Specification of Iietters Patent. Patented Feb. 17 1914:.

Application filed November 12, 1912. Serial No. 730,966.

To all whom it mag concern Be it known that I, J OHN B. BOLTON, a citizen of the United States, residing at Lawrence, in the county of Essex and State of Massachusetts, have invented certain new and useful Improvements in Winding-Machines, of which the following is a specification.

My invention relates to improvements in winding machines for winding thread or yarn into filling cops or bobbins such as are employed in the shuttles of looms.

My improvement consists particularly in providing in the machine a bunch-builder or device for winding a preliminary section of yarn on the bobbin with a relatively short traverse before the main portion of the bobbin is wound with the maximum traverse;

I the bunch being designed to cooperate with the feeler-devices which control the filling-replenishing mechanism of the 100m to cause the insertion of a fresh bobbin in the shuttle when the one in place runs out. The bunch-building device is designed to automatically control the reciprocating mechanism for the thread-guide, at the beginning of the winding, to cause the guide to lay the thread with a short traverse throughout several courses or layers and to then act to increase the extent of traverse of the guide to its normal length.

The invention is .fully described in the following specification, illustrated by the accompanying drawings, in which Figure 1 is a longitudinal elevation of a winding machine of well-known construction, showing my bunch-building device applied thereto,'the frame of the machine being illustrated in section to reveal the mechanism contained therein; Fig. 2, a plan view of the same; Figs. 3, 1 and 5, enlarged detail viewsof the controlling device for the traverse-mechanism, illustrating the parts in progressive stages of their operation; Fig. 6, a plan view of the same; Fig. 7, a detail view of the ratchet-cam-Wheel which operates the device.

My invention is shown as applied to a machine of the same general type as that described in U. S. Patents Nos. 940,489 and 946,831, granted Nov. 16, 1909, and J an. 18,

1910, respectively, to S. W. Wardwell.

The basic machine consists essentiallyof a rotating winding-spindle B and a reciprocating traverse-bar O, the latter arranged opposite the spindle, and adapted to carry .the thread-guide G, which, besides its movement with the bar, is fed progressively outward thereon to build the cop in superimposed conical layers. The winding-spindle B is mounted in a bearing a in the main frame A of the machine and is rotated from the main driving-shaft E by means of skewgears e, e, The traverse-bar C slides in a quill-shaped bearing a, which has an extension a extending through a bore in the side of the frame A,'and is reciprocated from a rocker-arm F mounted on the continuouslyoscillated shaft D. My traverse-controlling device operates directly in connection with the arm F and is arranged to automatically erse-bar C with the arm to vary the operative length of the latter and regulate the length of traverse of the thread-guide as more fully explained hereinafter.

The traverse-bar C is preferably constructed in two parts C. and C the main portion C sliding in the bearing a, as before ex lainedjand the extension C connected tiereto at its outer end by a pin-andslot coupling 0. The opposite end of the extension C is mounted in a bushing 0 which is swiveled in an outboard bearing j supported on a bracket J extending from the frame A. The coupling 0 allows the inner end of the extension 0 to swing inward from the plane of the axis of the main portion C of the bar, as shown in Fig. 2, while the outer end of the bar swings in the swiveled bushing c. This arrangement is the same as that described in U. S. Patent 940,489, above referred to, and provides that the contact meanscarri'ed on the traversebar, and arranged to feed the thread-guide along the winding-spindle, shall contact adjust the point of connection of the travwiththe first layers of yarn wound -on the bobbin :1: before the base of the cop is ,built up to its maximum diameter. The progression or contact-mechanism is arranged as now briefly described, a more comprehensive description being given in the patent just referred to.

The thread-guide G is preferably supported on a thread-guide holder or arm g,

of bifurcated form, having two legs 9, g" terminatingin bearings 9 g surrounding the bar C Between the'bearingsg g is an internally threaded sleeve or nut h which carries a relatively thin disk H called the contact-wheel. The bar C is formed with screw-threads 0 extending approximately half way around its circumference and a spring h is secured to the guide-holder g with its end bearing on a flange 72, of the nut h. The spring it acts to normally press the nut it into position to engage its threads with the threads 0 on the bar C but the bore of the nut is of suflicient diameter to allow its threads to pass over those on the bar when the nut is pressed in the opposite direction against the force of the spring. It will be seen that while the machine is operating the nut h is engaged with the threads on the bar 0 so that the turnin of the wheel H will feed the thread-guide along the winding-spindle, but by releasing the nut from engagement with the threads on the bar the guide can be slid back to adjust it in position to begin the windingof a new bobbin.

