We, GEORGE PETER DINEEN of 1* Lansdowne Road Tottenham in the County of
Middlesex Printer and ARTHUR ROWE of 203 Peckham Rye in the County of
Surrey Warehouseman do hereby declare the nature of this Invention to be aš
follows:-
According to this Invention we work the points and signals from the front and
the rear of the train itself by means of suitable projecting fixed parts which con-
secutively come in contact with corresponding movable or shifting parts arranged'
by the side of the line and connected to the bar for shifting the points and for
working the signals. As an example we provide the engine and the break van at
the rear of the train which is intended to turn off at a certain branch line with
a horn or bar and we connect the bar for shifting the points for a branch line with
a lever or other shifting or moving part which is arranged by the side of the main
line at a suitable distance from the branch line points so that the aforesaid horn or
bar on the engine as it passes by comes in contact with and shifts the first named
lever or moving part whereby the points are thrown over so as to open to the branch
line. The branch line train is thus properly and automatically guided onto the
branch line, and the horn on the brake van when the latter has quite passed the
points comes in contact with a lever or other shifting or moving part arranged by
the side of the branch line and also connected to the points whereby these are,

signal post or posts so that the shifting of the points also works the signals to
shew main line clear branch, line closed and vice versa. It will be understood
that the trains for the main line are not provided with horns or projecting parts
for moving the points, but they are fitted with projecting horns or parts which
although not arranged to come in contact with the aforesaid points and signal
gear yet are adapted to come in contact with and work other levers or moving or
shifting parts which are so connected with other signals as to work them to close
one signal after another as the train passes same and to open the preceding one.
It will also be understood that where there are two or more branch lines the
movable parts for working the points and signals are arranged in different positions;

branch line train. while being unaffected by any other. The signals may be
telegraphically connected in the home signals or station so as to indicate the
position of the train autómatically.
It will thus be seen that the train signals itself and works its points.
Signals on Railways and Tramways.
We GEORGE PETER DINEEN of 14 Lansdowne Road, Tottenham, in the County
of Middlesex, Printer, and ARTHUR ROWE of 203 Peckham Rye in the County of
Surrey, Warehouseman 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 this invention we work the points and signals from the front and
the rear of the train itself by means of suitable projecting fixed parts which
consecutively come in contact with corresponding movable or shifting parts
arranged by the side of the line and connected to bars for shifting the points and
wires or bars for working the signals, such projecting fixed parts being set in fixed
positions before the trains start from the terminus. We thus do away with the
necessity for signalmen and pointsmen except at a terminus.
As an example we will describe the invention with reference to the accompanying
drawings in which Figure 1 is a plan of main and branch line points with automatic
gear for working same and the signals, and Figure 2 a side view, Figure 3 a plan
view of main or branch line block system, and Figures 4 and 5 side view and end
view of the automatically actuating parts on the train and on the line. We
suppose for example that the upper line Figure 1 is the down line. We provide
the engine at the front and the brake van at the rear of the train which is
intended to turn off at a certain branch line with a horn or bar such for instance
as a Figures 4 and 5 which has a slot for receiving one or more projecting pegs.
Such a peg b fixed in the horn a on the brake van in the rear will come in contact
with and shifts into the dotted position the lever A Figure 1 which by wire or
rod B, bell crank lever C, wire or rod D, bell crank lever E, and wire or rod F
work the main up signal G turning it into the up or danger position. To the bell
crank lever E is also connected a wire or rod H which is connected with a lever I.

