Be `it `known that lI, Fin-ib NORTH, -a States, residing at Winchester, in the county yof Middlesex `and State of Massachusetts, 4,have `i'nver'ited Enew yin 'Spinning- Spi'ndles, of which the followi'ng is a "specititration. A n

with a bolster mounted adjacent its upper extremity upon the pase by means adapted to operate 'as a ",fulerum` a spiral centering spring which `e1'r`ib`race`s` vthe "tip of the holster .lower extremity and opposes and limits` lotl eral movement 'fot the bolster, 'a grease cup communicating with lthe interior of the bolster, and a self .adjustinghelcal spring which bears upon the spindle blade step 'and maintains a-con'stant and uniform pressure upon both `upper and/,lowermb'earing balls and normally retains the `ball bearingllements inther proper 'relatomr A `lfurther contribution to the feature of darabilit'y re- Sides in the elimination from in'ydevice` of the fine threaded 'stem and, adjusting p'liigin the holster, as Well as allother threaded ports, and the extremely delicate bolster spring formerly employed;

Aextremity with the cone 12 supported within the holster i u'poirthe halls 6 'which are contained in the ball race? in the step 8. The Step 8 is 'slidable within thexbolster and is provided with 'a downwardly extending Stern 9 Ythe 'lofiver end of which .isreceived within the central aperture 10 in the guide 11 `'fitted within the lower endof the bolster.

The spring 13 further acts as a cushion to absorb shock and 'protect the lowerball bearing'as when an operator holding' the blade strikes the 'Spindlelbase ak sharp blow. jThe guide 11 isalso provided with a downwardly extendinglr stein y15 ywhich forms the tip' of the holster and which is embraced in Contact by the top convolution" of the conical spiral springr 16 and'protrudes through the central aperture (17 in the cap 18 which frictionally engages the outer KAwall of the .spindle base andsupports'thespring 16, the bottom convolution-of which is in Contact throughout the ,greater-portion of its length with the base wallA and thus vheld firn'llyy inposition.

The diameter of the aperture 1'? in theeap 18 is .substantially greater than that of the stem 15' and thus cooperates with the space between thebolster Wall and hase Wall to permit of lateral movement of the bolster in all directions. That portion of the aperl ture l() in the guide. 'll which lies within the stein 15 is interiorly screw threaded tu engage the screw means of which grease istforced up through the well 21 in the step St-o the interior of the bolster to liibrieate the ball bearings upon which the. blade 5 is rotated.

The upper bearing in which the blade 5 rotates consists ojt the cone 23 pressed on the. blade. the balls Z-l. and raceway :'22 in ball. cup The form oi ball race and cone which I employ is an important. ieature of my inif'ention. In general practice the diving pulleys on a spinning frame are mounted on a horizontal shaft. and rotaie. in a vertical plane, wherais the spindle. whirl rotates in'a horizontal plane. producing a quarter turn in the driving band whichexerts an upward or downward pnli on the blade, depending on the direction of move-A nient of the band. Preferably lor the. purpose of offsetting the. 'toreo of gravit)vv a quart...` turn which will impart an upward pull is adopted. Owing to theI fact tha-t the weight of the blade and other moving parts which it carries is substantially otl'set b v the upward pull of the. driving band and the only vertical stress on the bearings is that which results from the pressure of the.l

self adjusting spring.` appro.\imately five pounds. while the lateral pull ot the; driving band ranges up to eight pounds. the greater stress upon the bearing isobviously in a horizontal plane, and the resultant-,ot the two unequal toiics.ve1tical and horizontal., acting upon the bearing atan angle of fitr degrees is noty l degrees, but approximately Qt) degrees to the. horizontal. B v shaping the curve of the .race and cone so that ball diai'neters intersecting the central points ot' Contact between the race and ball and cone and ball shall with a horizontal plane. inv

sultant line kot force adapted to enable. the

bearing most vetlicientlv to perform the re-- quired lworh at the points otseverest applica'tion. Vihc degree of the. proper-angle depends upon the variance between the hori zontal and vertical' stress: the .more thc iormer exceeds the latter. the less the angle. lor practical purposes however the 2t) degree angle. will prove. highly .ellicicnt under Conditionsiisuallv prevailing. and a bearing constructed as hereinbcforc described may.

be coiiiineiiciallv operated with a. minimum of friction. Owing to the i'act that the pull ot the driving band is applied to the. blade above the upper bearing. alever Vfulcruined` on thatbearing is est ablishcd. and as the disytance from the upper iiiearing to the point is less tliaintliatv vrfrom the upper bea-ring to the lower. the horriontal stress on thelower hearing is less of applicationuoi liower threaded plug 20, by'

Fourteen balls are placed in the upper cup and the blade inserted vis then placed over the cup 25 and the whole placed in an arbor press with a lar e part of the press coming down and gripping the large end of bolster forcing it into thedie .which forms the end over the cup. The bolster and blade are then removed from the j press and reversed. Five balls are placed in l "the race 7 in the step 8 and the latter assembled with spring 13 and guide 11 and inserted in the lower endof bolster which is then placed in a spinning machine for spinning-the bolster into a. V-shaped recess inthe guide. The whirl and whirl base are then forced -on to the upper end of blade in an arbor press. The assembly is completed by inserting the bolster in the support 2 in the base with the stem 15 of the guide 11 engaging the spring 16 which has already been inserted as above described.

What I claim and desire to secure by Letters Patent isz' 1. In a spinning spindle, a base and a bolster mounted thereon by means adapted to prevent longitudinal movement of the bolster relative to the base, combined with a blade step vertically movable withinl the bolster and yieldingly supported therein.

2. In a spinningispindle, the combination of abase, a bolster supporte-'d at a point adjacent its upper extremity/1 by the base and adapted to move laterally in all directions upon said point as ffl" fulcrum, a spring mounted on the basemlapted to act upon the lower extremity of the bolster' and oppose lateral movement of the bolster with relation to the base, a step vertically movab-le within said bolster, a spindle blade mounted in bearings on said step, and a spring` adapted to bear upwardly on said step.

3. In a spinning spindle, the combination of a base, a bolster supported at a point adjacent its upper extremity b'y the base and adapted to move laterally in'all directions upon said point as a fulcrum, a spring mounted on the base adapted to act upon the lower extremity'ot' vthe bolster and oppose lateral movement of the bolster with -relation to therbase, a step provided with a vertical aperture within said bolster, a plug adapted to force grease through said aperture to the linterior of the bolster, and a spindle blade mounted in bearings on said step.
