20 Claims,

This invention relates to winding machines for winding yarn, thread and similar textile materials into packages, such as cops, bobbins, pirns and the like. More specifically, the invention relates to the 'carmarking or identifying of textile packages as they are produced on the winding machine.

In the present specification and claims the term yarn is employed to indicate all kinds of attenuated material and the term bobbin is used to designate the wound package whatever its form or character.-

It is a common practice in textile mills to identify filling yarn by marking the bobbins with crayon or chalk to indicate different types and counts of the yarn and also to identify the machine or department in which the yarn is processed or handled. The operator of the machine marks the yarn on the bobbin by drawing a piece of chalk or crayon across the surface of the wound bobbin, but this operation has certain disadvantages a it is liable to cause the chalk dust to infiltrate into the mechanism of the machine to interfere with its proper functioning. Moreover, it is impractical to apply chalk or crayon marks to certain types of filling such as worsted r woolen yarn.

The practice of marking bobbin for identification of the yarn is for the purpose of preventing mixed counts or difierent twists of filling from going to the same loom and becoming incorporated in the fabric. In such case the difference in the size or twist of the filling does not become evident until the cloth is woven and therefore often results in spoilage or seconds in the product of th mill. When the bobbins are properly marked the weaver can discover if mixed yarn is furnished to the weave room and place the responsibility in the winding room or other department of the mill where the yarn is processed or handled. In other instances, by applying several distinguishing marks to the yarn on the bobbin its progress from the source can be followed and when poor or imperfect bobbins reach the weave room they can be traced to the machine in which they were wound or to the department in which the yarn was processed. In some mills different types or counts of yarn are wound on different spindles of the same machine and the bobbins may become mixed through carelessness of the operator, as by the dropping of bobbins on the floor or by incomplete emptying of the collecting boxes for one type of yarn before bobbins of another type are placed therein. Most mills handle more than one count of yarn at the same time and as the counts must be kept separate it i an object of the present invention to provide automatically-operated apparatus for earmarking or identifying the bobbins as they are produced in the winding machine by attaching an identification tag or ticket thereto to prevent mixed counts from being wovenvln the loom; and further, to trace the steps in the processing of the yarn in different departments of the mill to correct defects or deficiencies in its manufacture.

Another object of the present invention is to provide an apparatus of the type indicated which is adapted to be applied to existing winding machines as an attachment.

Another object is to provide an apparatus 0 the type indicated which is adapted to feed a tag or ticket from a continuous strip thereof into position to be gripped between the winding yarn strand and bobbin and to sever the ticket from the remainder of the strip.

Another object is to provide an apparatus of the type indicated which is automatically-operated to apply the ticket in proper timed relation to the winding operation.

Still another object is to provide an apparatus of the type indicated which is reliable in operation to feed and sever the tickets and of simple and compact construction to adapt it for economical manufacture.

Further objects of the invention are set forth in the following specification which describes a a preferred form of the apparatus, by way of example, as illustrated by the accompanying drawings. In the drawings:

While the present invention may be applied to use with either manually-operated or automatic winding machines, it is herein described and illustrated in connection with an automatic bobbin winder of the type disclosed in the copending applications for United States Letters Patent,

Serial No. 231,044, filed September 21, 1938, by

C. D. Reynolds et al., now Patent No. 2,257,651 issued Sept. 30, 1941, and Serial No. 385,346, filed March 26, 1941, by C. D. Reynolds et ai., now Patent No. 2,302,715 issued Nov. 24, 1942. The machines illustrated in these prior applications: for patent are completely automatic in their operation to provide for donning empty cores or yam carriers, winding the yarn thereon, and domng the bobbins as they are completed. It is therefore desirable that a machine of this type shall be further adapted for earmarking or applying indicia to the bobbins automatically to identify them after theyhave been delivered from the machine. On the other hand, it is to be understood that the present invention is not limited to use with automatic winding machines, but may be applied to other types of winders for labeling the bobbins before they are doffed.

