- the operation of my complete device is as follows:
- the casing F is secured to the, top of the frame D of the winding machine above the bearings for the spindle B and traverse-bar C. This is accomplished by simply tapping a hole in the frame D for the screw f at the proper location as shown in Fig. 1.
- the lug f on the casing F is positioned to abut the edge of the frame D at one end and the end of the adjusting screw 1 engages the front of the frame at the opposite end.
- the screw f is set to bring the casing F into such position that the pin 0 on the traverse-bar C will strike the end is of the member K during the inward movement of the bar C to cause said member to move the slide L backward to the position illustrated in Fig. 6.
- the traverse of the bar C is slightly longer than the distance between the pin 0 and end of the member K as shown in Fig. 1, and hence the last end of the inward reciprocation of the bar will carry the men'iber K and its connected slide L through a relatively slight extent of movement.
- the bobbinreceiver 1 Before starting to wind the bobbin the bobbinreceiver 1) is placed on the winding-spindle B and the yarn 3 is led up from its source of supply andv its end secured to the receiver.
- the controller-arm E isnext swung toward the spindle B into the position illustrated by full lines in Fig. l and the yarn 3 is then led through the opening 6 at the end of the arm and threaded into the groove G of thetraverse-guide G.
- the arm E is so moved manually to swing it into its operative position as shown in Fig. 1, and this acts to set the ratchet-mechanism of the device which operates automatically to release the arm after a predetermined number of traverses of the yarn-guide.
- Figs. 2 and 3 when the arm E is swung from the position illustrated in the latter to that shown in the former it operates on the controlling-mechanism as follows:
- the link J carries the member K to the left and moves the lug out of range of the pin so that there can beno further engagement between the two. This prevents further action of the ratchetdevices and therefore all the'parts remain in their inoperative positions until the completion of the bobbin when they are set again by the operator as previously described.
- the device can be set to bunch-winding and this is accomplished by adjusting the ratchet-mechanism in the following manner:
- the number of teeth an. engaged by the pawl 0 before the wheel N the lever S to enter the gap n determines the number of reciprocations of the traversebar required to effect the releasing of the arm E.
- the device is adjusted with eight teeth intervening between the projection 8 and the gap 01. in the wheel N. Therefore it will require eight wheel N into the position illustrated in Fig. 3 to allow the detent-lever S to release the arm E.
- the relation of the gap n to the projection s can be varied feeler-looms, it is desirable to change the location of the bunch with respect to the butt of the bobbin; that is, to wind it a greater or less distance therefrom. This is accomplished by simply loosening the screw 6 illustrated in Fig. 8 and extending or shortening the length of the arm E so as to vary the position of the slot e in relation to the end of the bobbin.
- my invention provides an extremely simple and compact mechanism for eifecting the bunchwinding in bobbins or co s and one which can be applied to any usua form of winding machine without change in the mechanism thereof. It can be attached to the machine practically without machining operations, merely requiring the tapping of a single hole, and will operate in conjunction ⁇ with almost any form of traverse-mechanism without alteration or adjustment of the ele ments therein. It can be set to give any desired number of turns in the bunch-winding, to vary the yardage therein, and can be adjusted to regulate the position of the bunch on the bobbin.

To all whom, it concern Be it known that 1, WILLIAM MARCROFT, a'
citizen of the United States, residing at My invention relates to improvements in winding machines for winding weft orfilling into cops or bobbins for use in the shut-.-
tles of looms; L
My improvement consists particularly in providing means for automatically controlhug the traverseof the thread or yarn at the beginning of the winding in such manner that a preliminary winding or bunch is first laid on the yarn-receiver or naked bob- .bi before themain or service winding is bui tup with the full traverse. The i'elatively short length-of yarn in the primary winding or bunch j is designed to prevent thebobbin from being entirely exhausted before the feeler-devices of the loomcan operate to replenish the. shuttle}. In automatic feeler-looms the feelen acts to cause a change of filling when the yarn has been Woven off the bobbin down to the. pre liminary winding, the bunch still containing. sufiicienhyarn to last while-the change is being made. Theextra yarn in the bunch insures against loose ends or miss-picks in the cloth should'jthe filling in the main portion; of the bobbin run out while the shuttle is crossing from one sideof the loom to the other and backagain. The principal object offmy-inventio'n is to'provide a device which c'an'be applied to winding machines already in use WlthOllh requiring a change in'the traverse-mechanism thereof. With this object in vlew 'I have devised a mechanism whichis adapted to control the laying ofthe yarn at the beginning of the winding independently of the operation oftheiatraverse-gulde.

