Improvements in Cooking Ranges.
We, GEORGE GORDON BRODIE and JAMES DAMREL PRIOR, of the Eagle Range
and Foundry Company, Limited, Catherine Street, Aston, near Birmingham, in
the County of Warwick, Iron Founders, do hereby declare the nature of this
invention to be as follows: -
Our invention consists of the improvements hereinafter described in cooking
ranges.
One part of our invention consists of the construction and arrangement of the
parts hereinafter described for ventilating the kitchen in which the range is
situated by carrying off the smell arising from the cooking. Another part of our
invention consists in forming, in the manner hereinafter described a hot closet in
connection with the range in which hot closet, plates, joints of meat and other
articles of food may be kept hot. Another part of our invention consists in the
arrangement hereinafter described for regulating the draught of the range.
For ventilating the kitchen or for carrying away the smell of the cooking, we
use in front of the plate rack of the range a hood or canopy, which is also used in
connection with the hot closet. This hood or canopy is hinged by its top horizontal
edge to the extreme top of the front of the range, and the said hood or canopy
is capable of a rising and falling motion on its hinge. The front of the hood or
canopy consists of a flat metal plate, made in one, two or more pieces, and the ends
of the said plate are provided with sector shaped wings at right angles thereto,
the said front plate and its ends or wing pieces constituting a hood or canopy,
which can either be raised on its hinge into a horizontal position or depressed into
a vertical position, or adjusted in an inclined or intermediate position. In the
highest or first position described, the hood is situated about level with the cover-
ing in plate and the front of the hood being entirely removed from the front of
the plate rack or hot closet, does not interfere with the putting of the plates and
articles of food into and their removal from the hot closet. When the hinged plate
is raised into its inclined or intermediate position it constitutes a hood or canopy
in front of the plate rack or hot closet and assists in ventilating the kitchen by
collecting, and carrying away the smells from the cooking range to the main
chimney at the back of the range.
When the front plate of the hinged hood or canopy is depressed into its vertical
position it closes the front of the plate rack and converts the plate rack into
a hot closet for the purposes hereinbefore pointed out.
The hinged hood or canopy may be supported in one of the positions described
by weighted levers, or by weighted chains and rollers; or the hood or canopy
may be locked in its adjusted position by ratchets on the wings of the hood with
which ratchets a self acting or hand worked pawl, fastened to the front bar of the
plate rack, engages. These ratchets may be made of any desired length so that
the hood may be adjusted at any at any desired height.

page_text: To regulate the combustion of the range we make an opening at the back of the
hot closet herein before referred to. This opening is either connected with the
boiler flue or with the oven flue above the damper. In the said opening we fit
a plate or valve which may be opened or closed either automatically by the draught
of the chimney, or mechanically by a hand worked rod and knob. When the
plate or valve is arranged to be worked automatically it may be hinged either at
top, bottom or side; and when it is to be worked mechanically, the rod and knob
in connection with the door or valve, may be brought to the front of the range
between the front plates of the canopy.
Our improvements may be applied to cooking ranges burning solid or gaseous
fuel.

We, GEORGE GORDON BRODIE and JAMES DAMREL PRIOR, of the Eagle Range
and Foundry Company, Limited, Catherine Street, Aston, near Birmingham, in
the County of Warwick, Iron Founders, do hereby declare the nature of our
invention and in what manner the same is to be performed to be particularly
described and ascertained in and by the following statement; -

To regulate the combustion of the range we make an opening at the back of the
hot closet herein before referred to. This opening is either connected with the
boiler flue or with the oven flue above the damper. In the said opening we fit
a plate or valve which may be opened or closed either automatically by the draught
of the chimney, or mechanically by a hand worked rod and knob. When the
plate or valve is arranged to be worked automatically it may be hinged either at
top, bottom or side, and when it is to be worked mechanically the rod and knob
in connection with the door or valve, may be brought to the front of the range
between the front plates of the canopy.

We will now proceed to describe with reference to the accompanying drawings
the manner in which our invention is to be performed.
Figure 1 represents in front elevation a cooking range containing our improve-
ments; Figure 2 represents a front elevation of the hot closet of the range, drawn
to a larger scale, with which hot closet our hood or canopy is combined, portions
of the said hood or canopy being broken away to exhibit parts situated behind the
said hood or canopy; Figure 3 represents a horizontal section of the same showing
the plate rack and part of the hot closet; Figures 4 and 5 represent cross sections
of the hot closet, plate rack and canopy together with the valve at the back of the
hot closet for regulating the draught of the cooking range and for
conveying away the smells from the said range; Figure 6 represents
in front elevation and Figure 7 in side elevation, drawn to a larger scale, the valve
and valve box, fixed at the back of the hot closet; Figure 8 represents in side and
front elevation, drawn to a larger scale, one of the pawls or catches used for holding
the hood or canopy in its open or partly open position.
In Figures 1, 2 and 4, the hood or canopy is represented in its closed position and
in Figure 5 in its fully opened position.
The same letters of reference indicate the same parts in the several figures of the
drawings.
a is the plate rack between which and the top or covering-in plate 6 of the range
is the hot closet for holding and keeping hot, plates, articles of food and the like.
In front of the plate rack and hot closet is the hood or canopy d, d hinged at ², d²
by its top ends to the extreme top of the range; the said hood or canopy is capable
of rising and falling on its hinges, d², d. In the drawing we have represented
the hinged hood or canopy as consisting of two independent parts for convenience
in raising, lowering and adjusting the hood or canopy, but the said canopy or
hood may consist of one long plate or of more than two independent plates. Each
part of the canopy is provided with a jointed handle for raising and lowering it
each part of the canopy being independent of the other part. The canopy is so
hinged that when at liberty to fall it takes the closed position represented in
Figure 4. It will be seen by reference to Figures 2, 4 and 5 that the outer end of
each of the flat plates d, d of the hood or canopy is provided with a sector like
wing dat right angles to the said flat plate. The flange of each wing piece is
made into ratchets at , d with one or other of which ratchets the weighted pawl
or catch e (shown separately in Figure 8) engages, to hold the hood either in its
fully open position Figure 5 or in its intermediate open position. Thus, the hinged
hood can either be raised on its hinges into the horizontal position represented in
Figure 5 or depressed or turned down into the vertical position represented in

