SPECIFICATION forming part of Letters Patent No 340,422, dated April 20,1886.

Application filed June 16, 1885. Serial X0. 168,848. (No model.) Patented in France May 23, 1882. No. 149,127.

To all whom it may concern.-

Be it known that I, EMIL CORNELY, of WVashington, in the District of Columbia, a resident of the city of Paris, in the Republic of France. have invented a new and useful Method for Fixing Cords or Braids to Textile Fabrics by Means of Sewing or Embroidering Machines,(for which I have received a certificate of addition, dated February 8, 1884, to French Patent N 0. 149,127, dated May 23, 1 882,) which is fully set forth in the following specification.

In Letters Patent No. 811,644 I have described a method for fixing cords or braids to textile fabrics by means of a thread which is wound around the cord and taken into the seam of a sewing or embroidering machine.

The present method is different from the one above mentioned, and it consists in fixing the braid or cord to the seam of a hook-needle by winding around the needle and around the cord the thread which is employed for producing the seam itself.

Figure 1 represents an enlarged view of the seam, together with the operative elements for producing it. Fig. 1 represents a plan view of the top orhighest portion of plate M, hereinafter referred to. Fig. 2 represents an elevation of the entire machine. Fig. 3 rep resents a section through the driving-gear of the revolving thread-carrier.

In the original single-thread embroideringmachine, which produces the chain-stitch by means of a needle-hook, an oscillating looper is employed under the cloth-plate for winding the thread around the needle in such a manner that the needle-hook upon rising will draw a loop above the cloth to produce the chainstitch in the well-known manner. In the said machine the needle, as well as the looper or thread-carrier, is geared to the crank-handle of the machine, so that they can be governed in accordance with the universal feed.

Instead of employing an oscillating looper or thread-carrier, a continuouslyrevolving thread-carrier can be employed, which in its rotationsaround the needle-hook will produce the same result as that obtained by an-oscillating looper; but this can be obtained only on the condition that during its revolutions around the needle the thread-carrier can be governed by the crank-handle of the machine. In Letters Patent No. 262,742, of August 15,

1882, I have described and claimed such a revolving thread-carrier.

In Fig. 1,0 represents the cloth-plate of the machine; 0, the cloth; h, the needle-hook; b, a th read-carrier,which turns around the needle in a continuous revolving motion; (7, a cordingguide, which is behind the needle-hook h, through which a cord or braid, P, is drawn, which, passing from a spool from below, is laid between the cloth-plate O and the cloth 0. The revolvingthread-carrier 1) turns around the cord P and around the needle h, and winds its thread simultaneously around both of them. The needle h, upon rising above the cloth, draws a loop upward in the same manner as is the case in the single-thread embroidering-machine,andproduces the ordinary chainstitch, within which the cord P is secured, in the manner represented at Fig. 1. The thread f of the threadcarrier I), being wound around the cord P and around the needle h at the same-time, naturally fixes the cord securely to the cloth.

The thread-carrier b may be operated by the means described in Letters Patent No. 262,742, or by those described and claimed in application, Serial No. 168,736, filed June 16, 1885, consisting of a series of pinions and cogged wheels. (Represented at Figs. 2 and 3.)

A screw-wheel, g, is secured to the main driving-shaft D, and actuates a similar horizontal screw-wheel, h, and its shaft m, the pinions n 10, the shaft q, the pinions A G Eat, shaft N, pinions R T, K L B, and the threadcarrier b and its thread-spool, which are secured to the hub of wheel B. As explained in the application referred to, the threadcarrier b can be governed by the crank-handle S by means of the pinions u r H I, shaft Q, and pinions a.

The cordingguide d consists in a circular plate provided with a truncated cone, M, in which an oval space, d, is made for the passage of the needle-hook h, and behind it for the cord P. The plate M is secured to the upper rim of the wheel w, which is in gear with a similar wheel, 2, to which apinion,o, is secured, which is in gear with the pinion s of shaft t, and which can be governed by the crankhandle S by means of the pinions u r.

The wheel Bis mounted upon the tube 2, which is secured in the frame 3. There is a small pulley, at, which turns on the tube 2, and is connected by a belt or chain, 7, to a pulley, 6, of the crank-handle. The cordingspool 5 is supported by a bracket, 8, which is also secured to the pulley 4.

Thus all the operative elements of the machine,besides performing their motions which are necessary for the work, can be governed by the crank-handle S, as follows: First, the needle and the universal feed are governed by means of the gearings r u, m U V, and Y Z; sec- 0nd,the revolving thread-carrier I) by the gearings *r u H I, shaft Q, gearings a v, R T, and K L B; third, the cording-guide (Z through the gearingsru, s o, and z w,- fourth, the cording-spool 5 through pulleys 6 and 4.

Having thus fully described the nature of my invention, I claim 1. The method of fastening a cord, braid, or similar article toafabric by a hook-needle, by winding a thread around the cord and the in e He, and forming from said thread a series of stitches in the fabric, so that the thread envelops the cord and secures it to the fabric, substantially as described.

2. The combination, with the hook-needle and cloth-plate, of the cord-guide below the cloth-plate, and the thread-carrier, also below the cloth-plate, for wrapping the thread around the cord,as well as to introduce itin the needle hook, substantially as described.

8. The combination, with the hook-needle, the cloth-plate, and the mechanism for controlling the direction of the feed, of the continuously-revolving threadcarrierbelow the cloth-plate, connected with and governed by said feed controlling mecha-nism,substantialIy as described.

4. The combination, with the needre-hook and the cloth-plate, of the continuously-revolving thread-carrier and the cord-guide, both below the cloth-plates,and the mechanism for operating said needle, thread-carrier, and cord guide, substantially as described.

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