Railway car truck. ~ , Bearing rollers I1 aremounted on' said cones > The invention relates to trucks for railway , l3 and the cups l8 or outer bearing members 5 5 cars whose axles are mounted in antifriction bearings and it has for its principal object to relieve the bearings of such an axle of torsional strains due to‘ individual wheel or axle move ments relative to other parts of the truck. The are mounted in said housing ll, whose outer end is closed by a cap 19 that is secured to the housing by screws 20 and that has an inward ly extending sleeve portion 2! that abuts. against the outermost bearingv cup I8. The in- 10 loinvention consists principally in mounting the nermost end of the bearing housing II is closed bearing housing of‘ such an axle or frame ‘in ‘by a ring‘22 ‘that is secured to the housing by vsuch a way as to permit such housing to have a pivotal movement about an axis transverse to the axle and also about a vertical axis, such 15 double pivoting of the bearing housing permit ting self-alining movement of the bearings and thus relieving them of .torsional strains. The _ screws 23_ and has a sleeve portion 24 extending inwardly into the bearing housing, abutting against the innermost bearing cup l8 to hold 15 it in position. The drawing shows only one ‘end portion of one axle, it being'understood that the other end portion of the other axle will be of similar construction and that the. truck side truck and in the parts and combinations and ar-" frame member may be of any well-known type. 20 invention further consists in the railway car 0 rangements of parts hereinafter described and claimed. In the accompanying drawing, v ' ' - _ Fig. 1 isa partial vertical sectional view of " a railway car axle and the adjacent portion of 25 a car truck embodying my invention, Fig. 2 is a transverse vertical sectional view on the line 2-2 in Fig. 1, looking in the direc tion of the arrows ;v and - , Fig. 3 is a sectional view on theline 3--3 in 30 Fig. 2, looking in the direction of the‘ arrows. In the drawing is shown a truck side frame I of common construction provided with an end portion that has spaced perforated bosses 2 on its under side to receive a‘ pin 3 that is disposed 35 transversely of the axle 4. Mounted’on vsaid While the bearing arrangement just described is a preferred arrangement, it is understood that the invention is not limited to any specific hear ing arrangement, but is concerned with the piv otal mounting of the-bearing housing. 2‘ ' The above described mounting of the bearing housing permits swinging movement of the bear ings and housing about an axis transverse to the axle and also about a vertical axis. Thus self alining movement of the bearings and housing '30 is permitted while maintaining tightness of ?t of the parts underallconditions. Obviously, numer- ' ' ous' changes might be made, particularly in the truck side frame construction and in the bearing arrangement, without departing from the inven- 35 tion. and I do not wish to be limited to the pre construction shown. portion 6 of cylindrical con?guration oscillatable cise .What I claim is: in a concave‘seat ‘I provided on the under side 1.
