This Invention relates to the manufacture of a stove having gas as a fuel, and
which can be used either as a cooking or heating stove; and also to appliances
which can be used either with gas or other stoves for cooking and heating purposes.
A casing is made, preferably of cast iron, larger at the bottom than at the top,
and from one to two feet in height as may seem best. A rim may be placed and
fastened to the bottom part of the said casing to diminish the danger of its being
upset. An ordinary gas supply pipe is inserted through the side of the casing, and
at the centre of the inside of the casing another pipe is joined to the one mentioned
above, and which passes upward to near the top of the casing and is there fastened.
A perforated plate is placed across the inside of the casing near the top, which is
covered with a radially corrugated concave cap, which forms a mixing chamber
and air inlet that does not interfere with the regular flow of the gas, the corrugated
plate containing channels to conduct the gas to the burning point. A rim is placed
and fastened to the top of the stove for the purpose of supporting a heating drum
or cooking utensils; a metal plate is also placed centrally within the casing and
immediately below the orifice of the supply pipe.

page_text: Also a heating drum, being a metal cylinder of any convenient height, but pre-
ferably of about two feet, and of a diameter of any convenient size, closed only at
the top, and surmounted by a perforated ornamental rim extending upwards.
Inside this cylinder is another cylinder of less diameter than the outer one and
open at the top (preferably of sheet iron), and extending to within two or three
inches of the top of the inside of the said outer cylinder, permitting the heat to
pass downwards to the space between the inner and outer cylinders, thereby heating
the two drums and materially increasing the heating surface. The space between
the inner and outer cylinders is closed at the bottom part by being there joined to
the outer cylinder, and thus a circular orifice is left for the admission of heat (to be
supplied from a stove below), equal to about one half of the diameter of the outer
cylinder, but affording means for resting it on a flange or stove to which it can be
further secured by another perforated rim affixed to the bottom of the outer cylinder,
which rim extends downwards to the extent of about two inches, and is made to
fit over the top of a gas or oil stove so as to securely hold it in its position, and
when fitted on becoming part of the stove itself and thereby greatly extending its
heating surface. By using the two (or double) cylinders in this way a gas or oil
stove can be changed at pleasure from a cooking to a heating stove.
Also an article to be fixed to a gas or other stove designed for boiling and
steaming a variety of different kinds of food with the same vessel 'simultaneously,
it being a metal boiler divided into several compartments by vertical partitions pro-
vided with a depression in the bottom of each compartment.
Also a water heater contained within a casing, which casing is open at its upper
and lower sides and which may be placed over the boiler hole of a gas or other
stove at its upper side is adapted to receive and contain a cooking utensil.
Also a triangular cone shape, preferably of sheet iron, to be fixed to a gas or
other stove and fitted with recesses for the purpose of holding and heating flat irons
and keeping them ready for use, and also a metal cover for the same.
Also another apparatus for cooking by steam whereby the food to be cooked is
placed in a vessel or steamer enclosed in an outer casing in which the water is
placed. The steam entering the top of said vessel or steamer is then conducted
by a compartment or compartments again through the boiling water before entering
the chamber containing the food to be cooked, thus drying the steam and com-
pleting the operation.
SPECIFICATION in pursuance of the conditions of the Letters Patent filed by
the said Charles Henry Green in the Great Seal Patent Office on the 17th
August 1877.
CHARLES HENRY GREEN, of Number 211, Gresham House, Old Broad Street, in
the City of London. "IMPROVEMENTS IN THE ARRANGEMENT AND CONSTRUCTION
OF GAS STOVES AND UTENSILS TO BE USED THEREWITH, AND FOR OTHER PURPOSES."
(A communication from abroad by Edward Benson Cox, of the City of Brooklyn,
State of New York, in the United States of America.)
Figure 1 in the accompanying Drawings represents the stove with the heating
drum placed in position.
Figure 2 shews merely the stove itself, on which may be placed the heating
cylinder or cooking utensils, as may be required.
Figure 3 is a cross section of the stove and heating drum, shewing the con-
struction of each.
Figure 4 is a section of the stove, shewing its interior construction.
Figures 5 and 6 represent how the same principles as utilised in the stove may
be applied to an ordinary gas burner for heating small quantities of liquids.
The casing A is made preferably of sheet metal rivetted or fastened at the bottom
to a stand made of cast or sheet metal, and at the top to a cylinder h³, h¹, to which

page_text: is fastened the ring H which acts as a support for heating cylinder or cooking
utensils. The gas supply pipe E passes through the casing, joined in the centre:
by another short pipe, through which the gas is forced upward to the burning
point, first passing through an air mixing chamber; c, c, is a perforated diaphragm ;>
and D, a radially concave corrugated cap which is firmly secured by the bolt F,
passing lengthwise through the casing hooked on to the supply pipe E, and secured
at the top by screw nut f. The space between the cap D and diaphragm c, c, forms
a mixing chamber for the air and gas, and the concave cap contains channels for
conducting the gas to the burning point, giving a large surface of flame; G is a.
metal plate placed below the orifice e of the supply pipe, and forms within the case
an annular air inlet which does not interfere with the regular flow of gas.
The whole combined forming a gas stove with improved combustion, and which can
be used either for cooking or heating purposes, or both, at pleasure.
When it is desired to construct a stove for heating purposes solely the ring H is
then dispensed with and an ornamental outer casing and heating drum is con-
structed of any form that may be desired. M is a heating cylinder or drum
constructed of sheet metal with an inner cylinder N, N, which extends upwards to.
within a few inches of the top and through which the heat passes in the direction
of the arrows, escaping through the apertures R, R, R. The drum is entirely closed
at the top and partially at the bottom P, P. This drum is adapted both for gas
and oil stoves; and can be placed on the stove or removed at pleasure.
Figures 5 and 6 shew the same principle adapted to ordinary gas burners for-
heating small quantities of fluids in a short space of time; B is the ordinary gas
burner passing through the bottom of the casing, which is also perforated for the
adinission of air; D is the corrugated concave cap which is the burning point of
the gas.
Figure 7 represents a vessel made of metal, preferably of tin, of any dimensions,
from one foot in height and six inches in diameter. It consists of a metal boiler
(marked in the accompanying Drawing), the which is placed over the stove,
Fig. 4. It is divided into compartments by means of three vertical partitions, and
over a metal covering are placed three vessels, preferably made of tin, and
marked 8, 8, 8, each of which is a steamer provided with a depression in the bottom.
By the simultaneous use of all the parts of this apparatus three or more different
kinds of food can be prepared for consumption at one and the same time.
Figure 8 represents a water heater in four or more compartments, marked
T, T, T, T, contained within a casing marked P, both made of metal, preferably of
tin; said casing is open at its upper and lower ends, and may be placed over a gas
or other stove so as to admit the heat in and around said compartments which are
all connected and filled with water. At its upper end V it is adapted to receive a
cooking utensil. At the side are two pipes, marked W, made of metal, which are
adapted to convey steam or water laterally into a cistern, marked X, intended to
contain soiled linen or other similar material, and by means of the steam generated
and hot water to boil the linen as in the ordinary course of washing by boiling.
Figure 9 represents a triangular cone shape iron heater, made preferably of sheet
iron, with a flange of same material. It is intended to be placed on a gas or other
stove, and is fitted with three recesses for holding and heating flat irons.
Figure 10 shews the same cone with a cover of tin made to fit and to retain the
heat generated by the stove, and to assist in the more perfect heating of the irons
by preventing the escape of heat.
Figure 11 shews the section of the apparatus complete.
