YARN PACKAGE AND THE LIKE AN D METHOD AND MECHANISM FOR WINDING IT.

Specification of Letters Patent.

Patented Dec. 13, 1921.

Application filed April 14, 1920. Serial No. 373,950.

To all whom it may concern Be it known that I, THOMAS ANDREW, a subject of the King of the United Kingdom of Great Britain and Ireland, and resident of 492 Manchester road, Rochdale, in the county of Lancaster, England, have invented new and useful Improvements in Yarn Packages and the like and Methods and Mechanism for Winding Them, of which the following is a specification.

The object of this invention is to make more easy, convenient and expeditious than it has hitherto been the attachment of the last wound end of the yarn of one yarn package to the first wound end of another for the placing of yarn packages one after another in creels with the beginning of each attached to the end of another and the continuous running oil or unwinding of one yarn package after another. To this end, the invention consists in a method and means for winding yarn packages, which are provided with securely fixed coils wound on the yarn holders, previously to the ordinary windings or coils at the first wound portions of the formation in ring spinning machines, ring doubling machines and other machines having ring rails or other yarn guiding means moved like ring rails.

In the accompanying drawings Figure 1 is a diagrammatic side elevation of the lower part of a bobbin with yarn wound upon it below and previously to the ordinary windings forming the bottom of the bobbin and Figs. 2 and 3 are respectively a side elevation and a transverse section of a portion of a ring spinning machine suflicient for the illustration of the mecha nism provided according to this invention. Fig. 4 is a detail of the sector and its adjacent mechanism.

Fig. 1 shows an end 1 of yarn led to the yarn holder, as secured in position by a downwardly wound coil 3 being first wound on the yarn holder 2 and then an upwardly wound coil 4 being wound over it and the end 5 of yarn extending from the upwardly wound coil 4 being led to and wound in the bottom 6 of the ordinary windings of yarn on the yarn holder 2. By a suitable number of turns being included in the down wardly and upwardly wound coils 3 and 4 any length of yarn requisite may be pro vided for facilitating the connection of the end first wound upon one yarn holder to the end last wound'upon another in order that the yarn holders may be mounted in creels and unwound successively in the manner hereinbefore mentioned. By the ends 1 and 5 of yarn being secured respectively by the coils 3, 4 and by the ordinary windof the bottom 6 of the yarn package on the yarn holder 2, the coils 3, 4 are themselves secured in position on the yarn holder 2 so that the end 1 is kept in position to be found easily and the length of yarn for the connection of one yarn package to another is retained on the yarn holder 2 and preserved from unwinding or breakage in the handling or carriage of the yarn packages until required for use.

Coils or windings of opposite hand are wound one to overlap another on. yarn holders previously to the commencement of the coils or windings of the bottoms or like parts of yarn packages, such as bobbins, so as to be on parts of the yarn holders to project fromthe completed yarn packages at the ends at which winding was begun, so that the earlier wound coil or winding secures the end of yarn first led tothe yarn holder and is itself securedby a later coil or winding of opposite hand and the last overlapping coil is secured by the yarn forming its end portion extending into the bottom or likebasal part of the age.

The winding of the coils or windings of opposite hand on portions of yarn holders to project from the ends of yarn packages where the winding thereof begins may advantageously be eii'ected after empty yarn packages have been applied to spindles on which coils or windings have been wound in the ordinary way preparatory to'the deifyarn packmg or removal of completed yarn packages.

Further according as an example of the way of carrying it into effect, the usual device which is movable for lowering a ring rail in orderthat yarn may be wound on spindles below the bottoms of yarn packages, is employed and made to occupy for a short time prior to the commencement of the bottoms or'like parts of yarn packages, a position intermediate between that in which windings on ,the spindles below the yarn holders is eiiected and the position occupied by it for winding of yarn packages.

As shown in Figs. 2 and 3, the usual toothed sector 7 with a pulley 8 guiding a chain 9 used in working the ring rail 10 to this invention and yarn packages are and movable into one position for winding of yarn onto yarn holders in the winding or formation of yarn packages in the ordinary way and into another position for yarn to be wound on spindles below the bottoms 6 of yarn holders in preparation for the removal of completed yarn packages, is contrived to be put for a time in an intermediate position for yarn to be wound on the yarn holders below where the bottoms 6 of to be formed in the ordinary working of the ring rail 10.

