Application med Januaryisc, 192e. ,serial No.,a4,972.

This invention relatesito sewage purii-` cation or distributing devices, particularly to septic tanks, and has for its object the two tanks in series, both possessing many featuresl inv common, and the two notonly operating-to destroy the solid matter 1n .the

sewage but acting also to carry off any gases' which may form'during decomposition, the endmost 'one of the rseries being of course provided with a seepage outlet buriedvwithin the ground for carrying off'the matter.

Another object of the invention'is `to lpro# vide a .septic tankprovided internally with means operating to prevent undue agitation of the contents in case of a rapid How of waste matte-r into the tank.

An additional object is the provision of a device of this character which will be simple andl inexpensive in manufacture, easy to install, positive in action, efficient and durable in service, and a general improvement ir the art. Y j l l j With the above and other objects and advantages in view, the invention consists in the details of construction, and the arrangement and combination of parts to be hereinafter more fully described, and claimed, and illustrated in the. accompanying drawings, in which Figure 1 is a vertical section taken through a pair of septic tanks arranged in tandem, one receiving from the other,

Figure 2 is a plan View of one of the tanks with the cover removed, and

Figure 3 is a vertical cross section taken on the line 3 3 of Figure 1.

Referring to the vdrawing in detail, the numerals 10 and 11 designate, broadly, the two septic tanks which are arranged in series or tandem. These two tanks are, in most respects, similar but they do possess certain features of difference as will ber brought out hereinafter.. It should, however, be stated vthatboth tanks are preferably constructed of concrete and while it is true that they may be of any desired size and shape, it is preferable that they be cylindrical and of vsuch size as to be capable of being transving within the ground. y n prises a body`1'2l formedat opposite 'sides of ported from the place ofy manufacture to wherever their use is needed. v `This feature'is of importance inasmuch as`the1"eare "certain tanks inexistence which arev incomplete' cwing tothe, fact that `they rmust' be equipped with a ibttoni subsequent to "their 1`n`o`untitsfinterior' witlrprojections 13 andf14fwith 1n vthe former of which is embedded a ldownwartlly extending' elbow l15 with `which vconnests the waste lpipe 1G `leading"fromthe plumbing systemjin a house'or otl1er-bu1ld1ng.

fWithin the enlargement 14 is `embedded a` "fi" "17 which has its two" opposite branches exe f tending vertically' and which" has: itslremztin` "in'g branch1 1'8,extending'horizontally to l or 'fthrougli'ithe 'side wall of the body 12v for `connection with an' outlet' pipe 19 which leads to `thetankl 11, as will bedescribe'd. `Iheta-nk 10 1s equipped with `a"removable `cover 20 equipped 1 with a lifting'ring 21'where'by'5it f may be removed when access is needed to the tank 10. `Attention isfdirected to the fact that the projection 14 and also the pipe 17 terminate at a point belowthe lower surface of the cover 2O so as to provide aspace 22 through which any gases rising `from the decomposing matter within the tank body 12 may pass sov as to enter the T 17 and `pass out through the pipe 19.3 Obviously thetank h body 12 may contain any suitable liquid containing disinfectant or vchemicals calculated to destroy the waste matter entering the tank. This feature is common to both tanks and under some systems it is of course true that the second tank maycontain a different l n liquid or chemical from what is contained in the first in order to exert a still further purifying action.

The tank 11 comprises a body 28 substantially the same as the body 12 and formed with enlargements 24 and 25 the latter of which contains a T 26 embedded therein in identically the vsarne manner as the T17.

However, the enlargement 24 hasembedded l13 of the tank body 12, the purpose being that the lT 27 Vwill permit gases entering through the pipe 19 to pass directly upto the top portion of the tank body 23 so as to pass to the discharge T 26 without having tol bubble through the water or other liquid within the tank body 23. The pipe 19 constituting the outlet `from the tank 10 is, of

Y of the T 27, and a discharge pipe28 is con` v io course connected'in the intermediate branch nected with the corresponding intermediate branch of the T 26, `this discharge pipe 28 forming or being ,connected with a seepage pipe which is of course buried Within a suit able trenchv within the ground so as to dis.

tribute the matter passing from the tank. There; isan impO-rtantjieature, common to both tanks, namely a transversely extendying vertical partition 29 which, in actual practice, maybe a slab of concrete, stoneor the like,fhaving its end portion fitting with guides '30 on the inner walls of thetank and having its lower edge litting within sockets v .or teeth lwhereby this slab Vwill be retained in position.` This slabtermmates at a point below' thewater level 32 and is provided for the purpose of preventing undue agitation of the water or .other liquidv in case waste mattery enters the tanker tanks with l considerable violence or force.l

H From the foregoing 4description and a study of the drawings, it will beapparentlthat I have thus provided a simply conl VAstructed,k inexpensive and yet highly efficient septic tank structure which may be used in seriesor individually if desired and which will act-most eiciently to promote sanitation.'k It vis believed that` the construction, A' i operation and advantages will be readily apparent to one skilled in the art without Jfurther explanation.

"While I have shown and described the i preferred embodiment of the invention, it should be understood that I reserve the right to make such changes inthe form, construction'v and arrangement of parts as will not depart from the spirit of the invention or the scope of the subjoined claim.

`Having thus described the invention, I

rclaim A septic tank comprising a hollow body n having anopen top normally closed'by a ren'io'vable cover fitting thereon, said body ,being provided internally at "diametrically opposite points with enlargements, an inlet pipe member embedded withinv one enlargevnient and having its discharge end directed downwardly, a T embedded within the other In testimony whereof I affix my signature;l f
