page_text: I, JOHN WATSON, of St. Albans, in the County of Herts, Florist, do hereby
declare the nature of my said Invention to be as follows:-
The object of my invention is to construct a novel and improved form of stove
for use in horticultural and other buildings.
⚫ I construct my improved stove of metal and fire clay, and heat the same by the
combustion of coal gas or other gas, oil, coal, coke; wood, or other fuel.
The stove consists of an external cylinder; in which an inner cylinder is
placed; which is lined with fireclay, firebrick, or other suitable non conducting
material. Inside this again a central tube is placed, which is open from end to
end and is fixed to the bottom.
The lower end of the external tube is perforated or otherwise formed to admit a
current of air. An annular. diaphragm is fixed to the external tube, slightly above
the level of the floor, the inner tube being attached to the diaphragm. Surrounding
the internal tube I place two rings of gas burners, one above the other, the heat
from which is conducted or absorbed by the inner tube and the fireclay respectively.
Instead of gas burners, oil burners, lamps, coals, or coke, or other fuel may be
placed between the inner tube and the fireclay lining as herein before mentioned
suitable fire bars reservoirs of oil or other appliances being provided to suit the
particular description of fuel used. I sometimes also apply fireclay to the internal
surface of the inner tube.
When coal or coke is used, the inner tube is sometimes dispensed with.
Near the upper end of the stove I fit a moveable annular cistern to receive
water, the evaporation of which restores to the air some of the humidity which it
may have lost in its passage through the stove.
To the external tube I fit an attachment, whereby it can be fixed to a wall.
This attachment is more or less rectangular and is let into the wall and cemented
round; a suitable hole being cut in the wall; to enable persons to attend to the
stove without entering the building or room in which it is fitted, the external and
internal tubes being perforated to afford access to the combustion chamber.
A chimney or flue is fitted, which passes through the two external cylinders and
fireclay to the combustion chamber; by which chimney the products of combustion
are carried away.

I, JOHN WATSON, of St Albans, in the County of Herts, Florist, do hereby
declare the nature of my said invention and in what manner the same is to be
performed, to be particularly described and ascertained in and by the following
statement:

The object of my invention is to construct a novel and improved form of stove
for use in horticultural and other buildings.
I construct my improved stove of metal and fire clay, and heat the same by the
combustion of coal-gas or other gas, oil, coal, coke, wood, or other fuel.
The stove consists of an external cylinder; in which an inner cylinder is placed,
which is lined with fireclay, firebrick, or other suitable non-conducting material.-
Inside this again one or more central tube or tubes is or are placed, which is or
are open from end to end and fixed to the bottom.
The lower end of the external tube is perforated or otherwise formed to admit a
current of air. An annular diaphragm is fixed to the external tube, slightly above
the level of the floor, the inner tube being attached to the diaphragm. Surrounding
the internal tube I place two rings of gas burners, one above the other, the heat
from which is conducted or absorbed by the inner tube and the fireclay respectively.
Instead of gas burners, oil burners, lamps, coals, or coke, or other fuel may be
placed between the inner tube and the fire clay lining, as herein before mentioned;
suitable fire bars or other appliances being provided to suit the particular
description of fuel used. I sometimes also apply fireclay to the external surface
of the inner tube.
Near the upper end of the stove I fit a moveable annular or other cistern to
receive water, the evaporation of which restores to the air some of the humidity
which it may have lost in its passage through the stove.
To the external tube I fit an attachment, whereby it can be fixed to a wall.
This attachment is more or less rectangular is let into the wall and cemented round
or otherwise fixed; a suitable hole being cut in the wall, to enable persons to
attend to the stove without entering the building or room in which it is fitted, the
external and internal tubes being perforated to afford access to the combustion
chamber.
.
One or more chimney or chimnies or flue or flues is or are fitted, passing through
the two external cylinders and fire clay to the combustion chamber; by which the
products of combustion are carried away.
:
And in order that my said invention may be particularly described and
ascertained, reference is hereby made to the accompanying drawings, in which
similar letters of reference indicate corresponding parts.
and
Fig. 1 is a front view of one form of my invention, Fig. 2 is a sectional elevation
of the same on the line 1-2. Fig. 3 is a sectional elevation on the line 3-4;
Fig. 4 is a section on the line 5-6.
These bolts also secure
a is the front plate, secured to the wall b by bolts c c.
the casing d d to the wall ee is the outer portion of the stove, forming the outer

page_text: cylinder or space for air to pass upwards and become heated in its passage. ƒ ƒ are
holes for the entrance of the external air. gg is the space formed by the inner
casing hh and fire brick lining ii. In this space the burners k k are placed (when
gas fuel is used). is the central space, open from top to bottom, for the passage
of a current of air, which also becomes heated by contact with the walls. m is the
door, perforated with holes m¹ to admit air to the interior. The door is used for
lighting the gas or other fire and attending to the stove without entering the
apartment or building to be warmed. nn is the cistern for containing water, to
supply humidity to the air.
As herein before mentioned, the form of the stove and the character of the fuel
may be very much, varied, in some cases the stove is made of a cylindrical form,
the various concentric portions being modified accordingly to suit such, or any
other form. One or more funnels or flues is or are fitted to carry off the products
of combustion, and prevent the same from entering the building.
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. The manufacture and use of stoves, for the purposes aforesaid, constructed,
arranged, and operating substantially as herein before described and illustrated on
the drawings.
-
2. In stoves for the purposes aforesaid, the use of one or more central tube or
tubes 1, for heating an ascending column or columns of air, substantially as herein
before described and illustrated on the drawings.
3. The general construction, combination, and arrangement of the several and
respective parts, together forming my improvements in stoves for horticultural
and other purposes, substantially as herein before described and illustrated on the
drawings.
