Description

July 15, 19414A F. E. KELLEY SPINDLE Filed sept. 19, 195s Patented July 15, 1941 UNITED` STATES PATENT OFFICE y SPINDLE Francis E. Kelley, Providence, R. I. v Application September 19, 1938, Serial No. 230,597
(Cl. sos-149) 2 Claims.
This invention relates to spindles used in spinning and twisting operations.
It is the general object of my invention to provide a spindle so constructed that larger and heavier bobbins or spools may be run at higher speeds and with reduced vibration.
A further object is to provide a spindle in which the vibration due to an unbalanced load will be substantially decreased.
My invention further relates to arrangements and combinations of parts which will be hereinafter described and more particularly pointed out in the appended claims.
A preferred form of the invention is shown in the drawing, i-n which Fig. 1 is a `sectional side elevation of my improved spindle;
Fig. 2 is a partial elevation, looking in the direction of the arrow 2 in Fig. 1; and
Fig. 3 is a sectional plan view, taken along the line 3-3 in Fig. 2.
Referring to the drawing, I have shown a twister spindle comprising a base I adapted to be clamped to a rail Il by a nut l2, and a bearing bolster I5 supported therein and held from rotation by a key l5. A spindle blade 20 is provided with an upper ball bearing 2| mounted in the holster l5 and also with a lower bearing 22 similarly mounted.
The usual whirl 24 is mounted on the blade 20 and is recessed to extend down over the upper end of the base l0 and bolster I5. The whirl 2d is thus adapted tc be engaged by a driving belt in substantial alignment with the ball bearing 2|.
The parts thus far described are of the usual construction and in themselves form no part of my present invention, which relates particularly to the manner of supporting a spool S' on the blade 20,
For this purpose, l provide a sleeve 30 having a supporting member 3| fixed in its upper end and rmly secured on the reduced upper end 32 of the spindle blade 20. At its lower end, the sleeve 30 is provided with a iiange or disc 35 having driving lugs 36. A metal cap 40 secured to the bottom of the spool S rests on the ange 35 and is slotted to receive the driving lugs 36.
It will be noted that the under side of the flange 35 is spaced from the top surface of the whirl 24, and also that the interior surface of the sleeve 30 is substantially spaced transversely from the blade 20, to which blade it is attached at its upper end only by the supporting member 3l.
The weight of the spool and its load is thus supported entirely from the reduced upper end portion 32 of the blade 20.. The upper portion of the blade 20 also has suilicient resilience topermit the lower portion of the sleeve and spool to be yieldingly displaced transversely relative to th-e blade 20 and to its bearings.
The advantage of this construction lies in the fact that an unbalanced spool or a spool with an unbalanced load may self-adjust itself transversely relative to the spindle blade, thus centralizing the load on the spindle and preventing the excessive wear and pounding of the bearings which is commonly caused by rotation ci unbalanced loads at the high speeds now prevalent.
While I have shown my invention embodied in a certain form of twister spindle, it will be evident that the invention may be similarly applied to other forms of spinning and twisting spindles, as it is not dependent upon the detailed structure of the spindle but resides primarily in the provision of a load-supporting sleeve which is connected to the spindle blade at its Auper end only and which is otherwise spaced from the blade and clear of the driving Whirl.
Having thus described my invention andthe advantages thereof, I do not wish to be limited to the details herein disclosed, otherwise than asset forth in the claims, but what I claim is:
1. Ina yarn producing machine, a spindle having a blade which is'slightly resilient in its upper portion, a driving whirl xed to said blade, bearings for said blade positioned entirely below the point of attachment of said whirl to said blade, a load-carrying sleeve permanently iixed to the extreme upper end portion only of said blade and elsewhere free 'and substantially spaced from said blade and said whirl, a spool-supporting flangeA xed to the lower end of said sleeve but. free from said blade and whirl, and means on said flange to coact with and positively rotate a spool supported on said ange.
2. In a spindle assembly, a. made with a driving whirl iixed thereto, bearings for said blade positioned entirely below the point of attachment of said whirl to said blade, a load-carrying sleeve fixed to the upper end portion only of said Y
