North Britain for an Invention of "IMPROVEMENTS IN COOKING RANGES AND
PROVISIONAL SPECIFICATION left by the said James Carrick at the
Office of the Commissioners of Patents on the 30th June 1883.
JAMES CARRICK, of Glasgow, in the County of Lanark, North - Britain,
"IMPROVEMENTS IN COOKING RANGES AND OVENS,"
This Invention relates to improvements in the construction of cooking ranges
and of ovens forming part of such ranges, but adapted also for separate use.
The improved cooking range, which is by preference made to fit within the
usual chimney recess without building in, is constructed with the grate or basket
turned round at right angles to face sideways instead of to the front, and a space
is left or formed opposite the fire at the side of the range, wherein roasting or
similar cooking operations may be conducted. This cooking space is partly
enclosed by a hinged door or doors, and within this space is fitted a swinging plate
which is hinged to the outer shell of the range, and is made to fold down hori-
zontally on a level with the upper part of the fire grate to act as a hot plate on
which stew pans or hot dishes may be conveniently kept. An encased cooking
oven is fitted at one side of the range, but has no heating flue provided for it, tho
necessary heat being radiated through the shell of the oven at the side of the fire,
and by a metal plate forming the bottom of the oven, which extends outwards
from the side of the oven into the bottom of the fire grate, and which may form
the bottom fire bars. Below the fire-bars is by preference fitted a perforated plate
or a second series of bars which are made movable and which by means of a
handle outside may be made to cover partially or entirely the openings in the
fixed fire bars, to regulate the admission of air to the fire. A second oven or hot
chamber which is only heated at one side by the rising fire gases is fitted over the
main cooking oven, and a small closet or chamber may be fitted below the main
oven to serve as a plate rack. The side of the fire which faces the apartment in
which the range is fitted, is covered by a double cased hinged door or flap to

page_text: screen the cook or attendant, and an upper panel of glass or mica, or of perforated
sheet metal is formed or fitted in the front of the range over the hot plato to
admit of the condition of the firo being observed. The range is provided with a
boiler at the back, and is fitted with a smoke plate above, and a smoke canopy
through which the products of combustion pass into the chimney.
The oven which is by preference used is formed of sheet metal, or cast with a
double casing at top, bottom, and at three sides, the back or side of the oven
which faces the fire being alone made of a single thickness of metal, through
which the radiant hent of the fire is thrown. A strong plate of iron or other
conducting material forms the inner shell of the casing at the bottom, and this
plate is made to extend outwards to some distance at the side of the oven, and
into the bottom of the fire, the plate being there cut to form the bottom fire bars
as already described. The heat of the fire is conducted by the bottom plate to the
sole of the oven, and the radiant heat of the fire is readily conducted through the
thin metal side of the oven; and as the oven is double cased on every other side,
a bigh temperature may be got and be maintained within the oven. The front of
the oven is fitted with a hinged or other door, which also is double cased to
prevent conduction and radiation of heat. The double casing may be filled with
silicate cotton or other non-conducting material, or be simply a non-conducting
.air space surrounding the oven.
Cooking ranges of ordinary construction in other respects, may be fitted with
the improved double cased oven provided with a laterally projecting bottom plate
extending into the bottom of the fire, and conducting heat therefrom to the sole of
the oven.
The improved construction of oven described is also adapted for use with any
ordinary fire grate or fire-place. In this case, the encased oven is made portable
and is formed with a laterally projecting bottom plate extending outwards from
the back of the oven, the back being formed of a single thickness of metal.
In using the oven, it is placed with the back to the fire, and with the projecting
bottom plate fitted in the bottom of the fire over the usual grating.

