(01. ass- 2) Claims.

This invention relates to a simple dorm of winding device by which yarn coming off a skein may be readil wound into a ball. The com s'truct i'on is simple, inexpensive, light, and cornpact so that the winder is admirably suitable for home use. I

It is an important object or our invention to provide, in a winder of the characterspecifie'd, means for guiding the yarn or other like materialback and forth lengthwise of a revolving spool so that the yarn will be laid evenly as the winding progresses; to maintain in a simple and effective manner an even tension on the yarn so that the resultant windings on the spool will make up into a ball which is free of hard and soft spots; to direct the yarn in its passage to the spool through a guide which is revolved through a circular path, but which remains substantially parallel with the spool axis, the pur pose being to avoid twisting and snarling of the yarn with a consequent unevenness in its tension; and to provide a mounting structure for the Spool and for the revolving guide in which the operating parts are completely enclosed so as to be removed from the View and from contact by the user. This last consideration is im portant because the winder is designed as a home appliance where it will ordinarily be used by unskilled persons.

The winding mechanism is one which lends itself to operation manually or by power. The

changes required for manufacture of the winder,-

either hand or power operated, are inconsequentiaL. The housing in which the operating parts are enclosed may be, of the same general contour.

in each case, although where power is employed the space within the housing should be somewhat enlarged for the accommodation of an electric motor. The present construction is advantageous, therefore, from a manufacturing standpoint, and also because it retains the same general appearance whether the device be hand or power operated.

Certain suggestive embodiments of our invention are set forth in the accompanying drawings wherein:

The yarn winder of this invention utilizes an upstanding housing in at one end of a sham bered base H over whose open bottom is afiixed a closure plate l2 having feet M to rest upon a table or other support. The closure plate is removably secured in place as by screws l5. Such a housing may be conveniently produced from plastic or other suitable material to enclose within its interior certain of the operating parts which desirably should be protected.

Upstanding from the closure plate is a mounting plate for a power unit such, for example, as is shown in Figs. 2 and 8. This unit comprises an electricmotor having a field 2 I, a rotor 25 fast on a shaft 26 which extends through an aperture in the mounting plate 22 to carry a pinion 2'! at or near its outer end, and a gear train 28, 29, and 30, the latter affixed to a horizontal spindle 3| which is journaled for rotation within a bushing 32 which is secured to the mounting plate near its upper end. The spindle 3| which is threaded engagesaxially with a spool 33 which extends outwardly through an aperture 34 in one wall of the housing Iii at an elevation well above the base II and in parallelism therewith. Near the outer end. of the spool is a narrow circumferential groove 35 for receiving and holding the end portion of the yarn y that is to be wound into a ball 36. g

The closure plate l2 terminates in an upwardly ofiset ledge 38 wherein is supported a fixed vertical bushing 40 through which is extended a shaft 4| mounting a pulley 42 fast at its lower end. A pinion 35 is carried fast near the upper end of the fixed bushing 40. A traversing arm l'l'having 2. depending rim 48 is mounted near the top of the shaft 4| to rotate therewith. The point at which the shaft .joins with the. arm is near one end of the latter. Upon the under side of the traversing arm within the confines of its depending rim 48' are mounted two meshing pin= ions 50 and 5!, the former being meshed with the shaft pinion 45. The pinion 5| is carried fast on a stub shaft 53 which up'st'ands from the traversing arm 4 near its end opposite that which is secured fast to the shaft 4|.

4 justing the pin At the top of the stub shaft is an eye 55 open to receive the yarn y that is to be wound into the ball 38 upon the spool 33. A boss 56 which is extended laterally from the base II is provided with a tapered socket having a vertical axis to receive the tapered lower end portion of an upstanding pin 51 (of plastic or the like) whose upper end is formed with an apertured head 58 constituting a guide. Through a lateral slit 59 the yarn may be inserted to lie within this headguide. Yarn passing through this guide and then through the eye 55 passes on up to the spool 33 where it is secured within the groove 35 before start of the winding operation. An endless belt 59 which passes around the pulley 42 extends around a pair of sheaves 60 at the base of the housing It) and thence upwardly and around a circumferential groove 5| in the spool 33, thereby to interconnect the pulley and traversing arm for concurrent operation. A control switch 63 mounted at the side of the housing is in circuit with the motor and a source of electrical energy (not shown) whereby operation of the winder may be started or stopped at will.

In operation, the motor drives the spool and with it the traversing arm which rotates with the shaft 4|. The eye 55 which is mounted near the free end of the arm describes a wide circle, but in so doing remains in a fixed position which desirably is one which parallels the spool axis. Because of the gear connection which the eye maintains with the stationary pinion 45, the eye position is unchanged while rotation of the traversing arm proceeds. Yarn which passes throughthe guide 58 and then through the eye 55 is accordingly shifted back and forth lengthwise of the revolving spool to which the leading end of the yarn is connected. As the operation proceeds the yarn thus drawn upon the spool is wound into a ball, the windings being spaced according to a definite pattern and with an even tension. This tension may be controlled by ad- 51 to a desired rotative position thereby varying the friction to which the yarn is subjected in its movement through the guide 58.

