(01. 242-355) This invention relates to textile machines and et wheels 36, 36 for causing the carrier to is particularly applicable to machines having cirtravel in the path defined by the guideway.

Suitable machines disclosed in the above mentioned patdriving connections for these rolls may comprise ents and applications. Thus in common with the connections described and illustrated in my these machines the present machine includes a divisional Patent No. 1,911,047.

guideway constituted of upper and lower rails The illustrated embodiment of the invention is 50 mounted on upright frame elements, the upper particularly adapted for the winding of headless, rails 4 being shown in the drawings, a plurality self-sustaining Fiji packages or cheeses consistof carriers 10 for the yarn being operated on, ing of layers of reversed spiral windings, with (one only of these carriers being shown in Figs. the cusps formed by the reversals of the spirals 2 and 3), and a drive chain 30 running on sprockdefining the end faces of the package. This man- 55 her of winding necessitates a rapidly moving traverse device adapted to engage the yarn strand Y as it approaches the winding mass. Such a de vice is shown herein as a traverse cam 70 (Fig.2) rotatably mounted between the plates 66 and 67 of the carrier and spirally grooved to reciprocate a cam follower 101, which is slidably mounted on a horizontal rod 100 (Fig. 3), and which carrios an upward extending grooved eye 106 engageable with the yarn strand. Suitable driving connections for the traverse cam may include tires 71 thereon which engage and are turned by drive rolls 50 and 51 successively, as the carrier moves around the guideway.

In the travel of the carriers around the guideway it is desirable to stop the driving of the winding yarn mass and traversing of the yarn so as to permit the performance of replenishment operations with respect to the yarn masses on the carriers, either manually, or automatically as in the machine of Patent No. 1,700,425. Preferably the stoppage of driving for these purposes is controlled by means responsive to the attainment by the carrier of a predetermined point on the guideway, or responsive to the completion by the carrier of a predetermined course of travel. Means for causing such cessation of driving and traversing may comprise a dog 362 carried in an enlarged head 360 of a horizontal shaft 303 on the carrier and adapted to strike in passing, and to be rotated by, a pin 307 extending from the guideway, thus to turn shaft 303 and a crank 302 to raise a lifter rod 301and swing the package carrying arm 71 and package C clockwise (as viewed in Fig. 3) through the full-line position of Fig. 3 into the outermost broken line position of that figure.

As explained in my copending application Serial No. 476,776, the dog 362, lifter rod 301 and their connections may serve also to shift the position of the yarn package upon the occurrence of improper conditions in the winding strand Y. Such improper conditions may comprise for example the appearance in the traveling strand of slubs or imperfections which it is desired to remove, or the cessation of proper travel of the yarn such as evidenced by excessive or insufllcient tension in the strand, breakage of the yarn, or exhaustion of the supply yarn. As exemplifying one type of detector particularly suited to detect breakage or exhaustion, the present machine may be equipped with a. pivotally mounted wire bail 310 normally held depressed by the yarn strand Y, and in such position acting through a link 314 to hold dog 362 in an inclined position. The guide rail 4 of the machine is preferably provided with a number of short pins 318, which are normally cleared by dog 362, one such pin 318 being indicated in Fig. 2. Upon the occurrence of exhaustion or breakage of the yarn, the yamcontacting portion of the detector wire 310 rises, thus permitting dog 362 to drop into a vertical plane. In such position the dog strikes in passing, and is rotated by the next adjacent pin 318, thus actuating the above described connections to cause cessation of driving the package and traversing of the yarn.

Considering now more particularly a carrier reaching the pin 307 disposed near the end of a straight portion of the guideway, (Figs. 1, 2 and 3), the pin 307, dog 362, shaft 303, crank 302 and lifter rod act to swing the package carrying arm and package C clockwise toward the inactive position of Fig. 3; accordingly traversing of the strand ceases. Were the yarn package C to be allowed to rotate after driving stops, (as would normally happen) a strand, no longer traversing, would windabout a single section of I the length of the package, thus producing an enlargement or bung which would destroy the regularity of subsequent layers and impair the compactness and self-sustaining qualities of the package. To prevent this, I provide a package brake adapted rapidly to stop the rotation of the winding yarn package, preferably operable on the package as a consequence of, and during, the shiftingv of the package incident to stopping of driving of the package and traversing of the yarn.

Referring to Figs. 1, 2 and 3, wherein the package brakeis shown in its preferred arrangement as disposed to act on the yarn packages of successive carriers as the carriers are about to leave the end of drive roll 51 in approaching the operators end of the machine, the brake 80 is shown as formed of a sheet metal plate yieldingly mounted to intersect the path traveled by various sized. packages as the packages are swung to their inactive positions. As shown in Fig. 2, the brake .80 is preferably pivotally mounted upon a generally horizontal rod 81 extending generally parallel to the path of the yarn packages, this rod 81 being herein shown as supported by a bracket 82' fastened to the upper rail 4 of the guideway. Preferably the brake 80 is yieldingly held in its lowermost position of Fig. 3 by gravity, the brake having a weight 84 mounted thereon, and is prevented from falling below this position by the provision of a limiting stop constituted of a lug 80 movable with the brake element and adapted to strike a pin 80 fast with the rod 81.

As the carrier reaches pin 307 (Fig. 3) on the guideway, the dog 362-is temporarily retained by the pin and thus causes shaft 303 and crank 302 to swing, lifting the rod 301 and swinging the package-holding arm 71. As the winding package rises from the drive roll 51, the periphery of the package C is rubbed against the weighted brake 80 which quickly stops rotation of the package. 'I'hus'in the illustrated machine but little untraversed yarn is wound on the package after the yarn is disengaged from the traverse eye 106.

In order to permit the brake 80 to be adjusted vertically, or to be adjusted angularly so as better to accommodate conical yarn packages when these are wound, the rod 81 on which the brake is mounted is preferably connected to the bracket 82 by means of an adjustable arm 85 secured thereto by a bolt 86, passing through a slot 87 in the bracket 82. The brake is preferably provided with an inclined extension 88 at itsleading edge as shown in Figs. 2 and 3 adapted to engage the end of the cylindrical periphery of a very'large package which may happen to pass the brake in an elevated or inactive position, so that the brake is lifted by camming action of such a package, instead of being struck at a thin edge of the sheet material. Preferably the free outer edge of the brake 80 is turned up as indicated at 89, to permit the braked package to slide smoothly from under the brake.

By virtue of the pivotal mounting of the brake this device is adapted to operate on packages of various sizes encountered as successive carriers pass with their packages in varying states of completion.

After its rotation has been stopped by the brake 80, the package may then pass a suitable gage 250 which marks it with chalk'or the like if the package has attained full size; then the winding unit may pass a pair of air nozzles 220, 221 which are directed respectively at the traverse eye 106 and associated parts, and'at the guide wires 396, 397, the tension disks 380, 381 and the slub-catching blades 400, 401. After the unit has passed the semi-circular end portion of the guideway, it may pass a lubricator tube 231 carrying a lubricator brush 230 which oils the traverse guide rod 100 and associated parts. Thereupon the winding package may be lowered onto the drive roll 50 and started winding by the mechanism described and claimed in my divisional Patent No. 1,911,047. The aircleaning means and the lubricating means form the subject matter of my continuing applications Serial Nos.
