Improved Machine for Spraying Growing Potatoes, Turnips, and
the like, to Prevent Disease.
I, DAVID LIVINGSTONE BOWE, Bowmont, Dunbar, Potato Merchant, 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 relates to an improved machine for spraying growing potatoes,
turnips and the like, to prevent disease. The chemical solution is contained in a
tank or barrel mounted on wheels and drawn along the potato drills by horse
power or otherwise. I prefer to employ an iron tank which may be rectangular in
shape. Behind the tank is mounted a horizontal spraying tube preferably of copper
but I prefer to use two tubes extending out from each side of the tank. The spraying
tubes are supported by means of two upright side rods and an overhead rol, the
tank being between the side rods. Each of the side spraying tubes is provided with
four nozzles, roses or sprayers for the purpose of spraying four drills on each side of
the tank that is to say eight drills are sprayed simultaneously. The chemical
solution is fed into the spraying tubes by means of a pump worked from the axle of
the machine. The connection between the spraying pipe and the discharge pipe
from the pump is preferably by means of india rubber tubing; another piece of
india rubber tubing connects the outlet from the tank with an air chamber of
the pump.
In order to prevent the chemical solution settling I employ an agitator or propellor
inside the tank which is rotated by gearing from the driving axle.
Below the spraying pipe and running parallel therewith and preferably in advance
of the spraying pipe I mount a rod which strikes the haulms or tops of the potato
plant and thus allows the spraying tube to spray underneath and on to the stalks of
the plant as well as on the top of the leaves.
I adjust the height of the spraying tubes by so mounting them on the uprights
of the supporting framing that they can be raised or lowered as required.
Also in accordance with my invention when it is required to take the machine
through a narrow gate way or to bring the machine close to a wall, I so mount the
spraying tubes and the lower rod that they are capable of being turned upwards
into a vertical position, the arrangement being such as to enable this to be done is
by simply drawing out a pin at the inner end of the spraying tube which as aforesaid
is attached to the upright framing for supporting the spraying tubes.
I may provide the outer ends of the spraying tubes with caps so that a cleaning
brush or rod may be passed right through them for cleaning purposes.

Improved Machine for Spraying Growing Potatoes, Turnips, and
the like, to Prevent Disease.
I, DAVID LIVINGSTONE BOWE, Bowmont, Dunbar, Potato Merchant, 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 relates to an improved machine for spraying growing potatoes,
turnips and the like, to prevent disease.
But in order that my said invention may be more readily understood and easily
carried into effect I will proceed to describe the same with reference to the accom-
panying drawings in which
Fig. 1 is a rear view in perspective and
Fig. 2 a front view in perspective of my improved machine.
Figs. 3 and 4 are elevation and plan respectively to an enlarged scale, of the nozzles
or sprayers shewn in Fig. 1.
As shewn in the said drawings the chemical solution is contained in a tank or
barrel A mounted on wheels a and drawn along the potato drills by horse power
or otherwise. Behind the barrel A are mounted two horizontal spraying tubes B,
preferably of copper extending out from each side of the tank or barrel. The
spraying tubes B are supported by means of two upright side rods C and an overhead
rod c to which they are connected by adjustable tie rods c¹, the barrel A being
between the side rods C. Each of the side spraying tubes is provided with three or
four nozzles, roses or sprayers D, for the purpose of spraying three or four drills on
each side of the tank that is to say six or eight drills are sprayed simultaneously.
The said nozzles or sprayers D as shewn more particularly in Figs. 3 and 4 each
consist of a short tube D having a circular receptacle d at its end and provided
with a removable cap E through the opening e of which the chemical solution is
sprayed. The inlet F from the tube D to the receptacle d is situated at the one side
as shewn, in order to give the solution a circular motion whereby a more effectual
spraying of the same is obtained. The tubes D are provided with a joint d¹ to enable
the sprayers to be adjusted to any required angle. The chemical solution is fed into
the spraying tubes B by means of a pump G worked from the axle of the machine,
through the medium of the spur gearing G. The connection between the spraying
tubes and the discharge pipe g from the air chamber of the pump is preferably by
means of india rubber tubing g'; another piece of india rubber tubing 2 connecting
the outlet from the tank or barrel with the pump.
In order to prevent the chemical solution settling I employ an agitator or propellor
inside the tank which is rotated by bevel gearing H from the driving axle.
Below the spraying pipes and running parallel therewith and preferably in advance
of the spraying pipe I mount a rod J which strikes the hauims or tops of the potato
plant and thus allows the spraying tube to spray underneath and on to the stalks of
the plant as well as on the top of the leaves.
I adjust the height of the spraying tubes by so mounting them on the uprights
of the supporting framing that they can be raised or lowered as required.
Also in accordance with my invention when it is required to take the machine
through a narrow gate way or to bring the machine close to a wall, I so mount the
spraying tubes B and the lower rod J that they are capable of being turned upwards
into a vertical position. For this purpose I provide each spraying tube at the point b
with a joint upon which the spraying tubes are free to pivot. Or the rod J may, as
shewn, be hinged to the ends of the shafts of the machine so that when folded the
ends will lie in a position parallel with the shafts.

page_text: I may provide the outer ends of the spraying tubes with caps 6' so that a brush or
rod may be passed right through them for cleaning purposes.
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. The general arrangement, constructions and combination of parts constituting
my improved machine, for spraying growing potatoes, turnips and the like, substan-
tially as and for the purpose hereinbefore described and shewn in the accompanying
drawings.
2. In a machine for spraying growing potatoes, turnips and the like, the spraying
tubes B extending out from the side of the machine and adjustably connected to the
upright supporting rods C, and the adjustable tie rods in combination with the
flexible tubing connecting the ends of the spraying tubes with the pump, whereby
the spraying tubes can be adjusted to any height, retained firmly when in position and
be folded or placed in an upright position when not required, substantially as
herein before described and shewn in the accompanying drawings.
3. In a machine for spraying growing potatoes, turnips and the like, the agitator
or propeller inside the chemical containing tank or barrel, arranged and operated in
the manner, as described and shewn.
4. In a machine for spraying growing potatoes, turnips and the like, the rod J,
substantially as and for the purpose hereinbefore described and shewn in the accom-
panying drawings.
5. In a machine for spraying growing potatoes, turnips and the like, the nozzles
or sprayers D, arranged and operating as hereinbefore described and shewn in the
accompanying drawings.
