SPINNING-FRAME SPINDLE AND ITSBOLSTER.

SPECIFICATION forming part of Letters Patent No. 295,899, dated April 1, 1884-.

Application filed May 15, use. (No model.)

To all whom it. concernr C Be it known that 1, JOHN BIRKENHEAD, of Mansfield,in the county of Bristol, of the Commonwealth of Massachusetts, have invented a new and .useful" Improvement in Spinning Frame Spindles. and their. Bolsters; and I do hereby declare the same to be described in the. following specification and represented in the accompanying drawings, of which- Figure 1 is a front elevation, and Fig. 2 a vertical and transversesection, of a spindle, a bolster-rail, and bolster provided with myinvention,the nature of which is duly set forth in the claims hereinafter presented; also, a bobbin as applied to the spindle. Fig.13 is a vertical section of a bolster provided with sta tionary instead of removable bearings. Such figure shows the spiral groove in the bore of such bolster. The groove is also represented inQFig. 2, wherein it appears as in the bore of the bolster and in that of the removable bearings thereof. Fig. 4 is a horizontal section of thebolster and its upper removable bearing sleeve on the line as m, Fig. 2. p

The bolster for the spindle extends up through and both above and below its sustaining-rail, and projectswithin an oil cup or reservoir fixed to the spindle at its foot, and combined or being in one piece with. the whirl. In the whirlj is a mouth'or passage leading from the top of the said whirl into the oil cup or reservoir below the whirl. The whirl and oil-cup are concentric with the spindle and the part of the bolster extending down within them. The boreof the bolster and the spindle-bearings within said bolsters are grooved spirally from the foot to the top of the bolster in such manner that while the spindle may be in revolution for spinning the yarn oil shall be caused to flow. from the oil-cup upward through the bolster andthe spindle-bearings to the top of the bolster. The spindle at its foot does not rest and turn in any step, but at the top of the bolster such spindle is provided with a collar flange or hearing to rest directly on the said top, or uponthat'of a removable metallic sleeve or upper spindlebearing inserted in the bolster. Furthermore, the said spindle collar flange or hearing, by which the spindle is kept from dropping downward in the bolster, is formed with'an annular lip to extend from it into an annular groove 'or chamber made inthe bolster at its top. This annular groove is to intercept any oil that may escape between the top of the bolster and the spindle collar or flange resting thereon. The annular lip serves to deflect such oil into the said groove or chamber, and to keep it from being discharged over the chamber and bolster by centrifugal force while the spindle may be in revolution. At the upper part of the oilcup, and within the whirl, there is an enlargement or an annular groove or chamber provided at top with an annular lip or flange, which extends down within such enlargement or groove, and with it serves to prevent oil, while the spindle and cup and whirl may be in rapid revolution, from beingthrown out of the cup.

In the drawings, A denotes the spindle; B, thebolster, and O the bolster-supporting rail, the bolster being held in the rail by a set-screw or other proper means. D is the oil cup or reservoir, and E the whirl. F is the spindlesustaining flange collar,or uppermost bearing,

it resting on the top of the bolster or that of a brass bearing-sleeve, G, surrounding the spindle andarranged within the bolst'er concentrically. Another such sleeve is shown at H as inserted in the bolster at its lower part. Each sleeve may be encompassed with yielding packing or cloth sleeve I. The bolster, however, can be constructed without the re movable sleeves G and H, but with stationary spindle-bearings, as represented at G and H in Fig. 3.

The enlargement or annular chamber in th whirl and ,oil-cup is shown in Fig. 2 at a, the mouth or passage at a, and its annular lip or flange at b. The spiral groove in the bolster and the spindle-bearings of its bore is represented at 0. Instead of forming such groove in the bolster and its spindlebearing, it may be made in and around the spindle itself; but it is better to have it in the bolster and the said bearings.

Theannular chamber in the top of the bolster is shown at d, the lip projecting down into it from the flange collar, or uppermost bear ing, F, being represented at 6.

Oil for supplying the cup at the foot of the spindle is to be poured into the mouth formed in the whirl.

When the spindle may be in rapid revolution by a,band applied to its whirl, the oil will be forced or drawn from the oil-cup upward through the bolster to the bearing-flange of the spindle, and will lubricate the bearingsurfaces of the spindle and bolster.

I claim- 1. The bolster having the spindle collar flange or bearing and the surrounding oil-intercepting chamber in its upper part, as set forth, in combination with the, spindle extended down through the bolster, and provided not only with the flange orcollar to rest on and encompass the aforesaid bearing, but with a combined whirl and oil-cup adapted to the said spindle at its lower part, having a mouth or passage opening into the said cup, and arranged with the bolster, as represented, the bore of the bolster having a spiral groove, as and for the purpose explained.

2. The bolster provided with the separate bearing-sleeves arranged in items represented,

in combination with the spindle extending through and above such sleeves, and having not only the flange or collar to rest and revolve on the top of the upper of such sleeves,

but the combined whirl amd oil-cup adapted the said bearing-sleeves, and having not only the flange or collar to rest and revolve on the top of the upper of such bearing-sleeves, but the combined whirl and oil-cup adapted to it the said spindle, and arranged with the bolster, all being substantially as represented, J OHN BIRKENHEAD.
