Road, in the County of Middlesex, Stove Grate Manufacturers, send greeting.
WHEREAS His most Excellent Majesty King George the Third did, by
His Letters Patent under the Great Seal of the United Kingdom of Great
Britain and Ireland, bearing date at Westminster, the Third day of March,
in the forty-eighth year of His reign, give and grant unto us, the said John
Cowden and John Partridge, our exors, adiñors, and assigns, His especial
licence, full power, sole privilege and authority, that we, the said John
Cowden and John Partridge, our exors, admors, and assigns, during the term
of years therein mentioned, should and lawfully might make, use, exercise,
and vend, within England, Wales, and the Town of Berwick-upon-Tweed,
our Invention of "CERTAIN IMPROVEMENTS IN REGISTER AND OTHER STOVES;" in
which said Letters Patent there is contained a proviso obliging us, the said
John Cowden and John Partridge, by an instrument in writing under our
hands and seals, or under the hand and seal of one of us, to cause a particular
description of the nature of our said Invention, and in what manner the same
is to be performed, to be inrolled in His Majesty's High Court of Chancery
within one calendar month after the date of the said recited Letters Patent,
as in and by the same, relation being thereunto had, may more fully and at
large appear.
NOW KNOW YE, that in compliance with the said proviso, we, the said
John Cowden and John Partridge, do hereby declare that our said Invention

page_text: is described and ascertained in and by the Drawings hereunto annexed, and
the following description thereof, that is to say:-
Fig. 1st, a fron view of a register stove. A, the backs and bottom, which,
after failing, rise back again by moving the top of tho falling back towards the
spring catch E, Section 2d, with tho point of a poker or other convenient
instrument. The spring catch then holds them up by means of a staple m or
other fastening on the back, which it slips into or fastens on; or the backs or
bottom may be made to wind up with rack and pinion. K, the front of drawer,
made of lock plate, as high up as the bottom of the fret on the front, sides,
and back from the hearth, with two handles or knobs, one one each sido of a
falling door h in the centre, to sweep the ashes into the drawer which fall on
the hearth in front. I, tho winder.
Section 1. A, an iron back, with an inside stove back to move on an axis
B, with one or two levers to work behind the stove cheek or cheeks, or on
each side to fall with the bottom, and rise with it, to let down the backs and
bottom, by touching the spring catch E fixed to the back frame, above the
falling backs. The axis of the falling backs is fixed about the top of the fire;
the backs fall forward at top above the fire, and backward below the axis (sec
B, Section 3). By touching the spring catch with the point of a poker bit tho
backs and bottom will fall, which admits of sufficient room or space behind for
the fire to fall through into a drawer or other receptacle. C, the bottom,
when let down. a and p the iron loop and levers that fall or raise it up.
The back part of the bottom goes into the drawer I near the front of it, to
discharge the fire, and is then raised up with a poker or other instrument
against the front of the falling back, near the top. G, the side view of
sloping plate, with the bottom down resting on it. F, I, sides of drawer, to
fit close against sides of the back flue. 0, 0, 0, 0, sides of the back flue, which
extend from the top to the bottom of the cheeks, and slope off half way behind,
at the top.
Section 2. A, side view of the falling backs when not let down, with the
backs square in their places to hold the fire and the bottom up close to the backs.
C, the bottom when raised up in its place with the poker against the back for
the grate to hold the fire. E, side view of the spring catch, with the backs
and bottom up, the staple m in catch, as it is when the back is not let down.
F, top valve in back flue of plate iron, and fixed against the axis of backs, to
move up by the motion of the falling backs, to admit the smoak and dust up
the back flue when the fire is discharged, as at F, Section 1, and to return
down by the reverse motion of the backs, and shut up the flue, as at F, to
extinguish the fire. The bottom valve of plate iron is made with two hinges

