EMBROlDERlNG-MACHINE.

SPECIFICATION forming part of Letters Patent No. 361,747, dated April 26, 1887.

Application filed May 19, 1886.

To all whom, it may concern:

Be 1t known that I, EMIL CoRNnLY, a resident of Paris, in the Republic of France, have. lnvented anew and useful Improvement in Eur' broideling-lldachines,` which-is fully set forth in the following specification.

In Letters Patent of the United States No. 311,644, of February 3, 1885, I have described and claimed a new method of fixing cords or braids to textile fabrics by winding a thread around said cord and around the stitch of a sewing or embroidering machine. The method explained in said Letters Patent can equally be applied when stringed beads are to be iixed to textile fabrics; but inasmuch as a string of beads passes with great difficulty through the machine on account of its asperities, it requires special mechanical devices for obtaining a good result. They will be understood by reference to the following description and the accompanying drawings.

Figure'I represents an elevation of the head of an embroideringmachine. Figs. II, III, and IV represent detached views, hereinafter to be referred to.

As the general construction and operation of the machines to which thepresent invention is or may be applied are well understood, and are, moreover, fully described in Letters Patent heretofore granted to me-for instance, in Letters Patent No. 228,445, dated June 8, 1880, and 262,742, dated August 15, 1882-it will only be necessary to describe herein the particularparts or improvements which constitute the present invention.

I employ a string of beads 011 which each bead is fixed by means of a second thread in such manner that there will remain a small space between each two following beads. As such strings of beads are already manufactured for weaving purposes, they can be obtained easily and cheaply.

The same as in Letters Patent N o. 311,644,

` A represents the cloth; B, the needle-hook; C,

the nipple; a, the cording-guide; D, the nipple-tube; E, the needle-bar; Ghthe rotating thread-carrier; H, the string of beads to be xed to the material.

I employ a hollow or tubular needle-bar, E, which is provided at its top with a funnel, b, into which the string of beads can glide without hinderance, and through which it can descend through the entire length downward and along the needle B, and thence through the cording-guide c, and downward to lthe cloth, to which it is fixed bythe thread, which is wound by the thread-carrier G around the string and around the loop-stitch of the machine, as explained in Letters Patent 311,644.

To insure perfect work, it will be necessary, when working on very thin material, to employ an automatic feed device to supply a certain length of stringed beads to the material. This feeding device may be composed of two small cylinders, d h, of indiarubber, or of 6 5 other material,which turn within a small frame of the nipple-tube D. They are connected together by means of two pinions, m o, Fig. IV, and the cylinder d is provided with a rack, s, which, when the nipple-tube D rises, strikes against a small spring-pawl, a, which is secured to the fixed tube g, within which the nipple-tube operates. The string of beads is wound around the cylinder h, and, passing between the two cylinders hand d, descends to the cloth through the guide a. As the nipple-tube rises at each stitch the cylinders d and h turn and feed a certain length of string to the work. The thread, as it passes from the spool q, through the guide r, and through the thread-carrier Gr, is wound in such a manner around the string of beads that it will always place itself within the space which exists between two beads, and it will therefore not be visible. The hollow needle-bar E is secured to the tube T by means of a set-screw, o, and the tube T receives its vertical reciprocating motion for operating the needle-bar E by the well-known means employed on sewing and embroidering machines.

The ap paratus,consisting of the parts V, X, Y, and Z, h', 7c, o, p, and n, is the same as the one for which application for Letters Patent has been made by me, (No. 156,527, filed February 20, 1885,) and which serves to tighten each loop of the chain-stitch when the needle commences its downward movement. This apparatus is equally effective for making beadwork.

It is evident that bead-feeding appliances of 10o various constructions may be made instead of the feed-rollers above described, and I thereA est, `and. Fig. iii in its highest, position.

A similar bead-feeding device can also be applied at the top of the needle-bar, or at its funnel-shaped mouth, to supply the desired length of the bead-string to the work, which in many cases is necessary, as the ordinary tension on spools of sewing-machines does not work effectively on the spool on which the bead-string is wound.

l. In a sewing or enibroidering machine of the character described, the combinatiomwith the stitch-forming mechanism, of the hollow needle-bar provided with a funnelshaped month, substantially as and for the purpose set forth.

2. The combinaliomwith the stitch-forming devices and the rotating carrier for wrapping a second thread around the sewing-thread, of the hollow needle-bar having a funnel at its upper end, and the 4guide a, for directing a cord or string of beads to the fabric, substantially as described.

3. The combination,with the stitch-forming devices and rotary carrier for Wi nding a second lthread around, the sewing-thread and around a cord or string of beads, of automatic feeding mechanism for supplying a certain length of cord or string to the work, substantially as described.

4. `The combinatiomwith the reeiprocatory needle-bar, of the feed-rollers carried thereby or connected therewith, and means, as specied, for rotating said rollers step by step at each reciprocation of the needle-bar, substantially as described.

5. The combination of the hollow reciproca: tory needle-bar, the feed -rollers geared together'and carried by said needle-bar, a rack or ratchet on one of said rollers, and a pawl carried by a part of the machine, stationary with respect to said needle-bar and arranged to act upon said rack or ratchet at each reciprocation of said bar, thereby rotating said feedrollers, substantially as described.

In testimony whereof I have signed lthis specification in the presence of two subscribing witnesses.

- EMIL CORNELY.
