PROVISIONAL SPECIFICATION.
An Improved Fumigator for Destroying Insects in Plants, and for
similar purposes.
I, EVAN GRIFFITHS HUGHES, of Victoria Street, Manchester, Chemist, do
hereby declare the nature of this invention to be as follows:-
1
The improvements relate to fumigators and have for object the production of a
cheap and simple fumigator which is also reliable in practice.
To accomplish this and to effect my improvements, I employ any suitable paper
which has been charged with or immersed in any insect poison, such for instance
as nicotine or other substance, which when burnt or vaporised has the power of
destroying insects or the like.
This paper I cut to suitable size and roll it into tubes of any required thickness
or number of folds. These tubes I bind or hold together, in any suitable number
or form, as a bundle. They are either so held together by being bound together
by wire, or twine saturated with alum, or by any incombustible means; or by being
placed in a card-board case, rendered' incombustible or partially so; or a case may be
composed of wire in skeleton form; or of tin or zinc or other sheet or other metal
which may be perforated or not. Such case or binding may be also formed as a
stand or holder, which may be arranged either to stand on its base, or to be hung
up or suspended from above..
In practice, the tubes of paper are, by preference, lighted at the bottom and burnt
upwards; but it would be possible to burn such a bundle of tubes laid on its side or
at an angle, and other variations in detail may be made without departing from the
peculiar character of the invention.

COMPLETE SPECIFICATION.
An Improved Fumigator for Destroying Insects in Plants, and for
similar purposes.
I, EVAN GRIFFITHS HUGHES, of Victoria Street, Manchester, Chemist, 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 improvements relate to fumigators, and have for object the production of a
cheap and simple fumigator which is also reliable in practice.
To accomplish this, and to effect my improvements, I employ any suitable paper,
or other fibrous material, which has been charged with or immersed in any insect
poison, or other drug, such, for instance, as nicotine, fir tree oil, or other substance,
which, when burnt or vaporised has the power of destroying insects or the like.
This paper or other fibrous material I cut to suitable size and roll' it into tubes of
any required thickness or number of folds, which tubes are, by preference, in the
form of a circular ring in cross section, though they may be of any convenient form,
and prepared by any suitable means, such as, for example, by folding the paper, or
other fibrous material- over a shaped centre core, which is afterwards withdrawn.
Each of these tubes or rolls may be caused to retain their rolled or folded condition
by means of gum or glue, or by other means, if found desirable, and the charging
with or immersion in the insect poison or other drug may take place either before
or after the rolling or folding is accomplished.

page_text: The tubes thus formed and prepared, I next bind or hold together, in any suitable
number and shape, as a bundle or group. They are either so held together by
being bound together by wire, or twine saturated with alum, or by any incombustible
means; or by being placed in a card board case, rendered incombustible or partially
80, or a case may be composed of wire in skeleton form, or of tin or zinc or other
sheet or other metal which may be perforated or not. Such case or binding may
be also formed as a stand or. holder, which may be arranged either to stand on its
base, or to be hung up or suspended from above:
In practice, the tubes of paper or other fibrous material: are, by preference,
lighted at the bottom and burnt upwards, but it would be possible to burn such a
bundle of tubes laid on its side or at an angle.
I am aware that fumigators have been prepared of corrugated paper or card
attached to plain sheets of paper, and coiled into a spiral, and other forms of
fumigators have been employed which permit the burning vapours to pass through
passages formed by corrugations or otherwise, but such fumigators are distinct
from this my present invention.
other
Variations in detail may be made, such as the thickness of the paper or
fibrous material forming the tubes, the manner of binding such tubes togethor, the
size thereof, and the number in each bundle or group; and each tube or roll may
be formed of more than one sheet of paper or other fibrous material, without
departing from the peculiar character of the invention.
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:-
:
A fumigator for destroying insects in plants, and for similar purposes, formed by
binding together, in a bundle or group, a number of combustible tubes, charged
with insect poison or other drugs, which tubes are separately formed of paper, or
other fibrous material, in manner substantially as herein described.
