PROVISIONAL SPECIFICATION.
Improvements in or connected with Air Injectors.
I, WILLIAM HICHENS RICKARD, of Isca Hotel, Clarence Place, Newport, in
the County of Monmouth, South Wales, Mechanic, do hereby declare the nature
of this invention to be as follows:-
:-
The object of my invention is to obtain better means than heretofore for inducing
or producing air blasts in furnaces and for other purposes, and by means of my
invention a pure air blast is obtained without the admixture of steam as is now the
case in blast apparatus at present in use.
According to my invention I so arrange the blast injector that the steam, after
drawing in the air, is met by a jet or jets of water, or the water may be admitted
and travel in the same direction. The jet or jets, in spray, or in any other form, of
water condenses or condense the steam, which at once falls, separating as it does so,
from the air, which latter passes on to feed the furnace or for any other purpose
for which it may be required. The condensed steam is caught as it falls in a tank
or other suitable receptacle and is then conducted to the exhaust.
The pressure of the blast is so arranged as to regulate the tank or other
receptacle.

COMPLETE SPECIFICATION.
Improvements in or connected with Air Injectors.
I, WILLIAM HICHENS RIOKARD, of Isca Hotel, Clarence Place, Newport, in
the County of Monmouth, South Wales, Mechanic, 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 object of my invention is to provide better means than heretofore for inducing
or producing air blasts for furnaces or for other purposes, and whereby a pure air
blast is obtained without the admixture of steam as is now the case in blast
apparatus.
According to my invention I so arrange the blast injector that the steam, after
drawing in the air, is met by a jet or jets of water, or the water may be admitted
and travel in the same direction.. The jet or jets, in spray or in any other form, of
water, condenses or condense the steam, which at once falls, separating as it does
so from the air, which latter passes on to feed the furnace or for any other purpose
for which it may be required. The condensed steam is caught as it falls in a tank
or other suitable receptacle and is then conducted to the exhaust.
In order that my invention may be more readily understood, I have appended a
diagram shewing as an example, one way in which my invention may be carried
into effect.
On the aforesaid diagram A is a steam jet drawing air into the injector device B ;
C is a water inlet. At any convenient distance from the point C where the water
is admitted (for the purpose of condensing the steam) a box or casing D or other
suitable device may be provided formed with or having division plates D¹ to admit
of the water being conducted to a lower conduit while the air blast passes by the
passage E to be delivered where required.

page_text: I do not limit myself to the precise means for separating the air blast from the
condensed steam and water, as other arrangements may be employed, such as
would readily be applied by persons acquainted with the subject, such for example
as providing pipes for carrying away the condensed steam and water.
It will also
be understood that the air and water may be admitted at more than one place.
Having now particularly described and ascertained the nature of my said inven-
tion, and in what manner the same is to be performed, I declare that what I
claim is :-
1. In air injectors, the introduction therein of a spray or sprays, jet or jets of
water, whereby the steam is condensed, the condensed steam and water being
separated from the air and the said air being delivered, unmixed with steam, to be
employed for the required purpose or purposes substantially as set forth.
2. In air injectors, the combination, with a stean jet or jets A and an air injector
tube B, of water inlet or inlets C, separating device D and air delivery E, all
constructed and acting substantially as and for the purposes herein described.
