UNITED STATES PATENT ori-ica BOBBIN-IDENTIFYING DEVICE FOR WINDING MACHINES Ralph L. Chisholm,-West Newton, Mass., assignor to Universal Winding Company, Cranston, R. I., a corporation of Massachusetts Application July 2, 1941, Serial No. 400,870

14 Claims.

l tify iilling yarn by marking the bobbins with crayon or chalk to indicate diiierent types and -counts of the yarn and also to identify the machine or department in which the yarn is processed or handled. Usually, the operator of the machine marks the yarn on the bobbin by drawing a piece of chalk or crayon over the surface of the bobbin, butthis operation has certain disadvantages as it is liable to -cause the chalk dust to iniiltrate into the mechanism ofthe machine to interfere with its proper functioning,

The practice of marking the bobbins as now generally used is for the purpose of preventing mixed counts of lling yarn going to the same loom and becoming incorporated in the fabric. In such case the' difference in the size or count of the lling does not become evident until the cloth is woven and therefore it results in spoilage or 'seconds in the product of the 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 theyI can be traced to the machine in which they were wound or to the department in which the yarn was processed. In some cases diierent 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 or another type are placed therein. Most mills handle more than one count of yarn as they are `doed therefrom with one or more distinguishing colors to prevent mixed counts from being woven in the loom; and further, to trace 'the steps in the processing of the yarn in diiierent departments of the mill to correct defectsv or deficiencies in its manufacture.

Another object of the invention is to provide bobbin-identifying means which may be employed as an attachment on Winding machines in which the bobbins are doffed either manually or automatically upon completion of the winding.

Another object oi the invention is to, provide means which may be applied to winding machines to mark the bobbins produced therein with different colors applied by wicks fed from reservoirs containing fugitive ink or dye liquid..

Anotherobject oi the invention is to provide means for marking the bobbins with diierent co1- at the same time and las the counts must be kept separate it is an object of the present invention to provide automatically-operated means for cred chalk or crayons after they have been dotted from the machine and during their delivery therefrom.

Further objects of the invention are set forth in the following specification which describes several forms of construction of automatic bobbin-identifying means as illustrated by the accompanying drawings. `In the drawings:

Fig. l is a side elevational View of the essential elements of a winding machine showing a chute arranged below the Winding spindle for receiving the defied bobbins and illustrating one form of automatic bobbin-marking device' as applied thereto;

Fig. 2 is a plan view of the same;

Fig. 3 is a transverse sectional view through the bobbin chute and marking device Itaken on line 3-3 of Fig. 2;

Fig. 4 is a similar transverse sectional view illustrating the manner in which the bobbin descends through the chute and is marked by a wick or wicks leading from a reservoir containing ink or dye liquid; l.

Fig. 5 is a view similar to Fig. 4 illustrating the use of crayons for marking the yarn on the bobbins: and

Fig. 61s a view of a conventional type of bobbin illustrated as marked with three different identitying colors.

While the present invention may be applied to use with either manually-operated or automatic winding machines, it is herein described and il,- lustrated in connection with a machine of the type disclosed in-United States Letters Patent No. 2,257,651, dated September 30, 1941, and No. 2,302,715, dated November 24, 1942. chine illustrated in these prior patents is completely automatic for donning empty cores or yarn-carriers, winding the yarn thereon, and dofflng the bobbins as they are completed. It is therefore desirable that a machine of Athis type shall be further adapted for marking the bobbins automatically to identify them after they have been delivered from themachine. 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 marking the bobbins before they are doiled or as they are doffed manually.

Referring to the drawings, in Fig. 1 the frame 2 or casing of the winding machine is indicated in section and projecting from bearings therein is a rotary winding spindle 3 at the end of which is a cup-shaped member 4 for receiving the head h of a wooden core or bobbin b such as used in automatic filling-changing looms. The opposite or tip end of the bobbin b is held in a similar recessed member 5 on a spindle 6 mounted free vto rotate in a bearing sleeve 'I sup-ported by an upright bracket 8 attached to the end o-f a horizontal arm 9 projecting forwardly from the side of the machine frame 2, see Fig. 2. In the type of machine herein illustrated the yarn y is wound on the core or wooden bobbin b by means of a thread-guide I which has a relative traversing motion axially of the bobbin and is progressively advanced longitudinally thereof to deposit the yarn in courses of cross-wound coils which overlap at their forward ends. In this way the bobbin grows by longitudinal extension, being formed with a conical base, a cylindrical body portion and a tapered or conical tip end.

