both of Leeds, in the County of York, for an Invention of "IMPROVEMENTS
IN THE MEANS OR APPARATUS EMPLOYED FOR HEATING WATER AND OTHER
FLUIDS, PART OF
SUCH IMPROVEMENTS BEING APPLICABLE FOR OTHER
PARDOSES "
PROVISIONAL SPECIFICATION left by the said George Henry Nussey and
William Bradshaw Leachman at the Office of the Commissioners of Patents
on the 20th January 1882.
GEORGE HENRY NUSSEY and WILLIAM BRADSHAW LEACHMAN both of, Leeds
in the County of York. "IMPROVEMENTS IN THE MEANS OR APPARATUS
EMPLOYED FOR HEATING WATER AND OTHER FLUIDS, PART OF SUCH IMPROVE-
MENTS BEING APPLICABLE FOR OTHER PURPOSES."
Our improvements are applicable for heating or boiling the water or other liquids
in dye pans or in other vessels, tanks or receivers and for this purpose we inject
therein a combination of hot air and superheated steam and in order to effect this
end we provide an injector which may be similar in construction to those in use
for forcing water into boilers. The steam being applied and passing through it
draws with it hot air which in combination are directed into the pan, tank or
receiver.
The hot air having the effect of superheating the steam both pass into the liquid
at a very high temperature the effect of this being that the liquid is much more
quickly heated, requiring less steam than when that alone is employed. We obtain
hot air either from a hot air chamber or other convenient source, the steam is
obtained from an ordinary boiler.
For the purpose of procuring a large supply of hot air we provide an apparatus
for drawing and supplying it to the injector and for this purpose we provide two
drums or bosses mounted on a shaft in suitable bearings. On the periphery of
these drums are provided vanes of a screw propeller form, one being a right and
the other a left hand screw, these when caused to rotate draw air into the case in
which they are enclosed and force it into the hot air chamber and thence to the
injector which is connected with the air chamber by suitable tubes or pipes.
This arrangement of apparatus is also applicable for drawing and forcing air or
water for other purposes.

DESCRIPTION OF DRAWINGS.
Fig. 1 is a transverse section and Fig. 2 a plan looking at the top of one arrange-
ment shewing application of our Invention for heating or boiling. water or other
liquids in dye pans or other vessels. Fig. 3 is a transverse section and Fig. 4 a
plan shewing further arrangement and application of our Invention. Fig. 5 is a
transverse section and Fig. 6 a part front and part sectional elevation of our
invention for drawing and supplying air for the injector. Fig. 7 is a transverse
section and Fig. 8 a front elevation shewing a modification in the same which is
also applicable for drawing and forcing water and for other purposes. Fig. 9 is a
transverse section of a further application of our Invention.
At Figs 1 and 2 a represents a vertical boiler of ordinary construction and ba
tank or other vessel containing the water or other liquid to be heated. This tank b
may be either open or closed at the top in which latter case the steam coming off
from the tank may be used for other purposes. In order to heat the water in the
tank b we inject a combination of hot air and superheated steam and for this
purpose we employ an injector c which consists of the barrel or box d in which is
provided the taper tube or nozzle e of a similar construction to those used for

page_text: injecting water into steam boilers. We connect the vertical boiler a with the
injector c by means of the steam pipe f provided with a regulator or cock g. From
the flue or chimney h we provide a passage i connecting it with the barrel or:
box d of the injector c; we also connect the barrel or box d with the tank 6 by
means of a pipe k.
.
On steam being generated in the boiler to a sufficient pressure the regulator or
cock g may be turned on when the steam will rush through the nozzle e down the
pipe and force its way into the tank b drawing with it the heated gases and air
from the boiler furnace a¹ The hot air having the effect of superheating the steam
both pass into the liquid at a very high temperature.
The
Instead of taking the hot air from the furnace a¹ as shewn the air passage i
may be connected with a hot air chamber or other convenient source.
damper is employed for closing the chimney at the top when the hot air and gases
from the furnace a¹ are required to pass through the injector c.
When preferred the steam and hot air may be admitted into a float m through
the swivelling steam and air pipe n as shewn at Figs 3 and 4 and so heat the water
from the top instead of as shewn at Figs 1 and 2.
For the purpose of securing a large supply of hot air we provide the apparatus
shewn at Figs 5 and 6 which consists of the bosses o mounted on a shaft p carried
in bearings q on the shell or casing r. On the periphery of the bosses o are
provided vanes 8 of a screw propellor form one having a right and the other a left
hand screw.
These when caused to rotate through the medium of the driving
pulley t draw air into the casing or shell r and force it into any convenient hot air
chamber and thence to the injector c, through opening ¹. A modification of this
arrangement is shewn at Figs 7 and which is of a similar construction except
that it is provided with side flues or passages u. This arrangement is not
only applicable for drawing or forcing air but also water or other liquids for
other purposes. Corresponding parts in Figs 5 and 6 and 7 and 8 are marked with
like letters.
At Fig 9 is shewn a further application of our improvements. v is a tank
containing a number of drawers or flanged shelves w. The supply of water or
other liquid to be heated is admitted at x this fills the uppermost drawer or shelf
and by continuing the supply of water or liquid thereto it overflows and trickles
down into the next drawer or shelf below and so on until the whole of the drawers
or shelves w are filled. The water or other liquid also overflows, the bottom drawer
and passes off through some suitable outlet.
Whilst the water is overflowing the various drawers or shelves w we inject hot
air and steam into the tank v by any of the means herein set-forth and whilst the
water is trickling over the end of each drawer it has to pass in drops through the
intensely heated atmosphere. By this means its temperature is increased to any
required extent. The hot air and steam can be passed into the tank v either at y
or at z.
Having now described the nature of our said Invention and described with the
aid of drawings how the same may be carried into practice we would have it
understood that we do not limit ourselves to the precise details or configuration
of the parts we have described and shewn as the same may be varied or modified
without departing from the nature of our said Invention, but what we do claim is :—
Firstly. The general arrangement and combination of the various means
employed for heating water and other liquids substantially as and for the purposes
herein set-forth.
Secondly. The arrangement, construction, and application of the injector c in
combination with apparatus for the supply of hot air for the purpose of drawing
and forcing the same into dye pans, tanks, or receivers substantially as and for the
purposes herein set-forth.
Thirdly. The arrangement, construction, and application of the means or
"

page_text: apparatus for drawing and supplying hot air to the injector c also for drawing
and forcing air or water for other purposes substantially as shewn at Figs 5, 6, 7
and 8.
In witness whereof I the said William Bradshaw Leachman for myself and
on behalf of George Henry Nussey have hereunto set my hand and seal this
thirteenth day of July in the year of Our Lord One thousand eight hundred
and eighty two.
