CERTAIN IMPROVEMENTS IN HEATING WATER, GENERATING STEAM, AND SAVING FUEL
Year: 1846

page_text: TO ALL TO WHOM THESE PRESENTS SHALL COME, I, GEORGE
LODGE, of Leeds, in the County of York, Engineer, send greeting.
WHEREAS Her present most Excellent Majesty Queen Victoria, by Her
Royal Letters Patent, under the Great Seal of Great Britain, bearing date at
Westminster, the Tenth day of August, in the tenth year of Her reign, did;
for Herself, Her heirs and successors, give and grant unto me, the said George
Lodge, Her especial licence, full power, sole privilege, and authority, that I, the
said George Lodge, my executors, administrators, or assigns, and such others as
I, the said George Lodge, my executors, administrators, or assigns, should at
any time agree with, and no others, from time to time and at all times during
the term of years therein mentioned, should and lawfully might make, use,
exercise, and vend, within England, Wales, and the Town of Berwick upon
Tweed, my Juvention of "CERTAIN IMPROVEMENTS IN HEATING WATER, GENERATING
STEAM, AND SAVING FUEL;" in which said Letters Patent is contained a pro-
viso obliging me, the said George Lodge, by an instrument in writing under
my hand and seal, particularly to describe and ascertain the nature of my said
Invention, and in what manner the same is to be performed, and to cause the
same to be inrolled in Her Majesty's High Court of Chancery within six
calendar months next and immediately after the date of the said in part recited
Letters Patent, as in and by the same, reference being thereunto had,' will
more fully and at large appear.

page_text: NOW KNOW YE, that in compliance with the said proviso, I, the said
George Lodge, do hereby declare that the nature of my said Invention, and
the manner in which the same is to be performed, is particularly described
and ascertained in and by the following description thereof, reference being
had to the Drawings hereunto annexed, and to the letters and figures marked
thereon (that is to say):-
°
This Invention consists in an improved arrangement of apparatus whereby
the heating of water may be economically effected (an increased heating surface
being exposed to the action of the flame and heated gases), and a large supply
of steam may be quickly generated. The apparatus which I employ for this
purpose is shewn in the accompanying Drawing as applied to a furnace in
conjunction with an ordinary waggon-shaped boiler. It consists of two rect-
angular vessels or chambers of iron set parallel to each other, one on either
side of the fire-place, and connected together in front by a hollow arch, made
also of iron. These vessels or chambers are intended to receive the water
from the force pump, and by means of pipes with which they are provided
conduct the water over a considerable heating surface before it enters the
waggon-shaped boiler: Figure 1 is a sectional elevation of a furnace fitted
according to my Invention, the front end plates of the chambers before
mentioned being removed. Figure 2 is a view shewing the boiler and my
improved steam generating apparatus in plan detached from the furnace; and
Figure 3 is a sectional plan of the improved generating apparatus taken in the
line 1, 2, of Figure 1. A, A', are the two rectangular chambers through which
the water passes in its way to the boiler. It is obvious that these chambers
may be of a cylindrical or other required form; but the construction shewn
in the Drawing I prefer, as an extensive heating surface is thereby presented
to the fire. B is the hollow arch connecting the two chambers together, and
forming a passage for the water from one chamber to the other. C is the
boiler resting on the chambers A, A¹, and connected to the chamber A by a
pipe D. E is a pipe leading from the supply pump to the chamber A', and
F is a pipe within the chamber A', and forming a continuation to the pipe E, for
the purpose of conducting the water as it is supplied by the force pump to the
opposite end of the chamber at which it enters, as shown by the arrows in
Figure 3. The other chamber A is similarly provided with a pipe G, forming a
continuation of the pipe D, and having an open end near the back end of that
chamber. By this arrangement it will be understood that the water as it
enters at the pipe E will flow along the pipe F to the back end of the
chamber A'; it will then return to the front, and by the continued action of
the pump be made to rise up the hollow arch B, and pass into the chamber A.

page_text: When it has traversed the length of that chamber it will enter the pipe G,
and passing forward it will rise up the pipe D, and flow into the boiler in a
heated state. On referring to the elevation, Figure 1, it will be seen that the
boiler is fixed so that the play of the flame around it will be precisely the
same as in the ordinary mode of setting such boilers; the heat is therefore as
economically employed with regard to its action on the water in the boiler as
heretofore. The chambers A, A', (which occupy the place hitherto filled with
solid brickwork for supporting the boiler,) will therefore, in exposing the water
while passing to the boiler to the action of the fire, cause it to take up a con-
siderable portion of heat that might otherwise be lost, and as the water is thus
submitted to the fire in a comparatively small body, it will become quickly
heated, and entering the boiler in that state will speedily be converted into
steam.
Having now described my Invention, and the manner of carrying the same
into effect, I wish it to be understood that under the above in part recited
Letters Patent, I claim the improved arrangement above described for raising
the temperature of water on its passage to the boiler, whereby steam may be
more quickly generated than by conveying the water directly from the well or
supply cistern to the boiler, and also an economy of fuel will result.
In witness whereof, I, the sail George Lodge, have hereunto set my
hand and seal, this Ninth day of February, in the year of our Lord
One thousand eight hundred and forty-seven.
AND BE IT REMEMBERED, that on the same Ninth day of February,
5 in the year above mentioned, the aforesaid George Lodge came before our
Lady the Queen in Her Chancery, and acknowledged the Specification afore-
said, and all and everything therein contained, in form above written. And
also the Specification aforesaid was stamped according to the Statute of the
Statute in that case made and provided.
