Ironmonger, do hereby declare the nature of this invention to be as follows
My invention relates to kitchen or cooking ranges and has for its object to arrange
the fire-place and flues of the same in such a manner that the heat of the fire is
utilized more effectively than in ranges as hitherto constructed, so that a range of a
given size may be heated with a smaller fire than heretofore.
In my improved range the fire front or bars is or are hollow and the air for
supporting combustion is caused to pass through the same so that the air is heated
before it enters the fire which makes the range practically consume its own smoke.
The front of the range is entirely closed by doors and an ash-box, which doors can
be opened if a cheerful fire is required.

The flues are so arranged that the fire passes over the top of each

side to a fire brick and thence up the back of the oven (the flue being preferably of
the same width as the oven) into the chimney flue, the flues under the oven being

is heated by the fire direct.
The dampers are level with the hot plate and are so arranged that no soot can lodge
and cause à failure of the action of the range. The dampers when closed keep the
heat in the range and do not let the coverings get hot when not wanted; they also
keeps air from entering the flues of the range except by passing through the fire.
The ventilating pipe for the roaster oven is carried round the oven and the air
becomes heated before entering the oven. A top ventilator is provided for taking
away all smell from the oven and the cooking can be effected with the same open.
Instead of using two ovens I can fix an oven and a boiler or two boilers.
A great advantage of the improved range is that it requires very little fixing and
very few bricks.

Improvements in Kitchen or Cooking Ranges.
I, THOMAS ROGERS, of 27 The Triangle, Bournemouth, in the County of Hants,
Ironmonger, 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:-
My invention relates to kitchen or cooking ranges and has for its object to arrange
the fire place and flues of the same in such a manner that the heat of the fire is
utilized more effectively than in ranges as hitherto constructed, so that a range of a
given size may be heated with a smaller fire than heretofore.
In my improved range the fire front or bars is or are hollow and the air for
supporting combustion is caused to pass through the same so that such air is heated
before it enters the fire thereby causing the fire to practically consume its own
smoke.
The front of the range is entirely closed by doors and an ash-box, which doors can
be opened if a cheerful fire is required.
The dampers are level with the hot plate and are so arranged that no soot can lodge
and cause a failure of the action of the range.
The ventilating pipe for the roaster oven is carried in the flue round the oven, so that
the air becomes heated before entering the oven. A top ventilator is provided for
taking away all smell from the oven and the cooking can be effected with the same
open owing to the employment of special chambers.
To enable my invention to be fully understood I will describe how the same may
be carried into practice by reference to the accompanying drawings in which
Figure 1 is an elevation of a range provided with my improvements.
Figure 2 is a scection of the same on the line a, a; and,
Figure 3 is a vertical section on the line Figure 2.
Figure 4 is a central vertical transverse section through the fire box.
Figure 5 is a section on the line, Figure 1 and
Figure 6 is a view of a detail.
d is a high pressure
a, a are two ovens, and is the fire box having the grate c.
boiler, the walls of which form the sides and back of the fire box.
e, et are the doors for closing the fire box and fis the ash box. g is the hot plate
which is provided with removable rings of ordinary construction.
h, hare plates or partitions which are placed below the ash box and which serve to
direct the course of the air entering through the sliding door i and passing to the fire, the
direction of the air current being indicated by the arrow 1, 1, 1. These partitions h, are
arranged as shown in Figure 3 between side plates 7, which plates are heated by
the hot air passing through the flues hereinafter described, so that the air current
indicated by the arrows 1, 1, 1 will be more or less heated before it passes through
the fire.

page_text: jj are the flues which surround the oven, the hot air from the fire passing through
these in the direction indicated by the arrows 2, 2, 2 and j,jare auxiliary flues
arranged between the ovens and the boiler, through which the hot air passes in the
direction of the arrows 3, 3. In the portion of the flue j beneath each oven is a
diagonal partition which causes the hot air to pass over the whole of the bottom
surface of the said oven.
When it is desired to cause the fire to burn slowly the sliding door can be closed
in which case the air passes through an opening in the top of the ash box and
openings in the framing (Figure 1) in the side of the same in the direction
indicated by the arrows 4, 4, 4.
m is a flue which passes directly beneath the boiler and through which heat passes
in the direction of the arrow Figure 4 to the chimney.
n, n are dampers (one of which is shown detached in Figure 6) which serve to
control the passage of hot air through the flues j, j. These dampers are pivoted
below the level of the hot plate, as shown in Figure 2 and are slightly cut away at
the rear part, as indicated at o, to prevent soot from lodging thereon. The said
dampers are operated by rods p, p from the front of the oven.
4:9 are bent pipes or chambers which are arranged in the flues j, j beneath the
ovens and which at one end communicate with the atmosphere through the
openings, r, Figure 1, and at the other end with the oven as at 7, 1, Figure 3, so
that the air which enters the ovens in the direction indicated by the arrows 5, 5 is
heated.
s, s are slides which are arranged on the top of the oven and serve to uncover
suitable openings for permitting the escape of steam and hot air. Chambers or
cover t, are placed over the said openings, as shown in Figure 3 so that the escaping
air passes in the direction of the arrows 6, 6.
During the time that the ovens are being used it will be understood that the
doors e, e¹ are closed, in which case the air for supporting combustion passes through
the door and the openings l, in the direction indicated by the arrows 1, 1 and 4, 4
respectively, if both oven dampers are open and the Hue damper closed, the heated
air passes in the direction indicated by the arrows 2, 2 into the chimney. If both
oven dampers are closed the heat passes through the flue m, in the direction indicated
by the arrow 5.
In some cases the boiler can be dispensed with, in which case suitable firebricks are
substituted therefor. The fire will then act directly upon the upper parts of the oven
walls. Also if desired a boiler or boilers may be substituted for either or both of the
ovens.
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 :-
1. A kitchen or cooking range in which the air for supporting combustion is heated
prior to entering the fire by causing it to pass through a circuitous channel acted upon
by the fire whereby such air is heated, substantially, as and for the purpose, described.
2. The manufacture and use of the improved range hereinbefore described and
illustrated in the accompanying drawings.
