FOARD, of Queen's Head Lane, Islington, Machinist, send greeting.
WHEREAS Her present most Excellent Majesty Queen Victoria, by Her
Letters Patent under the Great Seal of Great Britain, bearing date at West-
minster, the Sixteenth day of January, in the fourth year of Her reign, did,
for Herself, Her heirs and successors, give and grant unto me, the said Edward
Foard, Her especial licence, full power, sole privilege and authority, that I, the
said Edward Foard, my executors, administrators, and assigns, or such others
as I, the said Edward Foard, my executors, administrators, or assigns, should
at any time agree with, and no others, from time to time and at all times
during the term of years therein expressed, should and lawfully might make,
use, exercise, and, vend, within England, Wales, and the Town of Berwick
upon Tweed, my Invention of "AN IMPROVED METHOD OR IMPROVED METHODS OF
SUPPLYING FUEL TO THE FIRE-PLACES OR GRATES OF STEAM-ENGINE BOILERS,
BREWERS' COPPERS, AND OTHER FURNACES, AS WELL ALSO TO THE FIRE-PLACES EM-
PLOYED IN DOMESTIC PURPOSES, AND GENERALLY TO THE SUPPLYING FUEL TO FURNACES
FIRE-PLACES, IN SUCH A MANNER AS TO CONSUME THE SMOKE GENERALLY PRODUCED
IN SUCH FURNACES OR FIRE-PLACES;" in which said Letters Patent is contained a
proviso that I, the said Edward Foard, should cause a particular description
of the nature of my said Invention, and in what manner the same is to be per-
formed, to'be'inrolled in Her said Majesty's High Court of Chancery within

closing of an, opening into the fire-place or furnace over the, chamber or oven.
A rack m is affixed on the under side of the sliding plate l, and motion is com
municated to the sliding plate 7 by means of the crank.handle n affixed on the
axis or. shaft o, such shaft or axis turning in bearings P, as is shown. 9 is a
bevel toothed wheel affixed on the axis or shaft o. The wheel ģ takes into:
and drives a wheel affixed on the short axis sand on the same axis-si is
affixed the toothed wheel t, which takes into the rack m, and by such means,
the sliding plate l may be moved over the chamber, or coking oven, or, with-
drawn therefrom, as occasion may require. Supposing the furnace. to have been
at work some time, and the piston to have been raised to its highest position;
the mode of supplying. fresh fuel is as follows:-The..sliding. plate l, which
has been out of use during the time that the previous charge of fuel in the
chamber or coking oven has been progressively raised. and. supplied into the
furnace, is now to be slided over the coking oven, or chamber, and conse-
quently under the burning fuel of the furnace.. By this means the burning
fuel over the chamber or coking oven will be supported; and allow of the
piston being lowered, in order to receive a supply of fuel thereon, which will
readily be supplied through the doorway in front of the chamber or coking
oven, as above described. The chamber or coking oven- being charged, the
door is to be closed, and fastened, and the piston raised so as to bring the fresh
fuel close under the sliding plate l; that plate is then to be withdrawn, and it
will remain out of use until the piston has again been raised to its highest
position, when it will again be slided in to sustain the burning fuel above the
chamber or coking oven, and thus again allow of the piston descending to have
fresh fuel supplied into the coking oven or chamber as before described. .I will
now proceed to describe another arrangement of furnace with apparatus for sup-
plying fuel thereto very similar to that above described, but differing inasmuca
there being no sliding plate l, but a temporary plate which acts in place thereof
to sustain the fuel, which is above the chamber or coking oven when the
piston has to descend, in order to there being a fresh supply of fuel fed into
the coking oven or chamber. Figure 6 shews a longitudinal section of a steam
boiler and furnace with my Invention applied thereto... Figure 7 is a front end
view, and Figure 8 is a transverse section, of the boiler and furnace." In these
Figures the same letters are used to indicate the similar parts to those described
in the previous Drawings, and it will not be necessary again to describe such
parts, as their mode of working has been already described.
In this arrange-
inent of my Invention the sliding plate 7 before described is dispensed with,
and the temporary plate used in place thereof. w are four spring or lever

