M. SCHLING DANDELION KILLER Filed Sept. 50, 1925 INVENTOR ATTORNEY Patented Dec. 21, 1926.

PATENT OFFICE.

MAX SCHLING, OF NEW YORK, N. Y.

DANDELION KILLER.

Application filed September 30. 1925.

The invention relates to hand gardening implements, and is a device for expeditiously and effectively destroying dandelions or like weeds in lawns; and the object is to provide a device of this character whereby a predetermined, small charge of poisonous liquid will be administered and confined directly to each plant selected for extermination.

1n the accompanying drawings, forming part thereof;

Fig. l is a longitudinal section through one form of the lnvention, showing parts in the plane of the section principally in elevation;

Fig. 2 is a sectional end view taken on the line 2-2 of Fi 1;

Fig. 3 is a longitudinal section through another embodiment; and

Fig. 4. is an enlargement of the lower part of Fig. 3, showing the parts in another position.

The form of Figs. 1 and 2 will first be described. The device comprises a flask 2 of any suitable material to hold the liquid adapted to be held in the hand, and having an outlet at its forward or lower end. In the axial opening 3 at the outlet end, there fits slidingly with a liquid-tight joint the forward end of a longitudinal rod 4, which passes through the flask and has an operating button or handle 5 at its rear end. A cross hole 6 in the forward end of the rod forms a pocket calculated to hold the charge necessary for killing a plant.

\Vhen the rod is retracted, this pocket is brought into communication with the interior of the flask and becomes filled; and when the rod is released and is moved forward by a spring 7 the pocket is projected outward as seen in Fig. 1 so that its charge is dropped upon the plant. The spring normally holds the rod in this position, the rod being retracted by the pull of the fingers of one hand, which secures a purchase on a handle 8 on the rear end of the flask.

The outlet. is surrounded by a rim or wall 9, of materially larger internal diameter than the rod 4 and opening 3. This rim has a beveled lower edge 10 and is adapted to be pressed down and into the ground or plant the flask 2 has a fittin Serial No. 59.598.

so as to form a poison-administering chamber, to enclose the deposited charge and keep it from spreadin".

A plug 11 enables the flask to be refilled. In the embodimentshown in Figs. 3 and 4 12 screwed on its which fitting perforward end, removal 0 mits refilling.

This fitting has a transverse guide-way 13, and ports 14: and 15 out of alinement with each other, the port 14 communicating with the interior of the flask and the port 15 delivering into the outlet chamber 16. A slide 17 fits fluid tight in the guide-way and has a through hole or pocket 6*, which in one position registers with the port '14, and is out of register with the port 15, while in the other position it is in register with the port 15 and out of register with the port 14. A spring 17 holds the slide in one position, and a pivoted lever handle 18 at the side of the flask will move it to the other position. In the position of Fig. 3 the pocket 6 is filled; in the position of Fig. 4 it drops its charge. The dropping of the charge is insured by an air passage 19 in the fitting, with which the pocket hole 6 also communicates when it is in eommunication with the port 15.

What is claimed as new is: so

1. As a new article of manufacture, a dandelion-killer, the same being a hand gardening implement comprising a flask to hold a supply of an agent poisonous to plants, means on the forward end of said imso plement adapted to be pressed down upon a plant to form a poison administering chamber, the implement being formed with a passage between the interior of the flask and said chamber, and a member fitted to to reciprocate in fluid-tight contact in said passage, said member having means to .deliver a predetermined charge of the poisonous agent from the flask into said chamber.

2. As a new article of manufacture, a dan- 95 delion-killer, the same being a hand gardening implement comprising a flask to hold a supply of an agent poisonous to plants, means on the forward end of said implement adapted to be pressed down upon a plant 100 in form a poison arhninistering chamber, the implement being further formed with a passage between the interior of the flask and the upper end of said chamber, the chamber being enlarged relatively to the passage, and a member fitted to reciprocate up and down in said passage in fluid-tight contact therewith and provided with a peekel: arranged to be carried from an upper position in eemnmnieatirm with the supply to a lower position within the enlargementnl' said el'iamher sonons agent into said chamber.
