1 JOHN EYRE RUSSELL of the firm of Robert Russell & Sons, Peel Foundry Derby
in the County of Derby Stove Grate and Kitchen Range Manufacturers do hereby
doclare the nature of my invention for IMPROVEMENTS IN COOKING RANGES to be as
follows
-
My invention chiefly refers to open fire Cooking Ranges but may also be applied to
close fire Ranges or those known as Leamington Ranges, and consists of an improved
bonnet or hood, placed on the top of the range at the back of the fire, also an improved
means of attaching the fall bar so that in case of breakage it may readily be replaced
without disturbing the other parts of range. Also an improved side plate or oven
cheek for more effectually heating the oven & preventing the accumulation of ashes in
the draught hole, also for forming part of the flue under the oven by extending the
lower portion of the cheek below the fire. In carrying out the first part of my
improvement, I provide a frame of cast or wrot iron, with projections or notches up
each side, I also provide a cast or wrot plate which may have a projecting hood, this
plate has a stud or projection at the back, which when the plate is raised or lowered,
serves as a ledge or stop to fit into the notches at the side of the frame, so that the
plate with hood can be raised or lowered to any height, thus preventing the smoke
from the fire escaping into the room, and also when the hood is lowered, increasing
the draught of fire, I further provide if necessary, two loose doors or wings, which fit
on each side of the frame, so as to more effectually enclose the opening under the
hood or plate.
To carry out the second part of my improvement the improved means of replacing
or fitting the fall down bar of range, I cast in each end of the fall bar, a strong cast
or wrot pin, and in the fire bar frame I cast at each side, an oblong hole with the
front portion of hole open. When the fall bar is in its position between the fire frame,

page_text: I screw or otherwise attach, a loose piece of metal in front of the open oblong holes,
thus preventing the fall bar from coming out of its position..
The third part of my improvement, relates to the cheek or projecting plate at the
side of oven, to carry out this portion of my improvement, I provide a strong cast or
wrot iron check or plate, having an horizontial oblong hole bevilled upwards so that
any ashes getting into this hole will fall into the fire again, & the bevilling of this hole
more effectually conducts the heated gasses over the top of oven, the lower portion of
the cheek has or may have a grating, or other holes so that the heat from the lower
portion of fire may pass underneath the oven. I also carry a portion of this cheek or
plate below the bottom of the fire so as to form one side of the oven flue underneath
the fire, thus dispensing with brickwork, or a seperate loose plate as usually fixed to
ranges having a down draught flue.

page_text: I, JOHN EYRE RUSSELL of the firm of Robert Russell & Sons Peel Foundry, Derby,
in the County of Derby Stove Grate and Kitchen Range Manufacturers 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 :-
My invention relates to improved appliances which are intended, chiefly, for use in
connection with "open fire cooking Ranges" but which appliances are not limited,
exclusively to such Ranges, one or more of such agents being equally applicable to
"closefire Ranges
""combined open & Close fire Ranges" and to those commonly
called "Leamington Ranges."
These improvements consist,
First, of a moveable or adjustable Hood or Bonnet, at the back part of the Range,
which is designed for use in connection with the fire; also in the mode of adjusting it
as well as in the means employed therefor.
"
to the frame,
Secondly, of a novel method and means for attaching the "fall bar
which contains, or constitutes, part of the fire bars of such Ranges as I have before
named.
Thirdly, in the means or agent employed for forming, and defining the limits of the
flue between the fire and the oven, and of that which extends beneath the oven; this
agent is a perforated metal side plate or cheek placed between the fire and the oven
and elongated, vertically, below the fire to a suitable depth beyond the level of the
oven bottom.
The first of these improvements may be thus particularised; I provide an upright
metal frame (either cast or wrought) consisting of two upright side flanges and a
lintel across the upper part of them which unites the two side flanges but leaves the
top open, there being no roof plate to the frame.
This frame is suitably constructed for attachment at the back part of the Range by
uniting it there, either to the wall or the metal plates which (in various forms) commonly
fill up the Cove or recess in which the Range is placed; or which otherwise compose
the back of the Range.
The locality in which this frame is attached is immediately opposite to the back of
the fire and with its base upon, or on the level of, the Hob or Hobs of the Range.
On the inner side of each upright flange (or jamb) I provide a rack, consisting of
small notches, teeth or catches for purposes of support.
This metal frame is designed chiefly as a guiding frame, within which to manipulate
a moveable Hood. This hood is provided with an upright plate which fits loosely
within the vertical jambs of the frame and is moved up and down behind the lintel,
where suitable ledges are provided for compelling it to move only in vertical planes;
the hood, which is attached to the lower part of this plate, is broader than the frame

