-D. P. HOWELL. SYSTEM FOR COLLECTING WATER. APPLICATION FILED FEB. 17, 1920.
UNITED STATES DAVIS P. HOWELL, OF MODESTO, CALIFORNIA.
SYSTEM FOR COLLECTING WATER.
Application led February 17, 1920.
To all whom t may concern Be it known that I, Davis P. HOWELL, a citizen of the United States of America, and resident of Modesto, in the county of Stanislaus and State of California, have invented certain new and useful Improvements in Systems for Collecting lVater, of which the following is a specification.
This invention relates to well production and particularly to means for increasing the capacity of wells and for increasing the supply of water compared with that which would ordinarily collect at the bottom of a well where casings or well linings are employed in the hole.
A still further object of this invention is to provide a device of this character which will not interfere with the pumping operation and in which the means for collecting the water or fluid at the bottom of the shaft or well is supplemental to that of the pump.
With the foregoing and other objects in view, the invention consists in the details and in the arrangement of the collecting device with relation to the pump shaft, and in describing the invention in detail, reference will be had to the accompanying drawing in which I have illustrated by sectional view, the apparatus and method employed for carrying the invention into practice.
- In these drawings I have shown conventionally, the formation through which the well shaft or casing extends as having alternate layers 5 of relatively hard strata with interposed layers G of water bearing sand or other light disintegrated material, and 7 denotes the well shaft or hole having a casing or lining 8 and this casing is supposed to be supplied with a water elevating mechanism of any appropriate type. As, however, the mechanism for raising or pumping the water has nothing to do with the present invention, it will not be described in detail. In juxtaposition to the first mentioned shaft or boring, another `shaft or hole 9 is Specification of Letters Patent.

produced having a casing l0 therein, and obviously, it is desirable that the second mentioned shaft shall be equal in depth to that of the rst mentioned so that any deposits of water in the second mentioned shaft may reach the pool, water course or cavity from which the first mentioned shaft is supplied.
In order to collect as much as possible of the water which may be contained in the strata through which the second mentioned shaft is sunlr, the depth of each water bearing stratum from the surface is determined during the drilling operation, and at each said stratum, the casing l0 is provided with one or more perforations in order that the water may escape from the higher levels and 'descend through the casing to the bottom of the shaft 9 where it will find its way to the shaft 7 to augment the body of water which may be pumped through the shaft 7.
I do not wish to be limited with respect to the location of the perforations with relation to any certain stratum nor to the type of casing employed, as the invention has to do more particularly with the simple and comparatively inexpensive means for causing the water of the higher levels to descend to the point where it can be removed in the manner stated.
lVhile I have referred to the well as being designed for the purpose of collecting` and pumping water, it is to be understood that the same principle can be employed in connection with the recovery of oil and like deposits.
In a system for collecting water, a well through which the water is raised, and a well shaft adjacent thereto extending to the level of the first mentioned well, a casing in the second mentioned shaft having openings at different levels where water bearing strata occur.