page_text: at top. The rod, with a joint at each end, forces down the bottom valve by
the weight of the top valve. G, a straight iron sloping plate, the bottom edge
level with the top of drawer, to confine the fire from the air when out of the
grate, fixed to the stove cheeks with four or more screws, the front top edge
about two or three inches further back than the bottom rail of the stove, and
to range with it in front, to slope as low as the bottom of the fret, the opening
f, between the bottom rail and front of the plate, to admit the heat and
light from the bottom of the fire to the hearth. H, an iron rack and pinion, to
wind up the valves to lessen the draft of fire, made to wind on the right cheek,
(as at H, Fig. 1,) two iron loops for the rack to work in, and the rack
set off at two places at bottom, (g, g.) to bring the end under the top valve to
raise them up or let them down. 0, 0, 0, 0, sides of the back flue (see
Section 1).
Section 3. B, an iron lever at one end of the axis, or at both ends if
necessary, fixed behind the falling backs. The lever or levers work inside or
outside the stove checks by the falling or rising of the backs and bottom.
P, an iron rod, with a loop at each end of the lever to raise or fall the bottom.
C, the stove bottom (made cither eliptic in front, circular, or straight), is the
width of the falling backs behind, and has an iron or steel lever fixed at one
end, or at both ends if necessary, to raise the bottom up or let it down. The
iron levers at bottom go through the iron loop a, or two loops if necessary, and
is fastened on with one or two nuts, or in any other convenient way, so as to
act with the lever above the loops, the axis, and falling backs. b, b, hooks
and hinges under the front edge, to work the bottom, part of which are fixed
to the hanging rail of stove; but when the bars and rail take off or draw off,
the part of the hinge that fits on the rail is fixed to an iron frame under the
bottom, instead of being fixed to the rail.
Section 4. D, D, iron plates, one with a socket in centre for the ends of
axis to work in, with two holes for screwing it to the back frame N (sce
Section 5), the other with a socket at one end, and cut through for the axis
to take out, with two holes at bottom for screwing it against the back frame N,
and is fixed with square head, counter-sunk, or round-headed screws, or the
same may be rivetted on the back frame.
Section 5. B, iron axis, which works the lever or levers fastened to the
falling backs behind, and is the width of the falling backs, and moves round
with them. I, the back of drawer, made to fit into back flue O, eight or more
inches beyond the falling back frame M.
N, the iron frame of the stove
backs, to which the iron sockets D, D, are fastened, and which the axis and
backs turn on, and on which the spring catch E acts.

page_text: Section 6. I, the inside of the draw, of an oblong form, the bottom of the
draw and front made of lock plate iron, the sides and back of single plate
iron, and rivetted or otherwise fastened together to contain the fire cinders
and dust.
Fig. 2. L, L, two circular wiro shades, or they may be of iron, steel, or
brass, made to draw out on each side the fire, and to slide back into a recess
on each side the chimney, with two iron loops at the top corners of each side
of the shades, (see i, i, i, i, Section 7). The same letters L, L, in Section 1
and 2, shew the front and back upright standards of the shades, which are
straight as high up as the inside of top piece of the stove front, and then
turned off square inside towards the guides M (in Section 1 and 2), with round
hoops which move on the circular guide M, M (see Section 7)..
Section 7. L, L, the top of the left-hand shade when drawn out with the
end loops which work on the circular guide M, and the right-hand shade in the
recess. M, M, a circular guide for the four loops i, i, i, i, of shade to slide on,
with an iron stay k to fasten each end of the guide, rivetted or fastened to
back flue, to rest on or go through the stove cheeks on each side, and to rest
behind the top piece of stove front in the centre. O, the back flue, half
covered at top. The width is the same as the drawer at bottom, (see I,
Section 5,) and contracts above the drawer to the width of the back frame N,
Section 5, and is fixed against it with four iron stays or more fastened to the
cheeks (see 1, 1, Section 1 and 2).
:
Section 8. E, a spring catch, the top part with a flap c, with screws or
rivet holes to fix it to back frame N, the bottom end with a joint. The lower
part with the catch is fitted with joint d, at the other end an hinge joint e
fixed on the back frame. The end of the catch rests against it, with a hole
through the back frame for a poker or other instrument to touch an iron or
other pin fixed to the hinge on the back frame, which lifts up the spring
catch, and thereby lets fall the backs and bottom, as at E, Section 1.
The above is a particulur description of the whole of our Invention, and
which we conceive every competent workman must fully comprehend. But
we wish it to be understood that, when required, we omit the fire shades, and
that we apply the fire shades to register stoves now in common use. And
further, that although our Drawings describe only a register stove, yet our fire
securer or extinguisher is applicable to various other description of stoves.
In witness whereof, I, the said John Cowden, have hereunto set my
hand and seal, this Second day of April, in the year of our Lord One
thousand eight hundred and eight.
JOHN COWDEN. (L.S.)
