WILLIAM.- A. BOCK, OF CHICAGO, ILLINOIS, AS SIGliTOR TO WILLIAM H. MINER, OF GHAZY, NEW YORK.
ROLLER SIDE BEARING.
To all whomit may concern:
Be it known that I WrLLIAM A. 13001:, a citizen oi the United tates, residing at Chicago, in the county o1 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 bearing more particularly adapted for railroad car service, wherein the anti-friction roller is mounted in a rockable cradle supported and retained in a novel manner on a base casting.
The invention furthermore consists in the improvements in the parts and devices and in the novel combinations ofthe parts and devices herein shown, described or claimed.
In the drawings forming a part of this specification, Figure 1 is an elevational view of the parts of the truck and body bolsters of a railway car showing my improvements in connection therewith. Fig. 2 is a top plan view of the end portion of the truck bolster, and showing my improved bearing. Fig. 3 is an enlarged sectional view of the side bearing taken substantially on the line 33 of Fig. 2. And Fig. 4 is. a view similar to Fig. 3, but taken at right angles thereto and substantially on theline H of Fig. 2.
In said drawing, 10 denotes the body bolster which is swiveled to the truck bolster 11 in the usual manner, and between which is interposed my improved side bearing designated generally by the reference A, as shown. The side bearing A comprises a base casting 12, having flanges by which it is adapted to be riveted to the truck bolster 11, as clearly indicated in the drawing. Rockably mounted on the base casting 12 is a cradle 18, and rotatable in the cradle is an anti-friction roller 14:.
The rockable bearing between the base casting and cradle 13 is formed by a pair of convexly curved bosses 1515 formed on the upper face of the base casting 12, with which cooperate corresponding concave recesses 16-46 formed on the under side of the cradle 13. As will be understood, the bosses 15 and recesses 16 are located centrally of the Specification of Letters Patent.

Application filed October 18, 1915. Serial No. 56,444.
cradle and basecasting, transversely thereof.
At the sides of each boss or bearing 15 on the base casting 12 are horizontal ledges or shoulders 17-17, with which cooperate corresponding shoulders 18 on the under-side of the cradle 13, to thereby limit the amount of rocking movement of the cradle To retain the cradle on the base casting and also to retain the cradle in proper position after it has been once adjusted on any particular car, I have provided a pair of bolts -1919, which extend through recesses 20 formed in extensions '21 at the ends of the cradle 13, and through recesses 22 formed in upstanding projections 23 at the ends of the base casting 12. The recesses in the cradle are enlarged at their upper ends, as
- indicated at 24, to thereby receive the heads or the bolts and also springs 25 which are confined between the heads of the bolts and the shoulders formed at the bottoms of the enlarged portions 2 101 the recesses. On the under side of the base casting 12, and communicating with the recesses or perforations 2222 in the latter, are enlarged recesses or sockets 26 to receive the rounded nuts screwed onto the ends of the bolts 19. As most clearly indicated in Fig. 3 at 28, the recesses 22 are tapered in planes transverse of the base casting in order to permit the bolts-19 to rock with the cradle.
The cradle 13 is provided with a centrally enlarged recess 29, open at the top and bottom but with the topopening somewhat re- I stricted, said recess having mounted therewithin the anti-friction roller. 14:. The roller 14 is carried on a journal or axle 29, the ends thereof being mounted in the side walls 30-30 of the cradle. In order to prevent the axle 29 from rotating, one end thereof is chamfered, as indicated by the dotted line 31 in Fig. 4:. To prevent the axle 29 from becoming accidentally displaced, I have provided a spring plate 32 which has the ends of the same snapped into position in recesses formed in bosses 33 on one side of the cradle 30 and in order to minimize the wear between the roller and the axle 29, there is a sleeve 34: of any suitable metal interposed therebetween.
From the preceding description in connection with the drawing, it will be seen that the axis of the roller 14: is at right angles to the axis about which the cradle the angular relation of the opposed faces" of the bolsters. In addition, it will be noted that when the cradle has been tilted, the
As will be understood by those skilled in the art, various changes and modifications may be made in the details of construction and arrangement ofthe parts without departing from the spirit of the invention,.and I contemplate all such changes and modifications as come within the scope of the claims appended hereto.
I claim:
1 In a device of the character described, the combination with a base casting, and a rollercarrying cradle rockably mounted thereon, of spring means for automatically retaining the cradle in any adjusted position. I
2. In an anti-friction bearingof the character described, the combination with a base casting; of a cradle mounted on said base casting, said cradle being centrally recessed to thereby provide spaced parallel side walls; and an anti-friction roller located within said recess and rotatably supported from said side walls, said base casting and cradle being provided with cooperating means to permit the cradle to rock on the base casting, said means comprising convexly shaped bosses on one of said members and correspondingly concavely shaped recesses on the other of said members, the axes of said convexly shaped bosses and conoavely shaped recesses extending transverse to the axis of the roller.
3. In an anti-friction bearing of the character described, the combination with a base casting having Lip-standing bosses at its ends, said bosses having convex surfaces; of a cradle, said cradle having concave recesses at its ends cooperating with said convex bosses, the cradle being centrally recessed; and an a11ti-iriction roller journaled within said recess of the cradle and with the periphery thereof extending above the top surface of the cradlef f 4. In a device of the character described, the combination with a base casting and a rollercarrying cradle rockably mounted thereon, of bolts extending through portions of said cradle and basejcasting to thereby retain the two parts in proper relation, and springs interposed between the ends of said bolts and one of-said members whereby to retain the cradle in any adjusted position. i i V 5. In a'device of the character described, the combination with a base casting and a rollercarrying cradle rockably mounted thereon, ofbolts extended vertically through alined recesses in the cradle and base casting, said bolts retaining the cradle in operative position on the base casting.
'6. In a device of the character described, v
the combination with a base casting and a roller carrying cradle, said casting and cradle being provided with cooperating means to permit the cradle to rock on the casting, said means comprising bosses having convex surfaces on one of said members i and recesses having concave surfaces on the other of said members, of spring means for automatically retaining the cradle in position after the same has been adjusted.
In witness that I claim the foregoing I have hereunto subscribed my name this 9th day of Sept, 1915. M
