which may be pulled by a horse, and which 5 will be convenient in getting the machine tl. 'ough tight places when necessary. The invention also aims to provide a device of 'this nature which it is easy to pull along' a row and to make the sharp turn at the end l thereof so as to pull it down the next row.

An important object of the invention to provide a sprayer of this nature having a pumping mechanism operable by the Wheels of the supporting` structure so that the solu- 15 tion to be sprayed may be placed in a tank under pressure whereby it may be sprayed from a hose or the like most effectively.

A further important object of the invention is to provide a sprayer of this nature 20 qwhich is exceedingly simple in construction,

inexpensive to manufacturaecient and reliable in op ion, strong, dur ble and not likely to readily become out of order, and otherwise Well adapted to the purpose for which it is designed.

iVith the above and numerous other objects in view as will appear as the description proceeds, the invention resides in certain novel features of construction, and in the combination and arrangement of parts as will be hereinafter more fully described and claimed.

In the drawings Figure 1 is a side elevation of the sprayer 35 embodying the features of my invention.

Figure 2 is a top plan view thereof. Figure 3 is a longitudinal section through the pump.

Figure l is a fragmentary elevation of the l low pressure-tank.

Figure 5 is an elevation of a disc rotatable with the shaft.

Figure 6 is an elevation of a ring' rotatable with the Wheel, and 45 Figure 7 is a section through one of the check valves.

Referring to the drawing in detail, it will be seen that 5 designates a frame, mounted on the brackets 6, through Which extend the crank shaft 7. the ends of which are mounted in Wheels-8. A suitable tongue or other draft means 9 extends forwardly from the frame in order that the same may be drawn by ho ses or the like, A plate 10 is mounted on the forward portion of the frame 5,

and supports a high pressure tank 11. A lore pressure tank 12 is mounted on the rear end of the frame being held invplaceby straps 13 or any other suitable means.A A. puinp cylinder 14: is mounted on the plate 10 Ge immediately below the high pressure tank 11. PipesA 15 lead from the ends of the cylinder 14 to the bot-toni portion of the high pressure tank 11 and have check valves 16 therein. Pipes 17 connect with the other G5 end ofthe cylinder 11i and have check valves Y 15.1, therein. The' `check Valves`16 allow the passage of flu-id from the cylinderl-l only, while the check valves 18 allow Vthe passage' fluid t'oivar'd the cylinders.A The pipes 17. o are connected toa coupling 19 conneeted'by pipev section 2O to the lon'7 pressure tank 1Q; ipiston 21 is reciprocated in the cylinder' 1lbyVv a piston rod 22 extending through the stufng bos: at one end of the cylinder 1.4.' 75 This rod 22 extends rearwardly under the frame and its end isr slieable through a bracket An arm 25 is fixed rigidly to the piston rod 22 and is pivotally connected to a connecting rod 26 which is operable by the crank of the crank shaft 7. A. pipe 28 is extended bet-Ween the tanks 11 and 125 and has a safety valve 29 mounted therein, the specific structure of which is shown to advantage in Figure 7. A partition 30 is pro- 85 vided in the valve 29 and is provided with a valve seat for receiving the valve disc 31 provided with the stem 32 movable in the pocket 33 of a cap Se. A spring 35 is disposed about the stem 32 and tends to hold the valve disc 81 normally closed. The pump is adapted to deliver to the tank 11 about four times as much fluid as is necessar v and therefore, there Will be a considerable overflow going through the pipe 28 05 which will maintain the safety valve open or partially open, and this overflow fluid Will agitato the fluid already in the tank 12 to keep it well stirred up, thereby allowing a considerable economy in the use of the spraying fluid.

rlhe end portions of the axle shaft 7 are provided with grooves 37 and discs 38 are receivable on these axle shafts. The hubs 39 of the discs 38 have bolts l.LO threaded therethrough so as to be engageable With the grooves 37, thereby keying the disc to the shaft. Therhubs of the Wheels 8 carry rings Ll1 provided with interior teeth 42 which are engageable by the paivls 43 projecting from the periphery of the discs 38. By loosening up on the bolts Ll0, the discs may be moved out of the rings and the wheels will be free to rotate without the shaft. However, when the -discs 38 are moved into the rings and the bolts tightened up7 the crank shaft 7 operates with the wheel, thereby causing reciprocation of the piston 2l in the cylinder' le and forcing the spraying material from the lower pressure tank l2 into the high pressure tank ll and placing the same under pressure so that it may be forced through a suitable spraying hose or the like. The safety valve has its spring so tensioned that the liquid will not iiow from the high pressure tank to the low pressure tank unless the pressure becomes great enough to overcome the tension of the spring.

lt is thought that the construction, operation, and advantages of this invention will now be clearly understood without a more detailed description thereof. It is desired however, to point out that the present embodiment of the invention has been disclosed merely by way of example and that numerous changes in the details of construction, and in the combination and arrangement of parts may be resorted to without de-l parting from the spirit or scope of the invention as hereinafter claimed or sacrilieing any of its advantages.

Having thus described my invention, what I claim as new isz*- In a device of the class described, a wheeled structure of the type wherein two wheels are utilized having their axes aligned transversely under an intermediate portion of the structure, a crank shaft fixed to rotate with the wheels and constituting the axle of the wheeled structure, a connecting rod engaged with the crank of the shaft7 a pump suspended below the forward end of the wheeled structure, a piston in the pump, a piston rod extending from the piston, a bracket depending from the rear portion of the wheeled structure, said piston rod being slidable through said bracket, a rigid arm depending from the piston rod and engaged with the connecting rod, a pair of tanks on the wheeled strueture,one at the forward end thereof, and one at the rear end thereof, means connecting the tanks with the pump in order that fluid may be passed from one to the other and put under pressure in said other7 and a pipe connecting the two tanks and having a check safety valve therein for allowing passage of liquid from thetank to which the fluid is forced by the pump when the pressure becomes excessive therein.

ln testimony whereof I affix my si gnature.

RICHARD GARLAND.
