SPRAYING APPARATUS.

To all whom it may concern:

Be it known that I, CARL Rnlonnnr, a citizen of the United States, residing at North Yakima, in the county of Yakima and the State of Washington, have invented new and useful Improvements in Spraying Apparatus, of which the following is a specification.

This invention relates to an' automatic regulator cut oil and safety valve for power spray pumps.

The object of the present invention is to provide. an automatic liquid regulator for power spray pumps, which will control the spraying liquid, when the spraying apparatus is in operation and which will also maintain a constant pressure of the spraying liquid, said sprayin liquid and pressure being predetermine means being provided for regulating said spraying liquid and pressure.

A further object of the invention is to provide meansfor cutting oh the supply of liquid to the pump when the nozzle is cut off, allowing the pump to run free, thus reducing wear and saving fuel, the cut oil acting as a safety valve for the pump.

With the foregoing and other objects in view which will appear as the description proceeds, the invention resides in the com bination and arrangement of parts and in the details of construction hereinafter described and claimed, it being understood that changes in the precise embodiment of the invention herein disclosed can be made within the scope of what is claimed without departing from the spirit of the invention.

In the drawings-Figure 1 is a sectional view, the valve being open. Fig. 2 is a. similar view with the valve closed. Fig. 3 is a perspective view, diagrammatic in character, of a spraying apparatus embodying this invention.

In the drawings, 10 designates the body of the regulator, which forms the cylinder 14 having the inlet 11 which connects to thesupply tank 4, and the outlet 12 which connects to the spraying devices.

The contracted portion 15 at the upper end of the cylinder 14, 'forms the seat for the valve 16 which is a continuation of the piston 17 To prevent any liquid from passing through valve when closed, it is fitted with the leather disk 35, held in place by the washer 34, and nut 33; and for preventing liquid from passing around piston 17,

the leather disk 36 is held inplace by the washer 37 and screw 38. The reduced portion 16 of the piston 17 which forms the valve, is to allow for a free passage of the of the body 10, said casing housing the rod 18, spring 30, etc. The sleeve 22 which is the stem of the hand Wheel 26, is adjustably supported byscrewing into the upper end of the casing 21. The sleeve 22 forming a space for the freeworking of the rod 18. Attached to the rod 18 by pin 32, or other means so as to move with it, is plate 24, which is the seat for the lower end of the coil spring 30. The upper end of the spring 30 rests against the plate 25 which is similar to the plate 24, but loose from the rod 18, and is held in place against the end of the sleeve 22, by the'spring 30.

The spring 30 exerts a pressure on the seat 24 attached to the rod 18, thus forcing the piston 17 downwardly in the cylinder 14. The amount of pressure with which the. said piston is forced downward, is regulated by' turning the hand wheel 26 thus causing more or less compression in the spring.

On the lower end of the body 10 and forming the end of the cylinder 14 is screwed the cap 28 with the threaded pipe connection 27 for connection to the chamber of the spray pump.

The operation of the apparatus is as follows: Normally the tension in the spring 30 holds the piston 17 to the lower end of the cylinder 14, thus leaving the valve open.

When the spray pump 6 is started, the liq-I the valve 16 thus the supplyof fluid is imfluid regulation at all times, when the operpump will also effect a saving of fuel and is forced into the lower end of cylinder 14, such liquid forcing the piston 17 upwardly into the cylinder 14 against the pressure 6X. erted by the spring 30; thus tending to close the valve 16 and cut down the amount of spray liquid allowed to flow from the supply tank 4 through the valve 16 to the spray pump 6. The greater the pressure of the spray liquidfrom' the pump 6 the nearer closed the valve 16 will be. lVhen the spraying nozzle 9 is cut ofl", by closing the valve 9 more liquid is conducted to the lower part of the cylinder 14, due to the immediate slight increase in pressure of the spraying liquid. The incoming liquid contacts with the piston 17 forcing the same upward against the action of spring 30 and closing mdiately cut off when the nozzle 9 is cut 0 Attention is called tothe fact that the tension of the spring 30 can be regulated through the medium of the sleeve 22 which is operated by the hand wheel '26, so that any desired pressure may be maintained.

The manyadvantagcs of a device of this character will be clearlyapparent as it Will be noted that the same provides an effective ator of the spray pump 6 is using the spray lg uid through the nozzle 9. It is also an e ective fluid cut off when the spraying nozzle 9 is out OK and acts as a safety valve for they spray pump 6 at all times. The cutting o of the spray liquid from the unnecessary wear on the engine and pump by allowing them to run free. .It will also be seen that the structure is such as may 1 be easily and economically manufacturedl and the various parts readily assembled, and i 'that the device may be applied to spraying 1 inlet port being connected with said source of supply and the outlet port being connected with said pump, whereby the latter is arranged to draw liquid through saidpaslsage from said source of supply; a valve mounted in said valve-casing and arranged to control said passage; a spring which normally presses upon said valve and tends to hold the same against closing said pasjsage; means which connect said pump-chamber with said valve-casing on the side of said valve which lies away from said passage and spring, whereby the pressure in said pump-chamber acts to press said valve toward said passage and spring; a

spraying device which is connected with said pump-chamber; and means for shutting ofi' communication between said pumpchamber and said spraying device, said valve being arranged to close said passage against the tension of said spring under the influence of theincrease of pressure induced in said pump-chamber by shutting ofi said spraying device and thereby to shut ofi' the supply of liquid from said source thereof, when the spraying device is cut off.

In testimony that I claim the foregoingas my own, I have hereto afiixed my signature in the presence oftwo witnesses.
