CERTAIN IMPROVEMENTS IN STOVES AND FURNACES
Year: 1839

page_text: TO ALL TO WHOM THESE PRESENTS SHALL COME, I, HENRY
VENNER COCKS, of Birmingham, in the County of Warwick, Iron Founder,
send greeting.
WHEREAS Her present most Excellent Majesty Queen Victoria, by Her
Letters Patent under the Great Seal of Great Britain, bearing date at
Westminster, the Second day of November, in the third year of Her reign,
did, for Herself, Her heirs and successors, give and grant unto me, the said
Henry Venner Cocks, Her especial licence, full power, sole privilege and
authority, that I, the said Henry Venner Cocks, my exors, adññiors, and assigns,
or such others as I, the said Henry Venner Cocks, my exors, adñiors, 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 "CERTAIN IMPROVEMENTS IN STOVES AND
FURNACES;" in which said Letters Patent is contained a proviso that I, the said
Henry Venner Cocks, shall cause a particular description of the nature of my
said Invention, and in what manner the same is to be performed, 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
large appear.
NOW KNOW YE, that in compliance with the said proviso, I, the said
Henry Venner Cocks, do hereby declare the nature of my Invention, and the
manner in which the same is to be performed, are particularly described and
ascertained in and by the following description thereof, reference being had to
the Drawings hereunto annexed, and to the figures and letters marked thereon,
that is to say-

page_text: My Invention consists chiefly of improvements in that particular class of
stoves usually denominated close stoves; and although mine partake of that
general definition, yet one of my improvements is designed to produce a
ventilation or changing of the air of the apartment, and thus convert in effect
a close stove into an open one, thereby obviating entirely the complaint often
made of close stoves causing the air of the apartment in which they are placed
to become vitiated. In the annexed sheet of Drawings I have given examples
of four stoves, containing one or more of my several improvements, whereof
Figure 1 represents an external elevation, Figure 2 a vertical section, and
Figure 3 a plan of one of my patent stoves of the simplest construction. At a
is the fire chamber, having a grating at the bottom which extends over the
whole interior area of the stove, except that occupied by the cylinder g; at b
is a door for supplying the fuel, and at c is the ash pit, having the same extent
of area as the grate; it is provided with a door at d, which may be occasionally
wanted to admit of a large body of air, in the centre of which is a small
circular door e for regulating the admission of air to the fuel under combustion.
The smoke, flame, and heated gases arising from the ignited fuel first ascending
towards are immediately directed thence horizontally around the warm air
circulator g, and passing by the annular portion h (of the chamber f) enter
the smoke flue or chimney i, which is provided with a throat valve or damperj
The warm air circulator g, as represented in the Drawing, is open both at
the bottom and the top; the cold air entering at the bottom, and continually
ascending by the rarifying heat of the stove, necessarily produces a continual
current of air upwards, which being warmed in its progress, difluses itself
throughout the apartment. What I claim as original and of my invention in
this stove is, first, the fixing the warm air circulators and the fire chamber in
one single case or compartment k, k, so that the larger circumference of the
said warm air circulators shall be inclosed in one chamber of hot air. The
stove which I shall next specify is of the kind just described, though it is of a
different shape, and is provided with two warm air circulators instead of one.
Figure 4 represents a front elevation of it; Figure 5, a vertical section made
in the direction of the dotted line 7, 1, on the plan which is marked Figure 6.
The letters of reference marked in these Figures being the same as in the last
where the parts correspond, renders further explanation almost superfluous;
but I will briefly state that at a, a, a, is the fire chamber and grating; b, the
fuel door; c, the ash chamber; d, its door, having in its centre an air door; e, the
flames and heated matters, taking the same course as in last instance around
the warm air circulators and into the smoke flue or chimney 7. The claim to
invention in this stove is the same as that mentioned in the last, and I have
inserted it in my Specification, not only to shew an elegant modification of my

page_text: improved stoves, but to illustrate in the simplest manner my mode oficon-
structing them with more warm air circulators than one, my claim extending
to any number of them; whether they be vertical, horizontal, inclined, zigzag,
strait, or curved. Another modification of the last-mentioned, stove is
exhibited in Figures..7, 8, and 9, whereof Figure 7 is an elevation; 8, an
irregular figure, shewing two sections, one through, the dotted line 4, 7, and the
other through the dotted linen, 11, marked on the plan, Figure 9., The
difference between this stove and those previously described, consists in
restricting the place for fire a to the front portion of the stove, which in most
cases will be found adequate to the generation of suflicient heat to warm the
apartment wherein it may be placed? My claims to invention in this stove
differs in no respect from those already specified. Figures 10, 11, and 12,
exhibit an elevation, section, and plan illustrative of a stove which combines the
properties of the preceding together with my new ventilating apparatus. At a
is the fire-place; b, the fuel door; c, the ash pit; d, ash pit door; and e, the air
valve. The flames and heated matters first ascending towards f, take then a
horizontal direction around the warm air circulator g through annulas / into
the chimney i. At o is my ventilating pipe, provided at the bottom with a
dise valve, that turns upon a pin at p, so as to enlarge or diminish the openining
into the pipe, and permit the air of the apartment to ascend it, and be changed
in any desired quantity by its escaping into the chimney i (in the same way
as it does in a common open stove or fire-place) whenever desired. My claim
to invention in this stove consists, first, in fixing the warın air circulators in
the same chamber or external case k, k, that contains the fuel, whatever may
be the number or form of the said warm air circulators, and whatever may be
the shape of the said external casing, but so that the said warm air circulator
or circulators may be surrounded by hot air within one single chamber; and,
second, I claim the apparatus and method described for producing ventilation;
and although I have given but one example or mode of carrying this part of
my Invention into execution, I desire it to be distinctly understood that the
pipe for conducting the air of the apartment through the stove into the chim-
ney may be differently posited, with the same or nearly the same advantages,
and that such variations come within the scope of my patent right.
In witness whereof, I, the said Henry Venner Cocks, have hereunto set
my hand and seal, this Twenty-third day of April, in the year of our
Lord One thousand eight hundred and forty.
HENRY VENNER (L.s.) COCKS.
