Improvements in or relating to Utensils or Vessels for Cooking
by Steam.
I, EDWARD WILLIAM PARISH, of No. 1, Elm Street, Belgrave, in the County
of Leicester, Traveller, do hereby declare the nature of this invention to be as
follows:-
This invention consists of improvements in or relating to utensils or vessels for
cooking by steam, applicable to ordinary cooking pots or vessels for cooking fool or
fodder by super heated steam in the manner and by the means hereinafter described.
In appliances or vessels now in use for cooking by steam, the super heated
steam by its own force escapes direct through the lifting of the lid of a sauce-
pan or steamer or other such domestic appliance used in cooking thus admitting
particles of cold air in to the pot or cooking chamber and reducing the temperature
by variation to such a degree that the cooking is not satisfactorily accomplished.
The object of this my invention is to obviate this and provide a cover of a
cylindrical form the bottom of which will be upon the bottom of the saucepan,
cooking pot, or base of the outer chamber except upon the over pressure and
ultimate discharge of the super heated steam which causes the cover or cylinder to
rise and discharges itself into the boiling water in the pot or outer chamber which
comes only up to the bottom of the inner cage or cooking cylinder, and rises up the
sides of the cover or outer cylinder thus keeping it at a uniform heat, the said
outer cylinder is provided with a handle, or other lifting device and fits over an
inner wire cage, corresponding in shape or may be a perforated metal case or wire
gauze cage, or perforated inner cylinder in which is fitted a tray or dish with
suitable lifting devices attached thereto for the purpose of putting in or taking out
of the tray or dish carrying the articles to be cooked, more than one of these trays
or dishes may be used if desirable, both the outer and inner cylinders, and dish, or
dishes to fit may be of any shape circumferently, or of any length to fit any shaped
pot or cooking utensil.
When the water boils the outer cylinder or cover will rise and fall with the
pressure of steam concentrated therein, and will discharge the super heated steam
and it will rise up the outer sides of the cover or cylinder and keep the whole at a
uniform heat during the steaming or cooking operation, no lid being required to be
used, and doing away with ordinary steamers in saucepans, cooking pots, or culinary
vessels now in common use.
This invention will be found especially applicable in constructing a cooker for
forage or provender for cattle on the lines as herein described by the concentration
of super heated steam.
By the aforesaid means puddings can be placed in the tray or dish and lowered
into the cage or inner cylinder without cloths or without being tied up, and meat,
such as chops, steaks, kidneys, or fish and poultry which now by steaming lose their
flavour retain by the use of my appliance the whole of the juices and vegetables
keep their natural flavour by the action of the super heated steam becoming
concentrated in the cover or cylinder.
It will be noticed by the up and down motion of the cover if the water is boiling
away, or requires replenishing.
may make the inner cage or cylinder with the outer one to any length in order
to admit of a series of trays to be held therein for different dishes to be steamed at
one time but allow of no escape of the super heated steam except through the
bottom of the cover as before described.

Improvements in or relating to Utensils or Vessels for Cooking
by Steam.
I, EDWARD WILLIAM PARISH, of No. 1, Elm Street, Belgrave, in the County
of Leicester, Traveller, 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 consists of improvements in or relating to utensils or vessels for
cooking by steam, applicable to ordinary cooking pots or vessels for cooking food
or fodder by super heated steam in the manner and by the means herein
illustrated and described reference being had to the several figures in the drawings
annexed, in which,
Figure 1, is a sectional view of the appliance showing the outer cylinder A, over
the inner perforated one B, which is lifted out of the ordinary belly shaped
cooking pot C, by the handle &², the pot can be placed over a gas cooking stove D,
or its equivalent. the jets d', being carried in the arm, of the supply pipe or
fittings E. Potatoes are shown in the cooking chamber B, on the perforated base b'.
Figure 2, is another sectional view of the cooker, showing a corrugated or fluted inner
cooking cylinder B, the outer cover A, fitting in the conical shaped pot C, provided
with handles c', which for general farm uses for cooking fodder may be substituted
by trunnions which would fit into any ordinary carriage to be wheeled about, in
this case it would be necessary to construct the apparatus of stout iron or the like
and provide a heating chamber or fire box at bottom.
Figure 2, is a top view of the corrugated inner cylinder B, showing the
perforated bottom &', fitting in the cover or outer cylinder A.
Figure 3, is a modification of the previous figures in which it will be seen the
trays F, having the lifting devices, placed in the inner cylinder B, and have
therein the vegetables such as green peas and the like fa, and fowl and the like f³,
the outer cylinder being provided with handles a', at the sides. The cooking
pot C, fitting in a recess in the heater G, which holds the oil or spirit lamp H, or
may be gas jets to heat the small supply of water required to cook with.
Figure 4, shows an arrangement for cooking food or fodder for cattle, poultry
and the like, the cooking pot C, being placed over the fire in a brick built furnace G,
ordinarily constructed with flue for the smoke from the grate H, to go through
the chimney 1, the inner cylinder B, holding the fodder, fits in the outer cover
or cylinder A, by flutings, or raised bars J, made in the side thereof.
Figure 5, shows another modification of the cooker suitable for steaming or
poaching eggs, kidneys, fish, or the like, the inner tray F, having the handle f',
over which is fitted the outer cover A, by a vertical slot a², in the side thereof, the.
inner tray may rest on a rim, or both may rest on the bottom of the fry pan C.
In appliances or vessels now in use for cooking by steam, the super heated
steam is by its own force allowed to escape direct through the lifting of the lid of
a saucepan or steamer or other such domestic appliances used in cooking, thus
admitting particles of cold air into the pot or cooking chamber and reducing the
temperature by variation to such a degree that the cooking is not satisfactorily
accomplished.