Mounted on the end of the bar 0 is a former K, so termed because it acts to direct the movement of the contact-wheel H away from the winding-spindle during the building of the base or heel of the bobbin and therefore determines the form of the latter. The former K has an arm 70 arranged with its edge 70 at an angle to the axis of the winding-spindle and by adjusting the arm at different angles the taper of the base of the bobbin can be regulated.

Adapted to bear on the edge is of the arm is is a follower-arm 9 extending rearwardly from the thread-guide holder 9. Sliding in a bore at the inner end of the bar C is a spring-pressed plunger 0 ada ted to bear against the inclined face 0 of t e couplingplate 0 and tending to normally hold the bar 0 in position to aline its axis with that of the bar C. The swinging movement of the bar C is limited by its pin a sliding in the slot 0 of the plate 0 and with the follower 9 bearing on the i-nnerend of the formerarm ll"- the end of the bar is held with thepin at the inner end of the slot as shown in Fig. 2. This provides that the contact-wheel H will be maintained in close proximity to the surface of the woodenbobbin or cop-tube m at the beginning of the winding so that its periphery will-contact with the first layers of yarn wound on the latter at the rearward end of each stroke of the thread-guide. The contact of the wheel with the surface of the yarn, during I the rotation of the winding-spindle, acts to turn the wheel to feed the thread-guide outward along the'spindle in the manner now well known tothose versed in the art. As the thread-guide feeds outward along the traverse-bar C the "follower-arm 9 slides along the incline of the arm is and allows the contact-wheel to rec'ede from the axis of the winding-spindle in accordance with the growth in diameter of the winding. As the follower 9 reaches the end of the arm is In this Way the bobbin grows by longitudi- I nal extension, the conical layers forming a substantially cylindrical body terminating in the tapered delivery end or nose.

Referring now to Figs. 1, 3 and 4, the arm F which acts to reciprocatethe traverse-bar C is connected thereto by a link L pivoted at Z on the bar. The opposite end of the link carries a pin or stud Z adapted to slide in a curved slot f formed in the arm F. By sliding the stud Z up and down in the slot f the operative lengthof the arm can be varied to vary the extent of reciprocation imparted to the traverse-bar C and,

rocated with a comparatively short traverse to build the bunch on the bobbin. When a suflicient number of layers of winding have been deposited to complete the bunch, or, more properly speaking, when the required length of yarn has been wound into the bunch, the stud Z is shifted to the upper end of the slot f and the traversebar 0 will then be reciprocated with the maximum length of movement to cause the thread-guide to traverse the yarn to the full or normal extent required to wind the main portion of the bobbin. The means for automatically shiftin the stud Z along the slot 7 consists essential? of a scythe-shaped lever N with devices or operating the lever as now described: The lever N is' ivoted on a screw n screwed into the side of the bearing a which latter is secured in the side of the frame A, as previously explained. Preferably, the lever N is formed of sheet-metal with a downwardly-extending curved arm n terminating in a forked extension a bent back at right-angles and formed with a slot a see Fig. 6, adapted to receive'the link L. The lever N has an ear n adjacent 1ts pivot point to which is attached one end of a s ring M, secured at its opposite end to the side of the frame A by means of a hook m. The s ring M tends to normally hold the lever in its lowermost position with the stud Z at the bottom of theslot f. The lever N is also formed with a downwardly-pro jecting, pointed extension a adapted to be engaged by an abutment 0 on the inside of 'the cam-wheel 0 through which the lever ig operated. The cam-wheel 0, formed with a hub 0', is pivoted on a stud 0 projecting from the side of the bearing a and its periphery is provided with ratchet-teeth 0 The abutment o is formed on or attached to its inner face, as before described, and has a straight edge 0* extending outward from the hub 0' and rounding into the curved edge 0 which follows the periphery of the wheel through a distance of four teeth. These faces cooperate with the pointed extension n on the lever N as hereinafter more fully explained. On the outer face of the wheel 0 is another abutment 0 which also has a curved edge 0 following the periphery of the wheel through a distance of approximately four teeth, the two abutments being arranged substantially ninety degrees apart or at a distance of about one-quarter of the circumference of the wheel. L