Referring to the drawings, in Fig. 1 a portion of a winding machine is illustrated comprising a frame or casing 2, and projecting from bearings therein is a rotary winding spindle 3. The wind ing spindle 3 carries a cup-shaped member 4 at its outer end for receiving the head h of a wooden core or bobbin D such' as used in either plain or automatic filling-changing looms. The opposite or tip end of'the bobbin b. is held in a similarv recessed member 5 on a spindle 6 mounted free to rotate in a bearing sleeve 1 supported by an upright bracket 8 attached to the end of a horizontal arm 9 projecting forwardly from the side of the machine frame 2, see Fig. 2. In the type of machine illustrated herein the yarn 1/ is wound on the core or wooden bobbin b by means of a thread-guide II] which has a relative traversing motion axially of the bobbin and is advanced progressively longitudinally thereof to deposit the yarn in courses of cross-wound coils which overlap at their forward ends. Consequently, the bobbin B grows by longitudinal extension, being formed with a conical base, a cylindricalbody portion and a tapered or conical tip end as indicated by dot-and-dash lines in Fig. 2.

The thread-guide I is carried on a reciprocabletraverse-rod l mounted to slide longitudinally in a bearing in the frame or casing 2 with its outer end supported by an outboard bearing l8 carried on the bracket 8, referred to previously as the support for the spindle bearing-sleeve I. The traverse-rod I5 is reciprocated longitudinally in its bearings by a suitable cam or similar means enclosed within the frame or casing 2 of the machine, but not herein illustrated as such traversing mechanism is well known to those versed in the art. The yarn y delivers from its source of supply, usually supported above the machine, but not herein shown, and feeds to the bobbin through an eyelet l1 in-the thread-guide HI. Connected to the thread-guide ill is a ro-- tatable contact-disk or traverse-wheel 20 mounted on a sleeve-like nutv 2| which is iriteriorly threaded to engage the screw-threads 22 on the traverse-rod is. It will be understood that the thread-guide HI is positioned adjacent the rearward or butt end of the yam-carrier or wooden bobbin b at the start of the winding and the traverse-wheel 20 is so related thereto that each time the guide makes a return stroke to the left, as viewed in Figs. 1 and 2, the periphery of the wheel will contact the yarn wound on the bobbin to turn the nut 2| through a part of a rotation to feed the guide forward to a slight extent along the traverse-rod. This method of advancing the layers of winding along the bobbin by the intermittent advance of the thread-guide is illustrated and described in the prior applications referred to above and well known to those versed in the art.

At the completion of the bobbin the threadguide [0 will be positioned at the forward or tip end of the bobbin when at the furthermost limit of its forward stroke and at this point the guide, or a part connected therewith, engages a stop or abutment to move the latter to cause actuation of the stopping mechanism of the machine, this mechanism being employed generally in machines which require manual dofiing and donning. In automatic machines such as described in the pending applications referred to above, the completion of the bobbin efiects initiation of the operation of means for dofilng the wound bobbin, donning an empty core or yarn-carrier, attaching the end of the yarn to the empty carrier, severing the yarn from the doifed bobbin, returning the thread-guide to initial winding position, and again starting the winding operation. The automatically-operated mechanism for performing these functions is described in the prior patent applications hereinbefore mentioned and is not referred to specifically herein as it forms no part of the present invention. Suifice it to state'that as the wound bobbin B is dofied by releasing it from the .driven winding spindle 3, it drops by gravity into a chute 23 arranged therebelow.

It is the common practice in winding filling bobbins to wind a few closely adjacent coils on the butt end of the core or carrier 12 at the beginning of the winding operation to form a bunch X which provides a reserve length of yarn in the shuttle to prevent misspicks when the filling is changed. The winding of such a bunch may be controlled by a separate thread-guide, commonly known as a bunch-builder, or the operation of the thread-guide may be restricted to wind with a short stroke at the beginning of the winding to cause the bunch to be wound, such devices being well known to those versed in the art.

