JOURNAL-BEARING.

SPECIFICATION forming part of Letters Patent No. 299,109, dated May 27, 1884. Application filed September 11, 1883. (No model.)

To aZZ whom it may concern.-

Be it known that I, CHARLES F. BRIGHAM, of Worcester, in the county of WVorcester and State of Massachusetts, have invented a new and useful Improved Journal Bearing, of which the following is a specification.

This invention relates to journal-bearings for the axles of cars, 8m. and the object sought is to produce a journal-bearing which is composed of a combination of paper-pulp and asbestus chemically treated, as hereinafter described, and provided with a metal lining on its journal side, thus forming a journal-bearing which is capable of great wear without doing damage to the journal, and one that can be constructed at much less cost than the journal-bearings now in use.

In the accompanyingdrawings, forming part of this specification, Figure 1 illustrates a perspective view of my improved journalbearing, showing the manner in which I preferably arrange the parts; and Fig. 2 representsatransverse section through the line a: m, Fig. 1..

The principal portion of my improved hear ing, which forms the body A, is made of paper-pulp and asbestus, as will be hereinafter explained. {Ihe side next to the journal is provided with a perforated sheet of metal (shown at B, Figs. 1 and 2) to give the requisite bearingsurface.

These bearings can be made of paper-pulp alone; but there is apossibility of its becoming heated, when it would either burst or break, and thus be useless. In order to remedy this evil, I usually add enough asbestus to destroy the heating propensity of the paper, so that it will usually run cool. The paper-pulp and asbestus are chemically treated with the oxide and chloride of magnesium, as follows: I usually mix equal parts (by weight) of asbestus and paper-pulp with oxide of magnesium, and when thoroughly incorporated temper with chloride of magnesium to the proper consistency for molding. The perforated metal lining Bis used to give the requisite bearingsurface at the start.

Having thus described my invention, what I claim, and desire to secure by Letters Patent, 1s-

1. A journal-bearing composed of asbestus and paper-pulp treated with oxide and chloride of magnesium, in the manner and for the purpose herein specified.

2. A journal-bearing composed. of asbestus and paper-pulp treated with oxide and chloride of magnesium, as herein described, and provided with a perforated metal lining on its journal side, all as described, and for the purpose set forth.

In testimony that I claim the foregoing improved journal-bearing, as above described, I have hereunto set my hand this 9th day of May, 1883.

CHARLES F. BRIGHAM.
