WEsT- United States, resid- To all whom Be it known Lann, 4a citizen of the ing in the city of St. Missouri,y useful which the `following is a full, clear, and exact description, such as will enable others skilled in the art vto which it appertains to make and udse: the saine, reference being ha tol the accompanying drawings, forming part ,oi this specification.

My invention relates to new and useful improvements in car trucks and particularly to roller supports for car-bodies, whereby when the car body rounds a curve at comparatively high speed the centrifu al force developed# is .uthze t0 elevate 15.3 Outer transverse movement of the car body, the Side of the @at body t0 a hghe' lane thm' upper bearing plates 11 which are fit-ted to the lnne' S1133, thus absol'bng t e Centlf' the bolster partake of the movementof the ugal force by making it raise ay car bo and when rounding a Acurve at coi-naratively low speed the lateral thrust r uced by the super-elevated outer trac raillis utilized to elevate the inner side of the .car body, thus tending to level said car body and preventing all tendency of said body to overturn. 9

In the drawings: Figure 1 is a transverse sectional view through my improved car truck. Fig. 2 is an end elevational view of the parts shown in Fi 1. Fig. 3 is a view of some of the parts slgiown in Fig. 1, showing the changed position thereof. Fig. l is a sectional view on line 4-4, Fig. 2. Fig. 5 is a horizontal sectionalview on line 5`5, Fig. 1.

1 designates the dy: .bolstel. The bearing rollers 13 at the side of the car above one track rail ride upwardly and outwardly on the inclined planes 1() of the lower bearing plate 9 and on the outwardly. inclined planes 12 of the upper bearing plate/11. The end of the bolster which is supported by these rollers is therefore elevated. Simultaneously with the action just described the roller bearings 13 between the bearing plate 9 and 12 at the oppositev end of the bolster or that end located above the other track rail roll upon the approximately horizontal lportions of the tracks 10a and 12, and consequently, this end of the bolster is appreciable degree, or only sufficiently elevated to make the lrollers self-centering, By thus' elevating one end of the bolstera'the 'sam'eis tilted and as a result the car body cants inwardly with respect to the arc ot the track curve and as a result of this movement the center of is not moved outwardly as far or to the same point as if both sides of said car body were raised a like amount and at the same time shifted laterally. Such action tends to maintain the equilibrium of the cnr and avoids undue thrust of the wheels on the outer rails of the curve. The wheels of the car are thus. caused to remain on both rails of the curve notwithstanding the tendency of centrifugal force to throw the flanges ot the wheels against the outer rail of the curve.
