COMPLETE SPECIFICATION.
Improvements in Railway Barriers, and Signals therefor.
We, PAUL RUPPERT, of Langenöls, Silesia, and ALBERT SILBERMANN of
74 Blumenstrasse, Berlin, Germany both Manufacturers, do hereby declare the
nature of our invention and in what manner the same is performed to be
particularly described and ascertained in and by the following statement :-
$6
The present invention relates to railway barriers and consists of the combination
therewith of signals such as a Danger signal" and a "Line clear" signal or any
other desired signals in such manner that when the barrier is closed, the "Danger'
or "Halt" signal will be visible from the road, whilst if the barrier is inadvertently
left open this signal will be visible to the engine driver, so that he may slow down
or stop before reaching the barrier. The invention is of great importance in
connection with barriers, particularly at night time, when the most accidents occur
on level crossings.
And in order to render the present Specification more easily intelligible reference
is had to the accompanying drawings in which similar letters denote similar parts
throughout the several views:-
Fig. 1 being a side elevation of the device in connection with a vertically
swinging barrier when the latter is down,
Fig. 2 a plan of Figure 1.
Fig.
3 a similar part elevation with the barrier up,
Fig. 4 a plan of a sliding barrier and
Fig. 5 a side elevation of a hinged barrier.
Referring to Figures 1 to 3 :-The barrier A is hinged to the standards a which
are provided with horizontally extending arms b, carrying the post c having at the
top the signal device, lamp, disc or the like. In order now to turn the Danger
signal towards the road and the "Line clear" signal towards the rail when the
barrier is down and the "Clear" signal to the road and Danger signal to the rail
when the barrier is up, it will be necessary to turn the post round a quarter of a
turn at each operation of the barrier, or round a quarter of a turn at each
operation of the barrier, or round and back a quarter of a turn at each two
operations of the barrier.
One way of accomplishing this is to fix a collar d having an arm f, rigidly to
the post cand connect to the end of said arm either by a loose pin and hole
or an universal joint, the free end of a lever / pivoted at its opposite end to
the barrier A at a point a suitable distance from the pivot of said barriers to
turn the lamp or signal post round and back successively at each closing and
opening of the barrier. As will be readily understood from the drawing, if the
barrier is moved from the position shown in Figure 1 to that shown in Fig. 3
the post will be turned round a quarter of a turn shifting the signals as
specified. In Fig. 4 a sliding barrier is shown the post c being provided with a
fork i into which a pink on the top of the barrier engages and turns the post
at each movement of the barrier a quarter of a turn in successively changing
directions. A second piu m is adapted to close against the outside of the
fork when the barrier is open and prevent an unauthorised tampering with the
sigual.
Fig. 5 shows the arrangement of a hinged barrier, in which case it is only
necessary to fix the post c ou the barrier over its hinge pivot when it will be
turned as required at each movement of the barrier.

page_text: We do not confine ourselves to any particular kind of mechanism for gearing
the signal post to the barrier, since the signal may be arranged at any point on or
near the barrier as desired.
Having now particularly described and ascertained the nature of our inven-
tion and in what manner the same is performed we declare that what we
claim is :-
66
1. A barrier for level crossings having means for showing a Danger" signal
and "Clear" signal simultaneously to the road and rail according to the position
of the barrier substantially as described.
2. A combination of a moveable barrier and a revolubly mounted signal post and
means for rotating said post a quarter of a turn at each movement of the barrier as
specified.
3. The combination of a moveable barrier and a revolubly mounted signal
post having an arm rigidly fixed thereon and means in connection with said
barrier for swinging said arm a quarter of a turn at each motion of the barrier as
specified.
