PROVISIONAL SPECIFICATION.
Improvements in and connected with Railway Signalling.
We, JOHN DAY, of 47 Salisbury Road, Armley, in the City of Leeds, Mechanic,
and CHARLES EDMUND TAYLOR, of Osmandthorpe, near Leeds, Railway Guard,
do hereby declare the nature of this invention to be as follows:-
Our invention has reference to improvements in and connected with railway-
signalling.
The object of our invention is to provide improved apparatus for signalling on
railways so as to prevent collisions by giving an audible signal which is done by
acting upon the whistle of the engine, or by ringing a bell upon such, cr by sounding
a gong, or operating a buzzer; or by giving a visual signal upon the engine in
front of the driver.
Our invention for the said object combines mechanical and electrical apparatus
which can be used either separately or combined and can be operated either by the
train or by the signal-man.
Our invention can also be arranged to shut off steam and put the brake on
automatically, if required.
In carrying out our invention we employ blocks, inclines, or wheels secured to
lever arrangements, connected to wires, tubes, or rods, communicating with the
signal levers. The said blocks, inclines, or wheels are drawn to the sides of the
rails either by the signal-man or by the action of a train.
When the signal man puts the signal at danger, the blocks, inclines or wheels,
are brought into position against the rails, and act upon a wheel or runner which
is connected to and moves a sliding rod on the engine frame.
This sliding rod is connected so as to act on the whistle and give an audible
signal, which is stopped by the engine driver by means of a spring rod which
ates as a catch and engages with the sliding rod, this refers to the mechanical
action.
For the electrical action, bells are rung, or gongs are sounded by means of the
sliding rod being connected to a switch or cut off composed of an arm to which one
of the wires is connected and a spring stud or bolt to which the other wire is
connected.
The said wires are connected to a battery, as ordinary.
On the lifting of the sliding rod by the action of the runner upon the blocks,
inclines, or wheels, the said arm comes in contact with the spring stud or bolt and
completes the circuit, so ringing a bell or gong.
At a suitable position from the signal is hinged or pivotted to the rail a depression
plate connected to a wire secured to a rod which moves the signal arm, so that
when the train has passed the signal, it puts the signal arm to danger and the
blocks, inclines, or wheels, which can only be pulled off by the signal-man.

page_text: Fig. 1, is a side elevation showing our invention applied, the block acting upon
the runner
on the engine and the electric circuit established as hereinafter
explained.
Fig. 2, is a plan, showing blocks or inclines in position for acting upon the
runner or wheel on the engine, as when the line is signalled "at danger."
Fig. 3, is a further plan, showing blocks or inclines out of position for clearing
the runner or wheel on the engine, as when the signal is given "line clear."
Fig. 4, is a side elevation showing depression plate or lever (at the side of the
rail) operated by the train, as hereinafter explained.
In carrying out our invention we employ blocks or inclines A secured to lever
arrangements B connected to wires, tubes, or rods C communicating with the
signal levers. The said blocks or inclines A, are drawn to the sides of the rails D
by the signalman, and may run on wheels, or slide upon a suitable foundation.
When the signal man puts the signal at danger the blocks or inclines A are
brought into position against the rails D, see Figs. 1, and 2, and act upon a wheel
or runner E, which is connected to and moves a sliding rod F, supported on the
engine frame G.
This sliding rod F is connected so as to act on the whistle, or preferably on a
whistle or buzzer H upon the frame G, by means of the arm G', and give an
audible signal, which is stopped by the engine driver, by means of a spring rod J
which acts as a catch and engages with the sliding rod F. This spring rod J is
withdrawn by means of a weighted lever T, pivotted at U, and connected to the
rod J by means of a short cross-rod working in the slot V.
The runner E can also be connected to a radius arm or lever O pivotted to the
engine frame G, and enclosed by a suitable cover P.
H' is the steam pipe to the whistle H, and H2 is the cock for shutting off steam,
when required, R is a cover for enclosing the sliding rod F, the spindle end F¹ of
which passes through the top of the said cover, and acts as a guide for the move-
ment of the said rod, which is assisted on its downward movement, (when the spring
catch J is withdrawn and the runner or wheel E is clear of the block A) by the
spring F carried on the spindle F'. This refers to the mechanical action.

