PROVISIONAL SPECIFICATION.
Improvements in and relating to Communicating Apparatus for
Railway Passengers.
I, ERNEST HENRY DICKINSON, of Westbourne Villas, Selby, in the County of
Yorkshire, Gentleman, do hereby declare the nature of this invention to be as
follows:-
This invention relates to an improved apparatus whereby the passengers may
communicate by signals with the guard or driver of a railway train.
The invention consists essentially in providing a spring or other automatic shoot-
ing bolt fitted within a vertical case upon the outer side or sides of the carriages
between the two windows of adjacent compartments the said bolt as it falls
operating an alarm bell.
This case is formed with a vertical slot and a horizontal slot a pin or cross-bar
on the bolt engaging with the latter slot to hold the bolt in its upward position.
Above the said bolt is a box containing three guide pullies over which passes a
cord one end of which passes through the box and is connected to a cord running
along the top of the carriage and the other end to the pin on the bolt or the said
pullies may be dispensed with and the cord at the top connected by a rod with
the bolt.
These cords may be operated by means of levers two to each compartment
working between two plates and a slit in the side panels.
These levers act upon the pin of the bolts to disengage it from its slot so as to
permit the said bolts to fall thereby drawing down the cords and actuating a bell
or alarm in the guards van and on the engine.
The doors of the carriages may also be locked when an alarm is given by
means of horizontally sliding bolts operated by the motion of the vertical bolts or
instead of bolts a small tab or lever may be caused to fall and engage with sockets
on the side of the carriage.
The apparatus may be fitted on each side of the carriage and be so arranged
that one side shall signal to the guard whilst the other side signals to the
driver.

Improvements in and relating to Communicating Apparatus for
Railway Passengers.
I, ERNEST HENRY DICKINSON, of Westbourne Villas, Selby, in the County of
Yorkshire, Gentleman, do hereby declare the nature of this invention and in what
[Price 8d.1

page_text: which bears against or is connected to a pin or rod sliding in a socket 63 and kept
in contact with the arm b' of the bolt b so that as the arm is pushed off the
catch dit moves the arm outwards causing it to turn on its pivot into the
horizontal position shewn in dotted lines.
For the purpose of locking the doors of the compartment in which the signals
have been given I fit by the side of each door a sliding spring bolt m Fig. 5 which
is operated by means of a pivoted lever or catch n engaging with the pin m² on the
bolt so as to bring the said pin in line with the slot o of the tube or slide of
the bolt.
The lever or catch n is connected by a chain or cord n¹ to a lug g³ on the sup-
port g of the pullies g so that as the latter are pulled down by the spring c the
lever or catch turns the pin m' into engagement with the slot and permits the
bolt to shoot forward into the socket p on the door 7 of the carriage thus securely
locking the same.
The axis of the lever or catch passes through the compartment to the other side
of the carriage in order to act at the same time on the bolt of the opposite
door, the mechanism being so arranged as to lock the said bolt in the reverse
direction to the other one.
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) The improved apparatus or mechanism for communicating between the
passengers guard and driver of a railway train comprising a spring bolt fitted
within a casing outside the carriage and held in its normal position by means
of a catch from which it is disengaged by a push-pin or lever inside the carriage
for effecting a pull upon a cord coiled around a series of pullies attached to the
said bolt and also around a series of guide pullies fixed to the side of the carriage
the said cord leading to the guards van and engine where it operates a gong for
signalling to the guard and engine driver substantially as described.
(2) In apparatus for signalling between the passengers guard and driver of a
railway train the combination with the outer panels of the carriage of the bolt b,
formed with arm b', spring c, swivel joint c¹, bracket c², catch or plate d, case c,
provided with a door e¹, and box e, guide pullies f and g, bracket f', support g¹
swivelled at g², cord h, push-pin i, lever k, indicating arm pivoted at 1, exten
sion 2, pin or rod 62, and socket, all arranged and operating substantially as
described and shewn in the drawings and for the purposes specified.
(3) In signalling apparatus as above claimed the combination therewith of the
spring bolt m, lever or catch n, pin m¹, slot o, chain or cord n¹, lug g³, socket ?,
and door y substantially as described and for the purposes specified.
