Complete Specification Left, 18th Mar., 1896-Accepted, 9th May, 1896
I, ERNEST EDWIN HOFFMANN of No. 128 Ohornerstrasse Pulsnitz, Germany,
Coppersmith do hereby declare the nature of this invention to be as follows :-
This steam-cooking pot admits of uniformly exposing the liquid in the pot, on all
sides, to the heat of the steam, the pot, at the same time being easily removed or
changed.
The cooking pot consists of a boiler-like formed receptacle, in which a second
semi-globular receptacle is fixed. This serves for the reception of the liquid.
Between the two receptacles are two or more pipes, which are bent sidewards at the
upper end. Both pipes meet in a channel which is connected to a steam pipe. The
channel runs through the center of two parts. One of these parts, which is fastened
to the receptacle, has near to the channel two other borings, which discharge into a
circularly formed groove arranged in one of the parts referred to, this groove being
connected to a vertical channel.
The respective part is connected with the plate of a cooking hearth or such like,
and hollowed out in semi-globular form. In this cavity is the correspondingly
shaped upper part. Both parts are bound together by a bayonet-socket fastening,
the hooks of which afford a tight connection of the two parts.
The cooking-pot is provided with a circular foot, whilst the plate has a circular
projection by which the cooking pot receives its proper position on being placed
upon the plate.
If the cooking pot is to be used, the pot is fixed to the part below by means of
the bayonet-socket fastening; then the shut-off valve, of a steam pipe which is
connected with it, is opened, so that the steam passes into the channel, and from
there into two pipes. At the outlet openings of the same, the steam is diverted
laterally by the bent ends of the pipes, so that it can circulate around the sides of
the receptacle, in order to uniformly heat its contents. The condensed water
collected at the bottom of the receptacle flows through borings into a groove and
from there through the vertical channel into a collecting box below.

I, ERNEST EDWIN HOFFMANN of 128, Ohornerstrasse, Pulsnitz, Germany,
Coppersmith, 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 steam-cooking pot admits of uniformly exposing the liquid in the pot, on
all sides, to the heat of the steam, the pot, at the same time being easily removed
or changed.
The drawing shows in Fig 1 the cooking pot in longitudinal section, and in
Figs. 2-5 single parts.

page_text: The cooking pot consists, as Fig. 1 shows, of a boiler-like formed receptacle a, in
which a second semi-globular receptacle b is fixed. This serves for the reception of
the liquid. Between the two receptacles a and b are two or more pipes c, c, which
are bent sidewards at the upper end. Both pipes c meet in a channel d which is
connected to a steam pipe. The channel d runs through the center of the parts ef.
The part e, which is fastened to the receptacle a, has near to the channel d two
borings g g', which discharge into a circularly formed groove arranged in the
part f, this groove being connected to a vertical channel i.
The part is connected with the plate k of a cooking hearth or such like, and
hollowed out in semi-globular form. In this cavity is the correspondingly shaped
upper part e. Both parts are bound together by a bayonet-socket fastening, the
hooks n of which, by the motion of the bevels m, m afford a tight connection of the
two parts.
The cooking-pot is provided with a circular foot o, whilst the plate k has a
circular projection p by which the cooking pot receives its proper position on being
placed upon the plate k.
If the cooking pot is to be used, the pot is fixed to the part below by means of
the bayonet-socket fastening; then the shut-off valve, of a steam pipe which is
connected with it, is opened, so that the steam passes through the short part q
into the channel d, and from there into the two pipes c c. At the outlet openings
of the same, the steam is diverted laterally by the bent ends of the pipes cc,
so that it can circulate around the sides of the receptacle, in order to uniformly
heat its contents.
The condensed water collected at the bottom of the receptacle a flows through
the borings g and g' into the groove h, and from there through the vertical
channel into a collecting box below.
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 :
Cooking pot, to be fixed by means of a bayonet-socket fastening and having
between the double bottom, two or more steam pipes c c laterally bent at the upper
end; by which the liquid receptacle is uniformly enveloped in steam, the condensed
water being conducted through two vertical channels g and g' into a horizontal
groove h, out of which it flows through the vertical channel i into a collecting box,
as set forth.
Dated this 14th day of March 1896.
