Improvements in Apparatus for the Cooking and Keeping Warm of
Food Stuffs for Poultry, Animals, and the like. :
I, JOHN HENRY DIXON JENKINSON, of Church Lane, Handsworth, near the City
of Birmingham, Chemist, do hereby declare the nature of this invention to be as
follows:-
This invention relates to an apparatus for cooking preparing or keeping warm
of food stuffs for poultry, game and other birds, dogs and other animals and the
like, and has for its object, to provide a simple and efficient apparatus by which
poultry and other foods may be expeditiously and economically cooked.
The invention consists primarily in employing in conjunction with natural or
ordinary conduction heat, an auxiliary heater in the form of a series of jets by
which steam is forced directly into and through the food being cooked.
One form of apparatus embodying my invention comprises a central vessel or
well, adapted to contain water to be boiled and surrounded by an ordinary casing
or shell containing a lagging of felt, asbestos or like material located "between
the walls of the casing and the well, so as to prevent the loss of heat by conduction
from the water well or boiler, which has situated underneath it, an oil or other
lamp or means for heating the water contained therein.
Depending into the water well or boiler is an open-topped cooking vessel,
covered by a suitable lid and supported, within the boiler by an annular flange
around its upper end resting upon like-shaped annular rests formed around the
top of the space between the outer jacket and boiler. The cooking vessel is of
smaller diameter than the boiler, so that there is an annular space between their
two walls, the upper part of which forms a steam chest, and the upper end of the
vessel is fitted with a series of steam pipes, curved or raking downwardly, with
their outer ends communicating with the aforesaid steam space and their lower
or depending ends coming near the bottom of the vessel, so that the live steam
generated from the water in the boiler is made to pass through the pipes into the
mass of the food, through which it has to insinuate before escaping so that the
food is not only cooked by the heat conducted to it from the water in the boiler
through the walls of the vessel, but is also subjected to a direct steaming process,
whereby the efficient cooking is economically and quickly performed.
To make a steam tight joint between the supporting flange of the cooking vessel
and the part upon which it rests, one or the other may be faced with felt or
other soft material, which when clamped down by screws, turns or other fasten-
ings, is compressed and prevents steam escaping, but I do not confine myself to
this particular joint, as the same result may be attained in various ways.
Instead of the cooking vessel being detachable, it may be fixed to or made up
with the boiler and in order to prevent the food from entering and clogging the
outlet ends of the steam pipes, they may be provided with nozzles or distributers.
Where the cooking vessel is fixed, the steam pipes may be detachably fitted, to
permit of the removal of the cooked food.

page_text: Instead of the steam being projected into the food through pipes or nozzles, it
may be made to pass through a perforated part of the walls of the cooking vessel,
and instead of the steam being generated in the surrounding boiler, it may be
generated in a separate vessel provided for the purpose.

Improvements in Apparatus for the Cooking and Keeping Warm of
Food Stuffs for Poultry, Animals, and the like.
I, JOHN HENRY DIXON JENKINSON, of Church Lane, Handsworth, near the City
of Birmingham, Chemist, 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 an apparatus for cooking, preparing or keeping warm
food or food stuffs for poultry game and other birds, dogs and other animals
and the like, and has for its principal object, to provide a simple and efficient
apparatus by which poultry and other foods may be expeditiously and economi-
cally cooked.
The invention primarily consists in employing in conjunction with natural
or ordinary heat transmitted by conduction an auxiliary heater in the form of a
series of jets by which steam is forced directly into and through the food being
cooked.
Figure 1 of the accompanying drawings represents a complete vertical section
of one form of food-cooking or warming apparatus constructed and arranged in
accordance with my invention. The cooker is shown in this view in operation.
Figure 2 is another sectional view of the said apparatus, but shows the several
parts dis-assembled from one another.
Figure 3 is a topside plan of Figure 1 but with the lid or cover removed.
Figure 4 represents a horizontal section of Figure 1 upon the dotted line .r.
The same letters of reference indicate corresponding parts in the several
figures of the drawings.
This form of apparatus embodying my invention comprises a vessel or well a,
adapted to contain water to be boiled and surrounded by an ordinary casing or
shell b, with a lagging c of felt, asbestos or like material located between the
walls of the casing b, and the well a, so as to prevent the loss of heat from the
water well or boiler, which has situated underneath it, an oil or other lamp or
means for heating the water contained therein.
Depending into the water well or boiler is an open-topped cooking vessel e
covered by a suitable lid e¹, and supported within the boiler by an annular
flange e, around its upper end resting upon like-shaped annular rest 2 formed
around the top. of the space between the outer jacket and boiler. The cooking
vessel is of smaller diameter than the boiler, so that there is an annular space f
left between their two walls, the upper part of which forms a steam space, and the
upper end of the cooking vessel is fitted with a series of steam pipes g, curved
or raking downwardly, with their outer end g' communicating with the aforesaid
steam space and their lower or depending ends 92 coming near the bottom of the
said cooking vessel, so that the live steam generated from the said water in the
boiler is made to pass through the pipes g, into the mass of the food contained

page_text: within the cooker and through which it has to pass before escaping, and thus
the said food is not only cooked by the heat conducted to it from the water in
the boiler through the walls of the vessel, but is also subjected to a direct
steaming process, whereby the efficient cooking is economically and quickly
performed.
To make a steam tight joint between the supporting flange of the cooking
vessel and the part upon which it rests a ring or washer h, made of felt or other
soft material may be interposed between them, and when this washer is clamped
down by turns such as h¹, or by screws or other fastenings, it is compressed and
prevents steam escaping, but I do not confine myself to this particular joint, as
the same result may be attained in various ways.
The steam pipes are preferably connected to the walls of the cooking vessel
by a screw union joint, such as i or in any other convenient manner.
Instead of the cooking vessel being detachable, it may be fixed to or made up.
with the boiler and in order to prevent the food from entering and clogging the
outlet ends of the steam pipes, they may be provided with nozzles or distributers.
Instead of the steam being generated in a surrounding boiler, it may be
generated in a separate vessel provided for the purpose.
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:-
First: In cookers or heaters for bird, animal and other foods, cooking or
heating the food stuffs by subjecting the same to the direct action of steam which
is forced into or through the mass of food contained within a cooking or heating
vessel, substantially as herein described, and also as set forth in the accompanying
drawings.
Secondly: In apparatus for cooking, heating or reheating of bird, animal and
ather foods, comprising a water well or boiler heated in any convenient way, and
a vessel adapted to contain the mass of food to be treated, and located or suspended
within the boiler, in conjunction with steam passages leading from the upper part
of the boiler into the interior of the cooking vessel for the purpose of directing
steam into the said food, which is cooked or heated partly by the direct action
of the live steam and partly by the heat conducted to it from the boiler, sub-
stantially as and for the purpose herein described, and also as set forth in the
accompanying drawings.
Thirdly: An apparatus for cooking, heating and reheating bird, animal and
other foods, consisting of a water well or boiler having located or suspended
within it, a detachable vessel adapted to contain the food, with a steami space
surrounding the cooking vessel, which is provided with fixed or detachable pipes
in communication with the steam space and depending into the mass of food,
which is cooked or heated partially by the direct action of the live steam, and
partly by heat conducted to it from the boiler, substantially as herein described
and also as set forth in the accompanying drawings.
Dated this 28th day of June 1900..
