UNITED STATES PATENT OFFICE.

Specification of Letters Patent.

Patented Sept. 19, 1905.

Application filed October 28, 1904- Serial No. 230,306-

To all whom it natty concern:

Be it knownthat I, CHARLES B. YOUNG, a citizen of the United States, residing in Aurora, in the county of Kane and State of Illinois,have invented a new and useful Improvement in- J ournal-Bearings, of which the following is a specification.

My invention relates to journal-bearings for car-axles.

J ournal-bearings for car-axles as heretofore constructed have been made in various ways, either a brass back with a thin lead lining, a brass shell filled with babbitt, or a malleableiron back in combination with brass and Babbitt metal. In all these cases either the babbitt or brass formed the cylindrical surface to wear against the cylindrical surface of the axle, while the bearing-surface at the ends to wear against the shoulders or collars of the axle has invariably been of brass. The endthrust wear and friction is very con. 'derable, especially on railroads having numerous curves, and the friction and wear of the hardmetal axle against the hard-metal ends of the journal-bearings not only increases the draft of the train, but also materially diminishes the life and durability of the journal-bearings and journals of the axles. This wear due to end thrust shortens the life of a bearing considerably, as a bearing worn at the ends must be removed and put into scrap.

The object of my invention is to provide a journal-bearing which, while practically indestructible in its main body, may have the worn parts removed in a very simple manner.

My invention consists in the means I employ to practically accomplish this object or result-that is to say, it consists in the novel construction of parts and devices and in the novel combinations of parts and devices herein shown and described.

In the accompanying drawings, forming a part of this specification, Figure l is a central longitudinal section of a journal-bearing embodying my invention. Fig. 2 is a bottom view of the journal-brass before the babbitt or soft metal is applied. Fig. 3 is a cross-section on line 3 3 of Fig. 1, showing the brass without the Babbitt metal. Fig. 4 is a longitudinal section showing a modification in which the brass end segments are omitted.

In the drawings, A represents the brass, the same being preferably of steel or malleable iron. The steel or malleable iron or hardmetal brass A is provided with a chamber or recess a to receive the babbitt or soft-metal I wear-plate B, said chamber or recess having side walls a to confine the babbitt. The steel or" malleable iron or hard-metal brass A is preferably provided with end segments D, of brass, the same having integral dovetail tongues d, fitting in dovetail recesses of the brass to retain the brass segments in place. The end segments D are further provided with dovetail notches or recesses cl to receive the babbitt and permanently secure the babbittbearing tothe brass. The babbitt B also enters the dovetail notches a in the brass A and fills the interstices between the walls of said notches or recesses and the lugs cl on the brass end pieces D. In the modification illustrated in Fig. 4, where the brass end segments D are omitted, the dovetail recesses a in the brass A receive the babbitt and firmly secure the babbitt wear-plate in the brass. The babbitt or soft-metal wear-plate B has an integral end flange or shoulder 6, which embraces and covers the brass end piece D and forms an endthrust bearing for the collar or shoulder f of the axle-journal F, and at the opposite end the babbitt or soft-metal wear-plate B has a curved or rounded shoulder or integral flange b, which embraces the other brass end segment D and forms an end-thrust babbitt wearingsurface for the collar or shoulder f of the axle. The cast-iron or hard-metal brassA is provided at each end with transverse segmental shoulders or channels a to receive the brass end segments D. Where the brass end segments D are omitted, as in Fig. 4, the integral end-thrust bearing shoulders or flanges of the babbitt or soft-metal wear-plate fills the transverse segmental channels 0?.

I claim In a journal-bearing for car-axles, the combination with the brass having at the ends thereof transverse segmental channels or shoulders to receive end bearing-pieces, separate inserted end bearing-pieces fitting in said channels of the brass, and a babbitt or soft-metal wearplate having integral end bearing flanges or shoulders embracing and covering said inserted end pieces, said brass having dovetail recesses and said separate inserted segmental end pieces having integral tongues or lugs fitting in the recesses of the brass and said separate inserted end pieces having dovetail notches or recesses to receive the integral lugs of the babbitt or soft-metal wear-plate, substantially as specified.
