of 5 Southampton Buildings in the County of Middlesex Patent Agents for
an invention of "A NEW OR IMPROVED STOVE."-A communication from
abroad by Leopold Bregha, of Dresden, Saxony.
PROVISIONAL SPECIFICATION left by the said Alexander Browne at the
Office of the Commissioners of Patents on the 12th April 1882.

Buildings in the County of Middlesex Patent Agents "A NEW OR IMPROVED
(a communication from abroad by Leopold Bregha of Dresden, Saxony).
STOVE
The object of this invention is the construction of a stove by which the warmth
derived from the materials of combustion is thoroughly utilized and the atmosphere
speedily warmed.
The stove consists of three cylindrical chambers placed one within the other.
The two inner chambers are in communication with each other for the passage
of the heated gases from the fire. The annular space between them being divided
by a partition extending nearly to the bottom. The outer casing is separated
from the inner casings and is used for heating the air which enters the apartment
or building.
The furnace consists of a grate formed of cross bars arranged in steps diagonally
and also of another grate at the bottom of said diagonal grate formed of horizontal
bars as usual. Upon the stepped bars small coal is fed through an opening above
and the gases generated from this small coal pass over the lower grate upon which
lics coke in an incondescent condition, where they become mixed with atmospheric
air and are set in a state of complete combustion.
The gases of combustion then rise into the innermost cylinder and through an
opening into one half of the inner annular space formed by the inner and the
intermediate cylinders and descending to the bottom of this space pass under an
Pine RAI

page_text: opening left by the partition in the inner annular space and rise up the other half
of the inner annular space and through an opening into the chimney.
The air to be heated is taken in at the lower part of the outer annular space
formed by the intermediate and outer cylinders and is taken by pipes through the
inner annular space before described being there surrounded by tho products of
combustion and into the upper part of the outer annular space and then passes
over a water reservoir placed in cach outlet. This water water reservoir is heated
by the heated air in the outer annular space so that the water it contains is
evaporated and carried off by the heated air which then passes into the room or
building to be heated.
A water gauge is attached to each reservoir and slides are arranged so as to
regulate the degree of moisture which it is desired to give the heated air.

atmospheric air and are set in a state of complete combustion.
The gases of combustion then rise into the innermost cylinder and through an
opening into one half of the inner annular space formed by the inner and the

DESCRIPTION OF THE DRAWING.
In the accompanying drawing fig. 1 shews a longitudinal section on the line A, B,
in fig. 2 of a stove constructed according to my said invention. Fig. 2 is a
transverse section of the same and fig. 3 is a vertical section on the line C, D,
Fig. 4 is a plan of the stove without the covering piece. Fig. 5 is an elevation of
the door The cold air enters through the lateral passages a a into the exterior
shell M. The entrance of such air is regulated by valves in the usual way. The
cold air then passes out of the lower part of the shell M into the tubes b which
lead through the interior shell N then rises up within it into the fire space passes
through the covering piece n of the interior shell N and thus into the upper part
of the exterior shell M. The air which has been heated on its passage through the
tubes bis then conducted over the water reservoir c. Each outlet & has a metallic

page_text: water reservoir of its own which is arranged in the manner represented and is
heated by the exterior shell M so that the water can easily evaporate and be
carried by the hot air which streams over it into the space which it is desired to
warm. A water gauge is attached to each reservoir and slides of the ordinary
description are arranged so as to regulate the degree of moisture which it is desirod
to give the heated air.
The fire place consists of a grate with steps R on which small coal is placed in
order to generate the gases required. The gases pass over the horizontal grate-
bara P on which lies coke in an incandescent condition, where they become mixed
with atmospheric air and are set in a state of combustion.
The gases of combustion then mount upwards in the central cylinder O, pass
through the aperture o in the upper part into the ring shaped cylinder formed by
the cylinder and the interior shell N where they are compelled by a partition n³.
(which extends from the covering piece n nearly to the bottom of the shell N) to
pass in a downward direction and make their way into the part lying on the other
side of n. whence they escape through the pipe d into the chimney. On their
passage the hot gases of combustion surround the tubes b and thus heat the atmo-
spheric air which comes within the sphere of their action. For the purpose of
excluding any possibility of damp, it is advisable to form the outlet passages b of
glazed clay.
The construction described above offers through its thorough utilization of the
heat derived from the materials of combustion, essential advantages as compared
with the methods hitherto in use.
Having thus described the unture and object of the said invention and the
means whereby the samo may be carried into practical effect I would remark in
conclusion that what I claim as the invention communicated to mo from abroad
and desire to secure by the hereinbefore in part recited Letters Patent is a stove
constructed substantially as set forth.
In Witness whereof I the said Alexander Browno have hereunto set my hand
and seal this twenty soventh day of October in the year of our Lord
one thousand eight hundred and eighty two.
