four-wheel freight car trucks.
same looking toward the right as Viewed in Fig
It is an object of this invention to provide a ure l.
clasp brake arrangement having a brake beam
Inasmuch as both sides of the brake arrange- \
interchangeable with the standard truss type

this brake arrangement is acceptable in inter
change service.
10y Another object isoto provide a brake arrange
ment for cars having restricted clearances such
as between the slope sheets and trucks of hopper
cars.
-' 'Still another object is to provide a brake ar
v15 rangement wherein the weight of the parts is
kept at a minimum, and the rigging is inexpen
sive to make and maintain and fulfills all re
quirements of manufacture and service.
>Yet another object is to provide a brake ar
20 Y rangement wherein the beam is effectively bal
anced to prevent dragging of the top of the shoes
on the wheel.
A different object is to provide a brake arrange

is shown and described.
In the car truck illustrated, which is of the 10
four-wheel type, the side frame I [I is substantial
ly of truss construction including the tension
member I2, compression member I4 connected
adjacent the ends thereof and provided with
spaced pedestals I6 for reception of journal 15
means I8 of the spaced wheel and axle assem
blies 20. Spaced columns 22 integrally connect
the tension and compression members and provide the substantially centrally disposed window
24, said window being adapted to receive the ends 20
of the transversely disposed load carrying mem
ber, which, in the construction illustrated, corn
prises the bolster 2B. Said bolster is provided
with> the centrally disposed center bearing 28,
suitable side bearings 30, and end spring seats 25
A still different object is to provide a brake ar
32 whereby the bolster may be supported on the
rangement preserving maximum clearances, the
spring seat 34 provided in the window through
same being so arranged that no part of the brake
is above the brake beam at the one end, such as

A yet diiierent object is to provide a truck and
brake construction wherein the weight and num
ber of parts carried by certain of the brake
beams, such as the outer ones, is kept at a mini
35 -mum as the effect of vibration is very severe on
the hanging and balancing means, particularly
of the outside brake beams.
With these and variousrother objects in View,
the invention may consist of certain novel fea
40 tures of construction and operation as will be
more fully described and particularly pointed
out in the Specification, drawings and claims ap
pended hereto.