page_text: stops or supports, their upper ends passing through openings formed at the
sides of the chamber or coking oven, and such upper ends have at all times a
tendency by their springs to remain within the chamber or coking oven, as
will readily be understood, on examining the Drawings now under descrip-
tion. The door at the front of the chamber or coking oven is divided into
two parts, the smaller part being at the top, and this is to allow of the plate v
being withdrawn, when a fresh supply of fuel has been fed into the coking
oven or chamber. In working this arrangement, supposing. the fire to have
been at work some time, and that the plate v, resting on the piston c, has been
raised to its highest position, it will have passed the upper ends of the spring
or lever stops or supports, and will be supported thereby, there being notches.
formed in the piston opposite the spring and stops or supports, so as to allow
the spring stops or supports coming under the. plato v, so soon as that plate
has passed above those stops or supports; the burning fuel will now be sup-
ported above the plate v, and the piston may be lowered down in order to
admit of a fresh supply of fuel to the chamber or coking oven through the
door way in front, as before described. There being a plate v first placed on
the piston, the chamber being charged, the doors are then to be closed, and
the piston raised so as to bring the fresh supply of fuel under the plate v, when
the upper part of the door is to be opened, and the upper plate v drawn out by
a hook or other convenient instrument, and in this manner is the furnace to bé
worked. I have not thought it necessary to shew furnaces applied to other
than a steam boiler for a fixed steam engine, as it is well known that a furnace
for locomotive or for marine steam engines, and for a brewer's copper, or for
other boiling and evaproating vessels, will not materially vary from that shewn;
indeed the arrangement of furnaces are so similar one to another for whatever
purpose they may be applied, that a workman capable of constructing a furnace
for a particular object will readily apply my Invention thereto, from the descrip-
tion above given, aided by the Drawings annexed.
I will now describe my Invention as applied to open fire-places. Figure 9
shews a front view of a cooking range having my Invention applied thereto, and
the parts are similar to the arrangements shewn in Figures 1, 2, 3, 4, and 5, being
only so modified as to adapt them to this description of fire-place. But I would
remark, that if preferred, the plate v may be used in place of the plate 7, which
is shewn by varying the parts accordingly. Figure 10 is a transverse section of
Figure 9. The parts employed in applying my Invention, as shewn in Figures 9
and 10, being marked with the same letters of reference as those of Figures 1,
2, 3, 4, and 5, the description of those parts before given will be sufficient to
describe the nature and use of the parts shewn in Figures 9 and 10, when

of the construction of the parts in order to render them suitable for stoves and
open fire-places.
my
Having thus described the nature of my Invention, and the manner in
which the same is to be performed, I would remark that although I have been
particular in describing the best means I am acquainted with for carrying out
my Invention, I do not confine myself to the precise details shewn and
described, as they may be varied, so long as the peculiar character of Inven-
tion be retained, and I am aware that it is not new to supply fuel from below
upwards into furnaces and fire-places by means of a chamber or piston or
platform working therein, as similar means were described in the Specification
of a Patent granted to John Cutler, of Great Queen Street, Lincoln's Inn
Fields, on the Sixth day of January, One thousand eight hundred and fifteen.
I do not therefore claim the same, nor do I claim any of the parts above de-
scribed separately, or except as combined, to produce my Invention; but what I
claim is, first, the application of a door to the chamber or coking oven to facili-
tate the supplying fuel thereto, as above described; secondly, I claim the mode
of supporting the fuel by means of the plate or surface, when that plate or
surface is used in combination with a piston and chamber or oven such as are
herein described; and, thirdly, I claim the mode of applying a plate v working
within the chamber or coking oveň, as above described.
In witness whereof, I, the said Edward Foard, have hereunto set my
hand and seal, this Sixteenth day of July, in the year of our Lord One
AND BE IT REMEMBERED, that on the same Sixteenth day of July, in
the year above mentioned, the aforesaid Edward Foard, came before our Lady
the Queen in Her Chancery, and acknowledged the Specification aforesaid, and
all and everything therein contained, in form above written. And also the
Specification aforesaid was stamped according to the tenor of the Statute in
that case made and provided.
Inrolled the same Sixteenth day of July, in the year above written.
