COMPLETE SPECIFICATION.
Apparatus for Heating by Means of Liquid Hydrocarbons.
I, SYDNEY PITT, of Sutton, in the County of Surrey, Gentleman, do hereby declare
the nature of this invention (which has been communicated to me from abroad by the
Compagnie Internationale des Procédés Adolphe Seigle, of 147 Rue de Courcelles,
Paris, France,) and in what manner the same is to be performed to be particularly
described and ascertained in and by the following statement:-
This invention has for its object an apparatus for heating by means of liquid
hydrocarbons; it consists of the following elements :-
1. A reservoir A of any shape which contains water up to a suitable level and air
compressed by means of a hand or other pump B into the portion remaining free
between the level of the water and the cover of the reservoir.
A guage C indicates the pressure in the reservoir A.
D is a filling plug.
2. A vapourizing apparatus formed of a metallic tube E coiled in a helix. The
water in the reservoir A is led into this tube by a pipe F. The steam produced passes
out at G and goes into a receiver H which forms a magazine of energy and a pressure
regulator.
This
3. A reservoir I which contains the hydrocarbons intended for heating.
reservoir which may be of any shape is placed in connection with the vapourizer.
4. A sprayer or pulverizer L of any suitable type, into which at K the hydro-
carbons from the reservoir I enter and at M the steam enters which is produced in the
helicoidal tube E.
A cock N allows the inlet of the oil into the pulverizer L to be regulated.
5. An arrangement which allows the hydrocarbons to be ignited when the apparatus
is put into action, it consists of a pipe O which takes compressed air from the
reservoir A and leads it into the receiver H.
A cock P allows communication between the reservoir A and the receiver H to be
intercepted.
This apparatus works as follows:-
The reservoir A is filled with water up to any suitable height, air is compressed
into the portion left free between the water level and the cover, by means of a hand
pump B or any other suitable mechanical means.
The reservoir I contains as has been stated the hydrocarbons to be burnt.
To set the apparatus in action the cocks M and P are opened, allowing the bydro-
carbons and the compressed air to simultaneously reach the pulverizer L.
The mixture of hydrocarbons and air passes out at R in the form of a fine dust
which may be easily ignited.
When the helicoidal tube E, the spirals of which are internally heated by the
ignited jet has attained a sufficiently elevated temperature to enable the water coming
from the reservoir A to be vaporised, the cock P is closed and the cock S opened.
Water from the reservoir A is led by the pipes F and T into the tube E where in
contact with the metal at a high temperature it vaporizes instantaneously.
The steam passes out at G into the receiver H and thence into the pulverizer at M
The cock N having been opened at a suitable moment the mixture of hydrocarbons
and steam passes out at R in the form of a fine powder analogous to that produced by

page_text: the mixture of air and hydrocarbons employed for starting the apparatus as above
de scribed.
The ignited jet at R passes into the interior, of the spirals of the helicoidal tubes
which it constantly, maintains at a sufficiently high temperature to produce the
quantity of steam necessary for the pulverizer.
+
The intensely hot flame passing out of this, helicoidal tube may then be utilized for
heating any apparatus.
The apparatus is also combined so as to be able to work with any other spraying or
pulverizing agent.
For this purpose a cock U allows to be introduced by the passage T into the
helicoidal tube any pulverizing fluid. such as air steam and the like which is not
derived from the reservoir A.
Communication with the reservoir A which in, this case no longer operates is
interrupted by closing the cocks P and S.
The details of execution may be varied as needful.
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 :-
In an apparatus for heating by means of liquid.hydrocarbons.
1. The combination consisting of a reservoir of any suitable shape containing
compressed air, of a vapourizing apparatus in which the water coming from the
reservoir is vapourized and transformed into a pulverizing fluid and of a reservoir
containing, hydrocarbons to be burned.
2. The arrangement for putting the apparatus into action consisting in the
combination therewith.. of a tube, leading compressed air from the reservoir to
pulverize the hydrocarbons, until the vapourizing tube is sufficiently heated by the
ignited jet to vaporize the water coming from the reservoir.
3. The apparatus substantially as described and shown in the annexed drawing.
