Fig. 1 shews a vertical section of the stover
Fig. 1 a separate view of the central passage & taken in section at right angles to
Fig. 1.
Fig. 3 is a section taken at right angles to Fig. 1.
Fig. 5 is an external front view.
Figs. 2, 4, 6, 7, 8 and 9 are various cross sections of the apparatus designed to shew
the arrangement, form and construction of the parts.
Concentrically to the exterior casing, in the shape of a cylinder C, is affixed the
chimney K and baking place A and heating chambers F and F are applied. The
baking place or cooking chamber A is formed by a fixed top, a moveable bottom and
fixed sides which have an opening Z (Figures 1, V and VII) through which the
baking room can be accessible in operation. The rotating bottom is in the shape of a
star or radiating framing, the separate segments being covered with fire clay, tiles
glazed or other suitable covering adapted to evenly diffuse the heat (see Figures 1
and 7) and the outer circular frame of the same is provided on its lower part with a
circle or series of cog teeth into which the teeth of the wheel or rotating part 2¹

page_text: The bottom of the baking chamber d externally is supported in its rotation upon
several rolls or wheels supported from the casing C, while internally and around the
centre flue it is easily movable on antifriction balls or rollers p suitably held in
grooves (Fig. 1) in such manner that the baking surface can be rotated with great
facility by means of the handle w. The top of the baking chamber is also formed of a
star or radiating series of frames F (Fig. 6) covered with fire tiles or like suitable
material in order to permit of the hent being evenly diffused throughout the baking
chamber A. To heat the oven a fire place is arranged at a and the fuel employed
may be coal or wood or other suitable fuel and from a the heating gases mount over
the bridge a' rearward of the fire (Fig. 3) into the flue passage or chamber F under
the baking chamber A. In the chamber F there are a number of metal deflecting
plates applied bent in the form of tangential curves which serve to distribute the gases
evenly under the baking chamber surface. Finally the heating gases pass over to the
chimney K through an opening after having passed through the whole lower
chamber F. The space between the top metal sheet a² and the lower part a³ is filled
in with sand or ash and thereby the heat is maintained evenly and the heat prevented
from passing into the lower parts of the baking oven.
The baking chambor A is constructed with fire proof tiles or like material in the
interior part, in the shape of a ring in order that the heat therein may be retained
therein and may not be transmitted to the outer construction of the baking oven.
Between the fire clay or tile surface d of the baking chamber and the bottom metal
sheets thereto (Fig. 3) may further be applied a layer of sand in order to facilitate
a perfectly even distribution of heat from the fire draught to the baking surface.
C
The heating gases which arise through the chimney are forced by the cover to
enter through the opening g' (Fig. 3) and pass over the surface gg of the baking
chamber in order thereby to still further heat the surface of the latter. The roof of
the baking chamber is also formed star shaped or a radial framing of wrought iron set
with tiles and the heating gases are also made to pass between metal plates bent into
the curves shewn so as to be deflected to pass over and heat the roof of the baking
chamber A evenly. The fire draught or flue chamber F is formed (Figs. 1, 3
and 8) over the baking chamber A in such manner that when as described the heating
gases have passed through the flue chamber F¹ and have parted with their whole hont
which can be utilized they enter through an opening which which is made in the
metal plate into the upper space or chamber F of the oven and from thence after
having passed through the valve o they pass out through the pipe into the air or
into a chimney or fluc. In order to facilitato the cleansing of the central chimney, it
is made open at the top and is closed whilst in use by a hand cover m so that after
taking off the latter, the other cover is readily accessible and the chimney throughout
can be easily cleaned. The fire draught chambers or flues, in order to facilitate
eleansing of same are provided with cloaring holes m¹ (Figs. 2, 3, 5, 8) which are
closed by means of tight fitting covers and means of securing them. In order to
regulate the draught into the oven flues as it may be required the chimney can be
closed more or less by means of the valvor which can be worked from the outside and
the chimney draught thereby regulated and the air entering through the ash pit
opening augmented or diminished as required.
The ashes and cinders which fall out of the fire draught or flues F, F, F into the
chimney when the same is being cleaned can be taken into the ash pit and at s can be
removed therefrom.
y is a diagonal rib or tie connecting the exterior shell of the oven with the central
chimney shaft and in this simple way they support each other.
In order to make the baking oven reliable in every possible respect it is preferably
provided with a clock the 3rd movable hand of which is set when the matters to be
baked are put in so as to shew the minute when the matters were placed in
chamber A.
A thermometer is affixed from outside by which roadily to read the temperature
-within and accordingly to regulate it.
The oven can also be supplied in a suitable manner with a steam vapour or moisture

page_text: producing vessel out of which the steam, vapour or moisture can be led through a pipe
into the baking chamber and such may be applied in a suitable manner in one of the
fire draughts or flues, in the baking chamber or on the oven.
By means of the arrangement or construction of rotatory baking surface or floor,
the baking or cooking stove described is readily workable and can be emptied and
filled with facility; the construction of fire draughts or flue chambers F, F1, F' in
combination with the bent guiding plates and i and the chimney k ensures the
utmost possible economical utilization of the fuel. The general arrangement of the
oven admits of its utilization as a baking oven and as a roasting oven for use of
Bakers, Confectioners, Hotels and other users as well as for large and small private
houses or other establishments. The apparatus may be made in various sizes and the
fire place may be single or duplicated or otherwise increased.
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 Baking Stove, oven or cooking apparatus of annular form having a rotatable
hearth, floor or sole plate d, guiding plates and i arranged to direct the heating
under and above the baking or cooking chamber, central pipe or shaft K. and
having openings ¹ and g¹ for even distribution of the heating gas.
gases
2. A Cooking Stove or Baking apparatus of annular form provided with a
rotatable floor to its baking chamber and means for distributing, regulating and
applying heat therein, all substantially as and for the purposes set forth.