Referring to Figs. 5 and 6, an arm P,

,pivoted on the bearing stud 0 of the wheel 0, extends downwardly therefrom and carries a 'pawl p at its lower extremity formed with a hooked end 32' adapted to engage the teeth 0 on the periphery of the wheel 0. A screw 0 screwed into the end of the stud 0 serves to maintain the wheel O and arm P in place on the stud. The pawl p is pivoted on a stud p and a wire spring 9 fastened at q to the arm P is arranged with its end bearing on the back of the pawl to maintain the latter in engagement with the teeth on the wheel 0. Extending through an inclined hole a in the side of the frame A, see Figs. 5 and 6, is a rod R having its end swiveled on a stud p projectin from the arm P, and securedin place on t e stud by the cotter-pin p. Secured to the outer end of the rod R by a pin 8 is a finger-piece S terminating in the flat push-button s. A coiled spring T surrounds the rod R between the side of the frame A and the inner end of the finger-piece S, and tends to force the rod outward from the frame. A pinm, driven down through the rod R," engages the inner side of the frame to limit the movement of the rodunder the action of its spring T. Its movement in the opposite direction is limited by a sleeve .9 on the rod R, the end of which is adapted to come into contact with the outer side of the frame A. By pushing the rod R inward against the action ofithe spring T the arm P can be rocked on its pivot and the pawl 10 moved thereby to turn the wheel 0 in the direction indicated by the arrow 2, Fig. 5. This manually-operated means for turning the wheel 0 is provided in order that the device may be set at the beginning of the winding, as more fully explained hereinafter. The pawl also serves a second purpose of preventing the backward turning of the wheel 0, that is, in an opposite direction to that indicated by the arrow 2, since the rearward movement of the arm P is limited by the pin 1' in the rod R. The automatic turning of the wheel 0 is effected by a pawl U pivoted on a stud u at the end of a rocker-arm V. The end of the pawl U is maintained in engagement with the teeth 0 by a spring u coiled about the stud u, see Fig. 6. The arm V is secured to a shaft W by means of a pin to and the shaft has a continuous oscillating motion during the operation of the machine. Preferably, the shaft W is connected to be rocked from the means which oscillate the rock-shaft D, not here shown, so that the arms F and V move in unison, although this is not essential providing the two arms are operated synchronously.

The operation of the whole machine is as follows: Referring to Figs. 1 and 2, a usual form ofcop-holder, such as the wooden bobbin m here shown, is placed on the winding-spindle B and after the thread-guide G has been adjusted in position the yarn is drawn through it and its end secured to the bobbin. It is then necessary to set the traverse-controlling device to begin the winding with the short traverse to form the bunch on the bobbin. During the winding of the main portion of the bobbin, and at the stopping of the machine upon its completion, the parts of the traverse-controlling mechanism are in the position illustrated in Fig. 5. It will be noted that as here shown the stud Z of the link L is at the upper end of the slot in the arm F and the lever N is in its raised position with the point 42 resting on the abutment o of the wheel 0. To set the device the finger-piece S is pressed by the operator to push the rod R inthe direction indicated by the arrow 3, Fig. 5. This movement of the rod R swings the arm P on its pivot and acts thrbugh the pawl 29 to turn the wheel O in the direction indicated by the arrow 2. One push on the rod R is suflicient to turn the wheel 0 forward through a distance of several teeth and when the rod is released the spring T returns it to its normal position with the pin 1' abutting the "side of the frame A.' With the rod in this position the arm P acts through the pawl 30 to prevent backward turning of the wheel 0, as previously explained. The turning of the wheel 0 forward carries the abutment 0 out from under the point a of the lever N and the spring M then acts to draw the lever downward into the position illustrated in Fig. 3. The link L being engaged by the forked extension 01. of the lever N, is thus carried downward by'the movement of the latter and the stud Z is moved to the lower end of the slot f in thearm F. The machine is now ready to wind the bunch on the bobbin and its operation is started by throwing the clutch-devices into engagement, the parts I of this mechanism being here shown but not described since their operation is well known to those versed in the art. As the machine starts to operate the arm F is rocked back' and forth by the shaft D and the traversebar C is reclprocated with a relatively short extent of traverse while the stud Z is being held at the bottom of the slot f. During the oscillation of the arm F the arm V is also rocked from the shaft W which is preferably connected to the same cam or other similar means, as previously described. The rocking of the arm V acts through the pawl U to turn the wheel 0 forward one or more teeth at each oscillation as may be desired. If a comparatively large amount of yarn is to be wound into the bobbin the movement of the arm V is regulated to advance the wheel a single tooth ata time, but if a lesser amount is desired the movement of the arm can be increased to advance the wheel several teeth at each oscillation, it being understood that the turning of the wheel regulates the time of action of the traverseshifting mechanism as later explained. The intermittent turning of the wheel 0 carries the abutment 0 around its'axis until, near the completion of one rotation of the wheel,

