SUPPORT FOR SPINNING-SPINDLES.

SPECIFICATION forming part of Letters Patent No. 406,823, dated July 9, 1889. Application filed May 1'7, 1889. Serial 110.311,177. (No model.)

To all whom, it may concern:

Be it known that I, WILLIAM F. DEAPER, of I-Iopedale, county of Worcester, State of Massachusetts, have invented an Improve- 5 ment in Support-s for Spinning-Spindles, of

which the following description, in connection with the accompanying drawings, is a specification, like letters on the drawings representing like parts.

1o In the invention to be herein described the spindle has a loose lateral bearing near its jnnction'with the sleeve-whirl, and the step in which the foot of the spindle rests and turns is sustained by and free to rock or tip I5 upon a step-support located at or near the line of band-pull.

Figure l, in partial elevation and section, represents a spindle and bearing embodying my invention, and Figs. 2 and 3 modifications 2o to be described.

The supporting-ease or `holder A, seated upon the usual rail A and held in place by the nut A2, receiveswithin it the step-support a, concaved or recessed at its upper side.

2 5 The pintle of the spindle b, having a sleevewhirl b', is surrounded above the grooved part of the whirl by a lateral bearing (shown as a tube) c, loosely mounted in the supporting-case, and the foot or extremity of the 3o pintle rests in a step portion d, sustained by the step-support, so as to enable the step to rock, swivel, or tip at or nearly in the line of the usual band-pull.

In Fig. l the portion c of the bolster or lat- 3 5 eral bearing is in one integral piece with the step portion d, but in Fig. 3 the two portions are separated, and the bolster-bearing portion is rested loosely upon a shoulder 2.

In Figs. l and 3 the lower end of the step portion is made spherical, but in Fig. 2 the 4o lower end of the step portion is made conical, as at 4, to enter a conical seat in the stepsupport a.

I do not broadly claim a spindle-step having a partial spherical bottom; but prior to 45 my invention I am not aware that a bolster and step bearing has ever had its lower end seated to rock or tip on` a step-support; nor am I aware that a loose lateral bearing and step portion have ever been combined with a 5o supporting-case or holder and sleeve-whirl spindle in such manner as to enable the step portion to rock or tip in a line at or near the line of band-pull.

The bolster and 'step-bearing portions will 55 vcontain usual oil-holes.

I claiml. The combination, with a spindle, supr porting-case or holder, and step-support, of a bolster' and step bearing swiveled at its lower 6o end to rock or tip on the said step-support, substantially as described.

2. The combination, witha supporting-case or holder, a step-support, and a sleeve-whirl spindle, of a loose bolsterand a step portion, 65 the latter being free to rock or tip at or near the line of the band-pull, substantially as described.

In testimony whereof I have signed my name to this speciiication in the presence of 7o two subscribing witnesses.

INM. F. DRAPER.