To. enable the sector 7 to be put into the intermediate position it is provided with a dog or projection 12 with two places 13, 14 for engagement with the catch 15 which serves ordinarily for holding the sector 7 in position for the winding to proceed in the ordinary way. 7 r

The catch 15 is shown as a pivoted lever with a second arm 16 to arrive on the bracket 7 or part 17 on which the catch 15 is mountbeing wound too high.

ed and so to prevent the catch 15 from escaping from the dog or projection 12 by movement in the direction indicated by; the arrow 18. The catch 15 is shown asprojecting rearwardly in Fig. 2 as a, hook to act as a stop for a projection 20 formed on the sector 7 so as to prevent such sector 7 from When the sector 7 is-in an intermediate position it is preferable that the cam 21 for efi'ecting the upward and downward movement of the ring rail10 should be brought to rest in a :desired position such that in -further movement it will first lower and then raise the ring rail 10. Forthis to be done in the case illustrated, the cam 21 is provided with a striking part 22 shown as a stud or projection in a suitable position'and a lever 23, with a treadle 24 and a. projection 25 preterably adjustable, which by "depression of the treadle 24 can be brought into the path ofthe-striking'part 22, is connected by a rod 26 to a lever 27 made'so to work an engageable and disengageable clutch 28 ordinarily serving to transmit motion to the cam 21 that when the treadle 24 is depressed rail 10. V

the clutch 28 is disengaged to allow the cam 21 to be moved to the position intended by its, own weight or the weight of the ring A spring 29 for engaging the clutch 28 and raising the treadle 24 is connected to the lever 27 and the adjacent side frame of the machine. 7

In the case illustrated a shaft 30 and bevel wheels 31, 32 are used to drive the cam 31 and the clutch 28 is used for effecting con-.

nection and disconnection of the shaft 30 with and from the worm wheel 33 and worm' V 34 for driving it. It will be seen from the drawings that the cam '21 works the ring rail 10 in the ordinary way by means of the bowl 35, 36,'barrel 37 and chain 38 and 10 for the cam 21 to cause yarn to be wound V on'the spindles below the bottoms of yarn holders 2 in the ordinary way.

When the catch 15 ismade to bear against V the surface 13 of the dog or projection 12, the sector 7 and pulley'8 are held in position for the'cam 21 to wind yarn upon the yarn holders 2 in the ordinary way at the bottom thereof and higher thereon according as the chain 9 is unwound from or wound less or more onto the barrel 37. The surface 14 on the dog or projection 12 is formed a little higher than the surface 13, consequently when the chain 9 is wound off the barrel 37 engagement of the catch 15 with the surface 14 will enable the cam 21 to bring about movement 01": the ring rail 10 for winding yarn upon the yarn holders 2 below the place at which the'ordinary bottoms of yarn packages are eventually formed.

The stud 22 is fixed in such position in the wheel 32 fast with the cam 21 that when the treadle 24 is depressed to disengage the clutch 28 and so to allow the cam 21 to be turned in the direction indicated by the arrow 41 by the weight of the ring rail 10 causing the bowl 35 to bear upon the are 43, 44 of the cam 21 between the part 42 of largest radius and the part. 44 of smallest radius the striking part 22 comes against the pro jection 25 while the cam 21 has still to present the part 44 of least radius to the bowl 35. By this means when the clutch 28 is again allowed to pass into engagement by release of the treadle 24 the cam 21 being again turned by the worm 34 and worm wheel 33 will first lower and then raise the ring rail 10., V

In the use of the mechanism illustrated in the accompanying drawings when the windthe bottoms of the yarn holders so as to be fastened to the spindles 11. Then the com 'pleted or full yarn holders having been re moved from the f spindles 11, empty yarn holders 2 are applied to the spindles 11. Then the handle 40' is turned to raise the sec tor 7 until the catch 15 can be engaged-with the surface 14 of the dog or projection 12.

Then while the catch 15 is engaged with the surface 14, it is ascertained by the observation of the position of the ring rail 10 or the position of the cam 21 or the bowl 35 that the are 42, 43, 44 is presenting to the bowl 35 a part between the part 42 of largest diameter and the part 43 to be against the bowl 35 when the stud 22 comes against the striking part 20. The treadle 24 is then depressed and held so depressed until the cam 21 has brought the striking part 22 against the projection 25 and then the treadle 24 is released so that the clutch 28 may become engaged again. Then the ring spinning machine is started and as the spindles 11 begin to revolve, the cam 21 first lowers and then raises the ring rail 10 so as to wind yarn first in a descending spiral and then in an ascending spiral on the yarn holders 2 below the place at which the ordinary bottoms 6 of the yarn packages will eventually be wound. Then the handle 40 is turned again to raise the sector 7 and the catch 15 is brought into engagement with the surface 13 01": the dog or projection 12 and the formation of the ordinary bottoms 6 of the yarn packages on the yarn holders 2 and the rest of the winding of yarn thereon proceeds in the ordinary way.

When a ring spinning machine is first being put to work the roving to be twisted into yarn may be brought into connection with the spindles or the yarn holders as in the ordinary way of first putting such a machine to work and the commencement of winding of yarn below the place at which the windings to form the bottoms of yarn packages are to be wound on yarn holders may then proceed as in the manner hereinbefore described.

If in any case there is no provision or occasion for yarn to be wound on spindles below the bottoms of yarn holders thereon, yarn may be attached to the yarn holders and be wound thereon in a manner similar to that hereinbefore described below the place at which the ordinary bottoms of the yarn packages are to be formed in a manner similar in other respects to that hereinbefore described.

Similarly yarn may be wound upon yarn holders of forms other than those shown.

This invention may be applied to ring doubling machines and to other machines having yarn guiding means of other forms moved like ring rails in a manner similar to that in which it is applied in ring spinning machines.
