To all whom p'fi may concern:

Be .it known that l, FRANK L. Umoin'of Boston, in the conntyofsnfiolk and State of Massachusetts, have invented certain new'and useful improvements in 'Gesspools, of which the following is e specificeeion-L it is the object of my invention to-provide such improvements in cesspools as will re suit in the complete separation of the solid end semi solid portions of the sewage from the water or purely fluid portions, so that the latter may be taken up or absorbed by the earth and the former may-be kept from opersting to prevent such absorption by the earth of the letter,

A dimcnlty arising in the use of cesspools es heretofore constructed has been that the vseini-snlids of the sewage-matter, particularly greiise and greasy matter, have been allowed to so flow into the reservoir or pool from which it vwere designed the water should be absorbed by-the earth The efiect of this has been to in eshort time so cost the wells of said reservoir or. pool and close the pores or passages in the earth as to prevent absorption of the water. 'By my invention this diiiicult'y is entirely overcome, the construction of my improved cesspool being such as to effectively separate the solids and semi-solids of the sew- 7 age matter from the water or purely liquid In cerryingont my invention ll construct a,

receiving and separating pool a; of suitable;

form and dimensions and s coininnnicoting discherge pool h, usually, though noi always, larger then the pool a, In the' pool a, across 0 the some and extending up to epoint sneer inidwey between the top and some of the l in mosiz'insmnces constrnctswsten the partition 0. This arrangement of the suplin-e (horizontally considered) upon which the Of the drawings, Figure 1 is a vertical sec tightpsrt-ition or wall 0, dividing the said pool a into'two compartments d e. The sew age end water flows intopool a through the pipe f, which pipe enters the said pool a at a, high point and turns downward to a point which brings its month below on imaginary horizontal line passing just over the top of 6o ply-pipe f is preferred by me, though it is not essential, since it can be'variously arranged without departing from the nature-or spirit of the invention.

g designates the pipe afiording means of communication between the pools a and b.

' The said pipe 9 extends from a point in the compartment e considerably bclowthetop of the partition 0 up toa. point just below the pipe f enters the pool a, at which point the said pipe 9 turns and possesv through to and into the pool 11, the sides or walls of which are constructed of loose stone, as shown, or otherwise formed so as to permit the Water in 7 5 the said pool to soak-0r filter therefrom into the ground.

' Pool a, is provided with s men-hole Mend pool 12 may be constructed-in like manner.

In the use of my improved cesspool the watercarried sewage will flow into the pool 0; through 'the'pipe f, the solids andell metterof greater specific gravity than the water settling to the bottom of thecompertment d, while the clear water will rise and flow over the pertition c into'the compartment e, fromwhence it will be taken by the pipe g and conveyed tothe pool 11. The oil and grease in the sewage, which oper ates to cost or line the wnlls'of cesspools, so as to, prevent the water in. the said pools from being absorbed byor soaking. into the earth, rises to the surface in the pool 0;, and is kept entirely from flowing into pool 12 by resson of the feet that the waiter flowing into the pool b entersthecommnniceting pipe 9" eta point 5 greatly below the surface of the water in the compartment e end-below the top of the pan tition cl In this way nothing but compares .tively clear weterwill: be delivered in pool b,

which clear water will resdily'sosk into or be absorbed from said pool by the eerth. Pool a, being designed as a, means for separating theseiids and semi-solids fromihe water, is made water-tight; The said. solid matter, or

matter of heavier specific gravity, will be collected in the compartment d, from which compartment it may be removed from time to time, es the necessities of the case may demand." The greasy-matter and matter-offices specific gravity than the water can also be readily skimmed off from the top of the water in the pool a and removed through the manhole opening thereinto.

Heving time described my inventio n, I deciere that what I claim is- The improvement in cesspoois consisting of e "water-tight reservoir provided "with a, water-tight partition 0-, a, receiving-pipe extending into said rwervoir and extending downward therein to a point below the surface of the water, a reservoir heving'eides through which the water may percoiete, and

a pipe extending from a point below the surfec'e'of the water in the water-tight reservoir up tov a, pointbeiow that at which the receiv- August, A. D. 1889. FRANK L. UNION.
