the Universal Inventors and Patentees Financial Company Limited 30 Finsbury
Pavement London E.C. in the County of Middlesex do hereby declare the nature
of said Invention for "IMPROVEMENTS IN JACKETTED HEATING STOVES a com-
munication to me from abroad by Max Schneider of Doos in the German Empire
to be as follows:-
"
According to these improvements the fireplace and the outer jacket are arranged
in the following manner:
A cast iron frame of round or rectangular shape is furnished at its under side
with teeth (zahnen) and above these teeth is connected with a fireclay ring.
Between this fireclay ring and the aforesaid cast iron ring is a hollow space which
is connected with the chimney by a pipe and the hollow base plate of the stove, so
that a continuous circulation of air takes place in this hollow fireclay space. The
air is drawn outside of the fire space through a pipe and serves to cool the frame to
increase ventilation and to burn the warmed air of the room.
The container for the frame is furnished with slits (schlitze) at three places by
which it is possible to apply frame supports outside the fire space
These supports
can be placed and fixed in any suitable way.
The frame may have three openings placed at equal distances like the supports
so that when the said frame is turned it can fall through or when the supports are
removed it can be taken out downwards through the fire door without the necessity
of taking the stove to pieces.
.
The container of the frame is furnished with small doors at both sides of the
upper part of the grate; these doors are closed with discs of mica and can be
connected with the outer jacket.
The object of this arrangement is to give access from two sides to the teeth
(zahnen) of the frame from the outside of a jacket stove for the purpose of
liberating the ashes.
The firereflector (Fuerspiegel) is above the fire clay frame connected with a belly
shaped frame and is closed by means of mica discs fixed in this frame On the

page_text: other hand this belly shaped frame communicates with the jacket of the stove at
the level of a register tile made of sheet metal, cast iron, clay or porcelain and
containing either inside or outside of the jacket of the oven an adjustable register
or damper. If the slide of this register is opened the stove fire protected by mica
discs is visible If the slide is closed the side radiating heat of the stove is arrested
and will take an upward direction in the jacket The opened register serves also for
increasing the circulation of air A series of rings are connected together over one
another by connecting screws Rosettes are fixed to the outside of these rings by
screws.
At the points where four stove tiles come together at their corners they are held
to the rings by the rosettes so that by removing the rosette each single tile can be
taken out or changed The whole jacket of the stove is made up in this way by
several rings The joints of two adjacent tiles can be covered with strips which
may be connected with the rosettes or be pressed thereby to the tiles.
The base plate may be of any suitable material and an insulating substance such
as clay cement or other bad conductor can be interposed as a protection for the floor
and as a substitute for a stone base.

I LORENTZ ALBERT GROTH K.G.V. Civil Engineer and Managing Director of
the Universal Inventors and Patentees Financial Company Limited 30 Finsbury,
Pavement London E.C. do hereby declare the nature of said invention for
"IMPROVEMENTS IN JACKETED HEATING STOVES a communication to me from
abroad by Max Schneider Gentleman of Doos, in the German Empire and in,
what manner the same is to be performed to be particularly described and
ascertained in and by the following statement:-
A cast iron frame A of round or rectangular shape is furnished at its under side
with teeth (zahnen) and is connected above these teeth with a fire clay ring b
Between this fire clay ring and the aforesaid cast iron ring A is a hollow space
connected with the chimney by a pipe C and the hollow base plate d of the stove
so that a continuous circulation of air takes place in this hollow fire-clay space
The air is drawn outside of the fire space through a pipes and serves to cool the
frame b to increase ventilation and to burn the warmed air of the room.
The container e for the frame is furnished with slits (schlitz) at three places by
which it is possible to apply frame supports fff outside the fire space These
supports can be placed and fixed in any suitable way.
The frame A may have three openings Fig 2 placed at equal distances like the
supports f so that when the said frame A is turned it can fall through or when the
supports are removed it can be taken out downwards through the bottom of the
stove without the necessity of taking the stove to pieces.
The container of the frame e is furnished with small doors i at both sides of the
upper part of the grate, these doors are closed with mica and can be connected with
the outer jacket Fig 1.
The object of this arrangement is to give free access from two sides to the teeth
(zahnen) of the frame from the outside of the jacket stove for the purpose of cleaning.
The fire domej (Feuerspiegel) is above the fire clay frame connected to a belly
shaped frame i and is closed by means of mica dises fixed in this frame. On the
other hand this belly shaped frame communicates with the jacket of the stove at
the level of a register tile made of sheet metal, cast iron, clay or porcelain while
outside the jacket an adjustable register or damper c k is fixed Figs 1 and 5.
If the slide of this register is opened the fire protected by mica discs is visible
If the slide is closed the side radiations of heat are arrested and will take an
upward direction in the jacket.
Fig 3 is a side view at right angles to Fig 1 of which Figs 2 and 4 are plans.
A series of rings m are connected together over one another by connecting
screws n. Rosettes o are fixed to the outside of these rings by screws At the
points where four stove tiles come together at their corners they are held to the
rings by rosettes so that by removing the rosette each single tile can be taken out
or changed.
The whole jacket of the stove is made up in this way by several rings The joints
of the tiles may be covered with strips which may be connected with the rosettes or
be pressed thereby to the tiles.
The base plate may be of any suitable perforated material and an insulating slab
of clay, cement, or other bad heat conductor can be interposed as a protection for
the floor and as a substitute for a stone base.

page_text: Having now particularly described and ascertained the nature of my said
invention and in what manner the same is to be performed I declare that what
I claim is
1 A round or rectangular heating stove provided at its lower end with a divided
cast iron frame a in connection with an inner fire clay ring b. A pipe s connecting
a and b with a hollow space for the purpose of establishing the continual ventilation
necessary for the burning and heating of the air and for cooling a. b. also the
combination of these parts with the pipe C through the hollow space for establishing
a regular circulation of air from the hollow base plate d to the chimney.
2. The fire clay frame e carrying a and b by means of the supports ƒfƒ ƒ at the
outside and the application of s passing through e.
3 The valve of the register c. k. to admit the hot air into the room.
4 The application of rosettes o in combination with rings m attached by means
of connecting screws n to each other in order to facilitate the work of taking the
stove to pieces.
5 The whole Jacketed heating stove combined and operating as before described
and illustrated in the drawings.
Dated this 22nd day of October 1884.
