PROVISIONAL SPECIFICATION.
Improvements in Means for Impregnating the Water or Liquid
Discharged from Syringes.
I, SAMUEL HOWARD STOTT, of the Lindens, Fulwood, Preston, in the County
of Lancaster, Agent, do hereby declare the nature of this invention to be as
follows:-
This invention has for its object to provide means for impregnating the water
or liquid discharged from the outlet end or nozzle of a syringe with substances
soluble in water such as those used for insect-destroying fertilizing and deodorising
purposes and consists in interposing between the outlet end of the cylinder or pump
barrel of the syringe and the nozzle or spray-producing device a chamber arranged
preferably in line with the cylinder. Into the said chamber through a suitable
opening or openings which may be opened and closed by means of a screw-down
cap or caps is introduced the impregnating substance or compound. The ends of
the chamber are made of sheet metal perforated with a number of small holes aud
the chamber may conveniently be made to screw on to the outlet end of the cylinder
and to have the nozzle or spray-producing device screwed on to its own outer end.
When the water or other liquid is sucked into the pump barrel in the usual way
(during its inward passage into the interior of the syringe) it becomes impregnated
with the material within the chamber and when it is forced out again (or during
its outward or return passage) it becomes still further impregnated or mixed with
the said material.

COMPLETE SPECIFICATION.
Improvements in Means for Impregnating the Water or Liquid
Discharged from Syringes.
I, SAMUEL HOWARD STOTT, of the Lindens, Fulwood, Preston, in the County
of Lancaster, Agent, do hereby declare the nature of this invention, and in what
manner the same is to be perforined, to be particularly described and ascertained
in and by the following statement :-
This invention has for its object to provide means for impregnating the water or
liquid discharged from the outlet end or nozzle of a syringe, with substances soluble
in water such as those used for insect-destroying fertilizing, and deodorising
purposes, and it consists in interposing between the outlet end of the cylinder or
pump barrel of the syringe, and the nozzle or spray-producing device, a chamber
arranged preferably in line with the cylinder. The ends of the chamber are made
of sheet metal perforated with a number of small holes, and the chamber may
conveniently be made to screw on to the outlet end of the cylinder, and to have the
nozzle or spray-producing device screwed on to its outer end.
In the accompanying drawings,
Fig. 1 shows partly in side elevation and partly in longitudinal section diffusing
apparatus constructed according to this invention.
Figs. 2 and
are detail views to a larger scale hereinafter referred to.
1 is the pump barrel of an ordinary form of garden syringe to the outlet or
discharge end of which is screwed a casing 2 that forms a mixing chamber 2ª to
hold the fertilizing, insect destroying, or other ingredient. The two ends of this
chamber are each made of a sheet 3 of fine wire gauze and a perforated plate 4 that

sheets of gauze and their supporting plates may be he'd in place as shown, one
sheet of gauze and its plate being placed between the pump barrel 1 and the casing 2,
and the other sheet amil plate between this ensing and its removable cap or cover 2".
In Figs. 2 and 3, which are respectively a face view, and a central section, one of
these sheets of wire gauze with its supporting plate is shown detached from the
apparains. The water or other liquid sucked into the pump barrel when the
piston is drawn to the immer end of its stroke by the handle G, may enter through
a hole 7 in the cap or cover 2, and through a cage 8 provided with a spherical or
ball valve 9 and as it passes through the mixing chamber, it becomes
impregnated with the material therein. When the water or other liquid is forced
out or discharged from the pump barrel by the piston, it will on its return passage
through the chamber 2ª become still further mixed with the impregnating material,
and he discharged through a nozzle 10, the valve 9 at this time being closed against
its seat in the cap 2 so as to close the hole 7. If the casing 2 be permanently
secured to the pump barrel, it may be charged with the desirel material through
an opening or openings formed in its side and normally closed by a screw cap or
caps. When however it is made removable from the pump barrel as in the
construction described and shown it may be simply removed from the pump barrel
for charging, or the cap or cover 2 may be removed from the casing for this
purpose.
Ålthough I prefer to employ in conjunction with a syringe having a mixing
chamber as above describes a nozzle 10 of the kind described and shown in the
Specification of another application for Letters Patent filed by me dated March 7th,
1890 No. 3632 and in which the issuing water is caused to meet an obstructing
medium such as the underside of a cap 11, any of the ordinary forms of nuzzle or
66 rose may be so employed.
"
Having now particularly described and ascertained the nature of the said inven-
tion, and in what manner the same is to be performed, I declare that what I
claim is :-
Apparatus for diffusing upon plants, fertilising, insect destroying, and other
compounds in liquid form, comprising a syringe the pump barrel of which has at its
outlet or discharge end a casing with perforated end walls forming a mixing chamber
to receive insect destroying, fertilising or other substance and through which water
or other liquid will pass on its way to and from the pump barrel, substantially as
described and shown.