In accordance with the present invention an identification tag or ticket T is attached to the bobbin by inserting it under the yarn strand y winding on the carrier b at the beginning of a winding operation to cause it to be gripped to the bobbin by the bunch windings. The ticket T as illustrated in the present drawings may consist in a length of paper strip detached from a continuous supply t and printed or marked to iden-- tify the particular yarn and/or winding unit on which it is wound. For example, the ticket T may have a particular color for indicating the count or size of the yarn with identifying indicia printed thereon, such as the characters A-8 illustrated in Fig. 2 of the drawings, for indicating the source of supply or the particular spindle on which the yarn is wound; or the reference character A may denote the machine on which the bobbin was wound and the numeral 3 indicate the particular spindle of that machine unit. It may be desirable in some instances to further identify the characteristics of the particular bobbin, such as the twist of the yarn or the particular lot in which the yarn was dyed and anyother characteristic which may be indicated by additional reference characters such as A-8I.

As illustrated in Figs. 1 and 2 the ticket-strip t is coiled to form a roll 25 which is mounted to rotate on a support or bracket 26 attached to the casing 2 of the winding machine. The supporting bracket 26, shown in Fig. 1,-ls of bifurcated form having spaced arms for receiving the roll 25 of paper strip t therebetween and having a spindie 21 extending between the arms and through the center of the roll to adapt the latter to rotate thereon. To apply the roll 25 for feedin the ticket-strip t it is only necessary to insert the spindle 2'! through the arms of the supporting bracket and center of the roll. Ad'iacent the bottom of the bracket 26 is an elbow-shaped arm 28, see Figs. 1 and 2, under which the strip if is inserted to guide it off from the roll 25.

Mounted on the machine frame or casing 2 adjacent the bracket 26 is a ticket-supplying mechanism 30 adapted to feed the ticket-strip t a distance equal to the length of a ticket T to be an plied and arranged to sever the ticket from the remainder of the strip. The ticket-applying mechanism 30 comprises a channel-shaped base,

3|, see Fig. 7. having a bottom wall 34. side walls 32 and 33 extending u wardly from the bottom wall and a rearward end wall 35. Preferably, the base 3! is made from a single piece of sheetmetal folded into channel-shape with the inner side wall 32 and end wall 35 considerably higher than the side wall 33. The base 3| is mounted on the machine by means of a bracket 36, see Figs. 1, 2 and 5, bolted to the end wall 35 and having an angular portion clamped between the bracket 26 and a ledge on the machine frame 2.

The bracket 36 as herein shown is so constructed and arranged as to position the open end of the channel-shaped base 3| at an acute an le to the axis of the bobbin b' adiacent the butt. end of the latter, see Fig. 2, and slightly inclined downwardly toward the axis of the bobbin. see Fig. 1. It is to be understood. however. that the base 3| may be mounted in any suitable relation to feed a ticket T into position to be bound to the bobbin by the coils of yarn wound thereon. For example, the base 3| may be placed parallel to the axis of the bobbin to provide for applying the ticket T in line with the barrel of the bobbin b as illustrated in Fig. 9.

A pair of curved springs 3'! and 38 are provided at the rearward end of the base 3! extendin downwardly and forwardly, see Fig. 5. to adapt the ticket-strip t to feed therebetween. The spring 31 is attached to the upper portion of the end wall of the base 3| and extends downwardly and forwardly therefrom to overlie the bottom wall 34 thereof. The spring 38 has its upper end attached to an angular bracket 39 fastened to the side wall 32 of the base 3| and extends downwardly and forwardly therefrom with its free end converging toward the free end of the spring 31. Thus, the pair of springs 31 and 38 provide a guide for the ticket-strip t and also act to tension the strip when the latter is fed therethrough to hold it against rearward movement. A leaf-spring 40 is attached at one end to the outsideface of the side wall 33 of the base 3! and shaped with an offset curved portion 4| at its opposite end forming a detent which slide 43 having a bottom wall- 44 and spaced side walls 45 of such dimensions as to adapt the slide to fit closely within the sides of the channelshaped base 3!. As illustrated most clearly in Fig. 7, the forward portions of the side Walls 15 of the slide 43 are of reduced height to provide vertical shoulders 46 intermediate the ends of the slide. ward side 32 of the base 3i with its bottom edge overlying the upper edge of one of the side Walls 45 of the slide 43 to restrain the latter from rising in the base while guiding its longitudinal sliding movement therein. The slide 53 is limited in its rearward movement by the engagement of its rearward end with the end wall 35 of the base 3i and its forward movement is limited by the engagement of the shoulders 86 intermediate its ends with lugs 48 extending inwardly to- A guide-bar 4'! is attached to the rear-- ward each other from the forward edges of the side walls 32 and 33 of the base.