The object of this my invention is to obviate this and provide a cover A of a
cylindrical form the bottom of which will be upon the bottom of the "saucepan,"
cooking pot," or base of the outer chamber C, except on the over pressure and
ultimate discharge of the super heated steam which causes the cover or cylinder A,
to rise and the steam to discharge itself into the boiling water in the cooking
pot or outer chamber which comes only up to the bottom b', of the inner cage or
cooking cylinder B, or by having a hole as at a² and a³, in the cover or cylinder A,
the steam rises up the sides of the cover or outer cylinder and escapes into the
cooking pot C, the said outer cylinder being provided with a lifting handle a', or

page_text: handles; or other lifting device and fits over the inner cage or cylinder B, corre-
sponding in shape and made of wire, or a wire gauze cage, or perforated "as seen
in Figure 1, corrugated, or fluted and in which may, or may not be fitted a tray
or trays F, to hold the articles, and fitted with suitable lifting devices such as "f³,
Figure 3" attached thereto, the rim, forming a chamber in which the super
heated steam is generated, and fitting the bottom of the pot, both are made of any
shape circumferently or of any length to fit any shaped pot or cooking utensil.
And will do away with ordinary steamers fitted to saucepans, cooking pots, or
culinary vessels now in common use.
This invention will be found especially applicable and useful in steaming or
cooking forage or provender for cattle upon the lines herein described, for field
purposes as shown in Figure 4, or domestic or agricultural uses as shown in any of
the others made to the size required. I can supply the outer and inner cylinders
made of tin, or any suitable metal or material to fit into ordinary coppers or the
like which have fire grates under them for the purpose herein referred to. And
the pot, copper, or chamber C, may be made portable and carried on wheels, all
the outer cylinders will be provided with a flange a³, to come about level with the
top edge of the saucepan or outer chamber.
In the small sizes of cookers for domestic use such as shown in Figure 3,
puddings can be laid in the tray or dish F, and lowered into the inner cage or
cooking cylinder B, without cloths or being tied up, and small chops, steaks,
kidneys, fish, poultry which now by steaming lose their flavour, retain it by the use
of my appliance, and the whole of the juices are kept in, and vegetables keep their
natural flavour, and corn or maize for poultry which if steamed in the ordinary
way does not expand or soften to form a nourishing food, but if maize is steamed
by my cooker it will not only soften but will swell out to a state resembling green
corn, and the poultry will cat it eagerly consequent upon it assisting digestion and
assimilation, for steaming liquids a plain inner cylinder B, fluted in
desired way
any
may be used without perforations in the base thereof.
For cooking kidneys and the like fat may be employed instead of water.
It will be well understood that my principle of cooking by steam with two
cylinders comprising an inner cage and cover is applicable to any bowed or
conical shaped culinary vessel, pot, pan, copper or the like for domestic or other
steam cooking purpose.
Having now particularly described and ascertained the nature of this my inven-
tion, and in what manner the same is to be performed, I declare that what I
claim is :-
1. In combination with ordinary culinary vessels or receptacles, for domestic
cooking, the employment of an inner cooking chamber or cylinder, and cylindrical
cover for steaming food or provender.
2. In culinary vessels of the character described the arrangement of a plain,
perforated, corrugated or fluted inner cage or cylinder B, with tray or trays F,
therein, and covered by an outer cylinder, A with outlet hole a, and flange a³...
3. Improvements in or relating to utensils for cooking food or fodder by steam
consisting of an outer pot or chamber, in which is fitted a cylindrical cover A,
an inner cage or cooking cylinder B, having a plain or perforated bottom above
the rim, all arranged substantially in the manner set forth.
Dated this 10th day of January 1891.
