WINDING-MACHINE.

Specification of Letters Patent.

Patented Feb. 17, 1914.

Application filed July 5, 1912. Serial No. 707,824.

To all whom it may concern Be it known that we,'ARTHUR I. H RVEY and .VVILLIAM MAnonor'r, citizens of the United States, residing at- Providence and .chine to wind several layers of yarn on the bobbin with .a relatively short traverse before the winding of the main port-ion of the bobbin with the maximumtraverse is commenced.

The object of our improvement is to provide a machine having a bunch-building attachment for performing the bunch winding at the beginning of the bobbin, the term bunch being generally used to designate the short section of yarn first wound on the naked bobbin and designed to cooperate with the feeler-dcvices which control the weft or filling-replenishing mechanism of automatic looms.

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 showing our new device applied thereto, the main frame of the machine being illustrated in section to disclose the operating mechanism contained therein; Fig. 2,21- plan view of the same; Fig. 3, a detail view of a portion. of the stopping mechanism of the machine; Figs. 4, 5, 6 and 7, enlarged detail views of the controlling device for the traverse-mechanism, illustrating the parts in progressive stages of their operation; Figs. 8, 9 and 10, detail views of the parts of the controlling device.

()ur 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 Jan. 18,

1919, respectively, to S. W. lVardwell. The basic machine consists essentially of a rotating winding-spindle B and a reciprocatmg traverse-bar C, the latter arranged opposite the spindle, and adapted to carry the thread-guide G, which besides its movement with the bar is fedprogressively outward thereon to build the cop in superimposed conical layers. The winding-sp1ndle 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 skew-gears e, e. The traverse-bar C slides in a quillshaped 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. Our new traverse-controlling device operates directly in connection with the arm F and is arranged to automatically adjust the point of connection of the traverse-bar C with the arm to vary the operative length of the latter and regulate the length of traverse of the thread-guide.

as niore fully explained hereinafter. v

. The traverse-bar C is preferably constructed in two parts C and C the main portion C sliding in the bearing a, as before explained, and the extension C con nected thereto at its outer end by a pin-andslot coupling a. The outer end of the extension C is mounted in a bushing 0 which is swiveled in an outboard bearing 7' supported on a bracket J extending from the frame A. The coupling 0 allows the inner end of the extension C 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 o. This arrangement is the same as that described in U. S. Patent 940,489, above referred to, and provides that the contact means carried on the traverse-bar, and ar ranged to feed the thread-guide along the winding-spindle, shall contact with the first layers of yarn wound on the bobbin a: 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.

l jlit The thread-guide G is preferably supported on a thread-guide holder or arm g, of bifurcated form, having two legs 9, g terminating in bearings 9 g surroundingthe 5 bar C Between the bearings 9 g is an internally threaded sleeve or nuth which carries a relatively thin disk H called the contact-wheel. The bar C is formed with screw-threads 0 extending approximately 10 half way around its circumference and a spring h is secured to the guide-holder g with its end bearing on a flange h of the nut 71.. The spring it acts to normally press the nut it into position to engage its threads with the threads 0 on the bar 0*, but the bore of the nut is of sufficient 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 seenthatwhile the machine is operating the nut h is engaged with the threads on the bar C so that the turning 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 he slid back to adjust it in position to begin the winding of a new bobbin.

Mounted on the end of the bar C is a former K, so termed because itacts 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 is arranged with its edge is at an angle to the axis of the winding-spindle and by adjusting the armat different angles the taper of the base of the bobbin can be regulated.

40 Adapted to bear on the edge 70' of the arm A: is a follower-arm g 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 adapted to bear against the inclined face 0 of the couplingplate a and tending to normally hold the bar C in position to aline its axis with that of the bar C. The swinging movement of the bar C is limited by its pin 0 sliding in the slot 0 of the plate a and with the follower 9 bearin on the former-arm k the end of the bar is held with the pin 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 bobbin or cop-tube at the beginning of the windin so that its periphery will contact with t e 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 the rotation of the windingspindle, acts to turn the wheel to feed the thread-guide outward along the spindle in the manner now well known to those versed oewe? in the art. As the thread-guide feeds outward along the traverse-bar C the followerarm g slides along the incline of the arm is and allows the contact-wheel to recede 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 I: the base of the bobbin or cop attains its maximum diameter and. the bar 0 assumes a position in alinement with the bar C. Henceforth the two sections C and C of the traverse-bar C are reciprocated in the same plane, as one continuous bar, and the contact-wheel H engages the bobbin at the rearward end of each reciprocation at a point on the base of its forward conical end. In this way the bobbin grows by longitudinal extension, the conical layers forming a substantially cylindrical body terminating in the tapered delivery end or nose.

