To all whom it may concern."

Be it known that I, Monnrs SoHonNrELD, a. citizen of the United States, and resident of-Rorschach, Switzerland, have invented a new and useful Cord-Laying Device for Embroidery-Machines, of which the following is a full, clear, and exact specification.

The cord-laying-in device s most in use are those wherein a bundle ofcords istensioned from one end of the embroidery machine to For the laying-in operation, a cord is-taken from the bundle and engaged into aspecial holder in order thatvthe said cord can be brought near to the fabric and within the reach of the needles for fastening it intothe embroidery. The workmanwho on one end of the machine engages the cord into: said*holder,has to draw the cord out of thebundle, to "carry it over the whole length of the machine and to fasten it at-the other sideof the same; in this way, the cord is brought into its position ready for operation. The modern embroidery machines are in the most cases constructed. only for two embroidery rows and comprise onl a few middle frame uprights, so that in t us following the cord for the lower embroidery row the workman is not seriously hindered thereby. For the drawing-in of a cord for the upper embroidery row, thereis no hindrance at all. This may be the reason why in practice the said operation has hitherto not been considered as troublesome, although the successive drawingdnof thecords in reality gives rise to certain inconveniences. The conditions are, however, different in therecent great and long embroidery machines with a relatively great number of middle frame uprights. Here, the attendant who besides has a great deal to do has not suflicient time for correctly drawing in the cords if he will not temporarily stop the machine. The same troubles arise in embroidery machines wherein the needle sup ports are not fixed to longitudinal beams, but to frame uprights arranged from distance to distance, in which case the workman,.i'n drawing-in the cords, has to take over or around the saiduprights. The object of the present invention is to facilitate the drawing-in of the cords in embroidery machines. According to theinvention, the cord laying-in device comprises in combination. with cord supplyingbobbins removable holders near the ends of the machine, provided with a row1of openings for Specification of Letters Patent.

the introduction of one cord ineacb opening and so arranged as to hold the cords parallel to each other orderly arranged and to allow drawing-in of all the cords at a time from one end of the machine to the other for their easy transferring into operative positlon.

capable of being transferred from one end of the machine to the other and vice-versa.

For-the drawing-in of the'cords, it is advantageous to arra-ngeat the side of the cord furnishing bobbins a guide having a row of openingsfor the parallel drawing-in of the cords, said guide being fixed and preferably drawn into their openings.

While the holders are preferably constituted by rakes having their teeth directed upward for receiving between them the cords,- the aforesaid guide consists preferably of a bar with arow of holes for the drawing-in of the cords so as to prevent them from being lifted out of said holes.

The drawings represent an embodiment of the subject of the invention. Figure 1 is a diagrammatic longitudinal view: of an embroidery machine having fiverows of needles; Fig.2 1s a vertlcal transverse sectlon through "said machlne ona larger scale;

Fig. 3 shows a plan view of one group of cords; Fig. 4 shows by a side elevation one of the cord holders;.Fig. 5 shows by a slde elevation the guide with clamping member and Fig. 6 represents two special, butwell known working tools.

- The uprights a of the machine frame carry the needle bars c by means of the brackets b. Nearthe ends of the machine are arranged two vertical control rods d, e which can be movedthrough the medium of a jacquardor hand-controlled rod 7 and levers g, g interconnected by a link rod iand joined by links it .to the respective control rods cl, 8. The rods d, e-carry arms Z, m, respectively. "On

holding .in parallel tensioned condition the difierent cord groups corresponding to the embroidery rows. Among said holders, that on the right hand placed near the end of the these arms are mounted the holders 0 for machine where cord furnishing bobbinsw e are arranged, serves at the same time for the drawingin of the corresponding cord group inasmuch as the cords thereof'furnished by the respective bobbins and passingthrough a guide p fixed on the arms m are fixed in said right hand holder, and drawn through, its medium over the whole length of the machine from the right-handend to the lefthand end of the same, so that this drawinginof the-cords :is simultaneously and orderly produced at a time-for all cords of the same group. .Eachof the holders 0, see Fig. 4,'consists of azra keo havingits teeth directed upward for receiving between them the respective cords, .andof a fulcrumed clamping cover 0 which can be lowered over said rake 0 and-in the lowered position clamps in all the .cords-lying-in the openingsbetween the rake teeth. -The cord guide p, which is arrangedzon the cord furnishingside of the machine, consists' of two parallel pierced plates 117 see Fig. 15,: and an interposed, tightly .guided pierced slide p whicln after drawing-in the cords through the holes of the plates 39 is sodisplaced relatively to the platesjp as to clamp in or .secure the cords in thedrawing-in holes. Thearms Z, m carry besides each a well known cord-laying-in finger q (Fig.wG) for-*receivingthat cord of thegroup-which is to be transferred into operative position, anda wellIknown cutter 1" (Fig.6) .which isdesignedto cut'ofi the embroidered in cord. As soon as a cord of each group. is put into thegfingers Q on both ends laying-in or stitching to the embroidery fabrie is obtained by lowering the rods d, e through the medium of the lever system '7, 9,19 After the laying-in of the forward cords of the fdiflerent groups into'the embroiderywork, the said rods are again raised by means of the lever system 7, g, g and in this operation'the cutter 1" cuts off the cords held inplace by the embroidery work and in contact-with the inner sharp edge of the operative hook of the cutter, as it iswell known in this kind of machines. The cord ends are then still held fast in the holders 0.

The holders 0 are removably mounted on brackets-.0 which are adjustably fixed on the arnisZ,'m,-so=that they can easily and rapidly be -removs3d therefrom. :This detachable connectionof the holders 0 with their bracketslo is obtained, v=as represented in Fig. 3, by; the arrangement wherein in eachholder a Fiveak curved leaf. spring 0 presses against one edge-of the-base: plateof the rake'o and 'pushesethe samewith its other edge. into;arecurved xpartio of the .bracket'0 If it is 'desired to:.-remov es the=holder, a pressure-is. ex-

erted upon it in the direction toward the spring. .04, which; is then compressed orflat- =.tened,'.. so, that. the base edge of; the rake- 0 drawn successively, but in the desired order through the holes of the guide 1), the slide 19 of which is in inoperative -position,-and then laid on the right hand side-of themachine parallel side by side between the teeth of the respective holdero, wherein they are then clamped fast, whereupon the said holder is removed'from its bracket and utilized for drawing in all the .cords at a time over the whole length of'the machine from one end to the other. After this drawingin the said holder is fixed to the left-hand bracket 0 while on the right-hand side'of the machine there is mounted another similar holder 0 with the teeth of its rake entering from below between the cords of the drawn-in row, whereupon the clamping cover 0 of the second holder is put down to clamp fast the cord in the holder. This second holder gives the advantage that-the cords coming from the supply bobbins, after consumption of the length of cord in opera tive position, are ready and in proper order for their further drawing-on througlrthe machine, inasmuch as for this further supplying operation the said holder may'serve as drawing-in tool. After the slide 17 of the guide 29 has been displaced to clamp fast the cords in the same, the cords of the group are fixed in tensioned condition-and in an-orderly arranged row andthey can then successively be brought into their operative position.
