Complete Specification Left, 3rd Oct., 1898-Accepted, 5th Nov., 1898.
I, GEORGE FREDERICK STRAWSON, of Horley, Surrey, Manufacturer, do hereby
declare the nature of this invention to be as follows:-
This invention is for an improved spraying machine for potato crops or other
purposes.
It consists of a frame supported on a wheel axle and drawn or propelled by any
suitable means.
Secured to the frame is a tank to hold the liquid. The said
tank is fitted with a suitable opening and strainers at the top. A horizontal
spindle with beaters passes lengthwise through the tank and is suitably fixed.
One end of this spindle passes out at the end of the tank and has a bevel wheel
upon it.
A second bevel wheel to gear with the aforesaid wheel is fixed upon
a spindle at right angles to the first spindle and carried to the side of the machine
where it is operated by chain gear direct from the main shaft, and so keeps the
contents of the tank continually in motion whilst the machine works.
A suitable double action force pump actuated by gear from the driving wheels
is provided at the delivery pipe with a three way tap, so arranged that when the
pump is working the tap can be turned to send the liquid direct to the spray
nozzles or returned into the tank as desired.
Double spraying nozzles are attached by means of suitable tubes and supports.
These nozzles are arranged in a hollow metal case of gun metal or other suitable
metal or material and are arranged so as to turn on a tapering plug passing
through the metal form and so connected with the liquid to be sprayed.

An Improved Spraying Machine.
I, George FredERICK STRAWSON, of Horley, Surrey, Manufacturer, do hereby
declare the nature of this invention and in what manner the same is to be per-
formed, to be particularly described and ascertained in and by the following
statement:
This invention relates to an improved spraying machine and has for its object
to construct a portable machine which whilst being drawn along will by suitable
mechanism 'connected to the axle of the supporting wheels, actuate a suitable
pump. mounted upon the frame of the machine and connected to a tank or recep-
tacle for, containing the spraying liquid, and from which tank the pump draws
the liquid and forces it through suitable spray nozzles carried at the rear of the
machine. A device is also provided for keeping the contents of the tank always
agitated whilst the machine is moving.

Figs. 11, 12, and 13, are enlarged views showing more clearly the construction
of the spray nozzles.
1, are the members of the supporting frame upon which is mounted the tank 2,
constructed of any suitable material and provided with an opening in which is
inserted a strainer 3, for the purpose of straining the liquid as it is poured into
the tank. Within the tank is a longitudinal shaft 4, supported at one end by a
bearing 5, secured to the end of the tank upon the inside by rivets or other suit-.
able means and passing out at the rear end of the tank through a suitable
stuffing box and gland 6. At the end of the shaft is secured a mitre wheel 7, in
gear with a second wheel 8, mounted upon a shaft 9, carried by a bearing formed
at the upper end of the bracket 10, secured to the side member of the frame.
The shaft 9, has at its outer end a chain wheel 11, operated from the axle 12, of
the supporting wheels 13, 14, and which axle is carried by suitable brackets
secured to the side members of the frame, and to which axle is attached a larger
chain wheel 15, so that upon the machine being drawn by a horse or other means
the shaft 4, will be caused by the wheels and chain connected therewith to rotate
and the radial beaters or blades 16, secured to the shaft 4, will agitate the liquid
contained within the tank 2. Secured to the axle 12, and upon the opposite end
to that bearing the chain wheel 15, and inside the frame is a pinion 17, in gear
with and actuating a second smaller pinion 18, which pinion is carried by a suit-
able bearing carried by the side member 1. The pinion last referred to has pro-
jecting from its inner face a pin 19, shown dotted, Fig. 1, to which is pivotally
attached the end of the rod 20, the opposite end of which is secured to the short
lever 21, pivotally secured to the end of the bracket 22, bolted or otherwise
attached to the side member 1. A pin passes through the ends of the lever 21,
and rod 20, and has attached to it the end of the rod 23, the upper end of which
is attached to the pump rod 24. of the pump 25, carried by the supporting frame
of the machine, see Fig. 1. The pump 25, may be of any convenient type but
is preferably double acting and has connected to it a pipe or tube 26. leading
from the tank 2, see Fig. 3, from which it draws the liquid forcing it through
the pipe 27, from whence the liquid is either allowed to pass through the three
way cock 28, shown also in section Fig. 7, to the spraying nozzles, or it is returned
if desired through the tube 29, to the tank according to the position of the
plug 30. of the cock 28. The liquid is led by the tube 31, to the junction 32,
from whence it passes to the spraving nozzles 33 (the construction of which will
be hereafter more fully described with reference to Figs. 11, 12, and 13) and
which nozzles are carried by the tubes 34, secured by clips 35, to the telescopic
tube 36. carried by brackets 37, secured to the ends of the longitudinal members
of the frame, and which tubes are connected by T. or other convenient unions,
to the flexible tubes 38, leading from the junction 32. It will be seen from the
drawings that the tubes 34, are each provided at the upper ends with a cock 39.
see also Fig. 8, by which means it is possible to throw any one of the nozzles out
of action when so required. The telescopic tube referred to above is made up
of 5 sections, although more or less may be used, which, as illustrated in Fig. 5,

