WITNESS JOHN F. OCONNOR, OF CHICAGO, ILLINOIS, ASSIGNOR 1.0 WILLIAM H. MINER, 0F CHAZY, NEI/V YORK.

ROLLER. SIDE BEARING.

Application led March 1, 1916.

To zZZ whom it may concern:

Be it known that I. JOI-IN F. CConnon, a citizen of the United States, residing at Chicago, in the county of Cook and State of Illinois, have invented a. certain new and useful Improvement in Roller Side Bearings, of which the following is a full, clear, concise, and exact description, reference being had to the accompanying drawings, forming a part of this specification.

This invention relates to improvements in roller side bearings.

The object of the invention is to provide a roller Side bea ring, more particularly adapted for use on railroad cars, and which is composed of few parts simply arranged, which may be cheaply manufactured, easily applied and repaired, which permits of a wide range of travel. which is self centering and also anti-rattling.

In the drawing forming a part of this specification, Figure 1 is an elevational view of portions of two holsters of a railway car, showing my improvements in connection therewith. Fig. 2 is a top plan view of the truck bolster showing my roller side bearing applied thereon. And Figs. 3 and 4 are enlarged sectional views taken respectively on the lines 3-3 of Fig. 2 and elf-4 of Fig. 3.

In said drawing, 10 denotes a truck bolster and 11 a body bolster swiveled at the center in the usual manner. The body bolster is provided with a striking plate 12, and the truck bolster has my improved roller side bearin A applied thereto.

As shown in the drawing, the improved side bearing A comprises a casting B, roller C and spring axle D. rIhe casting B has a bottom plate 13, outer vertical wall 14 and end limiting walls 15*15. The wall 14, at the center thereof, is provided with an enlargement 1G having a longitudinally extending slot 17 therein, said slot 17 having extending therein the end 18 of the spring rod axle D. For increased durability, the casting B is provided with a hardened insert plate 19 on which the roller C bears when in operation.

rlhe spring axle D is preferably formed Speccation of Letters Patent.

from a rod of spring steel having an axle portion proper 20, shouldered vertically ex tending portion 21 and horizontal arm 22, the latter at its inner end being Hattencd as indicated at and riveted to the truck bolster. The spring axle 22 is preferably so bent, as indicated by the dotted lines in Fig. 1, that when it is riveted to the truck bolster, the roller C will be normally held out of engagement with the wear plate 19, thereby minimizing tendency of the roller to rattle. In operation, as the ends of the bolsters approach each other, the roller C will be forced down on its bearing plate 19 and will then roll in accordance with the relative movement between the holsters. The limit of movement of the roller is determined by the end walls 15-15 of the asting ll and it is obvious that upon separation of the bolsters, the roller C will automatically be returned to central normal position due to the inherent elasticity in the rod l).

From the preceding description, it will be seen that the roller bearing which I have provided is extremely simple, consists of few parts, the spring rod axle may be easily and cheaply renewed and furthermore. the roller C may be made substantially solid. an iinportant consideration in devices of this class where the pressure often becomes very lgreat.

As shown, the roller C need only7 be cored or recessed to receive the relatively small diameter axle rod. It is also apparent that the roller C is permitted suthcient play inwardly and outwardly relatively to the center of the trucks to accommodate itself to the proper positions while being actuated, the wall 1t limiting the outward movement of the roller C and the shouldered portion 21 of the rod limiting its inward movement.

I claim:

1. In a roller side bearing, the combination with a bolster. of a roller, a spring axle on which said roller is mounted, the latter being so formed as to normally support said roller out of engagement with any part of the bolster.

2. In a roller side bearing, the combination with a bolster, a casting secured to said bolster, and an anti-friction roller bodily moyably mounted in said casting, of a spring ed on Jthe free end of said rod and normally rod axle on which said rollei1 is mounted, supported thereby.

said rod axle having` its inner end rigidly 1n Witness that I claim the foregoing I secured to the bolster and provided interhave hereunto subscribed my name this 28th l0 mediate its ends with a bent section to form day of Feb., 1916.

a shoulder, the roller being rotatably mount- Y JOHN F. OCONNOR.
