SPINDLE Fil'ed Sept. 26, 1928 A m ww M W W mO MJ BX w 2 Patented Apr. 28, 1931 UNITED STATES CHUSETTS I PATENT oFF cr.
BERTRAM R. swEE'r, or WHITINSVILLE, MAssAofiUsE'rTs, As'sIGNoR T wrrrrriv IVlTA- h CHINE WORKS, or WHITINSVILLE, MASSACHUSETTS, A ooRroRATIon o 'MAssA- SPINDLE Application filed September 26, 1928. Serial No. 308,400. g
This invention relates to spindles used in spinning or twisting yarn and relates more particularly to the heavy type of spindle commonly used in twisting operations. Such spindles are required to carry relatively heavy spools or bobbins and all parts of the spindle must be of correspondingly heavy construction, with extended bearing surfaces.
It is the common practice in spindle construction to mount the blade or shaftof a spinning or twisting spindle in a long sleeve, commonly termed a bolster, which fits more or less snugly in a cast iron spindle base or bolster casing which is secured to the spindle rail.
It is one object of my invention to improve the bearings of a spinning or twisting spindle by providing a two-piece bolster, the upper portion preferably having a straight bearing for the cylindrical middle portion of the spindle blade and the lower portion preferably providing a tapered step bearing for the lower end of the spindle blade.
I also provide increased oil storage in a spinning or twisting spindle and make more eflective provision for the circulation of oil therethrough.
An important feature of the invention also relates to the provision of an improved step or thrust bearing for the lower end of the spindle.
My invention further relates to arrangements and combinations of parts which will be hereinafter described and more particularly pointed out in the appended claim.
A preferred form of the invention is shown in the drawings in which 7 Fig. 1 is a vertical sectional view of my improved spindle;
ster member;
Fig. 3 is a front elevation of the lower bolster member; V
Fig. 4c is a sectional plan view, taken along the line 1-4: in Fig. 1; and
Fig. 5 is a side elevation of the spindle step.
Referring to the drawings, I have shown parts of a spindle comprising a blade 10 having a driving whirl 11 secured thereon. The
The base 15 is provided with .a vertical opening 17 to receive the bolster members 12 and 13,and. aslot or guideway 18 is formed in the upper part of the opening 17 to receive keys 19 and 20, inserted in the bolsterv members'12 and 13. 1
The upper bolster member 12 is provided with a flange 12'' adapted to be seated 'on' an inclined'surfac'e 21 'of the. base 15 and by which the member 12 is vertically'positioned. The lower bolster member 13 engages a central projection 22in the bottom of the opening 17 and is thereby vertically. positioned. An oilpassage 25 connects at its lower end with the opening'17 in the spindle base and is closed at its'uppm end by a cap26, which also acts as a doifer guard and is provided witha projecting portion'27 on the whirlll; I z r The blade 10 is provided with a cylindrical bearingportion 10 intermediate its length; and with a teiperedlower end portion 10". The lower end of the spindle blade prefer-v ably. terminates in a flattened conical portion 30, engaging a hardened step 31 mounted in the lower end of the bolster member 13 and preferably flattened at its upper end as indicated in Fig. 5.
The lower bolster'member 13 is provided with a tapered bearing portion 32 engaging the lower end portion 10 of-the spindle blade overlying the flange 10*. It Will be noted that the bolster members 12 and 13 are spaced substantially apart vertically, providing an oil storage space 36 between said members, with which space the oil passage 25 directly communicates.
The bolster member 12 is provided with one or more vertically extending grooves 40 (Fig. 2) and the lower-bolster member 13 is provided with one or more similar grooves ll in its upper portion, said grooves 40 and 41 also facilitating the circulation of oil through the spindle-bearing; V
Having described the details of construe tion of my improved spindle, the advantages thereof will be readily understood. The two piece construction may be manufactured much more accurately than the one-piece bolsterwitlr its very long bored hole which was foundtobe extremely diffieult to produce with a, straight axis.
, Furthermore, the separation of'the upper and; lower bolster members greatly improves the: oil, circulation through the spindle, and the provision of the hardened steel step 31 in a spindle of this type greatly reduces the wear at, the lower end of the spindle. It is foundthat spindles manufactured as hereindescribed run very accurately and maintain their accuracy of operation for a long period oi time. c
Having thus. described: my invention and the, advantages thereof, I do not wish to be limited to. the detailsherein disclosed, otherwise than as set. forthin the claim, but what I claim is-;
In. a. spindle. construction, a spindle base having avertically extending openingtherein aspi ndleblade, a two-piece bolster providing upper and lower bearings for said blade,,the lower'bolster member havinga tapere'd' bearing for the lower end portion ofthe' spindle blade, and a hardened step mounted insaid: lower bolster member and formingan end thrust bearing for said spindle blade. In testimony whereof I have hereunto affixed my signature. 1 7 I o BERTRAM R. SWEETL
