page_text: Improvements in Electric Locomotives.
I, JEAN ÉMILE AMEN, of 2, Rue de Belgique, Nice in the Republic of France,
Engineer, do hereby declare the nature of this invention to be as follows :-
My invention relates to improvements in locomotive engines to be driven by the
agency of electricity.
Externally, the improved locomotive resembles an ordinary six-wheeled first-
class railway carriage, but pointed at each end to reduce the pressure of the air
when travelling quickly, the points being provided with revolving helical fans set
in revolution by suitable gear from the central axle, and serving to break up and
divide the column of air opposed to the movement of the engine.
The carriage is fitted with windows and blinds in the usual way, and the pointed
ends are also provided with small windows through which the road can be seen.
Ventilators are arranged in the roof.
The carriage is carried on an iron frame with the intervention of indiarubber
blocks, and the usual springs and axleboxes are provided. Both ends being alike,
it can travel in either direction indifferently without being turned round, and two
men are sufficient to attend to it. Of the three axles the outer ones have moveable
bogie carriages, or equivalent means to enable the carriage to pass round curves
of short radius.
Two electro-motors are fixed upon the central axle, the gear by which the helical
vanes already described are driven being situated between them.
Brakes are
provided operated by air compressed by pumps driven by electricity and the
carriage is lighted when required by a sufficient number of electric lamps, supplied
by an accumulator when the locomotive is not in action.
An electric generator, or dynamo, is driven by the electro-hydraulic motor
hereinafter described, by means of a belt, the electricity produced serving to charge
a sufficient number of accumulators. The electro-hydraulic motor consists of a
set of small pumps, driven by cranks upon a shaft caused to revolve at a sufficient
speed by an electro-motor fixed upon it, the small pumps supplying water under
pressure to larger ones, the greatly increased power of which is transmitted by
connecting rods from their plungers to a crank shaft provided with a flywheel, by
which the dynamo is driven as above described, the accumulators being charged
from it, and the electricity from them in turn serving to actuate the electro-
motors on the driving axle of the locomotive. Starting and reversing devices, or
switches, of any of the well-known kinds, are used.
In order to operate the apparatus described, the accumulators are first charged
from any suitable source. When once charged they are used to drive the electro-
motor which itself drives the smaller set of pumps which transmit their motion by
the pressure of the water to the larger set of hydraulic cylinders, which in turn
operate a dynamo the electricity from which drives the electro-motors upon the
axle of the locomotive and also serves to re-charge the accumulators as they become
discharged.
A whistle may be arranged, operated from the compressed air reservoir by which
the brakes are worked.
The hydraulic cylinders being entirely filled with water work perfectly smoothly
and without shock.
Cocks or valves are provided by which any deficiency of water is made good.

In the electro-hydraulic motor, the crank which drives the three smaller
plungers carries the electro-motor which drives it and which is itself supplied from
the accumulators and revolves at about 150 to 20 revolutions minute.
per
crank shafts are of the ordinary kinds used for three cylinder expansion engines.
The frame which carries them consists of an upper part provided with bearings
for the crank shafts, and connected by four columns to the base upon which the
three large and three small cylinders are placed.

