Cycles and Engines generally.
I, LEWIS CLEMENT, of 131, Jermyn Street, Regent Street, London, Engineer,
do hereby declare the nature of this invention to be as follows:-
The object of this invention is to provide a new method for obtaining motive
power for motor cars, motor cycles and other engines.
Now, according to this invention, I provide large, stout steel cylinders which
can be opened and each of which contains a small receptacle wherein is placed
à solution of sulphuric acid. At the bottom of the cylinders I place a number of
crushed pieces of marble, or similar material. When the steel cylinders are
closed, the solution is upset on the marble pieces whereby an enormous quantity
of carbonic acid gas, in solid, liquid and gaseous form, is generated and this
gas, when released, constitutes my motive power. Moreover, this motive power
can be used, not only to drive the motor car, motor cycle, or other engine, but
also to drive a compressing pump, which, with suitable appliances, will liquefy,
or compress the air of the atmosphere, in suitable receptacles from whence it can
be used as an auxiliary motive power.

I, LEWIS CLEMENT, of 52, Maida Vale, in the County of London, late of 131,
Jermyn Street, London, 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:-
The object of this invention. is to provide a new method for obtaining motive
power for propelling motor cars motor cycles and for driving engines or motors.
As is well known oil engines gas engines and steam engines are unsatisfactory
for propelling motor cars and motor cycles inasmuch as the former are non-
reversible and run at a constant speed the oil used and the products of combustion
are objectionable also on account of smell, gas engines also run at a constant
speed and cannot be reversed and a large quantity of compressed gas must be
carried in cylinders.
Steam engines although reversible and easily handled require a boiler which is
ר

page_text: apt to produce smoke and requires constant attention the exhaust steam also is
not easily condensed and silenced without the aid of condensing water and an
air pump.
Now according to this invention I propel motor cars motors cycles and generally
actuate engines or motors by means of carbon dioxide which gas is odourless does
not require condensing and may be used instead of steam to drive any ordinary
steam engine.
The carbon dioxide is generated as needed, no cylinders of compressed gas
being required and the materials from which it is obtained are easily procured.
In carrying my invention into practice I provide two or more cylindrical
receptacles or generators preferably of steel which are charged with water and
whitening marble chippings or chalk in suitable "proportions and inside each of
the said generators is a bottle or other suitable receptacle, containing hydro-
chloric acid or sulphuric acid strong' or 'dilute
A pipe leads from the top or thereabouts of the generator to the valve chest
of the motor.
The acid bottle is supported on trunnions so that when desired to use a certain
generator the acid bottle is turned upside down and the acid mixed with the water
in the generator and carbon dioxide under pressure evolved which is conveyed
to the valve chest of the motor through the aforesaid pipe.
And in order that my said invention may be fully understood I will proceed
to explain the same. with reference to the accompanying sheet of drawings in
which
Fig. 1 represents elevation of a generator constructed according to this in-
vention.

The same letters denote the same parts in all the figs.
a is a cylinder of steel or other suitable material lined with lead or other acid
proof material and having a hemispherical bottom and fitted with a gas tight
cover b secured thereto by bolts c or by any other suitable means.
The said cover is provided with a safety valve d and pressure gauge f.
9. is a pipe to convey the gas to the motor h is a bottle of lead or other suitable
acid proof material suspended on trunnions j j¹ one of which ¹ terminates in
a handle by means of which the bottle may be turned bottom upwards. The
bottle may be provided with a loosely fitting lead stopper to prevent the acid
from splashing over from the motion of the car or other vehicle.
For convenience in manufacture the bottle h is held in a ring / having
bosses m m diametrically opposite to one another into which are screwed the
trunnions j j¹.
The trunnion j rotates in a bearing formed in a boss m¹ formed on the
cylinder a closed by a gastight cap n while the trunnion j passes through a
gland o and stuffing box p on the opposite side of the cylinder.
9 is a lead funnel fitting into a socket r at the top of the lead pipes which
is fixed to the side of the cylinder a to conduct the acid from the bottle h
underneath the chalk whitening or marble t is a pipe to enable the spent chalk
whitening or marble & water to be blown out of the generator.
While one generator is in use the other may be blown out and recharged
ready to be put into action as soon, as, the gas in the other generator is
exhausted.
It is preferable when applying my invention to motor cars motor cycles boats
and other vehicles to commence the journey with both generators charged.
To generate gas the requisite quantities of carbonate of lime in the form of
marble chippings whitening or chalk and water are placed in the generator the
acid bottle filled and the cover of the generator secured thereto the acid bottle
is turned upside down allowing the acid to run down to the bottom of the
generator.

page_text: 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:-
1. Obtaining motive power for propelling vehicles and other purposes by
generating carbonic acid gas in closed vessels from a mixture of acid water and
carbonate of lime the acid being contained in a bottle or other suitable receptacle
suspended inside the said vessel and capable of being turned bottom upwards when
the gas is required all substantially as specified.
2. A generator for obtaining carbonic acid gas for use as motive power con-
sisting of a cylinder of metal or other suitable material having an acid proof
lining and a gas tight cover an acid bottle or other receptacle for acid supported
on trunnions at or near the top of the cylinder a handle for rotating the said
said trunnions and a funnel and pipe to convey the acid from the bottle to the
bottom of the cylinder all substantially as specified..
