Year: 1859

page_text: LETTERS PATENT to John Smith, of Bradford, in the County of York,
Engineer, for the Invention of "IMPROVEMENTS IN APPARATUS FOR HEATING
AND COOLING WATER."
Sealed the 4th January 1860, and dated the 9th July 1859.
PROVISIONAL SPECIFICATION left by the said John Smith at the
Office of the Commissioners of Patents, with his Petition, on the
9th July 1859.
I, JOHN SMITH, of Bradford, in the County of York, Engineer, do hereby
declare the nature of the said Invention for "IMPROVEMENTS IN APPARATUS
FOR HEATING AND COOLING WATER," to be as follows:-
This Invention relates, firstly, to means of heating or boiling water for the
purpose of generating steam, or for other purposes requiring hot water, and
the improved apparatus consists of a series of pipes or tubes of cast or wrought
iron or other suitable material, constructed and arranged close side by side, in
such a manner as to form or constitute the sides of the fire-box, and of the
flues leading therefrom, in which flues are also pipes at small distances apart,
the whole of which form the water space, vessel, or boiler for containing the
water to be heated. These pipes are connected together by any suitable
means, so as to be steam-tight, and each pipe made to communicate with the
others, thus affording an extended circulation of the water. And when
adapted for generating steam, a separate vessel or receiver is employed in
connection therewith, serving as a steam chamber. The grate bars are

page_text: moveable in a lateral or sidewise direction by cog wheels applied at each end
of the said bars. The cogs being of suitable pitch and form as that each cog
will take a separate grate bar, whereby the grate bars are carried forward
continually on suitable bearings like an endless chain.
The second part of my Invention relates chiefly to means of cooling the
condensed water of steam engines; but is equally applicable to the cooling of
other hot or warm water, or liquids, and consists in the employment of a reel,
winch, or fan, which is caused to rotate rapidly upon its axes, the water being
allowed to fall thereon in a thin sheet or film, is forced or thrown off thereby
in all directions into the atmosphere in small drops like mist.
SPECIFICATION in pursuance of the conditions of the Letters Patent, filed
by the said John Smith in the Great Seal Patent Office on the 9th
January 1860.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, JOHN
SMITH, of Bradford, in the County of York, Engineer, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her Letters
Patent, bearing date the Ninth day of July, in the year of our Lord
One thousand eight hundred and fifty-nine, in the twenty-third year of Her
reign, did, for Herself, Her heirs and successors, give and grant unto me, the
said John Smith, Her special licence that I, the said John Smith, my
executors, administrators, and assigns, or such others as I, the said John
Smith, my executors, administrators, and assigns,hould at any time agree
with, and no others, from time to time and at all times thereafter during the
term therein expressed, should and lawfully might make, use, exercise, and
vend, within the United Kingdom of Great Britain and Ireland, the Channel
Islands, and Isle of Man, an Invention for "IMPROVEMENTS IN APPARATUS FOR
HEATING AND COOLING WATER," upon the condition (amongst others) that I, the
said John Smith, my executors or administrators, by an instrument in writing
under my, or their, or one of their hands and seals, should particularly describe
and ascertain the nature of the said Invention, and in what manner the same
was to be performed, and cause the same to be filed in the Great Seal
Patent Office within six calendar months next and immediately after the
date of the said Letters Patent.
NOW KNOW YE, that I, the said John Smith, do hereby declare the
nature of my said Invention, and in what manner the same is to be per-
formed, to be particularly described and ascertained in and by the following

