3 WINDING APPARATUS.

Application filed June 29, 1903. Serial 1%- 163,483.

To all whom, it may concern.-

Be it known that 1, CHARLES W. HUBBARD, of Boston, county of Suffolk, State of Massachusetts, have invented an lmprovement in Winding Apparatus, of which the following description, in connection with the accompanylng drawlngs, 1s a speclficatlon, like letters. on the drawings representing like parts.

My invention is an improvement in winding mechanism, and in the form'herein shown and described might be termed a diskspinmug device, one of my leading objects being to. provide means which will enable me readily to handle large masses of yarn or material, thereby greatly facilitating the subsequent handling and use of the yarn and economizing in time, labor, and otherexpense at all points where the yarn has to be handled.

To make my object clearly understood, it

-'may be well to direct attention to the great labor, delay, and expense ordinarily attending certain steps in 'the manufacture of textiles .as, for instance, on the present roving-frames the bobbins carry about two pounds 0f yarnand have to'be changed every halfrhour, whereas it is my ObJBCi) to make it feasible to usea thread mass of, say, thirty pounds, which will last about seven hours, and so on the spinning-frame where now a two-pound ro've-bobbin is used I substitute at least thirty pounds, lasting four days, and likewise .instead of the" customary small spinningbobbin (taking about one-third pound-of, yarn as it comes from the frame) I' will substitute; at least ten pounds, thereby requiring dofiing only one thirtieth as often as before. This great, saving of labor, expense, and time is eifected by providing compact and preferably self-sustaining thread masses oflarge' size,from which the thread unwinds in transverse layers from one end only,-said thread masses being preferably from three to five feet, less or more,

in length, or, if desired, having the same capacity by reason of ncreased diameter. 1 ac- I complish this in the preferred embodiment of my-invention herein set forth, in which I have chosen to illustrate the same in connection with spinning by means of a revolving flier within which'the thread mass rotates, said thread mass having superimposed thereon cooperating members which. cause the thread to be, laid in eccentric loops or paths'differentiated from each other by an increment or decrement sufficient topermit them to lie sub stantially flat, the layers thereof building up in succession with such compactness as may Specification of Letters Yatent.

be desired. By thus having the loops of thread laid in an eccentric'path they overlap cachet-her, so as to give the entire thread mass a compact, stable, and {permanent structure.

Further details of my invention will be pointed out in the course of the following description, reference being had to-the accompanying drawings, in which I have illustrated some of many possible embodiments of my invention. 1 t

In the'drawings, Figure 1 represents in vertical transverse sectiona portlon of aspinnmgframe with my invention applied thereto. Fig.

2 is a top plan view thereof. Fig. 3 is atop "plan view of the thread mass, or rather may be considered a d iagrammatlc view illustrating v the-system or order of winding.- 'Fig. 4 is a fragmentarycross-sectional view to show.in

better detail the thread-guide. Fig. 5 is a r central vertical section of another form of apparatus. Fig. 6 is a top plan view thereof,

details to be"ieferred to.

It will be understood that I have merely A undertaken to show sufficient details of a usual spinning-frame toenable my invention as applied thereto to be readily understood.

" Mounted on a suitablebeam a in a journal-' bearing'a is a flier. a having a hollow shaft a depending therefrom and provided with a belt-pulley'dT" Within this hollow shaft a is a second hollow shaft at, secured in any suitable ,manner, as'b'y threads at, at itsupper end to a support or plate a by means of a bushing a secured to said plate, said hollow shaft a carrying a gear a at its lower endin mesh with a pinion a", journaled in a pulley a, and also in mesh with a gear a, secured to the pulley a, already mentioned. This gearing is housed for convenience in the hollow belt-pulley a. The plate a is provided on its upper side with a frictional surface a), of felt or other proper substance, for starting the thread mass m upon. Resting on the with, said spindle being mounted in the sleeve or hollow shaft (5 and secured to the lower belt-pulley a. Said disk a has a radial slot a grooved to receive a thread-guide a 'through which the thread 25 passes.

