SUPPORT FOR SPINNING-SPINDLES.

SPECIFICATION forming part of Letters Patent No. 410,355, dated September 3, 1889,

Application filed June 15, 1889. Serial No. 314,485. (No model.)

side the whirl, and by it returned back into 1 the supporting-case.

In accordance with my invention,the lower end of the sleeve-whirl is of such diameter that the annulus or ring surrounding it may be lifted above the lower edge of the groove and up to the band in the band-groove, when it is desired to introduce the snout of an oilcan into the space within the curb of the supporting-case to oil the spindle and bearing. This annulus or ring is shown as without holes, so that it actuallye iudes the entrance of lint and dirt into the be ing, and oil is prevented from escaping to the outside of the supporting case or rail.

The drawing shows in partial elevation and section a spindle and bearings therefor, together with the annulus or ring, the latter being shown by dotted lines as elevated for oiling.

The rail A sustains a supporting-case B, which is held in place by a nut O, of usual construction.

The spindle D has an attached sleeve-whirl D, the lower end 2 of which below the bandgroove 3 is of substantially the diameter of the whirl at the point 4, designating the lower edge of the groove of the whirl which receives the band, the said lower end 2 of the said sleeve-whirl constituting by its external portion a guide for the annulus or ring a, so that the latter, were it not for the band in the band-groove, would cross the band-groove.

The annulus or ring awill preferably have a flange a to aid in lifting it when it is desired to enter the snout of an oil-can into the space below the lower end of the said sleeve whirl and between it and the curb 5 of the supporting-case, to enable the bearing to be oiled. The annulus or ringis preferably without any transverse oil-hole, and in practice it enters a groove cut in the curb 5, and has a loose fit about the sleeve-whirl,the space a between them being, however, suificient to permit of the proper movements of the spindle in centering itself.

The lower end of the sleeve-whirl is of such shape and length as to enable the annulus or ring to be lifted above the lower edge 4 of the band in the band-groove, which could not be done in an y spindle construction known to me.

The nearer the annulus or ring can be moved to the line of band-pull, (the center of the whirl, where it is of least diameter,) the shorter may be the sleeve-Whirl, and yet enable it to co-operate with the annulus or ring, while the latter bridges the space between thelower end of the whirl and the curb of the supportingcase.

Between the bolster b in the supportingcase and the spindle I have shown a series of inclined grooves 6, so made as to enable the oil to be lifted by the spindle in its rotation, the oil rising above the topof the bolster and bolster-case, and being discharged against the inner side of the whirl, down which it runs, itbeing discharged from the lower end of the sleeve-whirl at a point below the top of the annulus or ring a, the interior of the latter directing the oil into the interior of the curb, and preventing any oil from getting outside the said curb and on the rail. The oil entering thesupporting-case inside the curb 5 passes to the bolster through the oil-hole 8, and then through holes 10 to the spindle.

To insure the discharge of the oil from the bolster directly to the interior of the whirl 0 the upper end of the bolster will be extended above the supporting-case.

I do not desire to limit my invention to the particular means used to cause the upward circulation of oil in the bolster, as instead of the grooves I may use any other well-known and usual means-as, for instance, the taper of the spindle may be such as to cause the oil to rise between it and the bolster.

By the construction herein described the oil I00 is kept in constant circulation so long as the spindle runs.

It is obvious that the operation of the annulus a would be the same with relation to the sleeve-whirl whether the bolster-bearing in the supportingcase is separate therefrom or integral therewith.

The bolster-bearing, if separate from the supporting case, will preferably be loose therein.

I am aware that thelower end of the sleeve- Whirl has been surrounded by an annulus having a slight vertical movement when oiling; but prior to my invention I amnot aware that the said guide has been large enough to permit the ring to rise up to and partially across the ba11rl-groove,if desired.

I claim- The combination, with a supporting-case having a curb, a bolster-bearing, and anoilhole, and a SlBQVG-Wlllll spindle having an extension 2 below the band-groove, the diameter of the said extension being as great as that of the sleeve-whirl at the lower end of the band-groove, of an annulus or ring a, adapted to be lifted vertically outside the said extension up to and across the band-groove, thereby uncovering the space between the lower end of the whirl and the cover of the supporting-case, the lower end of the said annulus or ring entering the said curb, to operate substantially as described.

In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.

GEORGE O DRAPER.