page_text: statement, reference being bad to the accompanying Drawings, and the letters
and figures marked thereon (that is to say):-
This Invention relates, firstly, to means of heating or boiling water for the
purpose of generating steam, or for other purposes requiring hot water, and
consists of a series of pipes or tubes of cast or wrought iron, or other suitable
material, constructed and arranged in such manner as to form the sides of a
fire-box and flues leading therefrom, also having pipes at small distances apart
within the flues, the whole of which are connected together and constitute a
water space, vessel, or boiler, for containing water to be heated or boiled. The
grate bars are moveable in a lateral direction by means of cog wheels suitably
formed to take hold thereon, and by rotatory motion impel them forward.
The second part of this Invention relates chiefly to means of cooling the
condensed water of steam engines; but is also applicable to the cooling of
other hot water, or liquids, and consists in the employment of a reel, winch, or
fan, caused to rotate rapidly, the water being allowed to fall thereon in a thin
sheet or film, is thrown off forcibly in small drops or mist, the atmosphere
operating to cool it.
The Invention will be clearly understood by reference to the accompanying
two Sheets of Drawings, in which similar letters thereon refer to the same
parts of the apparatus in the different views or figures.
Figure 1 represents a longitudinal or side elevation of an apparatus for
heating or boiling water, or other liquids, or for generating steam, constructed
according to the first part of this Invention; Figure 2 is a longitudinal and
vertical section taken through the fire-box; Figure 3 is a horizontal section
of the same taken through the fire-box; and Figure 4 is a cross section, also
taken through the fire-box. The parts marked a, a, are a series of vertical
pipes or tubes, which are connected at top and bottom by horizontal pipes b, b,
and which are framed and cast, or constructed in parts or sections, as shewn
at Figures 5 and 6, and then jointed and bolted together, so as to leave a
thoroughfare or passage throughout the whole series, thus forming a con-
tinuous chamber or vessel for holding water or other liquid to be heated or
boiled. C is a pipe with branches connecting the parts or sections horizontally
at the bottom end, for supplying water thereto; and D is another pipe with
branches joining the said parts in like manner at the top end, for carrying off
the steam or hot water to any suitable receiver. The spaces betwixt some of
the pipes are filled up with a web of metal cast thereon, which form the sides
of the fire-box and flues, as will be readily seen in the plan, Figure 3. E is
the fire-box; and F, the grate bars resting upon bearings G, and on cog
wheels II, keyed on the shaft I, which wheels are geared together by other

page_text: wheels J, worms K, and shaft L, on which are the driving pullies M, by which
motion is given to the grate bars in a lateral direction, continuous like an
endless chain, the flame from the fire passing along the flues, as indicated by
the arrows; N is a hopper, with porcupine or spiked rollers, which are driven
by suitable gearing O, so as to give a regular supply of fuel to the travelling
grate bars; P is a sliding door, to enable the fire to be poked, &c.; Q is a
hinged door, with weighted lever closed to the grates, so as to prevent the inlet
of cold air; but which will open to allow clinkers, when formed, to pass or
force their way out from the fire-box. The fire-box and ashes place are
shielded on each side by metal plates R, on which are fixed the bearings for
the grate bars, and which also support the apparatus at that part, the other
parts being supported by pillars or frames, consequently no setting in brick-
work is required; S are portable slide plates to keep out cold air, and to be
removed for cleansing the flues. Figures 7 and 8 are details of the grate bars
and wheels, with a portion of the side plate and bearings supporting the said
grate bars, shewing the formation or construction thereof. Any number of
pipes may be employed, and the apparatus be made with double fire-boxes,
the flames made to join in the last flue herein shewn, or in other convenient
modes of arrangement as may be found desirable.
Figure 9 is an elevation of the apparatus for cooling water according to the
second part of my said Invention; and Figure 10 is a plan of the same.
T is a frame on which is mounted a winch or reel, with wings or beaters U;
and V is a trough to receive and conduct the hot water from the condenser of
a steam engine, or other source, from which it falls on the wings of the reel
whilst in rapid motion, which strike and throw it off high in the air, dispersing
the same in a fine spray, mist, or vapour, the atmosphere thereby operating to
cool it, when it falls into a small reservoir for further use.
In witness whereof, I, the said John Smith. have hereunto set my
hand and seal, this Fifth day of January, in the year of our Lord One
thousand eight hundred and sixty.
Signed, sealed, and delivered by the above-
named John Smith, in the presence of
W. TASKER, Patent Agent,
Halifax.
