We, ARTHUR WILLIAM ELLIS, and SIDNEY ARTHUR PAYNE, both of
Somerset Villas, Fairfield Road, Edmonton, in the County of Middlesex, Glaziers,
do hereby declare the nature of this invention to be as follows:-
The object of our invention is to provide means whereby an engine-driver may
be automatically notified of the approach of a train to a signal at Danger.
In carrying out our invention, we adopt substantially the following arrange-
ments:
Upon the track and centrally or thereabouts between the metals, we place a bar
or rod, same being affixed to the sleepers by means of rocking arms or levers
pivotted thereto so as to allow of its movement.
The bar or rod aforesaid is parallel with the metals and located in such a
position relatively to the signal that the engine driver may have timely warning
of the signal being at Danger when the train arrives at the place where it is fixed.
Upon the engine and in any convenient position underneath the bed-plate
thereof, two or more blades or strips are secured by suitable connections in
communication with an electric bell or alarm worked by a battery on the
engine. In connection with the electric circuit which is completed by the blades
or strips aforesaid coming in contact with the bar or rod on the line, a coloured
disc or discs may be arranged in a box or case in front of the engine driver, say
for instance two discs, one red and the other green. When the train passes over
the spot where the signalling bar is fixed on the line, if the signal is standing at
Danger" the said bar will be raised to its highest position by means of a suitable
connection with the signal wire or rod.
86
If the signal indicates "Line clear," then the bar will be in its lowest position,
and in that case no contact will be made with the apparatus upon the engine. The
arrangements herein described are specially applicable for use in foggy weather,
and will partially or entirely supersede the necessity for employment of detonators
or band signals.
In the event of the engine driver not requiring to keep the apparatus in use
continually, the device attached to the engine may be easily thrown out of action
at any moment.

Improvements in Railway-signalling Apparatus.
We, ARTHUR WILLIAM ELLIS, and SIDNEY ARTHUR PAYNE, of Somerset
Villas, Fairfield Road, Edmonton, Glaziers, 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, indications are automatically given to the engine-
driver when approaching a signal at Danger, by means of an electric circuit

page_text: completed through apparatus upon the permanent way and upon the engine
respectively.
The apparatus upon the permanent way is shewn in the lower part of Fig. 1 in
the accompanying drawings, and consists of a metallic bar a mounted on rocking
levers cc pivoted in bearings bb attached to the sleepers d d.
For the
When the signal is put over to "Danger," the metallic bar a is raised by the
signal wire g acting on the weighted levers g' g³ attached to one end of a rod,
the other end of the rod being attached to one of the rocking levers c.
purpose of this Specification the bar a will be assumed to be situated between
the metals of the permanent way, but with slight modification it could be arranged
alongside the metals.
The part of the invention attached to the engine comprises a contact maker, a
battery or other suitable source of electricity, and an indicator. The contact
maker is shown in the upper part of Fig. 1, and consists of a block or its
equivalent attached to the engine in any suitable manner and having attached
to it, metal strips e e made of spring steel or other suitable metal.
The positive pole of the battery is connected with one of the strips e, and the
negative pole with the other of them. It is intended that the lower ends of the
contact springs shall be so far below the engine frame that when the metallic
bar a is raised to its highest position (by the putting over of the signal to
"Danger "), the lower ends of the springs e e will press against the rod a all the
time the engine is passing over it, and as the springs are respectively positive
and negative, the bar a connecting them for the time being will complete the
circuit.
The indicator itself consists of a base-board on which is fastened an electric
bell m vi of any convenient construction. Above the electric bell we provide an
electro-magnet with the poles pointing upwards. Above the poles of this magnet.
we provide an armature l, in the centre of which and at a right angle thereto we-
attach an arm having at its free end a catch s. We support the arm, armature
and catch on a pivot or the like y passed through the centre of the arm into a
small bracket attached to the base-board. The catch s is intended to be heavy
enough or weighted so as to retain the armature away from the poles when no
current is passing, its distance above the poles being regulated by a screw or the
like x.
The electric bell and the magnet above it are covered in by a lidless box having
on the front of it a space the upper balf R of which is colored red and the lower
half G green. Extending from side to side of this parti-colored space is a spindle
to which is attached a "Hap" colored red on the upper side, and green on the
lower side so that when the flap is turned up, the whole space appears green, and
when turned down the whole space appears red. Above the space is a hole
through which protrudes the catch s by which the "Hap" is retained in position
when turned up. At one end of the spindle of the "flap" is a handle k so arranged
as to stand at a right angle to the "flap."
At the handle side of the box are two strips or tongues of metal
over the other, and fastened to the box at one end by a couple of screws.

laid one
When this flap" is turned up the handle projects beyond the colored space,
but when the "flap" falls, the handle passes between the two strips or tongues of.
metal on the side of the box. On the edge of this side of the box are two metal'
pins, which (when the box is put over the electric bell and the magnet) enter two
metallically bushed holes in the base-board. One of these pins is electrically
connected with the spindle of the "flap," and the other pin is similarly
connected with the lower of the two strips or tongues of netal already
imentioned.
At the top of the base board we provide four terminals numbered 1, 2, 3, and 4
on the drawings No. 1 is electrically connected with a pole of the battery and
also with the upper of the two bushed holes in the base-board into which the
metal pins on the edge of the covering box are inserted. Terminals 2 and 3 are

page_text: connected together, 2 being also connected with the spring of the bell-hammer,.
and also with the second pole of the battery. One end of the coil round the
bobbins of the upper electro-magnet is attached to terminal 1 and the other to
terminal 4. One end of the coil on the bell bobbins is connected with the
platinum pointed screw touching the bell spring and the other end to the second
of the two bushed holes in the base-board. Terminal 3 is connected with one of
the springs e of the contact maker attached to the engine, and terminal 4 to the
other of the springs e.
The box cover is attached to the base-board by hooks on the box, and eyes on
the board, or it may be hinged.
CE
The action of the apparatus is as follows. When the signal is put over to
Danger," the signal wire g will at the same time throw over the weighted.
levers g g and turn the rod and so raise the rocking levers c, and the metallic
bar a.
Assume now that the battery provided on the engine is in working order,.
that the various connections have been made as above described, and that the
flap" on the indicator has been turned up and caught by the catch s. Then
"
when the engine passes over the bar a, the springs e e will press thereon and the
bar will complete the circuit, whereupon the magnet / will draw down the armature l
and raise the catch s, thus allowing the "flap" to fall and expose the red colored
portion of the upper part of the front of the box and the red colored upper and.
now outer part of the "flap."
The driver thus has ocular warning that the signal is at Danger. Besides this,
the falling of the "flap" forces the handle k between the tongues
on the
side of the box, the bell circuit being thus completed the bell rings, and
thus affords oral in addition to the ocular warning of the signal being at
Danger.
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
