4 Application led March 30, 1915, Serial'No. 18,104. Renewed April 27, 1916. Serial No. 94,046.

To all whom t may concern Be it known that I, EDWIN O. LAWRENCE, a citizen of the United States, residing at Port Jederson, in the county of Sudolk, State of New York, have invented certain new and useful Improvements in Cesspools; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

This invention 'relates to cess-pools, and has for its object the provision of a cesspool so constructed that it cannot be clogged bythe accumulation of the solid matter Aforming a part of sewage flowing thereinto,

and provided With means'whereby the water is carried off rapidly and dissipated into the surrounding soil. A11 important object is the provision of a cess-pool provided with drain orifices in its sides, whereby water may -flow out easily while the entry of sand or the like is prevented.

Another object is the provision of la cesspool so constructed that the overflow of t water will be drawn from the center of the dev-ice thereby preventing clogging of the piping .by either the solids which settle to the bottom of the device or by the grease 1 which accumulates and floats on top of the water.

A further object is the provision of a cesspool of this character which will be simple and inexpensive in manufacture and installation, durable and efficient in service, positive in action, sanitary and not offensive and a general improvement of the art.

With these andother objects and advan-i tages in view, the invention consists in the novel construction and arrangement of parts to be hereinafter more fully described and claimed, and illustrated in the accompanying drawing, in which,

Figure 1 is an elevation of my device embedded in the ground and shown associated with the sink pipe and ventilator pipe of a house, Fig. 2 is a vertical sectional view therethrough, and Fig. 3 is a horizontal section taken along the line of the overflow pipes.

Referring more particularly to the drawing, the numeral 5 designates the main or cylindrical portion of my cess-pool which is formed of a plurality of cement bloc-ks 6 trapezoidal in top plan and having inwardly p converging sides whereby ya plurality of the blocks fitting snugly together will form a' l circle. Each block is provided witha plurality of vertically extending holes 7 ad- ]acent its 'inner face and is further provided With a plurality of/downwardly and outwardly extending holes 8 communicating portion or closure for the cess-pool is formed as an arch 9 formed of any suitablebrick.

A pipe 10 extends from the waste pipe of 1 the sink or other place to be drained and extends into the cess-pool at the skewback 11 or the junction of the arch 9 with the `cylindrical portion 5, the pipe 10 being provided with a trap 12 for preventing the passage of gases or odors back up through the waste pipe of the sink.

In order to carry ofi" the water flowing into the device through the pipe 10, I provide a pipe 13 extending within the' device, passing through the bottom and extending down into either a layer or stratum of sand or gravel. The pipe 13 is provided with a point 14 for facilitating its penetration of the ground and is also provided with a plurality of holes 15 for the outlet of Water. "v

A T-coupling 16 is connected in the pipe 13 and has connected thereto a length'of pipe 17 extending into 'the lateral arm of a T- coupling 18 which has its upper opening closed by a plug 19 and its lower,- portion connected with a pipe 20 extending downwardly to substantially the center volf' the cylindrical portion 5. The pipe 13 has connected therein a double T-coupling 21 to the upper portion of which is connected a pipe 22 which carries a T-coupling 23 connected with an elbow 24 which has connected therewith a pipe 25 .leading to the ventilation pipe commonly provided on a house. The lateral portion 26 of the coupling 23 is open to the air within the cesspool.

portions of the double T-coupling 21 and Pipes 27 are connected with the lateralv pipe 20 and into the pipe 17 and from Athere ing throughl the ground.

into the pipe 13. When the level of the waste reaches the pipe 17, water will run out through the pipe v17 into the pipe 13 -.and into4 the layer of sand, gravel or water into which the pipe 13 extends, thevwaste running out through theholes 15 and seep- If the waste runs into the device more rapidly than it can be taken care of by the pipes 20 and 17,

and if the pipe 13'should become Vlled on account of saturation of the layer of sand'or gravel atthe end of the-pipe 13, the waste will rise past the -pipe 17 and to the -pipes 27. When .this happens the water passing through the pipe 17 will rise in 'the pipe13 and pass through'the -pipes 27 into the an nular passage 28 fromv whence it will flow .downwardly 'through the vertical -,passages formed by the alined holes 7 and through the holes 8, eventually v seeping into and through the soil surrounding the device.

The solid matter will not accumulate for any great length of time withinlvthe device, for the reason that it will decompose and be carried olf with the water. The gases formed by decomposition .will passthrough the coupling 26 and out through the pipe 25 'which leads to the yent pipe extendingabove the roofof a house.

From the foregoing description and a study of the drawing it will be apparent that I have thus provided a` simple, noveland ecient cess-pool from which the. waste 'will be drained quickly and eiiciently into the surrounding soil and in which possibility of clogging is prevented and lconsequently the necessity for cleaning is eliminated.

lt will. be readily understood that ll reserve the right to make various changes in the form construction and arrangement of parts without departing from the spirit of the invention or limiting the scope of the Vtions, a pipe connected with said pipe and extending downward adjacent the center of the receptacle, and a pair ofjoveriiow pipes connected with said irst named pipe and extending into said annular passage, said rst named pipe being further connected at its upper end with said vent pipe.

' l2. `A cess-pool comprising a receptacle lhavingits peripheral wall provided with a plurality of vertically extending passages. having inclined passages communicating' therewith and extending tothe outside of said receptacle, an inletpipe connected withsaid receptacle and discharging thereinto, said inlet pipe being connected with a waste pipe, a pipe within said receptacle, passing through the bottom thereof and extending into a layer of sand, an outletv pipe connected with said second named -pipe and terminating at substantially the middle of the receptacle, a pair of overiow .pipes connected 'with said secondnamed pipe above the point Vof connection of vsaidthird named pipeI and extending into an annular passage in the Wall of said receptacle communicating with said vertical passages, said second named pipe being provided with an air inlet above said last named pipe, and a pipe connected with said second named pipe and communicating with the atmosphere.
