Application filed March 13", 1911. Serial No. 614,011.

To all whom it may concern:

Be it known that I, EDWIN SYKES, a subject of King George V of GreatBritain, residing at Huddersfield, in the county of York, England, have invented certain new and useful Improvements in Yarn or Like- Winding Machines, of WhlCh the following is aspecification.

Thls invention has reference to the winding of yarn or the like on tubes, bobbins or similar carriers and comprises n ew or 1mproved means for effecting the wlnding operation, the object of my improvements being to wind the yarn in a solld, uniform and compact mass and at a high velocity. In em from cops or bobbins wound by the said means, the l1abil1t'y of the yarn to slufl ofl" or otherwise become dlsarranged is minimized.

In the accompanying drawings :-+F1gure 1 is a front elevation partly in SCt10Il, 0f one winding head of a winding machine constructed in accordance with, and embodying my improvements; Fig. 2 is a slde elevation looking in the direction of the arrow A, F ig. 1, some parts shown in this figure being omitted from Fig 1; Fig. 3 1s a part plan view taken on the me B, B, Flg.

Fig. 11- is a detail View showing the arm and the cam surface 44.

As my improved winding machine is built up of a number of similar winding heads, I

have only deemed it necessary for the purpose of describing my invention to illus trate and particularly describe one of such heads. It will be understood that 'the machine may comprise any number of heads arranged side by side, and preferably I provide two rows of winding heads in a machine, one row facing to one side of the machine and the other row facing to the o posite side thereof. Further, I preferably diuve the said two rows independently so that one row of heads may be driven at a speed I per end a bearing 5' and at its in the usual way the bobbin 1 row at a speed suitable for a different class of yarns so that two different classes of yarn can be wound at the same time in the ma.- chine.

Referring to the drawings, head comprises iently mounted on a longitudinal rail 2 and having a suitable bearing 3 forthe driving shaft 4 which extends the full length of the machine and is driven by hand, strap, or other means from any suitable source, the system of drive adopted being preferably one that will revolve the shaft 4 at a high rate of speed, the machine and the individual winding heads being so coneach winding structed as to be capable of being driven at the highest possible speed suitable for the yarn to be wound, and at a much higher speed than is now usual in winding frames.

Secured on the casing 1 at the back thereof is a vertical bracket 5 havin at its upl ower end a bearing 5 which said bearings support and guide a vertical spindle 6 adapted to have a rotary and an up and down motion thereon. The spindle 6 for a portion of its length has thereon a screw thread 6' and has fast thereon, toward its lower end, a helical pinion or gear wheel 7 of a suitable length. Also fast on the spindle 6 at its lower end is an arm or extension 8 carrying a small roll or bowl 9 which'rests upon and is adapted to travel over a fixed cam .track 10 as the spindle is rotated and to give a vertical frising and falling motion to the spindle at each revolution, 1n engagement with the cam track by a the roll 9 being maintained coiled spring 11 confined betweenthe upper face of the helical pinion 7 and the underside of the bracket bearing 5 The helical plnion or gear wheel 7 meshes with a helical toothed wheel 12 fast on a sleeve 13mounted on-the longitudinal shaft 4. On said sleeve is also fast abevel wheel 14 with which meshes a bevel pinion 15 fast on a beth or other suitable spindle 16 su in this instance in a lug 1 of the casing, and being ada orted in the iiiterior ted to receive or it may be the tube, upon which the yarn is to be wound.

Fast on the end of the sleeve 13 is a clutch boss 18 adapted to be engaged by a clutch member 19 slidable on androtat-ivel connected to asleeve 20 fast on the shaft suitable for one class of yarns and the other i a suitable casing 1 conveneyelet 30' 4, operation of the clutch member 19 enabling the sleeve 13 to be revolubly connected to the driving shaft to drive the winding head or to be' disconnected therefrom at'will to allow the head to remain stationary, without interfering with or stoppin the remaining winding heads on the mac line. The clutch member 19 is, in the embodiment shown, adapted to be actuated by a pin 21 on a short arm or extension 21 on a spindle 22 journaled in a bearing 23 on a bracket 24 fast to the rail 2. A stop motion, to be hereinafter fully described, is provided to self-actinglyactuate the spindle 22, on breakage or failure of yarn, to cause the clutch member 19 to be moved out of frictional engagement with the clutch boss 18 and the winding head thus stopped.

