Original No. 205,718, dated July 9, 18m Release No. $374, dated November 23, 1850. Application for reissue filed To all whom it may concern:

Be it known that 1, Joan Brsusnunno, of Mansfield, of the county of Bristol, of the State of Massachusetts, have invented a new and useful Improvement in Spindle-Bearings for Spinning-lllachines; and 1 do hereby declare the same to be described in the following specification and represented in the accompanying drawings, of which Figure 1 is a. side elevation, and Fig. 2 it vertical section, of a live-spindle and its adjuncts embracing my invention, a bobbin be ing also exhibited as applied to the spindle. Fig. 3 is a. top view of the oil trough or receiver. Fig. 4 is a. side view oi" the live-spindle and the combined cap and whirl and stud,

to be hereinafter explained. Fig. 5 is a side view, and Fig. 6 a vertical section, of the combined step and elastic holster. Fig. 7 1s a horizontal section taken through the spindle. bolster, and guard, to he hereinafter described.

In myimproved spinning mechanism the spindle A extends up through and is fixed to a tapering or conical cap, B, to which the whirl O is applied, or makes part of it, as shown, the cap being extended helow such whirl, as shown at a, and such extension being furnished with a short stud, b, to project from it externally. The said extension is to enter the mouth of the oil receiver or trough D, whose top is crowned or flanged inwardgas shown at c, and provided with a notch, cl, for the stud b to pass through. This stud, while the spindle is in place and revolving, projects underneath .the flange a, and with it serves to keep the spindle from rising in its bolster and step. This bolster (shown. at E) is a tube projecting up from the step F, and is slotted, scored, or grooved helically above the step, as shown at e e, in order to render the bolster elastic laterally. The spindle has its upper hearing within the upper part of the bolster, as shown at f, while its foot rests on the step, which is secured firmly in the tones g of the oil-receiver.

ster, is the tubular guard or standard G, there 5 trough into the step.

The helical slits or grooves of the bolster,

hesides answering to render it elastic, serve to cause the oil, during revolution of the spindie, to pass up into the spindle-bearing of the holster.

llhe cap B, by surrounding the spindle, holster, end guard, serves not only to intercept any oil that may be thrown otf laterally by the spindle, but to convey such oil back into the oilreceiver.

itlias been found in practice that with a rigid holster the spindle does not operate so well, and is more liable towear the bearing of the holster than is the case with a bolster that is elastic or can spring laterally a little. (Jousequently l have so constructed the bolster, which, nsnshewn, is directly fixed to or combined with the step. Thus the step and holster-hearing have what may be termed an elastic connection, to operate as described, the rigid guard surrounding this connection answering, to limit the lateral movement of the holster while the spindle may be revolving; or any force may be applied to the spindie to cause it to hend the holster laterally,

claim as of my invention is as follows:

i.-l he combined step and elastic bolster, substantially as and for use as described.

2. The combination oi the oil-reservoir with the connected step and the elastic bolster, essentially as specified.