Referring to Fig. ,7. the outer side wall 35 of the slide 43 has a vertical groove 69 adjacent its rearward end which is adapted to be engaged by the detent 4i projecting inwardly through the opening 42 in the side wall 30 of the base 31 and the bottom wall 4d of the slide has a sharpened cutting edge 5| on the forward side of a transverse slot or opening 50 therein. Welded or otherwise attached to the bottom wall d4 of the slide 43 at its rearward end is a leaf-spring 52 having its forward end curved upwardly slightly above the opening 50. The spring 52 is of relatively thin stock to adapt its upwardly curved end to yield to be depressed into the opening 53 in the bottom wall 44 of the slide 63. Projecting inwardly from one of the side walls 415 of the slide 43 is a lug 53 which functions for a purpose as explained hereinafter. As will be noted by ref erence to Fig. 7, the forward corner of the slide 43 is cut away and gradually rounded with the Side wall 45 terminating short of the end of the slide to permit free delivery of a ticket T therefrom as the bobbin B rotates with the ticket bound thereto.

Mounted to rock on the slide 43 is a gripping member 55, see Figs. 5 and 6. inthe form of a mally overlies the upwardly bent end of the spring 52, being curved downward y with its forward edge constituted as a knife or cutter for cooperating with the cutting edge 5| at the side of the opening 50 in the bottom of the slide 43 to function as shears. A resilient finger 6! is attached to the upper face of the horizontal arm 56 of the gripping member 55.by means of a screw 62 with its forward end curved downwardly toward the bottom wall of the slide 43 forwardly of the opening 50 to overlie a slight recess 63 formed therein.

The vertically-extending arm 51 of the gripping member 55 is curved rearwaldly at its upper end and projecting forwardly from its side is a finger 65 which may be formed integral therewith or attached to its forward face by an extension 64 welded or brazed thereto as shown in Fig. 7. The'finger 65 overlies the upper edge of the wall 33 of the base 3| to adapt it to engage therewith to limit the rocking movement of the gripping member 55 on the slide 43 in counterclockwise direction as viewed in Fig.- 5 during the major portion of the forward stroke of the slide. As will be noted by reference. to Fig. 7, the forward end ofthe side wall 33 of the base 3| is beveled off or inclined downwardly, as indicated by the reference character 66, to permit an added rocking movement of the gripping member 55 in counterclockwise direction at the end of the forward stroke of the slide 43. The rocking movement of the gripping member 55 on the slide 43 in ciockwise direction, as viewed in Fig. 5, is limited by the engagement of the resilient finger 6| with the lug 53 projecting inwardly from the side wall 45 of the slide.

The gripping member 55 is rocked on the pivotpin 58 and the slide 43 reciprocated with respect to the base 3| by the energization of an electromagnet having a U-shaped magnetic frame 10 attached to the side wall 33 of the base; Mounted on one arm 1| of the frame 10 is an electromagnet winding in the form of acoil 12, the wall 33 f the bracket 3| being recessed to provide an opening for the bottom portion of the coil. The

