YARN CLEANER FOR SPOOLERS.

This invention relates to a yarn cleaning and guiding mechanism for use in a spooler Such a spinning or other similar machine. device is employed for cleaning or removing from the yarn or thread slubs, beads or bunches of fibre and for properly guiding the yarn in its passage to thecleaner and to the yarn receiver upon which it is-wound.

The object of the invention is to provide a simpleand eflicient form of cleaner which may be readily and accurately adjusted in order to secure the proper positioning and spacing of the comb teeth with respect to the guide rod over which the yarn passes.

The object of the invention is further to provide a simple and eflicient form of cleaner in which the comb may be readily swung away from the guide rod to permit removing the slubs, etc.,.from the yarn teeth and in which the comb may be swung back to oper at-ive position all without disturbing its adjustment.

The object of the inventionfisf further to provide such a yarn cleaner comprising a support having an upward andrearward inclined face on which the comb member is pivoted, together with adjustable means for limiting the downward swinging'movement of the comb member.

The object of the invention is further to provide a novel and eflicient means for effecting avertical adjustment of the guide rod in its bracket andalso for indicating its adjusted position.

The object of the invention is further to provide a yarn cleaner and tension devicein combination with a two-part bracket clamped upon the traverse rod of the machine.

These and other objects and features of the invention will appear more fully from the accompanying description anddrawings and will be particularl pointed out in the clalms.

The drawings i lustrate a simple and preferred form of the invention as adapted for use upon the ordinary type of spooler.

In the drawings:

Fig. 1 is a side elevation of the device with.

the traverse rod of the spooler shown in cross sect-ion.

Fig. 2 is a view similar to Fig. 1 looking at the opposite side of the device.

Fig. 3 is a top plan view of the device. Fig. 4: is a perspective view of a split bushing employed in the yarn cleaner.

The device of this invention is shown as adapted to be carried by a traverse rod 1 of a spooler. spinning or similar machine in which the traverse rod commonly has a vertical reciprocating movement'to lay the yarn throughout the len th of the yarn receiver as it is being woun thereon. In such a device it is necessary to provide means for clean-' ing or removing from the yarn any slubs, beads or bunches of fibre which occur and which would injure the quality of the yarn if carried on to the receiver and also it is desirable to provide suitable guides for directing the passage of the yarn tot-he cleaner and suitable means for applying the required amount of tension to the yarn, thus to insure its even and steady movement duringthe winding or other operation.

One feature of this invention consists in providing a two-part bracket, one part of which supports the cleaning device andv the other part of which supports the tension device and suitable guides with this bracket so constructed that the two parts may be rigidly clamped together upon the interposed traverse rod. There is thus presented a very simple andefficient-construction upon one part of which any desired form of cleaner may be mounted and upon the other part of which any desired form of tension device or guide may be mounted. Such a bracket com-- prises the part 2 having at its front face a substantially semiscircular recess to fit against the traverse rod 1 and the part 3, having at its rear face a substantially semicircular recess to fit against the traverse rod 1. These bracket parts have opposed vertical faces and downwardly extended flanges. A clamping bolt 4 passes through the flange of the part 3 and is threaded into the flange of the part 2, thus enablin the two parts of the bracket to be clamped rigidly together and also rigidly to the traverse rod. The part 2 is shown as carrying the yarn cleaning device and the part 3 as carrying the yarn tension and guiding devices. This enables the clamping section of a usual yarn cleaner bracket to be removed and a bracket part provided with a tension and guiding device such as that illustrated to be substituted therefor and clamped to the usual yarn cleaner bracket. It also enables the tension and guiding devices to bechanged, if desired, by substituting bracket parts carrying other forms.

