PROVISIONAL SPECIFICATION.
Improved Construction or Arrangement of Steam Cooker or Heater.
I CHARLES LAMB HANCOCK of 29 Oxford Street, Dudley, Worcestershire, Domestic
Appliances Manufacturer do hereby declare the nature of my said invention to be as
follows:-
The object of this invention is to cook food by steam heat, said steam having a free
circulation within the vessel or cooker, for an equal action upon all parts of the casing
and upon the substances within it. The water may be boiled by gas jet, lamp, fire
or otherwise.
This invention relates to the construction of a square or rectangular shaped casing
having side ledges on the interior for supporting removable trays. The casing is
provided with a series of plates or screens set at an angle above each of the tray
supports.
These supports have holes in them forming a communication between each tier of
supports and the bottom which serves as a receptacle for water.
For cooking or heating purposes the food or other substance or material is placed
upon the trays, and these when slid into position on the supports can be shut in
by a door.
Instead of the bottom forming a water vessél a pipe or pipes may be fitted to supply
steam or boiling water thereto, or the bottom may be so shaped that it may be placed
in a shallow vessel containing water.

COMPLETE SPECIFICATION.
Improved Construction or Arrangement of Steam Cooker or Heater. *
I CHARLES LAMB HANCOCK of 29 Oxford Street, Dudley, Worcestershire, Domestic
Appliances Manufacturer do hereby declare the nature of my said invention and in what
manner the same is to be performed, to be particularly described and ascertained in
and by the following statement:—
The object of this invention is to cook food by steam heat, said steam having a
free circulation within the vessel or cooker for an equal action upon all parts of the
casing and upon the substance within it. The water may be boiled by gas jets,
lamp, fire, or otherwise.
My invention will be understood by the annexed drawings.
Figure 1 is a part sectional elevation.
Figure 2 an end elevation showing the interior.
Figure 3 shews one of the trays removed.
The apparatus consists of a square or rectangular shaped casing A having side
ledges B, B, on the interior for supporting removable trays C, C. The casing A is
provided with a series of plates or screens D, D, set at an angle above each of the
tray supports B.
These plates or screens D have holes E in them forming a communication between
each tier of supports and the bottom F which serves as a receptacle for water.
For cooking or heating purposes the food or other substance or material is placed
within or upon the trays which are perforated and these when slid into position
on the supports B can be shut in by à door G, said door fitting close to prevent
escape of steam.

page_text: Instead of the bottom F forming a water vessel, a pipe or pipes may be fitted to
supply steam or boiling water thereto, or the bottom may be so shaped that it may
be placed upon a shallow vessel containing water which can be heated.
Very little water is required for the apparatus, there being no waste by evaporation
or escape, but I prefer to make the water reservoir of sufficient depth to hold a
quantity, part of which may be drawn off by the tap H for ordinary washing up
purposes; or meat or other food can be boiled in said water.
The apparatus shewn on the annexed drawings is specially adapted for cooking
meat puddings, potatoes and other edibles capable of being cooked by steam heat and
as each tray has a perforated bottom and is placed over the sloping partition D all
condensed moisture falling from the trays passes down the partitions D and then
flows through the openings E down the walls of the casing into the lower water
vessel each tray by this means being separated from the next above it.
There being no escape of steam from this apparatus the water reservoir does not
require recharging during the cooking operation.
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 1
claim is :-
The construction of a square or rectangular shaped casing provided in the interior
with sloping partitions. D, as covers to trays when slid therein and as means for
catching the drips of condensed steam and directing them back to the lower trough,
as set forth.
The 15th day of March 1890.
