We JOHN FREDERICK WRIGHT and GEORGE ERNEST WRIGHT both of the Firm of
John Wright & Co. of Essex Works, Thimble Mill Lane, Aston, in the County of
Warwick Gas Engineers do hereby declare the nature of our said 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 improvements in gas cooking apparatus which allows
any articles requiring reflecting heat to be regulated as to distance from the burner
while the crown plate remains quite flat when it is desired to not use the distance
regulating device.
In order that our invention may be properly understood we have appended hereunto
a sheet of drawings upon which we have shown five figures illustrating the invention
as applied to one of our Gas Cookers which will serve to make its application to other
forms of gas cookers quite simple.
Figure 1 a perspective view of the cooker showing the apparatus when brought
into usé as applied thereto when in use.
Figure 2 is a broken off plan of the crown or oven plate with our new arrangement
closed down as it would be when not in use.
Figure 3 is a broken off plan of the oven plate casting as prepared ready to receive
the device.
Figure 4 is a cross section on line. A. B. Figure 2 with the device closed.
Figure 5 is a cross section on line C. D. Figure 3 showing the device open as
in use.
Our invention is shown as applied to our ordinary gas cooker, E is the body or
ordinary oven and H is the cornice with the bars upon which any vessel is placed
which requires boiling by the gas burners which are fixed immediately underneath the
bars of the cornice. K is the oven crown plate which is set a considerable distance
below the cornice H and it requires to be flat so as to hold a variety of articles at
various times. Now we fix our elevating apparatus to the crown plate K which is
accomplished by casting or forming the plate K whether cast or wrought iron with
recesses k¹ and k into which the doors or elevating flaps M and N fit when they are

page_text: closed down as shown by Figures 2 and 4. The flaps are hinged in prepared recesses
in K by projections m¹ and m³ and n¹ and n³ through which pins m³ and n³ pass
underneath the plate. The doors or flaps are opened by means of the projections m
and n* and each flap is provided with any convenient number of projecting slide
pieces m, m m and no no n' upon which the cooking dish or tin S slides. By thus
elevating the tin it is brought nearer to the burners and the cooking or heating
proceeds more rapidly. While this advantage is obtained the flaps may be instantly
turned down so as to leave the crown plate quite flat almost as though they did not
exist. It will of course be obvious that they may be placed at various parts of the
cookers with advantage and the shape will be designed according to the circumstances
of each particular case.
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 :-
The improvements in gas cooking apparatus of the elevating doors M and N mounted
upon the crown or other convenient part substantially as and for the purpose herein
set forth.
