Year: 1856

page_text: LETTERS PATENT to Frederick William Anderton, of Bradford, in the
County of York, Worsted Spinner, and Joseph Beanland, of the same
Place, Engineer, for the Invention of "IMPROVEMENTS IN APPARATUS OR
MEANS IN CONNECTION WITH FURNACES TO FACILITATE THE CONSUMPTION OF
Sealed the 24th, April 1857, and dated tho 11th December 1856.
PROVISIONAL SPECIFICATION left by tho said Frederick William Anderton
and Joseph Beanland at the Office of the Commissioners of Patents, witli
their Petition, on the 11th December 1856.
We, FREDERICK WILLIAM ANDERTON, of Bradford, in the County of York;
Worsted Spinner, and JOSEPH BEANLAND, of the same Place, Engineer, do
hereby declare the nature of the said Invention for "IMPROVEMENTS IN APPARATUS
OR MEANS IN CONNECTION WITH FURNACES TO FACILITATE THE CONSUMPTION OF
SMOKE," to be as follows:-
The improvements relate to a combination of means for the admission of air
to the fire-place, and consist, when using hollow fire bars, in conducting
atmospheric air thereto through bell or funnel-shaped or other suitable con-
ductors to the inner ends of such bars, in order that such air may traverse the
bars to the front ends of them, where there are openings, to admit of its escape
into the firé-place in front of the fuel therein, and there is a valve or flap
which is operated upon by the opening and closing of the fire door, so that

page_text: such valve or flap may, by covering, close these openings when the door is
open, to prevent their being stopped up by the fresh fuel at the time of supply,
and then, by uncovering, open them again so soon as the door is closed; and
when these passages are thus open, the supply of air which has become
heated in its passage through the hollow bars takes place. In place of only
valve or flap, there may be several of them, and such valves or flaps, by
turning on hinge joints, also serve, according to the inclination given them, to
deflect the air on to the burning fuel (or the flame therefrom) at any angle
desired, and prevent its passing direct upon and thereby injuring the boiler.
SPECIFICATION in pursuance of the conditions of the Letters Patent, filed
by the said Frederick William Anderton and Joseph Beanland in the
Great Seal Patent Office on the 11th June 1857.
TO ALL TO WHOM THESE PRESENTS SHALL COME, we, FREDERICK
WILLIAM ANDERTON, of Bradford, in the County of York, Worsted Spinner,
and JOSEPH BEANLAND, of the same Place, Engineer, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her Letters
Patent, bearing date the Eleventh day of December, in the year of our
Lord One thousand eight hundred and fifty-six, in the twentieth year of Her
reign, did, for Herself, Her heirs and successors, give and grant unto us, the
said Frederick William Anderton and Joseph Beanland, Her special licence
that we, the said Frederick William Anderton and Joseph Beanland, our
executors, administrators, and assigns, or such others as we, the said
Frederick William Anderton and Joseph Beanland, our executors, adminis-
trators, 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 OR MEANS IN CONNECTION
WITH FURNACES TO FACILITATE THE CONSUMPTION OF SMOKE," upon the condition
(amongst others) that we, the said Frederick William Anderton and Joseph
Beanland, our executors or administrators, by an instrument in writing under
our or their hands and seals, or under the hand and seal of one of us or them,
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.

page_text: NOW KNOW YE, that we, the said Frederick, William Anderton and
Joseph Beanland, 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:-
The improvements relate to a combination of means for the admission of air
to the fire-place, and consists, when using hollow fire bars, in conducting
atmospheric air thereto through bell or funnel-shaped or other suitable con-
ductors to the inner ends of such bars, in order that such air may traverse the
bars to the front ends of them, where there are openings to admit of its escape
into the fire-place in front of the fuel therein. And there is a valve or flap
which is operated upon by the opening and closing of the fire door, so that
such valve or flap may, by covering, close these openings when the door is
open, to prevent their being stopped up by the fresh fuel at the time of supply,
and then, by uncovering, open them again so soon as the door is closed, and
when these passages are thus open, the supply of air which has become heated
in its passage through the hollow bars takes place.
In place of only one valve or flap, there may be several of them, and such
valves or flaps, by turning on hinge joints, also serve, according to the inclination
given them, to deflect the air on to the burning fuel (or the flame therefrom)
at any angle desired, and prevent its passing direct upon and thereby injuring
the boiler.
But that the nature of our said Invention, and the means wo adopt in
carrying the same into effect, may be more fully understood, we will proceed to
describe the Drawing annexed.
DESCRIPTION OF THE DRAWING.
Figure 1 shews a section, and Figure 2 a plan view of a boiler with
furnaces arranged according to our improvements. The plan shows the boiler
to have two fire-places A, B; and in the one (A), the bars and other parts are
shown in their places complete, whilst in the other fire-place (B), the bars and
some other of the parts are removed, in order that parts otherwise covered
may be more fully seen. a, a, are the hollow furnace bars which recoive air
into them by the funnels or bell-shaped conductors 6; but other suitable
conductors may be employed to conduct the atmospheric air to the hollow bars.
The atmospheric air having traversed the bars to the front ends of them,
escapes by the openings c to the fuel in the fire-place, and there is a valve or
flap d at this point, which turns upon a binge joint e, to deflect the heated air
as it passes out from the open ends of the fire bars upon the fuel in the fire-
place. This valve or flap d is acted upon to open or close it by the closing or

page_text: opening of the fire door f, in the following manner :-Upon the lower side of
the furnace door is affixed a wheel or pulley f', which, as the door is closed,
comes upon the upper part of the rod g to depress it, and the lower end of the
rod g is by a pin joint connected to the one end of the lever h, which turns
upon the axis of motion h', and at its other end is connected to a projection
from the valve or flap d, as shown. Consequently, when the furnace door
is opened, and the pressure of the wheel f¹ is removed from the upper end of
the rod g, the flap or valve d is allowed to fall, thereby closing the opening to
the hollow bars to prevent accumulation of fuel within the flaps; at the same
time any fuel or dust which may accumulate therein is allowed to escape by
the passages in the plate under the plato d.
. Having thus described the nature of our said Invention, we would have it
understood that we do not confine ourselves to the precise details of the
parts as herein shewn and described, as these may be varied, so long as the
adaptation or combination of parts, acting in manner and for the purpose
substantially as explained, be retained.
In witness whereof, we, tho said Frederic William Anderton and Joseph
Beanland, have hereunto set our hands and seals, this Ninth day of
June, in the year of our Lord One thousand eight hundred and fifty-
saven
