PROVISIONAL SPECIFICATION left by the said Francis Wirth at the
Office of the Commissioners of Patents, with his Petition, on the
25th January 1868.
I, FRANCIS WIRTH, of the Firm of Wirth & Company, Patent Agents,
Frankfort-on-Maine (Germany), do hereby declare the nature of the
said Invention for AN IMPROVED APPARATUS FOR HEATING, EVAPORATING,
AND DECOMPOSING WATER, OIL, AND OTHER SUBSTANCES," a communication, to
he as follows:-
The said apparatus is constructed to heat, evaporate, and decompose
water, oil,and other substances, and to heat air and other gaseous bodies.
The said apparatus consists of one or more peculiarly constructed

metallic walls. These walls are of such a form that they absorbe the
heat and transmit it rapidly to the substances which are to be heated,
evaporated, or decomposed. The middle web or body of such metallic
walls is wedge-shaped in its cross section, the front surface of the
same being toward the fire-place. The sides of the metallic wall are
channeled. The divisions of the side surfaces which form the chan-
neling are made taper or wedge-shaped towards the exterior.
middle web or body has horizontal canals, and is strengthened at the
points where the canals are formed. These interior canals are nearer
together towards the fire-box than towards the smoke box. The increased
distance between these canals towards the top of the apparatus is propor-
tional to the diminishing force of the flame. By the combination of some
of these metallic walls vertical canals are formed, which are smaller at
the end towards the fire-box than at the top of the apparatus, and which
lead the smoke and other products of combustion through the apparatus
to the top or smoke box. The metallic walls can be put in com-
munication by means of cocks, one cock regulates the inlet of the
substances to be heated, evaporated, or decomposed, and another cock
regulates the outlet of the same. The interior horizontal canals are
connected externally and vertically by pieces which may also serve for
connecting the canals horizontally. The cross section of the metallic
walls towards the fire-place being larger than such section towards the
top the said walls are heated uniformly by the flame from the fire-place.
The capacity of uniform cooling from the interior to the exterior is
effected by the different distances between the canals of the metallic
walls I therefore obtain a large heating surface, and the accumulation
of soot and ashes is prevented. The substances to be heated are
introduced through the cocks to the interior horizontal canals, and the
heat is introduced from the outside of the metallic walls.
By thus
constructing the metallic walls the heat is almost entirely absorbed,
so that the temperature of the products of combustion at the orifice
of the chimney is very low. This absorbed heat is transmitted to the
substances to be heated with a rapidity adequate to the conducting
capacity of the metal of which the wall is made. The said substances
are therefore either heated, evaporated, or decomposed according to the
heat produced, and according to the quantity which passes the canals.

filed by the said Francis Wirth in the Great Seal Patent Office
on the 24th July 1868.
TO ALL TO WHOM THESE PRESENTS SHALL COME. I, FRANCIS
WIRTH, of the Firm of Wirth & Company, Patent Agents, Frankfort-
on-Maine (Germany), send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her
Letters Patent, bearing date the Twenty-fifth day of January, in the
year of our Lord One thousand eight hundred and sixty-eight, in the
thirty-first year of Her reign, did, for Herself, Her heirs and successors,
give and grant unto me, the said Francis Wirth, Her special licence that
I, the said Francis Wirth, my executors, administrators, and assigns, or
such others as I, the said Francis Wirth, my executors, administrators,
and assigns, should at any time agree with, and no others, from time
to time and at all times thereafter during the term therein expressed,
should and lawfully might make, use, exercise, and vend, within the
United Kingdom of Great Britain and Ireland, the Channel Islands,
and Isle of Man, an Invention of "AN IMPROVED APPARATUS FOR
HEATING, EVAPORATING, AND DECOMPOSING WATER, OIL. AND OTHER SUB-
STANCES,"
upon the condition (amongst others) that I, the said Francis
Wirth, my executors or administrators, by an instrument in writing
under my, or their, or one of their hands and seals, should particularly
describe and ascertain the nature of the said Invention and in what
manner the same was to be performed, and cause the same to be
filed in the Great Seal Patent Office within six calendar months next
and immediately after the date of the said Letters Patent.
NOW KNOW YE, that I, the said Francis Wirth, do hereby declare
the nature of the said Invention, and in what manner the same is to
be performed, to be particularly described and ascertained in and by
the following statement, reference being had to the accompanying Sheet
of Drawings forming a part of this Specification:-
The said apparatus is constructed to heat, evaporate, and decompose
water, oil, and other substances, and to heat air and other gaseous bodies.
The said apparatus consists of one or more peculiarly constructed
metallic walls. These walls are of such a form that they absorb the
heat and transmit it rapidly to the substances which are to be heated,
evaporated, or decomposed.

page_text: Figures 1, 2, and 3 are front, side, and back elevations of my improved
metallic wall; Figures 4, 5, and 6 are sections of the same; Figure 7
is a front elevation, showing a combination of four metallic walls with
a common fire-grate, drawn to a reduced scale; Figures 8 and 9 are
sections of the same; Figure 10 is a section on the line g-, Figure 8.
The middle web or body A of the metallic wall B is wedge-shaped in
its cross section, as seen in Figure 4, the front surface of the same being
towards the fire-grate. The sides of the metallic wall B are channelled,
as seen in Figure 6. The divisions of the side surfaces which form
the channeling are made taper or wedge-shaped towards the exterior.
The middle web or body A has horizontal canals a', and is strengthened
at the points where the canals are formed. These interior canals are
closer together towards the fire-box or grate C than toward the smoke
box D. The increased distance between these canals a¹ towards the top
of the apparatus is proportional to the diminishing force of the flame.
By the construction of some of the metallic walls B vertical channels a
are formed, which are smaller at the end towards the fire-box C than at
the top of the apparatus, and which lead the smoke and other products
of combustion through the apparatus to the top or smoke box D. The
metallic walls B can be put in communication by means of cocks b
and c, as arranged in Figures 5 and 7. One cock b regulates the inlet
of the substances to be heated, evaporated, or decomposed, and another
cock c regulates the outlet of the same. The interior horizontal canals a'
are connected externally and vertically by pieces . which may also
serve for connecting the said canals horizontally. The cross section of
the metallic walls B towards the fire-place C being larger than such
section towards the top; the said walls are heated uniformly by the
flame from the fire-place. The capacity of uniform cooling from the
interior to the exterior is effected by the different distances between the
canals a' of the metallic walls; I therefore obtain a large heating surface.
The accumulation of soot and ashes is prevented. The substances
to be heated are introduced through the cocks b and c to the interior
horizontal canals a', and the heat is communicated from the outside
of the metallic walls B. By thus constructing the metallic walls the
heat is almost entirely absorbed, so that the temperature of the products
of combustion at the orifice of the chimney is very low. This absorbed

page_text: heat is transmitted to the substances to be heated with a rapidity
adequate to the conducting capacity of the metal of which the wall
is made. The said substances are therefore either heated, evaporated,
or decomposed according to the heat produced, and according to the
quantity which passes the canals.
Having thus fully described the said Invention, and shown how the
same may be conveniently and advantageously carried into practice,
I claim
First. The exterior form of the metallic walls B, substantially as
set forth.
Second. The metallic wall B formed with interior canals a' constructed
and arranged substantially as described.
In witness whereof, I. the said Francis Wirth, have hereunto set
my hand and seal, this Seventeenth day of July, in the year of
our Lord One thousand eight hundred and sixty-eight.
FRANCIS WIRTH. (L.S.)
