Improvements in Fumigators.
I, THOMAS SMITH of 41 Dover Street Folkestone Kent Gardener do hereby declare
the nature of this invention to be as follows:-
The object of my invention is to fumigate plants & flowers for killing insects or
other parasites. For the purpose of my invention I form an air-tight frame of any
size, shape, & material to which I affix a stove in any required position preferably
outside burning any suitable fuel. I place in the most convenient position the
fumigating powder or other suitable substance, the smoke from which passing through
a funnel & acting on the plants or other objects placed in the frame effectually
destroys all parasites without injury to the plants.

COMPLETE SPECIFICATION.
Improvements in Fumigators.
THOMAS SMITH 41 Dover Street, Folkestone, County of Kent, Gardener, 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:--
The object of this my Invention is the construction of an apparatus or stove in
which herbs, chemical powders, liquids, or other materials are burned in such a manner,
that the smoke or vapour produced by applying heat to such substances or liquids
after being caused to pass into an air-tight frame or structure in which plants or
other objects are placed effectually kills all parasites, without injury to the plants or
objects placed therein.
For the purpose of my Invention I form an apparatus or stove of a conical or other
convenient shape, having a grating or plate with several apertures or holes therein,
on which said plate or grating the fumigating material or liquid is to be placed,
immediately beneath the said grating I form a chamber or space in which I place a
stove containing oil, spirit, coal, coke or other liquid or material with which to
generate heat, and slowly consume the fumigating material or liquid placed on the
aforesaid grating, and causes a vapour or smoke to emanate, which said smoke or
vapour passes upwards through a conical thimble or cap having several perforations
formed therein, the smoke or vapour after passing through the said perforated cap or
thimble is conducted by a pipe or pipes into the before mentioned air tight structure,
on the outside of which it is preferably placed. An adjustable aperture is formed in
the outside or casing of the lamp or fuel chamber, and also in the outside wall or
casing of the chamber or space in which the fumigating material or liquid is
consumed, for the purpose of admitting more or less air as required during the
process of fumigating. The fumigating chamber and stove may be constructed any
convenient size, according to the number of plants it is required to treat at one time,
and the said stove may be successfully used for producing vapour or smoke required
to be inhaled by persons in hospitals, sick-rooms &c.
In order that my Invention may be more readily understood and explained in
detail, I have hereunto annexed a sheet of Drawings on which letters of reference are
marked on corresponding parts on all the Figs. alike.

page_text: DESCRIPTION OF DRAWINGS.
Fig. 1 is a view of the air tight structure, with one of my improved stoves attached
to the front thereof, it may however be placed at the side found most convenient.
Fig. 2 is a front elevation of my improved stove, used for fumigating purposes.
Fig. 3 is a vertical section of same, with the top conducting pipe removed, shewing
more clearly the chamber in which the heat producing product is placed, and the
grating on which the fumigating material or liquid is burned, and the perforated
conical cap.
Fig. 4 is a complete plan of the conical perforated thimble or cap, through which
the smoke issues on its way to the fumigating chamber.
Fig. 5 is a sectional plan, (taken through the line A. B. of Fig. 3.) of the perforated
grating or plate on which the fumigating material or liquid is placed and consumed,
so as to forin smoke or vapour.
Fig. 6 is an enlarged view of the perforated cap.
In these Figs. a is the air tight structure constructed with or without shelves
inside, the whole of which is made of wood, metal or other suitable materials, having
a window a² of suitable size for the purpose of inspecting the plants at various stages
of fumigation, bis the stove attached to the outside of the said Fumigating Chamber
by any suitable means, c is the chamber in which the heat producing product is placed,
immediately above which is the perforated grating or plate d on which the fumigating
material or liquid is burned, e is the perforated conical cap or thimble; through the
holes of which the smoke or vapour passes on its way to the aforesaid fumigating
chamber a. fand f2 are the adjustable air admitting apertures in the lamp and
fumigator consuming chambers respectively.
Having now particularly described and ascertained the nature of my said Inven-
tion and in what manner the same is to be performed, I declare, that what I
claim is ;-
The principle of constructing an apparatus or stove, in the manner herein described,
in which various materials or liquids are to be burned, the smoke or vapour arising
from which fumigates or rids plants of the parasites which infest them, or for the
purpose of inhalation by persons in hospitals or sick rooms, as herein substantially
described, set forth, and fully illustrated in the Drawings annexed.
