I, The Honorable CEOIL DUNCOMBE, of Nawton Grange, Nawton, in
the County of York, do hereby declare the nature of the said In-
vention for "AN IMPROVED SPRAY GENERATOR AND INJECTOR," to be as
follows:-
-
The object of my Invention is to mix any liquid in the form of spray
or otherwise with atmospheric air, gases, steam, or vapour, forced or
passed through a pipe or other appropriate vessel by blowing engines or
any other means,. and to inject the air, gas, or vapour, and liquids when
mixed, into any receiver or convertor containing metals in a molten state,.
or other liquids to be thus purified, or for the conversion of iron into
steel or metal having the properties of steel, for disinfecting and fumi-
gating buildings, rooms, ships, and other places, or for any purpose
for which such an apparatus, as is hereafter described, may be required.
The apparatus by which I propose to effect the mixing of the air,
gases, or vapours with the liquids, and their injection into the receiver

page_text: or convertor, may be described as follows:-I place a pipe or other
suitable vessel through which the air, vapour, or gases are forced or
passed, and above this pipe I place one or more receivers to contain the
liquids to be mixed with the air, gases, or vapours, and injected into the
receiver or convertor. The receiver is connected with the air pipe by
means of a pipe leading from the bottom thereof supplied with stop-
cock or valve. The liquids pass out at the bottom of the receiver
through this pipe regulated in supply by the stop-cock or valve into the
air pipe above mentioned. I fix a pipe leading from the air pipe to the
top of the receiver or receivers, entering the receivers above the level of
the liquids, in such a manner that whatever pressure may be exerted by
the compressed air in the lower pipe will be exerted in the upper one,
and also on the surface of the liquids in the receiver or receivers. By
gravitation the liquids will be carried through the stop-cocks or valves.
into the air pipe when the current of air, gas, or vapour, impinging
upon them will break them up into spray, mix with them, and carry
them into any vessel or elsewhere, for any of the purposes above stated
that may be required.
At the top of the receiver or receivers may be placed gauges fitted
with stop-cocks at top and bottom to measure the quantity of liquid
introduced into the receivers, and so that the liquid may be supplied to
the receivers while the apparatus is in operation, and without the escape
of any air, gas, or vapour.
To the pipe or pipes at the bottom of the receiver to contain the
liquids, and leading from the receiver to the air pipe, a rose may, if
necessary, be attached, so that the fluids may be minutely divided before
the stream of air, gas, or vapour impinges upon them.
If more receivers than one are used to contain liquids to be admitted
into the air pipe, the pipes conveying the liquids from them may be
connected together, so that the different liquids may enter the air pipe
together, or be cut off by one valve or stop-cock.