Referring first to Flg. 1 my invention is here shown as applied to a machine of the same general type as that described inU. S. Patents No. 940,489 and No. 946,831, granted Nov. 16, 1909 and Jan. 18, 1910 respectively to- S. W. Wardwell. It will be obvious, however, that my new device might be adapted to any other-style of machine employinga rotating spindle and reciprocating ide or to machines in which the spindle is reciprocated instead of" the guide to effect the traverse of the yarn., As here illustrated the basic machine consists essentially of a feed the guide along the bar.
rotating winding-spindle B and a reciprocating traverse-bar G, the latter arranged opposite the spindle and adaptedto carrynot here shown or described. A portionof the spindle B overhangs the front of the frame and is adapted to receive the yarnholder or wooden-bobbin b. In some cases a paper tubeis used on the spindle B in place of the wooden bobbin 6 here shown, or
any other form of yarn-receiver might be employed. i
The traverse-bar G is adaptedto reciprocate in bearings in the frameD and is actuated from a rocker-arm or other suitable mechanism not here shown or described. The bar C is preferably constructed in two parts 0' and C which are connected at their adjacent ends by a pin-and-slot arrangement shown at 0. The outer end of. the extension C is mounted in a swiveled,foutboard'bean.

The swiveled arrangement of. the bar C allows the wheel to be pressed intoward the winding-spindle B to adapt it to engage the first layers of yarn wound on the bare bobbin and these elements operate in connection with a former-arm g shown and describedmore particularly in Patent No.-
946,831 to S. W. Wardwell, before mentioned.
My new device is practically independent of the above described mechanism, but is arranged in relation thereto as now explained: Briefly it consists of a controller-arm E having its outer end formed with a curved opening'e to receive the yarny and adapted to be maintained in the position-illustrated by full lines in Fig. 1 at the commencement of the winding to hold the yarn from being traversed on the bobbin by the guide 'G. After the bunch-winding is' completed the arm E is automatically thrown into the position illustrated by the dotted lines in Fig,
Mounted on the bar C between The casing F consists simply of a flat.
plate f formed with two 1 pturned ends If, f' The plate f is secured tot e top ofthe rame D by a screw f extending through a slot i A lug '7 extending downwardly from the plate at one end thereof abuts the front edge of t e frame D and with an adjusting screw f at the opposite end serves to locate the plate'with respect to the traverse-mechanism of the machine, see Figs. 1 and 5. The screw f extends through ,a' lug f with its endiadapted to contact with the front of the frame D andhas a check nut f adapted to lock it from turning. By loosening the screw f and nut f and turning the screw f the plate can be adjusted outward or. in-' .ward on the frame D to a slight extent. 'The object ofthis adjustment is to regulate the position of theoperatingelement of the ='-ratchet-mechanism for'the device which is moved through contact with a pin a? on the,
traverse-bar C as hereinafter more fully expla'ined.

Referring now to Figs. 6 and.8, the slide L carries a pawl 0 adapted to engagefthe .40
" wheel M operates in conjunction with a second, smaller ratchet-wheel N, arranged above it, to regulatethe release of the arm Both ratchets M and N are mounted on' a studP and are connected to rotate to-' gether as now described: The stud P has a- 7 flat head-72 riveted against the plate 7 of the teeth of a ratchet-wheel M. The ratchet casing F, see Fig. 7. The wheels M and N are both fitted to rotate on the main pori tion 7) of the stud P and are'held in place by a flanged sleeve Q. The sleeve Q is, set;
down against the shoulder p of the stud P by means of the nut 79 screwed on to the end of the latter and its lower edge overlaps the face of the wheel N., A wire spring R'is' coiled around the sleeve Q with one end 7% -engaginga hole 11. in the wheel N and-the flange of the sleeve.
opposite end 1" sprung into a hole q in the spring R is normally to rotate the wheel N Fig. 6. The wheel l\[ is connected with the wheel N by -mea-ns of .a finger m formed on its pe'ripherv and bent up and. around, as
Shown in Fig. 7, to engage the teeth 71. of
,of the arm E.
