This Invention relates to a method by which drivers and others in charge of trains
may know the position of the signals when they are not discernible to the eye either
through fog or in case of the lamp being out, obscured by snow, signal pole, broken
or otherwise disarranged.
In a groove made for the purpose in the guards in front of the engine on both
sides is fixed a perpendicular flat bar of iron with lower end of steel and bevelled.
This bar is moveable and when lowered for use the bevelled end is one inch above
the metals and it extends upwards to a convenient spot say two feet above the buffer
beam, where it is connected with a horizontal rod which extends along the engine
and through a hole in the iron plate just clear of the look out window.
This end of
the rod works a hammer on a binge which in turn strikes a bell when the rod comes
back by the perpendicular bar being pushed up by means herein after described. This
takes place on both sides of the engine at once so that should the driver fail to notice
his bell being struck the fireman would not be likely to do the same.
The method by which the moveable bar on the engine is forced up, is under direct
control from the signal box.
The wire (or rod as the case may be) which works the present standing signal is
extended as far as is necessary in the direction for which the signal is intended. The
wire (or rod) works another rod or shaft running across at right angles under the
metals, this latter rod is properly carried in bearings and the end to which the lever
and wire is attached is also fitted with a weight and lever which reverses the action of
the wire when the latter is slackened from the signal box.
When the signal is brought to danger the shaft under the metals raises an inclined
plane above the top of the metals to a height of about three or four inches. A
groove is made in the metals say about 18 inches long 1 inch broad and inch deep,
in this groove is fitted a steel plate having a joint in the middle which connects the
two halves with a pin which goes through a perpendicular hole in the metals, this pin

page_text: is pushed upwards by a long spring connected with the shaft and when so raised the
plate forms a double inclined plane. When the signal stands at line clear the inclined
planes are drawn down level with the metals by this same pin acted on by the shaft
which is partially turned round by the lever, connected with the wire.
The spring which pushes up the pin and inclined plane is made stiff enough to
resist the pressure of the bevelled bar on the engine and so the bell is struck by the
bar being forced upward as before explained. But when the weight of the train
comes to the steel plates of the inclined planes they go down into the groove prepared
for them, leaving no obstacle in the way of the train. Should the train be going
over the signal very slowly the spring moves up and down thus avoiding the wear
and tear of the weight lever being disturbed. Or instead of having the inclined
planes on the top of the metals they may be close by the side but in both cases the
incline acts on the bar in front of the engine and gives the driver the signal in the
same way.
The inclined plane is made double so that a train may be backed over it or in case
of a single line trains may run both ways. In either case whether the inclined plane
is on the top or by the side of the metals the same broom on the engine which sweeps
the snow from the metals sweeps it off the inclined planes.
It will generally be best to place the incline at a little distance from the usual
signal so that when the driver, lears the bell he can slacken up until he comes to the
signal pole and there wait for the signal of line clear.
If in settled fine weather it is thought best to disconnect the signals this can be
done by unshackling the wire at the signal pole, but leaving all ready for immediate
use if the weather changes.

page_text: I, EDWARD CLIFFORD TURNER of Blakeney, Norfolk, Merchant, 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 :-
This invention relates to a method by which drivers and others in charge of trains
may know the position of the signals when they are not discernible to the eye either
through fog or in case of the lamp being out, obscured by snow, signal pole broken or
otherwise disarranged.
In guides fixed for the purpose in the guards in front of the engine on both sides
is fixed a perpendicular bar or rod of iron with lower end of steel and bevelled.
This bar is moveable and when lowered for use the bevilled end is a short distance
above the level of the metals and a little on the loft hand of each. The bar extends
upwards to a convenient height and by a bell crank it is connected with a horizontal
rod which extends along the engine and through a hole in the iron plate just clear of
the look out window. This end of the rod works a haminer on a hinge which in
turn strikes a bell when the rod comes back by the perpendicular bar being pushed up
by means hereinafter described. This takes place on both sides of the engine at once
so that should the driver fail to notice his bell being struck the fireman would not be
likely to do the same.
The method by which the moveable bar on the engine is forced up, is under direct
control from the signal box.
The wire (or rod as the case may be) which works the prosent standing signal is
extended as far as is necessary in the direction for which the signal is intended. The
wire (or rod) works another rod or shaft running across at right angles under the
metals, this latter rod is properly carried in bearings and the end to which the lever
and wire is attached is also fitted with a weight and lever which reverses the action of
the wire when the latter is slackened from the signal box.
When the signal is brought to danger the shaft under the metals raises an inclined
plane above the level of the metals to a height of about three or four inches. The
inclined plane consists of a steel plate having a joint in the middle.
The jointed
plate is pushed upwards by a weight acting on an arm working an eccentric on the
shaft and when so raised the plate forms a double inclined plane. When the signal
stands at line clear the inclined planes are drawn down level with the metals by
this same arm on the shaft which is partially turned round by the lever, connected
with the wire.
The weight which raises the inclined plane is heavy enough to resist the pressure of
the bevelled bar on the engine and so the bell is struck by the bar being forced upward
as before explained.
The

same broom on the engine which sweeps the snow from the metals sweeps it off the
inclined planes.

page_text: It will generally be best to place the incline at a little distance from the usual signal
so that when the driver hears the bell he can slacken up until he comes to the signal
pole and there wait for the signal of line clear.
In order that my said invention may be fully understood and readily carried into
effect I will proceed to describe the drawings hereunto annexed.
DESCRIPTION OF THE DRAWINGS.
Figure 1 is a sido elevation of the apparatus and shows the engine approaching the
raised inclined planes.
Figure 2 is front elevation of the same.
Figure 3 shows to a larger scale the parts forming the inclined planes and the parts
in connection therewith. a a are the steel plates they are jointed together at B and C
one end is jointed to the bearing plank or plate D. The other end at E slides freely
on the said bearing plank or plate. F is a rock shaft passing across under the metals,
it carries the curved lifting lever G. His an arm fixed on the shaft F, it has a curved
horn and the wire J passing to the signal box lies along the horn and is made fast near its
root. The lever carries a weight K. sufficiently heavy to maintain the inclined plane
in position but not too heavy to be raised by the wire passing to the signal box when
the inclined plane is to be lowered out of the way.
Lis the vertical bar on the engine carried by the guard and sliding upwards when
it meets the inclined planes. Mis the horizontal bar to which the bar L is coupled
by a bell crank lever. The further end of this rod acts against the bell trigger.
Springs in connection with the bar M hold the bar L down in position to operate.
The bar M can however be drawn back and locked to put the apparatus out of use.
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 combination of apparatus substantially as described consisting of the jointed
plates a a forming when raised a double incline plane and apparatus for operating the
said inclined plane so as to raise it in the path of a bar carried upon the engine
which thereby is moved and made to operate upon a bell or signal as herein set
forth.
2. Railway signalling apparatus substantially as described and illustrated by the
annexed drawings.
