PROVISIONAL SPECIFICATION.
Improvements in Cooking Ranges.
I, HUGH STEVEN of the firm of McDowall Steven & Co., Ironfounders, Milton
Iron Works, Glasgow, do hereby declare the nature of this invention to be as
follows:-
This invention has for its object to render cooking ranges more readily convertible
than hitherto from the open to the close fire form and it consists in fitting within
the ordinary vertical uptake or flue piece at the rear of the fire a damper plate
pivotted in the manner of a butterfly valve. This plate on being tilted back so
that its top edge rests on the back part of the upright flue piece serves as a damper
to close off the connection to the flee from under the fire at the rear and on lifting
the fire cover adapts the range to the open fire form by opening the upright flue
or providing an open course for the flame and fire gases to pass through the usual
doorway in the flue piece to the chimney, whilst on tilting the plate so that its
upper edge rests on the front part of the upright flue the course from the top of
the fire is closed and that from the under side or from under the usual hot water
boiler is opened the range being thus converted to the close form when the fire
cover is replaced. The pivotted damper plate may be operated by a hand iron or
poker or a rod or link may be connected to it and carried through the flue piece to
a knob or handle outside.
Dated this Fourth day of April 1891.

COMPLETE SPECIFICATION.
Improvements in Cooking Ranges.
I, HUGH STEVEN, of the firm of McDowall, Steven & Co. Ironfounders, Milton
Iron Works, Glasgow, 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 to render cooking ranges more readily convertible
than hitherto from the open to the close fire form and as represented in the
accompanying drawings in transverse vertical section at Figure 1 and front elevation
at Figure 2 it consists in fitting within the ordinary vertical uptake or flue piece A
at the rear of the fire at B a damper plate C pivotted at c in the manner of a
butterfly valve. This plate C on being tilted back so that its top edge rests on
the back part A' of the upright flue piece as shewn in full lines serves as a damper
to close off the connection to the flue from under the fire at the rear and on lifting
or removing the fire cover adapts the range to the open fire form by opening the
upright flue or providing an open course for the flame and fire gases to pass through
the usual doorway D in the flue piece A to the chimney as indicated at Figure 1
whilst on tilting the plate so that its upper edge rests on the front part of the
upright flue as shown by the dotted lines the course from the top of the fire is
closed and that from the under side or from under the usual hot water boiler
is opened the range being thus converted to the close form when the fire cover is
replaced at B. The pivotted damper plate C may be operated by a hand iron or
poker or a rod or link may be connected to it and carried through the flue piece A
to a knob or handle outside.

page_text: Having now particularly described and ascertained the nature of my said inven-
tion and in what manner the same is to be performed, I declare that what I
claim is
In a cooking range a damper plate pivotted within the flue piece leading to the
chimney and arranged to operate substantially as described.
Dated this Fourth day of January 1892.
