I, FREDERICK WILLIAM BOND of 5 High Street, Lambeth in the County of Surrey,
Engineer, do hereby declare the nature of this invention, to be as follows
My improvement consists first in the use of two pipes, chambers or receptacles
placed one inside the other, the inner one connected at top to a steam pipe for steam
to pass through the outer and covering pipe forming an air space or chamber which is
connected at top above the water or liquor level to the steam pipe by means of a cap
or collar keeping the respective pipes proper distance apart, allowing however the
admission of air to the pipe to be regulated. The steam pipe terminates in a
nozzle in a chamber forming a continuation of the air pipe, which chamber has an
inlet or inlets behind the nozzle to admit water or liquor to allow of its mixing in the
chamber with the steam, and another inlet or inlets in the centre or nearly so of said
chamber to allow more water or liquor to enter and be mixed with the steam. The
said liquor and partly condensed steam is then forced out of the other end of the
chamber (which may be made of almost any shape or form) and causes the water or
liquor that is to be heated to circulate and to pass through the mixing chamber over
and over again, thereby heating the water or liquor all over the boiler, tank, or
whatever vessel that contains the water or liquor.
The object of an air chamber is to stop the noise of the mixing of steam and water
by allowing of a partial vacuum in the air chamber to serve when water is cold for
giving back pressure to the steam.
I can arrange the apparatus with an inlet for water or liquor and a tube or tubes
for steam and one or more tubes for air and connect all these pipes with a mixing
chamber-also 1 can render adjustable the passage of air to or from the air chamber.

page_text: I, FREDERICK WILLIAM BOND, of 5 High Street, Lambeth, in the County of
Surrey, Engineer, do hereby declare the nature of my invention, and in what manner
the same is to be performed, to be particularly described and ascertained in and by
the following statement :-
This invention relates to the boiling or heating of water or other liquid by the
injection of steam or heated vapour therein, and it consists of an improved apparatus
for this purpose.
The apparatus consists of two pipes chambers or receptacles, placed one within the
other, the inner pipe, chamber, or receptacle being connected above to a steam inlet
pipe and ending below in a nozzle or outlet for said steam-The outer pipe chamber
or receptacle, passes upward above the level of the water or liquid and is provided
with adjustable air inlets-it terminates below in a mixing chamber about the steam
nozzle aforesaid, said mixing chamber having inlets for water or liquid to be heated
or boiled, behind the nozzle and in front thereof, and an outlet or outlets in front of
said nozzle.
Referring to the accompanying drawings illustrating two forms of improved boiling
or heating apparatus.
A is the steam chamber, pipe, or receptacles connected at a with the steam supply
pipe, and having below the nozzle b. B is the air chamber about said steam chamber,
said air chamber having the upward extensions C, which may or may not surround
the steam chamber-Said extension passes upward above the level of liquid in the
receptacle, and has at its upper end an indented edge over which the cap D may be
screwed so as to cover more or less of such indent or indents and thus decrease or
enlarge the air inlet formed by said indent or indents. If the extension C surrounds
the chamber A and said chamber and extension are tubular, then the cap D may be
arranged as a collar about the pipe A. If the extension C does not surround said
chamber A, then the outer face of the upper end of the extension A (this end being
then made tubular) is screw threaded, and the cap is arranged to screw down thereover.
E is the mixing chamber, F being inlets for the liquid behind the nozzle. G being
inlets for liquid before the nozzle, said inlets being so arranged as to guide the current
or currents of liquid entering thereby into the chamber in a direction not opposed to
that of the steam issuing from the nozzle b. The front end H of the mixing chamber
may be entirely open as in Figs. 3 and 4 or provided with outlets as in Figs. 1
and 2.
Since it is found to be advantageous for the noiseless working of this apparatus,
that the air chamber should be also in special connection with that part of the mixing
chamber which lies in front of the nozzle b-The pipe or tube K Fig. 1 and 3 is
arranged so as to connect the portion of the mixing chamber in front of the nozzle b
with that in rear of the same.

page_text: This apparatus fixed in a tank, boiler, vat or the like in which the liquid is to be
heated, the action of the steam causing a circulation through the mixing chamber.
To enable the apparatus to be fixed in such tank or the like as may be of suitable
material to enable such fixing to be performed, the wall of the mixing chamber carries
a flange or foot L bored for the passage of a screw or screws by which the apparatus
may be fixed to the floor of such tank.
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 :-
1. The combination with a mixing chamber of a steam pipe or chamber having a
nozzle projecting into said mixing chamber and an air chamber surrounding said
steam chamber and communicating with the mixing chamber behind said nozzle.
2. The combination with a mixing chamber of a steam pipe or chamber having a
nozzle projecting into said chamber and an air chamber surrounding said steam
chamber and communicating with the mixing chamber behind said nozzle, said
mixing chamber having inlets for liquid behind said nozzle and inlets for liquid before
said nozzle, said inlets not opposed in direction to said nozzle, and an outlet or outlets
before said nozzle.
3. The combination with a mixing chamber, of a steam pipe or chamber having a
nozzle projecting into said chamber and an air chamber surrounding said steam
chamber, and communicating with said mixing chamber behind said nozzle and also
before said nozzle.
4. The combination with a mixing chamber of a steam pipe or chamber having a
nozzle projecting into said chamber, and an air chamber surrounding said steam
chamber, said air chamber having adjustable communication with the atmosphere.
