Improvements in Convertible Open and Close Fire: Ranges..
I, CHARLES MILLS, of 49, Smith Street, Govanhill, in the City of Glasgow,
Warehouseman, do hereby declare the nature of this invention to be as follows:-
This invention, which relates to cooking ranges of the convertible open and close
fire type, has for its object to make provision whereby the movement of the fire
cover in opening or closing the fire will open or close the hood or canopy through
which the fire gases pass to the chimney from the open fire.
The fire cover is fitted to slide under the back part of the hob in the usual way
and the hood or canopy is made in a common form consisting of a front plate
hinged at top to the back plate or covering over the smoke outlet so as to close the
outlet, and having side wings which pass through the opening. At the back of the
range a rock shaft is fitted in bearings to extend the full length of the chimney
opening and has at each end a bent or curved lever arm passing inwards close to
each side cheek of the hood or canopy whereon projecting studs are formed against
which the lever arms bear. At about the midlength of the shaft is a downwardly
projecting arm which normally lies in the path of movement of the fire cover. On
pushing back the cover to open the fire its rear end comes into contact' with and
raises this lever arm and by turning the rock shaft causes the curved arms on its
ends to press on the studs on the side cheeks of the canopy whereby the latter is
thrown forward at its lower end and opens the chimney outlet for the passage of
the gases from the open fire. On drawing back the fire cover to close the fire the
rock shaft is freed and the hood or canopy drops by its own weight against the
chimney opening in the coving or back of the range.
Improvements in Convertible Open and Close Fire Ranges.
I, CHARLES MILLS, of 49, Smith Street, Govanhill, in the City of Glasgow,
Warehouseman, 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 convertible open and close
fire type, has for its object to make provision whereby the movement of the fire

covering the opening through which the fire gases pass to the chimney from the
open fire.
The invention is illustrated by the accompanying drawings, Figure 1 being a
front elevation partly in section and Figure 2 a vertical section at right angles to
Figure 1, of the improved convertible open and close fire range.
The fire cover A is fitted to slide under the back part of the hob. B in the usual
way and the hood or canopy is made in a common form consisting of a front
plate Chinged at top at D to the back plate or coving E over the smoke outlet F
so as to close the outlet, and having side wings C₁ which pass through the opening.
At the back of the range a rock shaft G is fitted in bearings G2 to extend the full
length of the chimney opening F and has at each end a bent or curved lever arm G¹
passing inwards close to each side cheek C¹ of the hood or canopy C whereon
projecting studs C² are formed against which the lever arms G¹ bear. At about
the midlength of the rock shaft G is a downwardly projecting arm G3 which
normally lies in the path of movement of the fire cover A. On pushing back the
cover A to open the fire its rear end comes into contact with and raises this lever
arm G and by turning the rock shaft G causes the curved arms G¹ on its ends to
press on the studs C2 of the side cheeks 01 of the canopy C whereby the latter is
thrown forward at its lower end and opens the chimney outlet F for the passage of
the gases from the open fire. On drawing back the fire cover A to close the fire
the rock shaft G is freed and the hood or canopy C drops by its own weight
against the chimney opening F'in the coving or back E of the range.
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 convertible open and close fire ranges, a hood or canopy for covering and
uncovering the opening through which the fire gases pass, adapted to be opened
and closed by the action upon the hood or canopy of a bent lever arm actuated by
the movement of the fire cover substantially as described.
