RAILWAY-CAR `lEtGlIiLEl.*SIDE BEARING. p
To all whom t may concern l Be it known that I, S'iAoY B. Hasnilrinn, a citizen of the United States, residing at Chicago, in the county of Cooli and State of lllinois, have invented a certain new and useful Improvement in Railway-Car Roller Side Bearings, of'w'hich the following is a full, clear, concise, and exact description,
reference being had tothe accompanying drawings, forming a part of this specification. Y
This invention relates to improvement-s in railway car roller side bearings.
An object ofthe invention is to provide a roller side bearing for railway cars consist ying of few parts, easily manufactured and readilyl assembled, and spring means for automatically returning the roller toits central normal position after each `actuation thereof, which spring means performs its function through ythe intermediary` of a member in which the roller has its bearings.
The invention furthermore consists in' the improvements in the parts and devices and in the novel combinations of the parts. and devices, as herein. shown, described or claimed. i
1n the drawing forming a part of this specification, Figure 1 isanend elevationv of portions of a car body bolster and a'truck' shown, said bearing is attached to the truck bolster, but as will be apparent to those skilled in the art, it may be attached to the body bolster, if desired.
' The improved roller bearing A comprises a base casting 12 riveted or otherwise suitably secured to the truck bolster, said casting 12 being provided on its upper face with insertedroller tread plates 13 made of steel or other suitable material adapted to resist Wear. Extending longitudinally on the Speeiication of Letters IP-atent.
Patented May 2, 1916.,
sides of said casting 12 are ribs or tongues 14 whichfcoperate with correspondingly shaped grooves 15 formed on the inner sides and groove arrangement above described,
,the casting `17 is permitted to slide back and forth on the casting 12 and is prevented `from vertical or transverse removal there from. The casting 12 is centrally slotted as indicated at 18 and in thisfslot reciprocate depending arms or a-butments 19-19 cast integrally on the ends 'ofthe feasting 17.
is a longitudinally arranged coil `spring 21 shoulders .or stops 23 formed` within the re- -cess 2O.v Each of the spring caps 22 is prolvided with an inwardly extending boss 24 on which an end of the spring is carried, there- `of depending flanges 16 cast integral`-with a lsecond casting 17 By means of the tongue .The casting`12 is also hollowed out centrally i `as indicated at `20and mounted therewitliin bysuplporting the latter. At thebottom of the recess 20and on eachside thereof, the
casting 12 is' provided with supporting guideways 25 for thespringcaps or followers 22 to reciprocate upon. As clearly appears from Fig.'V 2, the depeiidingarms 19-'19 of the casting 17 are normally in engagement with the spring followeis 22 so that the casting is thereby centered with respect to the base casting 12. i The casting 17 is provided with a substantially rectangular centrally located opening 26 in which is mounted an anti-friction roller 27, the latter being supported on a shaft 28 extending through the roller and having its ends mounted in suitable recesses in the side walls of the casting 17. To minimize the wear between the roller 27 and supporting shaft 28, a bushing 29 may be employed. rlhe ends of the shaft 28 are flattened as indicated at 30 and the surrounding metal of the casting 17 hammered or peened thereagainst to prevent the shaft from rotating and also from coming out.
The diameter of the roller 27 is such that it normally lifts the casting 17 slightly from the top of the casting 12. ln operation, pressure being applied to the roller 27 from the thrust plate of the body bolster, the roller will roll upon the tread or wear plate 13 and the casting 17 which the roller is mounted will move thel direction of rota'- tion of the roller, thus compressing thel spring 21.
As clearly shown in the drawing, the plates13-13 are beveled at their ends asV indicated at 31 and the length ofysaid plates is such that the anti-friction rollers will al'- ways bear thereupon within ordinary limits latter" turning about and being supported ontheir own shafts and without translation bodily.y Upon release of the pressure, the
springs wilI return therollers' to their nor- 'mal position', the inclined en'ds 31 facilitating the lifting of thel roller and the' casting ir which it is carried.
In theV construction shown in Figa 4, a base casting2112 isprovided, the' same having a tread plateinsert 113 on which rolls the rel-1er 127.- The latteris mounted on a shaft 128 supported and carried by a reciprocatingcastin 117 havinT a; ton -ue and 2D ZD .groove in slidable engagement, 114:V and 115,
the casting 112 at the ends of the chambers 120; The operation of this arrangement is substantially the same as that above described for the construction illustrated in Figs. 1 to 3.
I claim 1. In a roller side bearing for railway cars, the combination with a base casting, of a second casting slidably mounted thereon', means automatically operable for positioning said slidable casting centrally of the base casting, said slidable casting having a centrally disposed opening in the top thereof, an anti-friction roller within said opene ing, and a journal on which said roller is carried, said journal having its ends mounted in the side walls of said slidable casting.
2. In a roller bearing for railway cars, the combination with a base casting having a roller tread surface, of a second casting slidably mounted on the base casting, spring means for centering` the slidable casting on the base casting, an anti-friction roller rotatably mounted in the slidable castingand bearing and rolling upon saidy tread surface under normal conditions, said slidable casting being movable suiiiciently to permit the anti-friction roller to pass ofi' of said tread surface and allow the roller to rotate about its own axis under excessive actuation of the bearing.
In witness that I claim the foregoing I have hereunto subscribed my name this 24th day of March, 1915.
