Improvements in Apparatus for Heating and Cooking Purposes.
We, WALTER HERBERT HATCH, of 74 St. Peters Road, Great Yarmouth, in
the County of Norfolk, Tinsmith, and RICHARD FREDERICK ERNEST FERRIER
and JOHN ALBERT HENRY FERRIER, both of Hall Plain, Great Yarmouth,
aforesaid Gentlemen, do hereby declare the nature of this invention to be as
follows:-
This invention relates to improved apparatus for beating and cooking purposes.
Such an apparatus adapted for heating water and for cooking by baking, as well
as for frying and boiling purposes, comprises a casing having a couple of
longitudinal shelves or divisions so arranged as to form an open front lower
compartment for containing a lamp or lamps of any suitable construction for
heating by the combustion of suitable hydrocarbon, such as that popularly known
as paraffin, an upper compartment adapted to receive a boiler or water heating
vessel with flange at its front side to close the front opening in the said compartment,
and the bottom and four sides of an upper chamber to constitute a flue or flues
through which the hot gases resulting from the combustion of the hydrocarbon pass
by openings formed through the respective longitudinal shelves or divisions and
through the boiler. When the apparatus is to be used for frying, or cooking by
boiling, and so forth, a flanged piate or cover forming the top is placed on the top
of the casing so as to form a top to the upper chamber before referred to, this
plate or cover having a hole or holes therein over which a cooking utensil or
utensils can be placed and also perforation for escape of hot gases, but when baking
is to be done, there is substituted for this plate or cover, a jacketted oven
comprising an additional casing with a chamber within it so arranged as to leave a
space between the sides, top, bottom and back of said chamber and those of the
outer casing containing it, which is provided with a hollow door whose inner wall
is constructed with holes or perforations corresponding to similar holes or
perforations in the front of the jacket so that hot gases may enter the hollow door
in such wise that the entire oven or baking chamber may be surrounded by hot
gases which ultimately escape at the top. The hollow door is or may be provided
with a ventilator. Such a jacketted oven or baking chamber may in some cases
be used separately in conjunction with an appropriately formed bottom alapted to
be placed directly upon and supported by, the appropriate parts of a lamp the
flame and hot products from which will then pass through an opening or openings
in the said bottom and circulate through the space surrounding the oven and away
at the top. The boiler is or may be provided with a suitable projecting extension
open at top through which water may be supplied, this extension being furnished
with a lid below which there is an opening for escape of steam, and with a cross
bar or its equivalent to facilitate the boiler being charged to a suitable height with
water. Also a suitable cock or cocks for withdrawal of water is or may be
provided. When using liquid hydrocarbon lamps in connection with this apparatus,
we provide in front of the burner cones, perforated plates mounted to turn
downward on hinges and provided with mica so as to form small windows through
which the Hame can be seen, but which can be turned down to enable the flame to
be extinguished, or the wick to be ignited, without its being necessary for this

page_text: purpose to withdraw the lamp or its containing chamber from within the lower
chamber of the apparatus.

We, WALTER HERBERT HATCH, of 74 St. Peters Road, Great Yarmouth, in
the County of Norfolk, Tinsmith, and RICHARD FREDERICK ERNEST FERRIER
and JOHN ALBERT-HENRY FERRIER, both of Hall Plain, Great Yarmouth,
aforesaid, Gentlemen, 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 relates to improved apparatus for heating and cooking purposes
as we shall now describe with reference to the accompanying drawings, wherein
Fig. 1 is a front elevation, partly in section of the auparatus as arranged for
frying, or cooking by boiling,
Fig. 14 is a part transverse section on the line of Fig. 1.

