Haden Richardson at the Office of the Commissioners of Patents,

We, CHARLES SELLERS, of the City & County of York, and
WILLIAM HADEN RICHARDSON, of Glasgow, in the County of Lanark,
North Britain, do hereby declare the nature of the said Invention
of "IMPROVEMENTS IN STOVES," to be as follows, that is to say :-
This Invention which relates to improvements in stoves, consists in
constructing them with a cylindrical or other shaped chamber at the
interior of an outer casing, into which chamber atmospheric air is con-
ducted by a pipe situate at its lower part, and which communicates with
the outside of the building or with the interior of the apartment within
which the stove is placed. The lower end of the aforesaid chamber is
placed above a gas burner, and by preference a conic, or concave, or
convex surface is formed at the bottom of the chamber in order to
confine the heat proceeding from the burner and also to afford a greater
heating surface to the air, which when heated passes through a pipe in
the upper end of the cylinder or chamber into the apartment in which
the stove is placed. The bottom of the chamber may however be flat or

page_text: the chamber may have tubes passing through it. An open space may
be situated between the outer surface of the cylinder or chamber, and
the inner surface of the casing of the stove around which the products of
combustion may pass upwards or downwards, and after having parted
with their heat to the air are discharged into a chamber and thence
through a flue or chimney at the upper or lower part of the stove.
In lieu of conducting the air through the chamber and causing the
products of combustion to circulate around it, the said products may be
passed through a chamber and the air to be heated conducted into a space
between a chamber and the outer casing of the stove, and in order to
afford a greater heating surface to the air the sides of the chamber may
be fluted or corrugated or the air may be conducted through tubes
situate in the space, or the said space may be divided by shelves, gills, or
diaphragms into a zig-zag or tortuous passage through which the air
may be passed, being heated by gas or a coal fire.
Under another arrangement of the stove the air to be heated in lieu of
being conducted through a chamber or through passages or tubes situate
at the interior of the stove as herein-before described, is conducted
through a chamber placed on the top of the stove, which chamber may
be constructed with vertical or horizontal diaphragms, shelves, or gills at
the interior, so as to form a tortuous or zig-zag passage for the air, or it
may be made without the said diaphragms, shelves, or gills, or one or
more tubes may be placed at the interior of the chamber through which
the products of combustion from the stove may be conducted so as to
heat the air circulating around the said tube or tubes.
Under another arrangement of stove it consists of a series of air tubes
with or without gills at the interior, placed parallel to each other in
vertical planes, and connected together so that the air to be heated
passes from one tube to the other, the tubes communicating with each
other alternately at their upper and lower ends or in place of being so
connected each tube may be independent, the air in this case being
admitted at the bottom and discharged at the top of each tube, and
heated by gas or a coal fire.
Under another arrangement of stove it consists of a chamber having
gills or shelves at the interior of the hollow space for the purpose of
retarding the current of air and enabling it to take up the heat. The
outside casing of the stoves herein-before mentioned may be made of

page_text: metal, terra cotta, or fire-brick, or of terra cotta or fire-brick and metal
combined, and the same may be japanned or ornamented with tiles or
glass, or both, and in order to preserve the ornamentation from the
destructive action of the heat an air space or jacket may be formed
round the interior of the outside casing in addition to the air chambers,
passages, or tubes herein-before set forth, and through which the outer
air may freely circulate.
As in existing arrangements a water pan or vessel may be provided in
conjunction with the improved stoves constituting this Invention, in
order to render the air more humid, and the said stoves may also be
provided with a boiler for heating water if desired.
