EMBROIDERING AND EDGING MACHINE.

SPECIFICATION forming part of Letters Patent No; 626,367, dated June 6, 1899. Application filed February 19, 1898. Serial Nol 670,959. (No model.)

To all whom it may concern:

Be it known that we, EMIL CORNELY and ROBERT CORNELY, citizens of the United States, residing at Paris, France, have invented Improvements in Embroidering and Edging Machines, of which the following is a broidering-seams of variable width.

In order to facilitate the comprehension of this invent-ion, it is shown in the accompanying drawings in this application upon the machine described in Letters Patent No. 462,858, of November 10, 1891, in which the needle effectuates an oscillating motion, and thus, according to the length of the stitches, pro duces overseamiug, zigzag, or edging seams.

In said drawings, Figure 1 is a side elevation of a machine embodying our invention. Fig. 1-is a plan of the thread-guide and tension devices seen at the top of Fig. I. Fig. 2 is a vertical section of the crank-handle and parts connected therewith. Fig. 3 is an elevation of the crank-handle and lever. is a view of the same, showing the parts in a different position. Figs. 5 and 6 are views of modified forms of crank-handle and lever. Fig. 7 is a fragmentary detail, and Fig. 8 is a broken elevation showing means for operating the stop mechanism by foot.

The oscillating motion of the needle-bar is obtained in the following way: The main shaft R of the machine, Fig. 1, is provided with a small cog-wheel which drives a cog-whee1 Q of double its size. This cog-wheel Q is provided with a cam 72,, which operates lever P, thelatter (lever P) playing upon its fulcrum q. The horizontal arm of lever P operates slide F, which by means of its fork it drives cone I. This latter (coneI) works against pin 2 of Fig. i

sliding part C, When, therefore, cone I descends, then it pushes sliding part 0 to the pressure of cone I, and the sliding part 0 is then moved to the right by the action of spring 3.

Needle-bar M is suspended at its upper end by means of a ball-joint 0, while the under end of said needle-bar projects through sliding part 0, which thus transmits its oscillating motion to the needle-bar. An eccentric disk S plays freely upon its pivot f, and the under edge 4 of said disk S forms an eccentric curve to its fulcrumf. In its oscillating motion 1ever P strikes against eccentric disk S, and according to the position of said eccentric disk S the motion of lever P will be increased or decreased, and therefore according to the eccentric disk S being pushed to the right or to the left the motion of the slide F will be increased or decreased, and consequently the oscillating motion of needle-bar M will vary accordingly, thus varying the width of the seam. It is therefore necessary, inorder to vary the Width of the seam according to the work required, that the operator should be able to shift the eccentric disk S while the machine is in operation. For this purpose We utilize the stop-motion described in Letters Patent 'No. 182,804, of October 3, 1876, but changing :it in such a way that this stop-motion while operating the eccentric disk S still governs the stop-motion of the machine, as well as the direction of the feed. This new arrangement is represented in Fig. 1 and on a large scale in Figs. 2, 3, and 4, wherein N is the handle of the stop-motion,which is secured upon tube (1, provided with a circular groove g, which tube slides freely up and down upon rod 13. A lever G swings upon pivot 5. One of its ends penetrates into groove 9, while its other end works against the end of tube E. When now handle N is pushed downward,then lever G pushes tube E upward. This tube E acts against the end 3 of lever D and pushes itupward, whereby the other end 2 of lever D, Fig. 1, descends and draws the stop-motion rod A downward, thus throwing the machine into gear.

The mechanism which operates the eccentricdisk S is composed of lever T, which works upon its pi.v0t.5, which is secured upon the handle Nbfthe stop-motion. Theshort'arm 6 of this lever works against a sliding collar provided with a groove m. While working, the operator holds the handle N by means of the thumb, forefinger, and middle finger in order to throw the machine into gear and to govern the direction of the feed. At the same time the two other fingers can press against the end of lever T and push it into thegroove of handle N, as represented in Fig. .4. In this'case the collar m is pushed upward, whereby the end 7 of lever V descends, and with the latter rod W, Fig. 1, and the end 8 of lever X, while the end 9 of said leverX' is pushed upward. This lever X worksagainst pin 10 of rod Y, which atits upper end is provided with a pin 11. This pin 11 operates lever Z, which latter by means of" rod U transmits its motion to lever 13, which operates eccentric disk S, and thus shifts this disk as may be required in order to regulate the oscillation of lever P according: to the width of scam desired. lVhen the pressure upon lever '1 ceases, then spring 14c pushes lever 13 to the right, and thus the whole system of levers U, Z, Y, W, V, and T returns back to thep'osition represented in Figs; 1 and 2.

When edging-scallops are to be produced the scallops of which have to be broad in the 'nriddle and narrowtoward the angles of the arcs, then the motion of the eccentric disk S turning motion of the crank-handle N is transmitted totooth-wheel 17 by means of wheels 18; 19, 20, 21, and 22, and thus the eccentric in F-igs. 5 and 6. In this case the handle itself is-composed of twolevers 35 and 36, which act'at the same timeas handle and as levers.

Thesetwo levers are secured upon tube37,

uponthe cloth by the action of spring 26 and 1 which isitself placed upon tube (1,, as abovedscribed in reference to Figs. 2, 3, and 4. When the twolevers35 and 36 are pressed together; then the pressure of their upper ends 6 producesexactly-th'e' same motions as above described inreference to Figs. 2, 3, and lr;

For'the formation of the seam the small presser-nipple 25, through which the needle passes; has-to press the cloth aslong as the needleis in the cloth. Thisnipple 25 is pressed is lifted upward by the motion of the needlebar M, which; is for this purpose provided with a projection which takes hold of the nipple 25 at the right moment.

The sewing or embroidering silk or thread ,comes from spool 27, from. whence it goes through guides 28 and 29, then around turning disks 30, through guides 31 and 32, guide 134, and at last through the eye of the needle.

Fig. 8 represents the same machinein which the stop-motion of the machine is operated by ;the foot of the operator by means of rod 40, which acts upon lever D, the stop-motion rod A, and thus throws the machine in gear, as above described. The eccentric disk S is then operated by the crank-handle N by means of ,levers V,W, X, Y, Z, U, and 13, as above described.

In sewing and embroidering machines, the combination of universal feed mechaniism, a crank armand handle foroperatin g the same, an oscillating needle and means effect- ;ing the oscillations thereof,with a regulating Zdevice for'said means normally held in a pre-' determined position, and a lever pivoted on,
