PROVISIONAL SPECIFICATION.
Improvements in and Applicable to Open Ranges and Stoves used
for Cooking.
I, CHARLES THOMERSON of 263 Hackney Road in the county of Middlesex,
Plumber, do hereby declare the nature of this invention to be as follows:-
This invention relates to improvements in and applicable to open ranges, and
stoves used for cooking, and has for object to render them more efficient.
Open ranges and stoves as constituted at present for cooking are defective in so
far, that when a pot, kettle or other cooking utensil of a size slightly less than the
opening at the top of the fire, is put thereon, the smoke and other products of
combustion are in many cases caused to pass into the room in which the range or
stove is fixed. The cooking capacity of the range or stove is also limited to the area
of the fire opening.
To obviate these inconveniences I provide a grating or its equivalent which
extends over the fire opening & hob or hobs of the range or stove, and is so con-
structed that a sufficient space is left between it and the hob or hobs to enable the
flame & products of combustion to pass freely beneath the said grating to heat
several cooking utensils, the said products then passing between the said utensils and
up the chimney flue.
The grating may be formed integral with the range or stove or made separate
therefrom.
COMPLETE SPECIFICATION.
Improvements in and Applicable to Open Ranges and Stoves used
for Cooking.
1, CHARLES THOMERSON of 263 Hackney Road in the county of Middlesex,
Plumber 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 improvements in and applicable to open ranges and stoves
used for cooking, and has for object to render them more efficient.
Open ranges and stoves as constituted at present for cooking are defective in so
far that when a pot, kettle or other cooking utensil is placed on the top of the fire,
the smoke and other products of combustion are in many cases caused to pass into
the room in which the range or stove is fixed. The cooking capacity of the range or
stove is also limited to the area of the fire opening.
To obviate these inconveniences I provide a grating or its equivalent, which
extends over the fire opening and hob or hobs of the range or stove, and is so con-
structed that a sufficient space is left between it and the hob or hobs, to enable the
flame and products of combustion to pass freely beneath the said grating so as to
heat several cooking utensils, the said products then passing between the said utensils
and up the chimney flue.
In order that my invention may be fully understood, reference is had to the
accompanying drawing, in which,
Figure 1 is a plan and Figure 2 an elevation of a grating constructed according
to my invention.
Figure 3 is a front elevation of an open cooking range having one of my gratings
applied thereto, and
Figure 4 is a section on the line ≈ ≈ of figure 3.

page_text: Figures 5 and 6 are plans of modifications of my grating.
Like reference letters indicate like parts throughout the drawing.
a, figures 1 to 4, is the grating which is composed of a series of bars bb con-
nected at their ends to bars c c, the spaces d à between them forming openings
through which the flame and products of combustion can freely pass.
The bars c c which rest upon the top or bobs of the range are of sufficient depth
to allow of a space being formed between the bars bb and the said top or hobs of the
range, so that the flame and products of combustion can pass between the said top
and any cooking utensil which may be supported on the said bars b b.
I sometimes hinge the grating a to the top of the range so that it can be turned
up out of the way if required as shewn by the dotted lines in figure 4. For this
purpose, I provide the top of the range with slotted lugs ee with which engage the
ends of one of the bars b b which are made to project beyond the bars cc as
shewn. When the grating is not hinged it rests upon the top of the range. Or
instead of forming the grating separate as shewn in the drawings it may be formed
integral with the range.
Figure 5 represents a plan of a grating formed with a plate f having openings 999
for receiving the cooking utensils, the openings d d for the flame and products of
combustion being at the ends of the grating.
Figure 6 represents a plan of another form of grating in which a bar ½ of the
shape shewn and of the same depth as the bars c c is arranged at the back of the
grating and serves to prevent the flame & products of combustion passing away at
the back of the grating.
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) A grating or its equivalent for use in combination with open cooking ranges
or stoves, constructed substantially as and for the purposes described.
(2) An open cooking range or stove having a grating or its equivalent applied
thereto or formed integral therewith substantially as and for the purposes described.
(3) The various forms of gratings substantially as described and represented in the
accompanying drawing.
(4) The improved open cooking range or stove substantially as described and
represented in figures 3 and 4 of the accompanying drawing.
Dated this 9th day of April 1890.