I, JEAN ÉMILE AMEN, of 2, Rue de Belgique, Nice, in the Republic of France,
Engineer, 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, and accompanying drawing, that is to say :—
My invention relates to improvements in locomotive engines to be driven by the
agency of electricity.
The accompanying drawing is in illustration of my invention, Figure I being a
side view of a locomotive, partly in section, and Figure 2 a side view of the
pumps.
Externally, the improved locomotive resembles an ordinary six-wheeled first-class
railway carriage, but pointed or conical at each end to reduce the pressure of the
air when travelling quickly, the points being provided with revolving helical fans b,
of aluminium or other metal, set in revolution by bevilled toothed wheels d and
suitable gear from the central axle, and serving to break up and divide the column
of air opposed to the movement of the engine.
The carriage is fitted with windows and blinds in the usual way, and the pointed
ends are also provided with small windows through which the road can be seen.
Ventilators are arranged in the roof.
The carriage is carried on an iron frame with the intervention of indiarubber
blocks e, and the usual springs and axleboxes are provided. Both ends being
alike, it can travel in either direction indifferently without being turned round, and
two men are sufficient to attend to it. Of the three axles, the outer ones have
moveable bogie carriages, or equivalent means to enable the carriage to pass round
curves of short radius. The adhesion to the rails is increased by the passage of
electricity escaping from the electro-motors.
Two electro-motors are fixed upon the central axle, the gear by which the helical
vanes already described are driven being situated between them. Brakes are
provided operated by air compressed by pumps driven by electricity, and the
carriage is lighted when required by a sufficient number of electric lamps, supplied
an accumulator when the locomotive is not in action.

The interior of the locomotive consists of an electric generator, or dynamo C,
driven by the electro-hydraulic motor B (Figure 1) hereinafter described, by means
of a suitable belt, the electricity produced serving to charge a sufficient number
of accumulators D. The wheels of my locomotive are about 130 centimetres
diameter, and revolve about 17 times in a second with 1500 horse-power, giving
an average speed of 200 kilomêtres an hour, and a maximum of about 252 kilo-
metres. The electro-hydraulic motor depends upon the principle of the hydraulic
press of Pascal, but the lever of the small piston or plunger is driven by an
eléctro-motor. It consists of a set of pumps, provided with pistons or plungers,

page_text: driven by cranks upon a shaft caused to revolve at a sufficient speed by an electro-
motor fixed upon it, the small pumps of which three are shewn, I, I, I, supplying
water under pressure to larger ones, I, I, I. For instance, the small cylinder I¹
transmits its power to the large cylinder I. The cylinders being entirely filled
with water or other liquid, there is no shock, and the smaller cylinders are provided
with cocks by whi fluid to supply loss by evaporation or otherwise can be supplied
under the pistons or plungers when at the top of their stroke. The crank shaft
which drives the pistons or plungers in the small cylinders carries on its centre
the electro-motor H, which drives it and is supplied with electricity from the
accumulators, revolving at a speed of 150 to 200 revolutions a minute. The two
crank shafts resemble those ordinarily used in triple expansion engines. An upper
frame carries their bearings and is supported on four columns fixed in a base
supporting the cylinders the passages for which are contained in the base. The
cylinders are of cast iron or brass and the flywheel L is about 80 centimêtres
diameter.
The motor may be used separately in a workshop to replace other motors, and
has the advantage that it may be used for lighting, since it must drive a dynamo
to supply the accumulators.
The greatly increased power of the large cylinders is transmitted by connecting
rods from their plungers to a crank shaft provided with a flywheel or pulley L, by
which the dynamo C is driven as above described, the accumulators being charged
from it, and the electricity from them in turn serving to actuate the electro-motors
on the driving axle of the locomotive. Starting and reversing devices, or switches,
of any of the well-known kinds, are used, at E or other convenient position.
In order to operate the apparatus described, the accumulators are first charged
from any suitable source. When once charged they are used to drive the electro-
motor which itself drives the smaller set of pumps which transmit their motion by
the pressure of the water to the larger set of hydraulic cylinders, which in turn
operate a dynamo the electricity from which drives the electro-motors upon the
axle of the locomotive and also serves to re-charge the accumulators as they
become discharged.
A whistle may be arranged, operated from the compressed air reservoir by which
the brakes are worked.
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 :-
1. An electric locomotive, having conical ends, and characterized by the com-
bination of an electro-hydraulic motor, accumulator, and dynamo restoring, when
at work, and in proportion as it is used, the electricity which had been stored in
the accumulator before starting, substantially as described and illustrated.
2. In combination with the parts described and operating as claimed in Claim 1,
incandescent electric lamps and other parts, that is to say, whistle, starting and
reversing gear, air brake, and screw fans, substantially as described and illustrated.
