wlNbiNe. APPARATUS.

Specification of Letters Patent.

Application filed January 30,1904. Serial No. 191,277.

.To all whom it may concern:

Beit known that I, CHARLES W. I-IUBBARD, a citizen of the United States, residing in Boston, in the county of Suffolk and State of Massachusetts, have invented an Improvement in Winding Apparatus, ofl which the following description', in connection with the accompanying drawings, is a specification, like letters on the drawings representing like parts.

My presentinvention is an improvement on the general form of apparatus shown and described in my application, Serial No. 163,483, filed June 29, 1903, the improvements relating more particularly to means for simplifying the apparatus so as vto wind or lay the thread or yarn with an even tension and also facilitate the convenience and speed of operation.

In building the thread mass by laying successive loops in the general 'arrangement as set forth more in detail in my aforesaid application it is obvious that if the thread-is delivered with constant speed to a uniformlymoving thread mass or winding apparatus the thread will be under greater tension when beinglaid adjacent the periphery of the thread mass than when beinglaid adjacent the center, as greater travel takes place at the periphery than at the center, and hence if no provision is made for either changing the relative speed of movement or the speed of delivery as the Winding approaches or recedes from the center of the thread mass there will be undue tension on the thread at the periphery and undue slackness at the center, thereby producing defective results, especially in the twisting, and accordingly,v I have devised means for avoiding the above objections and securing uniform tension at all times, and in connection therewith 1 provide means for avoiding' the necessity of weighting the thread mass in order to secure properly compact and regular winding, and also means permitting the quick threading and starting of a new thread in the apparatus upon the breaking or completion of winding of the previous thread. These and further features of the invention and various advantages thereof will be pointed out in the course of the following description, reference being had to the accompanying drawings, in which I have shown apreferred embodiment thereof, the invention being further defined in the appended claims, also forming a part of this specification.

Figure 1 is a central vertical sectional view of a suflicient portion of the apparatus to make the invention clearly understood. lFig. 2 isA a top plan view thereof, the thread-guide be-v ing in its outward position.y Fig. 3 is a bottom plan view of the thread laying or winding members removed'from the rest of the apparatus.

For enabling my invention to be fully under-` stood .I have shown the same as adaptedl both to wind and spin and for this purpose have shown means for producing the three relative movements necessary for accomplishing both of these resultse-viz., means for rotating' the thread mass, means for rotating the winding member with relation thereto, and means for moving a path-controller with relation to said winding member, and it will be understood that the relative movements of these parts may be varied according to the 4degree of twist or the compactnessof the thread massA disk a3, having a radial-slot at, in which trav-` els a th read-guide a5, said thread-guide having lateral rlbs whlch are received 1n grooves in the walls of the slot at. Beneath this plate or winding member is a path-controller or cam-plate a, having a heart-shaped cam for laying 'the thread inthe proper form of loops for compact winding, said winding means a3 a6 being held in proper position for relatively rotating on the ledge a7, projecting from the lower inner edge of the rotator-ange a2. These several parts are respectively rotated by hollow shafts as a9 al", journaled in the frame,

the shaft al being rotated by a gear al, whichhas mounted thereon, so as to turn about its own axis. a pinion am. This pinion is mount-` ed eccentrically to the axis of the gear al, as plainly seen in Fig. 1, and is capable of rotation about its own axis independently of the rotation of the gear am.

meshes with two gears al* and c on the shafts a9 and a8, respectively, said gears a and L15 having a different number of teeth.

The shaft as has fast thereto and is driven Patented Aug. 1, 1905.

While the general results may- Said gear 6213.

by a gear (i12. The gears am and al may be of the same or of different sizes and may be rotated at different relative speeds by any suitable means, as, for example, by means of gears e als, fast on shafts al @20, respectively, which shafts .are driven by any suitable driving mechanism. (Not shown.) The shaft t8 carries at its upper end a rotator or iier a. The shaft a carries at its upper end an arm a2?, engaging the path-controller a at @22, and the shaft am engages the winding member a3 at @23. The gears am and el are preferably rotated in the same direction, but at different speeds, and in such case the winding member a and the flier or rotator e will rotate in the same direction, but at different speeds.

Since the gear el, which carries the pinion C013, is rotating at a different speed from the gear am and since the gear am rotates with the gear am, it will follow that the gear am will be turned about its axis during its movement around the axis of the gear al, and as the gears tu and am have a different number of teeth the shaft a" will gradually either fall behind or advance ahead of the shaft a, such ,movement being just sufficient to give the necessary1 increment or decrement to the successive loops of threads.

The means for providing uniform tension of thread-delivery, already alluded to, may be provided in various ways; but 'for compactness and simplicity of arrangement, as Well as to permit the thread-delivery to take place at the bottom of the thread mass, I have arranged an arm a2", projecting from a hub 025, mounted to slide longitudinally on the shaft am and caused to rise and fall in unison with the movement of the path-controller t6 by means of a cam a2, fast on the upper end of the path-controller shaft a.