The stopping-mechanism of the machine for arresting the rotation of the windingspindle and the reciprocation of the threadguide consists essentially of a rockable bridge-member L which is pivoted on suitable hearings in the frame A and extends across and above the shafts E and D. The inner end of the member L is mounted on a rod Z secured in the inner side of the frame A and the outer end is formed with a socket Z which receives the end of an extension L secured in place by the screw Z The extension L reaches through a bearing in the outer side of the frame A, and secured in a bore at its end is a rod M held by the setscrew m. The opposite end of the rod M passes through a bearing m in the bracket J and is bent down to form a handle M.

The skewgear e which is driven from the gear e is'mounted free to turn on the winding-spindle B and is connected rotatively therewith by means of a clutch-member N, see Figs. 1 and 2. The clutch-member N is keyed rotatively with the spindle, but is free to slide thereon to carry its tapered face a into and out of engagement with the corresponding face 6 of the gear 6. A coiled spring n bearing against a collar n tends to normally maintain the clutch-member N in engagement with the gear 6 sothat the winding-spindle is driven therefrom; and the clutch-member is re; leased from the gear a to arrest the rotation ,of the spindle by means of a'lei'er Z The lever Z is preferably formed as a part of the bridge-member L and extends upwardly therefrom with its end adapted to engage the beveled face of an annular flange a formed on. the clutch-member N.

Referring to Figs. 2 and 3, the rockerarm F which reciprocates the traverse-bar C is formed with a double hub f mounted free on the shaft D and connected therewith by a clutch-bloek O secured on the shaft by a screw 0. Preferably, the hub f is provided 1 block.

with a key or spline 1'' adapted to engage a corresponding slot 0 in the face of the block 0 and a coiled spring 0 bearing againstv acollar 0 tends to normally hold the hub f in engagement with the clutch Thehub .f is disengaged from the block 0 by means of the bridge-member L which is formed with an overhanging portion Z having aface Z adapted to engage with a tapered projection f on theend of the hub f to slide the hubagainst the action of the spring 0 see Fig. 3. A double-ended spring Z, see Figs. land 2, is secured to the top of the member L with its free ends Z Z reaching down adjacent the sides of the projection f on the hub f of the arm F. The

ends of'the spring Z act to prevent excessive rocking movement of the arm F after its disengagement from the clutch-block O and serve to holdthe arm in such relation to the clutch-block as to insure the spline f" being engaged with the slot 0' upon the release of the hub from the member L.

Referring now to Figs. 4, 5, 6 and 7, the arm F is formed with a curved slot f extending from its upper end to a point adjacent its hub. Connected to the main por-n tion .0 of the traverse-bar C by a pin 0" is a link P. carrying a. stud at its opposite end adapted to engage theslot F. A coiled spring 9 fastened to an extension f on the top of the arm F and secured to the link P at 79' tends to normally maintain the stud p at the upper end of the slot f see Fig. 7. By sliding the stud 72 down in the slot f the operative effect of the arm F maybe varied to shorten the extent of traverse imparted to the traverse-bar C and throughthe latter to the thread-guide G. At the commencement of the winding of a bobbin the stud is held p at the lower end of the slot f and will therefore move through an arcof relatively short radius when the arm F is'oscillated, so that the thread-guide is reciprocated with arelatively short traverse to build the bunch on the bobbin." When the bunch has been builtup to the required diameter, or, more properly speaking, when a sufficient length of yarn has been wound into the, bunch, the stud 12 is'moved to the upper end of the slot f and the traversebar C will then be reciprocated with the mariimum extent of. traverse to wind the full layers whichform the mainportion of the bobbin. The means for automatically controlling the position of the stud 79 in the slot P will now be described.