Resting loosely above the disk a is a throw-plate or cam-plate a mounted'on the arms a of the flier and provided with a cam-shape'dopening' (4 (shown clearly in Fig. 2) for permitting the thread to follow the movements freey of Figs. 7 and 8 aresectional this'result to the best advantage.

In the foregoing description of the mechanism I have described in detail the-form of device which I prefer to employ when operating in connection with spinning; but it will be understood that I am not limited thereto, as many changes in form and arrangement maybe resorted to without departing from my invention.

' In operation the yarn Z passes down from the usual drawing-rolls through a guide-hole k to the thread-guide a and is caused thereby to follow the contour of the heart-shaped cam while being laid on the thread mass while reciprocating in the slot a in the disk a? The degreeof twist and the rapidity of winding del 'pend upon the relative speed at which the pulleys a" and a are rotated. To make this clear, let us suppose that the pulley a is stationary and the pulley a rotary. The rotary movement ot'said pulley a is imparted directly to the spindle (Rand therefore to the thread-laying member (1 This rotary movement of the pulley a also carries the gear at around the gear 4-,wh1ch We have assumed is stationary.

,Since the gears a and a have a dilferent number of teeth, it will follow that such r0 tation of the pulley a will cause the gear co to either fall behind or advance slightly ahead of a. according to the relative number of teeth in said gears. ihe gear a", it

will be remembered, is fast to the shaft a If in-.

and operates the thread-support a stead of the pulley a being stationary said pulley is revolved either in the same direc.

tion as the pulley a l, but at a'difi'erent speed or in the opposite direction, it will follow that the cam-plate a and the disk a will be rotated at different relative speeds. In any event, however, the thread-support d is caused to either fall slightly behind or advance slightly ahead of the cam-plate (0 because of the construction and arrangement of gears a n" a. Any suitable means may be employed for driving the pulleys a and at so that the relative speed at which said pulleys are driven may be governed as desired. By means of this construction and this form of gearing I can determine with the utmost nicety the laying of the loops or successive strands of thread or yarn.

In practice I preferto rotate both the pulleys a. and fa in the, same direction, but at different speeds, although it is within my invention to rotate them in either direction with any relative speed according to the results desired.

As shown in Figs. 1 to 4, the thread mass rotates. (for the purpose of getting the twist desired,) it being necessary so far as the mere winding is concerned, however, only that there shall be proper relative movement between the thread mass and the cam-plate and slotted disk, the cam-plate constituting a path-controller for the thread and the disk a or cam-plate b and cooperating rotator or depending flier 6 move, the former havinga heart-shaped cam b and-being retained by brackets 6", similar brackets 6 holding the flier. Said cam-plate and flier are provided with teeth in mesh with gears b b, fastened on a shaft 1), driven by a belt 6 one of said gears having a different numberof teeth from the other, so as to give a corresponding increment or decrement of movement of the thread mass with relation to the path-controller 7) for causing the successive loops of thread to be laid adjacent but not directly on top of each other, as already explained. A thread-guide or button 6 travels in the slot 6 having guide-ribs b at its opposite sides fittinggrooves I), formed in the windingplate said button at its'inner end having a thread-passage I) and at its outer end having a stud or pin 6, traveling in a groove 6" whereby it is reciprocated as required. Th thread mass is built upon a support If, mounted to turn on a post 6" and. normally held upwardly by any suitable means, as by weighted cords 6 passing over pulleys I), the support I) being caused to move with the rotator orfflier b 'by engaging vertical ribs or arms 6 extending longitudinally theueof. As herein shown, I provide three distinct movements in Fig. 1-the flier a and camplate at havingone speed of rotation from the belt-pulley a, and the supporting-plate a and 'presserplate or winder 10 havingitwo other movements, respectively provided, by the gear a and the pulley (13 while in Fig. 5 the same relative three movements are provided by having the rotator or flier 71 move at a different speed of rotation from that of the cam-plate orpath-controller Z), the winding plate or presser being stationary.