V opposite arm 13 of the frame 10 has a bifurcated end for receiving the reduced end 14 of an armature 15. The armature 15 is pivotally mounted on the arm 13 of the frame 10 by means of a pin 16 extending through the bifurcations and the reduced end 14 of the armature. The lower free end of the armature 15 extends forwardly in the form of a plunger 11, see Fig.- 7, the bottom face of which is of arcuate shape to adapt it to cooperate with the corresponding arcuate upper face of the arm 1| of the frame 10. The armature I is adapted to be rocked in c0unterclockwise direction away from the arm 1| of the frame by means of a hairpin-shaped spring 18, see Fig. 5, coiled about its pivot-pin 16 with one end engaging the'arm 13 of the frame 10 and its opposite end engaging the armature 15. Upon energization of the magnet the plunger '11 is drawn into the coil 12 by magnetic attraction causing the armature I5 to rock on its pivot-pin 16 in clockwise direction as viewed in Figs. 5 and 6.

A sheet-metal member 83 mounted on the side of the armature 16 by means of screws 82 has a laterally offset intermediate portion 84 extended in a forwardly-projecting arm 85 which terminates in a downwardly inclined finger 86. Pivotally mounted on a pin 92 projecting from 9| coiled about the pivot-pin 92 with one endbearing against the finger 90 and its opposite end bearing against the arm 85. The member 83 is so constructed and arranged as to position the fingers 86 and 90 on opposite sides of the upright arm 51 of the gripping member 55 when the slide 43 is in its rearmost position.

Upon energization of the magnet coil 12 to rock the armature on its pivot 16 the finger 90 on the bracket 83 engages the rearward side of the upright arm 51 of the gripping member 55 to thereby rock the latter in counterclockwise direction to cause the resilient finger 6| to grip the ticket-strip t against the bottom wall of the slide 43. Since rocking movement of the gripping member 55 is limited by the engagev ment of its longitudinally-extending finger 65 the arm 85 of the member 83 is an auxiliary member will engage the forward face of the upright arm 51 of the gripping -member 55 to rock it in clockwise direction to release the ticket-strip t and return the slide 43 to initial position.

The energization of the magnet coil 12 may be controlled in any suitable manner, but pref erably it is under the control of a controller of the tyne illustrated and described in the Reynolds et al. applications referred to above. Suflice it to state herein that the controller comprises a cam-shaft 96, see Fig. 8, having a cam 91 thereon for operating a switch 98 in an electric circuit including the magnet coil 12. Thus, at a particular time during the rotation of the shaft 96 the cam 91 closes the switch 98 to energize the magnet coil 12. The controller cam-shaft 96 is adapted to rotate through one complete revolution and has a series of cams as indicated in Fig. 8 for controlling branch circuits in timed sequence to arrest the winding operation upon completion of a bobbin, doff the wound bobbin B, don an empty bobbin 1), start the winding of a new bobbin, and attach a ticket thereto. Fig. 8, illustrates parallel branch circuits adapted to control the donning of an empty bobbin b and the starting of a new winding operation. The circuit for controlling the don- .ning of an empty bobbin b comprises a cam I00 on the control shaft 96. a switch |0| and a magnet winding I02, while the circuit for starting a new winding operation comprises a cam I03 on the control shaft 96, a switch |04 and a magnet winding I05. It will be understood that the cams I00, 91 and I03 are so arranged as to actuate the switches MI, 98 and I04 in timed sequence whereby an empty bobbin b is donned, a ticket T fed between the yarn strand y and the bobbin b and a new winding operation started to cause the ticket to be gripped between the coils of the winding strand and the bobbin. One form of the invention having been described in detail the mode of operation of the device is explained as follows:

A roll 25 of .the ticket-strip t having the proper color and identifying indicia printed thereon is mounted on the bracket 26 between its bifurcated arms and the pin 21 inserted through the arms and center of the roll. It will be understood that-a similar roll 25 having the proper identifying indicia is sufiplled to each unit of forwardly from the slide as illustrated in Fig. 2.

