PROVISIONAL SPECIFICATION.
A New or Improved Fumigator for Destroying Insects in Plants and
for other analogous purposes.
I ROBERT CAMPBELL of Lostock near Northwich, in the County of Chester,
Gardener, do hereby declare the nature of my said invention to be as follows:-
The object of this invention is to produce a simple and reliable fumigator for
effectually destroying insects in plants and for other analogous purposes.
Now this invention consists in the employment of a (by preference) rectangular
shaped sheet of thick paper or thin pasteboard coated with or immersed in a well
known insect poison solution, consisting of nicotine, lime and essential or volatile oils
and upon which is mounted and affixed (by means of gum, flour-paste or other suitable
adhesive substance) a similarly shaped sheet of thick paper which is corrugated, crimped
or fluted along its entire length. The two papers are then rolled together in a spiral
or voluto form and to retain them in the coiled position they are surrounded by an
envelope or belt of paper, and so constitute my improved fumigator.
The fumigator is now ready for use and by providing it at one end with a wire
hook or chain the same can be suspended vertically from say the branch of the plant
to be treated or from any part of a horticultural building. The lower end is then
ignited but the non-inflammable nature of the poisonous clement used, prevents a
flame and only allows the paper to smolder and give off fumes. These fumes ascending
pass up the channels or passages within the fumigator formed by the corrugated paper
and escape at the top thereof on to the plant or into the atmosphere.
To prevent any chance of the outer wrapper or belt taking fire I coat the same
with asbestos paint or other non-inflammable material.

COMPLETE SPECIFICATION.
A New or Improved Fumigator for Destroying Insects in Plants and
for other analogous purposes.
I, ROBERT CAMPBELL of Lostock near Northwich in the County of Chester,
Gardener 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 this invention is to produce a simple and reliable fumigator for
effectually destroying insects in plants and for other analogous purposes.
On the accompanying drawing I illustrate in Fig. 1 a side view (partly in section),
and in Fig. 2 a plan view of my improved fumigator.
Now this invention consists in the employment of a rectangular shaped sheet of
thick paper or thin paste board coated with or immersed in any well known insect
poison solution for instance that consisting of nicotine, lime and essential or volatile
oils and upon one face of which is affixed (by means of gum, flour-paste or other
suitable adhesive substance) a similarly shaped sheet of thick paper but which is
corrugated, crimped or fluted transversely along its entire length. These two papers
indicated by letters a and b in the accompanying drawing are then rolled together
in a spiral or volute form as illustrated more clearly in Fig. 2 and to retain them in
the coiled position they are surrounded by an envelope or belt of paper c and so
constitute my improved fumigator.
The fumigator is now ready for use and by providing it at one end with a wire
DC1

page_text: hook or chain d the same can be suspended vertically from say the branch of the plant
to be treated or from any part of a horticultural building. The lower end is then
ignited but the non-inflammable nature of the poisonous element used prevents a flame
and only allows the paper to smoulder and give off its poisonous fumes. These fumes
ascending pass up the channels or passages within the fumigator formed by the
corrugated paper and escape at the top thereof on to the plant or into the
atmosphere.
To prevent any chance of the outer wrapper or belt c taking fire I coat
the same with asbestos paint or other non-inflammable material.
Having thus particularly described and ascertained the nature of this my said
invention and in what manner the same is to be performed, I declare that what
I claim is: :-
The new or improved fumigator substantially as and for the purpose hereinbefore
described and illustrated.
Dated this 3rd day of November 1890.
