Improvements connected with the Working of Railway Trains.
We, PHILIP CONWAY DAVIES, of 174, Westminster Road, Liverpool, in the
County of Lancaster, Passenger Agent, and WILLIAM GRAHAME HOPE, of
Magazines, New Brighton, in the County of Chester, Gentleman, and WALTER
JOHNSTONE, of 24, Saxony Road, Liverpool, in the County of Lancaster, Joiner,
do hereby declare the nature of this invention to be as follows:-
According to our invention we provide on or in connection with the rail or rails
of railway lines, devices or means worked by the usual semaphore or other
mechanical signal that will, as the engine passes over, come in contact with and
work devices or means on the engine in connection with the steam supply, and so
cause the closing, or partial closing, of the steam supply to the engine, and also
cause the putting on of the brake at the same time or shortly after, and cause a
warning signal to be given by ringing or striking a bell or gong, or sounding
the whistle.
As an example of the carrying out of our invention we provide on or by the rail
or rails of the railway, and at a point near the distance signal, a device such as an
inclined bar or cam so connected by rods, levers, wires, or equivalent connections,
with the signal or working parts of the signal, that when the signal is placed to
indicate danger the device will be raised or otherwise moved so that it will come in
contact with a device on the engine, which device in connection with, and will
work (shut off) the steam supply to the engine. The device on the engine may
consist of a rod, shoe, or wheel or like device, carried under, or at the side of the
engine and connected by suitable gear, such as rods, levers, or the like, to the
throttle valve or stop valve or reversing lever of the engine in such a way that as
the device on the engine comes in contact with the device on the rail, the device
on the engine is moved and causes the shutting off of the steam to the engine.
Further along the railway line and near to the home signal, we place a second and
similar device on the.rails worked by the home signal. This device works a device
on the engine in connection with the brake gear, so that, as the engine passes over
this point, if the home signal is at danger the brake is automatically applied
to the train. This device may also be applied to work the brake froin the
guard's van.
In connection with the device on the engine to shut off the steam, and to apply
the brake, we provide on the engine a gong or other sounding device which is
worked (sounded) as the steam is shut off or the brake is applied, said sounding
device being worked by the steam shutting off gear or by the brake applying gear,
as the case may be, and in the case of the brake being applied from the guard's van
a sounding device may be placed there also.

COMPLETE SPECIFICATION.
Improvements connected with the Working of Railway Trains.
We, PHILIP CONWAY DAVIES, of 174, Westminster Road, Liverpool, in the
County of Lancaster, Passenger Agent, and WILLIAM GRAHAME HOPE, of
Magazines, New Brighton, in the County of Chester, Gentleman, 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 :-
According to our invention we provide on or in connection with the rail or rails
of railway lines, a device or means worked by the usual semaphore or other
mechanical signal that will, as the engine passes over, come in contact with and
work devices or means on the engine in connection with the steam supply, and so
cause the closing, or partial closing, of the steam supply to the engine, and also
cause the putting on of the brake at the same time or shortly after, and cause a
warning signal to be given by ringing or striking a bell or gong, or sounding the
whistle.
As an example of the carrying out of our invention we provide on or by the rail
or rails of the railway, and at a point near the distance signal, a device such as an
inclined bar or cam so connected by rods, levers, wires, or equivalent connections,
with the signal or working parts of the signal, that when the signal is placed to
indicate danger the device will be raised or otherwise moved so that it will come in
contact with a device, on the engine, as the engine passes it which device is in
connection with, and will work (shut off) the steam supply to the engine. The
device on the engine may consist of a rod, shoe, or wheel or like device, carried
under, or at the side of the engine and connected by suitable gear, such as rods,
levers, or the like, to the throttle valve or stop valve or reversing lever of the
engine in such a way that as the device on the engine comes in contact with the
device on the rail, the device on the engine is moved and causes the shutting off
of the steam to the engine. Further along the railway line and near to the home
signal, we place a second and similar device on the rails worked by the home signal..
This device works a device on the engine in connection with the brake gear, so
that, as the engine passes over this point, if the home signal is at danger, the brake
is automatically applied to the train. This device may also be applied to work the
brake from the guard's van.
In connection with the device on the engine to shut off the steam, and to apply
the brake, we provide on the engine à gong or other sounding device which is
worked (sounded) as the steam is shut off or the brake is applied, said sounding
device being worked by the steam shutting off gear or by the brake applying 'gear,
as the case may be, and in the case of the brake being applied from the guard's van,
a sounding device may be placed there also, the operating device being in this case
on the guard's van.

