IMPROVEMENTS IN STOVES
Year: 1842

page_text: TO ALL TO WHOM THESE PRESENTS SHALL COME, I, THOMAS
WALKER, of Birmingham, in the County of Warwick, Stove Manufacturer,
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 Ninth day of August, in the sixth year of Her reign, did, for
Herself, Her heirs and successors, give and grant unto me, the said Thomas
Walker, Her especial licence, full power, sole privilege and authority, that I,
the said Thomas Walker, my exors, adiñiors, and assigns, or such others as.
I, the said Thomas Walker, my exors, admors, 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 "IMPROVEMENTS IN STOVES;" in which said Letters Patent is
contained a proviso that I, the said Thomas Walker, 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.

page_text: NOW KNOW YE, that in compliance with the said proviso, I, the said
Thomas Walker, do hereby declare that the nature of my said Invention, and
the manner in which the same is to be performed, are fully described and
ascertained in and by the following statement thercof, reference being had to
the Drawing hereunto annexed, and to the figures and letters marked thereon
(that is to say):-
DESCRIPTION OF THE DRAWING.
Figure 1 is a section of a stove having my improvements applied thereto.
A is an octagon base; in this base is the ash drawer B, with a regulator C.
E is the stove door; this door is either glazed with tale, or not. F is a cast
iron dish, which holds the fire. G, a moveable grate, which serves as a
bottom to the dish. H is a strong cast iron lining, which protects the outer
cylinder from getting overheated. On the stove (or furnace part of the stove)
are placed two cases or cylinders, which I call radiators, M and L, one within
the other, as will be seen on examining the Drawing. Into the space between
these two cylinders or radiators L, M, the smoke ascends to the upper part,
and then descends down a back internal flue M' to the chimney pipe O.
Within the inner radiator is placed the fuel reservoir or feeder K, K, K,
which being filled from the top with fuel keeps the fire under it uniformly
supplied, so long as there is any fuel in the feeder, this feeder being air-tight
at the top by means of its lid R being pressed into sand. The fuel in the
feeder cannot burn for want of atmospheric air, although it is placed perpen-
dicularly over the fire, but remains perfectly unignited until it sinks below the
feeder bottom, whereby I gain the desirable ends of keeping a fire permanently
supplied with fuel and one uniform heat. P is the inward passage, by means
of which cold air enters, to convey the heat from the internal radiator. Qis
the passage for the egress of the air thus warmed. T is the top or seat of the
lids or covers. U, U, are passages, more clearly shewn at Figure 2, to allow
of cleaning the soot from the inside of the stove, and these passages are covered
by the sand ring S, S.
.
Figure 3 shews a section of Figure 1, taken horizontally through the
lines b, 6; and I would remark that in some cases I apply a moveable bottom
to the feeder K, shewn in section and plan in Figure 3º. The object of this
is, that when the lower part of the feeder becomes burnt away a new portion
may be substituted.
Figure 4 represents a slight variation in the arrangement of this stove, the
only difference being that the internal cylinder or radiator is omitted.
Figure 5 represents a section through the dotted lines b, b, Figure 4.
Figures 6 and 7 represent an elevation in section, and also a plan in section,

page_text: of the lower part of another arrangement of stove having a corrigated fire pot
or dish a, a, as shewn, with a feeder K in the centre.
I would observe that these corrigations may extend the whole height of the
stove or only part thereof, as found most convenient, and sometimes I use an
external cylinder, as represented in dotted lines. This becomes necessary
when the fire pot only extends a portion of the height. These corrigations are
so made as to act as a series of vertical bars, to keep the fire together over the
centre grate b, and also to form recesses c, for the heat to escape into them
laterally from the fire, instead of passing through the body of ignited fuel,
and, at the same time, to increasing the quantity of external heating surface,
by forming chambers, as shewn in the Drawing at d. Figures 8 and 9 shew
another description of dish or fire pot, with solid vertical bars a, a.
Figures 10 & 11 shew a plan in section and an elevation, also in section, of
another description of stove. In this case the feeder serves the purpose of a
fire pot, having a series of slits or other openings z, z, to the height to which
it is desired the fuel should be consumed in the feeder.
e, e, are tubes for the
passage of the atmospheric air into and from the stove, in order that the same
may become heated.
I would remark that I do not confine myself to the shapes of the stoves or
the radiators herein shewn, provided the peculiar arrangement be retained.
But what I claim is, first, the mode of combining the feeder K, K, within
a case L, such feeder descending into a stove, as shewn and described in
respect to Figures 1, 2, 3, 4, & 5.
I also claim the combining a dish F, with inclined sides, with a feeding
trunk K, as described in respect to the same Figures. And I also claim the
mode of forming and closing the upper or top part of the stove T, which
receives the covers and ring, together with sand, as described in respect to the
same Figures. Secondly, I claim the mode of making a stove by employing
a corrigated fire pot, the angles of which constitute upright bars in continua-
tion of a feeder K, as described in respect to Figures 6 and 7. And I also
claim the mode of forming a fire pot, such as is shewn in Figures 8 and 9,
where the upright bars at the upper surface of the pot are solid. And, thirdly,
I claim the mode of making a feeder with slits or openings z, as described in
respect to Figures 10 and 11.
In witness whereof, I, the said Thomas Walker, have hereunto set my
hand and seal, this Ninth day of February, in the year of our Lord
One thousand eight hundred and forty-three.
THOMAS (L.s.) WALKER.