Considering that the machine is operating, upon completion of the winding of a bobbin B the thread-guide ID will be at the outer end of the traverse-rod I5 and as the latter makes a forward stroke the guide, or a part attached thereto, will strike an abutment or other means to move the latter to set into operation the doifing and donning mechanisms of the machine. The various mechanisms for this purpose are under the control of electromagnets adapted to be energized by circuits which are closed by the several cams on the controller-shaft 95, indicated in the diagrammatic view, Fig. 8. The controller-shaft 95 is connected to rotate through a clutch or other. means shown and described in the Reynolds et al. applications referred" to previously herein. As the first step in the dofiing and donning operation the spindle-cup 4 is retracted to release the wound bobbin B which drops by gravity into the chute 23. An empty bobbin or yarn-carrier b is then transferred into position betweenthe spindle-cup 4 and the recessed member 5 on the opposed spindle 6 with the strand of yarn y trailing from the wound bobbin B and positioned between the spindlecup and the butt end of the empty bobbin. The cam I on the controller-shaft 96 then acts to release the switch |0| to open the circuit to h the electromagnet winding It to release the spindle-cup 4 whereby it is projected forwardly by means of a spring. not herein shown, to grip the empty bobbin between the cup and the recessed member on the spindle 5; the yarn strand y being thereby clamped against the end of the bobbin. The winding spindle 3 is then started to rotate through the means of suitable clutch-devices, not herein shown, whose action is initiated by electromagnetic means, as described in detail in the pending application Serial No. 385,346 referred to above. As the winding spindle 3 is driven to rotate the bobbin b the trailing end of the yarn leading to the doffed bobbin is severed automatically and at this juncture the bunch-building means comes into action to restrict the traverse of the yarn as the threadguide II) is reciprocated by the traverse-rod I5 coincidentally with the rotation of the winding spindle.

spindles 3 and 6 the cam 91 on the controllershaft 95 functions to close the switch 93 to complete the circuit to the electromagnet winding 12 of the actuator for the ticket-applying means 30. Energization of the electromagnet winding .12 causes the armature 75 to be attracted and rocked in clockwise direction, as viewed in Fig. 5, to actuate the strip-feeding means to advance the strip t a distance equal to thelength of a ticket T. This rocking movement of the armature '35 causes the finger 90 at the end of the arm 81 to engage'the upright arm 51 of the gripping member 55 to rock the latter on its pivot-pin 58 and thereby press the forward end of its arm 56 against the ticketstrip 't to grip it against the end of the spring 52 on the bottom wall 44 of the slide 43. During this action the slide 43 is restrained momentarily from longitudinal sliding movement along the base 3| by the engagement of the detent 4| at the end of the yieldable spring 40 with the groove 49 in the side of the slide, see Fig. '7. The restraint of the movement of the slide 43 will cause the finger 90 to rock slightly against the tension of its spring 9|, this yieldable action of the finger being designed to cushion the shock caused by the rapid movement of th armature 15 as it is rocked by the attraction of the magnet winding 12. It will be understood that the yielding action of the finger 90 is limited by the engagement of its lug 88 with the upper edge of the arm carried On'the armature 15. The gripping member 55 is limited in its rocking movement by the engagement of its forwardly-extending finger 65 with the upper edge of the side wall 33 of the base 3|, and immediately this occurs the finger 90 on the armature I5 will cause the gripping member 55 to slide forwardly along the base 3|. As the full force of the armature i5 is applied by the finger 90 against the upright arm 51 of the gripping member 55 to slide the slide 43 forwardly the detent 4| is released from the groove 49 in the side of the slide.

The forward movement of the slide 43 is limited to a distance equal to the length of the ticket T to be applied as the shoulders 45 on the side of the slide engage with the lugs 48 .at the end of the base 3|. As the slide 43 approaches this limit in its forward movement the finger 85 on the gripping member 55 will ride down the inclined or beveled edge 66 on the forward wall 33 of the base 3| to permit the gripping member to rock to a further extent in contraclockwise direction. This additional rocking movement of the gripping member 55 causes the forward end of its horizontal arm 56 to be forced downwardly across the cutting edge 5| on the side of the slot 50 in the slide 413 to sever a length of the strip 1. to form a ticket T which is held in extended position on the slide by the engagement of the resilient finger 6| therewith. During this latter rocking movement of the gripping member 55 the spring 52 therebeneath yields as indicated in Fig. 6 of the drawings. At this stage in the operation of the ticket-applying means the end of the spring finger 6| will overlie the top of the severed ticket T and press the latter into the depression 63 at the end of the bottom wall of the slide 43.

