Improvements in Machines for Spraying Insecticides on Plants,
Trees, and the like.
I, ALBERT GARDNER PROVINE of Puyallup, in the County of Pierce, and
State of Washington, United States of America, Hardware Merchant, do hereby
declare the nature of this invention to be as follows:-
-
This invention relates to a machine for spraying insecticides on trees, plants, etc.,
in which spraying nozzles are so arranged and combined with pumps and other
appliances that the insecticide will be discharged under such pressure and conditions
as to be effectually applied to the plants, etc., in which provision is made for
adjusting the groups of nozzles laterally so suit the width of the plant rows, for
automatically maintaining the nozzles in vertical position on a side incline or
uneven ground, and for otherwise improving the efficiency of the machine.
The machine is adapted to be drawn by animal power and is supported on a
castor guiding wheel at front and at back on the rims of a drum which contains the
supply of insecticide and serves in lieu of a pair of wheels. The drum journal is
geared by sprocket wheels and belt with a shaft having cranks to which pumps are
coupled, a clutch being provided for throwing the crank shaft in and out of action.
The suction pipe leads through one hollow journal of the drum and extends down
within the drum to the lower part thereof. A vent pipe passes through the other
journal and leads up within the drum to near the top thereof and is prevented from
rotating. The suction pipe is connected by brauch pipes with the pumps which
are placed low down at each side of the machine. The delivery pipes from the
pumps connect with an air vessel and with a central pipe to which are connected
flexible branch hose pipes extending to either side of the machine where they
connect with swinging pipes extending fore and aft and more or less outwards
towards the rear where they terminate each in a vertical pipe provided with a
series of roses or discharge nozzles one above the other. The swinging fore and
aft pipes are closed at the front ends where they are loosely attached to the frame
so as to permit of motion of said pipes in the up and down or lateral directions.
To maintain the verticality of the nozzle pipes, when the machine is on a side hill,
the front ends of the swinging pipes have downward arms coupled by links with a
central bar pivoted to the frame and loosely connected with the support of the
driver's seat which is carried by a cranked supporting shaft extending fore and aft
and hung in bearings above the centre of gravity of the driver, so that his weight
will keep the seat horizontal and the latter will act through the connections above
described on the swinging and nozzle pipes, so that the latter will be prevented
from striking the trees or plants.
The nozzle pipes and swinging pipes are supported so as to permit of lateral
adjustment by radius arms or struts pivoted at their lower ends to the frame and
connected to the swinging pipes at their upper ends, their outward motion being
limited by adjustable tie rods or links, The vertical nozzle pipes are braced by
tie rods connected to their upper and lower ends and to the pivoted front ends of
the swinging pipes.
A
The pump-actuating crank pins are preferably adjustable in radius, by fixing
them in different holes in crank discs to vary the stroke of the pumps.
blow-off or safety valve is provided in connection with the delivery pipes and air
chamber.

Improvements in Machines for Spraying Insecticides on Plants,
Trees, and the like.
I, ALBERT GARDNER PROVINE, of Puyallup, in the County of Pierce, and
State of Washington, United States of America, Hardware 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 wheeled sprayers for applying insecticides to plants,
trees, and the like, and it has for its object to provide an improved machine of this
character, in which the spraying nozzles are so arranged as to discharge the
insecticide in such manner, and under such a pressure, as to effectually reach the
plants, or the like, and a further object is to provide for adjusting the groups of
nozzles toward or from each other according to the width of the rows of plants,
and also to provide for automatically maintaining the nozzles in vertical position
irrespective of any unevenness of the ground. Finally the invention embodies.
various details designed to promote general efficiency in the apparatus.
Reference is to be had to the accompanying drawings, forming a part of this
Specification, in which similar letters of reference indicate corresponding parts in
all the figures.
Figure 1 is a plan view of a sprayer constructed in accordance with my
invention :
Figure 2 is a side elevation :
Figure 3 is a rear elevation:
Figure 4 is a longitudinal sectional view of the hollow roller for containing &
supply of liquid insecticide; and
Figures 5 and 6 are detail views to be hereinafter referred to.
