i Application filed Juanuaryvl/l, 1911. Serial No. 602,576.

To all whom t may concern v Be it known that I, ISRAEL A. ANToroL, a citizen of the United States, and a resident-of the borough of Brooklyn, in the county of Kings and State of New York, have invented certain new and useful Improvements in Embroidering-Machines, of which the following is a specification.

My invention relates to embroidering machines, and has for its principal object to provide in machines of this character, mechanism for sewing with invisible stitches, a cord, piping or braid onto the material to be embroidered, and at the same time, twisting a thread or cord about said first mentioned cord, piping or braid, while the latter is being sewed onto the material.

A further object of this invention is` to provide means for varying the spacing of the convolutions of the thread or cord, as it is being wound about the other cord.

A still further object of this invention is to provide means whereby the reel carrying the thread or cord 'may be rewound without taking it olf from the machine.

Other objects will appear from the detailed description, and will be more detinitely pointed ,out in the accompanying claims. r

In the drawing yillustrating this invention: Figure 1 is an elevation, partly in section, of an embroidering machine, with my invention applied theretow-Fiig is an ele'- vationy partly cut away, illustrating vthe means I provide for rewinding the reel carrying the thread or cord. Fig. 3 is a plan illustrating diagrammatically the speedchanging gearing for varying the spacing of the convolutions of the thread or cord.A Fig. 4 is an elevation of the mechanism illustrated in Fig. 3. Figs. 5, 6, 7 and 8 illustrate the reel and the method of its mounting. Fig. 9 is a sectional detail view, on ,an enlarged scale, taken along line a in Fig. 1.

1 indicates the needle shaft which is driven by pulley 2 and operating needle-bar 3 in the usual manner. Spool 4 carries thread 5, which' runs through needler 6011 the needle-bar, to -form the ordinary lockstitch. Mounted on the same bracket with spool 4 is a spool 7 carrying a cord, piping yor braid 8, which is threaded throu h the opening through which the nee le-bar passes, and'is lthen guided by guiding member 9, so as to present the under side of the cord to the needle, as illustrated in Fig. 9.

The guiding member 9 has a lateral opening 10, through which the cord enters, andan additional opening 11, through which the cord passes out'again, forming a loop, the apex of which projects in opening 1,2, through which the needle passes. It-will be seen .that as the material 13 and the cord are fed along, the stitching which engages only the under side of the cord, will be concealed. I illustrate the lower thread 14 of the lock-stitch, but the mechanism below the table is omitted for the sake of clearness. The stitching is omitted in Fig. 1, and the windings of the thread about the cord are' omitted in Fig. 9, for the same reason. It will be understood that any mechanism for producing a lock-stitch may be used in connection with my improved machine.

Projecting from the arm of the machine, is a bracket 15, having a depending tubular bearing or sleeve 16, on which is mounted a sleeve 17 having a gear-wheel 18 at one end, and a threaded portion 19 at its other end. Reel 20 is mounted on the sleeve and is held in positionv by nut 21,V which engages the threaded portionv 19 of sleeve 17. This reel is provided at its upper end with a gear-wheel 22, the' purpose of which will be' hereinafter described. Reel 20 carries Vthe thread or cord 23 which is to be wound around cord, braid or piping 8. This thread or cord is guided in a bracket 24, which is attached'to the nut 21, and an eX- tension 25 fastened to the bracket. The reel is frictionally held to sleeve 17 by a spring 26 which is pressed against it by a screwv 27,` threaded in the nut 21. When the gear 18 is rotated, the reelis frictionally carried along with it, and the thread 23 is wound around the cord 8. Gear 18 is driven from needle shaft 1 as follows: Fixed to the needle shaft is gear 28 which drives the pulley shaft 29 through gear 30. The motion of this last shaft is transmitted-by bevel gears 31 to shaft 32 which has mounted thereon a gear y33, having several rows of teeth of varying diameters, each of which rows may be brought into driving engagement with an idler gear 34, mounted' on a pin adjustableinsot 35. This idler transmits its motion to ear 18 through a' second idler 36.- All of tlis gearing which transmits the motion-.from the gear 28 to gear 18 is mounted ina bracket 37 and an extension 38.- projecting laterally from this bracket. When it is desired to change the spacing of Patented July 9, 1912.

the convolutionsef the thread, idler 34 is 4 loosened and moved out of Gear 33 is then 40. Mounted in'this bracket is a which meshes with gear .22 on ,the ree manually by crank guide having an opening and slid along until latter can then be turned 42, shaft 43 and gear44 and 45'. With my improved machine, scribed, a cord, piping or braid can be embroidered on material, and 4another cord or lthread can be wound around it with acen-l ,siderable space between the convolutions,

'and still no ,stitching will be seen onV account of the manner in which thetcord is sewed on tothe material. The thread can be of different color from the cordon which itis wound, and thus a highly ornamental effect is obtained. I preferably `employ a lock stitch for sewing the cord on to the mate rial in order -to prevent the customary raveling accompanying the 'use of the chain stitch. The lock stitch isalso preferable for the reason that it takes better hold' of the material than the ordinary forms of chain stitch. IIowever, it is obvious that any form of stitch may be used without departing from the spirit of this invention.

It will be noted that the reel containing the thread can be rewound without its be- 'in removed from its position -on the machine. -This saves a great deal of time and labor.V The concentric mounting of this reel renders thev whole structure compact,

and makes it possible to usela larger reel without taking up too much space. Moreover, danger of hitting the operator,

taining eccentrically moiinted.wheels,. is avoided. y

Where the term cord is used in the claims, it is contemplated' to designate generally, cord, piping or braid.
