page_text: Improvements in Liquid Fuel Stoves.
We, LEWIS WALKER LEEDS of 38 Old Jewry in the City of London, Heating and
Ventilating Engineer, and the L. W. LEEDS PATENT FLOOR WARMING STOVE
COMPANY Limited of 2 Copthall Buildings in the City of London do hereby declare
the nature of this invention and in what manner the same is to be performed, to he
particularly described and ascertained in and by the following statement :-
In the specifications to Letters Patent Nos. 5841 and 11930 of 1886 and 668 of
1887 are described certain constructions of gas and liquid fuel stoves.
The present
invention relates to further improvements therein, more particularly as regards the
construction of stoves in which liquid fuel is employed.
Where it is necessary to surround the flame so as to create a draught we propose
to so arrange the parts that the front will be formed of glass or mica, and part or
all of the sides of the draught flue will be formed of glass, mica, or metal, and the
'back of asbestos or other refractory material which need not he vertical but may
curve over the flame to a greater or lesser extent.
In order that the means by which the invention is carried into effect may be clearly
understood, reference is made to the accompanying drawings which form part of
this specification, and in which :—
Fig. 1 represents a sectional elevation of a stove on the line 1-2 of Fig. 2,
which in turn is an elevation on the line 3-4 of Fig. 1.
Fig. 3 represents an elevation on the line 5-6 of Fig. 4, which latter is an
elevation on line 7-8 of Fig. 3, while Fig. 5 is a plan view on the line 9-10 of
Fig. 5.
The stove body A is of metal, tiles, or other suitable material and carries an oil
or liquid fuel chamber B, from which rise suitable burners b, the flame from which
is caused to pass beneath an asbestos or other refractory arch C, which may be
composed of a fire brick clay or asbestos body carrying an asbestos floss facing.
The products of combustion pass up said arch into a hot air chamber D, from whence
there may be an exit flue d, although this is not necessary in the construction shown
in Figures 1 and 2.
In order to promote combustion and to secure a steady and even flame, it is
preferable to surround or encase the burners, and this we do preferably by glass or
mica sheets E, suitably held in the frame work while the requisite air supply is
obtained through openings F. In addition to the refractory arch C, reflectors G may
also be advantageously employed for reflecting and radiating the heat and light.
The form of stove shown in Figs. 1 and 2 is of the single type adapted for standing
in a fire place or against the wall. In this construction the flame chamber is
enclosed in front by the glass or mica sheet E, at the back by the asbestos arch C,
and at either side by plates or sheets H, so that the products of combustion are
compelled to pass up into the superposed chamber D, and much of their contained
heat is abstracted before said products eventually escape by the pipe d, or by the

page_text: openings I, neither of which communicate directly with the flame chamber but both
or either being open to chamber D. The form of stove illustrated in Figs. 3. 4 and 5
may be called a double or compound stove as it is intended to heat and light on
both sides, and for this purpose carries a double arch C. The main body of air to
support combustion is here intended to pass in through pipe F to chamber f, an
additional supply of more or less heated air passing in to chamber through
openings f¹, f, as indicated by the arrows. To promote combustion and prevent
smoke it is sometimes advisable to have an air chamber or supply F¹ to the
refractory mass C, with small or minor openings f to the asbestos floss. In this
construction as in that shown in Figs. 1 and 2, much of the heat carried up with the
products of combustion is abstracted before said products escape by pipe d which
opens to the bottom of the heat chamber D.
The reflector and radiator G, experience leads us to think, is best formed of
enamelled iron with a white or lightish colored face, and said reflector may be attached
to the top of the refractory arcb, but we prefer to attach it by projecting lugs g to the
casing A.
We do not of course confine ourselves to the use of enamelled iron as a material
for reflectors, nor do we confine ourselves to flat wick burners, for it will be evident
that the arch may he made as a curved cone standing on its apex and a circular wick
or burner be employed, in which case the stove is eminently adapted for standing
in the centre of a room or hall which it is desired to heat uniformly in all directions.
Having now particularly described and ascertained the nature of the said
invention, and in what manner the same is to be performed, we declare that what
we claim is:-
1st. In liquid fuel stoves the combination with the burner and supply chamber, of
a refractory arch above, and in the flame line, a casing surrounding said flame line,
suitable reflectors, and a superposed heat chamber, all substantially as set forth.
2nd. In liquid fuel stoves the combination with the burner and refractory arch, of
a superposed reflector arranged to radiate and reflect downward the heat, or heat and
light, substantially as set forth.
