EIVIBROIDERING-MACHINE.

SPECIFICATION forming part of Letters Patent No. 228,445, dated June 8, 1880. Application ilcd December 27, 1879. Patented in France March 28, 1879, and in England July 16, 1879.

To all whom t may concern:

Be it known that I, EMIL OORNELY, of Vashington city, in vthe District of' Oolnm bia, a resident ofthe city of Paris,iu the Republic of France, have invented certain new and useful Improvements in Embroidering-Machines; and I do hereby declare that the following is a full, clear, and exact description of the construction and operation of the same, reference being had to the annexed drawings, in which- Figure l represents an elevation of said machine, the arm and head to which my present invention is applied being shown in full lines, while all below the cloth-plate is shown in dotted lines, for reference only, as not having any relation to the subject-matter of this invention. Fig. 2 represents an end view ot' said machine. Fig. 3 represents adetached view of that part ofthe machine to which my improvements are applied. Figs. 4, 5, and Gare detached views, hereinafter to be referred to.

y invention relates to the embroideringmachine for which Letters Patent were granted to me as assignee of Antoine Bonnaz on the 10th day ot' November, 1868, No. 83,910, and has for its object the production of an einbroideringstitch which is obtained by winding a second thread at each stitch around the needle or the needle-thread ot' said embroidering-machine.

The construction and operation of said embroidering machine being fully known, the drawings and descriptions are limited to the subject-matter of the present invention.

The letters of reference in the drawings for the like parts are the same as those in the specification of the patent of November 10, 1868, No. 83,910.

d represents the nipple of the machine, with in which the needle-hook plays to produce the ordinary chain-stitch embroideringseam.

The nipple d is secured to the nipple-tube H, which plays within the hub A of the casting of the machine, and which is elongated, so as to make room for the gearings, the threadcarrier, the spool and tension ot' the second thread.

A toothed wheel, B, is fitted upon the hub A, and can turn thereon freely. It is held in position by means of a ring, a, which is screwed to the hub A. l

each stitch around the needle or the needlethread.

The thread-carrier b is secured to the bar O by means of the strap j', and the bar O is screwed to the hub of the wheel B. Within the hub oi' the barO is also tted the cylindrip cal tension rod g, which can be turned by means of its headJL, as will be explained hereinafter.

The spool G ofthe second thread is secured to the arm E, as represented in a horizontal view in Fig. 4. Owing to the very rapid revolution of the entire mechanism around the needle, it is preferred to4 employ a iixed spool which cannot turn, and which, together with its tension, will take up a small space only, so as to be able to turn within the curved feedbar O2, Fig. 2. A conical spool, G, is secured to the arm E by means of a bolt, m, and screwnut 7c. The thread is drawn from said fixed spool in the direction of the conical line, and passes through the mouth l ofthe tension-rod g, which is in the line of the axis of spool G. The thread then passes through the hole 2, and thenceintothe eye of' the revolvingthreadcarrier b. Upon turning the tension-rod g by means of the head h the thread is wound more or less around the cylindrical surface of rod g, and thus its tension can be regulated at pleasure.

In employing silk or other twisted thread it happens frequently that the thread does not pass regularlyfrom the spool G through the tension g. To obviate this difficulty I have applied to the spool G afriction-guide, n, (represented in detached views in Figs. 5 and 6,) which is secured between the spool G and the arm E by the pressure of the screw-bolt m on its forked end 4, while its front end has a circular openin g which iits coucentrically against the head 3 of the screw-holten, leaving asmall annular space between the two for the passage of the thread, which then passes through the eye of the tl'ireadguide, and thence into the mouth 1 of the tension-rod g. Thus, while the spool, tension, and thread-carrier b turn o-r ro- IOO tate around the needle, their relative positions to one another do not change, and the second thread is wound regularly at each stitch around the needle or the needle-thread.

As I have already stated, the invention relates particularly to the Bonnaz machine, and in order to communicate the requisite motion from the main shaft D of that machine to the thread-carrier b diiiculty was experienced on account ofthe shaft W, by which the feed motion is directed, the position of which cannot be changed without modifying considerably, if not entirely, the construction of the machine. The employment of outside shafting and gearing for this purpose renders the machine too complicated for efficient use. The difficulty is overcome by means of asleeve or hollow shaft, M, Figs. l and 3, which is titted into the casting ofthe machine, or is only slipped over the shaft WV in such a manner that both shafts M and can turn or rotateindependentlyone ofthe other.

The cogged wheel N is secured to one end of the sleeve M and receives its rotary motion from the pinion Q, which is secured to the main shaft B. The pinion R, which is secured to the other end of the sleeve M, imparts a rotary motion to the pinion T land to the cogged wheel K, which both are secured to the vertical shaft p, and which transmit their motion to the wheel B and to the thread-carrier b by means of the intermediate pinion, L, while the free rotation of the shaft T is in no way obstructed by the rotation of sleeve M.

It is evident that the sleeve M and the gea-rings N and R may be made of one and the same piece, and must be considered as such in their operation.

By ungearing the wheels Q, and N the motion ofthe thread-carrier b is arrested, and the machine makes the ordinary chain embroidering-stitch. This can be done by loosening the screws which secure the wheel Q to its shaft I), and by shifting it thereon so as not to be in gear with pinion N, or by the employment of any suitable coupling device. Such devices being wellknown to those skilled inthe art, no description is deemed necessary.

I have shown on the drawings a conical fixed spool; but a common thread-spool, set upon and supported by a vertical pin, can be employed withoutsecuring it inI any way, and, notwithstanding the high speed of revolution, it will cause no irregularity in the tension.

Having thus fully described' the nature of my invention, what I claim therein as new, and desire to secure by Letters Patent, is

l. The combination, with the thread-carrier for delivering a second thread to be wound around the ordinary needle-thread of a sewing orembroidering machine and the needle-bar of said machine, of a rod or pin for sultiporting at the side of the needle-bar the spool from which the aforesaid second thread is drawn, and mech anism for revolving` together around the axis of the needle-bar said thread-carrier and spool pin or rod, substantially as described.

2. The combination of the rod or pin for supporting the spool from which the second thread is drawn, a tension device, and a thread-carrier, all connected with lthe same pinion, and means for supporting said parts and for revolving them around the axis or path of the needle of a sewing or en'lbroidering machine, substantially as described.

3. The combination, in a sewing or embroidering machine having a top feed, with the lnain shaft rotating in the goose-neck and a shaft located below the main shaft for directing the feed motion, of a sleeve or hollow shaft encircling the feed-shaft and provided with gears on opposite ends, and a thread-carrier and connections and gears for communica-tin g motion from the main shaft, through the said sleeve or hollow shaft and its gears, to the thread-carrier, substantiaily as described.

4. The combination, with the pin or rod for supporting a spool in a fixed position, of the bent plate, having a circular opening at one end and at the other a slot which fits over said pin or rod, and a device for securing said plate in position, substantially as described.
