page_text: LETTERS PATENT to John Shaw, of Hull, in the County-of York,
for the Invention of "IMPROVEMENTS IN HEATING, WHICH IMPROVEMENTS
ARE APPLICABLE TO THE EXHAUSTING OF THE STEAM FROM THE CYLINDERS OF
PROVISIONAL SPECIFICATION left by the said John Shaw at the
Office of the Commissioners of Patents, with his Petition, on the
7th February 1873.
I, JOHN SHAW, of Hull, in the County of York, do hereby declare the
nature of my said Invention for "IMPROVEMENTS IN HEATING, WHICH
IMPROVEMENTS ARE APPLICABLE TO THE EXHAUSTING OF THE STEAM FROM THE
CYLINDERS OF STEAM ENGINES, STEAM HAMMERS, AND OTHER LIKE APPARATUS," to
be as follows :-

page_text: Secondly. The employment of the oxygen in steam (or water
vaporized) as a supporter of combustion in coal or coke fires (including
those for smelting furnaces) for industrial, domestic, social, or navigation
purposes.
Thirdly. The employment of the hydrogen in steam (or water
vaporized) either as hydrogen alone or as a compound of hydrogen with
carbon or with oxygen, or with both carbon and oxygen, as a fuel or
combustible which is consumed on the spot close after its separation or
liberation for producing or generating heat or caloric for industrial,
domestic, social, or navigation purposes.
Fourthly. The employment of the heat or caloric in steam (or water
vaporized) for producing or generating fresh steam, or water vapour) or
for smelting purposes.
Fifthly. The partial or entire exhausting of the steam (or water
vaporized) from the cylinders of steam engines, steam hammers, and
such like apparatus by conveying it after it has exerted its force upon the
pistons from the cylinder or cylinders to the fire.
The peculiar process by which the herein-before named five heads of
Invention, or any one of them, are or is obtained is that of simply
bringing steam (or water vaporized) either by pipes, flues, conduits, or
by any other means which may be found convenient and efficient
directly in contact with coal or coke fires, or by bringing steam into
those parts of a furnace or fire-place where the flame and products of
combustion circulate, or which are connected with the fire or fire-place
when the fuel or combustible therein is in active combustion, and allowing
the escape of the said steam into such fire or fire-place in larger or
smaller quantities, as the state of the fire will admit of, whereby the
oxygen and the hydrogen in the steam (or water vaporized) become
entirely or to some extent disunited or separated, and by combining with
the fuel or combustible and the oxygen from the atmosphere produce
fire, flame, heat, or caloric.
The escape into the fire or furnace of heat or caloric from the steam
(or water vaporized) fulfils the fourth object of my Invention, and the
affinity of the fire or combustible for the elements of the steam (or water
vaporized) coupled with the rarified atmosphere of the fire fulfils when
the steam is conveyed from the cylinder or cylinders to the fire the fifth
object of my said Invention.

page_text: Any one or more of the said features or objects of my Invention, or
some or all of them combined constitute along with the peculiar process
herein-before described by which they are obtained the essential features
of this Invention.
SPECIFICATION in pursuance of the conditions of the Letters Patent,
filed by the said John Shaw in the Great Seal Patent Office on the
7th August 1873.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, JOHN SHAW,
of Hull, in the County of York, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her
Letters Patent, bearing date the Seventh day of February, in the
year of our Lord One thousand eight hundred and seventy-three, in
the thirty-sixth year of Her reign, did, for Herself, Her heirs and
successors, give and grant unto me, the said John Shaw, Her special
license that I, the said John Shaw, my executors, administrators,
and assigns, or such others as I, the said John Shaw, my executors,
administrators, or assigns, should 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
HEATING, WHICH IMPROVEMENTS ARE APPLICABLE TO THE EXHAUSTING OF THE
STEAM FROM THE CYLINDERS OF STEAM ENGINES, STEAM HAMMERS, AND OTHER
LIKE APPARATUS," upon the condition (amongst others) that I, the said
John Shaw, my executors or administrators, by an instrument in
writing under my hand and seal, 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 Shaw, do hereby declare the
nature of my said Invention, and in what manner the same is to bo
performed, to be particularly described and ascertained in and by the
following statement, that is to say:-

page_text: My said Invention has for its object,―
First. The partial or entire separation of the oxygen and hydrogen in
steam (or water vaporized) for the purposes herein-after specified.
Secondly. The employment of the oxygen in steam (or water
vaporized) as a supporter of combustion in fires of coal, coke, or other
combustibles (including those for smelting furnaces) for industrial,
domestic, social, or navigation purposes.
Thirdly. The employment of the hydrogen in steam (or water
vaporized) either as hydrogen alone or as a compound of hydrogen with
carbon or with oxygen, or with both carbon and oxygen as a fuel or
combustible which is consumed on the spot close after its separation or
liberation for producing or generating heat or caloric for industrial,
domestic, social, or navigation purposes.
Fourthly. The employment of the heat or caloric in steam (or water
vaporized) for producing or generating fresh steam (or water vapor) or
for smelting purposes.
Fifthly. The partial or entire exhausting of the steam (or water
vaporized) from salt pans and other evaporators, also from the cylinders.
of steam engines, steam hammers, and such like apparatus by conveying
it after it has exhausted its force upon the pistons from the cylinder or
cylinders to the fire.
The peculiar process by which the herein-before named five heads of
Invention or any one of them are or is obtained is that of simply
bringing steam (or water vaporized) either by means of pipes or conduits,
or by any other means which may be found convenient and efficient into
a fire of coal, coke, or other combustible, or into those parts of a furnace
or fire-place where the flame and products of combustion circulate, so as
to superheat the steam (or water vaporized) whilst in the said pipes or
conduits, and then allow the escape of the said steam as it becomes
superheated direct into the said fire or fire-place when the fuel or com-
bustible therein is in active combustion in larger or smaller quantities,
as the state of the fire will admit of, whereby the oxygen and the
hydrogen in the steam (or water vaporized) become entirely or to some
extent disunited or separated, and by combining with the fuel or com-
bustible and the oxygen from the atmosphere produce fire, flame, heat,
or caloric.

page_text: The escape into the fire or furnace of heat or caloric from the steam
(or water vaporized) fulfils the fourth object of my Invention, and the
affinity of the fire or combustible for the elements of the steam (or water
vaporized) coupled with the rarified atmosphere of the fire fulfils the fifth
object of my Invention, when the steam is conveyed from salt pans or
other evaporators, or from the cylinder or cylinders of a steam engine or
steam hammer to the fire.
Having now described and particularly ascertained the nature of my
said Invention, and the manner in which the same is or may be used or
carried into effect, I would observe in conclusion that what I consider
to be novel and original and therefore claim as the Invention secured to
me by the herein-before in part recited Letters Patent is,―
First. The superheating of steam and bringing the same directly in
contact with fires of coal, coke, or other combustible, or into combustion
chambers, substantially in the manner and for the specific purposes
herein-before described.
Second. The mode of exhausting the steam from salt pans and other
evaporators, and from the cylinders of steam engines, steam hammers,
and other like apparatus, as herein-before described.
In witness whereof, I, the said John Shaw, have to this my Specifi-
cation set my hand and seal, this Sixth day of August One
thousand eight hundred and seventy-three.
Witness,
W. A. SHAW.
JOHN SHAW. (L.S.)
