IMPROVEMENTS IN STOVES
Year: 1838

page_text: WATSON'S SPECIFICATION.
TO ALL TO WHOM I, THOMAS WATSON, of Addle Hill, Doctors Com-
mons, in the City of London, Mechanic, 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 Tenth day of April, in the second year of Her reign, did, for Her-
self, Her heirs and successors, give and grant unto me, the said Thomas Watson,
Her especial licence, full power, sole privilege and authority, that I, the said
Thomas Watson, my exors, adiñiors, and assigns, or such others as I, the said
Thomas Watson, my exors, adiñiors, 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 night make, use, exercise, and vend,
within England, Wales, and the Town of Berwick upon Tweed, my Invention
of "IMPROVEMENTS IN STOVES;" in which said Letters Patent is contained a
proviso that I, the said Thomas Watson, shall 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 six
calendar months next and immediately after the date of the said in part recited
Letters Patent, as in and by the same, reference being thereunto had, will more
fully and at largo appear.
NOW KNOW YE, that in compliance with the said proviso, I, the said
Thomas Watson, do hereby declare the nature of my said Invention, and the
manner in which the same is to be performed, are fully described and ascer-
tained in and by the following statement thereof, reference being had to the

page_text: Drawing hereunto annexed and to the figures and letters marked thereon, that
is to say:-
My Invention relates to stoves for heating rooms, halls, and other places.
DESCRIPTION OF THE DRAWING.
Figure 1 represents a front view of a stove constructed according to my
Invention. Figure 2 is a side view thereof. Figure 3 is a front section.
Figure 4, a side section; and Figures 5, 6, 7, and 8, are separate views of
some of the parts. In each of these Figures the same letters indicate similar
parts. a, a, is the external casing of iron, the nature of which is clearly shown
in the various Figures of the Drawing. bis the flue, which is what is called
a descending flue, but other flues may be applied. The interior of the stove is
divided into two parts or compartments by means of fire brick, c being the com-
partment for fuel, and d the compartment or passage for the smoke and draft, the
ignited portion of the fuel not rising much above the point e, the fuel which is con-
tained in the compartment c being for for a continued supply, which progressively
descends as that which is ignited consumes; thus is a constant supply kept up
for many hours. 9 are the fire bars or grate; they consist of a series of bars
cast in a quadrangular frame, which is supported by the projections or guides f,f
which allow of the grate g having a slight horizontal movement, in order to shake
the same, with a view to cause the ashes to fall between the bars; and for this
purpose there are projections or teeth formed on the under surface of the grate.
At h, h, and i, is an axis having teeth or projections, which, taking into the teeth
on the under part of the grate, will move the grate to and fro, when desired, by
causing the axis i to turn first in one direction, then in another, by means of a key
to fit the outer end of the axis i, as will readily be understood by examining
the Drawing. j is the ash-pit or drawer by which the ashes are removed; and
the draft below the fire bars or grate g may be regulated by forcing the drawer j
in closely or leaving the same partly open, which, however, is common to such
description of stoves or grates, they requiring but a small supply of air. k, k,
is a lining of fire brick. 1, 1, are the front fire-bars, which are flat, but set to
incline inwards, with a view to cause the ashes to fall inwards to prevent a dust
in the room or place where the stove may be placed, particularly when the door m
is opened by being raised from off the bearings n to the bearings o, which may
readily be done when it is desired to use the fire as an open fire. The door m
may have talc let in between each division, similar to many stoves now in use,
or the door may be a close door of iron. p is the door by which a supply of
fuel is placed in the compartment c; and it will be seen that in opening this
door the swing door 9 will be operied to the flue. The object of so opening a

page_text: way into the flue when a supply of fuel is being placed in the chamber.c is
that it often happens that there is more or less smoke in the upper part of the
chamber c, which, on opening the door p, flows out into the room; but this is
prevented by opening a way into the flue. The mode of opening such swing
door 9 is as follows:-to the projection r is attached the connecting rod s, which
is attached to the arm t on the axis of the door q, as is shewn in the Drawing.
v is a sliding bolt to retain the door closed; and wis a spring constantly keeping
the bolt up.
Having thus described the nature of my Invention and the manner of com-
bining the parts, I would remark, that for the most part the arrangement of the
stove is similar to what have heretofore been made. I do not, therefore, make
any claim to the stove so far as it is like those of former constructions. And
I would further remark, that variations may be made in the shape of the same
without departing from my Invention, which I would have it understood consists:
First, in the mode of applying a moveable grate g, as herein described. Secondly,
in the mode of applying the swing door q to open when a charge of fuel is being
applied, as above described.
In witness whereof, I, the said Thomas Watson, have hereunto set my
hand and seal, this Tenth day of October, One thousand eight hundred
THOMAS (L.S.) WATSON.
AND BE IT REMEMBERED, that on the Tenth day of October, in the
year of our Lord 1888, the aforesaid Thomas Watson came before our said Lady
the Queen in Her Chancery, and acknowledged the Specification aforesaid, and
all and every thing therein contained and specified, in form above written. And
also the Specification aforesaid was stamped according to the tenor of the Statute
made for that purpose.
