This invention; relates to improvements in the construction of bearings for railroad-car axles, or other journals, and consists in forming a brass or other metal attachment, in connection with acast-iron box or shell, insuch manner as to hold securely in placea-s hereinafter described.

A represents an outside cast-iron she or box, on the inner sident? 'Whicllare tted section -of Babbitmetal bearings, B B, which set in their bed, and are held in place by pins, Yt a, that pass. through holes, c o, in the shell A. y

A brass or iron frame, G, is made to .t around the outer sides of the Babbit-metal bearings B B, having sections of Babbit or other soft metal for the bearings,

a centre-bar, b, running longitudinally, with the box betweenthem, and secured to the shell A by pins d d, on the centre-bar b, which pass through holes, e e, in the shell, and are to be riveted on the outside, or may be threaded and held with nuts. l

To prevent endwise and lateral movement ot' the frame C, and keep it firmly iu place, the ends are dove- .tailed in dovetail-recesses, h h, in the cast-ironshell A.y

The outer projectingend ofthe shell A is strengthcned to prevent it from breaking off by excessive pressure, to which railroad-car boxes are exposed, by casting lips or corner-pieces, k It, connecting the sides and top of the shell.

Having thus described my invention, A

.I claim as new, and desire to seeure by Letters Patentl. The frame O, having aoentre-bar, b, secured to.

the shell A by pins d d, and dovetailed ends in the recesses h It, in combination with the soft-metal bearings B B, separated by the single longitudinal barb', substantially described.
