SKEINING DEVICE. V

Application filed October 23, 1926, Serial No. 143,629, andin Switzerland November 2, 1925.

The subject matter of the present invention is a device for skeining hanks of yarn on reels, i. e. for subdividing the banks by interlacing a skeinin thread between the leas. In order to simplify the device in comparison to known mechanical skeining devices the device according to the present invention is provided with receiving means arranged within and without the reel and cooperating with holders for the skeining thread, said holders being alternately de-* livered from the inner receiving means to the outer receiving means and vice versa by a relative movement of said receiving means.

Fig. 19 is asection along line IXX--IXX in Fig. 18 with parts shown in an end view,

and

Figs. 2023 show details. Referring now to the first constructional example illustrated in Figs. 1-7 the reel 1 is turnably mounted in pedestal bearings 2 and 3 which are open at the top and fixed on a table 4. The latter rests on rollers 5 turnably mounted in extensions 6 of a table 7 forming part of the frame of the device and being supported on standards 8. The.

table 4 together with the reel 1 is thus displaceable in. the axial direction of the latter on the rollers 'Aiplurality of hanksi) are arranged on the reel and the skeining thread is obtained from bobbins 10 mounted above the reel. Means are providedto secure the reel 1 against rotation and to fix it in different angular positions. These implement meansare illustrated in Figs. 3 and 4 and compr se a disk 11 fixed on the axle 12 of the reel and provided with a number of holes 13. corresponding to the angular positions in which the reel has to be secured. With the holes 13 a pin 14 cooperates, mounted in an arm 15 which is fixed to a gudgeon 16 rigidly held in the pedestal 2. A sprlng 17 urges the pin 14 to engage one of the holes 13 and a lever 18 cooperates with the pin 14 to withdraw the latter and to compress thereby the spring 17 when it is intended to turn the reel 1 and secure it in a different angular position. 19 denotes an organ extending in the axial direction of the reel 1 and provided with prongs 20 adapted to enter into the hanks and to subdivide the latter into a number of leas 9 which haveto be tied together by the skeining thread. The organ 19 is carried by a base part 25 and a clamping member 26 pivoted on the base part at 27, a plate spring 28 presses the clampingmember 26 on the needle 23 (Fig. 6). The needle clamps are fixed on a bar 29 by means of a set screw 30 and are adjustable along said bar 29. The latter is fixed to two supports 31 slidably arranged on horizontal spindles 32 mounted in pedestals 33. A reclprocatmg movement is imparted to said supports 31 and thereby to the needles by means of a cam-disk 34 mounted on the main driving shaft 35. A

groove 36 is provided in one of the end i 'faces ofithe disk 34 and a roller 37 coo erates with said groove. The roller 3 is lever 38, the upper end of which is connected by a link 39 to one of the supports 31. The

lever 38 is fixed on a shaft 40'turnably turnably mounted in one end of a two armed I l) is coupled to an arm l2 fixed to the shaft 40.

In order to open the needle clamps a horizontal rod 43 passes above all the clamping members 26 andis carried byltwo .vertical arms 14i, which are supported by cranks i6 and links 45 between the arms and pedestals 33. The arms id are pulledinthe down t pushed into thereel lbiy hand and the memward direction by means of a cam disk 4t? fixed to the shaft 35 with which a rollertS at the end of a cnank arm 49 cooperates.

which the cranks 16 for the two arms 4% are attached. Uponithe rotation otthe shaft the cam-disk 4.7 "and the roller l8 cause a downward movement of thdar ms 4 1, wheredepressed bar-51 may bewithdrawn from the reel 1 whenthe latter has to heturned. Thesup ports 54; are slidably arrahgechon axles 56 and 56' mounted in pedestals 57. A recipe rocatiirqmotion of the supports 54: in the axial direction of theaxles 56 is caused by the disk 58. having a lateral groove 59 with which a roller 60 cooperates. The latter is mounted in the lower end of a two armed level-61 fixed on a shaft-62mounted in brackets 62 andthenpper end of the lever 61 is connectedby means ofa link 63 to the middle snpport 54 Fig.1). "The outer supports 54 are coniiected to the 1 arms Get onthe shaft 62 by similar linksGS. Acollar 65 limits the endivise extren'ie position of the bar 51 so that the apertures52 are exactly opposite the needle-clamps when the bar 51 is manually pushed into the reel.

