""5-Claims.

'I'hisinvention relates to spindles used in spinning, twistihgforwir'fding "operations; When '"such-"spindles: are in use. and particularly when used ="with "'rayon or other synthetic" fibers, it is desirable that the spool on thespindle beso 'posi-1 tioned vertically that the "lower "limit of yarn traversewill be in correctvertical relationto the top surface of the lower *he'adof the sp'ool. "If tlie spoolisnot so positioned,the'yarn'will be "wound irregularlyat the lower end'of thetrav'erse' "and will frequently "bind 'or break while being unwound from the spool.

*Itis the general ob'ject'o'f my invention to pro- *v'icleimproved spool-adjListing means "by "which the spool maybe accurately positionedvertically- A"fu'rther'-'ob'ject 'is to provide improved spoolsupportingmeans which can be adjusted=withoutreniovi'ng'any part of the spindle from' opera- "tive position, and. even"'without "stopping the frame.

A further object is toprovide a construction b'y'which theamount-ofvertical spool adjustment "can beaccurately' predetermined.

Preferred forrns 'ofmy' invention are shown in the drawings; in which -"Fig. "1 is 'a sectional s'ide elevation-of "a'twi'ster spindle and associatedparts, with my invention embodiwtherein;

'belt drivenwhirl' is'fiXed on the blade I! above its supporting bearing and rotates outside of'the upper part of theb'ase and'bolst'er. The usual doffer-guardzl prevents upward displace- "inent of the'spi-ndle, and the-usual brake lever 23 and brake 2.4 provides Jmeans for stopping the spindle without stopping the remaining spindles on the frame. The'lower end 25 of the blade ll has a 'cylindrical 'be'aring inthe-lo'wer end of the 'bolster l4 but has no step' bearingthereinr The"usualtravelerT rotates on atwister-ring R carried by the vertically reciprocated ring rail 30. The yarn Yis guidedbythe traveler'T to a spooks-mounted? on thdbla-de -l'l'an'd on which "Fig.4 isa'sectional side elevation ofsaid'mem- Fig. 5 is a plan view of "an adjusting ring which coacts with said spool-supporting member;

Fig. 6 is "a sectional "side elevation thereof, taken along-the line6 6' in'Fig. 5;

'Figx'l is'asecti'onal side elevation, showing my *invention applied to a somewhatdifierent'type 1 of spindle;

Fig. '8 isa "side elevation of a portion of a spindle;partly'in section and showing a modified construction; and

Fig. 9 is a view similar to Fig. 8 but showing a further modification.

Referring to Figs. 1 to 6, I have shown my invention embodied in a spindle comprising a base l0 secured in a fixed frame member H by a clamping nut 12. A bolster I4 is mounted in an upward extension of the base 56 and is held in fixed vertical position by coacting shoulders on the bolster and base, as indicated at I5.

A spindle blade I! is mounted in the bolster I4 theyarn is wound.

My 'present invention relates particularly to improved' mea'ns for'vertically adjusting the spool '8 so that the upper surface-3| of thelower head "32of-the spoolwill bet in correct 'vertical relationship withtthe -yarn-guiding portion of the traveler T,when -the-'ring-rail is at the bottom of its traverse.

"For this purpose, I provide a spool-supporting cap'MI loosely mounted 'on a cylindrical upper portion ofthe whirl 28. Driving lugs 42 are form'e'd'on the top of the cap and engage radially disposed slots in the lower surface ofthe spool Sta form the-usual spool-driving connec- -Thelower-edge of'the cap 40 is formed witha plurality of segmental helical surfaces 43 on which downwardly projecting teeth M are provided. 'The number of these segmental surfaces maybe varied but three such surfaces are shown in the drawings. 7

A ring '50 is fixed on the lowerpart of the cylindrical portion 4l -of the whirl 20 and is provided'with segmental surfaces 5 I havingu pwardly projecting teeth 52, as shown in Figs. 2 and 6. The surfaces 5| and teeth 52 coact with the surfaces 43' and teeth 44 to vertically position the a Binding screws 54 are providedin the' cap'flfl and may be used if desired to retain a'n'adjusted angular relation between the cap 40 and whirl 20. Under ordinary conditions, however, these parts will retain their adjusted position, even if the binding screws 54 are not used.

