SPINNING-SFlNDLE..

SPECIFICATION forming part of Letters Patent No. 776,122, dated November 29, 1904.

Application led August l, 1904.

To all whom llt may concern.-

Be it known that I, Geenen Oris DRArEn, a citizen of the United States, and a resident of Hopedale, county of Worcester, State of Massachusetts, have invented an Improvement in Spinning-Spindles, of which the following description, in connection with the accompanying drawings, is a speciiication, like characters on the drawings representing' like parts.

This invention has for its object the production of a novel bearing for spinning-spindles of the type wherein the tapering pintle of the spindle is supported in the correspondingly-tapered bore of a bolster, suitably sustained in a bolster-case adapted to be secured to the spindle-rail.

ln my present invention the bolster is maintained under the control of a spring under tension, permitting the spindle to run without vibration or jarring at very high speeds and with unbalanced loads. Means are also provided for regulating or adjusting the iit of the spindle-pintle inthe bolster and for varying' the tension of the bolster-controlling spring.

The various novel features of my invention as contained in one practical embodiment thereof will be fully described in the subjoined specification and particularly pointed out in the following claims.

Figure 1 is a vertical sectionalview and part elevation of a spinning-spindle embodying one form of my invention. Figs. 2 and 3 are side elevations of the bolster, connected spindle-step, and the suspension connection for the bolster removed from the bolster-case, the parts in Fig. 3 being turned one-quarter around from the position shown in Fig. 2 and with the suspension connection partly broken out and in section; and Fig. 1 is a detail in section of the bottom of the bolster case viewed at right angles to Fig. 1.

Referring to Fig. 1, the spindle S, having' a tapering pintle S and provided with a sleevewhirl W, the bolster-case B, adapted to be clamped as usual to the spindle-rail by a nut BX, and the downhold w for the whirl may be and are all substantially of well-known construction. The upturned end b of the bolster-case is provided with one or more notches Serial No- 2l8,992. KNO model.)

, and surrounding the lower part of such up turned end is a circular wall Z2, and the chamber formed thereby communicates at 3 with the oil-reservoir b1, which, as will be noted, is quite low down.

In the present embodiment of my invention the oil has a tendency to run over the top of the bolster, and when it runs down outside the upper end of the bolster-case it falls within the wall or guard L and is returned through the opening b3 to the reservoir and the interior of the bolster-case. The whirl is provided with a petticoat w, which extends down within and below the top of the guard b2, so that the oil cannot be thrown outward.

IThe bolster' 1, having a tapering bore 2 to receive the spindle-pintle and provided with oil-holes 3, has a coarse screw-thread 4 formed on its upper end, while a longitudinal slot 5 is cut therein for a purpose to be described. A spiral groove o' is cut on the lower end of the bolster to `receive the coils at the upper end of a spiral spring 7, the coils tightly gripping the bolster and permitting the latter to be screwed thereinto, but preventing its rotation in the reverse direction. A spindle-step S is loosely inserted within the lower end of the spring and attached thereto by inserting the inturned extremity 9 of the spring into a transverse hole 10 in the step. The foot 11 of the step is enlarged and recessed transversely at 12 with a notch 13 in the lower part at right angles to the recess, (see Fig. 1,) the foot of the step being recessed and notched to cooperate with a pin 14, (see Figs. 1 and 11,) projecting inward from the side wall of the bolster-case near its bottom for a purpose to be described.

A suspension connection for the bolster is shown as an internally-threaded collar 15, adapted to receive with a rather loose lit the threaded portion i of the bolster, the collar having depending lockingdugs 16, Figs. l, Q, and 3, to enter the notches b when the collar is seated on the top of the part b of the bolster-case, as in Fig. 1. The bolster is thus suspended within the bolster-case, and relative rotation of the bolster and collar will effect vertical adjustment of the bolster.

- bolster.

In order to prevent rotation of the bolster in the suspension connection, the latter is provided with a notch 17 to receive a depending lug 18 on a locking-washer 19, adapted to rest upon the collar 15, the lug being inturned to also enter the slot 5 in the bolster, as shown in Fig. 3. By this arrangement the bolster and the suspension connection 15 are locked together, and the lugs 16 lock all from rotation in the bolster-case.

To assemble the parts, the locking-washer is removed and the bolster is turned inthe connection 15 suiciently to permit the recess 12 in the foot of the spindle-step to receive the pin 14 when the bolster and connected step are pushed down into the bolster-case.

In Fig. 4 the foot of the step is shown as about to pass down to its lowest position, the notch 13 permitting the lower part of the foot to pass below the pin 14. The bolster and step are then turned bodily through onequarter of a revolution, so that the pin 14 will lie within the recess 12 and across or at right angles to the notch 13, thereby holding the step from further rotation. The spring 7 is now stretched or put Linder tension by screwing the suspension connection 15 down upon the bolster, thereby raising the latter until the position of the bolster with relation to the step has determined a proper lit of the blade in the When the desired fit is secured, the lugs 16 are dropped into the locking-notches Z2 and the locking-washer 19 is applied, locking the bolster and connection from rotation. If now it is found necessary to increase the spring tension, it is attained by rotating the bolster and connection 15 while they are locked together, for thereby the spiral groove 6 of the bolster is screwed farther into the spring 7 stretching it accordingly as its lower end is held by the spindle-step locked in the bottom of the bolster-case.

It will be manifest that there can be no leal;- age of oil from the bottom of the bolster-case, as the latter is closed.

The adjustment of the parts either to vary the fit of the spindle-pintle in the bolster or to increase the tension of the spring must obviously be effected when the spindle is removed from the bolster.

Having fully described my invention, what I claim as new, and desire to secure by Letters Patent, is

1. In a spindle-bearing, in combination, a bolster-case, a bolster therein having a tapering bore to receive the pintle of the spindle,

va spring under tension attached to and controlling the bolster, means to vertically move the bolster to vary the tit of the spindle-pintle therein, and separate means to adjust the tension of the spring.

2. In a spindle-bearing, in combination, a bolster-case, a bolster therein having a tapering bore to receive the pintle of the spindle,

l a suspension connection between the bolster and bolster-case, the bolster being longitudinally movable relatively to said connection to change the lit of the spindle-pintle, and means independent of the bolster-case to lock the bolster and suspension connection together and prevent relative movement thereof.

3. In a spindle-bearing, in combination, a bolster-case, a bolster therein having a tapering bore to receive the pintle of the spindle, a spring und er tension connected with the lower end of and controlling the bolster, means to adjust the tension of the spring by or through rotation of the bolster relatively to the spring, and separate means to vertically adjust the bolster to change the lit of the spindle-pintle therein.

4. In a spindle-bearing, in combination, a bolster-case, a bolster therein having' a tapering bore to receive the pintle of the spindle, a spring under tension connected with the lower end ot' and controlling the bolster, a suspension connection between the latter and the bolster-case, simultaneous rotation of the bolster and connection adjusting the tension of the spring, relative rotation of said parts vertically adjusting the bolster to change the iit of the spindle-pintle therein, and a device to lock the bolster and suspension connection together.
