Improvements in Gas and Oil Stoves.
I WILLIAM BRUCE DICK of Lytton House, Lytton Grove, Putney, London,
Merchant do hereby declare the nature of this Invention to be as follows:-
This Invention relates to that class of gas and oil stoves through which currents of
air are passed to be heated and in which the vapours or products of combustion after
circulating through the stove are condensed instead of being allowed to escape into
the atmosphere of the apartment and the Invention has for its object the provision
of improved arrangements of apparatus in such stoves whereby the combustion is
more effectively utilized in heating the air currents passing through the stove.
As
constructed in accordance with the Invention the improved stove consists of top and
bottom hollow casings the top casing being divided into upper and lower compartments
by a horizontal midrib or removable plate. The lower casing and the under com-
partment of the top casing are connected together by two tubes within which other
tubes are situated these passing through the under casing so as to communicate with
the atmosphere at their lower ends whilst their higher ends communicate with the
upper compartment of the top casing. The gas or oil burner is or may be supported
on the lower casing and above it there depends from the upper casing a tube into
which the funnel of the burner enter the said funnel passing through a diaphragm or
plate between the circumference of which and the interior of the tube an annular
space is left for the upward passage of air. The central tube communicates with the
lower compartment of the upper casing and through the side tubes with the lower
casing in which the gaseous products of combustion are condensed and from whence
they pass out through a hole or tap. In their passage to the lower casing the products
of combustion heat the air contained in and circulating through the interior side tubes
the said heated air being discharged into the higher compartment of the upper casing
and thence into the atmosphere of the room. Through the interior of the central tube
another air tube passes to the higher compartment of the upper casing the said tube
being knoed or bent immediately above the funnel of the gas or oil burner and from
the knee carried out horizontally the air to be heated entering at its lower end.
Under a modification the interior side tubes may be dispensed with in which case
one side tube serves to conduct the products of combustion to the condensing casing
whilst the other acts as an air heating tube the air passing in at its lower and out at
its upper end.

Improvements in Gas and Oil Stoves.
1. WILLIAM BRUCE DICK of Lytton House, Lytton Grove, Putney, London,
Merchant, 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 relates to that class of gas and oil stoves through which currents
of air are passed to be heated and in which the vapours or products of combustion
in circulating through the stove are condensed and it has for its object the provision
of improved arrangements of apparatus in such stoves for better effecting condensation
and for more completely utilizing the beat.
The Invention is illustrated in front elevation at figure 1, in plan at figure 2, in
vertical section at figure 3 and in detailed section at figure 4 of the annexed drawings

page_text: and as shewn by these figures the improved stove consists of top and bottom hollow
casings A, B, the top casing A being divided into upper and lower compartments 1, 2,
by a horizontal midrib or removable plate C. The lower casing B and the under
compartment 2 of the top casing A are connected together by two tubes D, within
which other tubes E are situated. The tubes E may pass through the under casing
so as to communicate with the atmosphere at their lower ends, as seen at the left
hand side of figure 2 or they may be terminated within the lower casing as seen at
the right hand side of the said figure, their higher ends in either case communicating
with the upper compartiment 1 of the top casing A. The gas or oil burner F, is or
may be supported on the lower casing E, and above it there depends from the upper
casing a tube G, which is double cased having an annular space 3 for the passage of
air between the casings. The funnel E of the burner enters into the lower end of
the said tube G, which end is otherwise closed by a diaphragm or plate I as shewn.
The interior casing of the tube G communicates with the lower compartment 2 of the
upper casing A and through the side tubes D with the lower casing B in which the
gaseous products of combustion are condensed and from whence they pass out
through a hole or tap 4. With the arrangement shewn at the left hand of figure 2,
the gaseous products in their passage to the lower casing B heat the air contained in
and circulating upwards through the interior side tubes E the said heated air being
discharged into the higher compartment 1 of the upper casing A and thence into the
atmosphere of the room whilst with the arrangement shewn at the right hand side of
the said figure the aeriform products of combustion after passing down the tubes D
are conducted up through the tubes E and are discharged with the heated air into the
apartment. Through the interior of the central tube G another air tube J
passes to
the higher compartment 1 of the upper casing A the said tube being kneed or bent
immediately above the funnel H of the gas or oil burner and from the knee carried
out horizontally to the annular space between the casings of the tube G from whence
the air already partially heated enters the tube J and is further heated before its
discharge into the apartment.
Under a modification illustrated in vertical section at figure 5 the interior side
tubes E are dispensed with and one side tube D, communicates between the lower
compartment 2 of the upper casing A and the lower casing B so serving to conduct
the products of combustion to the lower or condensing casing whilst the other tube D,
communicates with the condensing casing B and conducts the heated aeriform
products after the aqueous matters have been condensed out of them into the upper
compartment 1 of the top casing and thence into the apartment, or the lower extremity
of the said tube D may be open to the atmosphere as indicated by the dotted
lines in which case it acts as an air heating tube discharging the heated air at its
upper end.
With the arrangement figure 5 the compartment 2 is divided by a rib or web 5 to
regulate the circulation through the tubes D.
Having now particularly described and ascertained the nature of the said
invention, and in what manner the same is to be performed, I declare that what
I claim is :-
1. In a stove of the class sot forth the combination with the casings A, B and
tubes D of the diaphragm C and tubes and of a double cased tube G and air
heating tube J, arranged substantially as set forth with reference to figures 1 and 2
of the annexed drawings.
2. In a stove of the class set forth in combination with the casing B and tubes D
the casing A divided into upper and lower compartments the lower compartment being
also subdivided into two compartments, substantially as set forth with reference to
figure 5 of the accompanying drawings.
