SPINDLE AND BEARING THEREFOR.

SPECIFICATION forming part of Letters Patent No. 261,275, dated July 18, 1882.

Application filed April 20, 1882. (No model.)

` To all whom it may concern:

Be it known that I, GUsTAVUs E. TAFT, a citizen of the United States, residing at Whitinsville, in the county ot' Worcester and State of Massachusetts, have invented certain new and useful Improvements in Spindles and Bearings therefor, of which the following is a speciiication.

My invention relates to spindles and bearings therefor used in spinning ne yarns; and the objects of my improvements are, iirst, to provide the spindle with a combined bolster and lstep having a springy stem with which no packing will be required for said spindle to run true and uniformly; second, to alibrd facilities for the proper adjustment of the combined bolster and step in relation to the bolster-case.

I attain these objects by the constructionillustrated in the accompanying drawings, in which- Y Figure 1 is a vertical section, showing a spindle, its bolster, step, and bolster -case constructed according to my invention. Fig. 2 is a vertical section through the bolster, the step, and its springy stem. Fig. 3 is a vertical section through the case or holder constructed to receive the bolster-step and springy stem.

Heretofore many attempts have been made to prevent the jarring, wabbling, or uneasy motion of running spindles caused by any inequality of bobbin or yarn load on the spindle, and thus reduce the wear of the bearings, the most common method being by means of elastic packing or springs placed around the bolster; but their properties seldom'last for any length of time. By my construction no packing is required, and the means used to give `elasticity and freedom of adjustment to the is transmitted to the spindle. Y This spindle is Vsupported sidewise by the bolster B and end- These parts B B areA Wise by the step B. formed in one piece, and are provided with a springy stem, B2, secured to the lower end of the step or formed integral therewith. These parts B B B2 above mentioned are inclosed in a deep bolster-case, C, having a series-of chamv ameter ofsuch size as to fit the outside of the bolster at its largest part b. The part bis a narrow belt of bearing-surface approximately opposite the position occupied by the Whirl a' when the spindle is secured upon its step. Above and under this part b the surface of the bolster tapers sufliciently to allow the spindle and` bolster t0 adjust themselves to the axial center of the load on the spindle, and at the lower end ofthe part b, where it joins the bolster-tube b', there is produced a shoulder, bit, to Vsupport the bolster. At the lower end of the chamber c there is formed in the bolstercase a shoulder-seat, c', to support the bolster at that point. The chamber c2, formed in the bolster-case under the internal collar or shoulder seat, c', is of larger diameter than any of the other chambers formed therein, and can contain a two or three months7 supply of oil. Under the chamber or oil-reservoir c2 the internal bore, c3, of the bolster-case is of suitable size to limit the motion of the lower end of the bolster-tube b or the step B', and the size of thisybore governs it, so there will not be motion enough to havethe springy stem injured by any jerk or allow it to yield more than is desirable.

Bronze being regarded as the best metal for bearings, I generally construct the combined bolster and step of that metal and the springstem B2 of steel, and unite the parts by means of a line screw-thread cut upon the upper end of said stem. The lower end, b2, of the stern B2 is of such a diameter as to make a close sliding t in the bottom of the bolster-case, and it is forked -or slotted to straddle a pin, c, secured in the interior of said bolster-case, to keep the bolster from rotating under the impulse of the Ispindle. The pendent springy stem B2 is of suitable size and elasticity to bend under a side pressure applied to the spindle, so that the bolster and step connected with the springy stem may adjust themselves to any deflection of spindle from its normal alignment, thus preventing wabbling or vibrating motion ot' the spindle. The bolster, its step, and the stem B2 may be made in one piece, of steel or other suitable metal.

The bolster-caseC is secured to the spinningframe rail D by a nut, E, put on the threaded part thereof. It is east in one piece, so that no oil canleak out at the bottom, and when covered bythe whirl no dust can get in at the top. To supply the spindle-bearings with oil, the hooked wire c is turned from over the whirl, the spindle with its whirl is removed7 and oil is poured in at tbetop of the bolster and finds its Way through the openings fin the bolster to the upper beariugofthe spindle, and through the openings g in the bolster-tube b to the step of the spindle.

Having now fullydescribed my invention, I claiml. The combination of a bolstercase having a closed bottom with a combined bolster and step provided with a light springy stem secured to or bearing against the bottom of the said case, substantially as and for the purpose described.

2. The combination ot' a bolster-case,pr0 vided with superposed chambers of different diameters, with a combined bolster and step having only a narrow belt fitting in the upper chamber ot thc case, and provided witha. light springy stem secured at its lower end to the sides of the lower chamber of the said case, substantially as and for the purpose described.

3. The combination ot' a bolster-case bored centrullyto produce communicating chambers of different diameters, an internal shoulderseat, c', and a closed bottom, with a combined bolster and step provided with it bearing, b, having a double conical periphery above and under said bearing, and shouldered to rest upon the shoulder-seat c', and :t pendent springy stem having its lower end secured to the said case, substantially as and for the purpose set forth.

4. The combination of a livespindle, provided with a sleeve and whirl, with a bolstercase haring a chamber, c3, of such diameter as wil. limit the motion ofthe step, as described, au internal oil-chamber, c2, and a combined bolster and step provided with side perforatious and a pendent spriugy stem, substantiall'v as and for the purpose set forth.
