BBAID HANK-WINDING MECHANISM.

Application filed March 2 5, 1926. Serial No. 97,224..

This invention was designed for making commercial packages of braids of artificial horsehair, rayon, and other materials, es pecially intended for the millinery' trade. That trade demands braid in packages of uniform length, for instance one hundred forty four yards, preferably made up in a plurality of long parallel coils, in which the braid is continuous from coil to coil. The purpose and effect of this invention is to provide a mechanism for winding and measuring such packages with a minimum amount of attention on the part of the operator and to present each completely wound hank with-its coils in such relation that they may be bound together by manually applied bands of strin before removal of the hank from the winding mechanism.

However, it is to be understood that my invention maybe utilized in winding tapes, ribbons, or any narrow webbing or cord, in such associated coils.

My invention includes the various novel features of construction and arrangement hereinafter more definitely specified.

In said drawings; Fig.1 is a plan. view of a mechanism conveniently embodying my invention. 1

Fig. II is an elevation of the left hand 'side of the mechanism as shown in Fig. I.

Fig. III is an elevation of the right hand end of said mechanism as shown-in Fig. 11; being the lower end thereof as shown in Fig. IV .is a plan view of the completed hank indicated in dotted lines in Fig. I.

Fig. V is an elevation of the right hand side of said hank as indicated in FigIV.

Fig. V1 is an inverted plan view ofsaid hank as shown in Fig. TV.

Fig. VII is a fragmeijitary plan view of the winding head shown in Fig. I, but with the movable blade retracted to position to release the hank from said head.

In said figures; the frame 1 is provided with

bearings

2 and 3 for the winding shaft i, which is provided with means, for instance, the belt wheel 5 and, or, the crank handle 6, whereby it may be rotated. Asindicated by the dotted lines'in Fig. I; the braid 7 is wound in a hank 8 on the winding head 9 which is detachably secured on said shaft 4-, at one end thereof, conveniently by the set screw 10. Said head includes a bar extending in diametrical relation with said shaft and

havin'g slots

11 and 12 extending 'center to center distance between said blades may be adjustably varied, to precisely predetermine' the length of braid to be wound in said hank 8; say 14 1 yards.

Each of said blades has an axial'd'uct 17 leading to a groove 18 in its radially outer edge, parallel with the axis of said shaft 4:, and in line with a radial slot 19 in a circular, braid abutment, flange 20. Each blade also has a spring clip 21 at the outer end thereof which may be used to secure the end of a string extending through said duct and groove, to be used to bind the hank 8, as hereinafter described.

Saidblade 13 has the pin-22 so spaced in parallel relation therewith, adjoining the abutment flange 20, that the initial end of the braid 7 may be wedged between said pin and blade to secure it at the beginning of each winding operation. Said blade 13 may be rigidly secured in adjusted radial posi-. tion in said head 9, by its nut 16. However, the other blade 1% has its screw threaded shank 15 extending through the slot 28 in the carriage 24, in which it is secured by its nut 16; so as to be movable toward said shaft 1 to release the hank 8. Said carriage is lit-ted to reciprocate in the slot 12 in said bar 9 and l provide means arranged to shift said carriage 2a and its blade 14 in said bar, including the crank 25 carried by the shaft 26 which extends transversely in said bar and ispivotally connected to one end of the link 27 which has its other end connected to said carriage 24L. Said crank 25 may be rocked by the operating handle 28 on said crank. shaft 26; and the stop pin 30 on said bar limits the movement of said handle; so that said crank 25 and link 27 are operable as atoggle connection between said carriage and bar, and said carriage is normallymaintained at the outer limit of its movement with said operating handle 28 against said stop pin, and said link 27 pastthe dead center; so that said blade 14 is not accidentally displaced by the strain of wrapping the hank of braid 8 around said blades.

