AURIN \VOOD, OF WORCESTER, ASSIGNOR TO THE SAIVYER SPINDLE COM PANY, OF BOSTON, MASSACHUSETTS.

SPECIFICATION forming part of Letters Patent N0. 383,091, dated May 15, 1888.

(Xoznodold To aZZ whom it may concern.-

Be it known that I, AURIN \VOOD, of -Worcester, county of Worcester, and State of Massachusetts, have invented an Improvement in Supports for SpinningSpindles, of which the following description, in connection with the accompanying drawings, is a specification, like letters on the drawings representing like parts.

This invention has for its object the production of an improved spindle-support capable of yielding to a limited extent to the requirements of the foot of the spindle as the latter gyrates or shakes when unequally loaded and rotated rapidly, the employment of elastic packing being dispensed with.

Myinvention is shown as embodied in that class of spindle-supports wherein a bolster made as a stiff tube is extended up into the sleeve-whirl and constitutes the only lateral bearing for the spring.

In accordance with my invention a stiff tube interposed directly between the pintle of the spindle and the sleeve-whirl and constituting a yielding bolster has attached to or forming part of it a spring-arm constituting a foot, the said plate being secured to a base, which may either be a block resting upon the bolster-rail or the bolsterrail itself, the arm permitting the bolster to yield or move to counteract injurious jar or vibration of the spindle.

Figure 1 in elevation shows a sleeve'whirl spindle supported in accordance with my invention, the spindle and the screw being in elevation, all the other parts being in section; Fig. 2, a top view of 1 with the spindle omitted, the cover-plate shown in Fig. 1 being also omitted; and Fig. 3 illnstratesa modified form of my invention.

The spindle a, its attached sleeve-whirl a, and the bolster-rail b are all of usual constrnction.

In Fig. 1 the rail Z) receives the shank c of a base, 0, which thus rests upon the rail at its upper side, the base being held in position by means of a nut, 0*. The yielding bolster to receive the pintle of the spindle constitutes the only lateral support therefor, it being interposed directly between the pintle and the sleeve-whirl, and not being connected to a rigid supporting-tube to thus take up room in the sleevewhirl, and is composed of a solid substantially rigid sleeve, (1, in which the pintle has a running fit, the said sleeve having at or near its lower end a connected spring-arm, e,

base or support for the bolster, the base 0' (shown in Fig. 1) being omitted from Fig. 3. In Fig. 3 the spring-arm e, shaped as shown in Fig. 2, is placed against the under side of the rail, which constitutes the base to which the arm is attached.

The bolster in Fig. 3 is shown as extended up through the usual hole in the rail, and the screw f enters the lower side of the rail.

In practice I prefer to employ the base 0, (shown in Fig. 1,) for the reason that such a base may be made to constitute an oil-well, and when the said base 0 is employed I shall provide a cover, as 0 to prevent dust, 850., from entering the well.

I do not desire to limit my invention to the exact shape of the spring-arm e, as its shape may be variously modified without departing from my invention. The shape shown for the arm in Figs. 1 and 2 is a desirable one, because of compactness, the arm being quite long, as will readily be seen by inspection of Fig. 2, wherein 2 and 3 represent open spaces. The yielding bolster extended upward into the sleevewhirl is the only tubular device or standard which enters the whirl, and hence the whirl may be made much smaller in diameter than were the bolster secured to and made an integral part of a rigid supportingtube extended into the whirl as far as the bolster extends into thewhirl, which has been done. I am also aware that a bolster-tube has been provided with a rigid arm, which, extended therefrom, has been secured to a yielding or spring stud.

I consider that a bolster provided with a yielding or spring arm is more serviceable for use and more eco; .oniical to manufacture than either of the classes of bolster-bearing just referred to.

The step of the spindle is designated by the letter h, and may be of any usual shape or construction.

A bolster having a substantially rigid or solid tube and attached spring arm or plate,

5 by which to secure the said sleeve or tube on [5 tion filed by me, Serial No. 205,874.

I claim- A sleeve-whirl spindle, combined with a r yielding bolster consisting of a solid or rigid sleeve interposed directly between the sleevewhirl and the pintle of the spindle and constituting the only lateral bearing for the spindle and surrounded only by the sleeve-whirl, and of a spring-arm attached to or forming part of the said sleeve, the said arm being adapted to be attached to a suitable base, thus permitting the said sleeve constituting the bearing portion of the bolster to move to a limited extent in substantially every direction with the spindle, substantially as described.

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