IMPROVEMENT IN MACHINES FOR SPRINKLING LIQUID POISON UPON VEGETATION.

Specification forming part of Letters Patent No. 222,831, dated Decen1ber 23, 1879; application filed August 13, 1879. I

To all whom it may concern:

Be it known that I, FRANK I. MARsn, of North Clarendon, in the county of ltutland and State of Vermont, have invented a certain new and useful Improvement in that class of Machines commonly called Potato-Bug Exterminators, of which the following is a specification.

My invention relates to machines for sprinkling vegetation with a liquid poison adapted to destroy the insects which prey thereon Without injury to the plants.

To this end my invention consists of a certain new construction. and combination of parts, which will first be clearly described in the specification, and then more specifically pointed out and defined'in the claims annexed thereto.

In the following description, reference is had to the drawings accompanying and forming part of this specification, in which- Figure l is a perspective view of a machine embodying my invention, a portion being broken away to show the interior of the can or reservoir for containing the poison. Fig.2 is a view,of the elastic compressible bulb, with the compressing devices and the automatic clamps for closing the eduction-pipe. Fig. 3 is an end elevation of the parts shown in Fig. 2.

A in the drawings representsthe can or receptacle for containing the fluid poison. This receptacle may be of any convenient form, al-

though the round reservoir shown is more easily made, and is, on most accounts, equal to any other form. This reservoir is provided with a tightly-fitting cover, .G, and has straps F F, attached in any convenient manner, so that it may be slung upon the person of the operator and carried easily.

Within the reservoir is placed a sack or receptacle, E, composed of textile'material, and so attached to the upper part or neck of the reservoir that when the cover G is removed easy access can be had to the mouth of the sack. Within the latter is placed the poisonous material used, either in crystals or in the pulverized form, the fluid or solvent being poured in afterward until the can is sufficiently filled.

When the mixture is merely a mechanical one, as in the case of common paris-green and water, the sack prevents the finely-pulverized powder from clogging the tubes and filling the fine perforations of the rose, while at the same time it allows a suffieient quantity of the powder to escape to impregnate the fluid.

When the poison is used in solution the sack retains the excess after the solution becomes saturated, and prevents it from being drawn into the eduction-pipe.

The fluid is discharged by means of a flexible tube, D D, terminating in a rose, B, having a large number of minute perforations. About midway of the tube 1) D is placed a compressible elastic bulb, B, having the wellknown alternating valves, whereby the liquid is drawn from the caninto the bulb and thence discharged through the rose l3.

Upon one end of the bulb B is placed a yoke, a, to which are pivoted compressors c a, partly surrounding the bulb at the point of its greatest diameter. These compressors are operated by the hand of the person using the machine, a moderate pressure causing them to contract or collapse the flexible bulb B and eject the fluid, while the elasticity of said bulb will cause it to expand, and at the same time open the pivoted compressors. The latter are extended beyond their pivotal point, and are provided at their extremities with pinching-lips b, which close forcibly upon the eduction-pipe D when the bulb is filled, but are opened by the contraction of the bulb, thus allowing the fluid to be discharged whenever desired, and

effectually preventing its accidental escape at all other times. Flanged guards f f are attached to each lip in order to prevent the tube 1) from accidentally escaping from between the lips, and, if desired, a spring might be attached to increase their power of compression;

but 1 have found by experience that the clasticity of the bulb B is amply sufiicient to operate the clamp and close the tube thoroughly.

By my invention vegetation which is infested by insects may be very efi'ectually treated and protected in a very short time, and with a great economy of the poison used. The simplicity and cheapness of the apparatus, together with the fact that it is impossible for the tubes and valves to clog or for the fluid to leak from the rose when the machineis not in operation, will enable this invention to supply a want which has long been felt by farmers and others.

leakage through the tube is obviated, as set forth.

2. The combination, with the reservoir A, of the closed sack E, suspended therein, the tubes D D, the rose B, bulb B, compressors 0 c, and the automatic clamp b b, as and for the purpose set forth.

The combination, with the can A, having interior suspended sack E, of the tubes D D, bulb B, compressors c 0, clamp b I), and guardflanges f f, as and for the purpose set forth.

In testimony whereof I have signed my name to this specification inthe presence of two subscribing Witnesses. V
