Improvements in Stoves.
I ERNST FRIEDRICH EMIL GOLTERMANN, of 35 Schillerstrasse Hanover in
the Kingdom of Prussia and German Empire 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:-
1
This invention relates to stoves for heating rooms, and its object is to construct
them so that the fire may be quickly lighted and developed, and that they may be
charged according to the nature of the fuel and the desired temperature, either
with small quantities of fuel which are quickly consumed, or with a large quantity
of fuel which is consumed gradually and may be supplemented as required.
In order that my invention may be the better understood I now proceed to
describe the same with reference to the accompanying drawings and to the letters
and figures marked thereon. Like letters refer to like parts in the various figures.
Figure 1. is a vertical section of the stove.
Figure 2. is also a vertical section thereof, but at right angles to that shewn in
Figure 1.
Figure 3 is a horizontal section on the line I-I.
Figure 4. is a horizontal section on the line II-II.
Figure 5 is a horizontal section on the line III-III.
F is the shaft of the stove, R the fire grate, A the ash pit, T1 the door of the
fire chamber, T 2 the door to the fire grate, and T3 is the door of the ash pit.
A draft flue K is provided at the rear side of the stove and is divided by a
partition into two vertical flues V 1. and V 2. A valve is arranged at the top
of this partition and is adjustable from the outside by a handwheel and spindle.
This valve closes the vertical flue V 1, or the vertical flue V 2, according as to
whether, it is placed against a projection s' above the flue V 1, or a projection
above the flue V 2, while the flue which has not been closed remains in com-
munication with the chimney flue N situated in the middle plane of the stove above
the draft flue K.
The base Z of the stove is divided into two chambers by a partition w arranged
parallel to the front of the stove. One of the two chambers, viz. that which is
situated to the rear, is again divided by the partition of the flue K which reaches
into the base Z of the stove. In this way three chambers 01 02 03 are formed,
of which O1 communicates with the vertical flue V1 and O2 with the vertical
Blue V 2, while the chamber 03 communicates with the two chambers O1 and O2
by openings in the partition wo which divides the base of the stove.
The rear wall of the stove has three openings a. b. c. within reach of the vertical
Alue V 1. The upper opening a connects the vertical flue with the shaft of the
stove, and the two lower openings connect the flue with the fire chamber T₁ and
the ash pit A respectively. The openings b and c can be closed by slides b₁ and c₁
respectively.
When the stove is to be used with small quantities of fuel, the valve is placed
into the position shown in the drawings, in which it rests against the projection s 2,
and the slide b₁ is drawn. The flame of the fire which has been started on the
grate with easily combustible material (in order to light the charge of fuel to
be placed on it afterwards) passes then, partially through the opening b and
partially through the opening a₁ into the flue V and thence into the chimney.
The shortness and width of the passage through which the gases of combustion
pass favours the developement of a large flame which heats the stove quickly.

page_text: The
When the easily combustible material is burning sufficiently, the 'fluel which is
really intended for beating is placed on it. When this charge is burning
sufficiently, the valve is turned so as to rest against the projection .
gases of combustion pass now also through the openings a and b into the flue V',
but they pass therefrom downwards into the base chamber O₁ and from there
through the chamber 03 into the chamber 02, from which they rise in the
fluc V2 and escape into the chimney. A passage is thus provided for the
gases which is of great length which favours their complete combustion and
causes them to yield their heat to the stove. In order to cause the gases to
heat also the outer walls of the chamber 03, a projection or partial partition 14
is provided in the chamber 03 on the partition w.
If the stove is to be used with a large charge of fuel, filling the shaft F, the
opening is closed by the slide 61. The flame of the material used for lighting
the fire passes then only through the shaft F and gives its heat only to the
Bаme. If the stove is then filled with fuel intended for heating, and when the
same is sufficiently alight, the valve is turned so that the gases of combustion
pass only through the charge of fuel in the shaft F into the flue V 1, because
the opening remains closed. The gases then pass, as in the previous case,
through the chambers O₁ 0 3 0 2 and the flues V 2, N into the chimney.
The opening c mentioned herein before serves to admit cold air from the ash
pit into the flue V 1 in order to lessen the draft, when desired.
Having now particularly described and ascertained the nature of my inven-
tion and in what manner the same is to be performed, I declare that what I
claim is;
1st. A stove having two vertical flues V 1 and V 2 at its rear, a partition
dividing such flues, provided with an adjustable valve at its top which interrupts
direct communication between the flue V 1, or the flue V 2 with the chimney,
according as to whether it is turned to. one side, s1, or to the other side & 2 in
order to lead away the gases of combustion into the chimney, either through the
two vertical flues V 1 and V 2 and the base Z, connecting the latter, during
the firing of the stove, or through the vertical flue V 1 only at the lighting of
the fire.
2nd. In such a stove an adjustable opening between the vertical flue V₁ and
the space over the grate R, which when open allows the gases of combustion to
pass direct into the flue V, and which, when closed by the slide 61, causes the
gases to rise in the shaft F from which they pass into the flue V 1.
