I, EMA JÜRGENS, of No. 60, Friedenauer Strasse, Friedenau, near Berlin, in
the Empire of Germany, Teacher of Cooking, 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:-
The present invention relates to an improved cooking appliance, especially
adanted for baking cake or bread. the purpose of the invention being to so con-
struct this class of steam-heated devices that the chamber containing the food
to be cooked is kent perfectly dry, that it is uniformly heated from all sides,
that the steam produced by means of the device is confined and that the water-
receptacle can be refilled during cooking without disturbing the action of the
appliance.
With these ends in view the invention consists in certain novel features of
construction, combination and adaption of parts, all as more fully hereinafter
described, shown in the accompanying drawings, and the essential elements of
which are recited in the appended claims.
In the accompanying drawings, which form part of this specification, my
improved cooking appliance is shown in a vertical section.
The appliance essentially comprises the water receptacle a and the steam
chamber connected one with the other in any suitable and steam-tight manner.
The steam chamber is fitted with a double shell and suitably closed on top br
means of a lid & fitted with a safety valve c. The lid d which is likewise com-
posed of a double shell is suitably screwed or bolted on to the steam chamber b.
The space between the two shells of the steam chamber and of the lid d is
filled with hent non-conducting material of any suitable kind. The bottom e
of the steam chamber is fitted concentrically with an annular ridge ƒ externally
screw-threaded for the purpose of screwing thereto steam-tight a bell or dome g
of suitable material. Outside the annular ridge f the bottom e is perforated.
The water receptacle a is fitted with a water gunge and a suction-pump i,
the latter can be in connection with any suitable source of water supply.
The operation of my improved cooking appliance is as follows:--
After the water receptacle a has been filled to a suitable height with water the
food to be cooked is placed on the bottom e of the steam inside the annular
ridge and thereupon the bell or dome a is screwed lightly on to said ridge f.
The steam developed in the boiler 2 rises through the perforated bottom
the steam chamber enveloping the bell on all sides, so that the cake, bread
or other foodstuff contained in said bell is uniformly cooked. The condensed
steam is not lead off, but precipitates through the perforations in the bottom
hack into the water receptacle a. By means of the auction-nump the water
volume in the receptacle a can be kept constant during cooking, should it be
necessary, without disturbing the process of cooking.
of
It is obvious that I do not limit myself to any special dimensions of the annular
xide and of the holl

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 declaro that what
I claim is:-
1.) Cooking-appliance essentially composed of a water receptacle and a steam
chambed secured thereto, the bottom of the steam chamber fitted concentrically
with an annular externally screw-threaded ridge and perforated outside said
ridge, a bell adapted to be screwed on to the ridge, said bell adapted to cover the
foodstuff to be cooked, and a water guage and a suction-pump in connection with
the water receptacle, substantially as described and shown and for the purposes
specified.
2.) Cooking appliance comprising in combination a water receptacle fitted with
a water guage and a suction-pump for keeping the water volume constant, a
steam chamber covered by a lid fitted with a safety valve tightly secured to the
upper edge of the water receptacle, heat non-conducting material employed in
connection with the shell and lid of the steam chamber, an annular externally
screw-threaded ridge fitted concentrically to the bottom of the steam chamber,
said hottom perforated outside the annular ridge, and a bell adapted to be screwed
on to the annular ridge, said bell adapted to cover the footstuff to be cooked,
substantially as described and shown and for the purposes specified.
