To all whom it may concern:

Be it known that I, ISRAEL M. RosE,-of

B-rookhaven, in the county of Snfl'olk and State of New York, have invented certain Imfioveinents' in Embroidery Devices, of which braid not passing through the fabric, but

being" secured thereon bystitching it to "pend the surface thereof. This thread enchaining device is mainly composed of a vibrating needle, operating in combination with a presser-foot andjfeeding mechanism, said needle constituting an embroidery-thread carrier,

which has a vibratory motionin line of the length of .the braid or enchained stitch, and,

as an attachment to a sewing-machine, may, for convenience sake, be operated by the needle-bar thereof,lbut the action of which is independent of that of the sewing-needle used- 'to stitch or sew the enchained embroiderys titch on the surface of the fabric. The invention also consists in various peculiarities of construction and combinations of parts' as regards said thread-enchaining device and its proposed attachment to asewing-machine.

Figures 1 and 2 represent top views of -my improved embroidery device as an attachment to a sewing-machine, and Fig. 3 a face View of the same. I p A is the presser-foot of a sewing-machine,

of suitable construction, and B the shankor' holder of said foot, which, may be adjustable,

if desired, in the customary manner.

The sewing-machine to which my improved embroidery device is applied as an attachment may be of any suitable description,

either arranged to work one thread only, or with a shuttle; and I do not-confine myself in; the use of my invention tothe use of any cu1ar kind of seWing machine. o the resser-foot shank at a is pivoted a 01* bar, 0, which has two shoulders, b d;

A projection on thejncedle-bar (Snot shown) is in line with thesetshoulders, an strikesthe shoulder b during the ascent of the needlebar the arrow 1, Fig. '3, while during the descent of said needle-bar its ,said projection strikes the shoulder d,'thereby turningthe plate 0 on its pivot in the direction of the arrow 2, Fig. 3. This use of the needle-barof the sewingmachinefor operating the thread-enchaining devicedoes away with any special device for the purpose. 0n the back, or, if desired, on the face, of the plate 0 is hunga swivelingarbor, D, in such manner-that it can swivel or swing independently on its own 'axis, its indeentoseil-latiens-being controlledby a slotted guide, 8, which projects backwardly from the shank of the presser-foot,- and into which slot a crank, f, of the arbor D enters. Thelower end of said arbor carries a projecting arm, g, to which a latch-needle, E, is rigidly secured by means of a set-screw. or otherwise.

This lat'ch -needle, during the oscillations of the plates 0, is carried intothe twoextreine positions'in Figs. 1 and 2-that is to say, during the downward motion of the needle-bar, when the plateC is swung in direction of the arrow 2, the latch-needle is carried above and across the presser foot into the position's'hown in Fig. 1, and during the subsequent upward motion of the needle-bar, when the plate Cis swung in direction of the arrow 1, the latchneedle is carried clear of and beyond the presser-foot into the position shown in Figs. 2 and.3. Fastened to the end of the presscrfoot is awire guide, F, which, is formed at h into a loop through which the thread used to form the embroidery braid or enchained thread is drawn, after having passed throughor over 1 suitable tensiondevices.

When theneedle-bar descends and causes the latch-needle E to move toward the loop h,

saidvlatch-needle-catches under and takes hold of the embroidery-thread,- which is shown at i in Fig. 1; and during the subsequent ascent of the needle-bar the latch-needle, swinging away from the loop h, carries the embroiderythread with it across and over the presserfoot;v and at the end of ,its' movement in this direction the latch-needle will be swung in di- Y swinging'the plate 0 in the direction of rection of the arrow 3, Fig. 2, by the crank f moving in the loop h or stationary slot e,'into which it is laterally deflected at the end of the upward vibration in direction of the arrow 1 ot the plate (J. This lateral movement of the latch-needle E causes the same to pass or stand behind the sewing-needle, so as to be out of the way thereof, and in this position that portion of the embroidery-thread which lies across the presser-foot is sewed down during the descent of and by theisewing-needle and its thread. The subsequent vibration of the plate 0 in direction of the arrow 2 causes its latch-needle to pass through the loop last formed of the enchained embroidery-thread, and toretain such loop on the shank of said needle, and to open the latch of the latter, so that said needle can again take hold of a new part of the embroidery-thread and draw it back over the presser-foot, in the manner hereinbefore described. Upon its arrival, however, in the position shown by Fig. 2, the latch becomes closed by the loop which was previously placed on the needle-shank slipping over and otf the latch-needle, leaving, however, the last portion of thread carried on such needle to form the succeeding loop, and so on indefinitely.

In this manner an embroidery-thread is enchained within itself like tambonr-work, or, in other words, like the chain-stitch made by an ordinary v single thread sewing machine, bntwithout passing such thread into or through the cloth, merely laying it (after it has been enchained) in the form of a braid on' the sur face of the cloth, where it is sewed down by the ordinary action of the sewing-machine or other needle. I v

In place of the latch-needle herein described,

and of the guide or loop h, I may use an ordinary eye-pointed needle, and in conjunction therewith a spring-holder for retaining the embroidery-thread, said spring-holder being so arranged that the vibrating needle will pass toward it on one side, and from it on the other, to form the succession embroidery-thread.

I claim 1. An embroidery-thread-ench ainin g device, constructed substantially as described, where by said thread, without passing through the of loops of the -fabric',"'is enchained within itself, and laid in the form of a braid upon the surface of the v fabric, for attachment thereto by sewin 2. The enibroiderythread carrier consisting of the vibrating plate 0, latch-needle E, and connecting mechanism, substantially as de scribed, arranged as specified, for laying an embroidery-thread upon the surface of the fabric, as setforth.

3. The combination of the latch-needle E, the rock-shaft D, to which it is attached, and the vibrating plate 0, on which the said rockshaft has an independent axial motion, substantially as herein "described.

4. The combination of the latch-needle E and the guide h 011 the presser-foot, substantially as and for the purpose herein specified.

5. The embroidery-thread carrier of an embroidery attachment to a sewing-machine, arranged and organized substantially as herein described, whereby it is enabled to perform a longitudinal and a lateral motion, as and for the purpose herein specified,

6. The combination of a sewing-mach ne needle with a vibrating embroidery-thread carrier, E, as set forth.
