To all whom may' concern.'

Be it known that I, OSCAR C; SIDILAU, of

Shirley, in the county of Middlesex and.y

State of Massachusetts, a citizen of the United States, have invented a new and useful Improvement in Spindle-Bases, of which the following is a specification.

My invention relates especially to spin-v` dles to be used in coarse spinning where there is considerable lint and fly which gathers about the spindle and forms an increasing drag upon it` so that considerable increased friction results, and frequent cleaning becomes necessary.

It consists in an improvement in the spindle base by which not only is the gathering of lint prevented but also the scattering of the oil which sometimes overflows the top of the base' and when it reaches the bottom of the sleeve which carries the whirl is thrown off by the rapidly rotating spindle and discolors the yarn upon the neighboring spindles, and spatters the frame.

My invention will be understood by reference to the drawings, in which- Figure l is a plan of a spindle embodying my invention, the top of the blade of said spindle being shown in section; Fig. 2 being a section on line 2 2 of Fig. 1.

A is the base in which is the bolster B which is suitably packed as at o.

C is the blade having the cap c and the whirl 01 hanging from the sleeve c2.

With the exception of the base A and its arrangement with the blade the parts as shown all represent a well known t-ype of spindle and need no further description as to detail. f

rl`he base A has the usual oil tube a which is connected by the passa-ge al with the packing I) about the bolster B. The upper surface of that portion of the base through which the oil is fed instead of being flat as is usual is flanged upwardly to forni a cup, the flange a2 of which is sufficiently high to form a guard to the lower edge of the sleeve c2 which in spindle shownis formed by the whirl c1 while the bottom of the cup a3 serves to catch any oil which may flow down around t-he tubular portion A1 of the base which steadies the upper part of the bolster and the blade. The interior diameter of the portion a2 of t-he base should be substantially the same as the exterior diameter of the whirl or other part which is to act as a guard inc orderk that there may be no opening or chance forflintto ybe caught and workits wayinto the oil cupw'ithin theflange or to collect soas to form afbearing constantly increasing in size which will add additional and undesirablefriction to the rotating blade. The tworparts,'however, should of course be sufficientlyloose with relation to eachother to allow perfectly free rotation onlthe part of the spindle.

It is well known that when the spindlev vibrates in thebolster, it frequently causes f the oil to be pumped up around the bolster and over the top of the tubular portion of the base and down the interior of the sleeve carrying the whirl and isA thrown out laterally by centrifugal force. The improvement above described prevents this as the flange of thebase catches the oil and leads it to the bottom of the cup, but what is of equalimportance is the fact that it protects the blade from collecting lint and fly which renders my construction a great improvement over any construction now known to me. It is evident that this construction may be utilized upon otherv formsof spindle than that shown, its novelty lying in the making of what may be `termed a flush jointbetween the upper end of the flange and the Sleeve whereby the two parts shall be as 'nearly in contact with each other asis practicable kwith a View to free rotation of the spindle and shall offer no edges for theycollection of lint or fly. Thus the operation of the sleeve which lies within themouth of the flange forms a. close cover for'the oil chamberand at the same time serves to prevent this lint collection. f

It will be noted that the oil tube a and passage a1 are not connected with the cup formed by the flange a2 and this is of advantage because it enables the tube to be made sufliciently long to contain a fairly large supply of oil. If this tube were connected with the cup there would of course be an. overflow until the supply in the tube reached a level rather than the top of the cup. If the construction of the spindle is such that oil cannot be thrown by the blade the cup form of the device may be changed, the cavity a3 being unnecessary, the flange a2 being useful in this case to prevent the indraft of lint.

As shown the whirl forms the lowerfedoe of the sleeve but where the sleeve extends below the whirl the flange may slightly overlap it or the whirl, as seems best, the purpose of my invention being to prevent the spattering Vof the oil and the indraft of lint, in other words, to serve as a guard to the lower portion of the sleeve.

What I claim as my invention is In a spindle, a blade having a downwardly projecting sleeve, a base having an upwardly projecting flange surrounding and overlapping the lower edge of said sleeve and forming a cup, said sleeve forming a sliding fit with. the interior edge of said cup, terminating just within said cup, and serving as a closure therefor, a bolsterto receive said blade, said sleeve surrounding said bolster and receiving in its interior oil pumped up thereby and delivering it from the lower edge thereof to said flange, said base having Y an oil passage communicating with said bol- JOHN E.