The abutment plate 31 is carried by said bar 9 to which it is rigidly attached by the studs 33, and extends between said blades 13 and 1-l in alinement with the braid abutspaced relation on the plate 29 which BX- tends transversely in rigid connection with one end of said slide bar 35. The pair of braid guide rollers l1 have flanges l2 to receive the braid 7 between them and are mounted to turn idly on the respective roller shafts 38 in positions determined by the axially adjustable collars 43, which are rigidly connected with said shafts upon axially opposite sides of said braid guide rollers 41. The friction disks d5, conveniently formed of vulcanized fiber, are interposed between said guide rollers 41 and said collars 13; so that movement of said braid 7 toward said winding head is retarded by the resistance of said rollers ll to turning movenent. Moreover, I provide the braid tension device, including the stationary guide plate 47 which is rigidly mounted upon the bracket 48 which is detach-ably rigidly connected with said slide bar 35, by the set screw {Said plate 47 has two pairs of studs 51 fixed therein, forming a path between them for the braid 7 which is frictionally engaged by the pressure plate 53 which is pressed to arc said plate 47 by the spring 5d. Said bracket l8 lo so set on said bar that the passageway between said

tension plates

47 and 53 is in alinement with the passageway between the guide flanges 42 on said guide rollers 4L1.

I provide means arranged to shift said slide bar 35, step by step, axially, with respect to said winding head. 9, including a series of ratchet teeth 55, on the under side of said bar 35, and the pawl 56 which is conveniently formed of spring sheet metal and arranged to selectively engage said teeth 55. Said pawl 56 is rigidly connected at one end, by the screws 57, with the pawl plunger 58 which is mounted to reciprocate in said bearings 36 and 37, parallel with said slide bar 35. The spring 60 encircling said plunger 58 normally tends to thrust it to the uter extreme of its range of movement, and the effective pressure of said spring may be adjust-ably varied by shifting the pair of jam nuts 61 on said plunger in engagement with the screw thread 62 on the latter,

plunger into engagement with the detent r notches in said bar 35. Said detent '66 is provided with the cross pin 71 which normally extends in the diametrically opposite slots 72 in said tubular bearing 68 and presents said detent in position to engage said notches. knob 73 by which it may be retracted and rotated to turn said pin 71 aside from said notches 72, to hold said detent in idle posi tion, whenever it is desired to freely slide said bar 35.

However, the function of said detent 66 is to normally prevent accidental displacement of said slide bar 35 carrying said braid guide rollers ll, but to yield and permit said bar to be shifted to the successive axial positions corresponding with the successive coils of the braid 7 in the hank 8, as indicated in dotted lines in Fig. I, when said bar 35 is thrust outwardly by said pawl 56; In order to effect the proper movement of said pawl plunger 58, in proper time with the winding operation of said shaft l; I provide the latter with the worm 75 between said

bearings

2 and 3 on the frame 1, in engagement with the worm gear 76 which is rigidly connected with the end of the cam shaft 77 which is journaled in the bearings 78 and 79 on said frame 1, and provide the opposite end of said cam shaft with the pawl cam 81 arranged to engage the cam plate 82 projecting from said pawl plunger 58 s as to retract said plunger, against the stress of its 7 spring 60, and release said plunger to be operated by said spring, once each revolution of said cam shaft 77. Only the hub of said worm gear 76 appears in Flg. I, but it is indicated in connection with the worm gear 75 in Fig. III. When thus retracted and released, said plunger 58 is moved outwardly by its spring 60, with said pawl 56 engaging a ratchet tooth 55 on the under side of said slide bar 35; so that said slide bar is shifted outwardly against the pressure of said detent 66, forcing the latter out of the notch 65 in said slide bar with which it is engaged, and permitting it to return into the next succeeding notch. Such movement shifts the guide rollers ll outwardly to the extent of the width of the braid 7, so as to direct the latter to form the next succeeding coil in the hank 8.

' Th tension upon said. braid 7 induced by I provide said detent with the parallel with said winding shaft 4.

the friction disks upon said guide rollers 41, and by the passage of the braid between said

tension plates

47 and 53, is constant, although subject to adjustment as above described; However, as each coil of braid is wound over said