Referring to Figs. 5 and 6,the pawl O is mounted on a pin or stud 0 adapted to turn 'in a bearing in the slide L. The pawl O is formed with a projection 0 adapted to hook The tendency of the the wheel It will be observed that the wheel M has only a little more than half its perimeter formed'with teeth m, and it is also to be noted that the wheel N is constructed with a break in its peri hery taking the form of a vi-shaped cam-surface or gap a. By removing the two wheels M and N from the stud P the finger m can be set to engage different teeth on the wheel Nto adjust the position of the gap n with respect to the last tooth m on the. wheel M for a purpose later explained.
Pivoted on a stud s screwed into the plate 7' is a simitar-shaped lever S having an elbowportion s,see Figs. 1 and 4, terminating-in a pointed projection 8 adapted to engage the teethn of the wheel N as shown most clearly in Fig. v6. The opposite end of the lever S is formed with an arcuate edge-portion .9 provided with a detent-' shoulder s at the inner end thereof. The curved edge 8 is adapted to receive the correspondingly-shaped end e of the arm E. A relatively long, flat spring T is secured 'to the plate 1 at one end by ascrew t and has its opposite end bearing against the lever S to maintain the extremity of the latter bearing againstthe periphery of the wheel N. Adjacent the opposite end of the lever Referring to Fig. 1, the pin' 0 forms a part of the fastening means for the former before referred to, which-is secured S is a caliper-like-member U pivoted on a stud u. The member U has its two divergent legs formed with rounded extremities u, n one of which u bears against the rear edge of the lever S, while the other 16- is adapted to be engaged by the rear end into the teeth m of the ratchet M and is beveled off on opposite sides to provide a V-shaped point 0 at its end. The point 0 is adapted to enter a slot or-opening f formed in the guideway f of the plate f to cause the pawl to be withdrawn from ten gagementwith the ratchet teeth m. A wire spring V is coiled around a screw v fastened .in the plate f with one of its ends -v" held against the upturned port-ion f of the casing The opposite free end '0 of the spring V is arranged to bear against the rearend of the pawl O and normally tends tos ving the latter to carry its pro3ection 0' into engagement with the teeth m. of the ratchet M.. The rear edge of the pawl O is slotted at 0 to provide a recess for the wire of the spring V and preferably the cor ner o is rounded off to allow the end '0 of the spring to slide freely across it. The
spring V besides acting to operate the pawl 0 also serves to move the slide L forward during the operation of the mechanism as later explained. Referring to Figs' 2 and 3, these illustrate the slide L in its forward position, and it will be observed that the pointed end 0 of the pawl is engaged by the slot f to hold the pawl away from the ratchet M. As the slide L is pressed backward in the direction indicated by the arrow 2, Fig. '2, the pointed end of the pawl is released from the slot f and the spring V will then act automatically to carry its projection 4 into engagement with the teeth m, see Fig. 6. The end '0 of the spring V also serves as a stop by engaging the guideway f to limit the backward movement of the slide L; the forward movement of the slide being limited by the engagement of the end of the pawl O with the guideway f.
Referring to Fig. 8, I have here illustrated the arm E as adapted for adjustment to vary its length and thereby alter the position of the yarn-receiving slot 6 in relation to the buttof the bobbin 7) when the arm is in its operative position. As here shown the arm E consists of two sections E and E with the extension E arranged to slide onthe main portion E. A slot 6 in the extension E is adapted to receive a screw 6 screwed into the section E, by which the parts are secured together, and a pin 6* also fitted to the slot acts to maintain the parts in alinement.
Referring to Figs. 4 and 5, the mechanism of the device is protected from dust and lint by a cover W preferably formed of sheet-metal and bent to surround the sides and ends of the casing F. The two sides 112,10 of the cover are formed with indented portions 10 adapted to be sprung into slots f on the front and rear edges of the upturned ends f, f, and openings 10 w are left in the front and back for the slide L and member K which project be-' yond the edges of the plate 1. A swelledoutdome 10* covers the upwardly-projecting stud P and nut 7) to give a neat and finished appearance to the cover.
