PATENT OFFICEO RICHARD BEDDALL, OF MALDEN, MASSACHUSETTS.

lJOURNAL- BEARING.

SPECIPICATION forming part of Letters Patent No. 314,989. dated April 7, 1885.

Application filed January 26, 1885.

To all whom it may concern.-

Be it known that BICI-IARD BEDDALL, of Malden, in the county of Middlesex, State of Massachusetts, have invented a certain new and useful Improvement in J ournal-Bearings, of which the following is a description sufliciently full, clear, and exact to enable any person skilled in the art or science to which said invention appertains to make and use the same, reference being had to the accompanying drawings, forming a part of this specification, in Which- Figure l is a vertical longitudinal section of my improved journal-bearing; Fig. 2, a bottom or interior view of the same; Fig. 3, a like view with the auxiliary bearing removed 5 Fig. 4, a plan view of the auxiliary bearing detached; Fig. 5, a vertical transverse section taken on the dotted line :1: x in Fig. 2, and Fig. 6 alike view taken on the dotted line y y in Fig. 2.

Likeletters of reference indicate corresponding parts in the different gures ofthe drawings.

My invention relates more especially to that class ofjournal-bearings which are designed for use with car-axles, locomotive-axles, 85o., although well adapted for journals of nearly every description; and it consists in a novel construction and arrangement of the parts, as hereinafter more fully set forth and claimed, by which a more effect-ive and otherwise desirable article of this character is produced than is now in ordinary use.

The nature and operation of the improvement will be readily understood by all conversant with such matters from the following explanation.

In the drawings, A represents the body of the bearing, or bearing-proper, and B the auxiliary bearing. The body ofthe bearing is composed of composition or other suitable metal, and is of the ordinary form and construction, except as hereinafter specified. The body is provided with a depression, O, extending its entire length to receive the auxiliary bearing or slide B. A series of anges, m, project inwardly from either side of the depression C, and in the bottom of said depression there are two grooves, t t, arranged in parallelism' and connected by the transverse grooves r. The

auxiliary bearing or slide B is preferably com- (No model.)

pression C, its ianges d passing under the Iianges m. Babbitt or other suitable metal is then melted and poured into the spaces between the edges of the 'auxiliary bearing and the body, the melted metal a flowing into and filling the spaces f between the Iianges m d,there by securely locking the auxiliary bearing into the body in a manner which will be readily obvious without a more explicit description.

The metal or composition composing the body A is preferably slightly harder than the metal a and the metal a slightly harder than that of which the auxiliary bearing B is composed. The bearing B and metal a also project slightly beyond the bearing-surface of the body A, so that as the bearing is used the bearingsurfaces of the parts c B soon wear down to a plane with the bearing-surface of the body, and thereby fit or adjust themselves more perfectly to the journal than would otherwise be possible. Oil ducts or holes fi lead from the bearing-surface or inner face of the bearing to the grooves Z, and in lubricating the journal the oil passes through the hole b into the reservoir formed by the grooves t r, filling said reservoir, and from thence along the grooves Z and through the ducts z' to the journal.

It will be obvious that the flow of oil through the duct or hole b may be governed by any suitable appliances for that purpose; also, that a strainer may be used in connection with the oil-cup, to prevent dirt, gravel, &c., from being carried into the reservoir within the bear- Ing.

rlhe holes t are formed by cutting vertical grooves in the edges of the auxiliary bearing B at the ends of the grooves Z, as seen in Fig. 4, and filling them with plumbago or some other suitable poring substance, the plumbago being removed after' the metal fastenings a have been cast into the spaces f, as described.

The object in making the metal a slightly IOO harder than the bearing B is to enable it to ngrooves tr, and oil-duct b, the auxiliary bear hold the parts A B firmly in position, and also ing B, provided with bhe flanges d, grooves Z, because of its narrow bearing-surface, which and holes 13, and the metallic lastenings a a, would render it liable tvo Wear away more rapconstructed, combined, and arranged 'to oper- 5v idly than lshe auxiliary bearing. ate substantially as set; forth.

I CIfIaLggg-thus explained my invention, what RICHARD BEDDALL.

The improved journal-bearing herein de- Vibnesses: scribed, the same consisting of the body A, C. A. SHAW,
