Be it known that l, FERDINAND L. CAPES, a citizen of the United States of america, residing at Atlanta7 in the county of Logan and State of lllinois,haveinvented certain new and useful Improvements in Fruit-Tree Sprayers or VWagon-Power Tree-Sprayers, of which the 'Following is a speciticaiion, reference being had therein to the accompanying drawings.

This invention relates to spraying appara lus, and particularly to that class designed for spraying Afruit-trees and the like with so lutions t'or destroying insects.

One object ot' the invention is to provide n'ieans for storing pressure while the vehicle carrying the solution is in motion, so that the said solution may he forced` through the sprajfinghose when the vehicle is at rest. This is especially i'lesirable where the trees diller in size or an unusual ainountof the solution is required alv a single point-as7 for instance, when a tree or plant is unusually infested with insects-for it enables the operator to stop under such tree and direct the solution to such points as will prove most eflteetive.

A further object ol` the invention is to produce a device which will act in conjunction with receptacles, such as barrels, containing the solution in such manner that the receptacles may be emptied iu succession.

Furthermore, an object of the invention is to produce novel means of regulating the stroke of a pumps piston that the pressure in a tank, to be hereinafter known as the pressu re-tani 1,7 may be limited to any maximum pressure desired.

Finally, an object of the invention is to produce a spraying apparatus which will pos sess advantages in points of simplicity, durability, and efficiency, proving at the same time comparatively inexpensive to produce and sustain.

lVith the above and other objects in view the invention consists in the details of construction and in the arrangement and coinbination ol" parts to be hereinafter more fully set forth and specitcally claimed.

ln describing the invention in detail reference will be had to the accompanying drawings, forming part o t' this specification, wherein like characters denote corresponding parts in the several views, and in which- Figure 1 is a view in elevation of a vehicle with apparatus embodying the invention applied. Fig. 2 is a longitudinal sectional view of a portion of a pitman.

In the drawings, 1 denotes avehicle, 2 the wheels thereof, and 3 sprocket-wheels taking motion from the wheels 2. A crank-shaft 4 is journaled in suitable bearings at the rear of the vehicle and carries the sprocket-Wheels 5, and the sprocket-chains 6 connect the sprocket-wheels 3 and 5 for drivingthe erankshaft. Stationed on the vehicle is atank 7, having suitable outlet-s 8 at bottoni of tank, to which the si'naying-hose i) are attached. These outlets 8 are the only ones provided for the tank, for it is air-tight for the purpose ot` causing the air therein to gain increased pressure as liquid is forced therein through the medium of the pump l0. rlhe pump has a cylinder in which a piston l' reeiprocates, and the ()iliiicl \,1'lietd 1l has a packing-box l2 for the reception of the piston-rod 13. The branch pipes l-t of the cylinder lead to the tank 7 and are suitably valved to permit the fluid to flow only from the cylinder to the tank. The brauch pipes are connected to the cylinder and are so valved as to permit liquid to tiowonlyin one directionwviz., into the cylinder. The branch pipes 15 communicate with a pipe 16, having a detachable flexible extension 17. The extension terminates in a metallic tube 19, having a flared end provided with a strainer. The pistonrod is driven from the crank-shaft through the medium of a pitman, which is made adjustable for automatically regulating the stroke ot' the piston and the pressure of the contents of the tank. To this end the pitman is formed in three sections 21,22, and 23, the former being a tube connected to the pistonrod by a universal joint and having a longitudinal slot. The second section consists of a rod having an angular end 24, protruding through the slot in section 21. A11 adjusting-nut is threaded on the outer end of the section 2l, and a spring 26, encircling the said section, abuts the angular end 24 of the section 22 at one end and the adjustingnut 25 at the opposite end, and it Will be IDO readily seen that the tension of the spring may be varied Within certain bounds. The section 23 is slidable on the section 22, and the section 22 isprovided with a shoulder 26'. The section 23 is provided with an adjustingnut 27, and thespring 28, which encircles the sections 22 and 23, is confined between the shoulder and the adjusting-nut. The sections 22 and 23 are held together in any suitable manner, here shown by a lug 23, and when there is a maximum pressure in the tank the lug travels in a slot formed in the tube23. The section 23 is .connected to and takes motion from the crank-shaft, and when the pressure in the tank reaches a predetermined point the springs will yield and the sections of the pitman will telescope and the stroke of the piston will be diminished or nullitied, as the case may be, and as the pressure is reduced in the tank the length of stroke will increase.

The construction, operation, and adyantages will, it is thought, be understood from the foregoing description, it being noted that changes in the proportions and other details of construction may be resorted to without departing from the scope of the claims.

Having fully described the invention,what I claim as new, and desire to secure by Letters Patent, is

l. In a spraying apparatus, a tank adapted to contain liquid under pressure and having a spraying-nozzle in communication with its interior, a pump for forcing liquid into the tank, a pitman comprising sections telescopically connected, springs for holding the sections distended, means for regulating the tension of the springs and means connected with the vehicle-wheels for reciprocating the pit-I man.

2. In a spraying apparatus, an air-tight tank; means for drawing liquid therefrom, a pump for forcing liquid into the tank, a spring-pressed piston and means for adjusting the tension of the spring, for regulating the pressure in the tank.

3. In a spraying apparatus, a tank adapted to hold liquid under pressure, a pump for forcing the liquid into the tank, a pitman comprising three telescopic connected sections, springs for holding the sections distended, means for adjusting the tension of the springs, a cran k-shaft and piston-rod connected by the piston, and means for driving the crank-shaft.

4. In a spraying apparatus, a tank, a pump for forcing liquid 'into the tank, a fieXible connection in communication with the receptacle containing the liquid for conveying it to the pump, a pitman comprising a central and two end sections, said end sections being slidable on the central section, means for holding the section distended, means for regulatin g the resistance of the sectionnretainin g means and suitable gearing for reciprocating the pitman.

5. In a spraying apparatus, atank, apump for forcing liquid into the tank, a pitlnan connected to the piston-rod of the pump, said pitman comprisinga central section and two tubular sections` slidable thereon, an adjusting-nut on each of the tubular sections, springs encircling the sections and abutting the nuts at one end and fixed projections on the central section at the opposite ends and means for reciprocating the piston.

In testimony whereof I attix luy-signature in the presence of two witnesses. i
