MACHlNE FOR WINDlNG QUILLS AND BOBBINS.

SPECIFICATION forming part of Letters PatentNo. 384,011, dated June 5, 1888.

Application filed August 8, 1887. Serial Iio. 246,393. (No model.)

To all whom it may concern.-

Be it known that I; JOHN E. A'rwoon, of Stonington, in the county of New London and State of Connecticut, have invented a new and useful Improvement in Machines for Winding Quills andBobbins, of which the following is a specification.

My invention relates, generally, to machines for winding quills and analogous bobbins with threads or filaments, and is more particularly intended for machines for winding shuttle In such machines it is necessary to provide, in addition to the spindle and flier for winding the quill, a traverse-guide for producing the traverse of the silk upon the quill, which is commonly built in conical form, and a stopmotion for arresting the rotary motion auto matically when the quill is filled with silk. In such machines there are commonly two rows of spindles and fliers, one upon each side of the machine, and the two rows are driven by bands from a common driving-shaft extending lengthwise of the machine midway between the rows of spindles.

The important objects of my invention have been to simplify the construction and consequent expense of the several parts of the ma chine, and to provide a machine which will produce comparatively excellent work, and yet which may be supplied at a small cost as compared with the majority of the quillingmachines for a similar purpose.

My machine possesses several features which I believe to be entire novelties in-the art. In a certain class of quillingmachines heretofore in use a rotary spindle has had a quill mounted upon it, and the silk or thread has been laid by a flier rotating around the quill, and the spindle has been traversed to and fro through the flier with a quill upon it.

According to my invention I employ hollow spindles, each of which terminates in a tubular flierthat is to say, a tube which is slotted lengthwise to its extremity-and the quill is thrust upon a suitable support presented downward within the end of the tubular flier, and by this support the quill is sup- I the tubular flier, and is locked to turn therewith, so as not to wear the thread. Awhirl is upon the spindle, and upon this whirl drives a constantly-running band, and whenever desired the whirl and the spindle are stopped by a stop-lever, which forces the whirl against a brake and holds it and the spindle stationary, while the band renders loosely around the whirl. Although this operation of the band and stop-motion does produce some wear of hands, it providesa stopmotion of extreme simplicity, and the advantages secured more than counterbalance the additional wear of the band.

In the machine each row of spindles is supported in a double girt comprising upper and lower rails secured together by struts between the spindles, so as to hold them at exact distances apart. The upper rail of the girt carries in it a bearing-bushing, in which the spindle is journaled, and the lower rail of the girt carries a thread-centeringdevice and oil-guard, which is concentric with the spindle,and which enters slightly within the spindle. The quill- 7 support has connected with it a verticallymovable rod, and the quill is raised as it is filled by contact with the silk upon it of the tubular flier, and as it is filled its verticallymovable stop-rod actuates a stop-lever, so as to bring it in contact with a lump or projection forming an uneven surface on the whirl, and as the whirl turns the lump or projection by cramping on the stop-lever swings the lever on its fulcrum, and thereby causes it to crowd the whirl against a brake-collar on the bearing-bushing, thus stopping the spindle until the full quill has been removed and a empty quill substituted.

The invention consists in novel combinao tions of parts, some of which are hereinabove described, and which arehereinafter set forth, and pointed out in the claims.

In the accompanying drawings, Figure l is a side view of a machine embodying my in- 5 vention, a portion only of the spindles in one row being shown. Fig. 2 is an end view of the machine. Fig. 3 is a transverse section of the machine between its ends. Fig. 4 is an elevation, upon a larger scale, of one spindle I00 and flier and its appurtenances and a transverse section of one of the double girts of the machine. Fig. 5 is an elevation of the parts shown in Fig. 4, but completely in vertical section; and Fig. 6 is a perspective view of the quill-holder, which holds the quill.

Similar letters of reference designate corresponding parts in all the figures.

A designates the end standards or frames of the machine, and between these extend girts B B B B The girt B is here represented as double, composed of upper and lower rails connected by struts or posts I), so as to hold them invariably at exact distances apart, for a purpose hereinafter described. In the girt B, at opposite sides of the machine, are rows of spindles 0, one row upon each side of the machine, and these spindles have whirls 0, around which pass driving-bands c. A separate driving-band for each spindle embraces its whirl c, and also embraces a driving drum or pulley, 0, upon the main shaft G and separate guide-pulleys 0 which are above the driving drum or pulley, and the bands 0 for driving the spindles are preferably arranged according to Letters Patent No. 296, 37 7 granted April 8, 1884, to John E. and Eugene Atwood.