page_text: For the electrical action bells are rung or gongs are sounded upon the engine by
means of the sliding rod F being connected to a switch or cut-off composed of an
arm K to which one of the wires L is connected and a spring stud or bolt M to which
the other wire N is connected. The said wires are connected to a battery, and to
the bell or gong as ordinary.
S is a cover for enclosing the electric switch or connection.
On the lifting of the sliding rod F by the action of the runner E upon the
blocks or inclines A, the said arm K by means of the projection K' upon the rod F
comes in contact with the spring stud or bolt M and completes the circuit, so ringing
the bell or gong. On the lowering of the said sliding rod F as before set forth the
electric circuit is broken, and the bell ceases to ring.
The sliding blocks A work in boxes A¹ carried on sleepers and are guided therein
by the guide pieces A³, and may work on wheels or runners, if required.
The said boxes are also provided with a covering A³, by which the blocks A
can be enclosed and kept from snow and dirt, and a lamp, if required, for heating
the parts in a keen frost and preventing the blocks or inclines being frozen fast.
At a suitable position from the signal there may be hinged or pivotted to the
rail D or to a support D' upon the track, a depression plate or lever D' having a
finger D³, coming in contact with a bell crank lever D pivotted to the rail D.
Connected to the said bell crank lever D is a wire D' passing to a bell crank
lever De fixed upon the track and connected to the lever mechanism B, 80
that when a train has passed the signal, the depression plate or lever D³, (by
the action of the flange of the wheel of the engine upon such plate or lever), puts
the signal arm to danger, and the blocks or inclines to correspond therewith, by
causing the said finger D³ to turn the bell crank lever D' upon its centre, thus
drawing forward the wire D' which actuates the bell crank lever D, and operates
the lever mechanism B, so as to put the signal arm at danger, and the blocks or
inclines A to correspond therewith, which can only be pulled off by the signal-man.
The bell crank lever D is slotted at the part connected to the lever mechanism B,
to adjust itself to the movement of such.
D' is a weighted lever to assist in bringing the depression plate or lever D³ to its
operative position above the rail D.
Our said invention may also be used for signalling when men are engaged repairing
the line by connecting a hand lever to operate the levers B from the side of the
line and control the sliding blocks or inclines A. In this case there would be no
connection with the signal cabin, but the sliding blocks or inclines A and levers B
for operating such could be temporarilly laid at any part of the line where
required.
The mechanical arrangement may be used independently of the electric arrange-
ment, or they may be used together. Or steam may be shut off from the buzzer or
whistle H and the electric arrangement used only for signalling.
Having now particularly described and ascertained the nature of our said inven-
tion and in what manner the same is to be performed, we declare that what we
claim is :-
―
1. In railway signalling, the use of sliding blocks or inclines arranged at the sides
of the rails and operated from the signal cabin simultaneously with the signal, such
as and for the purposes set forth.
2. In railway signalling, the use of sliding blocks or inclines arranged at the sides
of the rails and operated by means of a hand lever from the side of the line,
substantially as and for the purposes set forth.
3. In railway signalling, the combination of sliding blocks or inclines A connected
through lever mechanism B to the signal lever, so that the said blocks or inclines A
can be brought to the sides of the rails D, to operate a runner or wheel E upon a
passing engine or vehicle and thereby cause a sliding or movable rod F to operate
upon a buzzer or whistle, substantially as and for the purposes set forth.
4. In railway signalling, the combination of sliding blocks or inclines A connected

page_text: through lever mechanism B to the signal lever so that the said blocks or inclines A
can be brought to the sides of the rails D, to operate a runner or wheel E upon a
passing engine or vehicle, and thereby cause a sliding or movable rod F to establish
electric circuit between an arm K and a spring stud or bolt M, substantially as and
for the purposes set forth.

5. In railway signalling, the combination of sliding blocks, or inclines A, lever
mechanism B, runner or wheel E, rod F, arm G', whistle or buzzer H, and spring
rod J with lever T, substantially as and for the purposes set forth.
6. In railway signalling, the combination of sliding blocks or inclines A, lever
mechanism B, runner or wheel E, rod F with projection K', arm K, spring stud or
bolt M, and spring rod J with lever T, substantially as and for the purposes set
forth.
