PROVISIONAL SPECIFICATION.
Improvements in and connected with Cooking Stoves.
SAMUEL TERRILL and THOMAS ROGERS of West End Redruth in the County of
Cornwall Hot Water Engineers and Stove Manufacturers do hereby declare the
nature of their invention for IMPROVEMENTS IN AND CONNECTED WITH COOKING
STOVES to be as follows:-
A double slide door to the fire place, with the alternative of letting in or stopping
draught, consisting of two sliding plates with holes in them capable of producing a
great heat without burning the front bars of the stove. When a great heat is not
required the draught can be sent over the fire, by closing the bottom slide and opening
the one at the top, thereby saving a considerable amount of fuel.
The fire place has a moveable bottom which is raised or lowered by parallel action,
worked by levers kept in a perpendicular position by two upright slides, so as to
The
produce a large fire for cooking purposes or a small fire as may be necessary
grating at the bottom is moveable, and has a flange all round which covers the frame
on which it rests so as to prevent the heat coming in contact with the frame.
The front bars of the stove are fixed to a frame which is kept in position by four
catches, two at the bottom and one on each side, and can easily be replaced when
required.
The fender is constructed with an angle rim, the warming rest being wholly on the
outside of the rim, leaving the whole of the inside free for catching ashes from the
fire place The body is riveted around the rim underneath the top.
The brackets on which the rods supporting the plate rack rests, are fixed to the
jamb by the top and bottom, leaving the inside of the bracket free for adjusting the
rods, the brackets projecting inwards and upwards from the rim which is on the out-
side, the rods cannot ship over, and preventing the rack in case of accident falling
lower than the bottom of the bracket.
The damper frame is constructed with a semi circle upwards and downwards from
the centre of the frame, to enable a sweeping brush to be used higher and lower in the
flue, on the damper being removed.
The skirtings jambs and frames are constructed with reeded panels which has the
advantage of being more easily cleaned than those now in use. The jambs have side
pieces and stand out from the front of the stove, thus saving the paint or paper on the
walls at the sides of the stove from being soiled.

COMPLETE SPECIFICATION.
Improvements in and connected with Cooking Stoves.
We, SAMUEL TERRILL and THOMAS ROGERS, of West End, Redruth, in the
County of Cornwall, Hot Water Engineers and Stove 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

COMPLETE SPECIFICATION.
Improvements in and connected with Cooking Stoves.
We, SAMUEL TERRILL and THOMAS ROGERS, of West End, Redruth, in the
County of Cornwall, Hot Water Engineers and Stove 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
Our invention relates to improvements in and connected with cooking stoves; and
nas more especial reference to
1. Improved means for regulating the draught through the fire place
2. Improved means for regulating the depth of the fire place:
3. Improved detachable range or bars:
4. Improved combined fender and warming rest
-

