Toallwhomitmayconcem:

Be' itknown that I, Aimirrn A. S'rUnro dent of S nor, in the county of, Washburn and tate of Wisconsin, have invented a new an! useful Improvement in Spraying Devices, of which the following is a full, clear, and exact'description.

My invention relates to dev ces for use in spraying a liquid upon plants in a field, and it consists in thecombinations, constructions, and arrangements herein described and claimed An object of 'my-invention is to PIOVIdG an attachment for a movable sprayi ng ma chine'which will co-act with the latter to bend standing plants at the time a liquid is discharged u on such. plants.

A further 0 ject of my invention is to provide an attachment of the character described that can be adjusted relatively to a movable sprayer to which attached for operative engagement with plants of various heights.

A further object of my invention is to provide an attachment having means for flexibly attaching the same to a vehicle, whereby the attachment is capable of a limited movement verticalllfy to compensate for irregularities in the su ace traversed by the vehicle. 0

A further object of my invention is to provide an attachment of the character described that is adapted for use in connection with a movable spraying machine of an ordinary construction without any extensive changes, if any, in the constructron'of the latter bein required.

Other ob ects and advantages w1ll appear in the following specification, and the novel features of the invention will be articularl pointed out in the appended. c aims..

y invention is illustrated in the accompanying drawings forming part of this application, in which The figure is a pective view of a sprayer equipped wit my invention.

. ferring now to the drawing, 1 denotes a vehicle rovided with a tank 2 adapted to receive a iqliid. A delivery conduit 3, supported on t e frame of the vehicle, communicates with the tank 2 and leads to a manifold 4 which is provided with a plurality of spaced apart nozzles 5. A pump 6 is operativel connected by a tube 7 with the delivery condiiit 3 and may be perated to cause the and form 'no side of the frame beyond liquid from the tank 2 to be discharged from the nozzles 5 underpressure. The parts described so far are ordinary in construction so far as they cooperate with the parts which will now be described.

part of my invention except in In carrlyl'ingout my invention, I rovide a frame av ing substantially para! el end members 8 and 9 connected at one end by a transverse. member 10., A

piece of wire length of these members, as shown. The

wire screen 11 is attached 'to the end memscreen 11, or like material, is cut to a size bers 8 and 9 and to the connecting member 10 by any suitable. known means, such as staples or the like, no means being shown in the drawings, and may be clamped between the end members 8 and 9 and the transverse member 10 at certain points, as shown.

A pair of spaced apart attaching members 12 and 13 are secured to the transverse member 10 in parallel relation with respect to each other and to the frame members 8 and 9. These attaching members extend at one the corresponding ends of the frame members 8 and 9. A plate 14 formed with an eyelet 15 is attached to the frame 12 intermediately ofits length. A screw eye 18 is attached to the member 12 adjacent to the end thereof that projects beyond the correspondin end of the frame member 8. The attaching member 13 likewise carries a screw eye 19' adjacent to the end thereof that ro'ects beyond the correspond' end of t e me member 9. Similar flexi lemembers, such as the chains which are indicated at 20-20, are attached at one end to the eyelets 15 and 17 and are detachably secured at their other ends to means, such as the hooks 21-21, which are carried by the frame of the vehicle. Other flexible connecting means, such as the chains 22-22, connect the eyelets 18 and 19 with hooks 23-23 carried b the frame of the vehiclein positions ad acent to the hooks 21-21 and slightly below the level of the latter, as clearly shown in the drawings.

From the foregoing descri tion of the various parts of the device, t e operation thereof may be readily understood. The frame of the attachment is initially adjusted at a desired height above the surface to be traversed and at a desired inclination from the horizontal by adjusting the effective lengths of the chains 20--20 and 22--22.

storage tank 2 will be discharged through the screen upon plants 24: which are arranged in rows in a field. The inclination of the screen 11 from the horizontal is such that the edge thereof nearest to the vehicle 1 will not engage the plants, since the lants might beinjured by such a contact.

owever, the screen 11 will float on the plants and the weight of the screen andof its supporting frame will cause the plants to be bent over at the time the liquid solution from the tank 2 is discharged thereon. It will thereforebe manifest that all portions of the plants will be subjected to the action of the solution used and in consequence insects and parasites clinging to the under surface of the plant will be drenched with the spraying solution. When an ordinary spraying device is used, the plants are not bent over at the time the solution is dis{ charged and therefore the insects and parasites on the under surfaces of such plants are not subjected to the action of the spraying solution; Another advantage of my dewhich I am aware, without any extensive 4 changes, if any, in the construction of the latter being required.

, -I claim:

1. The combination "with a vehicular spraying machme having a plurality of nozwardly, of a flat perforate member, and means for adjustably attaching the perforate member to the machine to support the memher in a desired position between the nozzle orifices and the surface to be traversed by the machine.

2. The combination with a vehicular spraying machine having a plurality of noz-' zles arranged to discharge a liquid downwardly, of a flat perforate member, and means for adjustably and flexibly attaching the perforate member to the machine to support the member in a desired position between the nozzle orifices and the surface to be traversedby the machine.

3. The combination with a spraying machine, a wire screen frame, chains secured to the middle and sides of said frame and being secured to said machine for holding the frame in a substantially horizontal plane, the end of said frame disposed next to the machine being raised higher with respect to the supporting' surface than the other end, and

-zles arranged to discharge a liquid down-'- i spray nozzles communicating with said machine and terminating above said frame, said frame being adapted to' be moved upwardly by the plants over which the frame travels.