Having thus generally described the object, nature, and effects of the invention,
we will now proceed to describe it with reference to the sheets of accompanying
drawings, in the various figures of which the same parts are designated by the same
letters and they correspond with those used in the following explanation.
DESCRIPTION OF THE DRAWINGS.

the devices on the railway line are worked direct from the signal box.
Figure 6 is an elevation of the arrangement shewn at Figure 5.
Figure 7 is a side elevation of a locomotive engine shewing a modified arrange-
ment of the devices for actuating the steam supply and the brake.
Figure 8 is a plan of the actuating wheels.
Figure 9 is an end view of the engine cab illustrated at Figure 7, shewing the
steam supply and brake devices.
With reference to the drawings (Figures 1 and 2), a designates a portion of the
rail of a railway line in the vicinity of the distance sigual, and a' the portion of the
rail in the vicinity of the home signal. designates the "distance". signal, and
e the "home" signal. These signals are of the ordinary semaphore type. d is the
wire by which the "distance" signal is worked, and e is the wire by which the
"home" signal is worked. h designates the device in front of the distance and
home signals. This device may consist of a rail h in two parts connected by a
hinge at k placed outside of and parallel with the rail a, the ends of the rail
working on slides h¹ one end being connected by a wire to a weighted lever /³, and
the other end being connected by a wire h³ to the wire d of the "distance" signal.
The rail is provided with rocking levers attached to the sleepers, or otherwisé
suitably supported so that as the weighted lever pulls the rail.h forward; the
rail will rise above the rail a in an inclined position, having its raised part nearest
the "distance" signal, as shewn at Figure 1, and as the rail is pulled back by the
wires h³ and d, namely, when the signal is set at " line clear" the rail will lie level
with the rail a as shewn at Figure 2.
The device in front of the "home" signal c, is of similar construction, and is
worked in the same way as the device h just described in connection with the
"distance" signal b.
With reference to the drawings (Figures 3 and 4), A designates a locomotive
engine, and B the cab thereof. i is a shoe or brush which is suspended by and
hinged to the rods at the side of and below the frame A' of the engine A. The
normal position of this shoe is inclined as shewn, it is connected by the rod to one
end of the lever which is pivoted on the engine A. The other end of the lever is
provided with a cord m which passes over suitable pulleys into the cab B where it
is connected to a suitable catch m¹ in connection with a weighted lever n. This
lever n is connected by a rod or cord n' to the steam supply valve handle p of the
engine, and, if desired, to the steam whistle handle. These parts.constitute an
example of the parts under our invention adapted to work in connection with the
device above described as arranged near the "distance" signal.
•
⚫s designates a wheel arranged on the end of a rod s supported by and adapted
to slide on a stay fitted on the engine frame. The upper end of the rod s¹ is
connected with or adapted to operate, when raised, the vacuum or other braker on
the engine by means of the lever r¹, and also, if desired, to strike a gong or other
sounding device. These parts constitute an example of the parts under our
invention adapted to work in connection with the device above described, as.
arranged near the "home" signal.

In the operation of our invention the normal position of the "distant" signal,
being the normal position of the device h, is also "on" or raised, and as the
engine A passes over the device h the brush or device i comes in contact with said
device and is raised and thereby releases the catch m¹ and allows the weighted
lever n, by means of the cord n¹, to move over the handle p and thus shut off the
steam, and, if connected, blow the whistle; again as the engine passes over the
device in connection with the "home" signal, the normal position of which is a

