PROVISIONAL SPECIFICATION.
Improvements in Cooking Apparatus.
I JANE TROTTER SHAW residing at The Empress Hotel, Union Street
Sunderland, in the County of Durham Hotel Manageress do hereby declare the
nature of this invention to be as follows:-
My invention has reference to cookers and hot plates heated by coal gas, oil
lamps or other suitable fuel, wherein any kind of vegetables, fish or other food
requiring moist heat may be cooked or kept hot.
The object of my invention is to so construct a boiler that any variety of
vegetables, fish or other food may be cooked or kept hot with one boiler without
the aroma or flavour of any one of them impregnating that of the other, this I
attain in the following manner.
I construct a boiler which may be of any shape, and made of any suitable
material, and I divide the said boiler into two or more watertight compartments
each compartment being provided with a hole in the top, wherein I place ordinary
steam pans with perforated bottoms and loose lids, such as are used for cooking,
potatoes etc., and in these said steam pans is placed the articles to be cooked or
kept hot.
The heat required to boil or keep hot the water in the boiler may be obtained by
burning coal gas, oil lamps or other suitable fuel.
By concentrating the heat at any one place underneath the boiler I am enabled
to vary the temperature of the water in the various compartments, thus the
water may be kept boiling in one or more compartments, and in the others
moderately hot.

COMPLETE SPECIFICATION.
Improvements in Cooking Apparatus.
I JANE TROTTER SHAW residing at The Empress Hotel, Sunderland, Hotel
Manageress 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 :-
My invention has reference to cookers and hot plates heated by coal gas or oil
lamps or other suitable fuel, wherein any kind of vegetables, fish or other food
requiring moist heat may be cooked or kept hot.
The object of my invention is to so construct a boiler that any variety of
vegetables, fish or other food may be cooked or kept hot with one boiler without
the aroma or flavour of any one of them impregnating that of the other, this I
attain in the following manner, 1 construct a boiler which may be of any convenient
shape, and made of any suitable material, and I divide the said boiler into two or
more watertight compartments, each compartment being provided with a hole in
the top wherein I place ordinary steam pans with perforated bottoms and loose
lids, such as are used for cooking potatoes and the like, and in these said steam
pans is placed the articles to be cooked or kept hot, and where it is necessary to
have the article to be cooked immersed in the water I construct a steam pan

page_text: having a long end so as to reach to the bottom of the boiler, this long end, around
its circumference, being perforated, and also the bottom, for the admission of water.
The heat required to boil or keep hot the water in the boiler may be obtained by
burning coal gas, or by means of oil lamps or other suitable fuel.
By concentrating the heat at any one place underneath the boiler I am enabled
to vary the temperature of the water in the various compartments, thus the
water may be kept boiling in one or more compartments, and in the others
moderately hot.
One or more of the said compartments may be kept without water, and heat will
he generated therein from the heat of the surrounding compartments containing
water, these said compartments without water can be used for keeping articles hot
after being cooked, or for re-heating anything required, and constitutes what is
termed hot plates.
For supplying the boiler with water, each compartment may be fitted with a
turn cock, connected to one common main pipe, which may be connected to the
town's supply or other available source. Each compartment may also be fitted
with a drain cock for running the water off.
In order that my invention may be more fully understood and carried into
practice I will now proceed to describe the same with reference to the accom-
panying drawings in which similar letters are used to indicate corresponding parts
throughout.
The accompanying drawing represents a cooker and hot plate having eight
compartments.
Fig. 1 is a plan view shewing four steam pans in position and four removed.
Fig. 2 is a side elevation shewing steam pans in position.
Fig. 3 is an end elevation shewing steam pans in position.
Fig. 4 is a side elevation of a long steam pan so as to reach to the bottom of
boiler and Fig. 5 is a plan on the bottom of same.
In Figs. 1, 2 & 3, a is the boiler as a whole, bare the watertight compartments, care
the steam pans, d are the holes in the top of compartments for the reception of the
steam pans, e are gratings for the admission of air to underside of boiler, f is the
main supply pipe and 9 are the turn cocks for same, h are the drain cocks for
emptying the compartments.
Fig. 4 is a side elevation of a long steam pan and Fig. 5 is a plan on the bottom
of same, are the holes for the admission of water.
Having now particularly described and ascertained the nature of my inven-
tion and in what manner the same is to be performed, I declare that what I
-claim is,
A combined cooker and hot plate as and for the purpose herein described and
illustrated.
