Improvements in Cooking Stoves.
I, HOWARD MATRAVERS ASHLEY, of Ferrybridge, in the County of York,
Engineer, do hereby declare the nature of this invention to be as follows:-
:-
In low cooking stoves as they are usually constructed with a baking oven at the
side or at each side of the fire, it is difficult to make the fire serve for roasting and
also for heating properly the oven or ovens. The object of my invention is to avoid
this difficulty, which I effect by dividing the fire into two parts, the one fire and its
ash pan low down with a side flue extending under the oven on the one side, or
under an oven on each side, the other fire and its ash pan high up with its side flue
or flues conducting the products of combustion over the oven or ovens. The lower
fire is covered by a fire-brick arch separating it from the ash pan of the upper one.
The flues are directed so as to distribute the hot products of combustion over the
bottom, top and back surface of the oven, and suitable dampers are provided so as to
regulate the amount of heat applied to different parts.
Dated this 12th day of June 1890.

COMPLETE SPECIFICATION.
Improvements in Cooking Stoves.
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 :---

In low cooking stoves as they are usually constructed with a baking oven at the
side, or at each side of the fire, it is difficult to make the fire serve for roasting, and
also for heating properly the oven or ovens. The object of my invention is to avoid
this difficulty, which I effect by dividing the fire into two parts, the one fire and its
ash pan low down with a side flue extending under the oven on the one side, or
under an oven on each side, the other fire and its ash pan high up with its side flue
or flues conducting the products of combustion over the oven or ovens. The lower
fire is covered by a fire-brick arch separating it from the ash pan of the upper one.
The flues are directed so as to distribute the hot products of combustion over the
bottom, top and back surface of the oven, and suitable dampers are provided so as
to regulate the amount of heat applied to different parts.
Fig. 1 of the accompanying drawings is a front elevation of a low stove according
to my invention with a single oven at one side of the fire place.
Fig. 2 is a plan, part of the hot plate at the top being broken away to shew the
upper fire below it.
Fig. 3 is a vertical section on the line Z Z of Fig. 2.
E is the upper fire, which may have a grate with space F for ashpit below it as
shewn, or may have a brick bottoin. The products of combustion from this fire
pass, as indicated by the arrows e over the top of the oven O, and under the hot
plate M, and are prevented from flowing direct to the flue by a baffle L.
El is the lower fire, which may have a brick bottom as shewn, or may have a
grate with ashpit space below it. The products of combustion from this fire pass,
as indicated by the arrows h under the oven 0 and up behind it. Between the two
Prine 17

page_text: fires E and H there is a brick arch G. According to this construction, no
descending flue is required, as in ordinary oven stoves, and, owing to the direct
course provided for the products of combustion, very little draught is required and
consequently the combustion is slow and fuel is proportionally economised: The
one fire E can be used alone for cooking by heating the hot plate M, or the other
fire H can be used alone for baking by heating the oven O, or both fires can be used
together.
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
The construction of a cooking stove with two fires, the one above the other, and
their flues, arranged and operating substantially as described.
