IMPROVEMENTS IN COOKING RANGES
Year: 1884

page_text: I JOHN MCINTYRE SHAW of Glasgow in the County of Lanark, North Britain
Ironmonger do hereby declare the nature of the said invention for "IMPROVEMENTS
IN COOKING RANGES" to be as follows:-
This Invention, which relates to Improvements in Cooking Ranges has for its
object to economize the fuel burnt therein, and to prevent the escape of smoke by
consuming the same.
The Invention consists in constructing Grates of the Cooking Ranges in two or
more portions, such portions being situated at a different level, that is to say, some
portions of the Grate of the Cooking Ranges are at a higher level than other
portions. By means of this arrangement of the Grates or bars, the red hot or
ignited fuel is raked to one or more portions of the Fire place, and the green or
unburnt portion of the fuel is charged to another part, their relative positions being
such that the gases and smoke issuing from the green fuel cannot escape without
either passing partly or wholly through the red hot fuel or the flames thereof, or
the flames produced by the ignition of a portion of the gases or smoke in proximity
to the red hot fuel passing wholly or partly through the unburnt or green fuel, or,
without passing through the green fuel, these flames may ignite the smoke or
gases escaping from the green fuel.

page_text: I, JOHN MCINTYRE SHAW, of Glasgow, in the County of Lanark, North Britain,
Ironmonger, do hereby declare the nature of my said invention for IMPROVEMENTS
IN COOKING RANGES and in what manner the same is to be performed, to be
particularly described and ascertained in and by the following statement:-
This Invention, which relates to improvements in Cooking Ranges, has for its
object to economise the fuel burnt therein, and to prevent the escape of smoke by
consuming the same.
The Invention consists in constructing grates of the Cooking Ranges in two or
more portions, such portions being situated at a different level, that is to say, some
portions of the grate of the Cooking Ranges are at a higher level than other
portions. By means of this arrangement of the grates or bars, the red hot or
ignited fuel is raked to one or more portions of the Fire place, and the green or
unburnt portion of the fuel is charged to another part, their relative positions being
such that the gases and smoke issuing from the green fuel cannot escape without
either passing partly, or wholly, through the red hot fuel or the flames thereof, or
the flames produced by the ignition of a portion of the gases or smoke in proximity
to the red hot fuel passing wholly or partly through the unburnt or green fuel, or,
without passing through the green fuel, these flames may ignite the smoke or gases
escaping from the green fuel.,
In order that my Invention may be properly understood and readily carried.into
effect, I will proceed to describe the drawing hereunto annexed..
T
This figure of Drawing is a transverse section through the fire, place, of a Cooking
Range constructed according to and constituting my, present Invention,
"
2
In carrying ou tmy present Improvements, I construct the grate of such Cooking
Ranges of one or more portions at different levels, that is to say, the portion a, being
on a lower level than that of the portion b.-This grate may be formed at its
bent or rising portion c, of one continuous or, solid plate, or, as shewn, upon the
annexed drawing, it may constitute, simply a set" or bend in all the ribs of the
said grate. By means of this arrangement of the fire grate, the red hot or ignited
fuel d, is or may be raked up on to the portion b, of the said grate, while the green
or unburnt portion of the fuel e, is charged on to the, lower, portion a, of. the said
grate. The relative positions of the red hot or burnt, and the green or unburnt
fuel, is such that the gas and smoke, issuing from the said green fuel e, cannot
escape through the flue f, without passing either partly or wholly through 'the red
hot fuel d, or the flames arising, therefrom; or the flames produced by the ignition
of a portion of the gases, or smoke in proximity to the red hot fuel d, passing
wholly or partly through the unburnt or green fuel e, in the event of side flues
being used; or, without passing through the green fuel e, these flames may ignite
the smoke or gases escaping from the said green fuel.

It is to be understood, although I have hereinbefore described and shewn upon
the annexed drawing a construction of fire grate wherein the bent or rising
portion c, is at a distance from the front of the range, that I may construct a grate
whose said bent or rising portion c, is closer to the front, by which means a large
and economical, roasting fire may be produced.-It is further to be understood, in
place of forming the grate in one piece as represented on the annexed drawing,
that I may construct a grate of analogous properties with a series of "set
or bent
fire bars supported at their front and rear ends upon bearing bars or their
☐ equivalent.

page_text: Having now described and particularly ascertained the nature of my Invention
and in what manner the same is to be performed, I declare that what I claim is :-
In Cooking Ranges, a grate whose front or forward portion is lower than its
back or rearward portion substantially as and for the purposes bereinbefore set forth
with reference to the annexed sheet of drawing.
