JOHNIE'. OCONNOR, or CHICAGO, ILLINOIS, ASSIGNOR T0 WILLIAM H. MINER, or

SIDE BEARING.
To all whom it may concern:
Be it known that I, J OHN'F. OConnon, a citizen of the United States, residing at Chicago, in the county of Cook and State'of Illinois, have invented a certain newand useful Improvement in 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 side bearings.
One object of the invention is to provide a novel side bearing wherein is employed a roller of substantially conical form rotatable about an axis inclined with respect to the two bolsters between which it is interposed.
Another and more specific object of the invention is to provide a roller side bearing of the type above indicated, having means for lubricating the same to minimize friction.
In the drawing forming a part of this s ecification, Figure 1 is an end elevation of portions of a body and truck bolster of a car showing my improvements in connection therewith. Fig. 2 is a vertical sectional view of the improved side bearing and taken substantially on the line 2-2 of Fig. 3. And Fig. 3 is a top plan view of the improved side bearing.
In said drawing, 10 denotes a body bolster and 11 a truck bolster pivotally connected thereto in the usual manner, the body bolster being provided with a striking plate 12 with which cooperates a roller side hearing designated generally by the reference A.
The improved side bearing A, as shown, comprises a base casting B having end flanges l313 by which it is riveted or otherwise secured to the truck bolster, said casting B having a centrally located upstanding enlargement 14 provided with a cylindrical bore or recess 15, the axis of which extends at 45 degrees to the plane of the top face of the truck bolster, the axis being in a vertical plane extending through the pivotal connection between the bolsters, the axis being also inclined toward the car center bearing. Rotata'bly mounted within said bore or recess 15 is the journal or axle 16 of the roller C. The latter is formed integrally with the upper end of the journal 16 and is of substantially truncated conical form, as clearly indicated in Fig. 2. The
Specification of Letters Patent.
Patented Jan.1,1918.
' Application filed July 15,1916. Seria1No .109,42 1.
bearing surfaces are preferably slightly convexed as indicated at 17. The roller C is maintained in proper position by means of a cotter 18 which extends through the enlargement 14: on the base casting and fits within an annular groove 19 formed around the journal 16. The roller C is provided with an axial opening 119 interiorly threaded at its outer end to receive a threaded plug 20. It will also be noticed that the journal 16 does not completely fill the bore 15 whereby I am-enabled to maintain a supply of lubricating oil 21.
It will be understood that the bearing surface of the roller C is so designed that the upper portion thereof will lie substantially horizontally as indicated at Fig. 2 or, in other words, the angle between the surface of the roller and its axis is substantially 45 degrees. By the arrangement shown, oil may be maintained within the bearing to thereby minimize friction and the parts are so arranged that practically no dust or dirt can enter the bearing as is clear from an inspection of Fig. 2.
Although I have herein shown and de scribed what I now consider the preferred embodiment of my invention, the same is merely illustrative and I contemplate all changes and modifications coming within the scope of the claims appended hereto.
I claim:
1. In a side bearing, the combination with a horizontally disposed base member adapted to be secured to a truck bolster, said base member having a journal bearing formed therein inclined at 45 degrees to the vertical, of a conical roller having a journal mounted in said bearing, the load being transmitted to the base member through the journal.
2. A roller side bearing adapted to be interposed between two substantially parallel surfaces, said bearing comprising a base member, a roller mounted therein, the roller a base member having a journal bearing formed thereln, said bearing being lnohned, of a roller of conical form having a ournal mounted in said bearing, the roller being centrally perforated whereby communlcaa retaining casting having an inclined journal bearing formed therein, of an anti-frietion roller havlng a bear ng portion of conioa' l' formed bearing-portion, the load applied 15 to the anti-friction roller being transmltted ,to the retaining member through the journal.
In Witness that I claim the foregoing I havehereunto subscribed my name thislSth day'ofJu'ly 1916. e