blades

13 and 14, an in creasing extent of braid is required for each convolution. In other words; with the winding shaft 4 turning at a constant speed, the braid 7 must be wound in the coils at a'speed which increases from the first to'the last convolution in each coil. Therefore, I prefer to also provide said mechanism with means whereby the tension upon the braid may be automatically varied, in correspondence with the speed at which the braid is taken up in the winding operation; so that the tension upon the braid is decreased as its speed of travel is increased in the winding of each coil. In the form shown; such means includes the fork 84 having the pair of cylindrical tines 85, in spaced relation, and engaged with the braid 7 between said tension plate 53 and .said guide rollers 41. Said fork is carried by the rock shaft 86 which is journaled in the brackets 87 on said frame 1, Said fork shaft 86 has the crank 88 connected by the link 89 and pivotal coupling 90 with the fork actuating lever 91 which has the fulcrum 92 on said frame 1 and is provided with the spring 93 connecting said fork lever with said frame and tending to shift said lever and fork to one extreme of their range of movement. Said fork actuating lever 91 has the cam stud 95 arranged to cooperate with the crown cam 96 on said cam shaft 77, to gradually shift said fork lever .91 and turn said fork from one extreme to theother during each revolution of said cam shaft 77; one such revolution being effected during the winding of eachof said coilsof the braid 7 in the hank 8, and with the effect of varying the tension upon the braid as above contemplated.

VJ hen the hank 8 is completelywound, the machine is stopped and the binder tie 97, conveniently consisting of a band of string, is tightly wrapped around the hank 8 and knotted at 98 as shown'in Fig. IV; the braid 7 is then 'cut with the last end thereof projecting beyond said tie, toward the upper portion of Fig. IV, and the cut end of the braid 7 then tucked under said tie 97 to secure it, as shown in said figure. I find it convenient to provide each hank with at least two other binder ties 99 which are tightly wrapped around it and knotted at 100. I a-lsofind it convenient to provide each hank with a hanger tie 101 formed of a loose bight of string, knotted at 103.

The string 105 for said binder ties 97 and 99 and hanger 101 is convenientlycarried upon the two spools 106 which are journaled said winding head 9, respectively

adjacent tosaid'blades

13 and 14, and provided with pins 109 and Washers 110 to prevent their accidental displacement. Said string is directed from the respective spools through the adjacent ducts l7 and grooves 18 of the

respective blades

13 and 14 and the free ends of the strings are temporarily fastened under the spring clips 21 on the respective blades.

Said mechanism is operated as follows: The mechanism being in the position shown in Figs. I and II; the braid 7 is drawn from a supply roll or reel and threaded between the

tension plates

47 and 53 and around the fork tines 85 and over and under the respective guide rollers 41, as shown in FigII, and the forward end of the braid caught between said pin 29 and the adjacent face of the blade 13. Th'ereupon, said shaft '4 is turned in the direction of the arrow shown in Fig. II and said braid wound in acoil adjacent to the flanges 20 and plate 31 until thirty convolutions have been wound in that initial. coil of the hank '8. During such winding, the crown cam '96 gradually shifts said fork lever 91 and turns said fork. 84' to vary the tension on said braid in compensation for the increased speed of traverse of the braid incident to the increased extent of the convolutions in said coil. As the Winding ofsaid coil is completed, the crest of said crown cam 96 is carried past said stud 95, thus releasing said lever 91 from the extreme position to which it has been thrust, and permitting its spring 93 to return it to the initial position shown in Fig. I. Con tempora'n-eously, said pawl plunger 58 having been retracted by the pawl cam 81 and released, is thrust by its spring 60 so as to engage said slide bar '35 by the pawl 56 and shift said bar 35 outwardly to the extent of one of its ratchet teeth 55, against the frictional engagement of said detent 66 which falls into the next succeeding-notch 65 to, the right in Fig. I. Continued rotation of said, winding shaft 4 and head 9 winds the braid in asecond coil on said head 9, adjacent tosaid first coil; the braid 7 crossing from one coil to another, as indicated by the diagonal lines 112 in Fig. VI. The operation is continued until seven coils are wound to form the hank 8 and, thereupon, the winding operation is suspended while the hank is bound with the string ties, as above described. Thereupon, the operation above described is "repeated to form another hank 8;

Although I have found it convenient to form "hanks 8 of seven coils, each containing thirty convolutions; it is obvious that such specific numbers of coils and convolutions are not of theessence of my invention;

,,t h e apparatus above described being adjustg ,able .to vary the same.

on the splndles 107 rigidly projecting from Therefore, I do not desire to limit myself 7 to the precise details of construction and arrangement herein set forth, as it is obvious that various modifications may be made therein without departing from the essential features of my invention, as defined in the appended claims.
