DRAINAGE SYSTEM.

ASpecification of Letters Patent.

Patented Feb. 7, 1922.

To all whom it may concern Be it known that I, WILSON J AMES SNIvELY,

a citizen of the United States, and a resident of Mount Pleasant Township, in the county of Westmoreland and State of Pennsylvania, have invented certain new and useful Improvements in Drainage Systems, of which the following is a specification.

This invention relates to an improved drainage system and apparatus, and more particularly to an improved method or system of drainin whereby sulphur water and all other objectionable waters that flow from coal mines into the creeks and streams can be drained or gotten rid of, and swamps and marshes drained so as to dry up swampy and marshy land to permit use thereof for agricultural purposes or otherwise, means beingprovided to collect the sediment so as to prevent clogging up of the system in order that its indefinite use may be insured.

The present invention is also designed to effectively displace the use of ditches or trenches in lowlands where such method of draining is ineiicient and in most instances too expensive and impractical, owing to the inefficient drain and the constant filling thereof with sand carried in the stream of 'water and due to the relatively impervious character of the upper soil. In the present invention, use is made of a hole or Well drilled into the ground at a depth required to reach a water level, and preferably a plurality, particularly the third water level, at which depth, a lower water stratum or porous earth is reached in which there is created a suction, such water or air level resulting from a subterranean flow or stream. In this way, the objects of the invention above specified, can be effectively accomplished. f l

With the foregoing and other objects in view, my inventionA resides in the combination and arrangement of parts, reference had to the accompanying drawings, in w ich:

Figure 1 is a sectional .view illustrating the application of the invention, and

Figure 2 is a horizontal sectional view of thepsedimentation or detritus chamber.

Referring to the drawings in detail, in which like reference characters designate 4corresponding parts throughout the severalviews, and in the carrying out of the invention, there is placed at or above thesurface 10 of the ground a sedimentation or detritus chamber 11 illustrated as formed of cement or the like, of rectangular or other cross secthird baflie wall 16 extending to the top 13' and hel ing to support or sustain the same,

except or an openlng or weir 17 cut throu h f the same near the top, in order that t e water may drain from one side to the other.

The chamber is designed to receive the drain Water through an opening or pipe 18 lpadin through an opening 19 into one side wall o e the chamber, so as to drain the sulphur and other objectionablawater from mines, or water from swamps, marshes or other places or low ground which isnot properly drained. In the case of a mine, the pipe leads from the bottom of the mine pit or shaft, forming a mine outfall at one side from which the drain is inclined-to the chamber as already described.

After the Water passes through the weir 17, it is discharged into an outlet or drain pipe 20 engaged through an opening 21 in the bottom of a chamber beyond the baille walls at the end remote from the inlet. It

will also be noted that the drain pipe orv opening and the inlet are at a higher level than the outlet end 22 of the pipe 20 owing to the overflow over the opening or weir 17 being on a level with the inlet 19. Water being led into the detritus or sedimentationt sus off all surface water or water above the third water level. At this water or air level, where there is a subterranean flow or steam, a suction is created so as to effectively draw or take up the water flowing into the chamber and overflowing into the outlet pipe or casing 20. As shown in the drawings, the pipe is driven through the first Water level 23 and through the second water level 24, being also cased off from the same so as to prevent injurious action upon the water drawn for drinking purposes. These water levels are also air levels. However, the water is discharged `into the third water level, the sediment being caught in the chamber 11 which owing to the removabillty of the top thereof, can be readily and economically cleaned without permitting the foreign matter or sediment to clog up the drain system. Thus, all water in the chamber above the stand pipe or outlet aththe upper end of the latter is discharged mto the third Water level 25, the well being I drilledto the lowest point While placing the chamber at or slightly below the surface so that the water surrounding this point is drawn into and down this well. No evil effects can be caused by this method, the

earth forming a natural filter and permitting mine shafts or pits, as well as swamps and marshes or low ground to be effectively drained, and particularly getting rid of and avoiding sulphur and other objectionable water in mines flowing into the creeks and streams. Thus, any water drawn from a higher level for drinking purposes will have been thoroughly filtered and cleansed so that impurities will have been removed therefrom. It is of course to be understood that the chamber does not serve the purpose of a filter nor do 'the pipe or casing 20, the water being carried directlyvinto the subterranean strata or third water level without circulating through the ground and around the chamber or receptacle or through porous pipes or the like, and especially carried below the first water level. The casing mu|st be impervious and in practice, all surface wafer is cased off around the first and second water levels and throughout the depth down to the point at which the solid formations are reached for the discharge, thus making the casing doubly secure and permanent against water the same. In practice, a grouting of cement 26 around the outside of the iron casing, in the event of the iron casing rusting away, is used, the cement remaining intact and forming the necessary casing to prevent water filtering therethrough into the finst or second water levels. In this manner, water is taken into the hole or well at a very rapid rate and the particles of coal or other matter that ma be in the water, fiowing from the mines and percolating intoother places, will find a lodging place in the sedimentation chamber and can be easily removed from the same. In fact, if necessary, the chamber may be protected from-cold, etc., by building a small house or other arrangement for its protection, thus permitting the device for use in 'reclaiming swamps, bog

lands, not by filtration, but by drawing al water down the holes and carrying it away so far below the surface that the earth forms a natural filter and water drawn from the earth at a higher level will be thoroughly cleansed and purified. In this manner, swampy and boggy lands may be used for agricultural purposes and roads incidental to the use thereof. v

In view of the foregoing, it is thought that the operation of the device will be readily understood, and in view of the simplicity and practical value that it will commend itself to those-skilled in the art.

Having thus described my invention, what claim is: 1. `A method of draining water from surface pools,mine shafts,marshes and swamps or the like, and of preventin pollution of the upper water strata consisting in drilling a hole through the soil to a lower water stratum and porous earth to create a suction, and casing off all surface and other water above said stratum.

2. A method of draining water from surface pools,mine shafts,marshes and swamps or the like, and of preventing pollution of the upper water strata, consisting in drilling a hole through the soil to a lower water stratum and porous earth to create a suction, casin off` all surface and pther water above sai stratum, passing said water through a sediment cha-mber and discharging the overfiow from 'said chamber into said hole.

3. A method of draining water from the surface of land consisting in drilling into the earth through a plurality of water levels to an air level forl creating a suction and discharging the water thereinto.

4. A method of draining above the surface and preventing pollution of the upper water strata consisting in arranging a sedimentation chamber at the surface, passing the surface or other water through said chamber, arranging the chamber to discharge the overflow therefrom while retainin the sediment, drilling a hole into the eart to the solid formation forming the third `water level and air level to produce suction, casin off all surface and other water above sald third water level and air level, and leading the overflow into said hole.

5. A method of draining water from the surface of land and of preventing pollution y of the upper water strata consisting in drilling into the earth through a plurality of sof latv

water levels to an air level for creating a said hole and discharging the Water therein, suction, and casing said hole and dischargthe sediment in the Water being collected ing the Water thereinto; on its Way to discharge whereby to prevent 10 6. A method of draining Water from the the same from emptying into the subtersurface of land consisting in drilling into the ranean strata and coagulating to clog up the earth through a plurality of Water levels to Same. an air level for creating a suction, encasing WILSON JAMES SNIVELY.
