IMPROVEMENTS IN COOKING RANGES
Year: 1884

page_text: I, JOHN MCINTYRE SHAW, of Nos 14 and 20 Union Street, 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 prevent the passage of cold air into the flues surrounding the ovens, and
when used as an open fire only, to arrest a portion of the flames and hot gases
which usually escape through the flue leading directly to the chimney, and direct
the said flames and gases so arrested beneath the hot plate and through the flucs
around the oven or ovens and in that manner to the chimney.
In carrying out these Improvements a plate or plates secured to the hot plate of
the cooking range is or are arranged at one or both sides of the fire space and
projecting downwards thereinto.-The distance between the side cheeks of the fire
space is greater than the distance between the two plates when two are used, or
when only one is used is greater than the space between such plate and the edge
of the hot plate on the opposite side of the fire space.-These plates being secured
at or near the edges of the hot plate, project over the fire space, so that such
projecting portions of the hot plate are subjected to a direct heat which is there-
after drawn across the top of and down around the oven or ovens, and so to the
chimney.

I, JOHN MCINTYRE SHAW of Nos. 14 and 20 Union Street, 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:-
My Invention, which relates to improvements in cooking ranges, has for its
object to prevent the passage of cold air into the flues surrounding the ovens, and
when used as an open fire only, to arrest a portion of the flames and hot gases
which, usually escape through the flue leading directly to the chimney and direct
the said flames and gases so arrested beneath the hot plate and through the flucs
around the oven or ovens and, in that manner to the chimney..
In carrying out the present improvements a plate or plates secured to or formed
in part with the hot plate of the cooking range is or are arranged at one or both
sides of the fire space and projecting downwards thereinto. The distance between
the side cheeks of the fire space is greater than the distance between the two
plates when two are used, or when only one is used is greater than the space
between such plate.and the edge of the hot plate on the opposite side of the fire
space. These plates being arranged at or near the edges of the hot plate, project
over the fire space, so that such projecting portions of the hot plate are subjected
to a direct heat which is thereafter drawn across the top of, and down around the
oven or ovens, and so to the chimney.

In order that my said Invention may be properly understood and readily carried
into effect,. I will now proceed to describe the drawings hereunto annexed.
Figure 1, is a front elevation of portion of a cooking range with the improve-
ments constituting my present Invention applied thereto.
Figure 2, is a vertical section of the same.
In carrying my present Invention into practice, a plate, or.(as represented upon
the annexed drawings) the plates a, secured to or formed in part with the hot
plate b, of the cooking range is or are arranged at one or both sides of the fire
space c, and projecting downwards thereinto. The distance between the side
cheeks d, of the fire space c, is greater than the distance between the two plates a,
when two are used, or when only one is used, is greater than the space between
such plate a, and the edge of the hot plate b, on the opposite side of the fire space c.
The plates a, being arranged at or near the edges of the hot plate b, project over
the fire space c, so that such projecting portions of the said hot plates b, are
subjected to a direct heat which, as indicated by the direction of the arrows at
Figure 2, is thereafter drawn across the top of, and down around the ovens e, and
so to the chimney. The front ends of the plates a, are or may be provided with
the transverse plates f, (Figure 1) or their equivalents so as to prevent any cold
air passing at this part into the Ques.
It is to be understood that to existing ranges my present improvements are
applied by securing to the hot plate b, the downwardly projecting plates a, which
with their continuous brackets are constructed somewhat in the form of pieces of

page_text: angle-iron, these, at their front ends being boxed or closed in, that is to say, the
vertical and horizontal members of the angle-iron united by a plate f, as herein-
before described with reference to Figure 1 of the annexed drawings.
Having now particularly described and ascertained the nature of my said
Invention and in what manner the same is to be performed; I declare that what
I claim is
.
The improvements in cooking ranges consisting of the plates a, projecting from
the hot plates b, over and downwardly into the fire space c, so that such projecting
portions are subjected to a direct heat which is thereafter drawn around the
ovens e, to the chimney, the cold air being prevented from passing into the flues
by the said plates and the end plates f, or their equivalents all substantially as
and operating in the manner hereinbefore set forth with reference to the annexed
drawings.
