Car-coupling.
I, FERDINAND GRÜN, Manufacturer of 48 Herzogstrasse Cologne in the
Province of Rhineland and Kingdom of Prussia do hereby declare the nature of
this invention to be as follows:-
In the accompanying drawing in Fig. 1 the heads of two railway carriages
supplied with coupling apparatus are represented. In Fig. 2 the coupling which
has taken place may be seen in an upper-view, while Fig. 3 shows a side-view of
the fall-hooks with eyes which are opposite each other, as well as their positions
when they do not touch each other.
The coupling apparatus consists essentially of two arms b, in which the axle c
rotates, attached to the cross-head a. On this axle there is attached the fall-hook d
with the eye d 2. The latter are made of one piece and are at an angle of 70° to
each other. In order to cause this coupling-apparatus to act automatically when
two carriages meet, it is necessary that in the carriage which is in motion, the fall-
hook be brought into a horizontal position by the levers e and retained in this position
by inserting the pawl fin the toothed wheel g. As soon as the nose h has reached
the eye d 2 and slides over its upper margin the hook is raised, thereby causing
the whole apparatus to be turned backwards, the pawl coming out and the fall-
hook falling with the nose into the eye. In this position the fall-hook which is
situated under the coupled eye, lies with its shaft near the part i (vide Fig. 3).
and thereby offers a support to the eye as well as to the fall-hook lying on it.
Carriages that are standing close to each other are coupled by the fall-hook being
turned by means of the lever e as far as the eye of the other carriage and the eye
being laid so far back that it is out of the reach of the fall-hook. Then the eye
is lowered first and on it the hook (vide Fig. 3).
In the case of a carriage being pushed against another, the coupling takes
already place before the buffer-plates touch each other. Carriages are uncoupled
likewise by means of the lever e, the nose h of the fall-hook being lifted out of the
eye and held firm by the insertion of the pawl in the toothed wheel. The
carriage may now be moved away. But if the uncoupling is to be done without
removal of the carriage, then the fall-book is laid so far back that it allows the
eye to go past then the fall-hook is lowered first and there upon the eye. The
rising-plane o (Fig. 3) in case of two carriages meeting with a considerable shock,
raises the fall-hook and thus preserves it as well as the front of the carriage
opposite to it from damage. The springs k attached to the draw-rods are intented
in order to weaken the pull when the carriages are started.

I, FERDINAND GRÜN, Merchant of 48 Herzog Street in Cologne in the
Province of Rhineland and Kingdom of Prussia 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 :-
In the drawing filed with the Provisional Specification in Fig. 1 the heads of
two railway carriages supplied with coupling apparatus are represented. In
Fig. 2 the coupling which has taken place may be seen in an upper view while
Fig. 3 shows a side-view of the fall-hooks with eyes which are opposite each other,
all well as their positions when they to not touch each other.
The coupling apparatus consists essentially of two arms b, in which the axle c
rotates, attached to the cross-head a. On this axle there is attached the fall-
hook di with the eye d
The latter are made of one piece and are at an angle of 70° to each other. In
order to cause this coupling-apparatus to act automatically when two carriages
meet, it is necessary that in the carriage which is in motion, the fall-hook be
brought into a horizontal position by the lever e and retained in this position by
inserting the pawl fin the tooth'ed wheel g.
As soon as the nose h has reached the eye d' and slides over its upper margin
the hook is raised, thereby causing the whole apparatus to be turned backwards,
the pawl coming out and the fall-hook falling with the nose into the eye. In this
position the fall-hook which is situated under the coupled eye, lies with its shaft
near the parti (vide Fig. 3) and thereby offers 'a support to the eye as well as to
the fall-hook lying on it.
Carriages that are standing close to each other are coupled by the fall-book
being turned by means of the lever e as far as the eye of the other carriage and
the eye being laid so far back that it is out of the reach of the fall-hook.
Then the eye is lowered first and on it the hook (vide Fig. 3). In the case of a
carriage being pushed against another, the coupling already takes place 'before
the buffer-plates touch each other. Carriages are uncoupled likewise by means of
the lever e, the nose h of the fall-hook being lifted out of the eye and held' firm
by the insertion of the pawl in the toothed wheel.
The carriage may now be moved 'away. But if the uncoupling is to be done
without removal of the carriage, then the fall-hook is laid so far back that it
allows the eye to go past then the fall-hook is lowered first and there upon the
eye. The rising plane (Fig. 3) in case of two carriages meeting with a considerable
shock, raises the fall-hook and thus preserves it as well as the front of the
carriage opposite to it from damage. The springs attached to the draw-rods
are intended in order to weaken the pull when the carriages are started.
Having now particularly described and ascertained the nature of my said inven-
tion and in what manner the same is to be performed, I declare that what I
claim is :-
An automatic coupling for railway vehicles, thereby distinguished that hook (d¹)
and eye (d) consist of one piece, are arranged at an acute angle to each other and
are moveably mounted on an axle (c) so that on the axle turning, hook and eye
may be interchangeable.
