DEVICE FOR EMBELLISHING EMBROIDERY.

Application filed February 2'7, 1913.

To all whom it may concern Be it known that I, lsIDoR SOHEFF- nvncnr, a subject of the Austrian Emperor, and resident of Lustenau a small place in the Vorarlberg, Austria-fiungary, have invented a Device for Embellishing Embroidery, of which the following is a specification.

This invention has reference to certain new and useful improvements in embroidering machines and concerns more particularly a device applicable thereto for embellishing embroidery.

I am aware that it has been previously proposed to construct devices for use with embroidering machines in which the ornamental or embellishing thread is guided by means of specially arranged thread-guides.

The present invention is distinguished from devices of the kind in that the fancythread apparatus cooperates with a festoonstitch device in such a manner that the fancythread is inserted in a loop of the festoon, the object being to prevent, as it so often happens in other apparatus, the damaging of the pattern when the latter is out.

In order that this invention may be more clearly understood reference is made to the accompanying drawing, in which Figure l is a partial front view of my device; Fig. 2 is a side elevation of Fig. 1;

Figs. 3, 4 and illustrate different positions of the thread and the thread guides during the working process; Fig. 6 is a detailed view of one of the steps in the production of the festoon; Fig.- 7 illustrates a further step; and Fig. 8 represents the last step in the production of the festoon.

The fancy thread bobbins or spools i which furnish the tuft for the ornament are mounted on pins 3, and the latter are in turn carried by a plate 1 supported by uprights 5.

6 is a brake cylinder, 7 athread guide shaft, and 8 a thread guide rod, the supaortin shaft and su 3 )orted rod bein connected by lever 9.

rlttached to the uprights are brackets 10 adapted to serve as a bearing for slidable and U-shaped guide pieces 11 having suitable slots, not shown projecting through which are bolts 13. The latter are provided with a head 15 and between the said head and the upper-most member of the guide pieces 11 are coiled springs l l in such Specification of Letters Patent.

a manner that they tend to press the guide pieces 11 firmly against the brackets 10. A bar 16 is attached to the face of the guide pieces 11 and has projections 17 fashioned thereon, which serve as guides for the fancy threads 23. These projections are bent up at the lower ends into members 18 each having a guide hook 19 and an eye 20. The festoon hooks 21 are of known construction and are connected with each other by means of a second bar *2. The fancy threads 23 are guided in the known manner over the braking roller 6 and the guide shaft 8 whence they pass through the guide hooks l9 and ey lets to the cloth 24's.

Referring to F 6 and 7 25 designates the embroidery thread which by means of the festoon device is arranged in a number of loops.

The operation of the device described and the production of the new festoon together with the fancy threat-s is as follows: In connection herewith only one fancy thread guide, festoon hook, etc. is taken into consideration, and the needle N is drawn out of the stitch hole a. (Fig. 7), so that the embroidering thread runs from the stitch hole a in the embroidery ground to the needle, while the fancy thread 23 runs from the em broidery ground to the fancy thread eye 20. The festoon hook now moves out of the position shown in Fig. 1 upward into the positionshown in Fig. 3, the fancy thread 23 being taken hold of between the e1nbroidery ground and the eye 20 and the embroidering thread 25 between the embroidery ground and the needle N by means of the fork of festoon hook 21. Hereupon the embroidery ground is raised and at the same time moved to the left, so that the point in the material where the next following stitch hole 7) (Fig. 7) is to be made, comes in front of the needle, while at the same time the fancy thread guide 17 is moved from left to right, and assumes the position shown in Fig. 4 directly in front of the needle, having thus passed the thread 23 under the thread 25. The stitch hole Z) Fig. 7) is now made and the embroidering thread 25 lies over the fancy thread 23 (Fig. l). After the needle has been pulled out of the stitch hole 7; the fancy thread guide 21 moves from right to left into the. position shown in Figs. 5 and 8. The fancy thread 23 is drawn tightly between the needle N and the embroidery ground, and in consequence of greater tension of the fancy thread the open loop 25 of embroidering thread is drawn out. Hereupon the embroidery ground is lowered and at the same time moved somewhat from right to left, so that the point in the material where the stitch hole 0 (Fig. 7 is to be made, lies in front of the needle and in consequence of the more powerful. tension of the shuttle thread the embroider-mg thread loop 25" is drawn out on the back of the embroidery ground. The insertion of the needle at 0 (Fig. T) is now effected. This stitch hole is efiected on the left of the fancy thread carrier 17, to the right hand of the stitch holes a Z), and to the left of the embroidering thread that comes from the stitch hole I) and embraces the fancy thread. During the insertion of the needle N in the stitch hole 0 the festoon hook 21 moves downward into the position shown in Figs. 1 and 6, the festoon thread, as well as the embroidering thread coming out of its fork, having the necessary tension thereon, which tension has effect back to the stitch hole a.

The described operations are performed by all automatic embroidering machines which are under the influence of the jacquard card, such machines also allowing of the necessary alterations in the position of the frame, for the purpose of effecting the proper needle insertions at a, b, 0, etc.

What I claim and desire to secure by Letters Patent is:-

1. In an embroidering machine, a bobbin supporting plate, a brake cylinder supported below the bobbin supporting plate, a thread guide rod associated with the brake cylinder, a bar supported below the bobbin supporting plate, thread guides comprising depending hook members integral with the bar, a guide lug on each hook member, a movable bar operating under the first mentioned bar, festoon hooks carried by the second mentioned bar, said festoon hooks adapted to cooperate with the thread guides for looping the thread and carrying the same before a needle, said thread adapted to be fed over the brake cylinder.

In an embroidering machine, a bobbin sup} )orting plate, a brake cylinder under the bobbin supporting plate, thread guide rod pivotally supported adjacent the brake cylinder, thread guides under the thread guide rod, a movable arm carrying festoon hooks, said festoon hooks and thread guides adapted to cooperate for looping thread, and resilient means for permitting movement of the thread guides in one direction.

3. In an embroidering machine, a frame. comprising uprights, a bobbin supporting plate on the uprights, a brake cylinder under the plate, a. thread guide rod supported adjacent the brake cylinder, a bracket supported by one of the uprights, a pin eX- tending above the bracket, a bar supported under the thread guide rod, said bar having U-shaped members adapted to embrace the pin, resilient means engaging the U-shaped members for restricting vertical movement of the bar, thread guides forming a part of the bar, festoon hooks cooperating with the thread guides for looping threads, and means for sewing the looped portions together.

In testimony whereof I have hereunto set my hand in the presence of two subscribing witnesses.
