SUBSUBFACE TILE.

Application filed September 22, 1920. Serial No. 411,954.

of Montclair, in the county of Essex and State of New Jersey, have invented certain new and useful Improvements in Sub surface Tiles, of which the following is a specification.

My invention relates to tile for sub-soil uses and more particularly to tilefor use in sewage.disposalirrigation where the tiles are placed beneath the surface of the ground for sub-surface purification purposes. I

Among the objects of my invention are, the providing of tiles that shall be economical in construction. Another object is to provide a combination of tile that shall ive a large percolative distribution area. A further object of the invention is to provide a combination of tile that shall admit of raising one tile above the surface of the lower tile. Other objects of the invention will be disclosed hereafter.

I secure these objects by means of the appliances herein described and illustrated in the accompanying drawings wherein Fig. 1 is a cross section of a sub-surface tile on the line 1-1 of Fig. 2; Fig. 2 is a section of such a tile on the line 2-2 of Fig. 1; Fig. 3 is a cross section of a tile on the line- 33 ofFig. 2; Fig. 4 is anisometric view" of the upper member of such .a tile and Fig. 5is an isometric view of the lower member of such a tile.

Referring to drawings, similar figures refer to similar parts. I (1) is an upper tile of a sub-surface 1rr1- gation tile system; (2) is a lower tile of such a system; (3) are cavities in the lower member ofsuch a system; (4) is the cavity created by super-imposition of the upper member upon the lower member; (5) are transverse ribs on the upper surface of the lower member; (6) are de ressionscreated by the transverse ribs 5); (7) are longitudinal'side beads and (8) are openings' in said side beads; (9) is an aperture left between the ends of the upper members and (10) are apertures left between the lower members.

While the accompanying drawings illustrate a practical application of my invention, it is not intended'to limit the invention to the arrangement disclosed, such disclosure beingfor the purpose ofillustration only and. not exclusive of other forms or arrangements, in which the invention may be embodied. I m

In a system of sub-soil irrigation, one of the desirable. features is to gain a large area of distribution for percolation purposes. The usual method of construction of a sub soil irrigation system is to use a tile as a lower member with a plainupper surface, upon .whichjupper surface rests either a horseshoe or similar shaped upper member. The discharge of a septic tank or siphon chamber enters the upper memher and finds outlet through the apertures between the upper members and also through the apertures between the. lower members and from thence into the soil. The distribution thereof v is practically confined to the apertures between the ends of the upper, and the apertures between the ends of the lower members.

This invention seeks to distribute so that it shall be discharged from beneath the upper member as well as into the lower.

member thus'making the discharge more uniform and preventing the clogging of (the soilv at the few points of percolation provided at the apertures-between the upper and the. lower members. Thisobject is secured by casting upon ,the lower, member small transverse ribs which are' -located between sidebeads-which are raised above the upper portion-of the lower members. In

these side beads. are apertures or weirs through which in addition to the material the feet of the upper member leaving a space through which the; liquid; can be discharged from the upper member over the side beads into'the soil. .The depression in the roof of the upper member created by the side beads. and-the transverse-ribsis filled with liquid which- .drains outthrough the weirs'or openings inthe beads; --;It is thus seen that by :the super-elevation oftheupper member,

with a space between it and the lower member, and discharge "openings' yalong the bottom of said upper member'and through the openingsin the sidebead of the lower member, abetter distribution of the liquid is secured, a;more rapidfiow results, and

the liquid flowing through the upper member from the septic tank or siphon chamber its-grammar ridges re ea fig above as that the purifying effect o'lf the, soil. is greater due" to a more uniformdistribution of the liquid, as compared with theconcen-- trated fiow when the discharge is largely confined to the apertures between the tiles.

The system illustrated is equally applicable to a filtration system in which the tile are used as collectors instead of distributors; the super-elevation of the open tile upon and above the' upper surface of theldwer tileservingto produce a more uniformly distributed and also an augmented flow;