The operation of my complete device is as follows: The casing F is secured to the, top of the frame D of the winding machine above the bearings for the spindle B and traverse-bar C. This is accomplished by simply tapping a hole in the frame D for the screw f at the proper location as shown in Fig. 1. The lug f on the casing F is positioned to abut the edge of the frame D at one end and the end of the adjusting screw 1 engages the front of the frame at the opposite end. The screw f is set to bring the casing F into such position that the pin 0 on the traverse-bar C will strike the end is of the member K during the inward movement of the bar C to cause said member to move the slide L backward to the position illustrated in Fig. 6. In other words, the traverse of the bar C is slightly longer than the distance between the pin 0 and end of the member K as shown in Fig. 1, and hence the last end of the inward reciprocation of the bar will carry the men'iber K and its connected slide L through a relatively slight extent of movement. Before starting to wind the bobbin the bobbinreceiver 1) is placed on the winding-spindle B and the yarn 3 is led up from its source of supply andv its end secured to the receiver. The controller-arm E isnext swung toward the spindle B into the position illustrated by full lines in Fig. l and the yarn 3 is then led through the opening 6 at the end of the arm and threaded into the groove G of thetraverse-guide G. .The arm E is so moved manually to swing it into its operative position as shown in Fig. 1, and this acts to set the ratchet-mechanism of the device which operates automatically to release the arm after a predetermined number of traverses of the yarn-guide. Referring, to Figs. 2 and 3, when the arm E is swung from the position illustrated in the latter to that shown in the former it operates on the controlling-mechanism as follows: The
inner curved end ve of the arm E first slides off from the end of the lever S and striking the end 24 of the member U tilts the latter to cause its opposite end 11. to
rock the lever S against the action of its spring T. This tilting action of the member U brings the end of the lever S forward beyond the end of the arm E and when the latter is released by the operator the parts will assume the position illustrated in Fig. 10%
2. The lever S then acts as a detent for the arm E to prevent the latter from being moved under influence of the coiled spring I, see also Fig. 4. In the meantime the opposite end 8 of the lever S will have been 1 5.
raised free of the teeth on the ratchet N and this allows the spring R to rotate the ratchet in the direction indicated by the arrow .2, Figs. 2, 3 and 6. The ratchet M being connected to the ratchet N through the fingei-"no m, the two wheels will rotate together until their turning movement is arrested by the finger m striking against the projection s on the lever S. Coincident with the movement of the arm E the member K which is connected thereto by the link J is carried from the position illustrated in Fig. 3 to that shown in- Fig. 2, and, lying parallel with the slide L, its end is will be in position to be engaged bythe pin 0 on the trav- 123 that the manual operation of the arm' E re- 12:
quires only an instant of time, much less, in fact, than that necessary for its explanation.
When the machine is started the spindle B will be rotated to wind the yarn on the since at the beginning of the winding the" yarn y leads to the bobbin through theop'ening e in the arm E the reciprocation of the guide will have practically no effect to traverse the yarn, but will simply draw it out in the free length 'y", see Fig. 1, as the guide moves away from the arm. It will be noted that the slot e in the arm E is somewhat wider than the thickness of the yarn 3 and therefore the yarn will have a limited amount of play across the slot. This play of the yarn provides against the coils being laid on the bobbin one directly ontop of another and results in giving a very slight width to the bunch-winding I)" as illustrated in Fig. 1. Practically speaking, however, it can be said that the yarn is held from being traversed by the guide G during the bunchwinding. As before explained, it is only necessary to wind a comparatively few coils for the bunch-winding and after this is completed the arm E is released to allow it to swing into its inoperative position as .illustrated by dotted lines in Fig. 1. The release of the arm E is efiectedas follows: Each time the traverse-bar C isreciprocated in the direction indicated by the arrow 2,
Fig. l, to carry the guide G toward the butt" of the bobbin 6, the pin 0 on the bar will strike the end 70 of the member K to move the slide-L backwardagainst the action of the spring V. Referring to Figs. 2 and 6, this movement of the slide L releases the end of the pawl O from the slot 7" and allows its projection .0- to'engage one of the teeth m on the ratchet M. As the slide L continues its rearward movement to the position illustrated in Fig. 6, the pawl Q will turn the wheel M through the space of one tooth. The turning of the wheel M eflects a corresponding rotation of the ratchet N connected therewith and this movement takes place at the end of each stroke of the traverse-bar C. During this intermittent rotation of the ratchets M and N- the projection s at the end of the lever S rides over thehteeth n and by engagement with the latter prevents the two ratchets from rotating backward under the influence of the spring B. As the wheel N is turned by'the pawl O in the direction opposite to that indicated by the lever the arrow 2, the gap n fin its periphery gradually approaches the'projection s on S until it finally reaches the posi tion illustrated'in Fig. 3. At this point the projection 8 will pass on from. the last tooth ni' and thisallows the spring T actin on the 50 edge of the lever S to tilt the latter 1nto the position illustrated in Fig. 3. This move- -ment of'the lever S frees its end from the side of the arm and allows the latter to be swung under influence of its spring I in the direction indicated by the arrow :0.
