Improvements in Railway Couplings.
We, JOHANN DILITZ and MICHAEL KRETSCHMANN, both of Vienna, 11. Scher-
zergasse No. 1, in the Empire of Austria, Manufacturers, do hereby declare the
nature of this invention to be as follows:-
The present invention relates to improvements in railway couplings and has for
its purpose to arrange the coupling device of railway carriages in such manner
that the coupling and the uncoupling the screwing together of the coupled carriages
as well as the hanging on or attaching of the reserve coupling device can take place
from alongside the carriage or from the roof or the seat of the railway guard or
of the brake man thereon if such be provided easily and rapidly without it being
necessary for the man who couples the carriages to go between the carriages or use
any particular instrument.
For this purpose the coupling provided with a screw and hanging on the drawbar
of the carriage is raised from alongside or from above by means of a bearer or porter
and can be hung over the hook of the coupling device of the next carriage, the bearer
or porter and the coupling which is provided with a screw being connected with one
another by toothed wheels in such a manner that by means of an arbor arranged on
the front of the carriage and provided alongside of the same with wheels which are
operated by hand a rotation can be transmitted to the screw of the coupling device
by means of bevel gears for the purpose of screwing the couplings together or
unscrewing the same.
A. peculiar advantage of these improvements consists therein that the coupling
device which has been raised by means of the bearer or porter may be retained in
its raised position by means of a slider, so that also without the intermedium of any
person the coupling device of an approaching carriage will fall over the hook of the
next rarriage the coupling device working thus automatically.
In the accompanying drawings this new method of coupling is represented as
follows
Fig. 1 is a part elevation, part section on line of Fig. 3 of this coupling device
arranged on coupled railway carriages.
Fig. 2 is a view of the coupling which can be operated from above.
Fig. 3 is a plan view of the same.
Fig. 4 is a plan view of the bearer or porter.
Fig. 5 is a plan view of the coupling device.
Fig. 6 is a view of the raised bearer or porter and of the coupling device.
Fig. 7 is the bolt or slider.
In all figures the same characters indicate the same parts.
A is the coupling provided with a screw fixed to the draw bar a³ and able to
rotate. It consists in a screw spindle a provided with right handed and left handed
screw threads and on which the toothed wheel a' is rigidly fixed. On the threads
of the screw are arranged the screw nuts a² a² with the bow A' and the turning

bearer of the bow A' and of the flap A2 to prevent these latter from untimely
turning and to retain the same in the direction of the axle if the coupling device is
lifted up.
The bearer or porter C serves as couch for the arbor c¹ on one end of which is
fixed the bevelled wheel c² and on the other end the toothed wheel C. The arbor
is put in rotation by bevelled wheels c d this rotation being transmitted to the
toothed wheel al

page_text: The bearer or porter C is fixed on the hollow arbors gg which are capable of
being turned and which lie in the bearings g' g' arranged on the end frames G of
the carriage. Each axle gg is provided at its outer end with a lever H H. If
the lever Hor His oscillated on either side of the carriage and in the required
direction the bearer or porter C will oscillate equally.
In the hollow arbors g lies the shaft c on which are fixed on the inner side of
the conical wheel d serving to move the shaft e¹ and on the outer side and on both
sides of the carriage the wheels K K which are operated by hand.
If one of the latter wheels are turned the rotation is transmitted by means of the
conical wheels c²d the shaft c' the toothed wheel C' and the toothed wheel a¹ to the
Screw spindle a so that the coupling device is screwed together or unscrewed.
M is a vertical shaft which can be operated from the seat of the brakeman and
this shaft transmits the rotation to the screw spindle a by means of the conical
wheels m and d the shaft c¹ the toothed wheel C¹ and the toothed wheel a' thereby
operating the coupling device which is provided with a screw thread.
On the hollow arborg is fixed a segment of a cog wheel a into which gears a
conical wheel n' on the vertical shaft N so that the bearer or porter C can be
oscillated from the seat of the brakeman in the same manner as by the levers H
and H
D is a hook fixed on the bearer or porter and capable of being turned and serving
to form a reserve coupling device (Fig. 1) that is to say if two carriages are already
coupled the lever H of one of the carriages and the lever H of the other one or
the vertical shaft, N is turned so that the hook D catches into the link A² of the
opposite coupling device. At one side of the carriage is arranged the bolt L (Fig. 7)
which serves to retain the raised support with the raised coupling device in their
position, for if the lever H is turned the bearer or porter and consequently also the
coupling device are lifted up. By pushing forward the bolt L the lever H' which
has been bent down and equally the raised bearer or porter and the raised coupling
device are maintained in their position.
The use of this coupling device is as follows. The lever H or H or the shaft N
is turned in a required manner whereby the bearer or porter is sufficiently raised.
Now the carriage is pushed forward and the link falls into the hook of the other
carriage. Then the hand wheel K or K or the shaft M is turned, so that as
described heretofore the coupled carriages are rigidly drawn to one another by
means of the wheelwork e dorm d the shaft the toothed wheel C³, the toothed
wheel a' and the screw spindle a.
The coupling can take place also automatically if the coupling device as before has
been raised in the required manner by means of the lever H or H or the shaft N
and if the bolt has been pushed forward. The link falls in this case automatically
into the hook of the next carriage.

COMPLETE SPECIFICATION.
Improvements in Railway Couplings.
We, JOHANN DILITZ and MICHAEL KRETSCHMANN, both of 30, Hauptstrasse,
Vienna, in the Empire of Austria, Manufacturers, 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 improvements in railway couplings and has for
its purpose to arrange the coupling device of railway carriages in such manner that
the coupling and the uncoupling, the screwing together of the coupled carriages as
well as the hanging on or attaching of the reserve coupling device can take place

page_text: D is a hook fixed on the bearer capable of being turned and serving to form a
reserve coupling device (Fig. 1), that is to say if two carriages are already coupled
the lever H of one of the carriages and the lever H of the other one or the vertical
shaft N is turned so that the hook D catches into the link A² of the opposite
coupling device.
At the end of the carriage is arranged the bolt L (Fig. 6) which serves to retain
the raised bearer with the raised coupling device in their position. For if
the lever H or H or the shaft N is turned the bearer and consequently also the
coupling device are lifted up. By pushing forward the bolt L by means of the
handles the bent lever H and consequently the raised bearer and the raised
coupling device are maintained in their position by the nose on the bolt being
shifted over the nose of the arborg and therefore preventing the return of the
arbor gas long as the bolt is not withdrawn.
The use of this coupling device is as follows.
The lever H or Hor the shaft N is turned in the required manner whereby the
bearer and the coupling device are sufficiently raised. Now the carriage is pushed
forward, and the link falls into the hook of the carriage. Then the hand wheel K
or Kor the shaft M is turned, so that as described heretofore the coupled carriages
are drawn together by means of the wheel work 2d or md the shaft e the toothed
wheel C¹ the toothed wheel a' and the screw spindle
u.
The coupling can also take place automatically if the coupling device as before
has been raised in the required manner by means of the lever H or H or the
shaft N and if the bolt has been pushed forward. The link falls in this case
automatically into the hook of the next carriage.
Having now particularly described and ascertained the nature of our said inven-
tion, and in what manner the same is to be performed, we declare that what we
claim is