JAMES CARRICK, of Glasgow, in the County of Lanark, North - Britain
"IMPROVEMENTS IN COOKING RANGES AND OVENS "
My said Invention relates to improvements in the construction of cooking
ranges and of ovens forming part of such ranges, but adapted also for separate use.
In the accompanying Drawings, which illustrate the Invention, Figure 1 is a
longitudinal vertical section; Figuro 2 a horizontal section; Figure 3 a front
elevation, and Figure 4 a transverse vertical section of a modification of my
improved cooking range. Figure 5 is a vertical section, and Figure 6 a sectional
plan of my improved portable oven as adapted for use with any ordinary
fire-place.
The improved cooking range, which is by preference made with a shell or
ensing A, adapted to fit in the usual chimney recess without building in, is
constructed with the grate or basket B turned round at right angles to face
sideways instead of to the front, and a space C is left or formed opposite the fire
at the side of the range, wherein roasting or similar cooking operations may bo
conducted. This cooking space C is partly enclosed by a hinged door or
doors D, D', and is provided with radiating plates c, so that it forms a species of
Dutch oven. Within this spaco C is fitted a swinging plate E which is hinged to
the outer shell A of the range, and is made to fold down horizontally on a lovel
with the upper part of the fire-grate B, as indicated in Figure 1, to act as a hot
plate on which stew pans or hot dishes may be conveniently kept. An encased!
cooking oven F is fitted at one side of the range, but has no heating flue provided
for it, the necessary heat being radiated through the thin single shell f of the oven
at the side of the fire, and by a metal plate F forming the bottom of the oven F,
which extends outwards from the side of the oven into the bottom of the fire
grate B, and which may form the bottom fire bara. Below the fire-bars may be
fitted a perforated plate or a second series of inovable bars, which by means of a
handle outside may be made to cover partially or entirely the openings in the
fixed fire-bars, to regulate the admission of air to the firo; otherwise, the admission
of air may be regulated by a valve or door g, fitted between the bottom of the
fire-place and the enclosed ash-pan G. A second encased oven or hot chamber H,
which is only heated at one side h by the rising fire gases, is fitted over the main
cooking oven F, and a small closet or chamber I is fitted below the inain oven F,
and is provided with shelves i to serve as a plate-rack. The side of the fire which
faces the apartment in which the range is fitted, is covered by a double cased
hinged door or flap B' to screen the cook or attendant, and an upper panel of
glass or mica, or of perforated sheet metal D¹ is formed or fitted in the front of
the range over the hot plate E to admit of the condition of the fire being observed.
The range is provided with a boiler J at the back, and is fitted with a smoke-plate
or damper K above, and a smoke canopy L through which the products of
combustion pass into the chimney.
The oven F, which is by preference used, is formed of sheet metal, or cast with
a double casing fat top, bottom, and at three sides, the back or side f of the
oven which faces the fire being alone made of a single thickness of metal, through
which the radiant heat of the fire is thrown. A strong plate F of iron or other
conducting material forms the inner shell of the casing at the bottom, and this.
plate is made to extend outwards to some distance at the side of the oven, and
.

page_text: into the bottom of the fire, the plate being thero cut or perforated to form the
bottom fire bars, as already described. The heat of the fire is conducted by the
bottom plate to the sole of the oven, and the radiant heat of the fire is also readily
conducted through the thin metal side fof the oven; and as the oven is double
cased on every other sido a high temperature may be got and be maintained
within the oven. The front of the oven is fitted with a hinged or other door F4,
which also is double cased to prevent conduction and radiation of heat. The
double casing of the oven and door may be filled with silicate cotton or other
non-conducting material, or be simply a non-conducting air space surrounding the
oven F.
Cooking ranges of ordinary construction in other respects, may be fitted with
the improved double cased oven F provided with a laterally projecting bottom
plate F extending into the bottom of the fire, and conducting heat therefrom to
the sole of the oven.
The improved construction of oven described is also adapted for use with any
ordinary fire grate or fire-place. In this case, the encased oven F is made portable
as is indicated in Figures 5 and 6 and is formed with a laterally projecting bottom
plate F extending outwards from the back of the oven, the back being formed of
a single thickness of metal.
In using the portable oven F, it is placed with the back to the fire, and with
the projecting bottom plate F¹ inserted between the horizontal or vertical bars of
the firo grate.
A sliding hook or catch f¹ is fitted on each side of the oven and carried so that
it may swivel on a guide rod f³. This catch may be hooked on to the front bars
of the fire grate when the oven is to be used, and then the oven may be placed
close to the fire or drawn out from the fire to a slight extent if the heat radiated
against the side and conducted by the plate or bars F¹ be too great.
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 ;-
First. The improved construction or arrangement of parts of a cooking range
herein described and illustrated in Figures 1, 2, 3, and 4.
Second. A cooking range in which the fire grate is fitted to face sideways and
the heat of the fire is directed into an enclosed space (C) wherein cooking
operations may be conducted, substantially as herein described and illustrated.
Third. As an integral part of a cooking range, the encased oven F, the sole of
which extends into or forms the bottom of the fire grate, substantially as herein
described and illustrated.
Fourth. A portable encased oven formed with a sole or plate extending out
beyond the bottom and adapted for insertion into an ordinary fire-grate,
substantially as described and illustrated in Figures 5 and 6.
In Witness whereof, I the said James Carrick, have hereunto set my hand and
seal this Twenty Seventh day of December, in the year of our Lord, One thousand
eight hundred and eighty three