On the screwed portion 6 of the vertical spindle 6 is loosely mounted a toothed or notched disk or wheel 25 having a downwardly extending hub 25 of which a portion is cut away (see Figs. 4 and 5) toadmit a half circular or segmental nut 26 carried by a clamp 27 provided with a spring 28 acting to normally hold the said nut 26 in engagement with the" thread of the spindle, the engagement of the nut causing the disk 25 to move vertically with the spindle '6 .as'the latter is moved up and down by the action of the cam surface 10 as said spindle revolves, engagement of 'the nut causing it to revolve with the spindle and consequently to revolve the disk 25 whose vertical osition with respect to the spindle therefore remains unchanged.

Loosely mounted on the upwardly extending boss 25 of the disk 25 is an arm 29 which has an opening 29' in the free end thereof forming a fork adapted to embrace and slide up and, down in a vertical guide track 5 in the bracket 5 which prevents oscillatory or rotary movement of said arm. The arm 29 has a side extension 29 in an opening in which is pivotally mounted a wire or finger 30 having a guide hook orat. one end thereof adapted to guide the yarn on to the bobbin and an arm 30 having a downward extension 30 which normally occupies a position adjacent to but clear of the notched periphery of the disk 25. The extension 30 is normally held out of engagement with the ratchet wheel by the tension of the yarn which passes to the ide hook 30' at an angle, as shown in Fig. 2. A ball bearing 25f (Fig. 4) is provided to permit of free movement of the disk 25 when same is rotated.

The. yarn to be wound on the tube or bobbin 17 is unwound from its carrier and caused to pass through a tension device 31 of any Suitable construction and through the hook or eyelet 30' of the pivoted wire and the frictional or finger 30 and is thenwound around the bobbin to secure it thereto, the disk 25 being lowered on the screw 6 to bring said eyelet or hook 30" into proper position to commence winding at the butt end of the bobbin. On the spindle 22 being moved, by the actuating lever 32 fast thereon, to cause the clutch member 19 to be moved into frictional engagement with the clutch boss 18 on the sleeve 13, the spindles 6 and 16 are revolved and through the action of the fixed cam. 10 the spindle 6 is given a rapid up and down movement to give the required chase to the yarn wound on the bobbin 17 the depth of chase being of course determined by the lift of the cam.- As the disk 25 moves down with the spindle 6as the latter descends and the eyelet or hook 30' comes opposite to the full diameter at the bottom of the bobbin, assuming that the latter has the ordinary tapered butt end, the said eyelet or hook is moved outwardly as is indicated by the dotted lines in Fig. 3' and the downward extension 30 and the arm 30 of the pivoted wire or finger 30 is moved inwardly and caused to engage the toothed or notchedperiphery of the disk 25. This causes the rotary movement of the said disk due to the frictional engagement of the nut 26 with the screw 6', to be momentarily retarded and the .screw therefore rotates through the nut and causes the disk to be raised slightly on the screw, the point of commencement of the chase thus being raised gradually as the yarn mass on the bobbin reaches its full diameter at each chase, and the yarn continuing to be wound on in uniform layers one above the other to build up the remainder of the cop to the same diameter.

