Purposes by the Combustion of a Combination of Gas and Air.
We WILLIAM EVANS, 1 Joseph Street, Shawclough, Rochdale Manager and
GEORGE HALL 274 Bolton Road Irlams-o th Height Manchester, Clerk, both in the
County of Lancaster, 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 :—
Our Invention relates to an apparatus for utilizing atmospheric air in combination
with gas, for the rapid and more intense generation of heat, for heating water in
steam boilers and thus quickly producing steam, and for heating metallic plates or
rollers for drying purposes, and for any other purpose for which heat is ncesesary,
and which can be produced by means of the combustion of the aforesaid combination
in connection with the said apparatus hereinafter described, as consisting of a forked
tube or pipe B with two prongs at one end, and connected at the singlo end with a fan
or ventilator A and another forked tube or pipe D with three prongs at one end, the
two outside prongs of which are joined to the two prongs of the first named tube or
pipe B by means of india rubber or any other kind of tubing C. The middle prong E
of the second named or three pronged tube or pipe D is connected with a tubo or pipe
conveying the gas, the single end F of the second named or three pronged tube or
pipe D is perforated with a number of holes on the upper side or all round it as
may be required, and in these holes burners are fixed or not, as may be desired.
The prongs of the two before mentioned tubes or pipes are hollow, so that the
tubes or pipes are at the one end two way and three way tubes or pipes respectively;
the two way tube or pipe B being at the single end open, and in connection with the
said fan or ventilator A the single end of the three way tube or pipe F being open
or closed as may be required, but throughout its length being perforated with
numerous holes. When the said fan or ventilator A is set to work, the gas is
mingled or mixed with the air coming through the outside prongs; and this
combination of gas and air being lit at the said perforations or burners, and blown
by means of the said fan or ventilator A gives off intensely hot flames, which may be
regulated by taps H and J connected with the said gas tube or pipe E and fan or

page_text: ventilator A respectively; the effect being that by the combustion of the said
combination of air and gas in the manner hereinbefore described, a manifold more
intense heat is produced than could have been produced from the single jet of flame
represented by the amount of gas used and acting in the ordinary way without the said
apparatus.
We would observe that we do not confine ourselves to the particular arrangement
of the pipes as before described, as they may be otherwise combined with the said fan
or ventilator to render them suitable for the production of the said combination of air
and gas or gases of an inflamable nature of any kind whatsoever.
Moreover, the single way parts of the said tubes or pipes may be either straight or
curved, or a combination of both as may be most suitable for the circumstances under
which they are required, and of any length deemed desirable.
Further, more than one set of tubes or pipes, and fan or ventilator may be used
either singly or in conjunction, to effect the purposes herein-before indicated, or
others for which they may bo found suitable.
And in order that our invention may be better understood, we have appended hereto
one sheet of drawings lettered according to the references contained in the foregoing
specification.
Figures 1 and 3 are elevations representing two forms which may be adopted, and
Figure 2 is a plan partly in section-applicable to both of the said elevations.
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.-
1st. The arrangement and construction of the pipes or tubes, and their connection
with a fan or ventilator in the manner herein-before described, or in some other
manner which, though differing in arrangement shall in the result be substantially the
same.
2nd. The combustion in the inanner herein-before described of the combination of
air and inflamable gas or gases of whatsoever kind, to produce the results herein before
indicated, and any others analogous thereto.
In witness whereof we the said William Evans and George Hall have hereunto
set our hands and seals this Third day of March in the year One thousand
eight hundred and eighty eight.
WILLIAM EVANS.
