Electric Communicator for Use as a Means of Communication between
Passengers and Guards or Drivers of Trains.
GEORGE ARMSTRONG, 1, Kendal Street, Carlisle, Pay Clerk in Biscuit Factory,
do hereby declare the nature of this invention to be as follows:-
Viz. COMMUNICATION BY ELECTRICITY.
The electric current to be generated by a dynamo on engine or by batteries.
on engine and van.
I purpose using the two outside couplings, there are three couplings attached
to all vans & carriages, as transmitters of the current & to form the circuit.
The wires will run from battery in van to van couplings when the couplings
will take the place of the wires to convey the current to the wires in the adjoin-
ing carriage & so until the carriage is reached adjoining the engine & there being
only one coupling on engine, I purpose continuing the current to the engine
by means of the wires from the battery on engine which will have a spring hook
to attach to the wires which are connected to the couplings of the carriage adjoin-
ing the engine. This will be the only hooking or unhooking required on the
whole train as when any of the carriages are coupled or uncoupled to each
other or to the van the current is at once complete or broken.
For passengers to communicate with either driver or guard there is an arrange-
ment in each compartment with an indicator to locate the compartment from
which the bell has been rung.
The couplings not being insulated there might be slight danger of a shock
to the person coupling or uncoupling the carriages. To avoid this there is an
arrangement on engine or van so that when train is stopped the current can be
cut off automatically or otherwise.

GEORGE ARMSTRONG, 1, Kendal Street, Carlisle, Pay Clerk in Biscuit Factory,
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:-
-

page_text: purpose using the two outside couplings b (there are three couplings attached
to all vans & carriages,) as transmittors of the current & to form the circuit.
The wires c will run from battery a in van to van couplings b when the coup-
lings will take the place of the wires e to convey the current to the wires in
the adjoining carriage & so until the carriage is reached adjoining the engine
& there being only one coupling on engine I purpose continuing the current to
the engine by means of the wires c from the battery a on engine which will
have a spring hook to attach to the wires c which are connected to the couplings b
of the carriage adjoining the engine.
This will be the only hooking or unhooking required on the whole train as
when any of the carriages are coupled or uncoupled to each other or to the van
the current is at once complete or broken.
The couplings not being insulated there might be slight danger of a shock
to the person coupling or uncoupling the carriages.
To avoid this there is an arrangement (a switch) on engine or van so that
when train is stopped the current can be cut off.
For passengers to communicate with either driver or guard there is an arrange-
ment E in each compartment whereby passengers wishing to communicate with
driver or guard of train are requested to pull the switch handle into a vertical
position which puts the wires in contact & thereby rings the bell, this motion
at the same time locates by means of indicator F the compartment from which
the bell has been rung as switch E being connected to indicator F by means
of the spindle K which passes from inside of carriage to outside through wood-
work of same.
The accompanying drawings show
Fig. 5, to represent a portion of van H & carriage I with couplings b attached,
this also shows the wires C as attached to couplings by means of terminals D
& the indicator F.
Fig. 1, represents the switch E as seen inside of carriage with wires connected.
Fig. 2, is a section showing spindle K as passed through side of carriage with
indicator on outside.
Fig. 3, is showing indicator F as seen on outside of carriage.
Fig. 4, is a diagram showing battery A connected with bell G by means of
line wires, also wires passing from battery A & bell G to terminals 1) by which
they are fixed to couplings they then go from couplings along carriage to
switch E, Fig. 1, where the contact is made by means of the handle being pulled
into a vertical position & so along the train; the circuit being formed by pulling
the handle in any compartment.
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
1st The use of the couplings as a means of transmitting.
2nd The use of electricity as a means of communication between passengers
& guards or drivers of trains.
