PROVISIONAL SPECIFICATION.
Improvements in or relating to Bogie Trucks for Rolling Stock.
I, JOHN JULIUS ADLER, of Ajmere, Rajputana, East India, Assistant to the
Carriage and Wagon Superintendent of the Rajputana-Malwa State Railway, do
hereby declare the nature of this invention to be as follows:-
This invention has for object to prevent or lessen the peculiar and disagreeable
vibration usually experienced when travelling in railway carriages supported upon
bogie trucks and which is mainly due to shocks imparted to the bogie frame from
the wheels whilst running over points and other uneven portions of the rails.
For this purpose I interpose between each pair of the suspension rods that are
connected to the adjacent ends of the metal bearing springs at each side of the
bogie frame and the underside of such frame, a beam which is suspended from the
pair of suspension rods and bears against the bogie frame through the intervention
of springs that may advantageously be of india-rubber. The other ends of the
metal bearing springs are or may be connected to the bogie frame in the usual
As will be
manner through springs, which may also be of the kind mentioned.
obvious my invention can be applied to tramway vehicles and to bogie trucks having
two, four, or more pairs of running wheels.

COMPLETE SPECIFICATION.
Improvements in or relating to Bogle Trucks for Rolling Stock.
I, JOHN JULIUS ADLER, of Ajmere, Rajputana, East India, Assistant to the
Carriage and Wagon Superintendent of the Rajputana-Malwa State Railway, do
hereby declare the nature of this invention and in what manner the same is to be
performed to be particularly described and ascertained in and by the following
statement:-
This invention has for object to prevent or lessen the peculiar and disagreeable
vibration usually experienced when travelling in railway carriages supported upon
bogie trucks and which is mainly due to shocks imparted to the bogie frame from
the wheels whilst running over points and other uneven portions of the rails.
For this purpose I interpose between each pair of the suspension rods that are
connected to the adjacent ends of the laminated bearing springs at each side of the
bogie frame and the underside of such frame, a beam which is suspended from the
pair of suspension rods and bears against the bogie frame through the intervention
of auxiliary springs that may advantageously be of india rubber. The other ends
of the laminated bearing springs are or may be connected to the bogie frame in the
usual manner through auxiliary springs, which may also be of the kind mentioned.
As will be obvious my invention can be applied to tramway vehicles, and to. bogie
trucks having two, or more pairs of running wheels.
In the accompanying drawings
Fig. 1 shows partly in side elevation and partly in longitudinal section;
Fig. 2 partly in end elevation and partly in transverse section (to a larger
scale); and

page_text: In Figs. 1 and 2 a part of the underframe of a vehicle that is partly supported
by the bogie truck is shown in section.
1, 1 are beams arranged longitudinally, at the sides of the bogie frame 2 and each
suspended from the adjacent ends 3 of the laminated bearing springs 3 by the
suspension rods 4. The connection between each of these rods and the corresponding
beam may advantageously be effected through an india rubber auxiliary bearing
spring.5 which is interposed between the underside of the beam and a plate 6 which
is carried by a nut 7 on the rod, and by means of which the connection can be
suitably tightened. 8,8 are india rubber springs each interposed between one end
of each beam 1 and a bracket 2* carried by the bogie frame to which bracket the
end of the beam is secured by a bolt 9 and nut 9. 10 10 are links, one only of
which is shown in Fig. 1 by which the other end, of each of the laminated bearing
springs 3 is connected through an india rubber auxiliary: bearing spring 11 and
plate 12 to a bracket 2b secured to the bogie frame 2.
The bolster may be hung from or connected to the bogie frame in any suitable or
convenient manner..
In the construction shown in Figs. 1, 2, and 3, the bolster 13, is carried by
longitudinal swing beams 14 each of which is hung from the bogie frame by
suspension links 15 each of which is connected with the bogie frame and swing
beam through upper and lower india rubber springs 16 and 17.
By the construction described all shocks are completely absorbed and prevented
from being transmitted to the body of the vehicle resting on the bolster.
Fig. 4 is a side elevation, and
Fig. 5 a half plan showing a modified construction of bogie according to this
invention.
Fig. 6 is a cross section on the lines A A of Fig. 5.
In this arrangement the beams 1 and the metal bearing springs 3 from the
adjacent ends of which the said beams are suspended, are arranged inside the
longitudinal frame plates 2 of the bogie truck, the ends of each beam being secured
through the india rubber bearing springs 8 to a longitudinally arranged plate 2*
and brackets 2 fixed to the inner side of the corresponding frame plate. The
bolster 13 is in this example fixed to the bogie frame.
Having now particularly described and ascertained the nature of this inven-
tion and in what manner the same is to be performed I declare that what I
claim is:-
1. A bogie in which from laminated bearing springs at the sides thereof there is
suspended a beam that bears through auxiliary springs against the underside of the
bogie frame so as to partly support the same.
2. A bogie constructed with beams 1, applied and arranged at each side thereof
as described and shown.
3. My improved bogies constructed as herein before described with reference
respectively to and shown in Figs. 1, 2 and 3, and in Figs. 4, 5 and 6 of the
drawings annexed.
