' slim BEARILl'G. FOR RAILWAY-CARS.

Specification of Letters Patent.

Application filed October 22, 1914. Serial No. 868,013.

To all whom z't'may concern:

Be it known that I, CALVIN B.'PA'rcn, a

citizen of'the United States, residing at (ilenellyn, in the county of Du Page and Stateof Illinois, have invented a certain new and useful Improvement in Side Bear ings for Railway-Cars, 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 for railway cars.

One object of the invention is to provide a novel form of side bearing for railway cars, which is of economical construction,

eflicient operation and so arranged that theanti-friction roller employed therein will antomatically return to normal central posi-- tion each time ,after it has performed its function.

The invention furthermore consists in the improvements in the parts and devices and in the novel combination of the parts and devicesherein shown, described or claimed.

'In the drawing, forming a. part of this specification, Figure l isan elevational view Showing .a truckbolster and body bolster. of a rallwaycar having my improved slde bearings attached thereto. Fig. 2 1s an enlarged sectional view taken substantially on the line 22 of Fig. l and illustrating the side bearing in normal position ofthe parts. Fig. 3 is a vertical sectional view taken substantially on the line 3 -3 of Fig. 2 and Fig. 4 is a View similar to Fig. 21and showing the position of the parts when the side hearing is performing its functlon.

In said drawing, 10 denotes the body bolvided with inner and outer depending side walls 14, each of which in turn isprovided with depending arms 15 at the corners thereof. On the upper inner side of the bracket 12, is provided a bearing plate 16, preferably of steel, which is secured to the bracket proper by means of rivets 17 or other suitable means. Extending through each pair of depending arms 15 is a more or less flexible strip 18 having the ends thereof upturned as indicated at 19, each strip 18 bemg downwardly inclined from each end to the center thereof and thereby forming inclined tracks with the lowest point at the center on which rides the extended ends 20 .of'a journal 21. Said journal 21 is preferably rotatably mounted in a pair of journal bearing members.2222 and secured to said jour'nal between the journal bearing members 22, and extending above the tops of the latter, is an anti-friction roller '23, which. as clearly shown in Fig. 4;, 'i s adapted to en-. gage and roll upon the wear or 'thrustplate 16. Each of the journal bearing members 22 is extended below the bottom ofthe antifriction roller 23 and is fiat lower surface 24. p

As shown in Fig. 2, in normal position of the parts, theroller 23 is out of engage ment with the weal-plate 16 and'ther'e is also a space between the lower surfaces of the members 22 and the wear or'thrust surface 25 formed on the upper side of the truck bolster 11., It will also be'noted that the roller are bo dilylnovable and are or may be brought to rest at various positions upon the surface 25 and the roller brought into play against the wear plate 16. 'ith this Patented A r. 11. 1916.

75. provided with a arrangement. the wear on the two wearingh surfaces is distributed over a greater area thereof. thus increasing the life of the hearing andthe roller can be brought into play to serve its function as an anti-friction element between the two bolsters at any relative radial position of the holsters.

I have herein shown anddescrihed what I now consider the preferred embodiment of my improvement, but the same is merely aside bearing for railway cars, a

r norr n1 separate from but adapted engage w th saic'i'surface', a journal for T d roller; and "bodily movable journal bearfor said journal, said journal bearings l "mg normally suspended from said join-- combinationhy'ith a member'provided with bearingsurface,'ofjroller supporting membera'a' roller mounted on said members, said roller -and members being bodily movable as an entity; and'theroller being adapted to engage said bearlngsurfaoe-when the s de bearing is bein actuated;

- 3. in a' 'de bearmg'for railway cars, in

combination; with "body and truck bolsters eachfhavinga bearing'surface; of an antifriction roller, ournal bearmg members by rich "Isaid roller is rotatably supported, d members and roller being interposed bemt of contact therewith the journal bearmg members being bodily movable and 3 apted tobe brought in engagement with one of the bearing surfaces at difierent points thereon a are a side bearing for railway cars, a roller, journal bearing members, a journal on'wliich said roller-is mounted and having its ends extended beyond said members, and inclined tracks on which said extended ends, are adapted. to ride, whereby said roller and journal bearing members are adapted to return to normal position under s the influence of gravity.

' 5. na side bearing ior railway cars, the

con" ition with r a body. bolster, of a bracketsecured thereto, a roller, supporting rovided With a bearing surface, a

.'.:.- in .a side bearing for-railway (are, the

said bearing surfaces and normally members arranged to be shifted bodily relatively to said bracket and by which said roller is rota-tably supported, and means and supporting members.

7 6. In a side bearing for railway cars the combination with a car body bolster of a bracket secured thereto, inclined tracks car ried by said brackets, a roller, journal bearing members, and a journal. for supporting said roller and having its ends extendingthrough' and beyond said bearing'lnembers and on saidinclined tracks.

'i'. In a side bearing for railway cars, a bracket adapted to besecured to a bolster said bracket having-a bearing surface, tracks secured to said bracket, and having oppositely inclined portions, aroll'er carried by a journal having the ends thereof adapted to rest upon said inclined tracks, and journal bearing members through which said jtnirnal extends, said roller, journal and i journal bearing members being bodily mov .able as a unit.

8. A side bearing for roller, and bearing members therefor-{stud bearlng members having faces on which they are adapted to rest and having the center of weight of the material forming the '50 upon saidbracket for retaining said roller sis cars comprising a same so arranged that said faces are always held downwardly under the influence of gravity. o i j V l 9. A side bearing for cars comprising a roller, a journal extending through said roller, and journal bearing memb'ersfin w-hichsaid journal is mounted, said members having flat surfaces on which they are adapted to rest, the center 'of eight of the material forming said member-slicing arranged below said journal to, thereby always maintain said faces, at the bottom under the influence of gravity.
