AN IMPROVED COOKING APPARATUS
Year: 1856

page_text: LETTERS PATENT to John Green, of No. 37, Charlotte Street, Portland
Place, Marylebone, in the County of Middlesex, for the Invention of
"AN IMPROVED COOKING APPARATUS."
Sealed the 27th February 1857, and dated the 17th October 1856.
PROVISIONAL SPECIFICATION left by the said John Green at the Office"
of the Commissioners of Patents, with his Petition, on the 17th October
1856.
I, JOHN GREEN, of No. 27, Charlotte Street, Portland Place, Marylebone,
in the County of Middlesex, do hereby declare the nature of the said Invention.
for "AN IMPROVED COOKING APPARATUS," to be as follows:-
My improvements consist in making a light and yet strong semicircular
screen of tin or other suitable material with continued flat sides, which
produce great advantage when placed before the fire, the bottom of which
screen has an opening covered by a lid perforated with holes. Underneath
the screen is a small closet, for the convenience of placing a can or vessel to
receive the gravy from the opening at the bottom of the screen during the
process of roasting, the can or vessel being so conveniently placed that the
cook can take it at pleasure for charging and recharging (when necessary)
the self-acting gravy pan that is placed on the top of the screen, which has a'

page_text: regulating screw or slides for controlling the gravy or fat, as may be required.
Undeneath this self-acting grayy pan it is so arranged as to cause the gravy
or fat, or both, to flow on different parts of the meat while roasting.
The top of the screen is fix'd, and made on a bevel or incline, and con-
sequently it causes a powerful reflection of heat to the meat during roasting.
There is also a gibbet or gallows, made of iron or other metal, which is
attached to the screen at the back, and rises therefrom and extends in a curve
over the top of the screen, supporting the bottle jack and a chain; this chain
passes through a hole at the top of the screen from the bottle jack for
suspending the meat thereto. At the back or side of the screen.is placed a
door, affording the cook every accommodation that may be required. There
are also two or more shelves, which may be placed inside the screen on rests,
placed therein for that purpose, and taken out at pleasure; these shelves can
be used for baking and other purposes during the process of roasting.
The other part of my. Invention is a square tin or iron oven, which can be
used separately or in conjunction with the screen, one end being open for the
purpose of placing in front of the fire; the other end has a door or lid, and
when open is so arranged as to fit close to the screen, and thereby conducting
the whole of the heat from the front of the fire to the meat; there are also
shelves, which may be used at pleasure for baking pastry and other things;
there is also a door or opening at the side for regulating the fire.
My Invention also combines a new construction of power in the bottle jack,
which power is worked by a spiral or flat spring made of steel or other metal,
or a spring composed of india-rubber placed within a tube or otherwise, for
the purpose of giving motion to the movements of the jack.
Having now described the nature of my Invention, and the manner in which'
the same is to be performed, what I claim is, the reduction of cost, and
simplifying the construction of the screen, as follows:-
Firstly, the present apparatus is much lighter and stronger, and at the same
'time more convenient.
Secondly, the arrangement of a fixed bevel or angle top to the screen with
gravy pan thereon, with one screw or slide, for the purpose of diffusing the fat
or gravy over various parts of the meat while roasting.
•
Thirdly, the door or opening at the back or sides, for the greater accom-
modation of observing the progress of roasting.
Fourthly, the improvement of shelves that can be placed or removed at
pleasure, and which shelves can be so placed as to concentrate the heat for the
more speedy roasting of a small joint, and can be removed for the roasting of
à large joint.

page_text: Fifthly, the arrangement of the shelves for the baking of pastry and other
things at the same time as when roasting.
SPECIFICATION in pursuance of the conditions of the Letters Patent, filed
by the said John Green in the Great Seal Patent Office on the
2nd March 1857.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, JOHN

NOW KNOW YE, that I, the said John Green, do hereby declare the
nature of my said Invention, and in what manner the same is to be per-
formed, to be particularly described and ascertained in and by the following
statement, that is to say:-
My improvements consist in making a light and yet strong semicircular
screen of tin or other suitable material with continued flat sides, which pro-
duce great advantage when placed before the fire, the bottom of which screen
has an opening covered by a lid perforated with holes. Underneath the screen
is a small closet, for the convenience of placing a can or vessel to receive the
gravy from the opening at the bottom of the screen during the process of roasting,

page_text: the can or vessel being so conveniently placed that the cook can take it at
pleasure for charging and recharging (when necessary) the self-acting gravy pan
that is placed on the top; or under the top of the screen, which has a regulating
screw or slides for controlling the gravy or fat, as may be required. Underneath
this self-acting gravy pan it is so arranged as to cause the gravy or fat, or
both; to flow on different parts of the meat while roasting.
The top of the screen is fixed, and inade on a bevel or incline, and con
sequently it causes a powerful reflection of heat to the meat during roasting.
There is also a jibbet or gallows, made of iron or other metal, which is attached

baking and other purposes during the process of roasting.
The other part of. my Invention is a square tin or iron oven, which can be
used separately or in conjunction with the screen, one end being open for the
purpose of placing in front of the fire; the other end has a door or lid, and
when open is so arranged as to fit close to the screen, and thereby conducting
the whole of the heat from the front of the fire to the meat; there are also

modation of observing the progress of roasting.
Fourthly, the improvement of shelves that can be placed or removed at

page_text: pleasure, and which shelves can be so placed as to concentrate the heat for
the more speedy roasting of a small joint, one shelf having a hole for the chain
of the jack, and also an arrangement for the basting pan, which can be removed
for the roasting of a large joint.
Fifthly, the arrangement of the shelves for the baking of pastry and other
things at the same time as when roasting.
Sixthly, the improvement in the bottle jack, as herein-before described.
In witness whereof, I, the said John Green, have hereunto set my hand
