AN IMPROVED STOVE
Year: 1842

page_text: TO ALL TO WHOM THESE PRESENTS SHALL COME, I, WILLIAM
POPE, of the Edgeware Road, in the County of Middlesex, Ironmonger, 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 Sixth day of December, in the sixth year of Her reign, did, for
Herself, Her heirs and successors, give and grant unto me, the said William
Pope, my exors, adiñors, and assigns, Her especial licence, full power, solo
privilege and authority, that I, the said William Pope, my exors, adñiors, and
assigns, and such others as I, the said William Pope, my exors, adñors, or
assigns, should at any time agree with, and no others, from time to time and
at all times thereafter during the term of years therein expressed, should
and lawfully might make, usc, exercise, and vend, within that part of Her
said Majesty's United Kingdom of Great Britain and Ireland called England,
Her Dominion of Wales, and the Town of Berwick upon Tweed, my Inven-
tion of "AN IMPROVED STOVE;" in which said Letters Patent there is contained
a proviso that I, the said William Pope, shall cause a particular description
of the nature of my said Invention, and the manner in which the same is to
be performed, under my hand and seal, 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 pursuance of the said proviso, I, the said William
Pope, do hereby declare that the nature of the said Invention, and the
manner in which the same is to be performed, are fully described in and by

page_text: the following Specification thereof, reference being had to the Drawings here-
unto annexed, that is to say:-
Figure 1 of the said Drawings represents an external elevation of my im-
proved stove; Figure 2, a vertical section thereof from side to side; Figure 3,
a vertical section thereof from front to back; Figure 4, a plan in the lines a, b;
and Figure 5, a plan in the line c, d. The stove is of a circular form; A is
the external case, B the foundation plate, which are rivetted to the orna-
mental feet ff; and C, the top plate or cover; D, D, are vertical pipes open
at top and bottom, which are fixed air-tight into corresponding orifices in the
plates B and C, and may be of any convenient number, as four, six, eight, or
more; E, is a box, which serves the double purpose of an air feeder to the
fire box (afterwards mentioned), and a receptacle for the ashes resulting from
combustion; it rests on trivets g¹, g', which project upwards from the founda-
tion plate B, to the height of about an inch and a half; F is the passage way
into the box E (the two parts being cast together in one piece), being closed
at the mouth with an air-tight door through G, which a chamber H, is passed
with a screw on its spindle, by the unscrewing of which more or less a greater
or less quantity of atmospheric air can be admitted into the interior. The
door G is made to be raised up, when required, to remove the ashes that collect
in the bottom of the box E; I, is the fire grating, which rests in a recess in
the top of the box E; K is a fire box, which is placed on the grating, and has a
number of open vertical spaces 9, 9, on one side near to the top, through which
the
gaseous products of combustion may escape; L is a funnel for the supply of
fuel to the fire box, which fits at bottom into a recess in the top of the fire box
K, and passes out at top through the cover C, with which it is made to form
an air-tight joint. M is the lid of the funnel L, which is made to lift off and
on, and to fit the funnel head very accurately, in order that none of the pro-
ducts of combustion may escape in that direction, and also that it may not give
admission to any atmospheric air after the fire box has been charged with fuel
and the fire lighted. N is the flue which leads to the chimney, and is placed
on the side of the stove opposite to that where the open vertical spaces g, g,
are left in the fire. box. O is annular reservoir for water placed on the top
of plate C, from which. water is conveyed by the capillary attraction of a
number of cotton or other fibrous threads into the vertical pipes D, D, where
it is evaporated, and serves to moisten the ascending columns of warm air.
P is an ornamental top piece or dome affixed to the top of the funnel lid M.
From the preceding description, it will be seen that the parts of the stove
where the fire is made, and through which the gaseous products of combustion
pass towards the chimney, are entirely closed up and separated from the atmo-

page_text: sphere of the chamber or apartment in which the stove is placed, and that the
only thing therefore that can be given out from the stove to that atmosphere is
a portion more or less of the heat produced free from any deleterious mixture
whatever. The gaseous products of combustion, after issuing from the fire
box K through the open vertical spaces g, g, make their way in the various
directions indicated by the arrows in the plans, Figures 6, 7, and 9, to the
chimney, filling the case A, and circling around the pipes E, E, giving out
their heat to the surrounding atmosphere, partly through the side of the case
A, and partly through the columns of fresh air which are continually ascending
in the pipes and passing out from them; the rarification of each column causing
the ascent of that which follows. The supply of atmospherie air which is
required to support combustion within the fire box being admitted only through
the small orifice in the door G, and under the control of the rod H, the
superior pressure of the external atmosphere prevents the possibility of any
deleterious gases being driven back in that direction. The water again which
is evaporated through the medium of the capillary conductors h, h, serves to
prevent that excessive dryness which stoves, as ordinarily constructed, impart to
the air of the apartments in which they are fixed. Instead of the ascending
air pipes D, D, being of a circular form, they may be of the form of a section
of a circle, as represented in the plan, Figure 6, or of any other equally
efficient form. Or such pipes may be altogether dispensed with, and the stove
constructed in the manner represented in the plan, Figure 7, and sectional
elevation, Figure 8. Here A is an outer case, and B an inner one, concentric
to the other, connected together by a few cross pieces x, x, leaving a free
space 8, 8, between them open both at top and bottom, up which a
current of air will begin to flow continuously as soon as the stove is
heated, in the same way as when pipes are employed, though with less
rapidity.
The best situation for the vertical openings in the fire box.
for the escape of the gaseous products of combustion is, in this form
of stove, immediately over the mouth of the air feeder and ash box E, whence:
they are conveyed through the circular channel T to the chimney flue N. In
all other respects this stove is the same as that first before described. The
chimney piece is an all the preceding forms of stoves placed on the side
opposite to the vertical openings in the fire box, but it may be desirable to
cause the gaseous products of combustion to take a more circuitous course
to the chimney, in order that they may be more completely exhausted of their
eat before escaping into the external air; and for this purpose I place the said
ertical openings nearly fronting the chimney flue, as represented in the plan,
Figure 9, but with a vertical partition V inserted between the outer case and

page_text: the fire box and funnel, from top to bottom, in order that the gascous
column may be compelled to make the entire circuit of the stove before it is
exhausted.
And having now described my said Invention and the manner in which the
same is to be performed, I declare that though I have described my improved
stove as being of a circular form, and prefer that form, yet that the form may
be varied to suit taste and convenience, without any material departure from
the principle on which the same is constructed. And I declare also that
though I prefer making the stove entirely of iron, yet that the pipes D, D, may
be made of earthenware glazed on the inside, or of any other suitable material
that will bear and transmit heat well.
And I declare that what I claim is the improved stove first before described,
in the general combination of parts of which the same consists, and in the
various modifications thereof before pointed out or of which the same is
susceptible, whereby the products of combustion are prevented from parting
with anything but their heat to the surrounding atmosphere, and a current or
currents of air are caused to ascend continuously through the stove from the
surrounding atmosphere without intermingling with any of the said products
of combustion, the heat only excepted, and the air of the surrounding atmo-
sphere is kept in a humid state to the extent of the aqueous evaporation
therein provided for.
