srxnnrin FOR S13INNINGr-1V1ACI-IIJSTIES.

To all whom it may concern:

Be it known that I, VARILD J RoBIDoU, a Citizen of the United States, :residing at Pawtucket, in the county of Providence and State of Rhode'lsland, have invented certain new and useful Improvements in Spindles for Spinning-Machines, of which the following is a specification.

This invention relates to an improvement in spindles for spinning machines.

The primary object of, the invention is to provide a construction in which the spindle may travel at a high rate of speed without undue friction, and in which the parts which are subjected to wear may be conveniently replaced.

A further object of the invention is to provide a construction in which the bolster maybe adjusted vertically within the outer casing.

A still further object of the-invention is to provide a structure in'which the oil is supplied to the spindle forpracticallythe entire length of its portion which" extends within the bolster. j

Another object of the invention is to provide means adjustable vertically of the bolster for supporting the base of the spindle.

For a full understanding of the invention, reference is to be had to'the following description and accompanying I drawings, in which: a Figure 1 is a side elevation; Fig. 2 isa vertical section; Fig. 3 is a section on the line 33 of Fig. 2; Fig. 1 is a section on the line 44of Fig. 2; Fig. 5' is a vertical section showing a slightly modified form;

and Fig. 6 is a section on the line 66 of Fig. 5.

Corresponding and like parts are referred to in the following description and indicated in all the views of the accompanying drawings by the same reference characters.

In the drawings, 10 designates the outer casing which is seated within the rail 11, being threaded as at 12 to receive the nut 13 by means of which it is supported against movement with respect to the rail, there being a washer 14 interposed between the nut and the rail. The casing 10 is enlarged above the rail to provide the oil compartment 15 formed with the sloping sidewall 16. Oil is supplied to said compartment Specification of Letters Patent.

through the spout 17 whichis, closed by the dofl'er guard 18 that engages over the whirl of the spindle.

The spindle 19 isof the usual constructron, being provided with the spindle pulley 20 which embraces the upper portion of the casing and bolster. A ring 20 is arranged on the spindle which prevents the oil from tends within the bolster, the lower terminal of the shank being formed with a threaded aperture 22 which receives the threaded passing upthrough the sleeve of the pulley. w The tapered shank 21 of the spindle exextension 23 of the step 241, the step thus being removable when worn.

The casing 10 is formed at its open' end with keyways 25 which receive keys 26 carried by the bolster-27. The bolster 27 is tapered and formed with a barrel to receive 1 .the spindle, being provided at its base with a threaded opening 28. A plug 29 is threaded in this opening, being provided with a head 30 by means ofwhich it may be adjusted with respect to the bolster. The

threaded member 29 is held against rotation.

by means of the set-screws-31 which are thread-ed transversely through the base, of the bolster. will not rotate the threaded member 29.

The end portion 31-o'f the plug 29 is concave to conform to the terminal of the step 2 1, the plug forming a seat for said step. It will be noted that by this construction,

Thus the spindle as it rotates both the plug and step may be renewed y The many. advantages of a construction of this character will beclearly apparent, as

,it will be noted that the portion of. the

spindle which is subjected to wear, as well as the portion of the bolster with which the spindle contacts, may be conveniently removed, and that the bearing plug of the bolster may be adjusted to compensate for wear.

In the form shown in Fig. 5, the bolster 34 is increased in diameter as, at 35 to form shoulders 36. The bolster 34, which is of substantially the same construction as the bolster shown in the preferred form, is reduced in diameter and is threaded as at 38. A ring 39 is arranged on the threaded portion of the bolster and adapted to contact with the shoulder 39. It will be noted by this construction that the ring may be adjusted longitudinally of the bolster, and that thus the bolster may be supported at difierent heights in the outer casing to compensate for wear and to allow for adjustment when the bolster is inserted within another casing in which the dofi'er guard is spaced to a greater or less extent from the end of the casing. The ring is normally held against rotation by set screws 40 which pass transversely through the same and contact with the bolster. 1

It will be noted that both the structure illustrated in Figs. 2 and 5 may be easily and economically manufactured, and that the various parts may be readily assembled. It will also be seen that the adjustable bearing illustrated in Fig. 2 is applicable to the form shown in Fig. 5, and that the two ad- 5 justing means coact to take up wear and to said casing and extending up beyond the enlarged portion thereof, the bore of said bolster being tapered and provided at inter- 5 vals with circumferentially extending relatively wide grooves forming oil containing chambers, one chamber communicating with the next adjacent chamber and the uppermost chamber communicating with the oil reservoir, a tapered spindle disposed within the bolster, and a pulley mounted on the spindle and extending down around the upper end of the casing and bolster.

2. A spindle bearing comprising an outer casing formed with an interior circumferentially extending shoulder, a bolster removably disposedwithin the outer casing and formed with a screw threaded portion, a ring 'adjustably mounted upon the screw threaded portion of the bolster and adapted to engage the shoulder of the casing, and a spindle disposed within the bolster and having a bearing thereon.

3. In a construction of the character described, a casing having an interior circumferential shoulder and formedabove the shoulder with a circumferentially extending oil containing chamber, a bolster disposed within the casing, said bolster having a reduced'portion screw threaded for a part of its length, a ring engaging said screw threads and adjustable longitudinally of the bolster, said ring resting upon the shoulder of the casing, the interior of the bolster being formed with a plurality of i circumferentially extending connected chambers, the uppermost of said chambers opening into the oil reservoir, and a spindle f rotatably mounted within the bolster.

In testimony whereof I aflix my signature in presence of two witnesses.
