PROVISIONAL SPECIFICATION.
Improvements in Ranges or Apparatus Employed for Cooking and
Heating Purposes.
I, WILLIAM HOUGHAM, of 39, Temple Row, Birmingham, Builder, do hereby
declare the nature of my said invention to be as follows:-
My invention for improvements in ranges or apparatus employed for cooking
and heating relates to the construction or combination of a cooking range or
stove with a boiler both of which may be removed when required being portable
and is chiefly applicable to the scullery for domestic purposes.
The aim of my invention is economy with utility, by dispensing witli the
waste of fuel which usually takes place, owing to there being two fires, one for
the cooking range, and another for the boiler.
"
I will describe my invention thus:-The cooking range is of that class which
has an oven on one side of the fireplace and a boiler on the other side, and a
pair of hinged flaps over the back of the fire so that the range may be worked
either with an
"
open or "closed" fire, above these flaps I provide a horizontal
damper, so that when the flaps are
open and the fire is an open one the
damper is also opened and the products of combustion go directly up the
chimney flue without circulating around either the boiler or the oven.

When it is desired to heat the oven, then the horizontal damper above men-
tioned is closed. The hinged flaps are also closed and the oven damper is
opened thus allowing the products of combustion to circulate round the oven
in a well understood manner.
I enclose the oven in a iron casing which serves as a support to it and as an
enclosure for the flue. Under the oven I provide a plate warmer and the top
is fitted to receive the culinary utensils.
I place the boiler on the other side of the fire from that on which the oven
is situated and in some cases employ a tap for emptying the contents.
The open boiler is carried loosely by two rings, one near the bottom and one
at the top which admits of an old or damaged boiler being easily replaced.
The upper ring serves to prevent the heat from getting to the actual top of the
boiler.
The boiler is bedded in a thick layer of sand arranged between the lower
ring and a bottom, this sand serves to retain the heat when it has become once
heated. The annular space surrounding the boiler serves as a flue through
which the hot products of combustion from the fire circulate before passing to
the chimney flue. which chimney flue is the same one which serves the range.
The outer wall of the flue around the open boiler is packed with asbestos or fire
clay or some similar bad conductor of heat, this preserves the outer iron casing
from injury & from heating and lessens the loss of heat hy radiation.
The annular flue has a partition across it close by the opening to the fire and
through which the products of combustion enter. by this means they are com-
pelled to circulate around the boiler.

Usually I put the boiler and the range in close juxtaposition to the fire the
range being on one side and the boiler on the other, but I may separate them
if local considerations make it desirable to do so. All the dampers I place in
a breeches piece at the base of the chimney flue.
I may vary the same as practice may determine according to its position or
requirement, without departing from the principle.

Improvements in Ranges or Apparatus Employed for Cooking and
Heating Purposes.
I, WILLIAM HOUGHAM, of 39, Temple Row, Birmingham, Builder, do hereby
declare the nature of this invention and in what manner the same is to be per-
formed, to be particularly described and ascertained in and by the following
statement:
My invention for improvements in ranges or apparatus employed for cooking
and heating relates to the construction of a metallic cooking range or stove,
with a metallic boiler in combination, both of which may be removed when
required being portable and is chiefly applicable to the scullery for domestic
purposes.
The aim of my invention is economy with utility by dispensing with the
waste of fuel which usually takes place owing to there being two fires one for
the cooking range, and another for the boiler.
And in order that this my said invention may be more clearly understood, I
will now proceed to describe the same more particularly and for that purpose
I shall refer to the sheet of drawings hereunto annexed the same letters of
reference indicating like or corresponding parts throughout all the figures.
Figure 1 is a view front elevation of a range or apparatus, in combination
with a boiler, employed for cooking and heating purposes, and constructed
according to my invention.
Figure 2 is a plan view of same.
Figure 3 is a view in elevation sectional of the boiler removed from the range,
and can be used more independantly.
Figure 4 is a view in elevation, end view of the range, the boiler being
removed.
a is the cooking range having the oven and the hinged flaps c c, d is the
horizontal damper, the oven damper, d² the boiler damper the breeches
piece. is the iron casing f is the plate warmer, g, g, are apertures to receive
the various culinary utensils.
On the side of I arrange the boiler h with its setting h¹ with the carrier
rings and having apertures and and with the seat at the boiler h is
supported, the rings i and j are supported by the cylindrical wall 7, which forms
the flue m and the space for the sand o, and the space p for the asbestos the
t is the inlet to the flue m, and fits
ring and the top R forms the space S.
into the aperture in w, while , is the outlet, is the door for access to m.
It will be perceived that my invention consists in having the oven 7, one one
i

page_text: side of the fire place, and the boiler on the other side, with the hinged
flaps c, c, at the back of the fire so that the range a may be worked with an
open or "closed" fire controlled by the damper d, when an
"
"
open" fire
this damper is opened, and the products of combustion escape up the chimney
flue without circulating around the oven b, or the boiler h.
But when desired to heat the oven b, the damper d and the flaps c, c, are
closed, and the damper d' is opened. thus the products of combustion circulate
around the oven b in the case e which supports the same.
The boiler being placed on the other side of the fire to the oven b and being
carried loosely by the rings i and ; and free in the seat k admits of its ready
removal in case of damage, the upper ring i prevents the heat reaching the
top of the boiler h which is important, the boiler h being embedded in the
sand 0, in the space n, between the lower ring jand the bottom, the sand o when
once heated serves to retain the heat in the boiler h. The space formed by
the wall and the outer casing his packed with asbestos or other material
which is a bad conductor of heat this preserves the outer case from injury and
heating and lessens the loss of heat by radiation.
When desired to heat the boiler the dampers d and d¹ and the flaps c care
closed, but the damper is opened, the heat now passes from the fire through
the aperture and by the inlet to the flue m which has a divisional plate m¹
extending its whole depth, compels the heat to take the course indicated by the
arrows, surrounding the boiler h and escaping by the outlet into the chimney
flue.
Preferably I arrange the boiler h and the range in close juxtaposition to
the fire but I may separate them when local considerations make it desirable,
but when the boiler h is separated from the fire of the range a it will be neces-
sary to arrange the fire under the boiler in some practical manner.
Having now particularly described and ascertained the nature of my said
invention, and in what manner the same is to be performed I declare that what
I claim is:-
In improvements in ranges or apparatus employed for cooking and heating
purposes.
1. The combination, of a portable metallic cooking range or stove, with a
portable metallic boiler, substantially as herein before described and illustrated
by Figures 1 and 2.
2. The construction and combination of parts forming a portable metallic
boiler, substantially as herein before described and illustrated by Figure 3.
3. The general construction, combination and arrangement of parts, substan-
tially as and for the purposes herein before described in the foregoing specifica-
tion and illustrated on the accompanying sheet of drawings.
