Year: 1875

page_text: LETTERS PATENT to Robert Newton, of Lower Providence Mills,
Keighley, in the County of York, for the Invention of "IMPROVE-
MENTS IN APPARATUS FOR SUPPLYING FUEL TO STEAM BOILER AND OTHER
FURNACES."
Sealed the 7th March 1876, and dated the 9th September 1875.
PROVISIONAL SPECIFICATION left by the said Robert Newton at the
Office of the Commissioners of Patents, with his Petition, on the
9th September 1875.
I, ROBERT NEWTON, of Lower Providence Mills, Keighley, in the
County of York, do hereby declare the nature of the said Invention
for "IMPROVEMENTS IN APPARATUS FOR SUPPLYING FUEL TO STEAM BOILER AND
OTHER FURNACES," to be as follows:-
This Invention relates to further improvements upon an Invention
for which Letters Patent were granted to me, dated November 6th 1867,
No. 3131, intituled "Improvements in Fuel Feeding Apparatus' for
Steam Boilers," and my present improvements consist in the application

page_text: of slides or regulators applied to the thoroughfare or passage through
which the fuel passes before reaching the grate bars. These slides are
for the purpose of regulating the supply or distribution of fuel, and by
the use of them the fuel can be directed to any particular part of the
crate bars as may be desired.
SPECIFICATION in pursuance of the conditions of the Letters Patent,
filed by the said Robert Newton in the Great Seal Patent Office
on the 9th March 1876.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, ROBERT
NEWTON, of Lower Providence Mill, Keighley, in the County of York,
send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her
Letters Patent, bearing date the Ninth day of September, in the year
of our Lord One thousand eight hundred and seventy-five, in the
thirty-ninth year of Her reign, did, for Herself, Her heirs and
successors, give and grant unto me, the said Robert Newton, Her
special licence that I, the said Robert Newton, my executors, admini-
strators, and assigns, or such others as I, the said Robert Newton,
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
“IMPROVEMENTS—-IN-APPARATUS-FOR-SUPPLYING FUEL TO STEAM BOILER AND OTHER
_FURNACES," upon the condition (amongst others) that I, the said
Robert Newton, 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 VE that I the said Robert Newton do hereby declara.

page_text: to be performed, to be particularly described and ascertained in and
by the following statement and accompanying Sheet of Drawings (that
is to say):
This Invention relates to further improvements upon an Invention.
for which Letters Patent were granted to me, dated November 6th 1867,
No. 313, intituled "Improvements in Fucl Feeding Apparatus for
Steam Boilers," and my present improvements consist in the application
of slides or regulators applied to the thoroughfare or passage through
which the fucl passes before reaching the grate bars. These slides are
for the purpose of regulating the supply or distribution of fuel, and by
the use of them the fuel can be directed to any particular part of the
grate bars as may be desired.
The accompanying Drawing represents the front part of a supply or
distributing box from which the fuel is supplied to the grate bars, the
opening in the box being represented by the dotted lines A, B; C and D
are slides working on studs E and F, and moved to and fro by screws
G and H passing through lugs or bushes J and K. If fuel is being
distributed too freely at either side of the grate bars, by moving the
slide on that side a little forward the supply is checked or thrown more
towards the centre of the grate, and the combustion of fuel is carried on
with greater uniformity and economy.
I do not confine myself to the method herein shown for operating the
slides, as it may be varied, but what I claim as my Invention is the
application and use of slides or regulators as and for the purpose herein
shewn and described.
In witness whereof, I, the said Robert Newton, have hereunto set
my hand and seal, this Sixth day of March, in the year of our
