55 Claim.
This invention relates to railway car trucks,
and more particularly to brake mechanism par
ticularly adapted for the new type of light high
speed cars.
5
An object of the invention is to provide a truck
and brake arrangement in which there is proper
?exibility between various portions of the truck
to permit of easy and uncramped operation
thereof and of the brakes, and at the. same time
10 maintain sufficient rigidity to meet safe oper
ating requirements.
Another object is to provide brake mechanism
for such trucks which will have the necessary
clearance for e?ective ‘operation within a rela
15 tively small space.
'
-
Still another object-is to provide a truck and
brake combination particularly for the light high
speed railway cars adapted to meet the .various

Referring first of ‘all more particularly to the
truck construction illustrated, the truck consists
essentially of the truck frame" having spaced
side frames 22 integrally connected by means of 10
the spaced transoms 24 forming a bolster open
ing for the reception of the usual load carrying
member or bolster 28. The truck illustrated is
of the inboard type, the truck being supported by
means of the spaced wheel and axle assemblies 28, 15
the axles being generally indicated in side eleva
tion as at 30.

l The side frames are provided with the pedestal
jaws 32 normally spaced from the journal means
(not shown) having bearing cooperation with 20
‘the wheel and axle assemblies. _'lhe side frames
are provided with inner and outer wing castings
