UNITED STATES ALBERT E. HARRIS, OF LOS ANGELES, CALIFORNIA.

{ 1 VALVE.

Application filed' October 19, 1927.

' By way of explanation, it might be stated that it is a known fact that irrigating systems in common use are faulty because of the absence of means to insure a uniform distribut-ion of the water.

The well known canal irrigating system, owing to the difierence in the contour of the ground results in greater water pressure at certain points than at others, and while the overhead irrigation system has proven the most eflicient, it has been found that various degrees of water pressure exist at different points on the pipe line, owing to the fact that the pipes run through high and low land, to the end that it is impossible to insure a uniform pressure resulting in irregular precipitation. 7

It is therefore the object of the present invention to provide a novel form of valve esspecially designed for use in irrigating systems wherein pipe lines are used, the primary object of the invention being to provide means for regulating the flow of water to the precipitators or an irrigating system, insuring uniform precipitation at all times.

Another important object of the invention is to provide a valve of this type which may be readily and easily secured to the riser pipe or pipes of an irrigating system, which pipes conduct the water to the precipitators for distribution.

A still further object of the invention is to so construct the valve that the water pressure will be equal both downward and upward and the pressure will be determined by the amount of water permitted to pass into the valve.

Another object of the invention is the provision of a valve which will permit of a water pressure gauge being inserted therein so that a person may determine with a degree of accuracy, the water pressure at a particular point.

WVith the foregoing and other objects in view which will appear as the description proceeds, the invention resides in the combination 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, may be made within the scope of what is claimed, without departing from the spirit of the invention.

Referring to the drawing:

Figure 1 is an elevational view showing Serial No. 227,288.

a valve constructed in accordance with the present invention as positioned on a riser pipe and supporting a precipitator.

Figure 2 is an enlarged vertical sectional view through thevalve.

Referring to the drawing in detail, the reference character 5 designates the main pipe line of an irrigating system of the overhead type, to which the riser pipe 6 is connected and communicates with the interior of the pipe, it being understood that these riser pipes are arranged along the main pipe of an irrigating system, predetermined distances apart.

The valve includes a body portion 7 formed with a lateral downwardly extended portion 8, communicating with the body portion through the opening 9 which is disposed intermediate the ends of the body portion so that when water enters the body portion, the pressure of the water against the plug 16 will cause the pipe to be held in position at all times.

The latera ly extended portion 8 is internally threaded to receive the threaded end of the riser pipe to which the device is secured so that water from the main pipe line may be directed into the body portion through the riser pipe 6.

Supported within the body portion is the valve 10 which is in the form of a barrel, the same being provided with grooves to receive the packing rings 11 which insure a fluid-tight connection between the valve proper and body to which the valve is positioned or supported.

Formed integral with the barrel 10 is an enlargement- 12 that defines ashoulder at its lower end providing a rest for the barrel 10, it being understood that the barrel 1O supports the weight of the precipitator pipe 13 which is connected therewith through the union 14,

An opening indicated at 15 is formed in the barrel l0 and is designed to move to a position opposite the opening 9 to regulate the passage of water through the valve proper, it being understood that the water pressure passing through the valve may be regulated by movin the valve to cause a greater or less area of the opening to be brought before the opening 9.

The lower end of the barrel 10 is normally closed by means of the plug 16 which plug however, may be removed so that a suitable water gauge may be inserted in the barrel 10 to determine the water pressure passing through the valve. It will thus be seen that r with a water gauge positioned in the barrel 10, the barrel 10 may be rotated until a predetermined pressure is registered on the gauge, whereupon the gauge may beremoved and the plug 16 positioned to close the end of the barrel. 7 v

It may be necessary to make adjustments of the valves throughout the length of the main pipe line becauseof irregularities in the groundsurface, which as before stated, cause uneven pressuresat the precipitators.

After the adjustments along the main line of an irrigating system have been made, the

valves will be marked, to the end that it will not be necessary to make further adjustments or tests of; the water pressure to lnsure even precipitation.

The reference character 17 indicates a preeipitator which may be of any desired construction. r V

I claim: V

A valve for irrigating systems including a vertical body portion, a lateral downwardly extended portion adapted to be secured to a riser pipe of an irrigating system, a barrel having a shoulder at its upper end resting 011 the upper end of the body portion the lower end of the barrel lying flush with the lower end of the body portion, a removable plug in the lower end of the barrel to close the lower end of the barrel, said barrel having an opening adapted to register with the downwardly extended portion to control the passage of water throughthe barrel. 7

In testimony that I claim the foregoing as my own, I have hereto affixed my si nature.