' Since the shafts a and am have a different speed relative to each other, it will be obvious that the hub L25 will be gradually raised by the cam a2 until the limit of its upward movement is reached, and then said hub will descend by its own weight, thus giving` an up-and-down movement to the arm @24. This up-and-down movement corresponds exactly with the inand-out movement of the thread-guide, and thus the thread is maintained under an even tension.

The thread t passes up through the hollow shaft am and out through an opening t2? there-` in, thence underthe free end of the arm am, as indicated at @28, to the thread-guide ab, by which it is laid on the under side of the thread mass/the latter being caused thereby to gradually rise as the thread mass builds up.

In order to cause the thread mass to turn with the rotator, suitable friction devices are provided, being .herein shown as curved fins oi"inwardly-projecting wings e2, secured to the inner wall of the housing e2. A shoulder as is provided for receiving an `inclosing can am, if desired, for directing and receiving the upwardly-moving thread mass.

By having the thread delivered at the under side of the. thread mass and providing the frictional devices and the various constructional details explained I am enabled to wind a compact cylindrical thread mass without superimposed weights or other retaining and compressingdevices. For further facilitating this object, as well as securing other advantages, I have provided the following means for yieldingly retaining the thread-guide ai in position. As herein illustrated,said threadguide has a stud or depending lip uf, which is adapted to engage the edge ofthe heart-shaped opening ai of the path-controller a, and said stud is maintained in engagement with the edge 0f said heart-shaped opening by a spring ai, which occupies a groove am" in the winding member a3 and abuts at one end against one end of said groove and at the other end engages the threadeguide ai. For retaining the spring in position I provide a tube r/ff, which is secured to the thread-guide and receives one end of said spring` as best shown in Fig. l. By reason of this construction a new thread or broken thread may instantly be started on the under side of the thread mass, all that the operator is required to do being simply to shove the thread-guide bach to the center and then insert the thread end upwardly through 4the thread-opening in said guide and then let go of the thread-guide, whereupon the upwardly-projecting end of the thread will be instantly caught and held frictionally between the bottom of the thread mass and the top of the winding member a3.

Besides permitting the threading of the machine at the bottom of the thread mass the spring arrangement above explained permits` a simple cam-plate or path-controller ft, and also avoids the friction and possible catching, &e., of the thread-guide as constructed in my before-mentioned copending applications. ln order to further facilitate the threadingol' the apparatus, the hollow shaft am is provided with a directing-surface uf" at its upper end for directing the thread end outwardly through the opening a, said surface being herein shown as provided at the lower end of a plugl ai, closing the upper end of the shaft.

In practice the thread mass is permitted to build up to a considerable length and is then separated into such sizes of thread mass as desired simply by inserting a suitable flat knife, so as to pry otll or sever the upper portion of the thread mass from the lower portion, and the winding then continues, constantly pushing up the superimposed portion of the thread mass. The resistance of the curved wings ft2 takes the place of a weight and effects a firm compact winding, while at the same time it compels the thread mass to rotate properly.

rThe speed of winding depends upon the relative rotation between the winding menn-I ber or plate a3 and the thread mass, and the amount of twist depends upon the number of revolutions of the winding member during the winding of a given length of thread, -so that in order to increase the amount of twist it is necessary to bring the speeds ofrotation of the winding member and the thread mass more nearly in unison, there being nothing but twist and no winding when both rotate together and the least twist when the winding member approaches a stationary conthe successive'loops, the tension-evener rises and falls,permitting the thread to be delivered faster to the thread mass as the thread-guide moves outward and slower as the thread-guide moves inward, it Abeing understood that the thread is required tov pass with uniform speed along the hollow shaft am, (or such other means as may-be provided for conveying or delivering the thread,) the movement between that point' and the th read mass varying as the speed of the thread consumption varies, so that the thread will vescape from saidv hollow shaft with the same speed irrespective -of whether it is being laid nearthe center or near the circumference of the thread, and in order to have the winding means and thread mass rotate constantly with the same relative speed I have interposed the slacliening and tightening device which takes up the thread as it is being deposited toward the center and gives out or releases the thread as the latter is being deposited toward the circumference.

If the thread breaks, the operator simply takes hold of the under side of the threadguide and pushes the same inwardly to the center beneath the hollow center of the thread mass, being14 thereby enabled to insert the thread quickly up through the hole in the thread-guide, and upon releasing the latter the projecting upper end of the thread is immediately caught and held between the thread mass and plate or winding member a3. while the winding continues.

If the thread escapes from thedeliveryshaft ci", it is readily inserted because of the directing shoulder orsurface a3?.

By reason of the epicyclic gearing. and vari- `able driving thereofv all the desired changes.

in relative motions above mentioned may be readily secured. i
