Year: 1808

page_text: TO ALL TO WHOM THESE PRESENTS SHALL COME, I, JOHN
WARREN, of the Town and County of Poole, Stone Mason, send greeting.
WHEREAS His most Excellent Majesty King George the Third, by His
Letters Patent, under the Great Seal of Great Britain, bearing date at
Westminster, the Fifteenth day of September, in the forty-eighth year of His
reign, did, for Himself, His heirs and successors, give and grant unto me,
the said John Warren, His especial licence, that I, the said John Warren,
my executors, administrators, or assigns, or such others as I, the said John
Warren, 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 APPARATUS TO PREVENT CHIMNIES FROM SMOAKING, AND TO
EXTINGUISH FIRES IN GRATES AND STOVES, WITHOUT MAKING ANY DUST OR SMOAK IN-
JURIOUS TO THE ROOM OR FURNITURE;" in which said Letters Patent there is con-
tained a proviso obliging me, the said John Warren, by an instrument in
writing under my hand and seal, particularly to describe and ascertain the
nature of my said Invention, and in what manner the same is to be performed,
and to cause the same to be inrolled in His Majesty's High Court of Chancery
within one calendar month next and immediately after the date of the said
recited Letters Patent, as in and by the same, reference being thereunto had,
will more fully and at large appear.

page_text: NOW KNOW YE, that in compliance with the said proviso, I, the said
John Warren, do hereby declare that the nature of my said Invention, and
the manner in which the same is to be performed, is described and ascertained
in the plan hereunto annexed, and in the following explanation thereof, that is
to say
The apparatus has two objects: first, to cause a continual current of the smoak
until its exit in the air, and to disperse it without any return into the chimney;
and, second, to extinguish fires in grates and stoves without making any dust or
smoak injurious to the room or furniture. It consists of two parts:-1st, a frame
to be placed at the top of the chimney, which not only causes the smoak to
pass into the open air without any lodgement, but excludes the weather from
having any immediate access to the chimney. 24, a plate at the bottom of the
chimney to be fixed in a frame in the breast of the chimney, and to move in
grooves from the mantle to the hearth, and which by being let down in part
will greatly assist in preventing chimneies from smoaking, and by being let down
entirely will so exclude the current of air as to extinguish the fire in the grate
or stove, and will also materially assist in extinguishing fires in chimneys.
The capital or roman letters A, B, C, D, E, denote that part of the apparatus
which is to be fixed at the top of the chimney; it is to consist of a frame of
copper, tin, or other metal, and to have two retort flues, and four dispersing
flues, and the following, having reference to the plan hereto annexed, contain
the plans and elevations of the several parts of this part of the apparatus:
A, the plan, not to be less than nine inches diameter; A, N° 1, the elevation,
to be one and a half times in heighth the diameter of d°; B, the section or smoak
divider, is to be hung by two hinges, and to fall into the elevation A, N° 1, but
the upper part of it when it so falls in must be made to project over the out-
side, as plan B, N° 1, sufficient to keep the weather from getting inside of the
elevation A, N° 1, when the smoak divider is lifted up, which can be easily
done, the chimney sweeper can go on the outside and clean the flues with great
ease to himself. C, C, the plan of the throats, through the elevation of which
the smoak is to pass from the elevation A, N° 1, to the retort flues D, D
C, C, No 1, elevation of the throats.. The length of the throats from the
clevation A, N° 1, as described by the mark in the margin hereof, and the plan
hereunto annexed, may at any time be extended where requisite for the conve-
niency of fixing the frame. D, 1), the plan of the retort flues; D, N° 1, eleva-
tion of one of the retort flues, the other retort flue to have the same elevation ;
E, E, E, E, plan of the dispersing flues; E, E, N° 1, narrow elevation of d'
E, E, No 2, broad elevation of d°. The plan and elevation of A and A N°1 will
sometimes be a circular body, instead of square; to accord with the form of the