The semi-diagrammatic showings in Figs. 5 and 6 will assist in an understanding of a condition which is effectively met by the present winder. The spool is represented as rotatable in a counter-clockwise direction, and the traversing arm may be assumed to rotate in the same direction as viewed from above. Its center of rotation, as shown, is slightly off the longitudinal center of the spool toward its outer end where the end of the yarn is secured. At the commencement of operation the yarn is secured to the spool, and the yarn guiding eye is desirably positioned rotatively to lie opposite that same end of the spool. As herein indicated, the speed of rotation of the spool is slightly more than twice that of the traversing arm.

When rotation starts the yarn will pay out through the eye of the traversing arm with a variable speed which ranges upwardly from the peripheral speed of the spool as a minimum. The yarn advances upon the spool from one side only (see Fig. 5), its angle of approach varying according to the rotative position of the eye. When the spool has rotated through about 180 the traversing arm will have rotated through about 90, and the first layer of windings on the spool up to this point will be disposed substantially as shown in Fig. 6; with continued rotation of the spool through another 180 the initial yarn lay will appear about as shown in Fig. 2. There is a constant change in the angle of approach of the yarn as it leaves the eye to be wound upon the spool, first increasing progressively and then decreasing progressively as the traversing arm proceeds through the first and second quarters of its circular path of movement. The first layer of yarn windings will tend to shift toward the spool end whereon the lay was started, 1. e. where the yarn-is secured to the spool. The succeeding winding layers will build on the first layer, the latter determining the endwise position of the center of the ensuing ball. It is important, therefore, to locate the center of eye movement slightly toward the spool end where the approach angle of the yarn is the least, i. e. where the spacing of the first windings is the closest.

Other factors affecting winding of the yarn are the spool diameter and the relative speeds of rotation of the spool and the traversing arm. These may be varied within rather wide limits, the principal effect being to modify the shape of the yarn ball which is wound onto the spool. The second layer of windings, when laid over the first, will stabilize the position of the first layer, and will not build out endwise therebeyond. Succeeding layers of windings will build over one another, the result being a criss-crossing of the yarn windings in the formation of a ball having the general contour shown in Fig. 1. The completed ball will be self-sustaining, and permit release of the yarn from its interior without collapse of the ball structure until there is only a thin shell of two or three criss-crossed windings remaining. In this withdrawal of the yarn, no twisting or fouling will take place at any time, due to the regular pattern with which the windings were laid when the ball was made.

A similar construction of winder, but modified for hand operation, is illustrated in Figs. 7 and 8. Here the chamber of the housing 10 is somewhat less in size since there is no motor to be accommodated. Instead, there is journaled for rotation in a bearing H a spindle 12 which is screw threaded for coaxial connection with a spool 13 that extends through an aperture 14 in the housing to overlie the chambered base 15 from which the housing upstands. An endless belt 16 which is trained around a circumferential groove 11 in the spool extends downwardly therefrom and then around a pair of sheaves 18 to drive a pulley which is affixed to a vertical shaft 8| that is journaled for rotation in a bushing 82 having a fixed mounting in the upwardly ofiset ledge 83 of a closure plate 84 that is affixed to the base upon its open under side. To the end of the spool spindle 12 which lies exteriorly of the housing is aflixed a crank arm 86 with a handle 8! at its free end. By this means we provide for manual rotation of the spool and of the vertical shaft 8| as well.

A pinion 88 is carried fast at the upper end of the bushing 82 in mesh with a pinion 89 that is mounted on the under side of a traversing arm 90 which, near one end, is affixed to the shaft 8| to rotate therewith. A third pinion 9|, in mesh with the intermediate pinion 89, is carried by a stub shaft 92 extending upwardly through the traversing arm to support at its upper end an eye 93 through which is threaded the yarn 1/ to be wound on the spool where it is secured in a groove 94 near its outer end. A guide 95 in the form of a slitted eye at the top of a pin 96 upstands from a socketed boss 91 at the side of the base I5 oppositely of the shaft 8| to receive the yarn en route to the eye 93 and thence to the ate-abs? spool. As shown in Fig. '7, the'spbol has completed threerevolutions following commencement of the winding operation, the traversing arm having rotated one and a half times to produce three endwise lays of the yarn.

Theconstruction herein disclosed in slightly different forms is advantageous in respect of such features as simplicity and compactness. The deviceis also li ht in weight, and so maybe readily moved about or placed away, as desired. Its operating parts are enclosed within the housing so as to be completely protected, and also to safeguard the user whose fingers might otherwise come in contact with the moving parts.
