page_text: I, GEORG AREND, of 70c. Schönhauser-Allee, Berlin, in the Empire of Germany,
Manufacturer, do hereby declare the nature of this invention to be as follows:-
This invention has reference to an improved automatic car-coupling consisting
of a socket suitably secured to the buffer-plank of the car and serving to receive
the coupling-hook made of two parts. Said hook is first secured in the fore-part
of the socket by means of an internally threaded sleeve or nut having external
teeth and screwed on said hook, and between said sleeve and the fore, end of the
socket is a suitable spring for the purpose of taking up the jerks produced on the
coupling hook. Said sleeve or nut and therefore the hook may be rotated by
actuating a lever extending downwards through a suitable shot in said socket.
The rear part of the coupling-hook is formed of a round bar having a larger
diameter than the fore-part of said hook, and connected with said fore-part by
means of a suitable extension of the hook engaging a guide-groove in said, rear
part. The latter is secured within the aforesaid socket by means of a sleeve
fitted over said round bar and held within the socket in any suitable way, and
preferably provided with internal screw-threads engaged by a guide-pin extending
from said round bar. Between the latter sleeve and a nut screwed on the round
bar, is a coil-spring of suitable strength. The outer surface of the socket is
provided with teeth meshing with a gear-wheel journaled in the car-frame, and
carrying an actuating lever whereby the whole device may be rotated so that
the hook of one car might be placed parallel with that of the next, for the
purpose of separating the cars.

I, GEORG. AREND, of 70c, Schonhäuser-Allee, Berlin, in the Empire of Germany,
O Manufacturer, 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 subject of the present invention is a coupling for railway wagons which is
particularly characterized by the fact that the coupling hook, which is made in

page_text: two parts or pieces, is capable of lending itself to all the shocks or jars imparted
to the carriage, without any fear of its being broken. The arrangement permits,
moreover, the wagons to run separately the ones from the other, and furthermore
the said hooks are secured by a very simple arrangement.
'
In the annexed drawing the subject of the invention is illustrated; in section
in Fig. 1, and in front view in Fig. 2. Fig. 3, is a view in longitudinal section
showing another or modified form of construction thereof.
As will be seen from the drawing, the arrangement consists substantially of
the socket B which is either inserted or screwed into an aperture formed in the
sill or plate of the buffer, which socket serves to receive the look. This hook
is fixed in the first instance by means of a collar or coupling C in the form of
a toothed wheel secured in the outer end of the socket B and into which is screwed
the hook D:

j
Between the collar C and the front end of the socket B is interposed a spring E,
which latter serves to deaden or take up the strength of any displacement of the
collar when a shock or jerk is imparted to the hook.
A haud lever F passing through a slot or aperture in the socket B operates a
rotation of the nut and of the hook attached to it, in order to bring together the
hooks by screwing up or unscrewing until they touch and engage together com-
pletely. As, has been already stated; the hook is made in two parts or pieces,
and its rear extremity consists of a tail picce G, which is of a larger diameter, and
which is connected with the front extremity of the hook D by means of a guiding
groove which receives a feather or key H on the said hook D. This rear-piece or
portion G is secured in the socket B by a sleeve or collar K slid upon it and fixed
in any suitable manner in the socket B; the said sleeve, or cellar K is provided
on its interior or exterior surface with a screw thread. When this screw-thread
is formed on the interior surface, as is the case in the form or modification illus-
trated in Fig. 1, a suitable guiding pin or stud is so arranged upon the piece or
part Gas to permit this latter piece or part to slide along the said screw thread.
In the second form or modification the screw thread is cut or formed upon the
exterior surface of the sleeve or collar K and serves also to fix the sleeve or collar
in the socket B. Between the sleeve or collar K and and a nut L, fixed upon
the end of the tail piece G, is placed a spring i. In the form or modification
illustrated in Fig. 3, the tail piece is placed directly in the socket B, so that
in that case the sleeve or collar under the influence of the shocks, which it is
subjected to, and under that of the spring E, is capable of moving in a longitudinal
direction, in the free space thus formed, and then also the two parts or portions
of the hook are free to slide the one on the other, by means of the guiding
groove H. The entire arrangement, with the hook which is introduced into it
may be rotated by a rotary movement imparted by the lever to the socket B,
a portion of which is arranged to form a toothed wheel, and by the medium of
the toothed wheel transmission gearing M in such a manner that the hooks D
of the carriage will be directed in a parallel direction the one towards the other
and that the carriages may run separately.
The putting in place of the hooks is effected by first introducing the hook into
the perforation R of the socket B, the nut C being next screwed on having first
interposed the spring E, and by then introducing the tail piece G of the other
side and afterwards fixing it in place by means of the sleeve or collar K, in the
form of construction illustrated in Fig. 1.
The hooks can then be so regulated as to completely interlock or hook together
through the medium of the lever F.
When a shock or jar is imparted to the hooks, these latter can partially compen-
sate or allow for it horizontally by the fixing, through the spring and groove, of
the parts, and partially by means of the spring I located behind the sleeve or
collar K whilst an equilibrium of pressure in a vertical direction can be com
pensated for by the sliding of the guide pin or stud in the screw threads' on the

page_text: interior of the sleeve or collar K, partially in another form of construction, by
the rotation of the sleeve or collar K with the book contained by it, or else of
the hook itself and of its attachment G in the socket B.
By reason of the hooks being formed in two parts or pieces, the security of the
coupling and the guarantee of immunity from breakage are furthermore greatly
increased, for in the case of the occurrence of a shock or jar only one part of the
look will be affected and a shock or jar of an extraordinary degree of violence
would be required in order to bring both parts or pieces of the hook under its
influence.
Lastly in order that the carriages for railways or tramways may be capable of
separating with ease when the hooks are in a horizontal position, the hooks, as 18
shown in Fig. 2, are placed in such a manner that, when they are horizontal, their
lower side or upper side respectively may fall to the middle of the centre ligne
of the sockets, or better slightly higher. In Fig. 2 two of the above described
hooks D and D2 are arranged on each carriage.
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 coupling for railway and tramway carriages, and for vehicles of the same
description, characterized by the fact that the coupling hook D secured in a
rotating socket B by an adjustable nut C, is connected by a groove and by a
spring or by a similar guiding arrangement with a tail piece G fixed either
directly or through the medium of a sleeve or collar in the rear portion or part
of the socket in such a manner that the two parts or portions of the hook are
capable of sliding in a horizontal direction, whilst through the rotation of the
rear part or portion of the said hook or of the sleeve or collar K which serves
the purpose of fixing it in the interior of the socket, or else by the displacement
of the hook itself by means of a guiding pin working in a screw thread cut or
formed in the sleeve or collar, a displacement in a vertical direction can be
effected.
2. In a coupling for tramways and railways such as that claimed in the First
Claim, an arrangement for reducing the pull or work of a coupling hook charac-
terized by a front part or portion forming the coupling hook properly so called,
and which is connected by a groove and by a spring or by guiding hooks with the
tail piece G mounted directly in the socket, or fixed to it by the sleeve or collar K
and turning with this latter, or in the socket or the said sleeve or collar in such
a manner that the two parts or portions D) and G may be pulled or acted upon
by shocks or jars independently the one of the other.
3. A form of execution or construction of the coupling for the carriages of
railways, of tramways, such as that claimed in the First and Second Claims,
characterized by a sleeve or collar K surrounding the tail piece G connected to
the front part or portion by a groove and by a spring or by a guiding pin, and,
which on the occurrence of a shock or jar, is capable of turning with the coupling
hook by means of a screw thread which is formed on its external surface.