In constructing a sprayer in accordance with my invention, the frame-work A,
is of suitable form and strength to support the several parts, and is provided with a
pole or tongue for the attachment of the draft animals, the tongue having
preferably a castor wheel A', which will readily follow the lateral movements of
the tongue and guide the machine in turning. On the frame A, is suitably mounted
a hollow roller B, adapted to contain a supply of liquid insecticide, and provided
on one end of its axle with a sprocket wheel C, which is geared by a belt D, to a
sprocket wheel E, on the main shaft F, which latter is provided with the crank
disks G to which are coupled the connecting rods H, of the pumps I, the shaft
having a clutch F', operated by a lever F, for throwing the crank disks into and
out of operation. The pumps are mounted low on the frame A, for giving greater
steadiness to the machine. Branch pipes J, at the rear of the machine connect
the pumps with the suction pipe K, which latter extends from said pipes J, around
to one end of the roller B, and enters as at K', through the journal B', of the
roller, the suction nozzle Ĺ, being arranged within the roller, at the bottom and
provided with a suitable strainer. A veut pipe M, extends into the roller B,

page_text: hrough the opposite journal to near the top thereor, and is suitably supported at
the exterior against rotation, as at M¹.
The discharge pipe N, from each pump I, leads upward to the top of the machine,
where it has suitable connection with an air chamber O, and with the pipe P, to
which are connected sections of hose Q, and said sections of hose deliver to pipes R..
one of which ranges longitudinally of the machine at each side, each of the said
pipes R, having a closed front end which is loosely supported to permit certain
adjustment as hereinafter explained. The rear end of the pipe R, leads to and
supports the vertical pipe S (of which one provided at each side of the machine)
and the latter is provided with a series of roses or discharge nozzles T, one above
the other.
The front ends of the pipes R, are so formed as to permit a loose connection
with eye bolts U, or the like, on the frame A, as at R¹, and are provided with
depending arms R², with which are connected the links V, (Figures and 5) the
transversely-ranging links from each side of the machine being connected at about
the centre of the machine with a bar W, the front end of which is pivoted as at W'
to a transverse member or part of the frame A. The rear end of the bar W,
extends beneath the seat X, and a stud y, on the swinging supporting bar Y, of
the seat engages the bar W, the latter being slotted for the purpose. The
supporting bar Y, which extends horizontally beneath the seat and carries the
latter, is cranked, and extends upwardly from the seat and then rearwardly as
at y', where it is supported in bearings Z, formed on or secured to the brackets a.
Thus it will be seen that the weight of the driver on the seat ✗, will maintain the
latter in a horizontal position, the support Y being free to rock in its bearings, and
when the machine rises at one side, as for instance on a side hill, the seat will
maintain its horizontal position and, acting through the bar Y, links V, and arms R',
will rock the pipes R, and thus maintain the vertical pipes S, carrying the discharge
nozzles in the vertical plane, notwithstanding the tilting of the machine, with the
result that the pipes S, will be prevented from damaging contact with the rows of
plants or trees.
Provision is made for adjusting the nozzle-carrying pipes S, toward and from
each other as desired, by the following devices:-At the rear of the machine, near
each side, a bar b, is arranged, its lower end having a suitable pivotal connection
with the frame A, as at 6, and said bar at its upper end passes through a socket or
eye c, carried by the pipes R, adjacent to the vertical pipes S. The bar b, passes
also through one end of a horizontal bar d, which ranges transversely of the
machine and passes through a guide eye e, on the machine frame, and by moving the
bars 6 toward or from each other, the pipes R, and with them the nozzle-carrying
pipes S, will be adjusted accordingly, the pipes R, readily swinging on their
connections at U. The bars b, and d are formed in practice with a longitudinal
series of apertures for receiving split pins or cotters b³, f, which retain the parts in
the adjusted position.
The vertical pipes S are braced by the rods S', that are secured thereto at the
top and bottom, the opposite ends of the braces converging and being suitably
fastened to the front end of the pipe R, as at s.
The crank disks G, preferably are provided with two or more apertures gat
different distances from the centre, whereby the position of the crank pins may be
altered to increase or diminish the stroke of the pumps.
The machine is provided with a blow-off valve h, having a connection i, with
pipes J, and a connection j (Figure 6) leading to the discharge pipes and air
chamber.
The bunching or clustering of the discharge nozzles by arranging them on the
single vertical pipe at each side, affords the proper pressure, and this with the
vertical series of nozzles is efficient in reaching the plants. Also the general
structure of the machine with the adjustments specified, affords a proper equipment
for the intended service,