page_text: raised one, the wheel's comes in contact with such device and thereby operates the
brake of the engine and train.
The devices and s are so set on the engine that they will only come in contact
with their respective devices on the line.
It will be obvious that when the signals be and the devices are off, as shewn at
Figure 2, the parts on the engine are not operated.
"
With reference to the arrangement of the parts or devices according to our
invention, shewn in Figures and 6, 6 designates the "distance" signal, and c the
'home" signal, g the signal cabin, the lever for working the "distance signal,
and e* the lever for working the "home" signal. The devices are in duplicate,
one on each side of the rails a a¹ at the distance and home signals as shewn. These
devices consist of a bar or rail h sliding within a channel h. The tail end of each
rail has hinged to it a short rail piece h³ which, when the rail h is raised as shewn
in Figure 6, provides an incline for the device on the locomotive when leaving the
rail or when the locomotive is running the reverse way, tender first. The rail h
is raised by the rocking lever ', and is provided with a weighted rocking lever h
to balance the rail, the operating wires h³ and e³ are, in this case, led direct to the
levers d² and e² of the "distance" and "home" signals respectively, in the signal
box 9, and are connected to the levers d² and e² in such a way that when the said
levers are placed to set the signals b or c at danger, the wires h³ or e³ are pulled
and so raise the rails h. The rail devices are provided on both sides of the line
to provide for trains running in the reverse direction. If the connecting wires ³
or should break, the inclined plane or rail h will fall, so that there is no
possibility of its being up when the signal is pulled down.
With reference to the arrangement of the parts or devices, according to our
invention, on the locomotive, as shewn in Figures 7, 8, and 9, the devices that are
worked by the inclined rail A, in this case consist of inclined levers is, provided
with wheels. for making contact with the rails h. These wheels may be tyred
with india-rubber, or made in the form of a circular brush to make the contact
more elastic. The lever i is for working the steam supply valve, and the levers is
for working the brake gear on the engine. The levers is are supported from the
engine frame A' by the stays i The lever i is provided with and works the rod
which works the lever on the engine cab, and thereby withdraws a catch or
stop.m from a weight n³, which is connected, by a cord n', to the steam supply
valve handle of the engine, and, if desired, to the steam whistle. The lever i is
adapted to be worked in connection with the device or rail above described, as
arranged near the "distance" signal. The levers is provided with, and works a
rod which works a lever s³ on the engine cab, and thereby withdraws a catch or
stopt from a weight t¹ which is connected, by a cord u, to a lever u¹, which, when
the weight t¹ is released, works the handle v of the brake gear.
In the operation of the arrangement of our invention last described, when the
"distance"signal 6 is at danger, or on, the device h is in a raised position and as
the engine A passes over it, the wheel or brush j of the inclined lever i comes in
contact with the inclined device, and is raised, and thereby, by means of the rod l
and its gear, withdraws the stop m', and allows the weight n² to fall, which in
falling draws over the steam supply handle p by means of the cord n' and thus
shuts off the steam. When the engine reaches the home signal c, if it is at danger,
or "on," the device in connection therewith, is in a raised position, and as the
engine passes over it the wheel or brush; of the lever s comes in contact with the
inclined device h and is raised, and thereby, by means of the rod s¹ and its gear,
withdraws the stopt and allows the weight t' to fall, which in falling draws over
the lever u¹ by means of the cord u and thereby works the handle of the brake
gear, and applies the brake.
Our invention is particularly adapted for use in dark and foggy weather, as the
signal man can stop a train at the "distance" ог "home" signals independently of
the engine driver, on any emergency that may arise.

page_text: It will be obvious that the contact apparatus can be fitted on any suitable part
of the engine, and outside or inside the rails as desired.
Having now particularly described and ascertained the nature of this inven
tion and in what manner the same is to be performed, we declare that what we
claim is :-
1. The herein described improvements connected with the working of railway
trains in the time of fog or other like and equivalent times, consisting in causing
the steam supply of the engine to be shut off by a contact device in connection
with the rail track, and a contact device in connection with the engine, which
operates, or causes to be operated, the steam supply device, said contact device
being disposed on the track at a point where such steam supply should be shut off;
substantially as set forth.
2. The herein described improvements connected with the working of railway
trains in the time of fog or other like or equivalent times, consisting in causing the
brake to be applied to the train by a contact device in connection with the rail
track, and a contact device in connection with the engine which operates, or sets in
operation the brake, said contact device being disposed on the track at a point
where such steam supply should be shut off'; substantially as set forth.
