Improvements in Apparatus for Fumigating or for Delivering Liquid
in the Form of Spray or in a Stream or Streams.

Mandril Tube Works, 86, New John Street West, Birmingham, Warwickshire,
Manufacturers do hereby declare the nature of this invention to be as follows:-
=
"
This invention consists in the herein described improvements in apparatus for
fumigating greenhouses and for other like uses and for delivering liquid in the form
of spray or in a stream or streams as from a syringe the said apparatus being designed
more particularly for horticultural purposes.
In carrying out this invention we provide a vessel preferably of metal and of
cylindrical shape for containing liquid closed with the exception of two apertures at or
near the top and provided with a suitable handle for carrying it by. Connected to one
of the said apertures is an air pump which is constructed so as to force air into the said
vessel by preference as follows:-A tuhe furnished with a bucket or piston at its outer
end is connected to the said aperture and in this tube is a valve or valves opening
towards the said vessel. Free to slide upon this tube is a cylinder closed at one end,
the said tube passing through the other end.
When the said cylinder is moved outwardly air is drawn through the open end or
the cylinder and past or through the bucket or piston to the space beyond the same
the valve or valves in the tube meanwhile being closed, and when the cylinder is moved
in the opposite direction the air therein is forced through the tube into the vessel and
compressed between the top thereof and the top of the liquid therein.
Removably fixed to the second of the said apertures is an outlet pipe the outer end
of which is adapted to receive the nozzle or rose and inside this pipe is a smaller pipe
leading to or nearly to the bottom of the said liquid.
When the vessel is filled with liquid and the air pump cylinder is worked to and fro
the air which is compressed in the vessel as above described forces the liquid up the
said inner tube and the air also rushes along the annular space between the inner tube
and the inside of the outlet pipe and escapes at the outlet orifice with the liquid in the
form of spray.
By tilting the said vessel so that the liquid will flow along the said
annular space as well as up the inner tube the liquid will be delivered through the
nozzle or rose in a stream or in a divided stream as may be required.
When the apparatus is used for fumigating, a chamber containing the smouldering
tobacco paper or other fumigating substance, and having an inlet orifice at or near the
bottom and an outlet orifice furnished with a pipe at or near the top, is connected to
the outlet aperture of the vessel so that by means of the air pump air can be com-
pressed in the vessel and forced through the said chamber and smouldering fumigating
substance so as to cause a large and continuous volume of smoke to issue through the
outlet pipe.

COMPLETE SPECIFICATION.
Improvements in Apparatus for Fumigating or for Delivering Liquid
in the Form of Spray or in a Stream or Streams.
We, EDWARD EMBREY and ENOCH PRRY, trading together as Embrey and Parry,
of Mandril Tube Works, 86, New John Street West, Birmingham, Warwickshire,
Manufacturers, 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 :-
This invention consists in the herein described improvements in apparatus for
fumigating greenhouses and for other like uses and for delivering liquid in the form
of spray or in a stream or streams as from a syringe the said apparatus being designed
more particularly for horticultural purposes.

On the accompanying drawings
Fig. 1 illustrates in sectional side elevation the said apparatus as used for delivering
liquid in the form of spray;
Fig. 2 shews details of the same;
Fig. 3 shews the same apparatus as used for delivering a liquid in a stream or a
divided stream and
Fig. 4 shews the attachment for use with the said apparatus when fumigating.
In carrying out this invention we provide a vessel a preferably of sheet metal and
of cylindrical shape for containing water or other liquid closed with the exception of
two apertures marked respectively b and c at or near the top of the vessel a and
provided with handles d and e for carrying it. by. Connected to one of the apertures c
is an air pump which is constructed so as to force air into the vessel a by preference
as follows: An open ended tube f furnished with a bucket or piston g at its outer end
is removably connected to the aperture cand in each end of this tube is a valve marked
respectively (or one valve only may be used) opening towards the vessel a. Free
to slide upon the tube f is a cylinder i closed at the top, the tube f passing through
the lower end which latter is contracted to fit loosely on the tube.
When the cylinder i is moved outwardly (see Fig. 2) air is drawn through the
space between the open end and the tube f and past the bucket or piston g (or the
bucket or piston g may be made so that the air will go through a valve therein) to
the space beyond the same, the valves h¹ h³ in the tube f meanwhile being closed,
and when the cylinder i is moved in the opposite direction the air therein is forced
through the tube f past the valves h' ' into the vessel a and compressed between
the top thereof and the top of the liquid therein.
Removably fixed to the aperture 6 is an outlet pipe ; the outer end of which
is screw threaded or otherwise adapted to receive the nozzle k (or an ordinary
rose) and fixed inside this pipe j is a smaller pipe leading to nearly to the
bottom of the said liquid. The nozzle k is preferably bent as shewn so that it can
be turned round to direct the stream or spray in any direction.
When the vessel a is filled with liquid (see Fig. 1) and the air pump cylinder i
is worked to and fro the air which is compressed in the vessel a above the liquid
as above described, forces the liquid up the inner tube and the air also rushes
through the small hole m and along the annular space m' between the inner
tube and the inside of the outlet pipe j and escapes at the nozzle k with the
liquid in the form of spray. By tilting the vessel a (as shewn in Fig. 4) so that
the liquid will flow along the annular space m² as well as up the inner tube the
liquid will be delivered-through the nozzle in a stream or through a rose instead
of the nozzle k in a divided stream as may be required.
When the apparatus above described is used for fumigating the outlet pipe j is
removed and a chamber n (see Fig. 5) containing the smouldering tobacco paper
or other fumigating substance, and having an inlet orifice o at or near the bottom
and an outlet orifice p furnished with an open ended pipe 9 at or near the top is
removably connected to the outlet aperture 6 of the vessel a so that by means of

page_text: the air pump above described air can be compressed in the vessel a and forced
through the chamber n and smouldering fumigating substance contained therein so as
to cause a large and continuous volume of smoke to issue through the outlet pipe q.
The accompanying drawings illustrate what we consider to be the best way of
carrying our invention into effect but it is to be understood that the said invention
is not limited to the precise details illustrated as the same may be varied without
departing from the nature of our invention.
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—
1. In apparatus for fumigating or for delivering liquid in the form of spray or
in a stream or a divided stream as through a rose, the combination with the portable
vessel for containing the liquid of the herein described improved air pump arranged
for the purposes and substantially as hereinbefore described and illustrated by the
accompanying drawings.
2. In apparatus for delivering liquid in the form of spray or in a stream or a
divided stream as through a rose, the combination with the portable vessel for
containing the liquid and an air-pump for forcing air therein, of the outlet pipe j
furnished with the inner pipe and an air or liquid aperture m arranged substan-
tially as hereinbefore described and illustrated so that by merely tilting the vessel
when in use the liquid can be delivered either in the form of spray or in a stream
or divided stream as set forth.
3. The general combination and arrangement of parts constituting an apparatus
for fumigating or for delivering liquid in a stream or a divided stream as herein-
before described and illustrated by the accompanying drawings.
