Improvements in the Construction and Manufacture of Pottery-ware
Domestic Stoves for Heating Purposes.
I JULIUS SALOMON of 7 Prasidentenstrasse, Berlin, Prussia, Manufacturer, do
hereby declare the nature of this invention and in what manner the same is to be
performed, to be particularly described and ascertained, in and by the following
statement :---
Pottery-ware stoves as now constructed have the shell entirely open inside
thereby causing a large amount of the heat to pass out at once to the chimney and
lost for heating purposes; but according to this invention the interior of the stove
is formed in a number of vertical passages for the path of the heat before passing
to the chimney, which gives better heating results. These passages communicate
with each other in such a manner as to cause the heat to travel upwards and down-
wards, and they may be made in one with the rest of the stove, or they may be
made separately and fitted in. The shell of the stove may have vertical narrow
passages through from bottom to top for air to pass through to be heated and so
causing a large quantity of heated air to pass into the room where the stove is
standing. Stoves as above described have the shell formed in one or more pieces
preferably two, by expression of the plastic material of which they are made
through dies in a manner similar to drain-pipes. A. stove so constructed if
made in two pieces may have the parts to fit together; or the two parts may be
baked together to form one.
After the clay is first expressed into the desired form it is partially dried, when
the necessary openings for door of fireplace, ashpan, or draught, are cut out, and
after the top and bottom are fitted in the whole is baked to solidify the same.
To enable this invention to be properly understood I will proceed to fully
describe the same with aid of the accompanying drawings.
Figure 1 is a partial perspective view of the usual form of apparatus for
expressing clay in drain-pipe manufacture; in this view the clay is shown by
the letter "A."
Figure 2 shows the upper and lower parts A, B, of a stove as first expressed.
Figure 3 sectional elevation of same, the parts A and B being taken on line x, x,
Figure 5.
Figure 4 a cross section of part A, on line, z, Figure 6.
Figure 5 outside elevation of parts A, B, with openings for fireplace door, and
ashpan.
Figures 6 and 9 sectional elevations of finished stove without ornamental top
and bottom; the latter figure being a view on line =**² Figure 8.
Figure 11 external elevation of finished stove.
Figure 12 external elevation of a modified form of construction of stove.
Figare 13 section of same on line y¹ y'.
Figures 7, 8, 10, and 14, are sectional views of parts.
The stove is preferred to be made in separate parts A, B, the former fitting into
the latter and may be left loose or be burnt together. In the shell is made the vertical
air passages b, and in the interior of A are the vertical passages a, a', a³, a³, a³, a³,
for the heat to pass up and down from the fire before passing out at ✓ (Figs. 8
and 9) to the chimney.
The passage of the heat from the fire being in the direction of the arrows
in Fig. 6.

passages a, a, a², a³, aª, a³, and forming top of fire-place n; m, projecting rim

top of A.
Figure 13, shows a form of stove intended to burn rubbish which is fed in at e,
passing down p into fireplace.
Figure 14, shows sectional view of a modification of the other views in which
the shell of the stove is solid and the interior fire passages instead of being formed
in one with the shell A, are made loose and arranged to be fitted in so that if
broken can be easily replaced.
Having now particularly described and ascertained the nature of this inven-
tion and in what manner the same is to be performed, 1 declare that what [
claim is :-
1-The improved construction and manufacture of pottery-ware stoves,
substantially as herein before described, and illustrated by the accompanying
drawings.
2-In the construction of pottery-ware stoves, expressing the same in one or two
parts and at same time forming fire passages in A, part, substantially as described
and illustrated by the accompanying drawings.
3-In the construction of pottery-ware stoves, the combination with the shell A,
of loose fitting draught passages for the heat from fire as illustrated at Figure 14,
in substitution for the fixed passages.
4-In the construction of pottery-ware stoves, forming air passages in the shell
part to enable air to pass through to carry additional heat into room.
