Application filed January 13, 1905. Serial No. 240,961.

To all :whom it may concern:

Be it known that I, DANIEL M.

Wlrrson, journal.

by' which the rollers are loosely tied on the Before arranging and tying the a citizen of the United States residing at rollers y on the journal, the sleeve sections,

State of Oregon, have invented a new and useful Car Journal-Bearing,

followingis a specification, reference being I the same had to the accompanying drawing as constituting a part thereof.

My invention has for its object to prolong the life in good condition of journal bearings of car axles, and to this end consists of the devices combined with the journals and their bearings, for the purpose of obtaining the features hereinafter fully explained.

In the drawings, Figure 1 shows a longitudinal vertical section of one of the stand- 5 ard oriusual axle-bearings of a car, including my improvements; Fig. 2 is a cross section on a line AA. of Fig.1, but on a smaller scale than the latter, the journalbox however being omitted; Fig. 3 is a perspective of the two middle. sections of the sleeve by which the rollers are held in place on the journal; Fig. i is a detail on a large scale, showing a part of my improvement; and Fig. 5 1s a perspective of one of the rollers.

Referring now to the letters as designating the parts described: The axle-box (1., the wedge c, and the shouldered journal I) are respectively of the well known type. The bearing (Z is likewise made to answer its usual purpose, except that it does not directly ride or bear on the journal, but merely holds in place the interposed roller-bearing- To this end the bearing (l is made with a concavity in its inner face in which to re ceive my roller-bearing devices, and is further made with shoulders (l at its ends to engage with the shoulders of the journal of the axle and thereby hold my roller-bearing in place.

My roller-bearing comprises a box-like sleeve E, made of a number of sections, e, 0 c 6*, or agreater or lesser number, as deemed convenient; WVhen the sleeve E is put together it seryes to hold the rollers j on the journal, the" sleeve E-being made toeral groove k, in which to receive a Wire Z,

said retaining flanges respect to each other, the

the working of the hearing as a Multnomah and 6 should be put in place, and said sleeve sections will then serve to hold the rollers in of which the 1 place, as inserted, and facilitate the tying of by the wire. The ends l of the wire Z are so arranged as to protrude through an opening or cavity 71., provided therefor on the bottom of the sleeve E, as shown in Fig. l, by cutting away opposite portions g from the abutting faces of the two middle sections c", 6', thus facilitating the convenient removal of the wirel after the parts have bcenassembled. The cavity lt also is useful in discharging grit and other matter which may get into the bearing also to allow lubricant access to the rollers.

The end sections 6. a of the sleeve E are provided with flanges or ring-like retaining means f. The latter are represented in the drawings as consisting of removable endrings, but such construction is a more matter of convenience to which I do not confine my self.

To prevent thewear of the inner faces of of the end sections e, c, of the sleeve E, by j, l make the latter sufficiently shorter to allow the insertion of wear-rings i, which could be re laced when worn to any extent, and there y the bearing maintained in good condition. The wear-rings are preferably split to enablcthem to accommodate themselves the ends of the rollers to the inclosmg walls of said sleeve. sections. A

Further, I deem it preferable to make the wear-rings with a series of journal holes, and to adapt the ends of the rollers to be journalcd in said holes, whereby thc rollers are retaincdin a fixed relation or positioned with binding or interference of one with the other is prevented, and whole is ren dered much better.

I claimi 1. In a journal-bearing, the combination with theaxle-journal, of a box-like sleeve surrounding the journal and comprising a plurality of sections the end sections of which are provided with retaining means, wear-rings on the journal against the inner sides of said retainin "means of the sleeve and having journal ho es, rollers on the journal within the sleeve, the ends of which ing means of the rollers are journaled in said Wear-rings, and a bearing seated on said sleeve and arranged to hold the same in place on the axle-journal.

2. A journal bearing comprising a shonl dered axle-jcmrnal, a box-like sleeve, surrounding the journal, and comprising a plurality of sections, the end-sections of which are provided with retaining means, and the middle two sections havmg portions of the opposed faces cut away, at the bottom, for the purpose described, wear-rings on the journal against the inner sides of said retainslew e and having journalholes, rollers on the journal Within the sleeve, the ends of which rollers are journaled in said Wear-rings, and a bearing seated on said sleeve and arranged to hold the latter in place between the shoulders of the axlejournal.

In a journal bearing, the combination with an axle-journal, of a box-like sleeve snrroundil'lg the journal and comprising a plurality of sections, the end sections of I which are provided with retaining. means, and the middle two sections having portions of the op msed .t'aces cut away at the bottom, f for the purpose described, \vea1.'-rings on the I journal against the inner sides of said retain- I ing means of the sleeves, and having j ournalholes, rollers on the journal within the sleeve, 1 the ends of which rollers are journaled in said wear-rings, and a bearing seated on said .sleeve and arranged to hold the latter in place on the axle-journal. I In testimony whereof, I have hereunto affixed my sigl'iature in the presence of two witnesses, this 10th day of October, 1904.
