Specification of Letters Patent. i

Fatented Feb.. d, mit.

Tow'aZZ whom t may concern Be it known that we, FRANK AsnwomH Hour, a subject of the King of the United Kingdom of Great Britain and Ireland, and resident of Noon Sun House, Whitworth Road, Rochdale. in the county of Lancaster, England, and Gnrnnnon limsi-mw, a subject of the King of the United Kingdom of Great Britain and Ireland, and resident of G2 Market street, I'Vhitworth, in the county of Lancaster, England, have invented new and useful Improvements in lVindingellIac hines, of which the following is a specification.

'.Ihis invention relates to winding machines of any kind in which a roll kept revolif'ing isemployed to revolve a winding` holder by friction against such holder vor a conical or cylindrical spool placed upon it or 'yarn or thread wound thereon and provision is made for the holder or spool or yarn or thread wound thereon to be withdrawn as there may be occasion, by hand o1' automatically, out of Contact with the roll as for instance when a yarn or thread being wound into a package of any kind such for example as a cheese or cop or the likeV breaks or comes to an end and the broken end or termination has to be found and pieced orthe package attains the size fresh spool is to be applied to the spindle and to have yarn or thread brought to it.

This invention consists in a simple and efficient device insuring that, once removed :from contact with the roll by hand or by the operation of stop mechanism, a holder or spool or completed yarn package shall be securely held against return toward or against the roll under the influence of vibration or other accidentalv cause and until some person performs the proper movements for permitting the return of the holder or spool or yarn thereon toward or against the roll, the object of the invention being to guard completely against continued rollingV of yarn or thread upon the roll and chaling or polishing or other damage to the yarn or thread thereby, damage to the holder or roll or both by the holder falling against the roll and hindrance to the finding and piecing of a broken yarn or thread or the removal of a completed package or the application of an empty spool to the holder and the attachment of yarn or thread to such spool or other preparation for the winding of a fresh package.

Othenparts of theinvention are pointed out hereinafter and in the claims following.

In the accompanying drawings in which the same letters and numerals indicate corresponding parts in all the figures, illustrative embodiments of this invention are shown.

In the drawings, Figure l is a front eleyation of part of a winding machine, showing one winding head, Fig. Q is a plan of part of a. winding machine showing parts of two winding heads and one cam serving for working the traversing thread guides of both heads. Fig. 3 is a side elevation partly in vertical section through part of a winding machine and shows one winding head in side elevation. Some of the parts shown in Figs. l, 9. and 3 are shown in only one or two of such figures and omitted from the others or other so that other parts may be shown more clearly. Fig. 4 is a side elevation partly in vertical section showing on a larger scale a pawl shown in Fig. 3 and parts carrying and used with it. Figs. 5 and 6 are respectively a front and side elevation drawn on a larger scale than Figs. 1, 2 and 3 and showing a traversing thread guide. Figs. 7 and 8 are respectively a side view and end view of a die used with a traversing guide.

In the drawings many of the parts shown are of well known construction being very similar to parts shown in the drawings of United States Letters Patent No. 952,015, dated March th 1910 granted to John Olipliant McKean and will be described herein in so far as is convenient to facilitate the description of the parts provided according to this invention but it is to be understood that the parts provided according to this invention are applicable to winding machines of other kinds in which they may be desirable.

In the drawings a is a holder of ordinary construction to receive a conical tube or shell 7) on which a package of yarn or thread may be wound. c is a driving roll mounted fast upon a. shaft (Z extending lengthwise of the machine and revolved in brackets d1 by any suitable means. c1 is a collar loose upon the roll to obviate undue friction upon the smaller end of a conical package being wound. e is a cam mounted fast upon a shaft f extending lengthwise of the machine SMS arrow A over the pawl s and revolved by any suitable means shown as provided with three cam tracks g 7L 72, formed as grooves 1n a way usual to work two thread guides c' one at each side of the use in moving the holder c from or con- Y r toward or for holding the holder c away from the driving roll c. As in machines already known the rod Zis made to pass through a, slot n in an arm o mounted on the same pivots p as the lever frame or apron g of the stop motion and furnished with lugs 7' embracing that lever frame or apron g at one side but for the purpose of this invention the slot 'n is formed sopas to allow an upward movement of the rod Z limited as will be hereinafter described. Further for the purpose of this invention a pawl s to engage the rack m of the rod Z and when engaged with it to raise the rod Z against the upper end of the slot n is pivoted in the arm o. In the case illustrated the pawl s Iis pivoted to the arm o by means of the pin Z. The arm is formed so as to provide below the slot n a surface u against which the pawl s may rest in its ordinary position with the rack m of the rod Z resting on it so that the rod Z may be pulled or pushed in the direction indicated by the and the rod Z if raised clear of the pawl s may be pulled forward or pushed backward through the slot n to raise or lower the holder c. The slot n is made of such height that so long as`the rack m of the rod Z is in the slot n and over the pawl s, the pawl s can not be turned past the rack 'm in a clockwise direction as viewed in Figs. 3 and 4 and a slight movement of the pawl s about its pivot t in such clockwise directionwhile in engagement with the rack m will press the rod Z against the upper end of the slot n. A projection (Z2 indicated by dotted lines in the adjacent bracket Z1 forms a stop against which the inclined part of the rod Z may arrive in order that the forward movement of the rod Z and the lifting of the holder a may be limited.