page_text: and is retained upon the surface of it as it is raised or lowered. Behind the hood I
attach one or more projecting studs or pins for insertion within the side racks and by
these means I make the Hood capable of adjustment at any required elevation. The
upper, vertical, plate of this moveable hood may be projected upwards beyond the top
of the lintel or the hood may be entirely removed from the frame in order to afford
access to the flue for cleaning, building, repairing or other purposes.
The second of these improvements is capable of several variations although its
essential character is the same in any of the variations. It is an adjustable cap or
cover-plate, for closing or covering each (or either) socket in which the pins of the
Range "fall bar" revolve.
Within each (or either) side flange of the Range fire bars (or their frame) I provide
an oblong, oval, or round recess in which the pivots of the fall bar are placed and I
cover each such open recess with a metal cap, screwed or otherwise attached to the
surrounding metal work; thereby converting such open recess into a closed socket.
These recesses, when oblong in form, are preferably vertical but may, if required be
arranged horizontally; they may be either on the front or face of the fire bars and
frame or on the back of it although preferably on the front.
The pins just referred to are attached to the outside frame of the fall bar and may
be cast in or with the fall bar or may be otherwise attached to it. As an alternative
plan, or a variation of the same plan instead of the pins being attached to the fall bar
and the sockets provided in the fire bar frame, the sockets may be in the fall bar and
the pins attached to the fire bar frame; in which (latter) case the cap or caps for
covering the sockets are attached to the fall bar and not to the fire bar frame or
surrounding metal work. By means of this cap or covering plate for each such socket
I have simplified the process of removal and replacement of the fall bar for purposes
of repair or examination.
The third of these improvements is, as before stated, for defining, or partially
defining the depth of the flue underneath the oven. It serves, also, to form a flue
between the fire and the oven, as well as a useful agent, for aiding the circulation of
heat above and below the oven, together with other useful purposes such as, preventing,
by its peculiar form, the accumulation of coals or ashes in the aperture leading from
the fire to the top of oven. The appliance which I employ for these several purposes
is a strong cast (or wrought) Iron plate which forms the side of the fire.nearest to the
oven. The centre part of this plate, which adjoins the fire is perforated in the manner
of a grating and affords means for the heat from the fire to pass directly to the flue
under the oven. The upper part of the plate is bevilled or sloped until it unites with
the roof plate of the oven, and by this sloping form the heated gasses from the fire
pass more freely to the top of the oven and the ashes and coals are induced to slip
downwards into the fire instead, of choking up the opening formed between the
hot-plate and the top of this cheek.
The extreme lower portion of this cheek is carried below the bottom of the fire and
oven to a suitable depth for determining the depth of the flue under the oven.
The following diagrams will better illustrate this invention and enable it to be more
thoroughly understood and more readily carried into effect.
Fig. 1 is a perspective view of an open fire cooking Range: shewing the application
of the adjustable hood as herein described. The parts marked M. are shewn without
the usual fittings as the latter are not essential to the purposes of the present
description. The reference letters throughout these diagrams, are the same for
corresponding parts wherever they occur.
Figs. 2, 3, 4, 5, 6 and 7 are perspective views and elevations of the several parts of
the adjustable Hood and its fraine and are fully described thus,
Fig. 2 is a perspective view of the adjustable hood or canopy which can be raised or
lowered and fixed at any suitable or required elevation: D is the upright plate, before
described which fits loosely behind the lintel F and within the upright jambs N. In
this illustration B is one of the projecting studs or pins for adjustment within the rack
marked A.
Fig. 3 is a perspective view of the frame, in, and upon which, the hood shewn in

page_text: figure 2 is adjusted. The upright jambs are marked N and the lintel F. The letters E
indicate flanges for restraining the upright plate D in its movements up and down,
and C indicates the space in which the said plate moves. K and L are members for
automatically adjusting the frame to the adjacent parts of Range.
Fig. 4 is a side section and elevation combined of the adjustable hood.
Fig. 5 is a side section and elevation of the canopy frame (Fig. 3) shewing an open
space, or astragal, C, through which, on each side of frame, the upper part (D) of the
canopy projects and slides: when these appliances are in use the flanges E affording
important helps in the formation of these astragals. The projection, L, is for purposes
of adjustment to other parts of Range.
Fig. 6 is a side elevation of the frame and part of the Hood; the other part of hood
being in its proper position behind or within the frame. K is for purposes of
adjustment to other parts of Range.
Fig. 7 is a side elevation of the Hood.
Fig. 8 is a perspective view of the fire bars removed from the Range and shewing
the cap G detached. H indicates the oblong slot (in vertical position) or hollow
cavity in which the pin J revolves when the cap G is placed in front of it and secured
to the stove front as shewn in Fig. 1. One cap only is shewn in these illustrations
(Figs. 1 and 8) although two may be used if required, one on each side of the Range.
I wish distinctly to state that I do not claim as any part of my invention the
application of a moveable Hood such as herein described & which is adjustable at
various elevations within a framework, to Register Grates, but limit my claim
distinctly to its use for open fire cooking Ranges, close fire cooking Ranges, and
combined close and open fire cooking Ranges, whether the said Ranges be heated with
Coal, Coke, Gas or other agents.
I also desire to state that I do not claim as my invention either the character of the
fire check herein described nor the particular form of said cheek: inasmuch as certain
parts of it are well known and my improvements therein are not easily definable or
separable from those parts which are well known I have decided to exclude this item
from the invention for which I ask that a patent may be granted to me.
Having now particularly described and ascertained the nature of my invention and
in what manner the same is to be performed, I declare that what I claim is,
First, in a cooking apparatus, such as herein described, the use of a moveable and
adjustable Hood and Frame, such as herein described, (the same being constructed,
and operated, substantially as herein described and shown) and for the purposes set
forth herein.
Second, in a cooking apparatus such as herein described the use of one or more caps
for enclosing the pins upon which the fall bar revolves and for the method
(or methods) herein described and shown for rendering such fall bars removeable.
Third, in a stove of any kind, whether for cooking or Heating purposes, the method,
and means, herein described, and shewn in Figs. 1 and 8, for rendering a part of such
fire bars removeable, whether the said part consists of the upper, lower or middle ribs
of the fire bars.
