page_text: LETTERS PATENT to Emanuel Bradley, Humphrey Bradley, and William
Sunderland, all of Morley, near Leeds, in the County of York, for the Inven-
tion of IMPROVEMENTS IN THE MEANS OR APPARATUS FOR CONSUMING
SMOKE AND ECONOMISING FUEL."
Sealed the 20th October 1877, and dated the 12th May 1877:
PROVISIONAL SPECIFICATION left by the said Emanuel Bradley, Humphrey
Bradley, and William Sunderland at the Office of the Commissioners of

EMANUEL BRADLEY, HUMPHREY BRADLEY, and WILLIAM SUNDERLAND, all of
Morley, near Leeds, in the County of York. "IMPROVEMENTS IN THE MEANS OR
APPARATUS FOR CONSUMING SMOKE AND ECONOMISING FUEL."
The improvements have particular reference to our Invention entitled " 'Improve-
ments in the Means or Apparatus for Economising Fuel, and for the Consumption
of Smoke," for which Letters Patent were granted to us, bearing date the 15th
March, 1876, No. 1116, and is as.hereafter described.
Instead of having an open space between the grate bars and dead plate, as
specified in the Specification of the above-mentioned Patent, we attach a number of
bars to the dead plate in an angular direction, the outer end thereof meeting the
short bars named in the Specification of the above Patent, and resting on the same
bearer. These angular bars are by preference cast on the dead plate, but when
required may be attached thereto by ordinary means. These bars are varied in
size to admit a suitable quantity of air for the purpose of burning the smoke or
inflammable gases.

page_text: By their application also the fire or heat can be got up much quicker, and coal or
other fuel of a very inferior quality may be burned.
SPECIFICATION in pursuance of the conditions of the Letters Patent filed by
the said Emanuel Bradley, Humphrey Bradley, and William Sunderland in the
Great Seal Patent Office on the 12th November 1877.

APPARATUS FOR CONSUMING SMOKE AND ECONOMISING FUEL."
The improvements have particular reference to our Invention entitled " Improve-
ments in the Means or. Apparatus for Economising Fuel, and for the Consumption
of Smoke," for which Letters Patent were granted to us, bearing date the 15th
March, 1876, No. 1116, and are as hereafter described.
Instead of having an open space between the grate bars and dead plate, as
specified in the Specification of the above-mentioned Patent, we attach a number of
bars to the dead plate in an angular direction, the outer end thereof meeting the
short bars named in the Specification of the above Patent, and resting on the same
bearer. These angular bars are by preference cast in the dead plate, but when
required may be attached thereto by ordinary means. These bars are varied in
size to admit a suitable quantity of air for the purpose of burning the smoke or
inflammable gases.
.
By their application also the fire or heat can be got up much quicker, and coal or
other fuel of a very inferior quality may be burned.
And in order that our Invention may be more completely understood reference
is given to the accompanying Drawings, and to the letters and marks thereon.
Figure 1 is a longitudinal section and Figure 2 is a sectional plan of so much of
furnace as will be necessary to illustrate the manner of carrying our Invention
into effect.
a is the interior of the furnace; b and c are grate bars, constructed in accordance
with our Patent bearing date the 15th March, 1876, No. 1116.
Instead of having an open space between the grate bars b and c and dead plate d,
as shown in Specification of above-mentioned Patent, we attach a number of
bars e to the dead plate d, as shown, the outer ends f meeting the short bars b and
resting on the same bearer g. These angular bars are by preference cast on the
dead plated, but when required may be attached thereto by ordinary means. These
bars é are varied in size to admit of a suitable quantity of air for the purpose of
burning the smoke or inflammable gases.
By their application also the fire or heat can be got up much quicker, and coal or
other fuel of a very inferior quality may be burned.
Having now described the nature of our said Invention, and shown by Drawings
how the same may be carried into practice, we would have it understood that we
do not limit ourselves to the exact limits, details, or configuration of the various
parts we have expressed and shown, as the same may be varied or modified without
in any way departing from our Invention; but what we do claim and desire to be
secured to us by Letters Patent is,--
First. The arrangement and application of bars e placed in a more or less angular
direction, substantially as herein set forth.
Second. The combination of the various parts of the improved apparatus employed

page_text: for the economising of fuel and consumption of smoke, substantially as herein set
forth.
In witness whereof, I, the said William Sunderland, for myself and on behalf
of the said Emanuel Bradley and Humphrey Bradley, have hereunto set my
hand and seal, this Ninth day of November, in the year of our Lord One
thousand eight hundred and seventy-seven.