The relative speeds ot the thread mass and the presser-plate determine the speed of winding, and the relative movement between the cam-plate and the presser-plate determines c the progressive laying of the loops, while in part rotates at a constant speed when wind? ing. or, in other words, there is always a constant ratio between the speed of the winding member and that of the thread mass, as distinguished from a variable ratio. It will be understood, of course, that the speed of the various parts may be changed for either fast or slow winding and to give more or less twist to the threads; but the relative speed of the winding member and the thread mass when the pulleys are rota ting in the same direction is a constant quantity irrespective of the variations in the speed of either of said parts, this resulting from the construction and operation of the gears a a, and a, as willbe obvious.

4 As the-disk a), Fig. 1, moves around on the upper endtof the thread mass or inFig'. 5 as thethread mass moves around beneath the plate I) the thread is pulled down witha hard pressure and with 'unvarying precision, due to the pressure of thedisk orplate and thread guide as the thread passes from the lower end or edge of said guide, and as the disk orpla'te bears constantly on the thread mass there is no chance for the strands to'change position when once'laid. v

My invention has a wide field of usefulness and, as already intimated, I do not intend to restrict the same in all my claims to spinning, inasmuch as simply by omitting the twisting or spinning feature it is of great advantage in winding generally, or wherever it is desired to prepare a wound thread mass, as explained further in myconcurrent application, Serial No. 163,619, where I have shown another embodiment of my present invention. 1 i

I As the traverse-is simply along 'a'radial line, such as the slot a or 6 instead of being lengthwise of the spindle, it follows th'atithere' is practically very little limit to the length of the thread mass being wound, and instead of being limited to a few pounds Weight it may readily be ofsuch large size as may be desired.

The heart-shaped loops, as shown inFig. 3, are preferred because I have found that by this means I am enabled to, pack the thread mass compactly and satisfactorily, bringing the longer curvedsides of each loopapproxt mately parallel to the corresponding portions ofthe preceding loops.

' As the thread mass makes a complete rota:

tion, thereby permitting the laying of approximately one loop, the path-controller or cam-plate has traveled slightly more than one rotation, (or slightly less, as the case may be,) the thread being thereby laid correspondingly ahead of its preceding'path', and this process continues as the thread massand cam continue to rotate, one loop being formed each time and laid progressively, each loop having a series of successive points at different radial I distances from the center of the axis and each layer, includingapluralityof loops, extending across the thread mass.

I prefer. to have the loops extend around the center or axis of the thread mass, as shown in Fig. 3, this serving to give the greatest stability and firmness of position;" but it will be understood that I do not limit myselfthereto,

and also it will be understood that by the term loop 1 mean a back-and-forth or out andreturn laying of the thread. I

My in vention provides a thread inass which affords a great advantage overt-the system heretofore employed in certain kinds of manufacture-as, for instance, in carpetmills,

where itis now customary to take the yarn from the spinning-frame in six-ounce bobbins and put it on ten-pound spools,-&c., instead of which the desired ten-pound mass of thread may beprovided directly by my machine, and therefore go from thespinning-frame directly to the loom without the delay and expense of reeling and spooling.

If the thread mass wound is very large, it is slipped otf from the spindle, together with the upper plates and supporting-plate, which retain it until otherwise disposed of'by. suitable means; but if it is not sufliciently large to require this it will not be necessary to disturb the base-plate.

1 I do not herein claim all-the features of the invention shown, as some of them are also shown and claimed 1n my concurrent application aforesaid, and also it will be noted that I claim herein generically various of thefea- I tures of invention which are common to the three mechanical embodiments contained in this and the aforesaid concurrent application..
