Improvements in Cooking Ranges.
We DAVID COWAN, Manager for Carron Company, of Kerschill, Falkirk in
the County of Stirling, JOSEPH DANIEL DUCKETT of 7 Danson Terrace,
Carron, Foundry Works Manager, and PETER ALLAN of View House, Carron,
in the County of Stirling, Draughtsman, do hereby declare the nature of this
invention to be as follows
-
This invention has for its object, 1st. The simplification of the working parts
and the reduction of the number of movements required to be made in converting a
close into an open fire range and vice versa, the transition with the improved
apparatus being effected by the use of one hand only and by one movement and,
2nd. The construction in an improved manner of the front plate of the range over
the fire, which corresponds to what is known as a falling bar, usually pivotted in
the front grating of a cooking range or stove.
In carrying out the first part of our invention we employ two side wings or
plates each being provided with a crank arm and pin at its lowest point, and a top
or covering plate. all of which are hinged or pivotted in the front plate of the flue
pipe, or in the plates known as "covings" situated above and in rear of the fire.
The movable plate which covers the fire, known as the fire cover, is provided with
two projecting spurs or cranks on each side the rearmost pair of which are so
arranged that when said fire cover is pushed back, they pass under and clear of
the crank arm and pin attached to each of the side wings, the pair of projecting
spurs placed in frout of those already referred to impinging on said crank arms
and pins and by their means the side wings are gradually forced open, until they
are parallel with each other or nearly so, their movement at the same time
raising the top or covering plate to a sloping or horizontal position immediately
over and in rear of the fire. When the fire cover is pulled forward its rearmost
pair of spurs strike the said crank arms and pins, causing the side wings to close
inwards and the top or covering plate being thus relieved of its supports falls down
to an almost vertical position in front of them. The projecting spurs are arranged
to open and shut both side wings simultaneously or to open one a little in advance
of the other if required.
The second part of our invention relates to an improved device in that part of
the front plate of a cooking range or stove situated immediately over the fire, and
it consists of a movable part provided with short feet at each end, said feet acting
as guides and working in a slot prepared for them at each side of the fire opening.
When this movable part of the front plate is level with the hob, the, feet or guides
rest, in a notch near the upper extremity of the slot, but when disengaged the
movable part slides or falls down in an almost perpendicular manner until the feet
or guides rest in another notch or ledge at the lower end of the slot. When in
this position the removable part forms a shelf upon which cooking utensils can be
placed in close proximity to the fire and it is raised or lowered at will with an
ordinary fire iron.

Improvements in Cooking Ranges.
We, DAVID COWAN, Manager for Carron Company of Kerschill, Falkirk in
the County of Stirling, JOSEPH DANIEL DUCKETT of 7 Danson Terrace,
Carron, Foundry Works Manager, and PETER ALLAN of View House, Carron,
in the County of Stirling, Draughtsman, 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:-
This invention has for its object first the simplification of the working parts and
the reduction of the number of movements required to be made in converting a
close into an open fire range and vice versa the transition with the improved
apparatus being effected by the use of one hand only and by one movement and
second the construction in an improved manner of the front plate of the range over
the fire and which corresponds to what is known as a falling bar usually pivotted
in the front grating of a cooking range or stove.
As seen in vertical section of part of a cooking range at Figure 1 in part plan
and part horizontal section at Figure 2 and in part front elevation at Figure 3 of
the annexed drawings we employ to carry out the first part of our invention two
side wings or plates a cach being provided with a crank arm and pin b at its lowest
point and a top or covering plate e all of these being hinged or pivotted on the
front plate d of the flue pipe or in the plates known as
covings situated
above and in rear of the fire the wings being also pivotted at their lower ends in
the joining plate m of the hob.

The movable plate e which covers the fire and is known as the fire cover rests
upon inclined guide flanges or rails attached to the hob plate m' and it is
provided with two projecting spurs ff on each side. When the cover e is pushed
back to form an open fire it slides down the guide flanges or rails kk passing
beneath the joining plate m as shewn in dotted lines and the rearmost pair of
spurs is so arranged as during this movement to pass under and clear of the
crank arms and pins attached to the side wings a whilst the pair of projecting
spurs in front impinge on or come in contact with the said crank arms and pins
and by their action thereon cause the side wings a to be gradually swung open
until they are parallel with each other or nearly so the outward movement of the
wings at the same time raising the top or covering plate to a sloping or horizontal
position immediately over and in rear of the fire. When the fire cover e is pulled
forward to form a close fire range as at the upper part of Figure 2 its rearmost
pair of spurs strike the crank arms and pins causing the side wings a to swing
inwards and the top or covering plate e being thus deprived of its supports falls
down to an almost vertical position in front of them as at Figure 3. The
projecting spurs ƒ ƒ are arranged to open and shut both side wings a simul-
taneously or they may be arranged to open one a little in advance of the other if
required.
The second part of our invention relates to an improved device in that part of
the front plate of a cooking range or stove situated immediately over the fire and it
consists of a movable party provided with short feet h at each end, said feet acting
as guides and working in slots i prepared for them at each side of the fire opening.
When this movable part of the front plate is level with the hob the feet or
guides rest in notches or on shoulders near the upper extremities of the slots i but
when disengaged the movable part slides or falls down in an almost perpendicular
manner as seen by the dotted lines at Figure 1 until the feet or guides rest on the
lower end of the slots. When in this lowered position the removable part a forms a
shelf upon which cooking utensils can be placed in close proximity to the fire and
it is raised or lowered at will with an ordinary fire iron. The vertically movable
party may also be used in conjunction with cover plates e of usual construction.

page_text: 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 is:-
J
1. In a convertible close and open cooking range the combination of a fire cover
plate having spurs ff at each side with side wings a having crank arms and
pins at their lower ends acted upon by the spurs so as at one movement to
open or close the wings and to raise or lower the cover c substantially as described
with reference to the drawings annexed
2. In a convertible close and open cooking range the combination with the cover
plate e of a vertically movable part g constructed and operating substantially as
and for the purpose set forth with reference to the accompanying drawings.
