Improvements in and relating to Stoves.

I, WILHELM WILMS of Hamm, Westphalia, in the 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 :-
This invention relates to stoves in which the fuel is fed from.the top and its chief
object is to obtain a more perfect combustion of the coal or other fuel and the
resulting gases or smoke.
A stove constructed according to this invention has its body divided into two parts
by a wall or partition through which are formed one or more openings provided
with doors. The front of the stove is furnished with an opening for the insertion of
fuel and with openings for the admission of air. The doors of these openings in
the front of the stove are connected by levers, links or the like to the doors of the
openings in the partition, so that when one of the latter is opened for the passage of
the products of combustion one of the former is also opened.
In order that my invention may be more readily understood I have hereto
appended a sheet of drawings to which I refer hereinafter.
Figure 1 illustrates one form of the improved stove in vertical section.
Figure 2 shews a vertical section of the stove taken at right angles to Figure 1.
Figure 3 represents a section taken along the line A-B, Figure 2.

Figure 4 is an illustration of a section taken along the line C-D, Figure 2.
The body of the stove is divided into two parts b and c by the partition a.
is introduced into the part e through the door d and this part is also provided
with external openings e¹, e, e, furnished with doors f. These openings are fitted
with grates or grids. At the bottom of the stove is a basket shaped grate o¹
underneath which are the bars o. A uniform current of air can thus be brought
against the contained fuel.
The partition a has three openings g¹, 92, 93, closable by sliding doors h¹, h³, h³,
operated from the outside of the stove. Each of these doors is so connected by
levers links or the like to one of the doors f in the front of the stove, that the two
connected doors must open and close simultaneously. The door is connected to
the door d the door to the door e, and the door h³ to the door .. A convenient
way of connecting two doors is by a lever one arm of which is provided with a
handle and is connected to the door in the partition and the other arm K of which
comes against the door f. The doors are weighted as at i so that they fall open
when the lever is moved away. When fresh fuel has to be fed through the door d
to a charge which is already ignited both doors and d are opened. Any gases or
smoke being emitted from the top of the fuel are thus drawn into the part c which is
in communication with the chimney or flue t; and cannot enter the compartment
in which the stove is placed.
The lighting of a fire within the stove is effected through the door e', the door n
being also opened. As soon as the fire is lighted further fuel is introduced through
the door d, the doors n and el continuing open for the supply of air to the grate o'.
When the bottom part of the fuel is ignited the sliding door h³ is opened and the
products of combustion pass through the opening 9³, air now entering at e². The
fire having increased, the doors of the openings and are opened. The fire is
thus always burning downwards and as fresh fuel is added the gases formed are
bound to pass through a layer of burning or incandescent fuel. With the progress
of the fire the openings 61, e, and are closed successively.

page_text: The products of combustion pass from the chamber c through the opening p and
after circulating around the heating chamber a through the passages r, are led
through the channels to the flue t.
When the fire is being first lighted the damper or plate u may be removed so as
to allow free and immediate access to the flue. The draught is thus considerably
increased.
If desired the top of the stove may be fitted with a tank or vessel of water so that
any necessary or desired degree of humidity may be imparted to the atmosphere.
The bottom part of the stove and the partition wall are preferably lined with a
suitable fire proof material.
Having now particularly described and ascertained the nature of my said inven-
tion and in what manner the same is to be performed, I declare that what I
claim is :-
1. A stove the body of which is divided into two parts by a partition furnished
with a series of openings, the doors of these openings being connected with the doors
of openings in the front of the stove, substantially as and for the purpose hereinbefore
described and as illustrated by the accompanying drawings.
2. A stove constructed and arranged substantially as hereinbefore described and
as illustrated by the accompanying drawings.
