Improvements in or connected with Railway Points and Signals.
FREDERIC BARRY STANTON Engineer 11 Queen Victoria Street London, E.C.
do hereby declare the nature of this invention to be as follows:-
My invention relates particularly to signals in connection with self acting
tumblers or switch boxes, by the combination of which passing trains may hoist
their own signal when a siding is situated in connection with main line or when
a train backs into a siding fouling the points which have been closed, as instead
of breaking or straining the switch rod, as is the case in ordinary switches, the
pressure of the flange of the wheel against the blade of the switch causes it to
open, thus reversing the points and at same time raising the signal, and shewing
that the points have thus been set wrong.
Having stated the object of my invention I will proceed to describe the means
by which I accomplish it.
In switch boxes where the arrangements admit of the tumbler being reversed
by the action of the flange of the tyre pressing against the blade of the switch
I alter the shape of the bell crank by casting welding or otherwise fixing thereto
a quadrant struck from the centre pin and supplied with teeth which engage with
other teeth in another quadrant or wheel or its equivilent fixed at a convenient
distance from the side of the switch box but preferably connected thereto by
means of a projection or projections therefrom forming a base plate which plate
carries the second quadrant or toothed wheel which is connected to a standard or
column forming the signal post which revolves therewith when acted upon by the
first named quadrant when set in motion by the moving of the switch or I may
adopt a series of wheels or quadrants so as to obtain the required action.
If more convenient I may fix the quadrants or toothed wheels to the horizontal
pin in tumbler handle and so get the action onto the signal column by bevil cog
wheels or their equivilent.
This invention applies particularly to switch boxes having toothed gearing or
other arrangements by which the tumbler has a continuous hold of the points and
signals.
Dated this 3rd day of July 1895.

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 particularly relates to signals in connection with self acting
tumblers or switch boxes by the combination of which passing trains may hoist
their own signals when a siding is situated in connection with main line or when a
train backs into a siding fouling the points which have been closed, as instead of

breaking or straining the switch rod as is the case in ordinary switches, the
pressure of the flange of the wheel against the blade of the switch causes it to
open thus reversing the points and at same time raising the signal and shewing
that the points have thus been set wrong.
Having stated the object of my invention, I will proceed to describe the means
by which I accomplish it and in order that my invention may be fully understood
I append hereto a sheet of drawings illustrating the method of carrying my
invention into practical effect.
In switch boxes where the arrangements admit of the tumbler being reversed by
the action of the flange of the tyre pressing against the blade of the switch I alter
the shape of the ordinary hell crank E by casting, welding, or otherwise fixing
'thereto a quadrant J. struck from the centre pin K and supplied with teeth which
engage with other teeth in another quadrant or wheel L. or its equivalent fixed
at a convenient distance from the side of the switch box A. but preferably
connected thereto by means of a projection or projections M therefrom forming a
base plate F which plate carries the second quadrant or toothed wheel L which is
connected with a standard or column C forming the signal post and which revolves
therewith when acted upon by the first named quadrant J when set in motion by
the moving of the switch or I may adopt a series of wheels or quadrants or levers
so as to obtain the required action.
If more convenient I may fix the quadrant J or toothed wheels to the horizontal
pin N in tumbler handle B, and so get the action onto the signal column C by
bevil cog wheels or their equivalent.
This invention applies particularly to switch boxes having toothed gearing or
other arrangement by which the tumbler has a continuous hold of the points and
signals.

Fig. 2 shews plan of switch box.
A is switch box B handle C signal column or pillar D signal E bell crank
F base plate G bracket H sleeper with switch box bolted thereto.
Having now particularly described and ascertained the nature of my said inven-
tion and in what manner the same is to be performed I declare that what I
claim is
An automatic or self acting signal connected with switch boxes substantially as
and for the purpose specified.
Dated this 3rd day of April 1896.