Fig. 3 is a front elevation of the oven with its door wide open, the left hand
half of the oven being in longitudinal section.
Fig. 4 is a horizontal section of the oven with the door partly open.
Fig. 5 is a front elevation of an oven bottom secured on a lamp having two
burners, and Fig. 6 is a detail view thereof.
Fig. 7 is a front elevation of an oven-bottom, fitted on a single-burner lamp, and
Fig. 8 is an underside view of the last mentioned bottom.
Fig. 9 is a plan of the boiler with the lid of the water supply aperture open.
Fig. 10 is a perspective view of an oil lamp with hinged window.
The apparatus adapted for heating water and for cooking by baking, as well as
for frying and boiling purposes, comprises a casing 1 (Figs. 1 and 2) having a
couple of longitudinal shelves or divisions 2 and 3 so arranged as to form an open
front lower compartment 4 for containing a lamp 5 (or lamps) of any suitable
construction for heating by the combustion of suitable hydrocarbon such as that
popularly known as paraffin; an upper compartment 6 adapted to receive a boiler
or water heating vessel 7 (Fig. 9) with flange 8 at its front side to close the front
opening in the compartment 6; and the bottom and four sides of an upper
chamber 9 to constitute a flue, or it may be flues into which the single flue may
be divided, as shown, by a partition 10, and through which the hot gases resulting
from the combustion of the hydrocarbon pass by openings 11 formed through the
respective longitudinal shelves or divisions 2 and 3 and through the boiler 7.
When the apparatus is to be used for frying, or cooking by boiling, and so forth,
a detachable flanged plate or cover 12 (Figs. 1 and 24) is placed on the casing 1
so as to form a top to the upper chamber 9, this plate or cover having a hole or
holes at 13 therein (two holes are shown) over which a cooking utensil or utensils
can be placed, and also perforations formed between projections 13" extending
upwardly from the plate or cover 12 for escape of hot gases.
When baking is to be done, there is substituted for the plate or cover 12, a
jacketted oven (see Figs. 3 and 4) comprising an additional casing 15 with a
chamber 16 within it so arranged as to leave a space 17 between the sides, top,

page_text: bottom, and back of the chamber 16 and those of the outer casing 15 containing it,
which is provided with a hollow door 18 whose inner wall is constructed with holes
or perforations 20 corresponding to similar holes or perforations 21 in the front of
the jacket or casing 15 so that hot gases may enter the hollow door 18 in such wise
that the entire oven or baking-chamber 16 may be surrounded by hot gases which
ultimately escape at the top through holes 22 in the casing 15 of the oven. 16" is
a removable support formed of perforated sheet metal. The hollow door is or may
be provided with a ventilator 23 to allow of the escape through a tube or tubes 24,
of fumes, etc. from the baking chamber 16.
Such a jacketed oven or baking chamber may in some cases be used separately
in conjunction with an appropriately formed bottom adapted to be placed directly
upon and supported by, the appropriate parts of a lamp the flame and hot products
from which will then pass through an opening or openings in the said bottom and
circulate through the space 17 surrounding the oven and pass away at the top.
Fig. 5 shows such a bottom suitable for use with a two-burner lamp. It
comprises a plate 25 having inwardly bent flanges 26 at three sides so as to enable
the casing 15 of the oven, which is provided with a beaded or projecting lower
edge 27, (Fig. 3) to be readily slid into position on the plate and over the lamp.
The plate 25 is provided with depending chimneys 28, which are adapted to fit
around the cones 30 and above each of which the plate 25 is provided with an
opening to allow of the passage of the flames and hot products from the lamp 5
into the space 17 around the oven. The bottom plate 25 is fastened to the lamp 5
by two bent pins 31, one of which is shown separately in Fig. 6. The upper end
of each pin is permanently secured to an eye 32 on the bottom, in which it is.
capable of turning and sliding end ways, and the lower and shorter end of each
pin is adapted to engage, as shown, in an eye 33 on the lamp. Provision may
advantageously be made, as indicated in dotted lines in Fig. 5, for enabling the
chimneys 28 to be slid into and out of connection with the plate 25. Figs. 7 and 8
show an oven bottom likewise adapted to receive the oven-casing 15 and provided
on its underside with flanges 34 and 35 to fit the inside and the outside respectively
of the chimney-top of a single-burner lamp 5.
The boiler 7 (Figs. 1, 1 and 9) is or may be provided at its front side with a
suitable projecting extension 36 open at the top, through which water may be
supplied, this extensiou being furnished with a lid 37 below which there is an
opening 38 for escape of steam, and with a cross bar 39 or its equivalent to
facilitate the charging of the boiler with water to a suitable height, the top of the
bar being arranged at such a height that when the level of the water reaches it,
the boiler will be sufficiently charged. The boiler is or may be also provided with
a suitable cock 40 or there may be more than one, for withdrawal of water.
When using liquid hydrocarbon lamps in connection with this apparatus, we
provide in front of each burner-cone 30, a perforated plate 41 (see Figs. 1, 5
and 10) mounted to turn downward on hinges 42 and provided with a piece of
mica 43 so as to form small windows through which the flame can be seen, but
which can be turned outward and downward to enable the flame to be extinguished,
or the wick to be ignited, without its being necessary for this purpose to withdraw
the lamp or its containing chamber from within the lower chamber of the
apparatus, or to detach it from the oven when the latter is directly connected to
the lamp by a bottom plate 25.
Having now particularly described and ascertained the nature of the said inven-
tion and in what manner the same is to be performed we declare that what we
claim is :-
