Improvements in Cooking Ranges.
I, ARTHUR HABERSION, of Ferham Villa, Rotherham, 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:-
-
This invention has for its object to construct a cooking range so that, more
satisfactorily than hitherto :-
(a) the oven may be prevented from becoming overheated at that part which
is usually subjected to the direct action to the fire.
(b) a current of highly heated fresh air may be continuously passed through
the oven and the general temperature within the oven thereby rendered uniform,
and,
(c) the heat from the upper part of the fire (as distinguished from the lower
part as is usually the case) may be utilized for heating a boiler.
I will describe my invention by reference to the accompanying drawings in
which;
Figure 1 is a vertical section shewing, as an example, my present improve-
ments applied to a cooking range having an under-fed fire arranged according
to my British Patent No. 10182 of 1897.
Figure 2 is a perspective view of the oven and
Figure 3 is a perspective view of the boiler.
Like letters of reference indicate like parts throughout the different figures
of the drawings.
In carrying my invention into practice I provide outside those portions of the
oven A. (for example as shewn in the drawings, the top and one side) which are
usually overheated by the direct impingement thereon of the flames and heated
gases from the fire, a saddle or casing B, which, except for the openings a and b
hereinafter described completely encloses between itself and the wall of the
oven, a space wherein the air which is subsequently admitted to the oven, he-
comes very highly heated, this arrangement at the same time serving to protect
the oven against becoming overheated.
"
An opening 6 Figure 2 just above the oven and communicating with a similarly
situated opening in the range front, admits air into the casing B, and another
opening through the wall of the oven, and preferably near the bottom thereof,
allows the highly heated air to pass from the casing B into the oven A. In
order that the air may be kept a sufficiently long time in contact with the highly
heated casing B to raise it to the desired temperature, I provide the casing with
baffle plates 6' which cause the air to take a tortuous course in its passage through
the said casing as indicated by the arrows in Figure 2.
At the side of the oven preferably opposite to that provided with the open-
ing a I provide an opening a which allows the heated air, together with any
gases which may arise from the cooking operations carried on in the oven to
escape into the flue.

page_text: The before described openings a a¹ and 6 may, if desired, be provided with
any suitable valves or dampers.
I prefer to protect the vertical side of the casing B from the effects of the
fire, by covering it with an iron, fire-clay or other cheek.
In a kitchen range as hitherto constructed the boiler is heated principally
from the lower part of the fire, the heat from the upper part of the said fire
either being used for heating the oven, or, when the oven is not in use, allowed
to pass directly to the chimney and thereby wasted. To provide against this
waste of heat I form the boiler C with a flue c which passes through it from
front to back in a downwardly-inclined direction as shewn in Figures 1 and 3,
by which arrangement it is only necessary for the dampers (not shewn in the
drawings) to be properly adjusted to ensure that the heated gases from the upper
part of the fire shall pass through the flue c and thereby heat the water in the
boiler C instead of passing wastefully into the chimney as in ranges of ordinary
construction.
Although in the drawings I have represented my present invention as applied
to a range in which the fuel is supplied at the underside of the fire, in which
connection the before described boiler is particularly applicable, I do not confine
it to that application as it may be otherwise applied with very satisfactory
results.
Having now particularly described and ascertained the nature of this in-
vention, and in what manner the same is to be performed, I declare that what I
claim is:-
1. In a cooking range the combination with an oven, of a saddle or casing
such as having inlat and outlet openings, and baffle plates such as 1 sub-
stantially as and for the purpose hereinbefore described with reference to the
accompanying drawings.
2. The combination with a cooking range, of a boiler having an inclined flue
such as c with its inlet end near the top of the front and its outlet end near
the bottom of the back of the said boiler, substantially as and for the purpose
herein before described with reference to the accompanying drawings.
