Improvements in and connected with Railway Brake Apparatus.
I, WILHELM JACKEN, of 21 Steinweg, Wetzlar, in the Empire of Germany
Foreman, 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 :-
The present invention relates to a brake apparatus for railway vehicles which
comes into action as soon as the propelling power is slackened down, and which
automatically acts upon all the wheels in a train.
The invention is represented in the accompanying drawings, in which Figure 1
is a side view partly in section, Figure 2 is an end view and Figure 3 is a plan of
part of the unler carriage of a railway carriage or wagon provided with my
improved brake apparatus working in connection with two buffers of the ordinary
type, but I would have it understood that my improved brake apparatus can be
adapted to other systems of buffers, such, for instance, as central buffers.
C
The buffer rods a a are carried back through the buffer beam 6 and are con-
nected to the ends of a cross beam c which is strongly but loosely connected to a
slide d. This slide d, in its rearward motion, acts upon the upper end of a lever,
whose lower end is connected to a rod a¹, which is connected to the upper end of
the weighted lever a³, whose lower end is connected to the brake blocks y by the
rod, cross rods a, lever and rods x. Thus, in the rearward motion of the
slide d, the latter, by its connections, causes the brake blocks y to press against
the wheels. The rod a¹ is continued along beneath the carriage or wagon and is
connected to all the brake blocks of a carriage or wagon as above described, so
that they shall all be operated simultaneously. The buffer rods a a are so con-
structed as to play loosely to and fro during the ordinary running of the carriage
or wagon without exerting any influence on the brake rods, but as soon as the
brake is applied to the locomotive a strong back pressure is produced on the buffer
discs of all the vehicles in the train and consequently the brakes are applied to all
the wheels.
As before mentioned the cross beam c is strongly but loosely connected with the
slide d; the object in view is to enable the brake to be disconnected during the
shunting and backing of the train.
This can be done by means of a pin e passing through both the slide d and the
cross beam c, which pin e is held by a lever f, the outer end of which latter has to
be lifted in order to disengage the pin e from the cross beam c and thereby sever
the connection between the slide d and such cross beam c. All the levers f of a
train can be manipulated by a cord g extending all along the train and guided by
guide pulleys, as shown, so as to disengage all the brakes simultaneously.
Having now particularly described and ascertained the nature of my said
invention and in what manner the same is to be performed I declare that what
I claim is :-
1. A brake apparatus for railway carriages or wagons comprising buffer rods
elongated at their rear ends and connected to a slide, which, when forced backwards
by the action of the buffer rods, acts upon the brake rods and causes the brake
blocks to press against the wheels, substantially as herein shown and described.
2. In a brake apparatus for railway carriages or wagons such as that referred
to in Claim 1, a disconnecting connection between the buffer rods and the slide, and
a lever operated by hand or by a cord to effect the disconnection, substantially as
herein shown and described, and for the purpose stated.

page_text: 3. In brake apparatus for railway carriages or wagons, the peculiar arrange-
ment and combination of parts whereby the buffers, when forced backwards, are
caused to apply the brakes, and whereby the connection between the buffers and
brake apparatus is capable of disconnection, substantially as herein shown and
described.
