SFECFICATION forming part of Letters Patent No. 39l,4=62, dated October 23, 1888.

Application filed March S), 1888. Serial No. 266,730. (No model.)

To @,Z whom) it 71mg/ concern,.-

Be it known that l, WILLIAM F. DRAPER, of Hopedale, county of Vorcester, State of Massach usetis, have invented an Improvement in Supports for Spinning-Spindles,ofwhich the following description, in connection with the accompanying drawings,is a specification, like letters on the drawings representing like parts.

rIhis invention has for its object to improve the bearings of that class of spindle having a sleeve-whirl and wherein all the bearings are located below the junction of' the whirl and spindle.

In another application made by me, Serial No. 261,035, I have shown a bolster-case provided with a bolster having rollingsurfaces, and in an application, Serial No. 266,729, I have shown such a bolster mounted in a bl'l ster-tube loose in the bolster-case. Herein I have shown a bolster-case provided with one loose bearing and with one bearing having rolling-surfaces, both inclosed in a bolster case or support.

My invention consists, essentially, in a bolster case or holder and a sleeve-whirl spindle, combined with a divided or compound bolster, one part of which is mounted loosely in the bolster case or holder, while the other part contains a series of rollingsurfaces, such construction enabling the spindle to be supported in such manner as to vibrate below its connection with the whirl, to thus accommodate :for uneven loading and avoid jarring or chattering, the rollingsurfaces reducing the friction between the parts, thus enabling the spindle to attain high speed with the expenditure of but little power.

Figure l in vertical section shows a spindle embodying my invention, the spindle being in elevation with the whirl in section. Fig. 2 is a section below the line fr, Fig. 1. Fig. 3 is a section in the line y, Fig. l, looking down. Fig. 4 shows a modified form of my invention with the spindle broken ofi' above the whirl; Fig. 5, a section below the line m; and Fig. 6 shows the spider by itself.

The rail A, the bolster case or support B, the nut C, and the spindle D, having the sleevewhirl D', are and may be all as usual.

The bolster case or support receives within "it a divided or compound bolster composed of a tube-like portion, a, in which the spindle below the wheel has a running iit, and a portion, as b, having a series of rollingsurfaces, the said rolling-surfaces being herein shown as short cylinders held by a spider, as c, (shown separately in Fig. 6,) the said rolls and spider being common to my application, Serial No. 261,035.

In Fig. l, the slecvelike bolster portion has a collar or flange, a, at top to rest upon the bolster case or support near its upper end, the said portion being therein shown assurrounded by an elastic or yielding packing orjacket, d. The head or dange of the portion a hasa notch, (see Fig. 7,) which is entered by a lug or projection at the upper end of the bolster case or l support to thus prevent the rotation of the portion a. The outside of the spindle bears against the rolling-surfaces, and the latter fit the space between the spindle and the inner wall of the bolster case or support..

In Fig. 4, I have shown the portion of the bearing having rolling surfaces as located near the upper end of the bolster-case rather than near its lower end, as in Fig. 1, the bearing portion a, bored to receive and iit the spindle, being restrained from rotation by a pin or projection, c, the said portieri a in Fig. i being shown as bored for but part of its length, so as to form a step-bearing.

In this invention the rolls located between the spindle and the rigid case or support outside ofit, and also within the sleeve-whirl, and substantially in the line of the band-pull,lessen friction between the spindle and its surround` ing bearing, while the loose or yielding portion, as (i, moves to accommodate for the viw bration of the spindle under an unbalanced load.

Instead of the iibrous packing, cork or metallic springs, or any usual means for enabling the bearing to move against an elastic pressure, may be used without departing from my invention, and would be within the scope of the term elastic packing.77

I claiml. The bolster case or support and the sleevewhirl spindle, combined with a double or compound bearing, consisting of a sleevelike portion, c, fitting the spindle, and a portion, b, having rolling-surfaces, both the said IOO bearing portions being located Within the said bolster case or support, substantially as described.

2. The bolster case or support and the sleeve-Whirl spindle, combined with a double or compound bearing, consisting of a sleevelike portion, a, fitting the spindle and loose in the said case or support, means to prevent it from rotation with the spindle, and a portion, b, having rolling-surfaces, both the said bearing portions being located Within the said bolster ease or support, substantially as described.

3. The bolster case or support and the sleeve-Whirl spindle, combined with a double or compound bearing, consisting of a sleevet5 like portion, a, fitting the spindle and loose in the said ease or support, and the surrounding elastic or yielding packing, and a portion, b, having rolling-surfaces, both the said bearing portions being located Within the said bol- 2o ster case or support, substantially as described. In testimony whereof I have signed my name to this specification in the presence of two subseribing Witnesses.
