PROVISIONAL SPECIFICATION.
A Method of and Apparatus for Generating Elastic Fluid for
Working Engines.
I, EDWARD EUGENE DULIER of No. 27 Sloane Gardens, Chelsea, in the
County of London, Retired Military Officer, do hereby declare the nature of this
invention to be as follows :—
My invention relates to the generation of elastic fluid for working engines, which
I effect in the following manner. By means of a compressor worked by the engine
1 force air through a coke fire contained in a strong closed vessel, lined with
refractory material. I cause the hot products of combustion, preferably after
filtering them through asbestos, to pass along a pipe or channel into which water
is injected in finely subdivided spray. The steam generated in the pipe, mixed
with the products of combustion, is led to the engine to operate as working fluid.
The injection of the air into the fire and of the water into the pipe may be
continuous or may take place at each stroke of the engine. At first starting, or,
if desired, during continuous working, the fire may be supplied from a store of
compressed or liquid air or oxygen.

A Method of and Apparatus for Generating Elastic Fluid for
Working Engines.
I, EDWARD EUGENE DULIER, of No. 27 Sloane Gardens, Chelsea, in the
County of London, Retired Military Officer, 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 relates to the generation of elastic fluid for working engines, which
I effect in the following manner. By means of a compressor worked by the engine
I force air through a coke fire contained in a strong closed vessel, lined with
refractory material.
I cause the hot products of combustion, preferably after filtering them through
asbestos, to pass along a pipe or chaunel into which water is injected in finely
subdivided spray.
The steam generated in the pipe, mixed with the products of combustion, is led
to the engine to operate as working fluid. The injection of the air into the fire
and of the water into the pipe may be continuous or may take place at each stroke
of the engine.
At first starting, or if desired, during continuous working, the fire may be
supplied from a store of compressed or liquid air or oxygen.

page_text: The accompanying drawing is a section shewing, by way of example, one form
of apparatus suitable for generating elastic fluid according to the method above
described, this drawing showing how liquid fuel as well as coke can be employed.
A is a strong vessel lined with refractory material provided with a hole B for
feeding fuel, and a hole C for removing ash &c., both holes being provided with
covers to close them tightly. D is a partition extending down some distance
towards the bottom so that while there is a body of coke in the furnace it is divided
into two compartments.
E is a pipe supplying air at high pressure from a suitable compressor. This air
alone may be passed through the furnace, but, when liquid fuel is employed, it is
supplied from a closed tank F, the upper and lower parts of which communicate
with the pipe E by pipes G and H, the pipe H terminating with a suitable nozzle
from which a spray of the combustible liquid in a fine state of division is driven by
the air current operating in the manner of a scent disperser, pressure equivalent
to that in E being maintained in the tank F by the communicating pipe G. The
combustible spray and portions of the solid fuel burn with the compressed air, and
the hot products of combustion pass from the furnace, preferably through an
asbestos filter K, to a pipe L in which there is the nozzle of a pipe N communicating
with a closed water tank M in which pressure equivalent to that in L is maintained
by a pipe P. The current of hot gases causes a spray of finely divided water from
the nozzle, and this is converted into steam which mingled with the partially cooled
gases constitutes working fluid for an engine.
Having now particularly described and ascertained the nature of this inven-
tion and in what manner the same is to be performed, I declare that what I
claim is :-
1. The herein described method of generating elastic fluid for working engines
by supplying a closed furnace with compressed air, and causing the hot products of
combustion issuing from the furnace under pressure to mingle with and act on a
spray of water so as to convert it into steam which, mingled with the partly cooled
gases, constitutes elastic working fluid.
2. For operating as set forth in the preceding claim, apparatus constructed and
arranged, substantially as described.
