Hydrocarbon Oils.
We, GEORGE LEONARD MORRIS, and WILLIAM THOMAS WILSON both of 43 Great
Ormond Street, London, W.C. Engineers, 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 apparatus according to our invention is devised as a cheap economical and
efficacious means for the generation and utilisation of gas from hydrocarbon oils, and
may be employed with advantage for the following amongst other applications, that
is to say, in connection with a blow pipe; as also, for heating and lighting, and motor
and other purposes.
In the accompanying drawings we have illustrated in sheet 1. the apparatus when
used in conjunction with a blow pipe (such as is used for various metallurgical
operations) for which it is especially adapted; in reference to which application A
is the improved gas generating apparatus according to my invention, within which is
arranged a spiral wall a forming with the top and bottom, a continuous coil. The
lower part of the wall a is not secured to the bottom of the enclosing case or
chamber A but rests upon a layer B of fibrous, spongy or other absorbent material or
substance; the convolutions of the continuous coil are also fitted with an absorbent
material for holding in suspension the hydrocarbon oil from which gas is to be
obtained. In the centre of the enclosing case or chamber A is inserted a bent tube D
perforated at the back thereof,-for the purpose to be hereinafter described-and
terminating in a nozzle. Said bent tube D, which serves as a delivery or blast pipe,
connected with the inner end of the continuous coil a above described. A second
tube or pipe E to serve as a supply pipe for the injection of air under pressure into
the continuous coil, is secured to the outer enclosing case or chamber A in direct
connection with the outer end of said continuous coil a. A short tapered tube F,
which forms a junction with the tube E at c, passes through the perforation 6 aforesaid
in the back of the tube D to which it is attached, extending centrally to the end, or
nearly so, of the nozzle of said tube D. In using the apparatus the chamber is

page_text: charged with oil through the cap c, and air is forced into the tube E, a portion of
which, passing through the tapered tube F tends to create a partial vacuum at the
outlet of the nozzle d of the delivery or blast pipe D, drawing gas from the enclosed
continuous coil a. A larger proportion of atmospheric air relatively to that passing
down the tapered tube F is forced down the tube E' into and through the absorbent
material in the continuous coil a aforesaid, becoming in its outward passage to the
pipe D and nozzle d highly charged with olefiant gas, which, upon ignition at the
nozzle, burns with intense heat.
Instead however of employing a continuous coil for the generator as shown in
sheet 1, we may use the arrangement illustrated in the diagram sheet 2; under
which arrangement, the generator comprises a series of vertical walls or baffle plates,
the intersticial spaces between which, are filled, as in the device shown in sheet 1,
with a suitable absorbent material. The air in this alternative arrangement entering
at G travels in the direction shown by the arrows, and makes its exit at H highly
charged with the gas taken up in its passage.
If desired, the gas generated in the apparatus above described, may be stored in
suitable reservoirs, and utilised for illuminating and heating purposes, or it may be
employed for the latter purposes direct from the generator.
Said gas may also be used with advantage in the working of gas Engines
and the like, taking it either from the reservoirs in which the gas is contained, or
direct from the generator as above described for illuminating purposes.
Having now particularly described and ascertained the nature of our said inven-
tion and in what manner the same is to be performed, we declare that what we
claim is..
..
The improved apparatus for the generating of gas from hydrocarbon oils substantially
as herein described and shown in the accompanying drawings.