' u is an arm mounted on 'a shaft w made to oscillate in the well-known manner to move the apron or lever frame g in order to raise the holder a.

For simplicity description will be given of the means for supporting and guiding one trolling its return Y j ustable stop 3 thread guide though any number of similar means may be provided in accordance with the number of winding heads in a machine. 1 In the construction illustrated' in the drawings, guide bars li/'tosupport and guide movement are mounted on a frame .a withV arms lV to embrace the studs p on which the lever frame or apron y of the stop motion and the arm 0 are pivoted and with an arm 2 extending downward to carry an ada spring iattached at its other end to a bracket 5 secured bythe bolt G and the nut thereon to a rail j7 forming part of the framework of the machine. The VframesJ is movable about the studs y) independently of the lever frameor apron g and ordinarily the spring l which is in tension holdsfthe adjustable stop 3 which is shown as a setscrew against t-he rail 7 in orderto determine the position of the frame .e and the path of the thread guide z' but leaves theiframe .a

free to be moved about the studs yi'in the direction indicated by the arrow B when Vthe thread guide c' is to'be disconnected from the cam e. The guide bara1 is shown as of rectangular transverse section and adapted to be secured at each end to the frame e by screws 8 which also serve to hold in grooves in the frame socket plates 9 with conical sockets 10 in which the guide bar g/ which is in the form of a cylindrical rod having conical ends to be inserted in the sockets 10, is mounted. rlhe frame e and socket plates 9 are so formed that the guide bars g/ are the thread guide z' in its traversing and to receive connection of parallel to one another and to the axis of the driving roll c. The thread guide which is provided in the usual way withja notch l1 for guiding yarn is provided'with a tubular part l2 yto surround and to'be slid upon the guide bar 'y and with a forked partrl to embrace and to be slid upon the guide bar an and the thread guide z' is fitted to the guide bars m y. so as to be guided thereon with suiiicient accuracy but also to be movable along them with suflicient freedom. The thread .guide z' is provided with two sockets 14, in one or other of which a die 16 provided with a cylindrical shank 17 to fit the sockets toward each end to be engaged with a cam track of the cam e may be pivoted. The shank 17 of the die 16is inserted in the socket 14 when it is to be engaged with the central cam track g of the cam e for a cylindrical package to be wound and in the socket 15 when it is to be engaged in the adjacent right hand track z, of the cam e Vfor a conical package to be wound. The sockets 14, 15 are formed in such positions relatively to the guide notch 11 that when the die 16 is in the socket 14 and engaged with the adjacent right hand cam track 71, for the winding of a conical package the guide notch l1 shall be 14., 15 and a shoe 18 tapering 'Y traveised to and fro in a path in proper po sition relatively to the roll c and holder a or a conical package thereon and that when the die 16 is in the socket 15 and engaged with the cain track g for the winding of a cylindrical package the guide notch 11 shall be traversed to and fro in a path still in proper position relatively to the roll c and the holder 19 or cylindrical package upon it.

As the holder a is raised byyarn or thread being wound around it in the ordinary way the rod Z will be pushed forward over the pawl s tooth by tooth in the direction indicated by the arrow A, the rack m always resting in engagement with the pawl s unless disengaged by some person raising the handle Zhen the stop mechanism ot the machine is actuated to stop winding either through a package attaining the diameter desired or h v a thread breaking or coming to an end the lever 'trame or apron q being turned by the arm 0 about its pivot j) in the direction indicated by the ari'ow B will cause the pawl s to engage the rack m and to be turned about its pivot Z by suoli rack m and made to press the rod Z against the top of the slot a whereupon the continued movement of the lever frame or apron q will pull forward the rod Z in the direction indicated by the arrow A and raise the holder (t. So long as the weightof the holder a is borne by the pawl s the rod Z will hold the pawl s turned so far as it can be in the clockwise direction and will be held thereby against the top of the slot a so that the escape of the rack lm, and the pawl s from one another under the influence of vibration of the. machine is guarded against and the holder a being once raised by the action of the stop motion can not be lowered again without the attention of some person for the purpose oit' lowering` it. lt the action of the stop motion raising the holder c be brought about by the breakage or ending o a thread being wound the restoration of the lever frame or apron q to its ordinary position in the known way will lower the holder o for winding to proceed without it being necessary for the rack m of the rod Z to be disengaged from the pawl s. In order to lower the holder a after it has been raised by the action of the stop mechanism brought about by a. package attaining the diameter desired the rod Z inust be disengaged from the pawl. s and the disengagement may be effected by the rod Z being pulled forward by means of the handle Z2 so that the rack m is ma de to release the pawl s1 which then falling back against the surface u will allow the rod Z to be pushed or allowed to move backward to lower the holder a provided that the rod Z is raised so that the teeth of the rack m are held clear of the pawl s. Accidental disen gagement of the rack fm, from the pawl s is practically impossible and so accidental descent of the holder a is guarded against effectually. The holder a may be raised and lowered at any time in the course of the winding of a package by a person moving the handle 7c it the rack m be raised and kept clear of the pawl s and the rod Z has not been moved into the position then occupied by it through the action of the stop inechanism.

