Claims.

My invention relates to apparatus for applying liquid poison to plants.

An important object of the invention is to provide apparatus of the above mentioned charac- 5 ter, which is adapted to apply a liquid insecticide to the cotton plant, for destroying the boli weevil, and which apparatus will apply the poison, to a considerable extent, to the undersides of the leaves arid branches. A further object of the invention is to provide apparatus of the above mentioned character which will bend the cotton plant forwardly, by engaging its top, without breakingor injuring the same, to permit of applying the poison to the under side of the leaves.

A further object of the invention is to provide apparatus of the above mentioned character which will feed the liquid poison by gravity, in a highly ecient manner, to the absorbent element or mop.

A further object of the invention is to provide apparatus of the above mentioned character which may be conveniently iiushed for cleaning the same.

A further object of the invention is to provide apparatus of the above mentioned character which is in the nature of an attachment to be mounted upon the beam of the plow or cultivator.

A further object of the invention is to provide apparatus of the above mentioned character which is both vertically and horizontally adjustable.

Other objects and advantages of the invention will be apparent'during the course of the following description.

In the accompanying drawing forming a part oi this application and in which like numerals are employed to designate like parts throughout the same,

bodying my invention,

Figure 2 is a side elevation, parts in elevation, of the attachment embodying my invention,

Figure 3 is a plan view of the same, and,

Figure 4 is a vertical section through the Vlower portion of the flexible hose.

In the drawing, wherein for the purpose of illustration is shown a preferred embodiment of my invention, the numeral 5 designates the beam of the plow or cultivator, equipped with the handle 6, as is well known.

My liquid applying apparatus is adapted to be installed upon the beam 5 and may be used when the cotton is being plowed or cultivated. My apparatus comprises a supporting bracket, which Figure 1 is a perspective view of apparatus emlected adjusted elevation by means of a set screw Il or the like. The vertical rod I0 is rigidly attached to an inverted U-shaped clamp I2, which receives the beam 5 and may be held thereon by a screw I3 or the like. The horizontal tube 1 slidably receives a horizontal rod I4, adapted to be clamped therein in the selected horizontal position, by a set screw I5 or the like. Rigidly attached to the free end of the horizontal rod I4 is a band I6, formed of strap iron or the like, and this band is preferably circular. The band has separated end portions or extensions I'I, provided with outwardly bulging intermediate semi-circular portions I8. The extensions I'I are adjustably connected upon opposite sides of the bulging portions I8 by bolts I9, carrying thumb nuts 20. Band I8 and its extensions are resilient. A

The band I6 is horizontally arranged and receives therein a vertical preferably cylindrical tank or reservoir 2|, having a cover 22, provided with a vent 22. The tank 2| nts within the band I6 and is rmly held therein by frictional engagement, when the inner winged nut 2U is suitably screwed up. The tank 2I has a lower downwardly tapering bottom 23, the upper large end of which is covered by a strainer 24. At its lower end, the tapered bottom 23 has a tubular coupling 25, to receive thereon one end of a flexible hose 26, clamped thereon by a ring 26". This hose is bent upon itself into a general U-shape, providing vertical arms 21 and 28. The vertical arm 28 has its upper end held between the outwardly bulging portions I8 of the extensions II.y By unscrewing the outer winged nut 20, the arm 28 may be removed from between the outwardly bulging portions I8. It is thus seen that the tank 2l and arm 21 form one arm of a U-shaped syphon, while the arm 28 constitutesl the other arm.

The intermediate curved or bent portion of the hose 26 carries an absorbent element or mop 29, surrounding the same, and having depending flexible absorbent elements or cords 30. A valve or petcock 3| is attached to the outer arm 28 near and above the line of sediment 32 in the curved or bent intermediate portion of the hose 26. This valve or petcock is preferably inclined and arranged near and above the body portion 29 of the absorbent element or mop, so that it discharges the liquid poison upon the body portion 29, as shown by the arrows.

The operation of the apparatus is as follows:

With the apparatus mounted upon the plow beam 5, as shown, the tank 2| is suitably illed with the liquid poison and the strainer 24 will prevent the passage into the hose 21 of large particles. Since the upper end of the arm 28 is at all times open to the atmosphere, there is no tendency to create a vacuum in the U-shaped hose 26, and hence when the valve or petcock 3| is opened, the liquid will discharge freely from the petcock. The liquid poison passing upon the upper or body portion 29 of the absorbent element is transmitted to the lower portion or cords 3U of the mop, which become saturated with the liquid. As the beam 5 is moved downwardly of the row of cotton, upon one side thereof, the U-shaped hose 26 engages the upper end or top of the cotton plants, bending them forwardly without breakage, and this action is followed by the cords 30 of the absorbent element or mop, which will accordingly apply the liquid poison, to a considerable extent, to the lower sides of the leaves of the plant. This is important, as it prevents the poison from being readily washed off by the rain. The valve or petcock 3| is located above the level of sediment, indicated at 32. When it is desired to clean the hose 26 and tank 2|, the upper end of the arm 28 is removed from between the outwardly bulging portions |8, which may be effected by unscrewing the outer Winged nut 20. The arm 28 is then horizontally arranged and Water may be poured through the tank 2| and hose 26, to flush and hence clean the same.

It is to be understood that the form of my invention herewith shown and described is to be taken as a preferred example of the same, and that various changes in the shape, size, and arrangement of parts, may be resorted to, without departing from the spirit of my invention or the scope of the subjoined claims.

Having thus described my invention, I claim:

1. .An apparatus for applying liquid poison to cotton plants or the like, comprising a support, a tank mounted upon the support for receiving the liquid poison, a generally U-shaped conduit having spaced arms, one arm being connected with the tank and the other arm being open near its upper end, a fiexible absorbent liquid applying member carried by the transverse portion of the generally U-shaped conduit, and an outlet device connected with one of said arms and arranged to apply the liquid poison to the absorbent element.

2.
