Improvements in Cooking Ranges.
We, ROBERT HUNTER of the Firm of Walker Hunter and Company, Port
Downie Iron Works, Falkirk, Stirlingshire, Ironfounders, and JOHN TURNBULL,
Foreman Pattern Maker at Port Downie Iron Works aforesaid, do hereby
declare the nature of this invention to be as follows:-
This invention, which relates to cooking ranges of the type which are convertible
from the open to the close fire form and vice versa has for its object the provision
of a sliding flue piece which is adapted to be drawn forward over the hot plate in
making an open fire and when pushed back in closing the range to fit into the
jamb coves or back of the range or in the flue pipe without closing the boiler or
other flue opening to the chimney, the flue piece being also designed to automatically
open and close by its sliding movement, the passage through it from the fire
opening to the chimney.
The improved flue piece is composed of a long box flue sliding on the hot plate
and having vertical sides formed integral with or attached to a horizontal top
plate covering or closing in the forward end of the flue piece whilst the rear
position is open at the top and is covered when the flue piece is drawn forward by a
plate pivoted to the sides of the flue piece or hinged to the fixed cover plate. When
the flue piece is pushed back in closing the range the pivoted cover hangs from its
hinge or pivots assuming a vertical or oblique position and leaving the upper rear
portion of the flue piece open for the passage of the fire gases from the boiler or
oveu flue to the chimney whilst when the flue piece is drawn forward in opening
the range the pivoted part of the cover is tilted up by means of guiding supports
or cam pieces secured to the hob behind the coving or at the back of the range and
thereby retained in the horizontal position in which it covers the open rear part of
the flue piece. Within the flue piece and resting on the hob is a plate supported
at a slight inclination by ribs or webs on the underside and having projections at
the lower front ends adapted to engage with catch pieces on the inner walls of the
flue piece. This plate when the flue piece is pushed back is tilted up by contact
at its rear end with curved or inclined guides formed on the front of the supports
for the pivoted cover plate so that it attains a vertical position in which it closes
the opening through the coving to the chimney, and when the flue piece is drawn
forward this plate is caught at its lower edge and pulled forward until it lies on the
hob leaving the opening through the coving free.

Improvements in Cooking Ranges.
We, ROBERT HUNTER of the Firm of Walker, Hunter and Company, Port
Downie Iron Works, Falkirk, Stirlingshire, Ironfounders, and JOHN TURNBULL,
Foreman Pattern Maker 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, which relates to cooking ranges of the type which are convertible

page_text: from the open to the close fire form and vice versa has for its object the provision
of a sliding flue piece which is adapted to be drawn forward over the hot plate in
making an open fire and when pushed back in closing the range to fit into the
jamb coves or back of the range or in the flue pipe without closing the boiler or
other flue opening to the chimney, the flue piece being also designed to automatically
open and close by its sliding movement, the passage through it from the fire opening
to the chimney.
C
The invention is illustrated by the accompanying drawings, Figure 1 being a
vertical section shewing the range in close fire form, Figure 2 a front elevation of
same partly in section, Figure 3 a vertical section shewing the range in open fire
form and Figures 4 and 5 vertical sections in close and open fire forms respectively
of a modification thereof. Referring to Figures 1, 2 and 3, the improved flue
piece A is composed of a box flue sliding on the hot plate B and having vertical
sides a formed integral with or attached to a horizontal top plate covering or
closing in the forward end of the flue piece A whilst the rear portion is open at
the top and is covered when the flue piece is drawn forward by a plate c pivoted
to the sides a of the flue piece or hinged to the fixed cover plate b.
When the
flue piece A is pushed back in closing the range the pivoted cover c hangs from its
hinge or pivots assuming a vertical or oblique position and leaving the upper rear
portion of the flue piece A open for the passage of the fire gases from the boiler
or oven flue to the chimney C whilst when the flue piece is drawn forward in
opening the range the pivoted part of the cover is tilted up by means of guiding
supports or cam pieces D secured to the hob or hot plate 13 behind the coving or
at the back of the range and thereby retained in the horizontal position in which
it covers the open rear part of the flue piece. Within the flue piece A and
resting on the hob B is a front plate E supported at a slight inclination by ribs
or webs d on the underside and having projections at the lower front ends
adapted to engage with the lower edges of the part g of the flue piece to close it.
This plate E when the flue piece is pushed back is tilted up by contact at its rear
end with curved or inclined guides h formed on the front of the supports D for
the pivoted cover plate c so that it attains a vertical position in which it closes
the opening through the coving to the chimney C and when the flue piece A is
drawn forward it permits the lower edge of the front plate E to slide forward
until it lies on the hob leaving the opening through the coving free, a stop i
being formed on the cam piece D to engage with a catch on the plate E and
prevent the plate from sliding too far forward. To ensure the casy working of
the flue piece A ribs & are cast upon the inner faces of the sides a which act against
guiding ribs cast on the cam piece D.
Under the modification shewn by Figures 4 and 5, the hinged part c of the
flue A is dispensed with and the plate E is raised by being forced against a cam
piece F secured or cast on the hot plate B.
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 :-
In a convertible cooking range a sliding box flue piece having a pivoted cover
at its rear portion and a plate adapted to open or close the passage through the
flue piece and means for operating them by the movement of said flue piece,
substantially as described with reference to the annexed drawings.
