PUMPING SYSTEM. I

Specification of Letters Patent.

Application filed January .23, 1911. Serial No. 604,103.

To all whom it may concern:

Be it known that I, ELIJAH H. PERKINS, citizen of the United States, residing at Dinuba, in the county of Tulare and State of California, have invented new and useful Improvements in Pumping Systems, of which the following is a specification.

This invention relates to a pumping system.

It is the object of this invention to provide a means for removing water or other with a single pump which is simplein construction and operation, and which is economical in installation and upkeep.

In irrigating operations where the water provided from sunken wells, especially arid regions, the volume of water re quired is greater than'can be supplied from a single well. owing to slow percolation of the water into the well which makes it neoshown in the essary to drive a number of wells in order to obtain water in a sufficient quantity. Heretofore, separate pumps have been em ployed for each well, or a single pump has been directly connected ing to a number of wells, both systems be ing objectionable in many respeets, 'particularly in the expense of first cost and repairs.

It is the object of this invention to supplant these systems by the use of the principle of the siphon which I haveadapted and arranged to meetthe requirements of the use to whichit isto be put.

The invention consists of the parts and the combination and construction of parts as hereinafter more fully described and claimed, having reference to the accompanying drawing, in elevation partly in section, illustrating the construction and operation of the invention.

In the application of this invention, as drawing, a number or series of wells AB,,C are driven at suitable distances apart, one of the wells, as A, being employed as a main well and the remainder of the wells B- C being auxiliary thereto. There may be any desired number of auxiliary wells, the two shown in the drawings being sufiicient 'for illustration.

My present invention resides in connect,-

d'ing th uxiliary wells BC to the main well A'by "means of a siphon here shown as constructed of verticallyxdisposed pipes, 2-3

4, connected together their upper ends by means of a horizontal pipe 5. The pipes (ibeneath the valve to a pipe line leadin which the figure is'a View low the water level therein and below the.

water level in the wells BO. The casing 6 is connected to a pump 7 of any suitable description by means of a-pipe 8, and is adapt-- ed to be opened to the well A through a foot valve 9 mounted in its lower end, a pipe 10 leading downward from the casing in the well A.

The pipe 5 is connected to a pump 11 through a pipe 12, this pump 11 being provided for the purpose of drawing off the air in the pipes 2345, which, by creating Patented J nine 6, 1911.

9 to any suitable depth 3-4 extend into the wells B-C, some disa suction, causes the water in the wells to rise and fill the pipes, so that the siphon will operate, as later described. A cut ofi' valve 13 is disposed in the pipe 12 which is closed when the pump 11 has drawn water, so that air will not be break-the siphon.

In operation the pump 7 is set in motion so as to draw water from the chamber in the casing 6, this chamber being normally filled by reason of the water in the well A rising in the pipe 10 and entering the casing through the foot valve 9; the water rising in the pipes 8,2 to its level in the well A. As the water is drawn from the casing 6 by the pump 7, a suction is created therein which causes a flow of water from the wells BC through the siphon,- and also draws .from the Well A through thefoot valve 9. -From this it will be level in wells seen that as the water the Well A falls below that of the BC that water from the latter will 'flow through the siphon to the former until a common level is reached. In this manner a supply, of water equal the capacity of the number of the auxiliary wells BC will be delivered to the well A, While the power consumed by the pump 7 will be no more than that required for handling the same volume of w ter'from a single well, the friction of raising water from the wells B. C being overcome bythe siphon.

Cut-off valves 14-15 may be disposed/ in the pipes 34 in any suitable. manner, so that the siphon" may be caused to act on either well B or C, separately and inde pendently of-the other.

rod

It is obvious that the greater the distance pumping the lower terminal of the pipe, well A is disposed below the auxiliary wells BC the greater will be the elliciency of the siphon. Inasmuch as the fall of water in the pipe 2 is caused to a certain extent by the suction created in the casing 6, and the "greater the length of the fall of water in the pipe 2 the greater the siphoning action on the pipes 3-4, it follows that the lower the casing 6 is disposed below the water level in the well 13-0, the better the results obtained.

Having thus described my invention what I claim and desire to secure by Letters Patent is- 1. A pumping system, comprising a main well, a number of auxiliary wells, means for siphoning water from the auxiliary wells to the main well, said means consisting of vertically disposed pipes in each of said wells, a horizontally disposed pipe connecting the upper ends of said vertical pipes, pumping means for drawing a1r from the siphon through a pipe connected witlrsaid horizontally'disposed pipe, a casing disposed in the main well on the lower end of-the siphon,

means connected to said casing,

2, in the and a toot valve in said casing opening to the water level in the main well.

2. A pumping system, comprising a mam well, a number of auxiliary wells, means for siphoning water from the auxiliary wells to the main well, said means consisting of vertically disposed pipes in each of said wells,

a horizontally disposed pipe connecting the upper ends of said vertical pipes, pumping means for drawing air from the siphon through a pipe connected with said horizontally disposed pipe, a casing disposed in the main well on the lower end of the siphon pumpin means connected to said casing, a

foot Va ve in saidcasing opening to the main well, and cut-ofi valves arranged in the siphon to cut ofi iliary wells. I

In testimony whereof I have hereunto set my hand in the presence of two subscribing witnesses.
