IMPROVEMENTS IN STOVES
Year: 1885

page_text: I ALFRED JULIUS BOULT of 323. High Holborn in the county of Middlesex,
Engineer do hereby declare the nature of the said invention for " IMPROVEMENTS
IN STOVES (a communication from Karl Lerch and Karl Seidl of Graz, Austria)
to be as follows:-
دو
This invention relates to improvements in closed stoves and has for its object an
improved arrangement of internal flues in which the hot gases circulate; the stove
is moreover provided with a suitable number (say from two to twelve) of tubes or
pipes say of clay or iron which are surrounded by the hot gases and admit the air
of the apartment in which the stove is placed.
There is a space or chamber filled with fuel the gases developed therein pass
through suitable apertures into upwardly extending channels or flues.
The gases
next pass through openings into and along a descending channel or flue whence the
gases flow into another rising flue which leads the same to the chimney or a flue
connected therewith.
The air-tubes hereinabove referred to may be of clay pottery ware or cast iron
they are set vertically in the flues and continually surrounded and heated by the
hot gases. These tubes draw in the air from the apartment in which the stove is
set by horizontal passages and allow it to escape by suitable openings at the top
or in the lid of the stove.
Each stove has two doors which close hermetically the upper one serves for the
introduction of the fuel the lower one closes the ash-pan or ash-pit as usual.
A movable grating is supported on the frame and allows the fire place to be
readily cleaned.
For heating large rooms the air may be led into the horizontal air-passages from
outside and the lower part of these passages being surrounded by the flames; this
air will be rapidly heated.
This stove requires to be filled once only in 24 hours.

do hereby declare the nature of this invention (a communication from Karl
Lerch and Karl Seidl of Graz, Austria) and in what manner the same is to be
performed, to be particularly described and ascertained in and by the following
statement:
This invention relates to improvements in closed stoves and has for its object an
improved arrangement of internal flues in which the hot gases circulate, the stove
is moreover provided with a suitable number (say from two to twelve) of tubes or
pipes say of clay or iron which are surrounded by the hot gases and admit the air
of the apartment in which the stove is placed.
This invention is represented in the accompanying drawings in which
Figure 1 is a section on line Y Y of Figure 2.
Figure 2 is a section on line Z Z of Figure 1.
Figure 3 is a horizontal section on xx Figure 2.
Figure 4 is a transverse section of the grate and its supporting slide..
There is a space or chamber a filled with fuel the gases developed therein pass
through suitable apertures c c¹ and in the direction of the arrows 1. 1ª into upwardly
extending channels or flues b 61. The gases following the path shown by the
arrows 2. 2ª, next pass through openings g g into and along a descending channel
or flue whence (following the path shown by the arrow 3) the gases How into
another rising flue f¹ which leads the same to the chimney or a flue (h) connected
therewith.
The air tubes hereinabove referred to may be of clay, potteryware or cast iron.
they are set vertically in the flues and continually surrounded and heated by the
hot gases.
These tubes kk¹ k² k³ draw in the air from the apartment in which the
stove is set by horizontal passages (in the direction of the arrows 5) and allow it to
escape by suitable openings at the top or in the lid of the stove.
Each stove has two doors which close hermetically the upper one m serves for
the introduction of the fuel the lower one n closes the ash-pan or ash-pit as usual.
A moveable grating i is supported on the frame 7 (Figure 5 & 7) and allows the
fire place to be readily cleaned.
For heating large rooms the air may be led into the horizontal air-passages k k
kk³ from outside and the lower part of these passages being surrounded by the
flames, this air will be rapidly heated.
This stove requires to be filled once only in 24 hours.
Having now particularly described and ascertained the nature of the said
invention and in what manner the same is to be performed as communicated to
me by my foreign correspondent I declare that what I claim is
1. In a stove the combination with the ascending flues b b¹ of the air tubes k k¹
² ka located therein substantially as specified.
2. In a stove the combination therewith of the partitions e e¹ which divide the
interior into two ascending flues b b¹ and one descending flue f substantially as
specified.

page_text: 3. In a stove the combination therewith and with the partitions e e¹ of the
partition which separates the descending flue f from the ascending flue f¹
substantially as specified.
4. In a stove the combination therewith of the air tubes kkkk³ which take
in the air of the room at their lower ends and deliver the same from their upper
ends thereby promoting the circulation of the air of the room substantially as
specified.
5. In a stove the combination therewith of the sliding grate bars i substantially
as specified.
