PROVISIONAL SPECIFICATION.
New or Improved Appliances to be employed for Fumigating Plants
and the like.
We ISAAC SHIMWELL MCDOUGALL and JAMES THOMAS MCDOUGALL both
of 10 Mark Lane in the City of London Manufacturing Chemists do hereby
declare the nature of this invention to be as follows:—
The object of this invention is to provide appliances which can readily be fixed
in place and will enable fumigation of plants or the like to be performed with
efficiency and rapidity.
According to this invention we employ arrangements whereby sheets or coverings
of textile or other suitable material are capable of being applied with facility so as
to enclose or partly enclose the plant or plants which is or are to be fumigated in
the open. The sheets or coverings may if necessary be covered or impregnated
with bituminous material paraffin wax or other matter which will make them more
capable of retaining the fiumigating vapours. In order to support these sheets or
coverings I provide in cases where there is a considerable extent of ground to be
covered any required number of supports which may be made in parts adjustable
and fixable so as to make them capable of being adjusted to and fixed at any height
so that the sheet or sheets are supported thereby over the plants to be fumigated.
These supports may for instance consist of a telescopic arrangement of metal tubes
with supporting feet and fixable at any height by means of a series of holes and a
pin or of a picce somewhat like a stool with a hole in its top into which is passed a
vertically adjustable rod or the like which carries a hook or a forked or rest piece
or eyes by which a bar or rod or a wire or other rope may be supported or through
which it may be passed say at each end by one of the aforesaid supports and the
sheet can be passed over this rod or bar or over the rope or ropes which may bc
stayed to the ground if necessary by carth pins. The tops of these supports may
have knobs or rounded terminations to prevent injury to the sheets passed over
them. Or in the case of plants climbing around poles I may provide a cap piece
of tin or other suitable material for being placed upon the pole or poles the lower
part being secured to the sheet so that it hangs down and encloses the plants. The
sheets especially when they are to be applied to large plants such as trees or bushes
may have loops or rings in them by means of which poles with for instance forked
or hooked ends inserted in the said loops or rings can be used to lift the said
sheets to cover the plant. These poles at their other ends may be furnished with
a disc or the like so that they may be used for supporting or easing the
sheets when required. In all cases the sheets serve to keep the fumes which
have been introduced into or generated under the sheets in proper contact with
the plants.

and the like.
We, ISAAC SHIMWELL M'Dougall and James THOMAS MCDOUGALL both
of 10 Mark Lane in the City of London Manufacturing Chemists do hereby
declare the nature of our 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 provide appliances which can readily be fixed
in place and will enable fumigation of plants or the like to be performed with
efficiency and rapidity.
According to this invention we employ arrangements whereby sheets or coverings
of textile or other suitable material are capable of being applied with facility so as
to enclose or partly enclose the plant or plants which is or are to be fumigated in
the open. The sheets or coverings may if necessary be covered or impregnated
with bituminous material paraffin wax or other matter which will make them more
capable of retaining the fumigating vapours. In order to support these sheets or
coverings there is provided, in cases where there is a considerable extent of ground
to be covered any required number of supports which may be made in parts
adjustable and fixable so as to make them capable of being adjusted to and fixed at
any suitable height so that the sheet or sheets are supported thereby over the plants
to be fumigated. These supports may for instance consist of a telescopic arrange-
ment of metal tubes such as is shewn at the left hand side of Figure 1 of the
accompanying drawings consisting of a rod or tube a sliding in a tube 6 provided
with supporting feet (which may be pointed to be readily pressed into the
ground) and fixable at various heights by means of a series of holes a² and 6 passing
through a and b at various heights through which is passed a pin c. Or the said
supports may consist of a piece somewhat like a stool consisting of a top part d
with legs e the part d having a hole in its top into which is passed a vertically
adjustable rod or the like. This is shewn at the right hand side of Figure 1.
The rods a and carry cach a hook or a forked or rest piece or eyes by which a
bar or rod or a wire or other rope may be supported say at each end by one of the
aforesaid supports and the sheet can be passed over this rod or bar or over the rope
or ropes which may be stayed to the ground if necessary by earth pins. In
Figure 1 this is shewn as consisting of the rope g passed through holes in the upper
ends of the rods a and and stayed to the ground. The rod fis adjusted to various
heights and secured in the adjusted position by a pin passed through one or other
of the holes and resting on the top part d. The tops of the said rods a and of
the supports may have knobs or rounded terminations as at af to prevent injury
to the sheets passed over them. Or in the case of plants climbing around poles I
may provide a cap piece (as shewn in Figure 2) of tin or other suitable material
for being placed upon the pole or poles the lower part being secured to the sheet
(part of which is shewn at j) so that it hangs down and encloses the plants. The
sheets especially when they are to be applied to large plants such as trees or
bushes, may have loops or rings in them by means of which poles with for instance
forked or hooked ends inserted in the said loops or rings can be used to lift the said
sheets to cover the plant. One of the sheets suited to be passed over the rope g is
shewn in Figure 3. It has rings along its sides and also down its middle. They
can be conveniently attached by means of canvass loops secured to the sheet as
shewn in detail in Figures 4 and 5 Figure 4 shewing a ring at the edge and
Figure 5 a ring at the middle. One of the hooked poles is shewn at Figure 6. It
has at its butt end a disc m or the like so that the said poles may be used for
supporting or easing the sheets when required. In all cases the sheets serve to

page_text: keep the fumes which have been introduced into or generated under the sheets in
proper contact with the plants. The rings in some cases serve to pass a cord
through to draw the sheet together or to join several sheets to properly enclose the
plant.
Having now particularly described and ascertained the nature of our said inven-
tion and in what manner the same is to be performed we declare that what we
claim is:
1st. A sheet for the purpose described made of a fabric impregnated or covered
with bituminous matter or paraffin wax or their equivalents substantially as
hereinbefore explained.
2nd. For the purposes described supports constructed substantially as herein-
before described and shewn under two modifications in Figure 1 of the accompanying
drawings.
3rd. For the purposes described a cap piece to which a sheet is attached
as herein before explained with reference to Figure 2 of the accompanying
drawings.
4th. For the purposes described a sheet provided with rings or their equivalents
as hereinbefore described and illustrated by Figure 3 of the accompanying
drawings.