Pivoted on a screw 0* screwed into the side of the arm F is a ratchet disk or wheel P R having an annular rim or flange r on its smaller diameter than its main portion to adapt it to enter the opening 1 in the flange hen the disk is 'turned to register the opening r with the slot f in the arm- F, as shown in Fig. 4, the pin 29? will pass through the opening 7' and by turning the disk slightly the under side of the flange 1" will engage the in and retain the stud p at the lower en of the slot J, as illustrated in Fig. 5; To release the pin p fromflengagement with the flange?" the disk R" rotated in the direction. indicated'by the'arrow z, Figs. 4, 5, 6 and 7 until the slot- 1' again registers with the slot f in the arm F. This rotation of the disk R takes place during the winding-of the bunch onthe bobbin and is effected by the rocking motion of the arm F through means now described: Secured to the hub f of the arm F by a screw 8 is a flat-spring pawl S formed with a hooked end 8 adapted to engage the teeth r on the ratchet-disk R to prevent movement of the latter in' a direction opposite to that indicated by the arrow 2. Pivoted on a stud t adjacent the end of the link P is a pawl T formed with a hooked end t,

also adapted to engage the teeth 1 on the disk R. The hub ofthe pawl T is formed with a lug or abutment t havinga flat face t see Fig. 10, against. which the end of a spring U-bears. The spring U is preferably formed of flat spring-metal, bent in hairpin shape, and secured in position bya 'pin '0' held in the end of the link P and having aslot 42 through which one end at of the spring passes. The tendency of the spring U is to hold the pawl T in the position illustrated in Fig. 6 to adaptits end to engage the teeth 1 on the disk R, while allowing the awl to rock slightly to ride backward over the teeth. The turning of the ratchet-disk R in the-direction indicated by the arrow .2

is accomplished by the upward and down-' ward movement of the pawl T due'to' the rocking movement of the link P on its pivot p, in relation to the arm F, as the latter is oscillated back and forth by the rocker-- The pin Z- is adapted to engage with a depression or groove f? in the top of the projec- 'tion j when the arm F is rocked into its forward position, see Fig. 7. The engagement of the pin l -with the groove f takes lace only when the arm F is disconnected from the clutch-block O, as shown in Fig. That is to say, during the operation of the machine the bridge-member L is in such position that its overhanging portion Z is raised free of the projection f on the hub f, as shown by dotted lines in Fig. '3, and consequently the in Z is out of range of the. groove f in t e top of the projection. When the bridge-member L is rocked to stop the machine its overhanging portion Z is brought down into engagement with the beveled edge of the projection f, as shown by full lines in Fig. 3 and previously described, and the pin Z is carried into position to engage the groove F. The object of this engagement of the pin Z with the groove f is to hold the arm F at the forward end of its stroke so that the traverse-controlling mechanism may be set in its initial position to start the winding of the bunch as more fully described hereinafter. It is also to be noted that it is not necessary for the arm F to be in its forward position when the portion Z of the member L rocks downward in order to effect this engagement of the pin Z with the groove f Should the movement of the arm F be arrested in any position other than that at the forward end of its stroke the projection f can be swung over under the pin 1 by simply rocking the arm F forward. Such movcment of the arm is effected manually by pulling the traverse-rod G outward through its bearingin the frame A. It will be observed that the forward edge of the projection f 'is rounded 0d at f to adapt the pin Z to ride up onto the top of the projection and the inherent spring tendency of the pin causes it to drop down into the groove f? when the latter comes into alinement with the pin.

The operation of the whole machine is as follows: Referring first to Figs. 1 and 2, we have here shown a wooden bobbin :0 of usual form applied to the winding-spindle B, but other forms of holders for the yarn, such as paper cop-tubes, for instance, might be employed with'equal efi'ect. Figs. 1 and 2 illustrate the machine at the beginning of the winding and we have shown the traverse rocker-arm F at the forward end of its throw. It is obvious, however, that the ma.- chine will not always stop with the arm F in this position, nor is it necessary, because,

before starting the winding the operator must set the bunch-building mechanism and he is instructed to perform the following operations: The first step taken is to pull the traverse-bar C outward in the direction indicated by the arrow 20, see Fig. 1, and if the arm F is in any otherposition than at the forward end of its stroke it will be moved forward until the pin Z engages the groove f in the projection) of the hub f, This engagement of thepin and groove locks the arm F in its forward position, as shown in Fig. 1. The operator now pushes the traverse-bar C backward in the opposite direction and, the 'arm F being held from movement, the stud p on the link P is forced down to the bottom of the slot f During the time the machine is operating to wind with the full traverse of the thread-guide the ratchet-disk R remains in the position illustrated in Fig. 4 with the opening r of the flange r in line with the slot f of the arm F. The pin p on the stud p will therefore pass through the opening rflwhen the stud is pushed down in the slot f and lie under the flange 1". At thisv point the pawl T will engage one of the teeth r on the disk R and hold the link P against the action of the spring 9 in the position illustrated in Fig. 4. The bunch-building mechanism is now set ready to windthe first layers of the bobbin with a short traverse, and the threadguide G is next adjusted. in its rearward position on the traverse-bar C and the yarn 3/ threaded through it with its end secured to the bobbin :1

The operation of the machine is started by turning the handle M which. operates the bridge-member L to release its. lever Z from the clutch-member N, it beingunderstood that the member L is withheld from action by suitable detents not here shown.

