IMPROVEMENTS IN KITCHEN RANGES to be as follows:
Year: 1885

page_text: We, ROBERT HUNTER of the firm of Walker Hunter and Company, Iron
Founder, and JOHN TURNBULL, Foreman Patternmaker, both of Port Downie
Iron Works Falkirk in the County of Stirling, do hereby declare the nature of
our invention for "IMPROVEMENTS IN KITCHEN RANGES to be as follows:-
"
This invention which relates to kitchen ranges consists of an improved arrange-
ment of folding or collapsable fire flue so fitted in connection with the fire cover
that when opened out on the lifting of the cover an open fire range is forined, and
when closed down and the fire cover replaced a close fire-range is formed.
In constructing the improved kitchen range, the part of the hob immediately.
behind the fire cover is cut away in a line with the cover, and the parts of the
range are bound together by a lower back strap. In this space are fitted two
plates or flaps which are pivotted or hinged at their outer edges to the hob in such
wise that they may lie horizontally with their inner edges meeting together or
fitting close to a central fixed plate, or they may be folded out on their pivots to
rest vertically or nearly so. In this latter position they form the sides or walls of
a flue, the top of which is formed by lifting the fire cover to rest on their upper
edges. A flue opening is cut out of the cove plates or a movable plate with a flue
opening in it is secured to the cove plate and through this opening pass the hot
gases which rise from the fire and traverse the flue. In order to close the flue
opening when the fire cover is replaced and the flue walls folded down, a broad
flange or a vertical plate is cast or fitted on to each of the hinged plates forming
the flue, each of such vertical plates being of a size adapted to cover half of the
Blue opening. The rear pivots of the folding flue are fitted in the movable plate,
so that by removing such plate, the folding flue plates may be withdrawn if
required for repair. The fire cover is formed with projecting lugs fitting under
the flue plates, so that when converting the range from the close fire form to that
of an open fire, the lifting of the fire cover effects the canting of the flue plates to
the vertical position.

We, ROBERT HUNTER of the firm of Walker, Hunter and Company, Iron
Founder, and JOHN TURNBULL, Foreman Patternmaker, both of Port Downie
Iron Works, Falkirk, in the County of Stirling, 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, which relates to kitchen ranges consists of an improved arrange-
ment of convertible folding fire flue so fitted in connection with the fire cover that
when opened out on the lifting of the cover an open fire range is formed and when
closed down and the fire cover replaced a close fire range is formed.

In the accompanying drawings which illustrate our invention figure 1 is a front
elevation of a kitchen range having our improved fire flue arrangement applied
thereto, figures 2 and 3 are respectively a plan and an elevation to a larger scale,
of the parts of the range in connection with the fire flue and figures 4 and 5 are
sections at the lines X - X and Y.- Y respectively in figure 1. In the
improved kitchen range the part of the hob A immediately behind the fire cover B,
is cut away in a line with the cover and the parts of the range are bound together
by a lower back strap C. In the space thus formed over the back strap are fitted
two plates or flaps D, D, which are pivotted or hinged at their outer edges by pins
or projections d, passing under snugs e, on the back strap in the line of the hob in
front and through the coving at the back or under a movable plate E, which forms
the coving at this part. The plates D, D, may lie horizontally with their inner
edges meeting together, or fitting closely up against a central fixed plate which
may be fitted to rest over the back strap, and they may be folded out on their
pivots to stand vertically or nearly so. In this latter position they form the sides
or walls of a flue F, as shown in figure 1, the top of which is formed by lifting the
fire cover to rest on their upper edges or on check strips f, formed on their inner
sides near the edges. A flue opening G, is cut out of the cove plates or in the
movable plate E, and through this opening G, pass the hot gases which rise from
the fire, and traverse the flue when in the open position. When the flue is closed
and the fire cover replaced the hot gases pass in the usual way through the oven
flues at the side of the fire. For the purpose of closing the flue opening G; when
the fire cover B, is replaced and the flue walls folded down, a broad flange or
vertical plate D¹, is cast or fitted on to each of the pivotted plates D, forming the
flue, the vertical plates D¹, being each of a size adapted to cover half of the flue
opening G, as is shown in figures 2 and 3 which represent one of the plates D,
folded down to the closed horizontal position and the other raised to the vertical
position in which it is maintained by the flange D¹, resting on the hob. The rear
pivots of the folding flue are fitted in or under the movable plate E, which is
secured by screws to the coving so that by undoing the screws and removing said
plate E, the folding flue plates D, D¹, may be withdrawn if required for repair.
The fire cover B, rests in the usual checks a in the hob and on it is formed a
projecting lug B¹, extending over a recess C¹, in the back strap C, and under the
flue plates D, D, in such a position that when the fire cover B, is lifted to convert

page_text: the range from the close fire form to the open fire arrangement, the lug B¹, lifts
and tilts the plates D, to the vertical position in which they form the side walls of
the flue F, the close fire being thus converted into an open fire range by a single
movement in raising the fire cover.
Having now particularly described and ascertained the nature of our said
invention and in what manner the same is to be performed we declare that what
we claim is
(1.) The combination of parts constituting the improved convertible or open
and close fire flue arrangement, for kitchen ranges, substantially as herein described
with reference to the drawings annexed.
•
(2.) In a convertible fire range the pivotted plates or flaps D, formed with wings
or flanges D' and adapted when in the open position to form the walls of an open
fire flue, and in the closed position to cover the flue opening in the coving, sub-
stantially as herein described with reference to the drawings annexed.
(3.) In a convertible fire range of the kind herein described a fire cover formed
with a projecting lug or lugs extending under and adapted to tilt the pivotted
plates or flaps D, D, to form the side walls of an open flue in the act of raising the
fire cover itself substantially as described with reference to the drawings annexed.