The method of operation and advantages of my improved construction will be readily apparent. By lifting the cap 40 to clear the teeth 52 of the of the cap 13.

moving the spindle blade or any other part. of

the spindle from the base l0. Furthermore, by applying the brake 24, the spindle may be held from rotation during adjustment and the adjustment may be made without stopping the other spindles on the frame. I I

In this manner, vertical adjustment of each spool may be quickly and accurately made and positively retained, and removal of partsv or interruption of machine production is entirely avoided.

' .In Fig. 7 I have shown my invention embodied in'a spindle of a somewhat difierent type, in

which a blade 68 is rotatable in an upper bearing 6| and lower bearing 62 in a bolster 63, and in which also the vertical relation of the blade 68 to the bolster 63 is determined by a step bearing 64. The vertical position of the bolster in the base is also determined by a step bearing 65. A whirl 61 is fixed to the blade 60, as previously described. The spool-supporting cap .68 and toothed ring 69 are of the construction shown in Figs. 3 to 6 and operate inprecisely the same way in providing vertical adjustment for a spool mounted on the spool-supporting member or cap 68.

In Fig. 8 I have shown a modified construction, in which a whirl 10 is fixed on a spindle blade H and is provided with a threaded portion 12. A spool-supporting cap l3is provided with an internally threaded portion 14 engaged with the threaded portion 12 to determine the height Driving lugs15 are formed on the top surface of the cap 13 as previously described, and one or more clamping screws 16 are provided to maintain the parts in an adjusted angular relation. By turning the cap 13 on the threaded portion 12 of the whirl 10, the cap may be raised or lowered to any desired extent, and the adjustment can be retained by tightening the screws 16.

This method of adjustment does not provide the positive lock of the toothed construction previously described, but on the other hand it permits finer adjustment than is possible with 'lugs 84 are formed on the upper face of the cylindrical portion 83, so that the spool drive is not transmitted through circumferentially adjustable parts.

A spool-supporting ring 86 is threaded on the part 82 of the whirl 80 and is rotatable about the cylindrical portion 83 of said whirl. A spool is supported on the upper surface 81 of the ring 86, and the ring may be held in angularly adjusted position by one or more screws 88.

This construction preserves the fineness of adjustment found also in the construction shown in Fig. 8, but the ring 86 merely supports the spool and has no spool-driving function, being in this respect an improvement over the construction shown in Fig. 8.

Both of the modified structures shown in Figs. .8 and 9 may be adjusted without removing the spool or any part of the spindle from the frame,

and may also be adjusted if desired without stopping the rotation of other spindles in the frame.

It will be understood that the word spool as used herein includes bobbins also.

Having thus described my invention and the advantages thereof, I do not wish to be limited to the details herein disclosed, otherwise than as set forth in the claims, but what I claim is:

1. In a textile machine, a spindle having. a rotated blade, a spool mounted on and rotated with said blade, a member which supports said spool on said blade, and means to change the axial position of said member relative to said blade by selective segmental adjustments of predetermined .amount.

2. In a textile machine, a spindle having a rotated blade, a spool mounted on androtated with said blade, a support for said spool on said blade, coacting segmental helical elements fixed relative to said support and blade and constituting axial adjusting means for said support, and locking means to positively retain an adjusted angular relation of said support tosaid blade. 1

3. In a textile machine, a spindle having a rotated blade, a spool mounted on and rotated with said blade, a driving whirl fixed to said spindle, and a spool-supporting cap rotatably mounted on said whirl, said cap and whirl having a plurality of coacting segmental helical surfaces together making up a circumference and each extending not over and which, when relatively adjusted angularly, change the axial relation of said cap and blade. I

4. In a textile machine, a spindle having rotated blade, a spool mounted on and rotated with said blade, a support for said spool on said blade, means to change the relative axial relation of said supportand blade by a change in the angular position of said support relative to said blade, and toothed means to positively lock said support to said blade in any selected one of a plurality of different angular positions relative thereto.

5. In a textile machine, a spindle having a rotated blade, a spool mounted on and rotated with said blade, a whirl to drive said blade, and a spool-supporting member mounted on said whirl, said whirl and member having coacting toothed helical portions constituting axial adjusting and locking means for said member on said whirl and blade.
