> 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

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.
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.
