or bearing lug 3| ai; its `base portion, which is adapted to seat in the pocket |2|. The lug 3| has its outer lower corner rounded off, as indicated at 32, to properly cooperate with therounded inner bearing surface 22 at the base of the transverse section of the flange i4.

The portions of the Walls 23-23 which form the side Walls of the roller containing chamber are outwardly enlarged, as indicated at |32-l32, to provide bearing supports for the trunnions of the roller C, as hereinafter will appear. The en-i larged portions |32|32 of the walls are provided with bearing seats 33-33 which are open at the top. The seats 33-33 have concave bote tom walls on which the trunnions of the roller C are adapted to rest. 'I'he outer walls of the seats 33-33, which are designated by 34-,34, are relatively thin so that the upper end portionsthereof may be bent or bowed inwardly, as indicated at 35-35, to overhang the trunnions of the roller and prevent accidental removal of the roller.

The roller C is in the form of a solid cylinder and has trunnions 36-36 which rest in the bearing seats 33-33 within which they are rotatable. As shown most clearly in Figures l, 3, and 4, the roller C protrudes above the housing to-properly contact the underneath surface of the body bolster HJ. i Y

The spring D is housed in the chamber 28 of the housing B and rests on the base plate l2'. The upper end of the spring bears on the underneath face of the top wall 21 of the housing, thus normally holding the housing in the raised position shown in Figures 1 and 3. The top wall 21 of the housing is preferably provided with an inwardly protruding hollow boss 31 which `ex tends Vinto the coil of the spring D.

The housing B andthe base member VA are held assembledby'a retainer bolt 38 having its head 39 anchored tothe base plate |2 of the base member A. The shankof the bolt38 extends through aligned openings in the base plate |2 and the bottom wall of the hollow boss 31, and

4 of remote from its pivot and forcing said member' the bolt is anchored at its upper end to said boss' by the nut 40 thereof, which is accommodated in the opening of the boss.

As shown most' clearly in Figure 3, the bottom side of the housing B is convexly rounded transversely to permit transverserocking adjustment. of the housing on the base `plate I2. As further shown in Figure 3, the lug 3| of thehousingB fits the seat |2|rather,loosely to permit this rocking movement. The bottom side of the housing is inclined upwardly with respect to the top side thereof from Ithe end which is provided with the lug to the other end thereof, thus 1eav, Y ing a certain amount Vof clearance between the base plate l2 and the lower side of the housing at the spring chamber end of the latter to, allow upward and downward rocking of the housing on its lug 3| as a pivot. The expansive action of the spring D constantly holds the roller C against the bearing surface of the body bolster.

As will be evident the eiective capacity of the springis greatly multiplied due to the lever action of the housing B, thespring being at the outer end of the long arm of the lever which extends from the pivot lug 3| Vto the spring chamber, and the roller C being 'at the end of the short arm which extends fromV the pivot lug 3| to the point of support of the roller I I have herein shown and described what I now consider the preferred manner of carrying out my invention, but the same is merely illustrative and I contemplate'all changes and modifica'- tions that come within the scope ofthe claims appended hereto.

I claim:

l. In a side bearing for a railway car having body and truck bolsters, the combination with a supporting member pivoted at one end on one of said bolsters, said pivoted end being held against movement toward said last named bolster; of a roller rotatably supported on said mem ber between the ends of the latter; and spring means engaging said member at the end theretoward the other bolster.

betweenthe pivot thereof and the point of appli-- cation of spring pressure.

3. In a side bearing for a railway car having port on its pivoted end, the application of theA spring pressure to said support being more `re'` mote from the pivot thereof than the roller.

4. In a side bearing for a railway car having body and truck bolsters, the combination with a base member secured to one of said bolsters; of a housing having rocking engagement at one end on said base member; a spring interposed between said housing and base member at the other end of the housing to yieldingly support said last named end of the housing; and an anti-friction roller rotatably supported n said' housing` between the ends thereof and projecting therefrom to engage the other bolster, the ends of said housingbeing pressed `respectively against said base member and springby engagement of the roller with said last named bolster.

5. Ina side bearing for a railway car having-1 body and truck bolsters, the combination with a.

base member secured to one of said bolsters; of a.

housing pivoted at one end on said base member,`

said pivoted end being held against movement toward said last named bolster; an anti-friction roller` supported in said base memberbetween. the ends thereof and projectingtherefrom; and

-a spring at the other end of said housing inter-t` posed between the latter and the base member to` swing the housing on its pivot inr a direction. away from said base member. i

6. In a side bearingfor railway cars,- the c0111-,- bination with a base member; of a housing pivoted at one end only on said base membervfor swinging movement toward and away from said base member, said pivoted end being'conned against movement toward said base member;` a spring interposed between said housing and base member toswing the housing on its pivot; and an anti-friction roller mounted in said housing intermediatethe pivot thereof and the point of' 4application of the-spring pressure/said roller projecting from the' housing,` the axis of rotation of said roller being xed with respect to the housing. f

7. In a side bearing for railway cars, the combination with a base member; of a housing p ivoted at one end on said base member for rocking movement longitudinally, said housing and base member having opposed bearing surfaces, one of which is crowned transversely to permit lateral rocking of the housing on said base member; an anti-friction roller mounted in the housing and projecting therefrom; and spring means interposed between the base member and housing at a point spaced from said pivoted end of the housing to swing the latter on its pivoted end away from the base member.

8. In a side bearing for railway cars,. the combination with a base member having a flat top bearing surface; of a housing pivoted at one end on said base, said housing having a transversely rounded convex bottom face havingtransverse rocking engagement with the fiat top surface of the base member; a spring interposed between the base member and the housing a1; a point remote from the pivot of the latter, said spring yieldingly supporting the housing on said base member; and an anti-friction roller rotatably supported in the housing at a point less remote from the pivot thereof than the spring.

9.
