Improvements in Spraying Apparatus for Potatoes, Fruit Trees, and
such like.
BURTON RICHARD PHILLIPSON, Engineer, of 10, Lower Baggot Street, Dublin,
and SAMUEL HUDSON PILLAR, Merchant, of 10, Lower Baggot Street, Dublin, do
hereby declare the nature of this invention to be as follows:-
According to our present invention we make a vessel to contain liquid which
vessel is carried on the back like a knapsack. From it we carry a delivery pipe
to a pump and air vessel, in which compressed air acts as a cushion to maintain
continuous flow. In one form the pump is attached to a stirrup upon which
the foot is placed, in another form the pump and air vessel are held in one hand
& the piston worked by the other hand of the operator. In some cases we use
the vessel containing the liquid as a pressure chamber and use an air pump held
in one hand & having the piston worked by the other to pump air into it to produce
the necessary pressure, in this and the former case the tube leading to the spray
jet, and the jet; are attached to the pump so that both are held in the same hand
of the operator.

Improvements in Spraying Apparatus for Potatoes, Fruit Trees, and
such like.
We, BURTON RICHARD PHILLIPSON, and SAMUEL HUDSON PILLAR, both of 10,
Lower Baggot Street, Dublin, in the County of Dublin, Engineer and Merchant,
respectively, 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 has reference to the method of creating pressure within machines
used for spraying potatoes, vines, and the like, and for distributing liquid from
such machines to the plants. In the method at present adopted the pump whether

page_text: for forcing air into the tank of the machine, or for pumping the liquid into an
air chamber is attached to the tank, which tank in those machines known as
knapsack machines, is carried on the operator's back. To this pump a lever is
attached which is worked by one hand, while the distributing pipe is manipulated
by the other.
The drawings set forth our apparatus as an elevation partly in section.
In these, A is a tank which can be made in any convenient shape and attached
to a man's back like a knapsack. It is preferably of copper or other non-cor-
rodible material. We have found it very desirable to cover this with wood
lagging, papier maché, or other like material. This tank is fitted with a filling
hole C which is closed air-tight by a screw stopper B.
A. cork or other stopper
could be used instead, but is not so convenient. D is the hand pump and E the
pipe to which nozzle is attached. Fa discharge cock or valve for regulating
the discharge of the liquid in pipe G. Pipe G is connected at H with flexible
pipe I. J is an internal pipe leading from the delivery of the pump to chamber A
at K. L is a branch from pipe I for conveying liquid from the bottom of
chamber A.
The mode of action is as follows:-
A can be either a stationary tank or on wheels with a long pipe I and J, or
it can be carried as a knapsack on the operator's back. He takes the pump D
on the pipe G in his hands, and for convenience the pipe J is passed through the
interior of pipe G, so that it can be held more conveniently in the hand. The
operator pumps in air by means of the air pump D. This forces air into the
cylinder A at K. This cylinder has previously been filled with the liquid to be
ejected on to the plants through the hole C and the lid B has been hermetically
closed. The air entering chamber A presses down the liquid forcing it through
the pipe L to the nozzle E which can be of any suitable form, either a rose or a
jet or a spreader. Valve F can be adjusted to regulate the flow of liquid or shut
it off completely. It will be seen that the operator can hold both the pipe G
with its internal pipe and the barrel of the pump D with one hand and can work
handle of pump with the other, the tube G being stiff and lying parallel with the
tube D, it appears to the eye as if the pump squirted the liquid direct like a syringe,
the liquid however coming from the nozzle E and not from the end of the pump.
If the chamber A be stationary or placed on wheels the pipes J and I are
extended by additional pipes being attached to them.
Having now particularly described and ascertained the nature of our said
invention and in what manner the same is to be performed, we declare that what
we claim is:
-
1. The combination in machines for spraying potato plants vines and the like,
of a pump to be held in the hands and a knapsack to be carried on the back with
india rubber or other tube of like flexible material connecting the same.
2. In a spraying machine, the combination of an air pump for creating pres-
sure in the reservoir for liquid and a jet for the delivery of the liquid attached
to said air pump.
3. The combination in a spraying machine of an air pump, a pressure chamber
and an india rubber or other tube of flexible material connecting the same instead
of the pump and chamber being rigidly attached as heretofore.
4. The combination in spraying machines of an air pump, a pressure chamber,
an inflow pipe for air and an outflow pipe for liquid, the pipes being made of
flexible material substantially as described.
5. An air pump for operating a spraying machine connected with the pres-
sure chamber by freely flexible connections and so constructed that the operator
in working holds the barrel of the pump with one hand and the handle of the
plunger with the other.
6. The combination with spraying machines of a two way flexible tube so

page_text: arranged that air is introduced to the pressure chamber through one way, while
liquid is discharged from it by the other way.
7. The spraying machine having a knapsack capable of withstanding rough usage
constructed and arranged as herein set forth.