The thread-guide I0 is carried on a reciprocable traverse-rod I mounted to slide longitu- AAdinally in a bearing in the frame or casing 2 with its outer end supported by an outboard bearing.

I6 carried on the bracket 8, referred to previously asthe support for the spindle 6. The traverserod l5 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, supported above the machine but not herein shown, and feeds to the bobbin through an eyelet I'I in the thread-guide I D. Connected to the thread-guide I0 is a rotatable contact-disk or traverse-wheel 20 mounted on a sleeve-like nut 2| which is interiorly threaded to engage the screw-threads 22 on the traverse-rod I5. It will be understood that the thread-guide I 0 is positioned adjacent the rearward or butt end of the yarn-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 2l through a part of a rotation to feed the guide forward to a slight extent along the traverse-rod. This method of advancing thevlayers of winding along A,the bobbin by the intermittent feed of the thread-guide is illustrated and described in the prior patents referred to above and well known to those versed in the art.

At the completion of the bobbin the threadguide I0 will be positioned at Vthe 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 causeactuation of the stopping mechanism of the machine, this mechanism being employed generally in mai .chines which require manual doillng and donnng. In automatic machines such as described i in the prior patents referred to above, the completion of the bobbin effects initiation of the operation of means for dofiing the wound bobbin,

donning an empty corev or yarn-carrier, severing the yarnfrom the doffed bobbin, attaching theend of the yarn to the empty carrier, 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 patents hereinbefore mentioned and is not referred to specifically herein as it forms no part of the presvent invention. Suffice it to state that as the wound bobbin B is doffed by releasing it from the driven winding spindle 3, it drops by gravity into a chute 25 arranged therebelow.

As illustrated in Figs. 1 to 4, inclusive, the v j with a yarn-trap in the form of a pivoted plate or shelf 28. The pivoted plate 28 is normally held in horizontal position, as shown in Figs. 3 and 4, by means of a spring 29 coiled around its pivotpin 30 with one end hooked around the top of the chute and its opposite end bearing against the under side of the plate. The purpose of the yam-trap or plate 28 is to catch the bobbin as it drops from the winding spindle and guide the length of yarn trailing therefrom to carry it into position across the forward face of the spindle-cup 4 to position it to be clamped against the end of the empty bobbin or yarn-carrier when the latter is donned. The yarn-trap or plate 28 also carries a knife, not herein shown, for severing the yarn after it has been connected to the empty bobbin and the latter starts to rotate to wind on the yarn.

Below the yarn-trap or plate 28 is another pivoted shelf or gate 3|, shown by dotted lines in Fig. 1, onto which the wound bobbin drops and is retained momentarily before being delivered into the receiving box or receptacle 21. The gate 3l is normally supported in inclined position and isadapted to be released by suitable instrumentalities, not herein shown, to allow the the bobbin to drop into the box 21 with its butt or head end falling first. While these last two devices are shown in the present drawings and described briefly herein, they form no part of the present invention and are not essential to the operation of the bobbin-marking devices. In fact, they may be absent in machines in which the bobbins are released'and dropped by hand through the chute 25 into the receptacle 21.

The bobbin-identifying device of the present invention may take different forms and as illustrated in Figs. 1 to 4, inclusive, it comprises a container or reservoir 32 for fugitive ink or liquid dye f and wicks 35 for applying the fluid to the bobbins. The reservoir 32 is fastened to the side of the chute 25 by means of bolts 33 passing through a bracket or support 34 welded or soldered to the forward side of the reservoir. The reservoir 32 may be provided with one or a plurality of wicks 3l immersed in the fluid l and supported in troughs or holders 38 projecting through an opening 31 in the side of the chute 25 with their ends adapted to contact the bobbins as they descend therethrough. Figs. 1 and 2 illustrate the reservoir 32 as divided by partitions 33 and 39 into three separatecompartments for containing three diii'erent colors of ink or dye liquid, a greater or lesser 'number being used in other instances. The reservoir 32 is formed with a. neck or spout 4l directedtoward the opening 31 in the side of the chute 25 and is provided with a hinged cover 43 mounted on a cross-pin 44 v to adapt it to be swung open into the position illustrated by dash! lines in Fig. 3 for filling the separate compartments with the dye liquid.

