AN IMPROVED METHOD OF GENERATING STEAM IN LOCOMOTIVE, STATIONARY, MARINE, OR ANY OTHER FORM OF STEAM BOILER
Year: 1860

page_text: LETTERS PATENT to Peter Brotherhood, of Chippenham, in the County
of Wilts, Railway Engineer, for the Invention of "AN IMPROVED METHOD
OF GENERATING STEAM IN LOCOMOTIVE, STATIONARY, MARINE, OR ANY OTHER
FORM OF STEAM BOILER."
Sealed the 24th August 1860, and dated the 17th March 1860.
PROVISIONAL SPECIFICATION left by the said Peter Brotherhood at the
Office of the Commissioners of Patents, with his Petition, on the 17th
March 1860.
I, PETER BROTHERHOOD, of Chippenham, in the County of Wilts, Railway
Engineer, do hereby declare the nature of the said Invention for "AN
IMPROVED METHOD OF GENERATING STEAM IN LOCOMOTIVE, STATIONARY, MARINE, OR
ANY OTHER FORM OF STEAM BOILER," to be as follows:-
My Invention consists in taking steam from the boiler and passing it by
means of a pump, or other suitable forcing apparatus, through a super-
heating apparatus, in which it is raised to a high degree of temperature. The
steam thus heated is returned into the boiler (at the lowest possible point)
through a perforated pipe or pipes; in rising through the water to its surface
the heat imparted to the steam will generate fresh steam, thus increasing the
evaporative power of the boiler, and consequently saving fuel.

by the said Peter Brotherhood in the Great Seal Patent Office on the
14th September 1860.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, PETER
BROTHERHOOD, of Chippenham, in the County of Wilts, Railway Engineer,
send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her Letters
Patent, bearing date the Seventeenth day of March, in the year of our
Lord One thousand eight hundred and sixty, in the twenty-third year of Her
reign, did, for Herself, Her heirs and successors, give and grant unto me,
the said Peter Brotherhood, Her special licence that I, the said Peter Brother-
hood, my executors, administrators, and assigns, or such others as I, the
said Peter Brotherhood, my executors, administrators, and 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 "AN
IMPROVED METHOD OF GENERATING STEAM IN LOCOMOTIVE, STATIONARY, MARINE, OR
ANY OTHER FORM OF STEAM BOILER," upon the condition (amongst others)
that I, the said Peter Brotherhood, 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 Peter Brotherhood, do hereby declare
the nature of the said Invention, and in what manner the same is to be
performed, to be particularly described and ascertained in and by the following
statement thereof, that is to say:-
My Invention of an improved method of generating steam, which is
applicable to locomotive, stationary, marine, or any other description of steam
boiler, consists in taking a portion of steam from the boiler, and passing the
*said steam by means of a pump, or other suitable forcing apparatus, (worked
by the engine or otherwise,) into and through a superheating apparatus
connected with a smoke box, or with a furnace. In its passage through the
superheating apparatus the steam will be raised to a higher degree of
temperature, in which state it is to be returned into the boiler through a per-
forated pipe or pipes, arranged and disposed at the lowest part of the boiler.

page_text: In rising through the water to its upper surface, the superior heat which has
been given to the returned steam will be imparted to the water, and cause the
evolution of an additional quantity of steam, thereby greatly increasing the
steam-producing power of a boiler of given dimensions, and effecting a
considerable saving of fuel.
It will be evident that the manner of performing this, my Invention, may
be varied in many ways to suit the peculiar requirements of each case, but I
wish it to be understood, that what I claim as my Invention is, the method of
taking steam from the boiler, and after passing it through a superheating
apparatus returning it into the water of the same (or another) boiler, in the
manner and for the purpose herein-before described.
In witness whereof, I, the said Peter Brotherhood, have hereunto set
my hand and seal, this Tenth day of September, in the year of
our Lord One thousand eight hundred and sixty.
PETER BROTHERHOOD. (L.S.)
