Application October 4, 1935, Serial No. 43,477
9 Claims.
The invention relates to articulated cars par
ticularly applicable to the economical transpor
tation of freight or goods in container lots and
more particularly to improvements in brake ap~
5 plying equipment therefor.
The principal objects of the‘invention are to
provide a simple but effective means operable
from one of the car sections for uniformly ‘ap
plying the brakes on both car sections and to
10 provide a brake-connecting means between the
respective sections which will permit wide rela
tive displacement of the car sections with the
minimum effect on the braking equipment.
The principal feature consists in the provision
15 of an articulated ?exible brake equipment oper
able from one of a pair of car sections and hav
ing an operative connection between the respec
tive sections which is guided in special relation
to the longitudinal vertical centre plane of the
20 car sections to e?‘ecti'vely brake the wheels of
both‘sections of the car under varying conditions
of load and position.
In the accompanying drawing Figure 1 is a
diagrammatic elevatio-nal view of an articulated
25 car to which the present invention is applicable.
Figure 2 is a plan view of the coupled ends
of the car sections, one section having the deck
(Cl. 188-34)
coupling such cars with a permanent ?exible
coupling as shown but not claimed herein to thus
provide a full length car having four, compara
tively uniformly distributed wheel supports

be achieved.
'
In the structure herein illustrated a car com
prises two sections A, B, each having a suitable
frame l carrying suitable journal guides in which
the axles of the wheels 3 are mounted equi~ 10
distant‘from each end. The frame 5 as. herein
shown is preferably a unitary casting having a
longitudinal box-like centre 4 with lateral arms
5 extending outwardly therefrom to support any
desired form of superstructure carrying a deck 15
6, which will be provided with suitable guides
and means for supporting the removable goods
containers 1.
’
One end of each of such car sections A, B, is
provided with any suitable form of draft rigging
and the adjacent ends of said sections are per
manently connected in an articulated manner
by a draft rod 9 which may be suitably spring
buffed.
It will be understood that a car constructed
in two sections connected together as described
will be adaptable to» carry individual loads and
removed showing the bare frame.
such loads will, because of the arrangement of