page_text: chimney flue, in which case the diameter may be more or less than nine inches
and it will require a circular cover, hung with one hinge, with a smoak divider,
as per section and plan B. Note: For the conveniency of fixing the frame, this
part of the apparatus, whether round or square, may be fixed in a funnell of
about two feet in length, and the funnel in that case is also to be of sufficient
length besides to fasten it on the chimney. The numbers from 1 to 18, and
the letters a, b, c, d,.e, f, g, h, i, k, l, denote the several parts of that part of the
apparatus which is to be fixed at the botton of the chimney; it may be made with
iron, brass, or any other hard metal.. The plate, as per Drawing, is to be made
conformable to the fire-place as to heighth and width, and must invariably be
two inches in heighth more than the heighth from the hearth to the under side
of the mantle, and must act in a perpendicular direction. No 1, the sliding
plate, fastened to the line or chain N° 11, and in the grooves Nos 5, 5; N° 2,
the sliding plate, without either line or chain or grooves; No 3, the section of
the plate, made with small wheels to prevent the edge of the plate.touching
the back of the grooves; N° 4, the section of the grooves in the frame on
which the plate is to act; N° 4°, the section of grooves to be made from the
frame to the hearth, and the part where dotted, which is the outer part of the
these grooves, to take off occasionally; N° 5, 5, front view of the grooves in
the frame; N° 6, plan of lower bar, through which the plate is to descend and
ascend; N° 7, thickness of lower bar; N° 8, plan of the top bar, with plan of
pullies; No 9, thickness of top bar; Nos 10, 10, 10, 10, four pullies, to act for
raising or lowering the plate, the two center ones with ears rivitted into the top
bar, the two outside ones with hooks and eyes, the eyes made.fast in the walo;
No 11, 11, 11, 11, the line or chain passing over the pullies; N° 12, 12, a
weight, nearly equal to the weight of the plate. Note: The frame at the bottom
of the chimney to be covered closely in front with a plate. N° 18, 18, small
chain and balls for raising and lowering the plate. Note: Where the form
of the chimney and room will admit of it, and it is desired, the line and
weights Nos 11 and 12, may be brought into the room, and serve to raise
and lower the plate, instead of the small chain and balls No. 13. A box
may be used for a weight with one pulley only to raise or lower the plate,
instead of the pullies before described, and is to be preferred whenever
convenient. a denotes the section of box; b, plan of box, fastened to the
top bar, with plan of ear and pulley; c, plan of top of box, with plan of
pulley detached from top bar; d, section of box sideways, with top and
bottom bar; e, side of do without the bar; f plan of d°; g back of box, with a
joint in two places in order to shift the upper and lower part, with two simple
fastenings marked h, h, where the upper shifting part cannot be easily got at;

page_text: otherwise there may be a small door made for that purpose in the front of the
chimney opposite the upper shifting part; i, the plan of the bottom of the box;
k, the line or chain; 1, the weight, nearly equal to the weight of the plate. Note:
There must be a groove in the hearth stone for the plate to fall into a quarter
of an inch deep; the top bar of the grate or stove must be not less than one
inch and a half from the plate when lowered. The lower bar 6, 7, of the
apparatus above described to be fixed nearly lovel with the under side of the
mantle, and also if convenient a recess to be left in the brickwork of one
inch and a half, in order that the front of the apparatus may lino with the face
of the brickwork. There may be a half plate merely for preventing the smoak,
but not for extinguishing the fire, to have four wheels, and work in a frame, as
before described, 5, 5, 7, 9, to act either with or without weight or pullies, but
if without, there must be two springs, one on each edge, near the top, as per
section marked thus a; this half plate may be made of tin. y, front view of
half plate.
In witness whereof, I, the said John Warren, have hereunto set my hand
and seal, this Fifth day of October, in the year of our Lord One
thousand cight hundred and eight.
Inrolled the Sixth day of October, in the year above written.