As the clutch-member N is released it is carried into engagement with the gear e,

rotation of the gear imparts rotation to the winding-spindle B. Concurrently with the release of the clutch-member N, the projection f is also released from engagement with the member L and the hub f of the arm F slides into position to engage the clutchblock 0, under the influence of the spring 0?. As the slot 0 rocks into alinement with the spline f on the hub {i the two are engaged and in this manner t to the rocker-shaft D and is oscillated thereby. The stud p is now at the bottom of the slot and the rocking movement of-the arm F is transmitted to the traverse bar C through the link P to impart a relatively short traverse to the thread-guide G. The pawl T is now hooked underone of the teeth a on the disk R to hold the end of the link P in its lowermost position, 'as before described, and the first backward movement of the arm F will cause the link to rock slightly in relation to the arm. This causes the'end of the pawl T to be moved upward around the axis of the disk R and hence the disk will be rotated to a slight extent by the so tion of the pawl. Fig. 4 illustrates the arm F at the forward end of its first throw while Fig. 5'shows it at the rearward end and it will be seen that in this latt r position the disk R has been turned thro gh a distance equal to the length of one tooth. This brings the end of the flange 1* .over the pin p on the stud 72 sothat the latter is held at the lower end of the slot f after the pawl T swings away from the teeth 1". The upturned lip r on the flange r is provided to insure that the pin 39 will slide easily under the edge of the flange even if there pin p of the operation of the mechanism. At the next forward stroke of the arm-F the pawl T is again engaged with the next tooth on the disk R and upon the rearward movement of the arm the disk is turned again to carry the rim 1" still farther around on the This action continues until the disk R has been turned through a complete rotation and the opening 1' is again brought into alinement with the .slot f on the arm F. Fig. 6 illustrates the parts in the position they assume just previous to the completion of the rotation of the disk R. The pin 12 is now held just under the rear edge of the flange r and as the arm F moves backward into the position illustrated in Fig. 7 the disk It is turned sufiiciently to bring the opening r in line with the pin 12 and the latter is released. The release of the pinp allows the spring 1 to carry the stud p to the upper end of the slot f and henceforth the arm F will act through the link to impart the full length of throw to the thread-guide. After the release of the pin 72* the pawl T is carried away from the disk R and hencethe latter is not turned farther, but is held by the pawl S with the opening r in the flange r in position to admit the pin p when the mechanism is reset for winding a new bobbin.

Referring now to Fig. 2, it will be seen that while the stud p is at the bottom of the slot f the arm F will act to reciprocate the thread-guide with a traverse of about one half the length of the full traverse illustrated by the layer 'y This causes the yarn to build up in the relatively short layersto form the bunch y and the number of layers in the bunch is determined by the number of oscillations required to turn the disk .B. through a complete rotation. We

have preferred to show our device arran ed with sixteen teeth on the disk R, so t at sixteen traverses of, the thread-guide will take place before the bunch is completed, but it is obvious that a greater (ir less number of teeth might be provided so that more or less yarn would be wound into the bunch. Furthermore, the ratchet might be made with very much' finer 'teeth and means provided to adjust the pawl T to take one ora number of teeth at each movement of the arm F so that the bunch could be'w ound to contain various lengths of yarn as desired. After the bunch is completed on the bobbin the traverse-mechanism acts to reciprocate the thread-guide with the maximum extent of traverse to build the main portion of the bobbin with full length layers as before described; and after a bobbin is completed the parts of the controlling-device are in position to be reset for winding'the bunch on the next bobbin. The resetting of the device is accomplished with two simple movementsof the hand, as before explained, and requiresno special skill or expertness on the part of the operator. Furthermore, the-arrangement is so simple, and the mechanism so positive in action, that the device cannot get out of order and it is practically proof against damage through carelessness.

It is obvious that our new device might be applied to machines of different design from that here shown and described, or 7 adapted for other arrangements of winding mechanism. For instance, the controlling-v device for regulating the extent of the traverse with which the yarn is wound might be arranged to operate in connection with a traverse-mechanism for reciprocating the winding-spindle in respect to the guide instead of reciprocating the uide, itself.

Various modificationsmig t also be made in the form and structure of the parts of our device without departing-from the spirit or scope of the invention.