page_text: which thereby is shifted into the dotted position. It must here be noted that the
shifting lever A is placed a sufficient distance in advance of the branch line points.
A peg on a horn on the engine which peg is placed at another level than the peg b
on the brake van next comes in contact with and shifts into the dotted position
the lever H which by means of the levers d and e and rods g fand c shifts the
points for and open the branch line. These levers or shifting or moving parts are
arranged by the side of the main line at a short distance from the branch line
points and at such a level that the peg on the aforesaid horn or bar on the engine
as it passes by comes in contact with and shifts the lever h. The branch line
train is thus properly and automatically guided on to the branch line and the
aforesaid projecting peg b fixed in the horn on the brake van will when the brake
van has quite passed the points come in contact with a lever k or other shifting or
moving part arranged at the proper level by the side of the branch line, and also
by bell crank levers and d and rods fand n connected to the points whereby
these are shifted back to their original position so as to leave the main line clear.
The same peg on the brake van horn next comes in contact with and moves the
lever I which by means of the wire or rod H, lever E, and wire or rod F is carried
up to the main up line signal post G and lowers the arm to clear. It will thus be
understood that with the shifting of the points the signals are also worked to
block the main up line clear until the branch line down train is perfectly clear of
the crossing on the up line.
For a branch line train coming in the opposite direction similar signal and point
shifting levers and gear are arranged viz. the peg on the rear brake van shifts the
lever A which by wire or rod B¹ puts the rear main up line signal K to danger,
and also by bell crank lever C₁, and wire or rod D¹ shifts the lever I into the
dotted position. The lever h¹ is next by the peg on the engine turned into the
dotted position whereby through the rods g¹ f¹ and c¹, and the levers e¹ and the
points are shifted and opened for the branch up train to proceed on to the main up
line. The continuation of the rod f¹ is by lever and rod n¹ connected to a
shifting lever which is brought into the dotted position, but is by the peg on the
brake van brought back into its former position thus closing the points to the
branch line when the train has fully passed the points. Next the peg on the brake
van comes in contact with the lever I pushes it out and through the wires or
rods F D and B¹ and the levers E¹ and C¹ shifts the shifting lever A¹ in and
lowers the main line rear signal K. A main line up train coming along will next by
means of a peg fixed similarly on its brake van shift the lever S which by wires or
rods R and O and lever Q shifts the double signal P to danger thus blocking both
branch lines. The same peg will next shift the lever L and by the wires or
rods M and O and the bell crank N lower the double signal P.
It will be understood that the trains for the main line are not provided with
horns or projecting parts for moving the points, but a peg on a brake van comes in
contact with and works other levers or moving or shifting parts which are so
connected with other signals as to work them to close one signal after another as
the train passes same and to open, the preceding one. Referring thus to Figure 3
which represents parts of a main line (or it may be a branch line but not
immediately at the points) and assuming that the peg on the horn on the rear
brake van of an up train has pushed back the shifting lever T thus by means of
wires or rods t and u and lever v raising the signal No. 1 to "Danger" and
by means of the wires or rods tu and x and levers v and to simultaneously moving
forward the shifting lever U. The same peg on the brake van will, when the
train has advanced some distance, shift the lever V into the dotted position
whereby through the wires or rods 1. 3 and 5 and levers 2 and 4 the shifting
lever W will be brought into the dotted position and the signal No. 2 be raised to
"Danger." The peg next shifts the lever U into the dotted position whereby
through the wires or rods x and u and levers v and w the No. 1 signal is lowered
to "Clear" for a train in the rear to proceed as far as to No. 2 signal.
The peg
next shifts the lever W out into the position shown whereby through the wires or

page_text: rods 5 and 3 and levers 4 and 2 the lever V is returned to its in position and the
signal No. 2 is lowered. This system is repeated throughout the length of the line
and is also similarly shown here on the opposite or down line. This part of the
system may also be applied to the branch lines. It will also be understood that
where there are two or more branch lines the movable parts for working the points
are arranged in different positions relatively but so as to correspond each with the
projections or horns on its proper branch line train while being unaffected by any
other. The signals may be telegraphically connected in the home signals or station
so as to indicate the position of the train automatically.
It will thus be seen that the train automatically blocks the line in rear and as
regards a branch line works its points.
:
In case of several branches from the same main line or from a branch line it
will be understood that the engine is to be fitted with pegs at different levels
corresponding with the shifting levers that have to be moved. It will be noticed
that all the shifting levers A h k etc. are shown so long that the actuating pegs
hold them in position sufficiently long after being moved as to counteract the effect
of
any vibration.
Having now particularly described and ascertained the nature of our said
invention and in what manner the same is to be performed we declare that we
do not specifically or separately claim any mechanism hereinbefore described and
shown, but we claim :
The automatic switching and signalling system consisting in a projecting peg
or part on the engine and rear, brake van for a branch line train in combination
with a shifting part A which by suitable connections works a main up line
signal G and by suitable connections from the latter works a shifting part I for
re-setting the said signal which is effected by the peg on the brake van at the rear
of the train, and in combination with a projecting peg or part on the engine and
with a shifting part h which by suitable connections shifts and opens the points
for the branch line train which points by suitable connections therefrom to a
shifting part k are closed again by a peg on the brake van coming in contact
therewith and in combination with the shifting parts T. V U and W which by
suitable connections work block signals from the train itself by means of the
aforesaid peg on the rear brake van so that a branch line train automatically opens
and closes its switches and works the signals for branch and main line at the
points and so that the train whether on branch line or main line works its own
block signals substantially as described and shown.