page_text: may be extended or retracted, the tubes being secured when the adjustment is
effected by the set screw 40, passing through the collar 41, and through the tube
to which the collar is attached. It is thus possible to effect any adjustment of
the nozzles 33, so as to suit the nature of the crop being treated."
Referring to Figs. 11, 12, and 13, in which are shown to an enlarged scale the
nozzles 33 aforementioned, it will be seen that there are two nozzles each having
a conical body 40, provided with a central channel 41, for the passage of the
liquid, a portion of the body being cut away as shown in Figs. 11 and 13, for
the admission of the liquid from the central opening 42, of the casing 43, to the
upper end of which is attached the tube 34. The ends of the conical bodies or
plugs 40, are secured to the casing by means of the screws 44, which pass through
the bosses 45, cast or otherwise formed upon the casing 43, and which lugs also
receive the ends of the plugs 40, as shown in Fig. 11. A washer of leather or
other suitable material is placed beneath the head of the screw 44, to form a tight
joint. The lower end of the bore of the casing 43, is closed by means of the
screwed plug 46, a leather or other washer 47, being placed under the collar 48,
of the plug to form a tight joint. The nozzle 33, is spherical and has formed upon
it at right angles to the plug a screwed nipple 49, to which is attached the cap 50,
provided with a central hole 51, for the discharge of the liquid as indicated in
Figs. 11, 12, and 13. The arrangement of the nozzles permit of the same being
turned at any angle so that the discharge from one nozzle may be caused to
impinge upon the ground and that of the other may be directed either directly
at a right angle to the tube 34, or at any other desired angle thereto according
to the growth or nature of the crop or surface to be treated.
Shafts 52, may be attached to the frame for drawing the machine along.
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:-
1. In a spraying machine for treating potato or other crops or surfaces a suit-
ably shaped reservoir for the spraying medium having agitators for keeping
the contents thereof mixed and actuated by suitable gearing driven from the axle
of the driving wheels, substantially as herein described and illustrated by the
accompanying drawings.
2. In a spraying machine for treating potato or other crops or surfaces the com-
bination of a suitable force pump for drawing the spraying medium from its
reservoir with spraying nozzles connected to the pump by suitable tubes, the
nozzles being secured to adjustable tubes supported upon a telescopic tube carried
upon the frame of the machine, substantially as herein described and illustrated
by the accompanying drawings.
3. In a machine for treating potato or other crops or surfaces the arrangement
and construction of the spraying nozzles whereby the jet of liquid may be directed
in any direction and a means whereby the discharge from any one set of nozzles
may be checked or stopped without interfering with the others, substantially as
described and shown by the accompanying drawings.
4. The combination and arrangement of devices forming a spraying machine
for treating potato or other crops or surfaces substantially as herein described
and shown by the accompanying drawings.
