MATTHEW MORIARTY, OF BANGOR, MAINE.

CESSPOOL.

SPECIFICATION forming part of Letters Patent No. 498,287, dated May 30, 1893.

Application filed August 26, 1892.

T0 at whom it may concern.-

Be it known that I, MATTHEW MORIARTY, a citizen of the United States, residing at Bangor, in the county of Penobscot and State of Maine, have invented new and useful Improvements in Oesspools; and I do hereby declare that the following is a full, clear, and exact description of my invention, which will enable others skilled in the art to which it appertains to make and use the same.

My invention relates to new and useful improvements in cesspools and consists of an outlet or overflow connection so constructed and arranged as to form a cleanout-opening whereby the contents of the cesspool can be pumped or bailed directly into the drain en tering into the main-sewer; and it also forms a trapped outlet to prevent gases generated in the sewer from entering the cesspool (thereby making the water foul) and from there ex-. tending into the street.

The object of my device is to provide suitable andconvenient means for cleaning out a cesspool within the same and obviate the necessity of bailing the foul water into carts and hauling the same through the streets as has been the usual method. This object is accomplished in the following manner by the aid of my invention throughout the description of which reference is made to the accompanying drawings forming part of this specifica tion, in which- Figure 1 represents a sectional elevation of a cesspool and its adjoining drain provided with my improved outlet. Fig. 2 is a perspective view of the case of my improved cesspool-outlet with its covers and valve removed to show construction. Fig. 3 shows a similar view of the end door of my device. Fig. 4 is a similar projection of the swing-valve used in my device. Fig. 5. is an isometric view of my device showing the swing-valve in position and the cleanout-oover removed, a portion of the case being cutaway to show interior. Fig. 6. is an isometric view of the cleanout-cover of my device.

Similar letters of reference refer to correspondingly like parts throughout the several figures.

My device may be constructed of either wood or metal but the latter material I consider preferable on account of its lasting Serial No. 444,180. (No model.)

qualities and I will therefore describe it as manufactured from such.

In the drawings 0, refers to acesspool which is made in the ordinary manner and forms a catch-basin with an outlet considerably above its bottom, with a connecting drain 13, entering the main sewer A.

It is in the outlet of the cesspool C that my device is placed and it consists of a box like case D having a flange h, cast thereon about midway of its length. This case D is constructed with an open end 0, which is inserted into the drain B at the outlet 'of the cesspool 0, as far as the flange h,and entirely fills or closes the outlet. The opposite end of the case D, is closed with the exception of a small opening G, into which a door G is fitted, and this opening G need be only sufficiently large to allow a rod to be inserted therein for the purpose of removing any 0b struction that would be liable to clog the drain B.

At the top of the case D is a large opening F, (which I shall term the cleanout-opening) fitted with a tight cover F; and directly under this cleanout-opening is another large opening I, which serves as an inlet for. the overflow or excess of water in the cesspool O.

Extending diagonally across the interior of the case D and hung from the upper corner of its closed end is a swing-valveE hinged in such manner as to entirely cover the inletopening I. A rib f, cast upon the interior of the case D, and extending entirely around the same formsa seat against which the valve E closes. This swing-valve E, forms a watershed for the purpose of diverting the water which is poured in to the cleanout-opening F, over the inlet opening I, when cleaning out the contents of the cesspool. And it servesa double purpose, for when the cover F, is put on it immediately traps the drain B and prevents sewer-gases from entering the cesspool even when the latter isempty.

It can now be readily understood that when a cesspool is provided with my device the water within the same will stand as high as the top of the lower rib f, of the valve-seat, before it will run into the drain B, consequently the inlet-opening I, is under water and neces sarily sealed against the escape of sewergases. A further seal is obtained through the swingvalve E which always remains closed upon its seat until the water in the cesspool O attains sufficient height to raise the valve and escape through the drain B. The object of this swing-valve E, was not to obtain a gas-check to prevent the escape of sewer-gases, although it assists the submerged inlet in accomplishing that result, but its utilization was for the purpose of closing the inlet opening I, and directing the course of water bailed into the cleanout-opening F when found necessary to clean out the cesspool. The cover F, of the cleanout-opening F can be sealed absolutely tight by having its edges cast to fit within grooves around the edge of the cleanout-opening. Then a little water poured upon the topof the cover would fill the groove suffieiently to close the intervening space between the cover a and top of case D.

Having described my invention, what I claim, and desire to secure by Letters Patent of the United States, is-

1. A cesspool outlet consisting of a case D having its open end and a portion of its length inserted in the outlet drain, said case having its opposite end closed and an inlet opening from its under side nextadjacent its closed end, a swing-valve extending from the upper corner of said case diagonally across the inlet opening, and a cleauout-opeuing provided with a cover, directly above said swing-valve, all for the purpose described and substantially as shown and set forth.

2. In combination with a cesspool and its connecting sewer-drain the improved outlet connecting the cesspool with said drain, consisting of a case D having its open end 1nserted in said drain and its opposite end MATTHEW MORIARTY.
