An Improved Spraying Implement for Spraying Cereal and other
Field Crops.
I, ALFRED NAYLOR PEARSON, of Rathmines Road, Hawthorn, near Melbourne
in the Colony of Victoria, Inventor, do hereby declare that the nature of my inven-
tion for "AN IMPROVED SPRAYING IMPLEMENT FOR SPRAYING CEREAL AND
OTHER FIELD CROPS" and the manner in which the same is to be used are
particularly described and ascertained in and by the following statement :—
The practice of spraying growing crops with fungicide and insecticide solutions
so as to kill those fungoid and insect parasites, such as rust and caterpillars, which
do great injury to cultivated plants, has in recent years been growing slowly into
favour, but with the spraying contrivances heretofore in use it has been possible to
treat only a comparatively narrow strip of the crop at one time and no contrivance
has been in use whereby full grown cereal crops could be economically sprayed.
This defect seems to have been due to the fact that the idea of using delivery
pipes of considerable length, such as 50 or 100 feet has not previously been
entertained, probably for one reason that it has not been seen how such pipes could
be conveniently and simply supported and moreover the idea of placing the
delivery pipe low down near the ground as in ordinary street watering carts has
generally been associated with such machines; but with machines so constructed
the pipe would obviously come in contact with the crop and be liable to injure it.
The essential feature of my invention consists in a long horizontal delivery pipe
of, say from 50 to 100 feet in length supported at a convenient height above the
floor or body of a vehicle, partly by rearwardly projecting arms and partly by a
standard or mast and tie rods, said pipe being fitted with cyclone or other nozzles
at suitable distances apart; a large barrel, tank or other receptacle being likewise
mounted upon the vehicle to contain a supply of the disinfectant or other liquid
which it is required to deliver on to the crops in the form of fine spray; a pump
being also provided to enable such liquid to be forced through the nozzles in the
comparatively long horizontal pipe above referred to, said pump being worked in
any convenient manner, say for instance either by hand or by gearing connecting
its handle with one or other of the "bull" or drive wheels of the implement.
A modification of this invention has been devised for the purpose of enabling the
under sides of the leaves of root and other low crops to be sprayed without running
any risk of injuring them by the main horizontal pipe above referred to.
Said modification consists in providing said pipe with a number of curved rear-
wardly projecting tubes fitted with nozzles adapted to deliver the spray upwards
and rearwards and arranged a few inches above the ground and so as to travel
between the rows of crops, as will be well understood.
Another modification of my invention consists in the employment of a narrow
vertically adjustable land wheel near either of its ends for supporting the main
horizontal delivery pipe instead of using the standard or mast and tie rods above
described.
Referring to the accompanying drawings,
Figure 1 is a rear elevation, and

invention.

The same letters of reference refer to the same parts in all the figures.
A represents the long horizontal delivery pipe which as above mentioned is
supported by arms a projecting from the body or framing of an ordinary or other
cart or vehicle, as clearly illustrated in my drawings.
The pipe is constructed in sections of convenient length, which may be unscrewed
and packed away in the cart when the implement is not in actual use.
This said delivery pipe is fitted with projecting nozzles B at regular intervals,
said nozzles being of any preferred construction, such for instance as those known
as the "cyclone" nozzles.
The arms a for supporting the pipe A are fixed in such a way, either by pivots or
otherwise, to the side of the vehicle as to enable the pipe A to be raised or lowered
to any height that may be required. This operation can readily be effected by
shortening or lengthening the ties c which may be made of either thin rods, wires,
or chains, and which extend down from the upper part of the mast or standard C,
as shown, said mast or standard C being fixed to the back of the cart in any
convenient manner.
The delivery pipe A is preferably supported in the upper ends of the arms a in
such a manner as that it can be turned round and thus cause the nozzles B to
project either up or down, forwards or backwards, as may be found most desirable.
I prefer to employ the well-known cyclone nozzles, that is, those having a circular
chamber into which the liquid to be delivered is fed tangentially by means of a pipe
or passage, and from which chamber there is a conical delivery hole arranged
centrally with said chamber so that the liquid revolving rapidly in this latter will
continue to revolve as it issues from said hole, and spreading outwards by reason of
the conical sides of said hole will be delivered in the form of fine spray.
The arrangement of the receptacle D for the reception of the liquid to be
delivered by my improved spraying apparatus and the pump E for drawing said
liquid out of said receptacle and forcing it through the delivery nozzles B will be
varied according to circumstances, and said pump can of course be operated in any
manner found most convenient. For instance, its lever or handle e can be connected
by a rod to a crank pin F upon a revolving shaft turned by chain gearing fl
clamped on to the spokes of one or other of the wheels of the vehicle, as clearly
illustrated in Figure 1.
According to the modification illustrated in Figures 3 and 4, the delivery
nozzles B are connected to the main horizontal pipe A by comparatively long
curved branch pipes B' which are so arranged that the spray is directed upwards
on to the under surface of the leaves of root and other low crops which grow near
the surface of the ground. By this means said crops would not be liable to be
injured by the horizontal pipe above referred to, because it would be fixed at a
height above them, and although the curved pipes leading therefrom to the
delivery nozzles B would be long enough to reach within a few inches of the ground
they would pass between the rows of plants without injuring the foliage.
In the modification shown in Figure 5 the horizontal delivery pipe is supported
by a narrow adjustable land wheel c near each of its ends instead of by the tie rods
and mast or standard shown in the preceding figures.
Having now particularly described and explained the nature of my said
invention and in what manner the same is to be performed I declare that what 1
claim is:
First. In an implement for spraying cereal and other field crops the combination
with a long horizontal delivery pipe (such as A) fitted with discharge holes or
nozzles (such as B) and supported on a vehicle at a convenient height above it by
suitably arranged arms and tie rods of a receptacle (such as D) for containing the
liquid and a pump (such as E) or its equivalent for forcing it out of sai
of said holes or
21

purposes herein described and explained and as illustrated in the accompanying
drawings.
Second. In an implement for spraying cereal and other field crops the com-
bination with a horizontal delivery pipe (such as A) passing through the upper
ends of a pair of arms (such as a) of a vertical mast or standard (such as C)
secured to the back of the vehicle and fitted with ties or chains for supporting said
horizontal pipe, said supporting arms being pivotted or otherwise connected to said
vehicle so that they are free to move either up or down as required, the whole
being constructed and arranged substantially as and for the purposes herein described
and explained and as illustrated in the accompanying drawings.
Third. In an implement for spraying cereal and other field crops the combination
with a horizontal delivery pipe (such as A) supported by adjustable arms and tie
rods at the back of a cart or other vehicle provided with a receptacle for the
liquid to be delivered of a series of curved rearwardly and downwardly extending
tubes (such as B') each fitted at its end with a nozzle adapted to direct the
liquid upwards and outwards, substantially as and for the purposes herein described
and explained and as illustrated in Figure 3 of the accompanying drawings.
Fourth. In an implement for spraying cereal and other field crops the combination
with a long horizontal delivery pipe (such as A) of a narrow vertically adjustable
land wheel (such as c) near either end thereof, said pipe being provided with
delivery nozzles and connected with a receptacle supported on a vehicle and con-
taining the liquid to be delivered, the whole being constructed and arranged
substantially as and for the purposes specified and as illustrated in Figure 5 of the
accompanying drawings.