Fastenedto a ange 45 at the end of the spout 4I is a wire bail 46, to which are pivoted a series of the shallow troughs 38 -with their sides inclined toward each other at their outer ends. The troughs 36 have lips 48 projecting inwardlyfrom their sides at their forward ends, ,see Figs. 3 and 4, to adapt them to partly encompass and compress the wicks 35 slightly at the ends projecting beyond the ends of the troughs. Helical springs 49 anchored at one end to the hinge-pin 44 for the cover 43 have their opposite ends hooked through openings in the sides of the troughs 36, thereby tending to maintain the latter in positionslightly inclined to the horizontal, as shown in Fig. 3, with the inner ends ci' the troughs engaging the end of the spout 4I to limit their upward movement. The springs 49 permit the troughs 36 and the wicks 35 to swing downwardly as shown in Fig. 4 as the bobbins B descend through the chute 25 and contact the ends of the wicks to pass thereacross.

In automatic bobbin winders of the type disclosed in the prior patents'previous'ly referred to the spindle-center or cup 4 is withdrawn axially to release the bobbin B at the completion of the edge of ears 60 on the holders l5 to ywhich the lower end of the springs 51 are attached to regulate the position of the holders. Pieces of chalk orV crayon 58 of different colors are held on the holders 55 by means of clamping fingers indicated at 8i, with the ends of the crayons projecting toward the opposite side of the chute and at a distance therefrom slightly less than the diameter of that part of the bobbin to be marked. The crayons in this modified form of construction act inthe same manner as the wicks previously described by being drawn across the periphery of the bobbin B as it drops through the chute to thereby apply the dierent identifying indicia thereto. Since the crayons are arranged below the winding mechanism of the machine and enclosed within the chute 25 the dust or particles dropping therefrom will not insinuate into the operating mechanism of the machine and therefore the use of the crayons in place of the dye liquid is not of disadvantage.

winding and as the bobbin falls into the chute'25 it depresses the yarn-trap or plate 28 as indicated by thedash lines in Fig. 3. The bobbin B will then continue its descent downwardly along one side of the chute 25 and as it encounters the ends of the wicks 35 it will swing their holders or troughs 36 downwardly as indicated in Fig. 4, thereby causing the wicks to wipe across the rearward portion of the bobbin to mark it with identifying colors as provided by the variously colored fluid in the reservoir 32. The bobbin#` thus marked drop down into the receptacle or box 21 and when the latter is filled iut is removed to transport the bobbins to another location such as the weave room of the mill.

Fig. 6 illustrates the wound bobbin as being marked with three different colors, red, yellow and green, to indicate the size or count of the yarn and other particulars, for example, in what department the yarn was spun or processed, or in other cases the particular machine in which the bobbin was wound. The colored markings remain von the yarn when it is woven into 'the cloth, but when the fabric is later processed or finished, the dye,being fugitive, will disappear on treatment with water or other liquids.

Fig. 5 of the presentv drawings illustrates a modified form of `device for marking the bobbins as they descend through the chute 25. In this embodiment of the invention a series of crayonholders 55 are pivotally mounted on a bracket 56, bolted to the side of the chute 25. The holders 55 are maintained in inclinedposition in relation to the horizontal by helical springs 51 It will be observed from the foregoing specification that the present invention provides means for applying identifying indicia to the yarn on filling bobbins or other forms of packages whereby to indicate the character of the yarn and its source of manufacture. While the device 'is herein shown as embodied in several diiferent forms of construction, it is to be understood that various other modifications may be made in the structure and arrangement of the parts of the device and the manner of applying it to use without departing from the spirit or scope of the invention.