the edge 0 of the abutment comes into contact with the edge a of the extension n' of the lever N. Now, as the rotation of the wh'eel'O continues the extension a will ride outward on this ed e 0, as illustrated in Fig. 4, until finally its extremity is carried up onto the edge 0 During this action, while the lever N is being raised by the abutment 0 bearing on its extension 41, the end of the lever N acts to raise the link L until the stud Z is carried to the extreme upper end of the'slot f in the lever F. The raising of the lever N is accomplishedduring the last few forward advances of the wheel 0 and while the link L is being moved upward the traverse-bar C will be ,reciprocatedwith a gradually-increasing extent of'traverse until finally the maximum extent is attained. That is to say, the change from the minimum to the maximum traverse does not occur instantly but is progressive, there being several reciprocatiofis ofthe thread-guide with a gradually increasing extent of traverse. Referring now to Fig. 5, as the edge 0 of the abutment 0 comes under the point of the extension a the edge 0 of the abutment 0? on the front. of the wheel 0 is brought under the end of the pawl U, it being understood that this end of the pawl 1s bro enough to lap over the teeth ,0, or, in other words, to overhang the wheel 0 on its outer edge. This action raises the pawl 0 so that its end clears the teeth 0 as shown in Fig. 5, and hence the continued oscilla tion of the arm V wilLcease to have any effect on the wheel 0. That is to say, after the wheel .0 has been turned to this position the end of the pawl U will simply ride on the edge 0" of the abutment 0 and therefore no further rotation of the wheel takes place. This provides that the abutment 0 shall remain under the point of the extension 91. of the lever N so that the latter will be maintained in its raised position with the stud Z at the upper end of the slot f during the rest of the winding. With the stud Z held at the upper end of the arm F the maximum extent of traverse is imparted to the travl-erse-bar C so that the remainder or body portion of the bobbin is wound with full length layers. At the completion of the bobbin the device is set again, as before described, to cause the traverse-mechanism to reciprocate the thread-guide with the minimum extent of traverse to begin the bobbin with the short layers which form the bunch. In the drawings I have shown the camwheel 0 constructed with forty-four teeth and if the pawl U is arranged to advance the wheel one tooth at each oscillation then it will require forty-four oscillations to turn the wheel through one complete rotation. Now, as the arm F oscillates in synchrony with the arm V there would be forty-four reciprocations of the thread-guide during one rotation of the wheel 0. As a matter of fact, however, it does not require quite a complete rotation to bring the abutment 0 under the extensionm of the lever N and, furthermore, the wheel 0 is advanced several teeth in setting the device. That is to say, when the rod R is operated its movement will turn the wheel 0 through a distance of several teeth, this provision being made to insure that the wheel is moved far enough to release the lever N from the abutment 0. It will therefore be seen that if the device is set to advance the wheel 0 one tooth at each oscillation of the thread-guide something less than forty-four layers or courses will be wound before the maximum traverseis attained. This is a liberal provision and for most purposes a much less amount of yarn is required in the bunch. In practice, I have found that from eighteen to twenty reciprocations of the guide will give a sufiicient length of yarn in the bunch and therefore the pawl U is preferably regulated to advancethe wheel 0 two teeth for each oscillation of the traversearm F. J

Various modifications might be made in the form and structure of the parts of my device without departing from the spirit or scope of the invention.
