HANY, A CORPORATION F GERMANY DEVICE :FOB MECHANIGALLY LACING BANKS 0F YARN A 'Application led January 8, 1931, Serial No. 506,379, and in Germany July 89, 1929.
Originally the skeining of yarn hanks was effected in a sim le manner by hand. The hank was divid b hand or by means of a lacing comb and t e lacing thread drawn through first in one and then in other direction, zig-zag like, and the ends securely V knotted so, that a cross-wise binding, from anyV runnin knot, was formed. Ihis process had the disadvantage of being tlmeconsuming to a considerable extent.
The subject of this invention is a mechanical lacing device which ensures a lacing free from running knots, and which, at the same time, operates in a thoroughly reliable and trouble-free manner and is of simple construction. The device consists of two slide members arrangedon a supporting plate which are positively interconnected 1n such a way that when one moves upwardly the other moves downwardly. Each slide member is provided with downwardly directed dividing members. During the motion of the slide members the hank is alternately formed into a shed. Immediately adjacent and parallel to the said dividing members a swinging needle member is arran ed which ides the lacin thread throng the sh formed. The ividing members may consist of tongueshaped prolongations of the slide members which are notched at their ends for receiving the part-banks and are so arranged with respect to one another that the tongues of the' one slide member cover the gaps formed by the tongues of the other slide member.
In order to facilitate the division of the hank and to maintain the same division during the reverse motion of the slide-members it is advisable to arrange a special comb for the slide members. The prongs of the comb 40 project out over the tongues of both dividing members so that on insertin the device first of all the bank is divided andL thereupon only during the motion of the slide members the part-banks are alternately stretchedl by the notches of the tongues,so that a shed is formed each time and the intermediate s aces which are produced permit the lacing t read to be smoothly passed through on practically a straight path. During 4the reverse motion following the first passage of the lacing thread the prongs of the comb remain in engagement, so that a sure maintenance of the same part-bank is ensured.
Preferably each rong of the comb has a rota slider provi ed with a nose.A In the starting position the nose of the slider lies in the direction of the threads; since it is narrower than the rongs it does not disturb the division of e hank when the device is inserted. Only after the part-banks have been moved does the rotary disc actuate and the nose slides positively in the space between the art-banks as a result of which an depen ing threads of the upper part-ha are raised and united with the same, so that the needle device can pass freely through.
The dividing members may, however, also be constructed as separate dlviding pins arranged on the sliding members. They oonsist of two halves which accurately flt on to` one another throughout their whole length. Each half is provided with two transverse fingers disposed one above the other, the distance apart of which is adjusted to the thickness of the hank to be laced. Each dividing member is provided at its upper end with an annular groove or a collar and the slider plates are provided with a number of suitably constructed'union members corresponding to sie number of dividing halves, which 8 embrace each annular groove or collar on both sides. The individual dividing members are rotatably mounted between these union members; for the purpose `of rotation they have 85 guiding members, provided with pinions, in which they are radiall secured but are axially displaceable. common movable toothed rod produces rotation of the inions of the dividin member guides, an consequently of the ividing members themselves.
` brace only one dividing hal Between two dividing members consisting of the movable halves a simple dividing pin is arranged rigidly on the supporting plate.
In the position of rest the slide membersv are in the mean position; the dividing plane of each individual dividing member is parallel to the plane of the sliding members. The connecting members of each sliding member embrace the annular groove or the collar of each dividing member in such a way that that the dividing members can be smoothly inserted into the hank. B displacement of the toothed rod the divi ing members are rotated by way of the pinions and the guiding members in such a way that each of the 2 connecting members of the sliding members on the two sides of the dividin members em- During the motion of the sliding members the halves of the dividing members provided with lingers disposed transverse to the henk are moved upwards and downwards, res ectively. In this way,-by the upward and ownward motion of the part-banks a shed is again produced, through, which the lacing thread is guided by means of a needle arrangement.
Since the shed is particularly well formed in consequence of the upward motion of the separate part-banks, the passage of the needle arrangement is effected without any trouble,
even in the case of yarn which is little suited for lacing. Y
The invention combines in itself several advantages. The cross-wise union, free from running knots is as yielding as the hand lacing referred to in the introduction; the hank may be loosened without any further preliminary to such an extent that it completely occupies the whole width of the lacing thread This represents a very considerable advantage, not only in dyeing but also in sorting. On the other hand the part-banks in the lacing thread may be readily pushed together, which is advantageous when making bundles for transport purposes. Consequently the lacing device shows the further advantage that, in contradistinction to the known device, it permits simple and troublefree insertion and withdrawal after lacing u has been elected.
The drawings show two constructonal forms of the invention by way of example.
Figure 1 shows in elevation a lacing device, in which the slide members are conc; structed as dividing members at their lower ends, in the first phase of the lacing process and with the lacing comb inserted in the yarn.

Figure 14 shows a side elevation of Figure 13.
Figure 15 shows a second shed, likewise with the needle arrangement passing through vthe same.
Figure 16 shows a side view of Figure 15.
