AN IMPROVED GRATE OR FURNACE BAR APPLICABLE TO THE FIRES OP STEAM ENGINES, FURNACES, BREWING Pans, and OTHER SIMILAR PURPOSES.
Year: 1873

page_text: LETTERS PATENT to George Weston, of Flat Street, Sheffield, in the
County of York, Machinist, for the Invention of "AN IMPROVED
GRATE OR FURNACE BAR APPLICABLE TO THE FIRES OP STEAM ENGINES,
FURNACES, BREWING Pans, and OTHER SIMILAR PURPOSES.'
PROVISIONAL SPECIFICATION left by the said George Weston at the
Office of the Commissioners of Patents, with his Petition, on the
14th November 1873.
I, GEORGE WESTON, of Flat Street, Sheffield, in the County of York,
Machinist, do hereby declare the nature of the said Invention for "An
IMPROVED GRATE OR FURNACE BAR APPLICABLE TO THE FIRES OF STEAM ENGINES,
FURNACES, BREWING PANS, AND OTHER SIMILAR PURPOSES," to be as follows:-
The nature of my Invention or improvement consists in dividing the top
edge or face of the bar into a number of sections, and as far as possible
seperating the top edge from the under edge by longitudinal openings, in
connection with such divisions in the upper edge, in order to allow for
expansion by heat without altering the form of the bar, thereby securing a

page_text: uniform surface, and preventing the too rapid destruction of the bar; and
also in placing the side studs a distance from the top edge or face of the
bar, so as to allow of the slag being removed without obstruction.
SPECIFICATION in pursuance of the conditions of the Letters Patent,
filed by the said George Weston in the Great Seal Patent Office on
the 13th May 1874.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, GEORGE
WESTON, of Flat Street, Sheffield, in the County of York, Machinist,
send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her
Letters Patent, bearing date the Fourteenth day of November, in the
year of our Lord One thousand eight hundred and seventy-three, in the
thirty-seventh 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 "IMPROVED GRATE
OR FURNACE BARS APPLICABLE TO THE FIRES OF STEAM ENGINES, FURNACES,
BREWING PANS, AND OTHER SIMILAR PURPOSES," 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 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 George Weston, 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:―

page_text: My Invention is chiefly designed to prevent the destruction of the
bars, but is an efficient means of effecting a saving in the consumption
of coal, and in minimising the formation of slag.
The nature of my Invention consists in forming the grate or furnace
bars with openings in the upper edge or surface connected with lateral
openings, thereby dividing the upper edges of the bars into sections, so
as to allow for expansion and contraction by heat, and thus preventing
the alteration of form consequent upon the unequal expansion of the
upper and lower edges of the bars, and in protecting the upper edge or
surface of the bar by fixing thereto, either by dovetailing or other means,
short sections of bars made of more durable metal, so as to prevent the
destruction of the bars by burning, the said short sections being easily
replaced by new ones.
Having thus fully described the said Invention, I wish it understood
that I claim,—
First. The breaking of the continuity of the upper surface or edge of
the bar into sections.
Second. The protecting of the said upper edge or surface of the bar,
by moveable pieces or sections of less consumable metal.
In witness whereof, I, the said George Weston, have hereunto set
my hand and seal, this Twenty-eighth day of April, in the year
of any Land One thousand night hundred and savants fou
First. The breaking of the continuity of the upper surface or edge of
the bar into sections.
Second. The protecting of the said upper edge or surface of the bar,
by moveable pieces or sections of less consumable metal.
In witness whereof, I, the said George Weston, have hereunto set
my hand and seal, this Twenty-eighth day of April, in the year
of our Lord One thousand eight hundred and seventy-four.
Signed, sealed, and delivered by
the said George Weston, in
the
presence of
GEO. ERSKINE INOE,
Accountant,
Sheffield.
GEORGE WESTON. (L.S.)
