JACK OR DRESSER SPOOLING MACHINE..

' ments in Jack or Dresser Spooling Machines,

of which the following is a specification, reference being had therein to the accompanying drawings.

Figure 1 is a front elevation of a jack or dresser spooling machine containing my invention. Fig. 2 is a vertical section thereof at line 2 2 of Fig. 1. Fig. 3 is an end view of the upper part of one lof the pair of side frames which support my new thread-guide. roll. Fig. 4 is a view partly in side elevation and partly in lengthwise section, showing my new thread-guide 4roll. Fig. .5 is a cross-section-of said roll at line 5 5 of Fig. 4. Fig. 6 is a top plan view of a part of the jackspooling machine shown in Fig. 1. Fig. 7 is a partial end view of the same. Fig. 8 is a view partly in section at line 8 8 of Fig. 7 and partly in elevation and shows mechanism for reciprocating the traverse-bars.

The object of my invention is to obtain cross-sectional evenness in dresser-spooled thread or yarn; and my invention consists in the hereinafter-described novel .combination of arts necessary for obtaining this object.

n .the drawings illustrating the principle of my invention and the best mode known to me of applying the same, A is the main frame of a so-called jack or dresser spooling machine, and A is the creel-frame, in which thread-delivering bobbins a are rotatably mounted to deliver each its thread or yarn :I: to the rotary jack or dresser Aspool B, journaled in frame A and parallel with the subjacent contacting drum B. In its course from a bobbin to the dresser-spool on which it is wound each thread irstpasses over or through some kind of su porting contrivance extending crosswise of t e machine at the upper ends of the side frames a'. Each thread then passes downwardly in front of the colorcards aZ (which afford a suitable background for the threads, so that the operator in front of the`machine may readily see and detect defects in the descending threads and know when to stop the machine to correct defects) and thence through eyes asin the transverse traverse-bar a, the endwise movement of which 'prevents the threads from wearing grooves in the delivery-roll 0,5 and so maintains the delivery-rollsurface in a smooth condition. The threads severally make one turn around the delivery-roll and are then severally carried through eyes a in the transverse traverse-bar a?, adjacent .to thespool and drum, th'e endwise movement of the bar a7 serving to `position each thread with res ect of the `s ool in suchwise that each tliread is woun superimposedly on the spool without becoming mterwound with its neighboring thread. Heretofore saidithread-supporting contrivance has consistedbf a bar having depending from its under side a row of metal guide-eyes. Serious objections eX- ist to the use-of the bar and eyes, and they .have existed for manyyears, both abroad and in the United States.

First, when dresser-roll B is rotating and drawing off the separate threads' from the several bobbins in the creel the draft of the many threads on the eyes s rings the bar downwardly between its en s, so that the bar takes the concavo-convex shape shown by dotted lines in Fig. V9, causing some of the threads to slack more than others 'and pre-- venting uniform tension between the thread- .support and the delivery-roll a5. Whenever the machineis stopped, (as it must be at frequent intervals,) .the bar s rings upwardly. When the machine' is started), the bar is again arched. The consequences are that at each bending of the bar unequal tension is brought on the threads which pass downwardly to the eyes asof the traverse-bar a# and to the delivery-roll a5, resulting in unequal cross-sec- Patentet Jupe 5, 1906.

tional condition ofthe yarns or threads wound upon the dresser-roll. The necessarily frequent Stoppings and startings of the machine increase this defect of unequal cross-sectional condition (or unevenness) of thle yarns or threads wound upon the dresserro s. Y

Secondly, the lateral movements of the several yarns orV threads imparted by the traverse-bar a4, combined with their lengthwise movement, causes the threads to cut narrow slits or thread-passages' in the supporting portions of the metal eyes, the walls of these slits roughening the individual threads (more in some places than in others, according to the condition of the constituent IOO thread-forming parts) and producing Weakened or other imperfect spots or roughemng up of fibers and so requiring a stoppage of the machine and manual removal from individual IlO threads of semidetached vfibers thereof, the

have been generally unduly hard-that is,

wound too, com actly. A softer spool'H has been sought, ut hasnot been obtainable.

Io -To overcome the foregoing-,objections and obtain a softer spool, I have substituted for /the old bar and stationary eyes, Fig'. 9, a rigid 'freely-rotatable transverse thread-supporting roller D, having for each thread a separate #1.5 circumferential groove d, the bottom of which is concave and much wider than the diameter of the thread, as shown at d. By this construction` each thread is given a freelymoving support at the point from which it zo descends to the traverse-bar a4, and each thread is moved transversely across the concave bottom of the groove by the movements of the traverse-bar a, thus minimizing frictional restraint to the passage of the thread z and also causing the lateral and lengthwisf'ejl movements of each .thread .to wear the con!l cave bottoms of the grooves smooth and keep them so, whereby the moving yarns are not abraded by contact with roughened or slit- 3o like parts of the support. The peripheral ribs'dz, which separate the grooves, keep the threads a art one from the other, and the rigidity o the roller between its ends prevents variation in tension heretofore dueto said arching of the old eye-board. By my invention softer spools are obtained, the individual threads are kept in better condition,` z

uniformity of all the' threads on a spool is ini creased, and a greater number of spools can d4L at the upper ends of the side frames a Roller 4 5' D is'rotated by the frlctional engagement of the threads therewith.' The construction and operationof the rest of the machine will be readily understood by all skilled in the .art without further description. The traversebars lare reciprocated endwse byl old and well-known mechanism, (marked G.)

What I claim is-l In a jack or dresser spooling machine, the combination of a freely-rotatable, grooved roller which su ports the threads between the bobbins an the thread-delivery roll; a transverse, eyed traverse-bar; a delivery-roll said traverse-bar being" between said rooved roller and the delivery-roll; a s ool an drum; the thread-supporting roller eing rigid and v having alternating circumferential peripheral vribs 'and grooves, a groove for a bobbin'fand for a corresponding eye of the traverse-bar, and the bottoms of the grooves being concave and wider than the diameter lof the thread passing over it.

In testimony whereof I affix my signature in vpresence of two witnesses. Y.
