Be it known that I, WILLIAM A. Mo- Kmen'r, a citizen of the United States, residing at Alexis, in the county of Warren and State of Illinois, have invented certain new and useful Improvements in- Septic Tanks, of which the followin is a specifica-. tion, reference being had to t e accompanyin drawings.

. his invention relates to septic tanks and has for its principal object the provision of a tank of the above stated character whereby the sewerage contained therein will be thoroughl and efiiciently catalyzed.

A t urther object of the invention is the provision of an apparatus of the foregoing character comprising a series of compartments communicating with one another and a system of pipes whereby the lighter and heavier constituents of the sewerage may be separated, dissolved and deodorized by oxidation.

A still further object of the invention is the provision of a hermetically sealed septic tank comprisinga series of. compartments separated by partitions and means for carrymg llOXlOlIS gases from the inlet compartment direct to the outlet compartment, thus providing a separate exit for the gas from that of the sewerage to the outlet compartment.

With these and. other objects in view as will appear as the description proceeds, the invention comprises various novel features of construction, combination and arrangementof parts as will be more fully described hereinafter and set forth with particularity in the appended claims.

Referring to the drawings Figure 1 is a plan view of'm'y improved septic tank showing the cover thereof removed; Fig. 2 is a vertical longitudinal sectional view of the tank; Fig. 3 is a transverse sectional view taken on the line 33 of Fig. 2; and Fig. 4 is a detail perspective view of one end of one of the overflow troughs. m

By referring to the drawings, the reference numeral 4 will be seen to designate a tank constructed of concrete or masonry walls. These walls consist of end walls 2 and 3 respectively, side walls 4, a bottom 5. a top or cover 6 and intermediate walls or partitions 7 and 8 respectively, dividing the tank into a serles of compartments A, B

and C.

The, bottom of the tank is formed adja- Speclflcation of Letters Iatent. Application filed August a, 1912. Serial no. 719,121.

groove 9 and is adapted to receive the tongues 10 formed on the lower inner edge of the end and side walls. The opposite vertical edges of the side walls 4 are recessed 'to form grooves 11 and are adapted to recelve the opposite vertical edges of the end walls 2 and 3.

Arranged transversel overflow troughs 12 an are provided upon their ends and bottoms with tongues 13 and 14 which are adapted to seat within corresponding recesses 15 and 16 formed in the bottom 5 and the side walls 4 respectively.

of the overflow trough 1s V-shaped channel 17 which extends through its length to points adjacent its opposite ends. Grooves 18 extend from the terminal ends of the channel 17 through theupper face of the overflow trough 12 through the ends of the latter and are adapted to receive the lower longitudinal edges of the partitions 7 and 8.- The side walls 4 are provided at spaced intervals with vertical grooves 19 adapted to receive the opposite vertical edges 20 of the partitions 7 and 8.

The upper face provided with a The cover 6 is also provided in its under face 7 adjacent its peripheral edge with a continuous groove 21 adapted to receite the tongues 22 upon the upper inner edges of the end walls 2 and 3 and the side walls 4:, whereby said tank may have its cover hermetically sealed thereon. The cover is also provided 1n 1ts under face wlth transverse grooves 23 adapted to receive the upper edges of the of the tank arepartitions 7 and 8 whereby each of the compart-ments A, B and C maybe hermetically sealed from one another. An inlet sewer pipe 24 enters the tank through the end wall 2 and extends down into the compartment- A and terminates at a point below the level of the surface of the sewerage contained within the tank. A11 overflow pipe 25 enters the compartment C throughthe rear end wall 3 and terminates at a point below the surface of the sewerage. Arranged within the compartment C and surrounding the overflow pipe 25 is a suitable wall 26 which may be formed of masonry or any other suitable material. This wall extends upward to a point slightly above the lower end of the overflow pipe 25. A pipe 27 extends from the compartment A through the partitions 7 and 8 and into the compartment C, thusestablishing a direct communication between ions gases accumulating withinthe compart-' erage flows in through the inlet pipe 24 into the compartment A where the heavier constituents are arrested by the overflow trough 12 whereas the lighter can pass over the overflow trough and beneath the lower edge 1on7 into the compartment B;

of the-partit or more dense constituents in the heaviercompartment B will descend and be arrested by the other overflow'trough 12 and the lighter will pass over the overflow trough l2 and beneath the partition 8 into the compartment G whereagain the heavier constituents will descend and be arrested by --the wall 26, the lighter or remaining portionof' the sewerage passing over the wall 26 and out throu h the overflow pi e 25.

From t e foregoing descrlption taken in connection with the accompanying drawings, the advantages of construction and the method of operation willbe readily apparent to those skilled in the art to which the invention relates, and while I have described the principle of operation of the invention, to ether with the 'device which I now consi er to be the best embodiment thereof, I'

desire to have it understood that such changes may be madewhen desired, as are within thescope of the appended claims,

Having thus fully described my invention what I claim as new is: 1. A septic tank, comprising a series of; compartments separated by partitions, troughs arranged below said partitions, the top of each of said/troughs being formed with cent-rally dis osedlongitudinal grooves at its opposite en s for the reception of the bottom edges of said partitions, an inlet pipe communicating with one of said compartments, and an outlet pipe communicating with the last consecutive compartment.

2. A septic tank, com compartments, separate by partitions, a trough arranged beneath each of said partitions, the side walls and the bottom of said troughs being formed with longitudinal centrally disposed ribs, said ribs adapted to enrising a series of trough arranged I Lemon-7 ga e corresponding grooves in the bottom an side walls of said tank, whereby said troughs are'held in position in said tank, an inlet pipe for one of said compartments, and an outlet pipe for the last consecutive compartment.

. 3. A. septic tank com rising a series of compartments sepgrate by partitions, a

titions, eachof said troughs being formed upon its upper face with centrally disposed longitudina slots at its opposite ends, the

lower edges of said partitions adapted to rest in said slots whereby the upper edges of the troughs .are arranged in a plane slightly above the lower edges of the partitions, a

pipe extending through said partitions establishing direct communication between the I first and last consecutive compartments, an inletpipedor one of said compartments, and an outlet pipe for the last consecutive compartment.

4. A septic tank, a cover for said tank,.the

tank being provided with .a series of con secutive comipartments separated by partitions, each 0 said partitions terminating at a point above the bottom of the tank, an overflow trough arranged beneath said partition, the upper longitudinal edges of the latterprojecting upward to a point slightly above the lower edge of the artition, a pipe establishing direct communlcation between the first and last of said consecutive compartments, an inlet pipe entering at the top and depending into one of said com artments, an overflow pipe entering an depending into the last consecutive compartment, and a wall arranged within this latter compartment around I the lower depending end of the overflow pipe, said wall projecting upward to a point slightly above the lower end of theoverflow pipe and above and beyond the level of the overflow trough.

In testimony whereof I hereunto affix my signature in the presence of two witnesses, 9;
