PROVISIONAL SPECIFICATION.
Improvements in Cooking Ranges.
We, ROBERT HUNTER of the firm of Walker Hunter & Co., Port Downie
Iron Works, Falkirk, Stirlingshire, Ironfounder and JOHN TURNBULL, Foreman
Patternmaker at Port Downie Iron Works aforesaid do hereby declare the nature
of this invention to be as follows:-
This invention relates to cooking ranges or kitcheners of the class which are
convertible from the close fire to the open fire form and it has for its object to
permit of readily extending more or less the length of the open fire flue without
interfering with the free passage of the fire gases under the hot water boiler when
the boiler flue is opened.
In the back covings or chimney piece of the range is formed an opening wherein
is fitted a sliding flue piece composed of two frames one fitted within the other and
adapted to be telescoped so that when the flue piece is pushed back into the
chimney piece it occupies only about half the length to which it is capable of
extending when drawn out. The outer frame is composed of two vertical sides
and a horizontal top and the inner frame is similar but formed without a top and
both are provided with suitable flanged edges or catches to prevent them being
drawn apart when the flue piece is brought forward over the hob.
opening in the back of the range is provided with a door or flap which is pivoted
so that it hangs vertically over the opening and serves to close it when the flue
piece is pushed back and the fire closed but which when the flue piece is drawn
forward to form an open fire is tilted up by the movement of the flue piece and
rests on the inner frame to form a cover for it in rear of the covered outer frame of
the flue piece.
The flue
The boiler flue where it emerges at the hob level is covered by a flap damper
A lever
pivoted to the hob or back strap and having on it a projecting arm.
pivoted to the back part of the chimney flue and operated by a link with a knob
in front serves by acting on the flap damper or on the projecting arm to tilt it
either to open or close the boiler flue.

Improvements in Cooking Ranges.
We ROBERT HUNTER of the firm of Walker Hunter & Co., Port Downie
Iron Works, Falkirk, Stirlingshire Ironfounder and JOHN TURNBULL Foreman
Patternmaker at Port Downie Iron Works aforesaid 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 relates to cooking ranges or kitcheners of the class which are
convertible from the close fire to the open fire form and it has for its object to
permit of readily extending more or less the length of the open fire flue without
interfering with the free passage of the fire gases under the hot water boiler when
the boiler flue is opened.
The invention is illustrated in the accompanying drawings in which
Figure 1 is a vertical section of part of a cooking range showing the fire flue

page_text: Figure 2 is a similar view showing the fire flue drawn forward, and
Figures 3 and 4 are respectively a plan and front elevation of the flue piece.
In the back covings or chimney piece A of the range is formed an opening B
wherein is fitted a sliding flue piece composed of two frames C, C¹ the one fitted
within the other and adapted to be telescoped so that when the flue piece is pushed
back into the chimney piece as shown at Figure 1 it occupies only about half the
length to which it is capable of extending when drawn out to the position shown
at Figure 2. The outer frame is composed of two vertical sides C C and a hori-
zontal top c and the inner frame C₁ is similar but formed without a top and both
are provided with suitable flanged edges or catches c¹ c² to prevent them being
drawn apart when the flue piece is brought forward over the hob. The flue
opening in the back of the range is provided with a door or flap D which is pivoted
so that it hangs vertically over the opening B and serves to close it when the flue
piece is pushed back and the fire closed but which when the flue piece is drawn
forward to form an open fire is tilted up by the movement of the flue piece and
rests on the inner frame C¹ to form a cover for it in rear of the covered outer
frame C of the flue piece.
The boiler flue where it emerges at the hob level is covered by a flap damper E
pivoted to the hob or back strap and having on it a projecting arm e. A lever F
pivoted to the back part of the chimney fue and operated by a link F¹ with a
knob fin front serves, by acting on the flap damper or on the projecting arm e to
tilt it either to open or close the boiler flue."
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 :-
1. A cooking range having a telescopic fire flue and connections, constructed,
arranged and combined substantially as described with reference to the annexed
drawings.
2. In a cooking range a telescopic fire flue composed of two frames fitted to
slide on the hob and used in conjunction with a door or flap over the flue opening
substantially as and for the purpose set forth.
Dated this Thirty-first day of October 1892.