The operation, use and function ot the or cylindrical packages are to be wound will also work similarly to the like parts of maw chinos of the usual construction and arrangement. `Whcn change is to be made Jfrom or to the winding oit a cylindrical package to or from the winding ot' a conical package the changes requisite of either of the holders a and 19 for the other and the tubes or the like on which yarn is to be wound are made in the ordinary way and the frame .a is moved about the pivots 7? in the direction indicated by the arrow B so that the thread guide is withdrawn so far from the cam c that the die 1G can be disengaged from the cani track g or ZL in which it may be at the time and when the l@ thread guide 'Z being pushed along the bars fc 1 1/ to a convenient position the die 16 is moved from the one socket 14 or 15 to the other and then the die 16 is brought opposite to the other cam track h or g and is brought into engagement therewith by the.

'frame being allowed to be moved back by the spring i and then winding may proceed. The change of the die 1G from one of the sockets 1st, 15 to the other and from the central cam track f/ to the adjacent right hand cam track ZL or the reverse change is thus accomplished without any other part than the die 16 being dismounted from the machine and the frame e being simply moved from and allowed to be moved by the spring 4 back to the position determined by the adjustable stop 3 the guide bars :c lQ/ are always brought back automatically into proper position `for winding to proceed. ln

the constructions hitherto provided the change from or to the winding of cylindrical packages to or from the winding of conical packages has been effected by the change Y of thread guides and has involved the dismouiiting of one or more of the guide bars or other parts on or in which the thread guides are mounted for use and in the dismounting of such parts there has been involved the practical impossibility of puti V"through the said space ting them back accurately into their previous positions. The die 16 having a cylindrical shank and the sockets 14:, l5 to receive it being cylindrical the removal of the `die 16 from one of the sockets 1li, l5 to the other and its restoration to the socket in which it may first have been placed for use, involves no possibility of derangement of adjustments.

We would have it clearly understood that changes may be made within the scope of the invention as indicated in the claims.

What we do claim as our invention and desire to secure by Letters Patent is l. In a winding machine, a driving roll, a helder' whereon material may be wound adapted to cooperate with the driving roll so that winding is effected by friction, means for supporting such'holder and enabling it to be moved toward and away from the driving roll, a link for moving such holder connccted to said means and furnished with a handle, Va stop motion comprising a part with a space through which the said link is passed allowing limited movement of such link in the direction of the length of the siace an engaofinv device Jivoted in such` 7 2D D part to iorm a rest for and to engage the link and movable thereby to bring such link against one end ol' the"said space and allowing the link when disengaged from the engaging means to be pushed or pulled whereby the said holder when moved away from the driving roll by the stop mechanism is prevented irom being accidentally moved again toward it, substantially as hereinbefore described.

2. In a winding machine, a d riving roll., a holder whereon material may be wound adapted to coperate with the driving roll y so that winding is effected by friction, means for supporting such holder and enabling it to be moved toward andaway from the driving roll, a rod for movingrsuch holder connected to the said means and furnished with a handle and rack, a stop mechanism said space, whereby the said holder whenV moved away Vfrom the driving roll by the stop mechanism is prevented from being accidentally moved again toward it, tially as hereinbefore described.

3. In a winding machine a driving roll, a

holder whereon material may be wound adapted to coperate with. the driving roll so that winding is eilected by friction, means for supporting such holder andV enabling it to be moved toward and away from the driving roll, a rod for moving such holder connected to the said means and furnishes with a handle and rack, a stop mechanism coinprising an arm with a slot through which the said rod is passed allowing limited movement of such rod in the direction of the length of the slot, a pawl mounted in such armto form a rest for and to engage the rack and movable thereby Vto bring such rod against one end of the said slot and allowing the said rod when disengaged from the pawi to be pushed or pulled through the said slot whereby the said holder when moved away from the driving' roll by the stop mechanism is prevented from being accidentally substan-V moved again toward it, substantially asV hereinbefore described.
