I, ZEPHANIAH DEACON BERRY, of Pimlico, in the County of Middle-
sex, Civil Engineer, do hereby declare the nature of the said Invention
for "IMPROVEMENTS IN THE CONSTRUCTION OF STOVES FOR HEATING BUILDINGS AND
OTHER PURPOSES," to be as follows:-
:-
This Invention consists of improvements in the construction of stoves
for heating buildings and for other purposes, and by means of which
the desired results are obtained in an efficient manner. The fuel is
supplied to the stove by and is contained in a vertical cylindrical
chamber, the upper part of which is provided with a hopper and the
lower end thereof descending to the fire-box, the diameter of which is
larger than that part of the fuel chamber which is immediately above it.
The fuel is supplied at the upper part of the chamber by means of the
hopper and freely descends to the fire-box, an annular space being
provided between the outer diameter of the latter and the lower part
of the fuel chamber for the upward passage of the products of com-

page_text: bustion. The external air is heated by means of conducting plates of
metal which form a part of the body of the stove, and project therefrom
in a horizontal or vertical position, and which plates are perforated so
as to allow the passage of the air from the lower surface of the room or
place in which the stove is situated. The perforations are so arranged
as to be in the same vertical line in each alternate plate only. The
current of air produced by the heated stove is thus caused to pass
upwards from plate to plate in a serpentine or zig-zag direction,
whereby it is well heated by coming in contact with the heated
surfaces.
The stove internally is is provided with a number of plates connected
with the outer part of the stove, and which are perforated in such a
manner as to allow of the free passage of the products of combustion
to the chimney. The space between the upper part of the fire-box
and the lower part of the fuel chamber is sometimes filled with tubes
for heating water when it is desirable that warm water should be used
for heating purposes.
The fire-box is constructed with fire-bars, or with a solid or dead plate
at the bottom thereof of any suitable material, or may be formed of
hollow bars for the purpose of heating water. The stove may be made
in several pieces fitting one above another, so that the conducting plates
and a part of the stove form one piece for the purposes of conduction,
and care being taken by means of well-known contrivances that the

supplied to the fire through a register in the ash pan or through the
fire-door, according as the fire-box is constructed with a solid bottom or
with fire-bars. The upper part of the fuel chamber is made smoke-tight,
and is so constructed as to have a water receptacle which may if desired
form a water joint.
A modification of this Invention especially adapted for heating green-
houses, offices, and other places, is as follows:-The fire-box is so con-
structed that the products of combustion pass outward at the back
thereof, which may be closed in with the lower part of the fuel
chamber or may be arranged as in the stove herein-before described.
In either case the products of combustion do not ascend to the top
of the stove but pass through the back of the fire-box, and through
a series of horizontal pipes, and eventually to the chimney. The air
of the place desired to be warmed is heated by coming in contact with

page_text: the surfaces of the pipes, which may be fitted with conducting plates,
such as those before described, but modified so as to be suitable to this
adaptation. The air is supplied to the fire-box either through the ash
chamber or through the door of the fire-box, the bottom of which may
be either solid or formed of ordinary fire-bars or of water pipes.
