Improvements in Carbonic Acid Engines or Motors, and in the
Application of the same to the Driving or Propulsion of
Vehicles.
I ADOLPHE DELSEMME of No. 32 Avenue Rogier Liège in the Kingdom of
Belgium 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 :—
My invention has for its object a carbonic acid engine or motor and it consists.
in connecting the motor cylinder or cylinders to a reservoir formed of metal suitable
for containing the carbonic acid under pressure in a liquid state and into which
enters an electric conductor the ends of which are connected to the two poles of a.
dynamo or other source of electricity in such a manner that when an electric current.
passes through the conducting wire there results a heating of the carbonic acid
which in the form of gas at high tension enters the motor cylinder or cylinders for
acting upon the piston or pistons.
As this engine or motor is especially applicable to the driving or propulsion of
vehicles I have represented it in the accompanying drawings as applied to a.
tramway car.
Figure 1 is a side elevation of the car and motor partly in section.
Figure 2 is a transverse section of the same taken on the line X X Figure 1.
Figure 3 is a plan showing the underside of the car and motor.
In the said figures
A is a dynamo which when the car is in motion is driven by one of the car
wheels a from which motion is communicated to the dynamo through bevil
gearing 6b or through any other suitable medium.
B is a small battery of accumulators connected to the dynamo and which stores.
sufficient electricity to furnish the current necessary for starting the vehicle.
C is the receptacle containing the liquid carbonic acid. The said receptacle is.
surrounded with insulating material and into it enters the conducting wire K which.
conveys from the dynamo the current which heats the carbonic acid. This
receptacle C communicates with the motor cylinders J J by a pipe D furnished
with a suitable valve d conveniently connected to levers H by means of which the
driver of the car can regulate the supply of carbonic acid gas to the cylinders.
Pipes EE form communications between the receptacle C and heat and pressure
gauges G G situated near the driver for the purpose of indicating to him the degree.
of heating and pressure of the carbonic acid. Make and break devices F Farranged
in the circuit of the conducting wires K K enable the driver to control the passage.
of the current to the receiver C.
Having now particularly described and ascertained the nature of my said
invention and in what manner the same is to be performed 1 declare that I
claim :-
First. A carbonic acid engine or motor characterized by the combination of a.
receptacle containing liquid carbonic acid an electric conductor entering the said.
receptacle and connected to the two poles of a dynamo or other source of electricity
and a suitable conduit connecting the carbonic acid receptacle to the motor cylinder
for conveying thereto the gas resulting from the heating of the carbonic acid.

receptacle.
Secondly. In the application to the propulsion or driving of vehicles of a carbonic
acid engine or motor possessing the characteristics set forth in the foregoing claim
the combination with the carbonic acid receptacle and the dynamo of a battery of
accumulators connected by conducting wires to the said dynamo and to the
carbonic acid receptacle for setting the vehicle in motion and of suitable means for
driving the dynamo from one of the wheels of the vehicle when the latter is in
motion as herein before described and illustrated in the accompanying drawings.
Dated this Twenty-fifth day of January 1897.