The device consists of prongs 1 of a comb attached to a supporting plate 14 and two slide members 18, 19, rovlded with notches 7 8, which slide in guides 15 of the carrying plate 14 and longitudinal grooves 16 in the prongs 1. The slide members 18, 19 are connected with a double-armed rocking lever 9 by way of links 17, which lever alternately moves one slide member u wards and at the same time the other sli e member downwards. The prongs 1 are rovided with apertures 2 having slots 4. needle ,device 10 moves over a circular path through the said apertures 2. Further on the prongs 1 rotary slide members 20 are arranged in guides 21, the said slide members being provided with a nose 20. Finally, on the carrying plate 14 there is a thread clip 11 and a threadknotting device 12, 13.
During the lacing operation the device is inserted into the hank with the pron s 1 and the noses 20' of the rotary slide memgbers 1ying in the direction of the part-banks, the `hank being thereby divided into separate part-banks. At the same time the slide member 19 resses the two hanks 5, 5 in a downward irection, the hanks 6, 6 remaining above, so that the apertures 2 in the prongs 1 are free, and the needle arrangement 10, known in itself and moving over a circular path, can draw the thread through (Figure 3) Before the needle arrangement 10 penetrates the apertures in the prongs the a toothed rod 32.
assume rotary 'slide member 20 has been positively rotated through 90 in the space between the lpart-banks, and in this way has lifted any depending threads, belonging to the u per part-bank up to the same, as a res t of which the needle arrangement 10 has a free passa e for its motion. The end of the threa 3 which is now drawn through the shed is secured by a clip 1 1, whereupon the needle arrangement 10 and the rotary slide member 20 return to their initial positions. Hereupon the two slide members 18, 19 interchange their position, so that now the hanks 6, 6' are moved downwardl and the two hanks 5, 5'. are moved upwa ly (Figure 4). In this way the lacing thread 3 takes up a zigzag position about the individual hanks. Before the lacin thread 3 isI again drawn through the han s by means of the needle arrangement 10 and is knotted at its end by means of a knetter 12 and -tightening device 13, known in themselves, the nose 20' rotates a second time withimthe space between the part-banks. After the return of the needle arrangement 10 and the nose 20' the device may now be withdrawn from the hank without any difficulty since the lacing thread 3 can readily leave the aperture 2 by way of the slot 4. As is seen in Figure 7, no running knot is in the lacing thread at the places of separation of the individual hanks, but the thread asses uniformly once over and once under t e individual part-banks. Y
In Figures 8-16 a further constructional form of the lacing device is shown. Two slide plates 18, 19 are arranged in guides 15 on the supporting plate' 14; these slide plates are interconnected with a double armed lever 9 by way of links 17. On the slide plates 18, 19 connecting members 22, 23 and 22', 23' are alternately arranged; the said connegting members embrace' an annular groove on the dividing pins 24, 25, 24', 25'. The dividing pins 24, 25 and 24', 25' are divided along their whole length into two halves and they move in guides 26, 27. The dividing pins are revented' from rotating in the guides 26, 27 y means of pins 28, but they are capable of being displaced in the ides in an aXlal direction. Each dividing alf is provided with two fingers 29, 30 and 29', 30'. The guides 26, 27 carry toothed pinions 31 at the to said pinions engage in n addition, between the two dividing pins 24, 25 and 24', 25' a solid dividing pin 33 is provided. For the purpose of extreme limltation of the yarn hank tongues 34, 34 are arranged on the support# ing slate 14. The manner of operation of thls evice is as follows:
Before introduction into the hankv the dividing pins 24, 25, 24', 25' are so positioned by means of the toothed rod 32 that the finers 29, 30 and 29', 30' are parallel to the ank. The lacing device is now inserted transversely to the hank, as a result of which the part- hunks 5, 6 and 5', 6 are formed. Hereupon the dividing pins 24, 25 and 24', 25' are rotated by means of the toothed rod 32, by way of the toothed pinions 31 and the guides 26, 27, so that the lingers 29, 30, 29', 30' embrace the separate part-banks, and, therefore, are situated transversely to the individual part-banks. For the purpose of effecting the lacing, an upward or downward sliding of the slide plates 18, 19 is produced by rotation of the double armed lever 9, whereupon, in consequence of the connecting members 22, 23 and 22', '23' the dividin halves 24, 24 are moved downwardly an the dividing halves 25, 25' are moved upwardly. As a result of this operation a double shed formation takes place: it is impossible for individual threads to depend, since the art-banks are completely embraced by the ngers 29, 30. 29', 30 (Figure 13). After this the lacing thread is carried through the shed by means of the needle arrangement 10. After the return of the needle arrangement 10 the slide plates 18, 19 are moved in opposite directions by means of the double armed lever 9 so that now the two dividing halves 25 and 25' are moved downwardly and the two dividing halves 24 and 24' are moved upwardly, whereby a shed is formed which is the reserve of that just mentioned (Figure 15). Hereupon the second half of the lacing thread is passed through the shed by means of the needle arrangementlO, after which the two ends of the thread are knotted in the 'known manner by means of a knotting arrangement and are cut off. After the return 0f the needle arrangement 10 the lacin device is again brought into the position o restshown in Figure 8 and then withdrawn from the hank, the lacing is then completed as is seen in Figure 7.
