COMPLETE SPECIFICATION.
A New or Improved Gas Stove for Heating, Cooking, and Drying.
I HENRY HAMBIDGE, of 375, High Road, Chiswick, in the County of
Middlesex Confectioner, 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:-
My invention relates to a new or improved gas stove for heating, cooking, and
drying, whereby a great economy of gas is effected, the said gas being intimately
mixed with air before proceeding to the burners where it is ignited.
My improved stove which is preferably placed upon a suitable stand, comprises
two parts, the lower part, base, or stove proper consisting of a bed plate, furnished
with a curved groove of peculiar shape, a slot on one side for the admission of air
and a central burner having the shape of a ring forming part of the bed-plate and
within which is fixed another ring provided with three or more upright projections
arranged at equal intervals one from the other. The other part of the stove
consists of a cover perforated in the centre and furnished upon its underside with a
curved rib or strip of a shape corresponding to that of the curved groove aforesaid
so as to fit therein and form a channel open at one end wherein the gas mixes with
air on its way to the burners. The top of this cover is formed with a raised
pedestal preferably of square shape whereover can be fitted the lower end of an
oven when the latter is required for baking purposes. Upon this pedestal is formed
a ring which is open at one point of the periphery, surrounds the central perforation
of the cover and is used to place thereon when the oven is not in use, any cooking
utensil such as a kettle, saucepan, or the like. The central opening of the stove, is
closed by an iron disc furnished with perforations of suitable shape, this disc being
rendered incandescent by the gas flame.
One end of a suitable gas-jet is screwed in a tapped opening formed for this
purpose in the stove while its other end is connected by an india-rubber tube to any
handy gas supply pipe.
The stand is furnished inside with ledges or horizontal tabs fixed to the sides and
to the rear thereof and designed to receive a number of trays or slides on which is
placed any article of food requiring to be grilled or heated, a suitable door closing
the front part of this stand. In the accompanying drawings
Fig. 1 is a plan of my improved heating and cooking-stove
Fig. 2 is an underside view of the cover, and
Fig. 3 a plan of the stove proper, the cover being removed.
Fig. 4 is a central vertical section of the stove carrying the oven.
Fig. 5 is a front view of the stand.
Figs. 6 and 64, 7 and 7 and 8 and 84 are respectively a plan view and a central
section of three forms of perforated discs. My improved gas stove consists of three
parts, the standard s, the stove proper and the oven o. The stands is provided
with short legs or feet fand is furnished inside with ledges or horizontal tabs t
fixed to the side and at the rear of the same, upon which slide the metal trays m
designed to receive plates, dishes, or articles of food requiring to be grilled or
cooked, a door d provided with a knob or nandle ' closes the front of the same and
is retained in position by means of the projections 1. 1. The stove proper consists
of a bed-plate 6 provided with a curved groove c of peculiar shape and a slot e for
the admission of air as clearly shown in Fig. 3 of the drawings.
This bed-plate is further provided with a central ring burner 9 within which is
arranged another ring furnished with three or more tabs or uprights Z (Fig. 4)
serving as guides for the cover. The bed-plate is surmounted by a cover k open

page_text: centrally and furnished upon its underside with a rib c¹ (Fig. 2) of the shape
corresponding with that of the groove c (Fig. 3) wherein this rib fits when the
cover is put on and the stove proper is complete. This cover k has a tapped
perforation wherein is screwed the tapered end of the rectangular elbow or connec-
tion y (Fig. 4) the other end of which is rounded and connected by an india-rubber
tube, to any convenient gas supply pipe. Within the plate band the cover k is
thus formed inside the rib c¹ fitting in the groove c as above set forth, a circular
passage or channel partly obstructed by the deflecting strip h' (Fig. 3), wherein
the gas proceeding from the tapered end of the elbow or connection y and the air
proceeding through the slot e (Fig. 3) are intimately mixed and warmed before
gaining access to the perforations of the annular burner g, where the mixture is
ignited. This burner is a perforated ring which forms the inner wall of the
passage. In the central opening of the stove proper (Fig. 4) is formed
around the inner periphery of the same, a ledge n designed to receive one of
the discs shown in plan in Figs. 6, 7 and 8 and in central section in Figs. 6^,
7 and 8ª.
b
The oven o which is placed over the raised square part of the cover k, consists
of an outer casing and an inner casing closed in front by a door in the usual
manner, and around which play in the direction of the arrows, the heated air
and products of combustion proceeding from the burner, which escape through
the central opening o formed in the top of the said outer casing (Fig. 4).
H are handles for convenience of manipulation.
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 I
claim is :-
―:
1. The improved gas-stove for heating, cooking, or drying arranged, constructed,
and operating, substantially as herein described and shown.
2. In gas stoves for heating cooking or drying, forming the stove of two parts
containing a channel for the mixture of gas with air, substantially as herein
described and shown.
3. In combination with the gas stove above claimed, a removable oven, substan-
tially as herein described and shown.
