May 27, 1930 E-MURREY DRAINAGE SYSTEM Filed May 4, 1928v llllIlll 4v Mx A TTORNEY Patented May 27, 1930 UNITED STATES ED MURREY, OIF COLLEGE VIEW, NEBRASKA DRAINAGE SYSTEM Application led May 4,

My invention relates to drain construction, and more particularly to means for draining a depressed area such as a lagoon, swamp or portion ofland on which water stands for a period during each year, the principal object of the invention being to provide a maX- imum of drainage elements in a minimum of space for eectively draining` a large area without interfering with the tilling of the area. Further objects of the invention are to provide permanently operative drainage means, and to tra-p soil particles and prevent outflow thereof with the drained water. A

particular object of the invention is to equalize the air pressure between the atmosphere and a well receiving water from sunken drains.

In accomplishing these and other objects of the invention I have provided improved details of structure, the preferred forms of which are illustrated in the accompanying drawings, wherein:

Fig. 1 is a perspective View partly in section of a drainage construction embodying my invention.

Figg2 is a detail central vertical section of a portion of the construction including the well head and a Well cover.

Fig. 3 is a detail perspective view of the upper end of the well casing, and portions of tiling connected thereto, and the cover separated from the casing and provided with a pressure equalizing tube shown fragmentarily.

Referring in detail to the drawings:

1 designates generally a depressed area such as a low portion of a eld, and 2 the low point of the area. Receiving trenches are dug in spaced relation with the low point 2, and they are represented inthe illustrative application of the invention as comprising a single circular trench 3, the low point being the center on which the trench circle is formed. All portions of the trench may be of equal depth. Radial ditches 4- are then dug from the trench to the center 2 of the area, the floors 5 of the ditches inclining downwardly from the floor 6 of the trench 3.

A well 7 is then provided at the center of the area, extending to porous strata 8, and a 1928. Serial No. 275,089.

casing 9 is installed in the well, to receive water conducted by the ditches to the cen-` ter of the area. The upper'edge 10 of the casing projects slightly above the mouth of the well.

Drainage tile 11 are laid on the floor of the circular trench, to comprise a ring-lilre conduit to intercept and receive water thatmay run toward the center of the depressed area and water that may fall adjacent the trench.

Radial tile conduits 12 are installed in the ditches, the outer ends of the tile conduits 12 being connected into the circular conduit, and the inner ends extending in notches 13 of the casing for support from the casing, to receive water from the circular conduit and from the radial ditches and conduct it to th well. y

The upper edge 10 of the casing is free, because of the projection above the floor of the ditches and the insetting of the radial tile in the notches. Resting on the edge 10 is a cover 14 comprising a disk-like member preferably'of concrete, having a central aperture 15 to admit a tube 16, which is fixed in the cover, the lower end of the tube extending into the well and the upper end extending to a substantial distance above the surface of the surrounding land.

A porous ller 17, for example, gravel, is installed on the tile to fill the trench and ditches, for filtering soil and other solid particles frorn'the water that passes through the channels to the tile.

Drainage apparatus 'of the character described maybe provided ata selected position in relation to a depressed area, for eX- ample, at one edge thereof, for draining all or a portion of the area. The trench may be dug in circular form, the circle having a diameter appropriate to the contour of the land, for example feet; the trench may have a depth of 18 inches, and width of 18 inches. rllhe radial ditches have floors aligning with the floors of the trench at their outer ends, and incline downwardlytoward the well, the ditches being, for example, 3 feet deep at their well ends. The concrete cover shields the mouth of the well, and when the porous material deposited, the

air tube assures movement of air from the well, to prevent hindrance of flow of water into the well. The porous material retains the soil for the area by trapping the soil and checking the velocity of the water, and also prevents clogging of the tile and well by solid particles.

What I claim and desire to secure by Iletters Patent is:

l. In a drainage construction for draining a depressed area, a well atthe low point of said area, trench portions circumferentially disposed to said well to intercept water flowing toward the well, and radial channels connecting the well with said trench portions for conducting water from the trench portions to the well.

2. In a drainage construction, a circular' trench,v a diametrical ditch connected with the circular trench and having a loor declining towards the center on which the circle .is formed, and a well at said center for receiving water conducted from the circular' trench by the diametrical ditch.

.3. In a drainage construction for draining a depressed area, intersecting trenches adapted to contain a porous iiller, a well at the intersection of the trenches7 a cover for the kwell having a tube-receiving aperture, and a tube extending into the well and above the upper edges of the trenches for equalizing air pressure between the atmosphere and the well. l

4. Drainage apparatus comprising a well including a casing having notches in its upper edge, drainage tile disposed circumferentially to thewell, conduits having inner ends seated in said casing notches connecting the tile with the well, a coverron the casing, a tube extending through the cover into the casing, and a porous iller covering the cover,

tile and conduits, the tube projecting above the ller to atmosphere. u

5. In a drainage system of the character described for draining a depressed tillable area, ya circular conduit comprising drainage tile adapted to intercept water iiowing over the area, a well at the center on which the conduit is formed including a casing having its upper end located below the conduitV and having notches in its upperedge7 tile conduits connected with said circular conduit and having inner ends resting inthe notches of said casing, a cover seated on the upper end of the casing, a tube iXed in the cover and extending into the casing, and a porous filler covering said conduits for retaining soil to conserve the tillable character of the area.

6. In a draining system of the *characterl A described including a tile conduit and a well,

a casing in said well having notches adapted to receive the inner end of the conduit and to leave the upper edge of the casing free, a cover` `comprising a disk adapted to reston the upper edge of the casing, and a tube fixed in the cover having one end adapted to extend into the casing.

In testimony whereof I aliiX my signature.