The ticket T severed from the strip '6 is thus held momentarily in position overlying the top of the bobbin b adjacent the base thereof as indicated in Figs. 3 and 6 of the drawings. At this juncture the end, of the strand y has been cause it to be carried around therewith and withdrawn from the applying device 30. Nowpas the rotation of the bobbin b continues the strand of yarn 1 leading from the thread-guide ID will be wound around the bobbin overlying the ticket 'I as indicated by dot-and-dash lines in Fig. 6 to securely fasten it in place by the coils of winding in the bunch X. As the bunch X is completed the yarn y is released from the bunchbuilding means to allow the thread-guide It to traverse it to the full extent as indicated in Fig.

2 of the drawings to form the service windin on the bobbin b. The whole length of the ticket '1 will thus be bound around the bobbin 2 except for a slight portion at its end which is left projecting to display the 'indicia thereon. The indicia may comprise one or more characters which are duplicated at short intervals along the length of the strip t so that at whatever point the strip is severed there will be at least one set of characters showing as indicated in Figs. 2 and 9.

The cam 91 .which controls the operation of the ticket-applying means is so constituted and its operation ,so timed as to cause it to release the switch 98 to open the circuit to the magnet winding I2 immediately the ticket T has been delivered to the winding bobbin. Consequently, the deenergization of the magnet winding '52 will effect release of the armature 15 to cause it to be rocked in counterclockwise direction under the action of the spring 78 to return it to itsinitial inoperative position shown in Fig. 5. During this rearward rocking motion of the armature 15 the finger'86 carried thereby will engage the upright arm 57 of the gripping member 55 to first rock the latter in clockwise direction on the slide 34 and thereafter slide the slide rearwardly until its ,end brings up against the wall 35 of the base 3! as the detent 4| is engaged with the groove 49 in the side of the slide, see Figs. 5 and 7. The rocking movement of the gripping member 55 in the manner last explained is limited 'by the engagement of the resilient finger 6| with the lug 53 on the side wall 45 of the slide 43, see Fig. 5. The initial rocking movement of the gripping member 55 raises its arm 56 to release its end from the strip i so that it will pass over the strip t as the slide 43 returns to its rearward position; the strip t being meanwhile held from retrogressive movement by the gripping action of the two springs 31 and 38 with the forward end of the strip advanced slightly. beyond the end of the base 3|, see Fig. 5. Consequently, the strip i will be fed forwardly again at the next operation of the gripping member 55 in the manner as previously explained. The machine will continue to operate in the manner explained to arrest the rotation of the winding spindle upon completion of each bobbin B, doff the wound bobbin, don an empty bobbin b and attach the strand thereto, with the present device acting in timed sequence to deliver a ticket T in position to be gripped to the bobbin by the winding of the strand thereon as the bunch winding is started.

It will be observed from the foregoing specification that the present invention provides a simple and compact device for automatically delivering tags, tickets or similar identifying ele--. ments and applying them to the bobbins as they are wound in the machine. The device is of such form and construction as to adapt it to be employed as an attachment for application to machines already in use by supplying the necessary electrical connections. The device is entirely automatic in its operation and reliable in per'-. forming its intended functions while being relatively inexpensive to manufacture.

While a preferred form of the device is herein illustrated and described, it is to be understood 'that its mechanism may be modified and its application to use may be varied without departing from the spirit and scope of the invention. That is to say, the ticket-serving device may be arranged to apply the ticket to the bobbin in different relationship from thatherein shown, for

example by serving a gummed strip for attachment to the wooden base of the bobbin as the latter is gripped to the spindle-center or cup by which it is rotated.