The means for displacing therecl 1in the axial direction eomprisea pinion 66 fixed to the main driving shaft 35 and cooperating with a gear wheel 67 mounted on a countershaft 68 On the latter a driunGQ is fixed provided with a can] groove 70 onits circumference with which'a roller 71 eooper "ates; The roller 71 is turnably mounted in i the lower end of a two-armed lever 72 piv-K otednt'id ina bracket T3, the upper end of this leverTQisconnected b uneans of a 1 link 75 to a bracket- 76 fixed to'the lower side otthe table 4 on which the re ell is mbiinted: A turning of the drum '(39 causes arbiprbcating movement of the table 4 and thereby otthe reel in the axial-direction of thelatter. 77 denotes the driving pulley.

The reel 1 is placed from above into its 1 bearings of the pedestals 2 and 3 andfixed in the desired position by causin the pin 14 to enter one of the holes 13. 'fhereupon the bar 51 for receiving the needles 23 is berla is swung towards the reel so that its prongs 20 penetrate through the hanks 9 and subdivide the latter into ileas" 9"; the

prongs thus forming openings necessary for thepaesage of the needles. n 1 pp Then 12118 needlesrilfi held by the :needlei clan'ips outside of the reel hare threaded with the skelnlng thread from the bobbins 10 and the driving shaft 35 lSICRI1SGdlO ro J i;

tater By tlie ac tion of thecam disk 34 and the parts operated therefromthe needle clamps are moved towards the reel 1 and sit-1: inultaneously the bar 51 is moved towards i the needle clamps and receives theneedles. The holding members 26 aredepressed and the needles are released and drawmthrough the banks by the receding bar 51. When.

the latter has reached its extreme position it moves towards the needle clamps and in the mean time the reel has been displaced in the axial" direction by theuaction of the drum 69 and the parts cooperating there with, so that the needle held by bar 51 is opposite thenext opening as is shown in Fig. 9. The needles are partly pushed :1

through the bank by the bar 51 and are received hy the needle clamps, as the latter;

and the bar 51 more simultaneously towards and away fromieach other, the cam grooves wand--59. being opposedto each other. Tllhe holding members 26 are released by the bar 43 wherebythe needles 23 are again held by drawn through the banks by the clamping the clamping memhersand are completely members moving away from the reel and the latter is further axially displaced so that a needle occupies the position illnstratedin Fig. 10. The above mentioned movements of the bar 51, of the needle clamps and of i the reel continue and :the following positions of oneneedle relatively to the hank lli shown in Figs. 11 andlQ. The reel is then axially displaced in theopposite direction to i which it moved previously and the needle :1 occnpies suocessively the positions shown in:

When 't is desired to skein the bunks also. i

at other parts of the circumference ofthc reel, the latter is turned into the desired position and the above descnbed operhtions out The second constructional example illus are contihued with the reel in the new posi JUL of the bar 51. WVith the first constructional example the bar 51 had to be withdrawn in the axial' directionfor permitting a removal or a turnlng ofthe reel, whilst in the second constructional example the bar 51 is so arranged that it remains in the reel 1 when the latter is removed. To this end the bar 51 is carried by means of axles 78 slidably mounted in brackets 7 9 fixed to the axle 12 of the reel 1. The axles 78 are provided with angular heads 80 in which the bar 51 is carried by set screws 81, Figs. 22 and 23. In order to permit the axial displacement of the reel 1 relatively to the bar 51 a slot 82 is provided so that the angular head 80 may slide on the bar 51 without being hindered by the set screw 81 when the reel 1 is displaced. Coil springs 83 are connected with their one end to the bar 51 and with their other end to the angular head 80 to provide for a resilient connection between the latter and the bar 51.

The bar 51 is of such a length that its ends are loosely inserted in heads 84 of the axles 56 (Fig. 21) which are slidably mounted in the pedestals 57. The reciprocating movement of the axles 56 and thereby of the bar 51 towards and away from the reel 1 is caused by similar means as in the first constructional example, of which the two-armed lever 61, arm 64: and the link 63 are shown in Figs. 18 and 19. The reciprocating movement of the table 4: relatively to the table 7 is also caused by means similar to those described above with reference to the first constructional example and of which the upper end of the two-armed lever 72 and the link are shown in Figs. 18 and 19. The clamping devices for the needles and their operative connection to the driving shaft are not illustrated in this constructional example as they are similar to those of the first constructional example.

The skeining device according to the present invention is of a simple design and it ensures a reliable operation and a high output.
