COP-WIN DING MACHINE.

Application filed April 8, 1927, Serial No.

This invention relates to a cop winding machine of the kind wherein the thread guide is reciprocated by a cam-supported traverse bar and advanced on the latter by 5 means of a progress wheel operated by contact with the cop at the end of the traverse, and the invention consists in the provision of means whereby additional reciprocating movement is imparted to the thread guide independently of the traverse mechanism and within shorter limits in order to lay the yarn in short, open, overlapping spirals on the conical nose of the cop. The additional reciprocating movement may be obtained'either byconnecting the thread guide to a crank element on the progress wheel device, or by adapting the traverse bar for independent movement relative to the trav- .Fig. 1 of the accompanying drawings represents a side view' of the mechanism,

Fig. 16, a section on the line XVI-XVI of Fig. 12, and L Fig. 17, a sectional view on an enlarged scale, of the traverse bar device employed in the modification according to Figs. 12

The machine has a driving shaft 1 which operates a cam shaft 9 by means of a pinion 6 and a gear wheel 7. For each winding mechanism the shaft 1 carries a friction wheel 2 which supports and drives a wind- 'ing spindle 4 through the medium of a The yarn 41 is led from a swift 37 or from a spool 38 tothe thread guide 34 whereby] it is laid on the conical nose of the cop 5.

The thread guide is reciprocated by the cams 10 and the rail 12 along the whole extent a (Fig. 5) of the nose, and it is advanced relative tothe traverse bar 14 by the friction progress wheel 13 which for this purpose contacts with thebody of the co at the end of-the traverse.

lhe mechanism and action so far described is well-known. According to the invention means are provided for, reciproeating the thread guide independently of the traverse rail 12 a plurality of times during each traverse so as to lay the yarn on the nose in short, open, overlapping spirals. The mechanism-employed for this purpose may be constructed in difi'e rent ways. Ac-

cording to Figs. 1 to 6 the driving shaft 1' carries a cam 15 which rocks the lever arm 21 through the medium of a roller 16. The

- arm is' pivoted at 18 to a bracket 20 on the table 19 and is controlled by a spring 22 which holds theroller 16 against the cam.

A rod 23 connects the lever arm 21 with an arm 25 connected to a shaft 24,.and a link 29 connects the arm 25 with an arm 25' connected to a shaft 24'. Thetwo shafts 24 and 24' are mounted one-above the other inf brackets 28 surmounting the table 19. For

each winding mechanism there is an upright shackle 31 which is pivotally held by two arms 26 and 26 mounted on the two shafts 24 and 24 one on each. The rocking movements imparted by the cam 15 and the lever 21 to the shafts 24, 24 causes the shackle 31 to be reciprocated horizontally in a plane at right angles to the traverse rail 12. The thread guide eye 34 is formed on a crank element which is rockingly mounted in an arm 36'of an angle piece carried by the friction progress wheel 33. One arm of this crank element holds the eye 34, another arm 33 of the same being formed with a hook 32 which remains in engagement with the shackle 31 in all positions of the thread guide. The arms 35 and 33 are soarranged relative to each other that the movements of the shackle 31 causes the thread guide eye 34 to reciprocate in the direction of the arrow b (Fig. 1) and lay the yarn in short, open spirals on the nose of the cop. The stroke 0 (Fig. 5) of the guide and thus the angle a of the spiral coils may be varied by connecting the rod 23 to different points on the lever arm 21, the latter being provided with a plurality of apertures 17 for this purpose.-

The angle piece which carries the thread uide element 1s shown on a larger scale in ig. 6. It has a forked arm whereby it is guided on an upright rod 39. The latter allows the angle'piece to follow the up and down movements of the wheel 13 but prevents it from rotating together with the same.

In order to obviate excessive accumulation of mechanisms on the machine table, the device may be modified, for instance as shown in Figs. 7 to 11. In this case the crank element 35, 33 which imparts the additional reciprocation to the thread guide 34 is held in an angle piece 36' and operated by a shackle 31' which is firmly secured to an lipright rod 39. The latter, which takes the place of the guide rod 39 of the previous construction, is formed with a downward I extension 70 whereby it is rotatably held in a boss ,71 secured to the traverse rail'12. A plate 72 on the rail holds the boss and. also the traverse bar 14. A bracket 73 which is secured to the boss 71, carries a bearing 74 for the lower end of the rod extension 70. Between the boss 71 and the bearing 74, the rod extension 70 carries a vane 56 which cooperates with an eccentric or cam mounted on a shaft 54 arranged under the machine table. The shaft 54, which has an eccentric I for each winding mechanism, receives rotation from the shaft 1 through the medium of a round belt 52 and grooved pulleys 51 and 53. Anarm 73' on the bracket 73 and an arm 56' on the vane 56, are connected by a spring 75 which maintains the vane in con-.

' tact with the eccentric 55, the vane being therefore oscillated in the direction of the arrow f (Fig. 11). The oscillations of detrimentally affected by the angular movement of the thread guide, the device may be modified with a view to render the thread guide movement parallel with the winding spindle. For this purpose the arrangement shown in Figs. 12 to 17 may be resorted to. In this arrangement the shaft 54 and the vanes 56 are retained, but the latter are rotatably mounted on reduced ends 57 on bolts 58 which depend from the traverse rail 12. Connected to the vane 56 is a bifurcated arm 60 in the .gap 59 of which one arm 35 01? a bell-crank is engaged. The bell-crank is pivoted at 61 to a bracket 62 depending from the traverse rail 12. The other arm 33 of the bell-crankis bifurcated and provided with slots 63,for engagement with pins 64' atopposite sides of the traverse bar 14 which in this case is prolonged through the rail 12 parted to the'bell-crank 35, 33 which in its turn rcciprocates the traverse bar 14 in longitudinal direction. The thread guide 34 is in this case held stationary relative to the friction wheel 13 in the usual manner.