page_text: 7. Improved stove jambs
In order that our said invention, and the means by which the same is to be carried
into practical effect may be thoroughly understood, we will now describe them in
detail, referring in so doing to the accompanying drawings which are to be taken as
part of this specification and read therewith.
Fig. 1 is a front elevation of a cooking stove embodying the several features of our
invention.
Fig. 2 is a vertical section on the line A-B of Fig 1.
Fig. 3 is a vertical section on a larger scale of the improved double slide door.
Fig. 4 is a front elevation of the inner face of our improved detachable range
or bars.
Referring to Figs. 1, 2, and 3, our improved double-slide door consists of a suitable
frame c pivotted on the stove front at d, d.
In this frame are formed two series of openings f, f'; and two slides g, g', provided
with openings h, ³, are fitted so as to slide backwards and forwards, independently of
each other, in front of the said two series of openings In one position of either slide,
the openings in the frame will be closed by the solid metal between the openings in
the slide, while in the opposite position of the same slide, the openings in both slide
and frame will coincide, and any intermediate position will give a correspondingly
intermediate amount of clear way, after the manner of, what is known as, a hit-and-
miss ventilator. Fig. 1 shews the top slide closed, and the bottom slide open, while
Fig. 3 shews the bottom slide closed, and the top one open.
In the ordinary cooking stove with a closed fire and hot plate over, has been the
custom to provide a door about a third of the depth of the fire place; and hinge it to
one side, close under the hot plate. When the door has been wide open, the draught
has been through the bed of fuel equally at all levels; and closing the door has had
the effect of compelling all the draught to pass into the fuel below the door, thereby
rapidly increasing the heat of the fire with a corresponding wear of the bars
there has been no provision for stopping a draught from the front through the lower
levels of the bed of fuel.
But
Now, according to the first part of our invention now under description, the
draught from the front through the fuel can be regulated exactly as required, by
merely adjusting the positions of the slides g, g'. If the cook wants a strong fire,
she will close the top slide, and open the bottom one; if a still stronger one, she
will close both slides; but if, on the other hand, the fire may be allowed to go
down, the bottom slide will be closed, and the top one opened, with the result
that the draught will pass over the fuel So perfect is the control over the fire
which our invention places in the hands of the cook, that she is enabled to carry
out her cooking operations entirely to her and her employer's satisfaction, and at
the same time effect a considerable saving in fuel as compared with older con-
structions of stoves.
The second part of our invention is illustrated in Figs 1 and 2. 2 is an open
rectangular frame, rather less in area than the fire place, in which it is adapted
to move freely up and down. It is shewn in end elevation by the dotted lines
of Fig. 2. are legs fast to the frame at either end; and are their guides,
fixed to the respective sides of the ash-pit. k is the loose bottom grate adapted to
lie upon the frame i
It differs from the usual pattern of barred bottom grate
in being made with an all round flange The effect of this flange, in conjunc-
tion with the margin of the bottom grate, is to preserve the frame from the
destructive action of the fire.
The mechanism, by means of which the position of the bottom-grate k is adjusted,
consists of a pair of levers 1 1, having a common fulcrum in a shaft m carried in
bearings m on the stove-front, and of a pair of links n, n, pivotted to the outer
ends of the said levers and to the ends of the frame i
The shaft m terminates in squares o, o'. A suitable wrench is provided by which

page_text: the square o can be gripped and the shaft turned in either direction. p is a detent
made like a wrench and fastened by a few links of chain to the stove front. When
the shaft has been turned as far as required, the detent is slipped onto the square o to
prevent it turning back
The third part of our invention is illustrated in Figs. 2 and 4.
9, the bars; and g³, catches adapted to engage with projections
9 is the frame ;
on the respective
sides of the fire-place. Equivalent devices for holding the frame in position may be
adopted.
The fourth part of our invention is illustrated in Figs 1 and 2. is the under-
grate ash pan; and r³, a capacious angle rim, constituting our improved fender and
having its own ash catcher. The warming rest is wholly outside the fender front
so that no cinders can fall upon anything "put down to the fire."
The fifth part of our invention relates to improvements in the construction of the
plate-rack, and is illustrated in Figs. 1 and 2. s, s are brackets hxed to the jambs.
Each one has several rests ¹ opening upwards towards the respective jambs, and
adapted to receive rods t upon which the rack u rests. It will be gathered from an
examination of the figures that the rods cannot fall out of their rests in any direction,
nor the position of the plate-rack be affected while either hurriedly removing dishes
or piles of plates from it, or carelessly dasting it.
The sixth part of our invention is illustrated in Figs. 1 and 2.
The damper
frame V is constructed with semicircles u, v, to allow of a flue brush being worked
into the flue further in both directions than it could be if the opening were
rectangular.
The seventh part of our invention relates to improvements in connection with the
Jambs w, w, of the stove.
According to our present invention, the jambs are part of the stove, being firmly
screwed thereto and standing with it; and can, if necessary, be utilised as a mantel
piece by placing a shelf on the top.
Having now particularly described and ascertained the nature of our said inven-
tion, and in what manner the same is to be performed, we declare that what we
claim 15.
1. The combination with the range of a pair of slide ventilating devices indepen-
dently adjustable in respect of their capacity for passing air, as set forth.
2. The combination of flanged bottom grate, frame adapted to rise and fall, shaft,
link-and-lever device, and devices for moving and locking the shaft, as described with
reference to the accompanying Figs. 1 and 2.
3. The combination of detachable frame and bars as described with reference
to Fig. 4.
4. The combination of fender and warming rest, as described with reference to the
accompanying Figs 1 and 2.
5. The improved plate-rack brackets, having their several rests opening inwards
and upwards towards the sides of the stove, as described with reference to Figs. 1
and 2
6. The combination with the damper frame of openings by which the flue brush
can be worked into the flue further in both directions.
7. In cooking stoves, fixing the jambs to the stove, as set forth.