The present invention also presents a novel form of a yarn cleaner. The bracket 2 is provided with a guide rod 5 projecting laterally therefrom and over which the yarn passes. This guide rod is mounted in the bracket so as to be readily and accurately adjusted vertically therein and the means provided for this adjustment is arranged to effect a visual indication so that the vertical position of the guide rod may be readily and accurately ascertained. For this purpose a split bushing is mounted for rotary adjustment in a bore in the bracket part 2. The bore 6 of this bushing is eccentric to the bore of the bracket in which the shank 7 of the bushing its and the guide rod 5 fits snugly in this bore and is held from longitudinal movement in the bushing by a small set screw 8 threaded radially into the bushing and engaging at its inner end a circumferential groove in the guide rod. A set screw 9 is threaded. into the bracket radially of the bushing and engages at its inner end a circumferential groove 10 on the bushing. It will thus be seen that by loosening the set screw 9 the bushing may be retated in the bracket, thus varying the vertical position of the guide rod owing to the eccen tricity of the bore 6 of the bushing and that when the guide rod is in the required vertical position, it may be clamped firmly in place by tightening up the set screw 9 which both clamps the bushing against the guide rod and clamps the bushing to the bracket. Before the parts are clamped in position, the guide rod may be rotated in the bushing without changing the adjustment to cause its outer angularly disposed end 11 to assume the desired position. An arcuate scale plate 12 mounted on the side face of the b .acket and the set screw 8 serves as an indicating finger or pointer cooperating with this scale plate so that the vertical position of the guide rod is visually indicated thereby. Stop pins 13 may also be provided to limit the extreme positions of adjustment by the engagement of the set screw 8 therewith.

A second guide rod 14 is usually provided projecting laterally from the bracket in the rear of and parallel with the guide rod 5.

The bracket is provided with an upstanding support 15 herein shown as an integral part of the bracket and presenting at the front an upward and rearward inclined face 16 parallel with the guide rod 5.

A comb member herein shown a flat blade 17 having at its lower edge comb teeth 18 secured thereto is pivoted by means of a screw 19 to the support 15 so as to swing on and be guided by the face 16 into and out of cooperative relation with the guide rod. The upward swinging movement which may be limited by a small pin 20 projecting from the plate 17 engaging the support 15 is for the purpose of enabling ready access to the comb teeth 18 so that the operator may remove the slubs, etc, collected thereon. It is very important that the comb teeth, when in in the other direction is secured by limiting the downward swinging movement of the comb member. This last adjustment is preferably secured by a set screw 21 threaded through the bracket, locked in position by a lock nut 22 and abutting at its inner end a.

shoulder on the blade 17. It will thus be seen that the adjustment and spacing of the line of comb teeth with respect to the guide rod 5 is accurately and readily determined in every respect. l r

The comb member is preferably held in its normal operative position against the set screw 21 by a spring. The operative may readily swing the comb member to cleaning position against the tension ofthis spring, but this spring insures automatic return of the comb member to operative position. A suitable helical spring for this purpose is shown at 23 seated in the support 15 surrounding the pivot stud 19 and engaging at one end the head. and at the other end the comb member. It will be observed that the axis about which the comb member 17 swings, in moving from its operative to its cleaning position, and vice versa, extends transversely of or at right angles to the cooperating guide rod 5 and that this is quite independent of the inclined feature of the supporting face 16, the only requirement in order to secure parallelism between the comb teeth and the guide rod in this respect being that the face 16 shall be parallel with the guide rod 5. q

A suitable guiding means is provided on the bracket part 3. As illustrated, this bracket part is provided with a forward extending, forked, yarn guiding extension 24, at the throat of whichis mounted a transverse vitreous pin 25, over which the yarn passes. The bracket part is also provided with a laterally extending support herein shown in the form of a looped rod 26. A. portion of the bracket part 3 extends beneath this looped rod 26 and has mounted therein a vertical stud 27. On this stud is loosely mounted a disk 28 having a downwardly and inwardly bevelled periphery 29 and a hub 30 extending downwardly between the members of the looped rod 26. This diskrests freely on the members of the looped rod 26 and consequently on the yarn 31, which after passing over the vitreous pin passes over the rod 26 on its way to the yarn cleaner. The hub also acts as a moving lateral guide for the yarn. The weight of this disk may be varied in any suitable manner to produce the required pressure upon the yarn and consequently the required tension.

A guide plate 32 is secured in position by lock nuts 33 threaded on the upper end of the stud 27 and is so positioned that its lower edge extends midway vertically of the disk 28, thus, in connection with the bevelled periphery 29, enabling the yarn to be threaded into position.