rice its outer end away from the bobbin Z), see dotted lines in Fig. 1, while its inner end rides on the curved edge .8 of the lever S until it strikes the detent shoulder s 7 As the end of the arm E swings away from the bobbin b the yarn 3 is released fromthe opening 6 and henceforth the movement of the yarn is unrestricted so that the guide'G will traverse it on the bobbin to build up the layers of the service-winding which constiswinging movement of the arm E besides acting to release the yarn y also serves to remove the member K from further contact with the pin 0 As the arm E moves to the position shown in Fig. 3 the link J carries the member K to the left and moves the lug out of range of the pin so that there can beno further engagement between the two. This prevents further action of the ratchetdevices and therefore all the'parts remain in their inoperative positions until the completion of the bobbin when they are set again by the operator as previously described.
As before stated thedevicecan be set to bunch-winding and this is accomplished by adjusting the ratchet-mechanism in the following manner: The number of teeth an. engaged by the pawl 0 before the wheel N the lever S to enter the gap n determines the number of reciprocations of the traversebar required to effect the releasing of the arm E. As illustrated in Fig. 6, the device is adjusted with eight teeth intervening between the projection 8 and the gap 01. in the wheel N. Therefore it will require eight wheel N into the position illustrated in Fig. 3 to allow the detent-lever S to release the arm E. This means thateight reciprocations of the traverse-bar C take place while theyarn y is held from being traversed by bunch-winding I) thus formed depends upon the ratio of speed between the windingspindle and traverse-bar. That is to say, the winding-spindle is generally driven at such a rate of speed that it makesse'veral rotations/to one complete reciprocation of the yarn guide, the mechanism of the machine usually being adjustable to vary this ratio. Now, if the machine isset to give for each reciprocation of the yarn-guide, then there will be ten turns or coils. of yarn of the wheel N throughv the space of one tooth. It will thus be seen that if the ratchet-mechanism is set as here illustrated, to release the arm E'after eight teeth have passed under the end of the lever S, then The swinging movement of the arm E carmm the main body of the bobbin. The
regulate the number of turns or coils in the.
reciprocations of the slide L to turn the is turned into position to allow the end of the guide G andthe number of turns inthe say, for example, ten turns of the spindle v wound on the bobbin during the movement during this time the'windingespindle will commences to traverse the yarn to have been rotated eight times ten or eighty turns and therefore there will be eighty ide uild up the main or service-winding of the bobbln. By removing the wheels M and N from the stud P and changing the position of coils wound into the bunch before the a the finger m on the teeth a, the relation of the gap n to the projection s can be varied feeler-looms, it is desirable to change the location of the bunch with respect to the butt of the bobbin; that is, to wind it a greater or less distance therefrom. This is accomplished by simply loosening the screw 6 illustrated in Fig. 8 and extending or shortening the length of the arm E so as to vary the position of the slot e in relation to the end of the bobbin.
It will be seen from the above that my invention provides an extremely simple and compact mechanism for eifecting the bunchwinding in bobbins or co s and one which can be applied to any usua form of winding machine without change in the mechanism thereof. It can be attached to the machine practically without machining operations, merely requiring the tapping of a single hole, and will operate in conjunction \with almost any form of traverse-mechanism without alteration or adjustment of the ele ments therein. It can be set to give any desired number of turns in the bunch-winding, to vary the yardage therein, and can be adjusted to regulate the position of the bunch on the bobbin.
