Apparatus for Communicating on Railway Trains.
I, PATRICK DALEY, of Sabarmati near Ahmedabad in Guzerat, India, Engineer
Rajputana State 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 means of communicating on railway trains between the
engine driver and the guard or between passengers and the engine driver. I prefer to
make the communication in duplicate the one part, exclusively for the guard and
engine driver, and the other for passengers' use; but a single communication may
serve for both uses.
Under each vehicle of the train I hang by suspending links a light metal bar or
rod which is of the same length as the vehicle and terminates at each end in a
short piece of chain with coupling hook, so that, when a train is made up, all the
bars are coupled together. The line of the one bar or of each bar should be as
near as possible to the longitudinal centre line, so as not to be materially affected
in length when the train runs round a curve. The bar or bars of the tender may be
connected to a lever which acts on a gong or whistle so as to give the driver an
audible signal when either bar is pulled backwards. From the bar under each
carriage a wire or other cord or chain is led over guide pullies to some convenient
part of the carriage with a knob or handle accessible to passengers, and in like
manner a knob or handle is provided in the guard's van. I prefer to enclose the
passengers' knob or handle behind a glass front which must be broken to give access
to it, and also to provide a flag or other signal which is thrust out when a passenger
signals, and is kept out by a catch so as to shew in which carriage the signal is
given.
Fig. 1 of the the accompanying drawings is a side view and Fig. 2 a plan looking
from below of a tender and several carriages with means of communicating according
to this invention. A A are the rods or bars suspended free to swing longitudinally by
hangers E from brackets D attached to the under framing. These rods are coupled
from carriage to carriage by the pieces of chain B provided with suitable hooks, and,
if necessary, with additional links to allow for wider spaces between the carriages.
For each carriage a separate chain C is led over guide pullies F to a suitable pull or
handle G accessible to passengers, preferably only after breaking a glass covering it.
The rod A of the tender works a lever H for sounding the bell or gong of which there
may also be one on each guard's van.
As stated above, there may be only a single line of communication by the rods A
and coupling chains B; generally however it is preferable to have two lines as
indicated at Fig. 2, one for the service of passengers and one for the use of the
guards and drivers.

page_text: Having now particularly described and ascertained the nature of this invention
and in what manner the same is to be performed, I declare that what I claim is :-
For communicating on railway trains, a set of bars, suspended free to swing longi-
tudinally under the carriages, and coupled by chains from carriage to carriage, in
combination with suitable pulls or handles accessible to the passengers and officials on
the train, and with a bell or gong on the tender or guard's van, arranged and operating
substantially as described.
