Specification of Letters Patent.

Patented Mar. 23, 19116..

Application filed SeptemberS, 1913. Serial No. 788,288.

To all whom it may concern Be it known that I, ALFRED E. WALKER, a citizen of the United States, residing in the city, county, and State of Oklahoma, have invented a certain new and useful Well, of

which the following is a specification, reference being had to the accompanying draw ing.

This invention has reference to the art of wells, and especially to water-wells, and consists in providing means for permanently and successfully harnessing or holding in check those various elements that prevent the natural and free course of incoming flow of the water into the well. For instance, to be more specific, the invention contemplates the holding back of the quick sands and other such like elements through mechanical instrumentalities which may be applied and removed at will for any purpose necessary in constructions of this character.

It is an object of the invention to provide a simple, inexpensive and practical construction, adapted for forming a well and retaining certain elements in place or under control during formation.

-In order to use the invention, any suitable construction or constructions may be adopted within the purview of the inventive .concept, so long as the undesirable elements are held in check, positively, and to this end, the sheet of drawings, accompanying and forming a part of this specification, illustrates one of the convenient forms or embodiments of said invention.

On this sheet of drawings, Figure 1, illustrates in elevation a section of the well completed. Fig. 2 is a section of a practical filtering device. Fig. 3 is an enlarged section of one of the inlet nipples. Fig. 4.- is a detail enlargement of another nipple showing means for capping the same during the construction of the well to hold back sands and other substances, and, Fig. 5 is a front elevation of one of the nipples, showing the same capping retarding bars.

In the several illustrations, similar characters of reference indicate similar parts.

After the usual digging necessary for creating an aperture for a well, and which digging is carried to the quick sand. I deposit a base, having an opening, preferably central, upon which I form a suitable casing, in any suitable manner, for instance of brick, metal or concrete, said casing being indicated by 6, the lower end whereof being formed into filtering chambers 7 and 8, preferably by bifurcatinggtbe lower end of the wall, and introducing into said bifurcation a wall 9, that rising from the bottom nearly to the top 10 of the bifurcation forms two communicating chambers, adapted to contain an elongated body of filtrant through which the incoming water may percolate. As digging proceeds, this structure, together with the upper casing wall 6 is adapted to gravitate with the base 11, until the latter is deposited upon bed rock, and during the descent, additional wall may be created upon the wall 6 to finally finish the casing. lVhen the base reaches bed rock,

the opening (not shown) is closed, or sealed. The annulus formed by the bifurcated filtering chamber is filled with suitable filtering material lying on either side of said wall 9.

In the outer wall 12, of the filtering cham-' .ber of rods 15, preferably such as will not corrode, and these are designed to prevent the filtrant in the chamber from escaping. In the inner wall 16, of the filtering chamber, there may be located a suitable number of nipples 17 that are provided with reducing nipples 18 that ar externally screwthreaded as at 19, to receive caps 20, while well construction is in process, and when the well is finished, and the hole in the base sealed against incoming of the sands, then these caps may be removed, and in their stead may be applied any suitable sort of filtering devices, such, for instance, as is shown, and which comprise a chamber, preferably in the form of a globe 21 having an interiorly screw threaded nipple 22 to take over the nipple 18. This filtering device is also provided with an outlet nipple 23 through the body-of which are passed rods 2-l. and, if desired, rods 25 may be passed through the body of the nipple 22 for holding the filtrate in the filter, although these need not be used except at will.

In building the well, after digging, the casing is dropped together with the filtering chamber and the foundation built therewith into the opening. As the sands are removed through the opening of the foundation the structure gradually descends, giving opportunity to build onto the casing above. Then the foundation finally strikes bed rock, and the opening is cemented r jtheru'ise closed to prevent the incoming of 1 sands, when the caps 20 are removed, the

filters applied and the water may then surge into the well. I

llanng thus described this inventlon, I claim:

1. A casing, a filtering chamber having a dividing wall, filtering material in the chambers of the filtering chamber, an inlet, having access to one chamber, and outlet from another and into the casing, retaining bars associated with the inlets and outlets, and filtering devices in association With the outlets.

A casing, an annular filtering chamthe chamber, said inlet and outlet being on opposite sides of the filtering material, and

filtering devices in association with the outlets.

Signed at Oklahoma City, in the county of Oklahoma, and State of Oklahoma, this 2nd day of September, in the year 1913.
