AUTOMATIC WATER-DISTRIBUTION CONTROL.
Application filed April 6, 1926. Serial No. 100,122.
My present invention has to do with the automatic distribution or control of water supplied by a ump or from any other source of supply; an itcontemplates the provision of automatic control means possessed of the practical advantages hereinafter ascribed to the same.
With the foregoing in mind, the invention in all otf its details will be fully understood from the following description and claims when the same are read in connection with the drawing, accompanying and forming part of thisspecification, in which The figure is a view partly in elevation and partly in vertical section illustrating the automatic control means constituting the preferred embodiment of my .invention.
y improvement com arises a conduit- 1 adapted to be connected with a pump or with any appropriate source of water supply; and it also comprises a conduit 2 designed to be connected with a pneumatic pressure tank, not shown, said tank being designed for the supply of water to a dwelling house or the like. At 3 is a conduit designed to lead excess water to a stock watering tank or to any other desired point of discharge. Inthe illustrated embodiment the conduit 3 carries a bracket 4:, and on the 30 said bracket 4 is a piston cylinder 5 having seats 6 and 7 spaced one above the other and also having a cap 8 at its upper end. The pipe 2 is connected by a pipe arm 9 with the lower end of the piston cylinder 5, and in the conduit 2 and at a point between the pipe arm 9 and the pipe or conduit 1 is arranged a check or non-return valve 10 arranged to open toward the right in the figure constituting the drawing. A cut oil valve 1 I is arranged in the pipe 3 and its turnablo body orplug is provided with a crank 12 connected through a rod 13 with one arm of a lever 14 that is pivoted at 15 on the bracket 4, and is provided on its opposite arm with an adjustable weight or pea 16, the adjustable positioning of the pea or weight 16 on the lever arm being preferably attained by the threading of the pea or weight on the arm as shown at the right of the drawing. An appropriately packed piston 17 is dis posed and movable in the cylinder 5 between the seats 6 and 7 therein, and when the said piston 17 is disposed on the seat 6 it will be noticed that only a portion of the area of the piston will e exposed to the pressure in the conduit 2 in connection with the bethe weighted arm of the lever 14 through the mcdrum of a rod 20. y y
In the practical operation of my improvement it will be understood that when the pneumatic tank alluded to is empty or is lled with air at atmospheric pressure, the piston 17 will rest on the seat 6, and the valve 11 will be closed. With the parts positioned as stated, the water from the pump is forced pastthe check valve 10 andthrough the conduit 2 to the pneumatic pressure tank. This operation continues until the ressure in the pneumatic tank becomes suhciently high when the pressure acting against the piston 17 will raise the piston 17 to the seat 7 and will thereby rock the lever 14: and open the valve 11 whereupon the water will flow past the valve 11 to a stock watering tank or any other desired point of discharge or point at which it is desired to impound the water. The pressure against the underside of the piston 17 is always the same as the pressure present in the pneumatic tank, and when sufficient water is removed from the pneumatic tank the weighted lever 14 operates to move the piston 17 downwardly to the seat 6. The said movement of the lever 14 under the action of its weight 16 also operates to close the valve 11 with the result that water will again be supplied to the pressure tank.
Manifestlv the pressure in the pressure tank alluded to may be readily regulated by changing the position of the pea or weight 16 on the lever 14.
It will be apparent from the foregoing that when the pistonv 17 is disposed on the seat 6, the area of the piston 17 that is subject to the pressure in the pneumatic tank is reduced to the extent of the area of the seat- 6. By virtue of" this. inert-used pressure is applied against the piston 17 after it leaves the seat 6. and consequently the piston 17 will be moved quickly to the seat 7 and will remain against the said seat 7 until the pressure in the tank has been reduced to the extent of several pounds.
It will be appreciated from the foregoing that my novel control means is extremely simple and inexpensive in construction, and is susceptible of ready installation. and in practice may he depended upon to operate in a reliable manner and this with but little or no attention.
I have specifically describedthe construction and relative arrangement of the parts embraced in the present and preferred enibodirnent of my invention in order to impart an exact understanding of the said embodiment. I do not desire, however, to be understood as limiting myself to the construction and arrangement as illustrated and described, my invention being defined by my appendedclaim Within the scope of which modifications'may be made without departure from my invention. For instance the cap or partial closure 8 may be of any approved type that will permitv the circulation of air between the chamber portion above the piston 17 and the atmosphere.
Having described my invention, What I claim and desire to secure by Letters Patent, 1s:
Automatic Water distribution control means comprising a pipe adapted to be connected With means for supplying Water under. pressure, a turnable cut out valve in said pipe and having a crank, a pipe connected with the first named pipe at a point between the source olf supply and the cut ell valve, a. non-return valve in said second named pipe and arranged to open in a. direction away from the first named pipe, a. bracket on and extending laterally from the first named pipe, a piston cylinder carried by said bracket and disposed at right angles thereto and connected at one end to a pipe in connection with the second named pipe at the opposite side of the non-return valve. with reference to the first nanied pipe. the second named pipe being adapted to lead water under pressure to a pressure ta k, a piston in said piston cylinder and having); a rod extending through the oppmite end thereof, a lever pivotally connected at an intermediate point in its length to the said bracket and arranged alongside the same. a rod connecting one arm of said lever and the crank of the turnable cut off valve. :1 rod connecting the other arm of said lever and the piston rod, and a Weight aiiljustable on the last named arm of the lever in the direc' tion of the length of the lever.
Tn testimony whereof I atlix my signature.
