Specification of Letters Patent.

Patented July 25, 1916.

Application filed January 8, 1916. Serial No. 70,899.

13, 1910, Serial No. 581,748, wherein are dis-v closed certain features in relation to `such spindles which are also preferably incorporated in the structure shown herein.

The present object is to further improve these spindles, securing a simple, substantiel and relatively `light construction, easy to manufacture and adapted to utilize the principle of balanced masses set forth in my said prior application, and especially to produce a spindle in vwhich the operation'of threading up can be, accomplished with rapidity. j

In the accompanying drawings: Figure 1 is a view, partly in side elevation and partly in longitudinal section, of the spindle, with its hauling-ofmechanism and flier, and the associated bobbin and bobbin spindle; Fig. 2 is a view', also partially in elevation and partially in longitudinal section, taken at a different angle from Fig. 1; and Fig. 3 is a cross-section onthe line III of Fig. 1.

- The body of the spindle is a substantially straight shaft l, which, as a matter of design, may vary in cross-sectional area and shape at different points in its length. Its separated portions 2 and 8, adjacent the ends are formed as journals to turn in the bearings 4. and 5, which are carried by thev fixed framework of the spinner, not shown. The end portion of the-shaft comprising the journal 2 is tubular'and aords an internal bearing for an independently driven yarntube 6, which projects beyond the bearing f1 and beyond the end of the spindle and is I. there provided with ay gear 7 whereby it is rotated independently `and at a speed differing from that of the spindle, which is driven by a pulley 8 mounted adjacent-the ournal 2. rlhe portion of the shaft constituting the other journal 3 is of largerl diameter than the -journal 2 and is enlarged outside the bearing 5 to form an end thrust shoulder 9 and a face plate or flangelO, to which latter the base of a can Hier is firmly bolted or otherwise secured.

- f Intermediate its journal portions and the supporting bearings, the shaft carries the hauling-off mechanism which comprises main and auxiliary capstans 12 and 13, each mounted to revolve on an axis intersecting and transverse to the aXis of the spindle. As in my prior application/aforesaid, the capstan members arel constructed so as to have equal portions of their mass disposed at opposite sides ofthe aXis of the spindle, whereby the benefits of high speed operation may be realized, as there fully explained. rl`he capstansA proper, however, andtheir counterbalancing elements are at opposite sides of the spindle body, that is to say, on opposite sides of the immediate supporting portionof the spindle, which is in line with the-journal portions instead of olf.

set therefrom as in my prior construction.

The capstan 12 is Xe'd on an axle 14 which is journaled in a transverse bearing bored in the spindle body and carries at its opposite end Ya bevel gear 15, which is dished or crowned in order that its teeth may mesh with the teethof a bevel pinion 16 on the inner end of the yarn-tube 6, the engage* ment of the toothed members being made possible by a clearance groove in the shaft at this point, as will be Vseen in F igfS. The counter-balance for the auxiliary capstan 13 comprises a cap-like washer 17 interposed between the nut 18 on the end of the capstan axle 19 and a boss 20 on the spindle, it beoil' masses is not essentialto the invention;

The sliver which enters through the tube 6, on the dot-and-dash line indicated, passes beyond this tube through a passage 21 in the interior of the shaft, the said passage bearing off oblquely or at a gentle curvature from a general longitudinal direction, in order to conduct the slivery in a. substantially straight-line path to a lateral, obliquelyfacing outlet 22, between the axes of the two capstans and substantially opposite the grooved periphery of the auxiliary capstan 13, to which the incoming stretch `of yarn directlyextends. Thence the yarn'is trained Vback to the main, or positively driven, capstan 12, and thence back and forth between the two for a suitable number of passes, according to the number of yarn grooves provided therein, after which it is trained over an external guide pulley 23, adjacent and at the inner side of the bearing 5,y and between the hauling-olf mechanism and the flier. This guide is counter-balanced like the capstan 13, having aV stern 24: which is inserted through a diametrical hole in the spindle and provided at the otherside thereof with a cap or washer 25 and nut 26. From the guide button23 the yarn passes through a transverse and straight passage 2f( extending the open end of the ier, and thence passes,

inward to the bobbin 30, the guides 28 and 29 on the iiier being` preferably in skewedv relation as shown in order tcsecure the advantages set forth in ymy prior application before mentioned. The bobbin it vwill be understood, is traversed by suitable mechanism, not necessary to illustrate, on the bobbinspindle 31, one end of which finds a terminal bearing at 32 in the endl face of theA flier spindle.

The mounting of the yarn tube 6 in the feeding-in end of the flier spindle, includes Va bushing or internalsleeve 33, which is threaded as shown at 311 to the Yinterior of the outer end of the tubular portion of the spindlebody, the outer end of this bushing having a flange 35 in abutting relation to the extremity of the spindle, and its inner end preventing outward axial movement of theV pinion 16 and therefore ofthe yarn tube.

It will be evident that the through passagevr27 together with the external location of the pulleys and the fact that there need befbut one direction-changing guide on the spindle between the hauling-off mechanism and the flier, greatly increase the ease and quickness with which the threading operation may be performed. In this connection it is to be observed that the course of the yarn from the inlet end of the yarn tube 6 to the lateral outlet 22 is substantially aV straight one, and that the capstans .are wholly exposed and devoid of adjacent obstacles to the` hand or yarn in threading, thesebeing matters of much practical importance to the operator, in respect to the time saved and the wear on the machine, by

the yarn, and the wear on the yarn by the machine.

What I claim as new is 1. A spindle of the character described, comprising a straight shaft constituting the spindle body, having separated journal portions, Capstans carried laterally by the straight shaft portion between the journal shaft to permit the Yyarn to pass to portions thereof, with their axes transverse to the axis of the shaft, a yarn inlet through one of the journal portions and a passage leading therefrom through the side of the the capstans.
