Improvements in and relating to Antomatio Couplings for
Railway Carriages.
We, ISAAC ROBINBOHN, Merchant and HERMANN RODINSOHN, Engineer both of
23 Wilmersdorferstrasse, Charlottenburg, in the Empire of Germany do hereby
declare the nature of this invention and in what manner the same is to bo
performed to be particularly described and ascertained in and by the following
statement:-
This invention relates to a double coupling for railway carriages to be coupled
automatically by the buffers, the connection of the conpling being offected by the
encountering of the buffers of two carriages and capable of being disengaged by the
simple operation of a levor which may occur when carriages are to be slipped during
motion or when stationary.
In the annexed drawing the improved coupling is shown in side view.
The draw hook a carrios a bolt b which forms the axle for the main coupling
linked and the safety hook e. The link cd and the safety hook e are to be
approached to one another up to a certain angle, which is determined by the position
of a pin upon the safety hook e, so that by means of this pin e' the book either
moves the linked upwards with its further upward movement or it lets the link c d
fall downwards with its downward movement.

The buffer rod p carries a projecting arm o which at the encountering of two buffers
moves backwards with the buffor rod and pushes against the nose n of a rotary bolt r.
Upon this bolt is seated the sleeve 4, which for the guiding of the projection
provided with a hollow, in order to allow the sleeve to turn on the bolt within
certain limits.
is
With the sleeve is solidly connected an arm k, which bent like a hook at its end
engages with this hook over the projection of a second sleeve i and prevents the
latter from turning to the left. This sleeve i turning round the bolt his connected by
the army and the connecting rod with the safety hook e.
When the conpling is in the position shown by the full lines in the annexed drawing
and the buffers of two carriages meet together, the projection or arm o connected
solidly with the buffer rod p is pushed against the nose n of the sleeve / and turns
the sleeve to the right. The hoop like arm is lifted, and frees the pin i, whereby
the safety hook, which as already mentioned is in connection with the sleeve i loses
its support and falls downwards. The main coupling link c d resting on it falls also
downwards and thus enters the draw hook of the other carringe.
When the coupling is to be disconnected, the handle X on the sleeve i is pressed
downwards so that the safety hook e and the coupling link cd are lifted and both
are again kept in their raised position by the book of the arm k.
The coupling of two carriages can however also be effected by hand and not
automatically. Here the hook and the nose i' are disengaged by pressing down the
lever y provided on the bolt r.
The sleeve carries besides the nose a second nose i', against which also the hook &
cau bo laid, when the coupling will obtain a position as shown in the annexed
drawing in dotted lines, that is to say, when the main coupling link is laid down, in
order to receive the safety hook of the coupling of the other carriage.
When a carriage is to remain uncoupled although the buffers are pushed back, the
main coupling link o d and the safety hook e must remain in the lifted position ;

page_text: therefore disengaging of nose i¹ and hook must not take place. In order to obtain
this, the bolt is provided with a nose r¹, which can turn to the left in the hollow
of the sleeve 1. When the nose is brought from the vertical into the horizontal
position by means of the handle y, also the nose n will lie under the arm o, so that
the latter at the movement of the buffers cannot push against this nose, but slides
over it and so does not cause Buy turning of the sloove and therefore no disengaging
of the parts i' and k.
Having now particularly described and ascertained the nature of this inven-
tion and in what manner the same is to be performed we declare that what we
⚫claim is :-
(1.) An improved double coupling for railway carriages to be engaged automatically
by the buffers and consisting of the rotary sleeve which is provided with an arm k
engaging with its hooked end over a nose provided on the sleeve i and which
thus prevents the sleeve i from turning to the left in consequence of the weight of
the safety hook and the main coupling link c d until the parts & and are disengaged
by the arm o which arranged on the buffer rod p pushes against the projection n of the
sleeve on the back movement of the buffer rod p.
C
(2.) In the double coupling as described in Claim 1 a device for preventing automatio
operation by means of which the bolt r can be turned to the left, the nose moving
in a corrosponding hollow, whereby the nose n is brought out of the path of the
-arm a, without the hook being disengaged.