Each spindle G terminates at its upper end in a tubular flier, 0*, which has a cylindrical exterior, and upon which slides freely a traverse guide or collar, 0 The tubular flier O" is slotted lengthwise, as shown at c, and the traverseguide G is correspondingly slotted at 0 and the traverse-guide is locked to turn with the flier by a pin, 0*, entering the slot 0 in the flier. I have here shown fast and loose pulleys O 0 upon one end of the shaft 0 and at the opposite end I have represented a pinion, 0 which engages a wheel, a", and through a pinion, 0 transmits motion to a wheel, 0 Connected with the wheel 0 so as to rotate as one therewith, is a cam, 0 which acts upon the end of the arm or lever 0 Upon opposite sides of the center of the machine are two rock-shafts d, which are connected together by arms d, having sectorgears which engage each other, as best shown in Fig. 2, and the two rock-shafts d also have "arms d which extend outward from each shaft, and are forked to embrace freely the tubular fliers O and to bear against the lower flanges of the traverse-guides There is a sufficient weight in the traverse-guides to produce their free descent when the arms d move downward, and the two arms themselves serve to move the guides upward, and consequently the two rock-shafts d and the cam c produce the traverse necessary in winding both rows of quills.

In the upper rail of the double girt B, at each side of the machine, are bearing-bushings D, which have at the top flanges, d resting against the rails of the girt, and in which the spindles 0 are journaled. The portion of the the bearing D. I have shown secured upon the lower portion of each bushing D, and adjacent to the whirl c, abrake-collar, D, which has a conical lower surface entering a conical recess in the top of the whirl c, for a purpose hereinafter described. In the lower rail of the double girt is represented a tubular threadcentering device or oil-guard, D

6 designates the quill, which is fitted upon a stem or quill holder or support, E, depending from a downwardly-turned rod, E, which is free to slide in a suitable guide, 6, and which has collars e 6 upon it for limiting its movement.

In Fig. 6 I have best shown the quill holder E. It has a spring-extension, s, which forms a yielding stem for entering the quill e. The holderE has in it a bore or socket, s, which receives the downwardly-turned end of the rod E, and, a hook, s, which,when the holder is turned, passes or hooks over the rod E. The silk or thread enters the lower end of the oil-guard or thread-centering device D passes upward through the hollow spindle O, is thence taken outward through the slots 0 c, and passes above the traverse-guide 0 through the slot 0,- inward to the quill 6, around which it is wound. The quill e remains stationary, and

by the rapid rotary motion of the spindle O and the flier 0* the thread is laid upon the quill e while resting in the slot 0 in the flier, and the top of the flier being cut obliquely, as is best shown in Fig. 4, so that one side of the slot 0 will form a shoulder, a, for carrying the thread around. It will be observed that as the quill increases in body by the winding the interior of the tubular flier O bears against or substantially upon the quill and gradually lifts the quill and the rod E, upon which it is fixed, and the rising movement of the rod E is utilized to stop the machine in a manner which I will now describe.

F designates a stop-lever, which, as here shown, is fulcrumed at f to the part forming the oilguard and thread-centering device D, and which is adapted by its upper end to bear against the lower side of the whirl c, and I have shown such lower side as oblique, or as having a lump or projection, 8, against which the lever F may come to a hearing.

In the lever F, I have represented a lifting projection or stud, f, with which the arm or coller e of the stop-rod E may come in contact. Ordinarily the weight of the upper part of the stop-lever F is so placed as to its fulcrum as to hold the lever out of contact with the lump or projection s on the whirl, but as the quill becomes nearly complete the rising movement of the rod E, acting through the tappet or collar 6 serves, through the stud or projection f, to raise the stop-lever F and move it inward or upward, so that the lump or projection on the whirl will in the revolution of the latter, strike the top of this lever,

and as soon as this occurs the whirl instantly carries the lever inward by friction and causes IlO it to block the whirl o upward firmly against the brake-collar D, thereby stopping the whirl and spindle and permitting the band cto continue to render around the stationary whirl until such time as the whirl is again released from the embrace of the stop-lever F.

It will be obvious thatin passing the threads to the machine it is of the utmost importance to have the spindles stop when the quills are full, with the slots 0 0 presented at the front, so that ready access may be had to them for threading the filaments. This may be secured by properly arranging the whirls c on the spindles, so that when their lumps or projection 8 have, by engaging the stop-levers F, effected the stopping of the whirls and spindles the slots 0? c in the tubular fliers 0* will be presented outward at the front. When the stop-lever F is pivoted behind the spindle, as in this example of my invention, the whirl is fixed on the spindle so thatits lump sis about diametrically opposite the slots 0 0 I have shown upon the girt B j aeks or fixed spindles g, on which are placed the spools g, from which the threads are severally taken, and adjacent to these jacks or spindles are brake-levers g, which bear upon the silk on h, and which have a tendency to drop backward when the thread breaks.

H designates a lever, which is fulcru med at h, and has an upwardly extending arm adapted to strike against the stoplever F when swung toward the right hand of Fig. 1. The lever H is so balanced by the weight 71, that the arm h normally remains horizontal; but

when by the parting or giving out of an end one of the fallers, 71, drops back upon the leverarm h", an upwardly-extending arm of the lever H is movedin the direction indicated by the arrow in Fig. 1, and by striking against the stop-lever moves the latter upward within range of the rotary whirl c.

It will be seen that my machine is of the simplest and most inexpensive construction possible, and that notwithstanding it possesses all the necessary requisites for good work.

The quill proper, 6, may be considered as the quill support for receiving the silk.
