page_text: .LETTERS PATENT to George Weston, of 19, Flat Street, in Sheffield,
in the County of York, Machinist, for the Invention of "AN IM-
PROVED STEAM GENERATOR, AND IMPROVEMENT IN THE CONSTRUCTION OF STEAM
ENGINE BOILERS, PRINCIPALLY APPLICABLE TO LOCOMOTIVE BOILERS AND IN
APPARATUS THEREFOR.
"
PROVISIONAL SPECIFICATION left by the said George Weston at the
Office of the Commissioners of Patents, with his Petition, on the
13th November 1874.
I, GEORGE WESTON, of 19, Flat Street, in Sheffield, in the County of
York, Machinist, do hereby declare the nature of the said Invention
for "AN IMPROVED STEAM Generator, and ImproVEMENT IN THE CONSTRUCTION OF
STEAM ENGINE BOILERS, PRINCIPALLY APPLICABLE TO LOCOMOTIVE BOLLERS AND IN
APPARATUS THEREFOR," to be as follows :—
The nature of my Invention consists in the application of hot iron or
other metal heaters for the purpose of generating steam instead of the

page_text: usual method of generating steam by means of fire underneath or inside
the tube of the boiler, and in constructing steam engine boilers that the
heaters may be placed in tubes or receptacles formed in the improved
boilers of such shape and in such position as to cause the heat from the
heaters to act upon the water inside of the boiler and thereby generate
steam. The tubes to be (by preference) taper and open at the upper
surface of the boiler so as to allow of the heaters being lowered into such
tubes or receptacles which they are made to fit. The heaters to be of
such size and number as the varying requirements necessitate. The said
Invention to be worked by the use of furnaces for the purpose of
heating the heaters by the use of travelling hydraulic or ordinary cranes
for the purpose of placing the heaters in the tubes or sockets, and of
removing them from the sockets into the furnace for the purpose of
being re-heated; also in the construction of the furnaces so as to provide
a constant supply of hot water for the locomotive boilers and tenders;
also for utilizing the waste steam (now used to create a draft) by using
it to keep the water hot in the tenders and for warming the carriages in
SPECIFICATION in pursuance of the conditions of the Letters Patent,
filed by the said George Weston in the Great Seal Patent Office on 30
the 12th May 1875.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, GEORGE
WESTON, of 19, Flat Strect, in Sheffield, in the County of York,
Machinist, send greeting.

WHEREAS Her most Excellent Majesty Queen Victoria by Her
Letters Patent, bearing date the Thirteenth day of November, in the
year of our Lord One thousand eight hundred and seventy-four, in the
thirty-eighth year of Her reign, did, for Herself, Her heirs and suc-
cessors, give and grant unto me, the said George Weston, Her special
licence that I, the said George Weston, my executors, administrators,
and assigns, or such others as I, the said George Weston, 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 STEAM
GENERATOR, AND IMPROVEMENT IN THE CONSTRUCTION OF STEAM ENGINE BOILERS,
PRINCIPALLY, APPLICABLE TO LOCOMOTIVE BOILERS AND IN APPARATUS THEREFOR,”
upon the condition (amongst others) that I, the said George Weston,
my executors or administrators, by an instrument in writing. under my,
or their, or one of their hands and seals, should particularly describo
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 imme-
diately after the date of the said Letters Patent.
NOW KNOW YE, that I, the said George Weston, 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 :-
My Invention relates to apparatus for generating steam in steam-
engine boilers by the use of metal heaters in lieu of fires, thereby
preventing the pollution of the atmosphere by the emission of the
deleterious products of combustion.
The nature of my Invention consists in the use of metal heaters for
the purpose of generating steam, and in so constructing steam-engine
boilers that the heaters may be placed in tubes or receptacles formed in
the boilers of such shape and in such position as to cause the heat
emitted from the heaters to act upon the water inside the boiler, thereby
generating steam. The tubes or receptacles to be (by preference) taper
and open at the upper surface of the boiler so as to allow the heaters to
be lowered or placed into such tubes or receptacles, the heaters being
made to fit such receptaclés and of such size and in such numbers and

page_text: positions as the varying requirements necessitate. The said Invention
to be worked by means of furnaces in which to heat the heaters, and of
cranes for the purpose of placing the heaters in the tubes or receptacles
when hot, and of removing them from the tubes or receptacles into the
furnaces for the purpose of being re-heated; also in the construction of
the furnaces so as to provide a constant supply of hot water for use in
the locomotive boilers and tenders; also for utilizing the waste steam (at
present used to increase the draft in the furnace) for heating the water
in the tender, and for the further purpose of warming the carriages
when necess
