ANTI-FRICTION JOURNAL-BOX.

SPECIFICATION forming part of Letters Patent No. 354,941, dated December 28, 1886. Applicationv filed July 10, 1886. Serial No. 207,691. (No model.)

To @ZZ whom it may concern:

Be it known that I, WILLIAM S. SHARPNEOK, a citizen of the United States, residing at Denver, in the county of Arapahoe and State of Colorado, have invented certain new and useful Improvements in AntiFriction Journal-v Boxes, of which the following is a specification, reference being had therein to the accompanying drawings, in Which- Figure lis a central longitudinal section, and Fig. 2 a transverse section through the line :v x in Fig. 1.

This improvement relates to that class of anti-frietionjournal-boxes in which tapering rollers areemployed to reduce the friction; and the invention consists in the peculiar combination and the construction and arrangement of parts hereinafter more particularly described, and then detined in the claims.

Referring now to the details ofthe drawings, A represents the casing, which may be of any suitable form in the center, and having at or near each end a portion, a, that is slightly aring outward from the center, .as shown in Fig. l.

Inclosed within the central portion of the casing, and loosely surrounding the shaft B,

is a hollow ring, C, in which is secured, by screwing or otherwise, a series ot' stufngboxes, D, in each of which is journaled a shaft, E, having a flange, e, at onerend to retain it in its bearings, and a roller, F, at the other end, which roller runs between the flaring portion a of the casing A and a tapering adjustable roller or collar, G, held on the shaft B by a setscrew, H.

The rollers F may be made of any suitable material; but I prefer that they shall be made' of compressed paper with a flange or head, f, of metal at each side, and the whole held together and on the shaft by means of a nut, I, screwed on the outer end of the shaft E, which is threaded for this purpose.

I have shown and prefer to use six shafts E and rollers F on each side of the ring C, but do not limit myself to this number, as this may be varied by changing the proportions of the parts. l

Each stuffing-box is provided with a cap and packing in the usual manner of constructing a stuffing-box, and each of said stungboxes should be of proper length to form a suitable bearing for the shaft running in the same, so as to keep the same in its proper relative position.

Any convenient Inode of filling the hollow ring with lubricant may be employed-such, for instance, as an opening with a screw-cap, as lshown at J, to which access may be had through an opening, K, formed in` the top of the casing.

By this construction an anti-friction journal-box may be made in which each roller is retained in its proper relative position by a guide that will only require a supply of lubrieating material at very long intervals, and one in which any wear that may occur may be easily taken up, or any necessary adjustment required in assembing the parts may be readily made, by simply moving one of the collars G toward the centralring, C, and securing it by means of the set-screw shown, or by any other convenient means.

What I claim as new isl. The combination, with the shaft B and casing A, of a hollow ring adapted to be filled with and hold a liquid lubricant, and a series of friction-rollers having their shafts running in said hollow ring, substantially as described.

2. The combination, with the`conical rollers F and with the casing A, having a flaring end, a, of a shaft, B, having a tapering collar constructed to be adjusted lengthwise of the shaft, substantially as described.

3. Thel combination, with the casing A and the shaft B, of a hollow ring, C, provided with a series of stuftlng-boxes forming bearings for the shafts of the rollers, substantially as described.

4. The combination of a casing, A, having a daring opening at each end, of a series of rollers, F, working therein, the shaft B,'and

the tapering collars secured thereon, with the ring C, provided with a series of stuffingboxes forming bearings for the shafts of the rollers F, all constructed substantially as described. l

In testimony whereof I affix my signature, in presence of two witnesses, this 28th day of June, 1886.

WILLIAM S. SHABPNEGK.
