SPINDLE FOR SPINNING AND '.I.`WISTING v l A v FRAMES Thomas Harris, Warwick Neck, R. I. Application Mayo, `1950, Serial No. 160,472

This invention relates to a spindle of the type used in the textile industry in a spinning frame ora twisting frame.

Spindles are usually Inounted'upon a rail and driven by a tape or belt.A Yarn packagesarey mounted on the upper blade portion of the spincile. I n ring spinning or twisting, the spindle must Ibe in proper alignment with the ring. Heretofore, it has been customary in setting the spindle inthe box rail to mount the base in the rail in sucha position that it was centered with refer# ence to the ring when closest to the rail. Then Vide armean's for centering the upper part of the spindle blade in the ring in its position furthest fromth e box rail by shifting the relative position of the lower bearing in which the blade rotates with reference to the base.

Another object of this invention is to provide anar-rangement so that the base has two parts surrounding the lower bearing and these two parts through eccentric relationships may be adjusted for varying the position of the lower bearing of the spindle to provide any desired position.

Another object of the invention is to eliminate thefnecessity of the use of shims to change the position of the axis of the base with reference to the rail in which it is mounted but rather change the lower bearing for the blade with reference to the upper bearing in the upper portion of the base.

With these land other objects in view, the invention consists of certain novel features of construction, as will be more fully described, and particularly pointed out in the appended claims.

In proceeding with this invention, Ihave found a bore in the lowersection ofthe spindle base eccentrically to the axial. line through thebase and I have provided a sleeve which has an outer cylindrical surface rotatablein the section bore and a cup for mounting the bearing which is also eccentric with reference to this sleeve outer surface. The sleeve may be mounted in thefeccentrie bore of the lower section of the base so that as the section and sleeve are relatively rotated different positions may be had for the centerv of thelower blade bearing Awith reference to the bearing at theupper part of the base in which the blademay-fulcrurn. v

Withreferenceto the drawings, I0 designates the b ox rail .of alspinning or twisting frame in which the'spindle is mounted.V A ring for a trav# eler vis designated II in its lower position and II in its upper position with reference to the spindle assembly. This spindle assembly is designated generally I2 and is provided with a base designated I3 which comprises an upper section I4 having a flange I5 forming a shoulder beneath it to rest upon the upper surface ofthe rail I0 as the section I4 projects through the opening IIin this rail. A This section v fof jthe base is threaded as at I8 land is secured in proper position with relation to the opening I'I by a nutv'IS engaging a washer 20 between this nut'and the lower surface ofthe rail I0. Thev base also" comprises the lower section 2l whichhas internal threads 22 to engage the threads I8 and may be rotated on the section I4 through this threaded engagement therewith. This section is held in the desired rotative position by a nut 23 which secures it in such adjusted position as it may be moved to.

A ball bearing 24 is set in a cushion mounting such as rubber 25 in the upper part of the base section I4 and is held in place by a cap 26 having a flange 21 which is threaded to engage threads on OFFICE possible' position to either the outer surface of the upper end of the base section I4. This bearing 24 receives a spindle blade 3) which has a lower portion 3I extending into the base I3 through the upper section I4 and into the lower section 2I. The upper portion 32 of the blade extends through the ring for the traveler II, and carries the package, while a whirl 33 is provided on this assembly for rotation of the spindle andpackage carried thereon by means or a tape or belt.

The lower section 2| of the base has a circular bore 35 which is eccentrically located with reference to the axial line through the base sections I3 and I4 when assembled (see particularly Figs. 2 and 4). A sleeve 36 has a closure 3'I and is of an outer cylindrical size 39 to 'rit the bore 35 for rotation therein. This sleeve has a cire cular bore 38 which has its center eccentrically located with reference toits outer cylindrical surface 39. This bore 38 is of a size to receive a ball bearing 40 into which the lower end ofthe blade 3| is stepped. A set screw 4I is rotatably' located in a plug 32v extending through the-wall ofthe section M so as to engage a groove 43 inthe sleeve 36. This set screw 4I will prevent the relative rotation of the sleeve Wheninally adjusted in the sectionv 2I. Y

In use, the base will be located in the rail I0 so -that it will be 'as near center as possible to the ring II when in its lower position and the nut I9 will be set up to hold this base section in place. The ring will then be raised to its uppermost` position relative to the spindle, as shown in Il', and the nut 23 will'be loosened so that the section 2I may be relatively rotated upon section I4 and the set-screw 4I will'be loosened so that the sleeve 36 maybe relatively rotated on the section `2I. By means of the rotationv of both sectionjZ'I and the vsleeve 3S the bearing 40 withthe lower end of the spindle blade will be adjusted in such amount as is necessary, the amount possible being 4shown by thedouble lines between Figs. 7 anda so that the upper end of this spindle will run true with reference to the ring when in the position shown at II. Thisadjustment occurs by the rocking ofjthe spindle blade about the center 45 of the bearing 24 as a pivot (see lig.` 7). ment about this point 45fas-a fulcrum occurs by adjustment of pointlit` which represents the lower bearinguntil thespindle blade axis '41 assumes an alignment at'the center ofthe ring in the upper positions of the spindle. After this hasbeen obtained the nut 23 isscrewed down uponthe section'I to maintain it secure withv reference to thepreviously secured` section I4 of the basef'while the 'set screw 4i is tightened upto maintain the sleeve 36 in its Yadjusted position relative to the lower section 2| of the base. Thus the alignment of the bearings is secured without the necessity of shimsilocated between the shoulder I6 and the box rail as has heretofore been customary. l

The provision of the base in two sections I and 2I' also' provides a vconstruction `which will The move- 4 obtain all of the advantages of my copending application, Ser. No. 118,613, of which this is a continuation in part as well as to enable the advantages above set forth.
