PROVISIONAL SPECIFICATION.
Means of Utilising the Jambs and Lintel of a Fireplace for Cooking
Purposes.
I, HOWARD MATRAVERS ASHLEY, of Ferrybridge, in the County of York, Engineer,
do hereby declare the nature of this invention to be as follows:-
It is often necessary to provide, in addition to the ordinary fires or stoves for
cooking, smaller gas stoves for cooking sauces, and other small dishes.
My invention relates to means of utilising the jambs and lintel, and in some cases
also the mantel shelf, of a fireplace for this purpose.
I make these of metal, hollow so that there is a cavity between their fronts
and the wall against which they are fixed, and in cases where this cavity is too narrow
from front to back, I make recesses in the wall to give the necessary depth at several
places for chambers, such for instance as two places in each jamb, and two places in
the lintel.
At each of these places I provide a door which may be conveniently hung by its
upper edge and made with two side cheeks. This door can when required be turned
up to a horizontal position and a gas burner, which is usually accommodated within
the chamber, can be turned down to receive over it and under the turned up door a
saucepan or other cooking utensil. The door and burner may be otherwise hung or
in some cases arranged to slide.
From the space behind the jambs and lintel there is a communication to the
chimney and thus there is a passage and draught by which the products of combustion
and the vapours are carried away without coming into the apartment. Instead of
making the whole of the jambs and lintel project sufficiently far to accommodate the
appliances described, in many cases it may suffice to make only the end parts of the
lintel, immediately over the jambs, of sufficient depth to form small oven chambers, in
which gas cooking can be effected.

Means of Utilising the Jambs and Lintel of a Fireplace for Cooking
Purposes.
I, HOWARD MATRAVERS ASHLEY, of Ferrybridge, in the County of York,
Engineer 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 :-
It is often necessary to provide, in addition to the ordinary fires or stoves for
cooking, smaller gas stoves for cooking sauces, and other small dishes.
My invention relates to means of utilising the jambs and lintel, and in some cases
also the mantel shelf, of a fireplace for this purpose.
I make these of metal, hollow so that there is a cavity between their fronts and the
wall against which they are fixed, and, in cases where this cavity is too narrow from
front to back, I make recesses in the wall to give the necessary depth at several places
for chambers, such for instance as two places in each jamb, and two places in the
lintel.
At each of these places I provide a door which may be conveniently hung by its
upper edge and made with two side cheeks. This door can when required be turned
up to a horizontal position and a gas burner, which is usually accommodated within

page_text: the chamber can be turned down to receive over it and under the turned up door a
saucepan or other cooking utensil. The door and burner may be otherwise hung or
in some cases arranged to slide.
From the space behind the jambs and lintel there is a communication to the
chimney or other flue and thus there is a passage and draught by which the
products of combustion and the vapours are carried away without coming into
the apartment. Instead of making the whole of the jambs and lintel project
sufficiently far to accommodate the appliances described, in many cases it may
suffice to make only the end parts of the lintel, immediately over the jambs, of
sufficient depth to form small oven chambers in which gas cooking can be effected.
The accompanying drawings represent my invention as applied to one of the
jambs of a cooking or other stove. Fig. 1 is a front view of the jamb. Fig. 2 is
a vertical section and Fig. 3 is a sectional plan on X X of Fig. 2. The jamb A
projecting from the wall has a space behind it from which space I make a passage
to a flue to draw off vapours or fumes. At a convenient height I fit to the jamb
a door B made preferably with side cheeks b and hinged at the top edge and
provided with a suitable catch to hold the door open when required.
hinge also
to the jamb a platform (carrying an atmospheric gas burner supplied with air
and gas by a pipe c. This platform and burner when not in use can be turned
up to a position within the jamb such as is indicated by the dotted lines C¹, and
concealed by closing the door B. To allow for the movement of the platform and
burner, the hinge may be trunnion jointed as shewn, and one of the joints may
be arranged as a stopcock which is opened only when the platform is turned out-
wards for use.
The connection to the burner might however be made by a flexible tube, which
may communicate with the burner through a cock having a lever so set that when
the platform is turned inwards the lever comes against a fixed stop and is moved
so as to close the cock.
Although I have shewn only one set of apparatus in a jamb there might be several
of them at various heights in either jamb or in both, and obviously they might also
be applied to the projecting lintel which carries the mantel piece.
Having now particularly described and ascertained the nature of this inven-
tion and in what manner the same is to be performed I declare that what I
claim is :-
Providing the hollow jamb or lintel of a fire place or stove with an opening furnished
with a door and with a cooking platform and burner, constructed and arranged
substantially as and for the purpose herein set forth.
