PROVISIONAL SPECIFICATION.
Improvements in and relating to the Delivery of Stopping Signals
to Moving Trains.
I, GUSTAV PUMPTOW, of Schkeuditz, in the Empire of Germany, Railway
Official, do hereby declare the nature of this invention to be as follows:-
This invention is especially intended to give a signal to the engine driver
during the movement of the engine, that the line is not clear or that the gates
of the level crossings are not closed. For this purpose there are arranged at a
distance of about 10-20 meters from each other, 3 gallows-like erections the
extreme ends of which reach the middle of the rails. The cross bar of the middle.
one of these erections is movable and is connected with the gates, barriers or
signal by means of a wire. Between these three erections is arranged a wire
which can be pressed downwards or upwards by the cross bar of the middle
erection. In the ordinary or resting position the wire is pressed down by the
cross bar of the middle erection so that a feeler or signal lever arranged on the
engine must slide along the wire and causes a bell signal to sound in immediate
proximity to the engine driver. The tension of the wire is necessary in order to
withstand the shock of the lever at the velocity of the train. This device is
provided at frequented level crossings and the like, and is connected with the gate
by means of a wire and will considerably augment the security of railway travelling
since persons or vehicles cannot be run over as the engine driver previously
receives a stopping signal when the barrier is not closed.

COMPLETE SPECIFICATION.
Improvements in and relating to the Delivery of Stopping Signals
to Moving Trains.
I, GUSTAV PUMPTOW of Schkeuditz, in the Empire of Germany, Railway
Official, 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:-
This invention is especially intended to give a signal to the engine driver
or other person during the movement of the engine, or moving train that the
line is not clear or that the gates of level crossings are not closed. For this

page_text: purpose there are arranged at a distance of about 10-20 metres from each other,
3 gallows like erections a b c, the extreme ends of which reach over the middle
of the rails. The cross bar d of the middle one of these erections (Figs. 1 and 2)
is movable and is connected with the gates, barriers or signal by means of a wire e.
Between these three erections is arranged a wire f which can be pressed down-
wards or upwards by the cross bar d of the middle erection b. In the ordinary
or resting position (Fig. 1 and 2) the wire is pressed down by the cross bar d of
the middle erection b, so that a feeler or signal lever g arranged on the engine
must slide along the wire and causes a bell signal to sound in immediate proximity
to the engine driver. The tension of the wire is necessary in order to withstand
the shock of the lever caused by the velocity of the train. This device is pro-
vided at frequented level crossings and the like and is connected with the gate
by means of a wire and will considerably augment the security of railway tra-
velling, since persons or vehicles cannot be run over as the engine driver previously
receives a stopping signal, when the barrier is not closed.
In the annexed drawing:-
Fig. 1 shows the device in side view where the wire is pressed down, so that
the feeler touches the latter and thus causes the bell signal to sound.
Fig. 2 shows an end view of Fig. 1. Fig. 3 shows the feeler or signal lever in
side view on a larger scale, whilst Fig. 4 shows the same in front or end view.
The feeler or signal lever shown in Figs. 3 & 4 carries on the top of the pivoted
fork a roller which is pressed against the tensioned wire by means of the
counter weight k. The fork h carries on its axle also a lever m as shown in
Fig. 3 on the end of which lever m is fixed a chain n, which running between 2
rollers o, is attached at the other end to a trip rod q, which as soon as the
feeler is pressed down by the tension of the wire, is raised by the lever m and
chain and deflects & trips the hammer of the bell causing the hammer to
strike the bell.
Having now particularly described and ascertained the nature of this inven-
tion and in what manner the same is to be performed I declare that what I
claim is:
Improvements in and relating to the delivery of stopping signals to moving
trains in which a feeler or signal lever arranged on the engine or moving train
slides against a wire stretched aove the rails and deflected into the path of said
lever when a signal is to be given, such lever being then deflected and causing
an audible signal to be given to the engine driver or other person on the engine
or train.
