoo 19 serves also to retain the loop until it has been brought around in front of the needle, and when said loop is dropped from the hook 19, the curved, tapered, cut-away portion 28 will engage the neck of the loop and guide the same, so that the needle in its next descent will penetrate said loop, as shown in Fig. 8: In order to assist in the manipulation of the loop in the ornamental thread, I have also cut away or grooved the presser footon its under side in the rear of the needle. opening 25, as shown at 29, Fig. 7, and alsoas shown in dotted lines in Fig. 6. This cut away portion of the under side of the foot, 'ves sufficient space for he ornamental thread, so that as it is carried underneath the foot by the teed ot' the fabric be distorted or displaced by the presser foot. In Fig. 8, I have shown diagrammatically, a seam which may be made by my improved device. In this figure, two needle punctures c, 0, are made by one descent of the needles 5 and 6. The ornamental thread is indicated by a, and the loop formed by the long hook 19 is indicated by I), while the loop formed by the hook 18 is indicated by d. It will be seen that both strands of the loop b are carried back of one needle puncture,

in one line of stitching and the loop is so laid that the next needle puncture in said line of stitching will enter said loop-and' secure the same to the fabric.
