Improvement in Apparatus for Fumigating both in Floricultural
and Horticultural Work.
ALFRED WILLIAM YOUNG Nurseryman and Florist, 137 Holmesdale Road,
South Norwood, in the County of Surrey, do hereby declare the nature of this
invention to be as follows:-
My invention consists of the information hereinafter described, riz.: two portable
caps or vessels made in cast brass metal, one with a cone or cylinder cast to it,
cach cap or vessel to have a screw union, also one for attaching the fumigater when
screwed together to an ordinary garden syringe, the syringe being the motive
power, only instead of drawing water, it shall draw up atmospheric air, and eject
same with force back through the fumigater.
It consists of a cast brass metal cap or vessel, about one inch long and about two
inches in diameter, one end open, and the other closed, the open end to have a
screw union, the closed end to have a short connecting piece of brass barrel, about
one inch long all in the one casting, made in the different size barrel of syringes
now in use, with a screw union for attaching same to syringe, also in the centre of
closed end there shall be a perforated hole, about one inch in diameter, with a
screw rim standing up inside, about one half inch, this also is in the same one
casting, then screw the connecting piece of brass barrel of the perforated end of
cap or vessel, on to the syringe.
The next and complete portion is another cast brass metal cap or vessel, about
two inches long, and about two inches in diameter with a screw at large end,
shaping off to the end to about one half inch in diameter, with perforated end
similar to a pepper box, with a small hole in centre of same, about the size of a
pen, inside this said cap or vessel is cast a cone or cylinder all in the one same
casting, size of said cone about three inches long, tapering from one inch to size of
a pea, or of just sufficient length so that the large end of cone or cylinder screws
on to the one inch perforated hole or screw rim of number one cap or vessel, so
that when this last cap or vessel is screwed on there shall be a direct and perfect
action only through the said cone or vessel into the cylindrical tube or syringe,
and the same back again.
Description of my invention is as follows:
Unscrew the end of number two
cap or vessel containing the cone or cylinder, charge said cone or vessel with
tobacco, then screw up again, light through hole at end, and work syringe, when
you draw up by suction the atmospheric air, thus igniting the tobacco, and ejecting
fumes of same back with force through the cone or cylinder only, hence out
through perforated end, or pepper box.
The object of making the fumigater in two portions is to charge, and clean.
My said invention offers the following special advantages, the fumigater being
made in various sizes of syringes now in use, and can be worked either as a
syringe or fumigater, by disconnecting the latter, and adding thereto the rose cap
of syringe as made and fitted.
It is a means for effectually destroying all known fly, insect, and blight which
attack plants, being able to apply it to the plant in any desirable position, or
space, and under the leaves where the insect so much frequent, thus effecting great
economy in working.

1, ALFRED WILLIAM YOUNG Nurseryman and Florist, 137 Holmesdale Road,
South Norwood in the County of Surrey 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:-
My invention consists in providing for use with an ordinary garden syringe
apparatus for fumigating both in floricultural and horticultural work, the said
apparatus being interchangeable with the rose or jet usually employed with a
garden syringe interchangeably.
The fumigating apparatus detached from the syringe with which it is employed
is shown in the accompanying drawing in which
Figure is a longitudinal section of the fumigating apparatus with screw cap
for attachment to the barrel of the syringe.
Figure 2 is a plan of Figure 1.
The cap A is screwed internally to fit the barrel of a garden syringe in the
same way that a rose fitting or a plain jet is attached as occasion may require
when the syringe is employed in Horicultural or horticultural work for watering
purposes.
Upon the cap AI make a barrel B having a perforated bottom C and fitted with
a perforated cap D. The barrel B is charged with tobacco or other herb capable
of producing the required noxious fumes during its combustion which is to be
maintained by the action of the piston in the syringe the tobacco or other herb
being lighted before screwing on the perforated cap D.
The complete apparatus may be as hereinbefore described in which case the
whole of the air passing into the barrel of the syringe traverses the charged
barrel B during the out-stroke of the piston of the syringe and again traverses
the charged barrel B to pass out by the perforated cap D in the form of smoke
during the instroke of the piston of the syringe.
In order to make the action of the syringe more easy than when the whole
charge of air has to enter and be discharged through the body of tobacco or other
herb contained in the barrel B I provide an auxiliary air inlet E controlled by a
valve F. By this arrangement part only of the charge of air taken into the
syringe at the outstroke of the piston has to pass through the tobacco charged
barrel B but the whole charge contained in the syringe is discharged through the
perforated cap D during the instroke of the piston, the valve F closing upon its
seating to prevent the passage of air and smoke outward by the air inlet E.
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 :
Fumigating apparatus for floricultural and horticultural work consisting of a
combustion chamber for tobacco or other suitable herb, attachable to a garden
syringe with or without an auxiliary air inlet passage controlled by a valve
substantially as described.
