34 Claims. (01. 188-56)
This invention pertains to car trucks, and more
particularly to a unit cylinder clasp brake ar
rangement for high speed articulated trailer
trucks.
It is an object of this invention to provide a
' four wheel truck for use with high speed articu
lated trains wherein a pair of cylinders is used
to operate clasp brakes provided on'said truck.
Another object of the invention is to provide a
brake arrangement for a low center of gravity
truck wherein unit cylinder brake operating
means is utilized.
Yet another object is to provide a brake ar
rangement adapted for use on trains of the high
15 speed type wherein positive and effective braking
truck and brake arrangement illustrated in Fig
ure 1;
Figure 3' is an enlarged end elevation of the
truck and brake arrangement, the same being
taken at the right end of said truck as viewed in
Figures 1 and 2.
The‘ truck illustrated consists essentially of
the truck side frame or side rails I0, the side
frames on each side of the truck being spaced
apart and integrally connected by means of the 10
spaced transoms 12 which are adapted to carry
the usual bolster in the conventional manner.‘
The truck is of the inboard type and is provided
at the‘ ends of said side frames with inner and -
outer wing castings l4 and 16 secured as at I8 15,

A further object is to provide a four wheel in
board truck having low sills and integral con
rubber washers or rubber “doughnuts” provided
between the wing castings and side frames to
necting transoms, the transoms supporting be

axle assembly being operated by unit cylinder
means provided on the truck between the spaced

A different object is to provide an equilizer for
each wheel and axle assembly of a truck, the
equalizer being supported on the truck and op
By the provision of wing castings and the rubber 25
cushion, a resilient cushion is provided between
the wheel and axle assemblies and side frame,
permitting relative movement therebetween, such
as angling when the truck is negotiating curves
erated intermediate its ends by a cylinder car
and that movement which is necessary for the 30
ried by the truck, the equalizer for each wheel
and axle assembly being operatively connected
to clasp brakes for the wheels.
A still different object is to provide a brake
system for a truck, carried by said truck, the
truck being supported through resiliently mount
cushions to absorb road shocks.
.
Where clasp brakes are contemplated, as in
the present truck, the brakes and operating
means may be carried directly by the side frame,
and to this end the transoms l2 are provided 35

Another di?erent object is to provide brakes
for a high speed typeof inboard truck which
ful?ll all conditions of manufacture and service,
and are inexpensive to make and maintain.
With these and various other objects in View,
the invention may consist of certain novel fea
45 tures of construction and operation, as will be
more fully described and particularly pointed out
in the speci?cation, drawings and claims append
ed hereto.