To automatically stop the parts on the breakage or failure of the yarn I provide the following means. The yarn on passing from the tension device to the eyelet or hook 30 is led under a detector wire or pin 33 extending out laterally from a dagger 34 pivoted loosely at 35 to one arm of a lever 36 pivotally mounted on the bracket 24. The lever 36 has a lateral projection 36 (Figs. 8 and 9) adapted to normally extend into a recess 37 in a disk 37 fast on the spindle 22, a spring 38 acting on the downwardly extending arm of the said lever, to hold the projection in engagement with the disk. If the yarn should break or fail the pivoted dagger 34 is allowed to fall and its front end drops into the path of and is en-. gaged by a spring pin or plunger 18 reciprocated'by the engagement therewith of a swell or enlargement 18 on the clutch boss 18, which causes the said dagger to be forced endwise and'to rock the lever 36 on I its pivot, withdrawing the projection 36 from engagement with the 'notch 37' in the disk 37 and allowing a spring 22' to act to .vide on the bracket 5 a cam surface 3) so located that during the Winding of' partly rotate the spindle 22 and cause the clutch member 19 to be moved out of frictional engagement with the clutch boss 18, thus disconnecting the sleeve 13 from the driving shaft and allowing the parts to come to rest. A rearwardly extending rod 39 projecting from the downwardly extending arm of the lever 36 passes through an eyelet or loop at the lower end of a vertically movable rod 40 having at its upper end a finger orarm 41 adapted to extend into the path of the arm 29 carried by the disk 25. When the cop has been built up to the desired height the finger or arm 41 is engaged by the arm 29 and the rod 40 is raised which, as will be understood, causes the lever 36 to be rocked on its pivot and the disk 37 to be freed, to permit the spindle 22 tobe rocked to stop the motions of the parts. On completion of winding of a cop, the clamp 27 is actuated toremove the nut 26' from engagement with the screw 6? and the disk is slid down the spindle back to its initial or starting position.

In a modified construction of stop motion (Fig. 10) for stopping the winding head on breakage or failure of the yarn or thread, the pivoted dagger 34 carrying the detector wire 33. is pivoted to an arm 42 passing through a spring'plate 43 carried by a suitable fixed part, the spring acting to normally hold the forward end 42 of the arm 42' in engagement with a notch or recess 37 iln a disk 37 fast on the spindle 22 controlling the clutch member 19. On the dagger 34 dropping, through breakage or failure of yarn, into the path of the swell 18 on the clutch boss 18, and being forced endwise thereby, the disk 37 is released and a spring acts to partly rotate the spindle 22 to bring about a stoppage as above described.

\Vhen winding on to paper tubes or tubes Without taper heads or butts, I pro- 44 (Fig.

the lower portion of the cop, a finger 45 pivoted in an extension 29 of the arm 29 carried by the disk 25, is caused to wipe over same and to be moved at each vertical movement of the spindle 6 against the action of a spring-46 to bring its opposite end 45 into engagement with the notched periphery of the disk 25 to intermittently hold same stationary and give the required build to the bottom of the cop. The cam surface: 44 is set at the desired height on' the bracket 5 and on the requisite build having being attained and the full diameter of the cop reached the pivoted finger 3O commences to act and the building up of the remainder of .the copproceedsin the manner previously described.

It will be understood that I do not limit myself to the exact constructions above set forth and that other forms of gearing for driving the spindle 6 may be employed although so far I have found helically toothed wheels to answer very well for the high speeds at which my improved winding heads revolve.

Having thus described myv invention,

what I claim as new and desire to secure by Letters Patent is 1. In a winding machine, the combina tion, with a revoluble bobbin spindle, of a revoluble guide spindle provided with a screwthreaded portion, means for reciprocating the guide spindle longitudinally, a yarn guide, an arm for supporting the yarn guide, a sectional nut operatively connected with the said arm and normally held in frictional driving engagement with the screw threaded portion of the guide spindle, and means for arresting the rotation of the sectional nut periodically without arresting the rotation of the guide spindle, thereby moving the said arm and yarn guide longitudinally of the bobbin spindle.

2. In a winding machine, the combination, with a revoluble bobbin spindle, of

a revoluble guide spindle provided with a screw threaded portion, means for reciprocating the guide spindle longitudinally, a pivoted yarn guide having an extension, an arm for supporting the yarn guide, a screw threaded sleeve encircling the guide spindle and having the said arm mounted on it, a toothed wheel secured on the said sleeve and adapted to be engaged periodically by the extension on the yarn guide to arrest the rotation of the wheel without arresting the rotation of the guide spindle, and a SGCtlOIlfi-l' nut carried by the said sleeve and normally held in frictional driving engagement with the screw threaded portion of the guide spindle.