page_text: Figure 4; or the hood may be adjusted in an inclined or intermediate position, not
represented. In the highest or fully opened position represented in Figure 5 the
hood d, d is situated about level with the covering in plate 6 and the front of the
hood being entirely removed from the front of the plate rack and hot closet, does
not interfere with the putting of the plates and articles of food into and their
removal from the hot closet. When the hood or canopy d, d is raised into its fully
opened position or into its inclined or intermediate position in front of the hot
closet, it assists in ventilating the kitchen by collecting and carrying away the
smells from the cooking range through the open valve k at the back of the hot
closet to the flue i or oven flue at the back of the range as illustrated in Figure 5,
When the hinged hood or canopy d, d by disengaging its pawls or catches e, by
the handles e, e, from the ratchets, is released it takes its vertical position, as
represented in Figure 4 and closes the front of the plate rack and
converts the space between the said plate rack and top of the range
into a hot closet for receiving plates or dishes and articles of food. The hood or
canopy is prevented from closing beyond the position represented in Figure 4 by
the stop plates f, f against which it strikes. The hinged hood or canopy d, dis
supported in its fully raised position Figure 5 by the dropping of the jointed and
weighted catch or pawl either into the end ratchet or into the middle ratchet d³
in the flange of the quadrant end plated. When the hood or canopy is in its
closed position Figure 4, the catch or pawl e rests on the flange of the end plate

Instead of supporting the hinged hood or canopy by ratchets and pawls or catches
as described and illustrated, the said hood or canopy may be supported by weighted
levers or by weighted chains or cords passing over pulleys or other equivalent
mechanical arrangement; but we have found the arrangement represented in the
drawing to answer well in practice.

To regulate the draught of or combustion in the range we place over the opening g
at the back of the hot closet c, a valve box h carrying the hanging plate or valve k
hinged at and opening inwards; the said valve takes its closed position by
gravity. The said valve box and valve are represented detached drawn to a larger
scale in Figures 6 and 7. The opening at the back of the hot closet communicates
with the fire flue (or oven flue) above the damper, the said flue being in con-
nection with the chimney. The said valve k is opened or permitted to close by the
mechanical arrangement represented; that is, the valve box carries at the front of
the valve a screw box / in which an adjusting screw m works and bears against
the valve. By withdrawing the screw m out of its screw box so as to remove it
from the face of the hanging valve, the latter takes its normal position and closes
the valve box as represented in Figure 4. By advancing the screw m in its screw
box it pushes the valve inwards and opens the valve box as represented in Figure 5
so as to regulate the draught in the range as well as to carry off the smell arising
from the cooking.
The adjusting screw m of the valve is locked in its adjusted position by the lock
nut n provided with a handle or prolongation for turning it.
The adjustment of the valve k may be effected by a long rod brought to the
front of the range and situated between the front plates of the canopy. This
arrangement is represented in Figure the long adjusting rod in connection with
the screw being marked p.
Instead of working the hanging plate or valve k mechanically as represented in
the drawings, it may be opened and closed automatically by the draught of the
chimney in connection with the flue i for regulating the combustion in the range.

page_text: Having now particularly described and ascertained the nature of our invention
and in what manner the same is to be performed we declare that we claim as our
invention of improvements in cooking ranges":-
"
First The addition to or combination with the front of the plate rack of the
range of a hinged hood or canopy capable of a rising and falling motion, which
hood or canopy when in its depressed or fully shut down position closes the front
of the said plate rack and converts the said plate rack into a hot closet for the
purposes and substantially as hereinbefore described and illustrated in the
accompanying drawings.
Secondly-The use of the hinged hood or canopy at the front of the plate rack
for partly or fully opening the front of the hot closet and assisting in ventilating
the kitchen or for fully opening the front of the said hot closet for putting the
plates or articles of food into and removing them from the hot closet substantially
as hereinbefore described and illustrated in the accompanying drawings.
Thirdly The combination with the hinged hood or canopy claimed in the
prior claims of the quadrant shaped ends provided with ratchets which in con-
junction with weighted pawls or catches serve to hold the hood or canopy in its
fully opened or partly opened position substantially as hereinbefore described and
illustrated in the accompanying drawings.
Lastly The use at the back of the hot closet of the range, of a hanging valve
or plate in communication with the fire or oven flue of the range for regulating the
draught of or combustion in the range the said valve and parts connected with it
being constructed and arranged and working substantially as hereinbefore described
and illustrated in the accompanying drawings.
