PROVISIONAL SPECIFICATION.
Improvements in Apparatus for Communicating Signals on Railway
Trains.
I, PATRICK DALEY of Sabarmati near Ahmedabad in Guzerat, India, Engine
Driver Rajputana and Malwa Railway do hereby declare the nature of this invention
to be as follows:-
My invention relates to apparatus whereby the guard on a railway train can signal
by day or night to the driver, and also whereby passengers can signal to the
guard or driver. For this purpose, I mount in the guard's van pivotted arms
carrying coloured screens or glasses which by the movement of the arms can be
made to project through slits at both sides of the van simultaneously, and to
remain so projected and visible to the driver until the guard again draws them
in. The coloured screens are thus made to serve as a danger signal by day, and
the coloured glasses as a danger signal by night these glasses being arranged to
come in front of the side lights of the van.
The signal arms are moved simultaneously by one action of a handle or they
may be acted on by a weight or spring so as to move immediately to the danger
position on release of a catch, the guard thus having his hands free to work
the brake.
I provide also the passenger carriages with pairs of coloured screens which on
the passenger pulling a cord or moving a bandle are thrust out simultaneously at
both sides of the carriage from under the roof. In order that the guard or
passenger may call the driver's attention to the signals displayed, I provide a
communication throughout the train such as I have set forth in my Provisional
Specification No. 7915 of 1887 consisting of rods swung so as to be capable of
longitudinal movement under the carriages, and coupled by chains from carriage to
carriage and to the bell or gong on the locomotive. I connect the signal arms
above described to these communicating rods, so that one movement serves to strike
the bell or gong and at the same time to display the signal.

I PATRICK DALEY of Sabarmati near Ahmedabad in Guzerat India, Engine
Driver Rajputana and Malwa Railway, 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:-
My invention relates to apparatus whereby the guard on a railway train can
signal by day or night to the driver, and also whereby passengers can signal to
the guard or driver. For this purpose, I mount in the guard's van pivotted arms
carrying coloured screens or glasses which by the movement of the arms can be
made to project through slits at both sides of the van simultaneously, and to remain
so projected and visible to the driver until the guard again draws them in. The
coloured screens are thus made to serve as a danger signal by day, and the
coloured glasses as a danger signal by night, these glasses being arranged to come
in front of the side lights of the van. The signal arms are moved simultaneously
by one action of a handle, or they may be acted on by a weight or spring so as to
move immediately to the danger position on release of a catch, the guard thus
having his hand free to work the brake.
I provide also the passenger carriages with pairs of coloured screens which, on the
passenger pulling a cord or moving a handle, are thrust out simultaneously at both
sides of the carriage from under its roof.
The carriage communicating signals for passengers' use only are fitted on the
top of a carriage, and work in connection with the communication, both being
attached to each other by chains; the chain is fitted on to the end of each lever
which stand at angles on the front and back of each two compartments; the chains
are carried to the centre and are passed over two pullies and led along the top of the
carriage from both ends to the centre where they enter over two small rollers into
each compartment below and are attached to the communication chain and handle near
the roof where the communication chain is passed from each compartment over two
other small pullies and runs down to the centre portion and is attached to each
other near the bottom frame of the carriage, here there are two small pullies fitted on
the bottom frame of the carriage leaving space sufficient in the centre of both pullies
for the communication chains to pass freely, the communication chains being attached
near the bottom are led out under each pulley, one leg is led to the right leading
suspender rod while the other leg is led to the left trailing suspender rod,
where both are attached to each rod in their respective positions and are ready
for using.

page_text: The signal rods are fitted to the inner end of each lever, and rest on brackets
which they slide on when required for danger, each lever stands on one pivot and
works freely with the pull from below; one pull gives the signals and alarm; the
signals are stationary after the first pull, they remain at danger until enquiry
is made, then the guard in charge will remove them by a chain which is attached at
the outer ends of each lever and over a small pulley and hangs on the right back
corner of one compartment and on the left front corner of the other; but the passenger
in need of assistance may ring the bell.on the engine as often as he likes till the train
comes to a stand, without interfering with the signals or any other compartment after
they are once given. The above carriage has two compartments, each compartment
having two sliding signals fitted on the centre of the inner roof to slide out one at
each side of the compartment, and which can be seen from the engine and brake at
either side of the train when the alarm is given.
In order that the guard or passenger may call the driver's attention to the signals
displayed, I provide a communication throughout the train, such as I have set forth in
my Specification No. 7945 of 1887, consisting of rods swung so as to be capable of
longitudinal movement under the carriages, and coupled by chains from carriage to
carriage and to the bell or gong on the locomotive. I connect the signal arms above
described to these communicating rods, so that one movement serves to strike the bell
or gong and at the same time to display the signal.
Fig. 1 of the accompanying drawings represents an engine and tender attached to
a carriage and brake van. The side of the brake van is supposed to be removed and
shews a lever M. which on a catch being unfastened shifts a cog wheel on the shaft N.
from a pinion on a shaft working the day signals to that working the night signals
and vice versa. The wheel J on the same shaft N worked by a cord, may also be used
to put the signal to danger when worked from outside either from a passenger
carriage or from the engine, by the wire cord J C joined to the communication
rods A A.
The guard can by means of the handles N¹ move the signals K.
The passenger carriage shews the wire cord passing between the partitions thereof,
which cord may be used either to expose the danger signals on the roof as shown in
dotted lines at Figs. 2 and 4 or to work the danger signals of the brake or
for both.
Figs. 2 of the drawings shews an under view of the brake carriage tender and
engine, and the signalling connections.
Fig. 3 shews the day signals at Danger. Fig. 5 shew them withdrawn Fig. 6
represents the night signals placed before the lamps to signal danger..

page_text: 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 :-
1. The Brake Van danger signals and apparatus for working them; substantially
as described.
2. The Passenger Carriage danger signals, and apparatus therfor substantially
as described.
3. The combination of the several danger signals in a train and of the apparatus
therefor substantially as described.
