My invention relates to improvements in cop frames, and more particularly in the construction of the thread guiding means. The object of the improvements is to provide thread guiding means which are simple in construction, and in which the reciprocating masses are exceedingly small, so that the winding efiiciency is high. With this object in view, my invention consists in mounting the thread guiding means on a rotary shaft located parallel to the axis of the cop tube, the said thread guiding means comprising a sleeve slidable and non-rotatable on said shaft and carrying an operating member or members and acting on an arm rockingly mounted on said sleeve and carrying the thread guide which is adapted to move in a plane parallel to the axis of the cop frame.

For the purpose of explaining the invention several examples embodying the same have been shown in the accompanying drawings in which the same letters of reference have been used in all the views to indicate corresponding parts. In said drawings Fig. 1 is an elevation showing the cop supporting means and the thread guiding means,

Fig. 5 is a sectional elevation on an enlarged scale, taken on the line 5-5 of Fig. 4,

Fig. 7 is a view similar to Fig. 6 and showing a modification.

Referring now to the example shown in Figs. 1

to 3, the cop supporting means and the means for operating the thread guide are mounted in plates 40 and 4 I. The cop supporting means comprise a spindle 2 rotatably mounted in the plate 40 and a counterpunch 3 mounted in the plate ii, the said spindle and counterpunch 3 clamping the cop tube 39 between the same as is known in the art. The spindle 2 is adapted to be rotated from a friction disk 4 through the intermediary of gear wheels 5 and 6. Parallel to the axis of the cop tube 39 a shaft l is rotatably mounted in the plates 4|! and M, which shaft is driven from the disk 4 through the intermediary of gear wheels 8 and 9. Further, a screw thread spindle l! is mounted in the plates 40 and 4| which is drige izg from the shaft it through gear wheels 31 an On the shaft 7 a sleeve I2 is mounted which is longitudinally slidable and rotatable in unison with the shaft i, a feather key l3 being provided which engages in a longitudinal groove Id of the shaft 77. The sleeve I2 is made integral with a disk It which carries operating members Ii. In the construction shown in the figures the said operating members comprise pins 62 having rollers I! mounted thereon. On the sleeve l2 a thread-guide carrier in the form of a block I5 is loosely mounted which does not take part in the rotary movement of the sleeve I 2, a bushing i8 of lubricating material being provided between the said parts to reduce friction. The block it is held in position on the sleeve by means of a split ring 2!] clamped on the sleeve by means of screws I9. The block 65 is provided with a pair of arms i6. straddling the spindle ii, so that the block i5 does not take part in the rotary movement of the shaft 7 and the sleeve l2.

The block it is provided with a transverse bore 33 in which a tubular member 2i is fixed, the said member being held in position by means of a screw 22 clamping the split top part of the block l5 together. In a bushing 23 fitted in the tubular member 2i 2. spindle 24 is rockingly mounted which is held in position within the bushing 23 by means of a ring 33 fixed to the inner end thereof. The bushing 23 is fixed within the tubular member 2! in a suitable way for example by means of a screw 44. At its outer end the spindle 26 is formed with a head to which an arm 25 is secured, which is formed with an angular portion 29 extending into position for engagement with the rollers H. To the arm 25 a thread guide 26 is secured which, preferably,

engages in a groove 28 made in the arm 25, the said thread guide and arm 25 being held in position on the spindle 24 by means of a nut 21. By the construction described the thread guide 26 and the arm 25 may be readily mounted and dismounted. To reduce friction, the bushing 23 consists of a material having lubricating property, and the spindle 24 is supported at its inner end on a ball 32.

The arm 25 is formed with a flange 3i disposed goncentrically of the end of the tubular member the and between the said tubular member and flange a spiral spring 30 is located which is fixed with its opposite ends respectively to the flange and the tubular member, the said spring urging the thread guide 26 in one direction and in opposition to the action of the rollers ll thereon. Thus the thread guide is adapted to be reciprocated by the combined action of the rollers II and the spring 30,

For shifting the thread guiding means longitudinally of the cop tube, the block I is provided with a blade 34 engaging in the screw threads of the spindle l1.

The operation of the thread guiding mechanism is as follows:

The spindle 2 is rotated from the disk 4 through the gear wheels 5 and 6, and, further, from the said disk rotary movement is transmitted to the shaft 1 and the screw threaded spindle H. The rotary movement of the shaft 1 is transmitted to the sleeve l2 and the rollers II which act on the angular portion 29 of the arm 25 and impart reciprocating movement thereto and to the thread guide 26, the return movement of the said thread guide being effected by the spring 30. The block I5 does not take part in the rotary movement of the sleeve l2 because it is held in position by the arms l6 bearing on the spindle ll. As winding continues the block l5 and the thread guiding means carried thereby are slowly shifted longitudinally of the shaft I4 and thecop tube 39. The block l5, mounted as it is upon sleeve l2, carries the sleeve l2 with it in its advance upon the shaft.

The shape of the face of the portion 29 of the arm 25 which is engaged by the rollers II is such that uniform movement is imparted to the thread guide, and the thread is uniformly wound into a cop. Preferably the rollers II are disposed different distances away from the axis of the shaft I in such a way that at the outer end of the cop the threads of the successive layers are deposited one beside the other, the said thread guide being moved to slightly different end positions. In lieu thereof the rollers ll may be made with different diameters.

In the construction shown in Fig. 3 two rollers ll are provided on the disk i0. But I wish it to be understood that my invention is not limited to this construction. In Fig. 6 I have shown a modification in which three roll-ers II are provided.

In Fig. 7 I have shown another modification in which the disk I!) carries a cam disk 5| which engages a roller 36 mounted on the arm 25, 29.

In Figs. 4 and 5 I have shown another modification. The main parts of the mechanism are the same as those described with reference to Figs. 1, 2 and 2a, and the same letters of reference have been used to indicate corresponding parts. However, the mechanism for shifting the block l5 longitudinally of the shaft 1 is constructed in a different way. As shown, the screwthread spindle 52 is non-rotatably mounted in the plates 40 and 4|, and on the said spindle an internally screw-threaded disk 35 is provided which bears with its outer circumference on the surface of the cop being wound. The said disk is rotatably mounted upon an arm 53 that extends from block l5 and loosely encircles the spindle 52. The rotation of the cop l is transmitted to the disk 35 which is thereby advanced on the stationary screw-threaded spindle 52 and carries along the block l5.

While in describing the invention reference has been made to particular examples embodying the same, I wish it to be understood that my invention is not limited to the general arrangement of the apparatus and the construction of its parts shown in the figures. For example, I do not limit myself to the construction shown herein in which the cop is located horizontally. Further, I do not limit myself to the construction of the mechanism for shifting the thread guiding means.
