JOURNAL-BEARING.

SPECIFICATION forming part of Letters Patent No. 226,907, dated April 27, 1880.

Application filed March 1, 1880. (ModeL) To all whom it may concern:

Be it known that I, REUBEN WV. DREW, of Dayton, in the county of Montgomery and State of Ohio, have-invented certain new and useful Improvements in J ournal-Bearings; and I do hereby declare that the following is a full, clear, and exact description of the invention, which will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, which form a part of this specification.

Figure 1 is a perspective view. Fig. 2 is a longitudinal sectional view, and Fig. 3 is a cross-section.

Corresponding parts in the several figures are denoted by like letters of reference.

This invention relates to car-axle boxes; and it consists in certain improvements in the construction of the same, which will be hereinafter more fully described, and particularly pointed out in the claim.

In the drawings, A represents a metallic shell, of the shape of an ordinary car-axle box, and provided upon its inner corners with longitudinal ribs or flanges B B, which said flanges are provided with longitudinal perforations P P. One end, 0, of the box is loose, but capable of being secured firmly in position by bolts D D passing through the perforations P P and nuts E E. The flanges B B, it will be observed, project toward each other, so as to form practically a dovetailed recess in the bottom of the shell. F F are pieces of rawhide, which are of such size and shape as "to fit nicely in the shell, into which they are inserted from the end, the end piece, 0, being The lower edges of the rawhide strips are segmental, so as to fit the spindle of the axle for which they are to form a hearing. The box being filled, the pieces of rawhide are compressed therein by hydraulic or other pressure, thus forming a compact mass of great density, which makes an excel- .lent journal-bearing. The end piece, 0, is now secured in position, and the bearing is finally trimmed and smoothed, and the box is then ready for use.

The flanges B B, it will be seen, serve a twofold purpose: first, they extend toward each other, so as to form a dovetailed recess, by which the pieces of rawhide are prevented from dropping out of the box; second, they are provided with longitudinal perforations to receive the bolts by which the end piece, 0, which holds the rawhide bearing-pieces after being compressed, is secured. When the bolts are passed through perforations in the pieces of rawhide the latter cannot well be compressed, because heavy pressure would partially obliterate the bolt-openings, so as to render them practically useless. Besides, the expense for time, labor, and material in the construction of the boxes would be increased, while by my invention a simple, cheap, and in every respect desirable journal-bearing is produced.

Having thus described my invention, I claim and desire to secure by Letters Patent of the United States- The herein-described improved axle-box, consisting of the metallic shell A, having flanges B B projecting toward each other, and provided with longitudinal perforations P I movable end piece, G, bolts D D, nuts E, and the rawhide bearing-pieces F F, all combined and operating substantially as and for the purpose herein set forth.

In testimony that I claim the foregoing as my own I have hereto affixed my signature in presence of two witnesses.

REUBEN W. DREW.
