SEPTIC TANK.

if Application filed September 1, 1326 Serial No. 133,004.

This invention relates to new and useful mprovements in septic tanks and has for its primary ob ect to provide a tank comp-rising a pair of casing half sections in which i is arranged a partition wall resulting in the provision of a plurality of compartment-s within the tank having communication with each other at the-upper end thereofso that the material may flow from one compartment to the other, means being provided within the tank to cause'the excrement tofseek the bottoms of the compartments so as to be come properly disseminated. I A further object is-v to providei a septic tank of this character that may be readily set up in an opening in the ground and wherein the edges of the tank sections may beproperly sealed together so as to prevent the leakage of the fluid therethrough.

Other objects and advantages of the invention will become apparentas the nature of the invention is better understood, the

same comprising the novel form, combinathe cover thereof being removed.

Figure 3 isa detail vertical section taken substantially upon the line 3 3 of Figure 1, and a Figure 4 is a perspective of one of the shield members, per se;-

Now having particular reference to the drawing there is disclosed a septic tank that consists of apair of semi-elliptical sections 55 of predetermined length and width, the

opposite vertical edges thereof being flanged V as at 6-6 while the ends of the flanges are flared outwardly as at 7-7 in Figure 2. Arranged vertically between the sections 55 is a partition wall 8, the opposite edges of which extend between the flanges 66 of the sections after which the sections and partition wall are'interconnected by reason of a bolt and nut connection 9 passlng through the flanges of the sections 5+5 and alsothe opposite vertical edges of thepartition 8, asi-s shown in Figure 2. l

After the sections and the partition wall have been interconnected, there is arranged over the. flared edges 7+7 of the section flanges 66 vertical spring metal tubes 10%10, the inner sides ofwhich are formed with slots that extend throughout their length in order that these tubes may be sprung intoposition over the flared ends of the flanges and he maintained in proper position thereon by reason of the tubes springing together within said flared ends'of the flanges. Preferably after these tubes'have been arranged in position, concrete or other suitable material is poured therein while in a plastic state andwhen hardened forms a leak proof joint or seal between the edges of the sections 55 and the surfaces of the partition wall 8. I

Arranged fordetacha-ble disposition upon I the upper open end of the tank is a slip type cover ,11, and formed in the sections 5-5 at the upper ends thereof and also within the partition wall 8are circular openings. 12 in registration with each other as clearly indicated, in 'Figure 3.; Arranged within theopening 12 at oneside'o'f thetank is the usual sewerage pipe '(not shown),:

while arranged within the opening of the other tank section is a waste pipe (not shown), that is extended to any desirable point for drainage. I

Upon the interior of the tank adjacent the openings 12 inthe sections 55 thereof are 7 depending arcuate shaped metallic shields 13, while'at opposite sides of the opening in the partition wall 8 are similar shields. The

upper ends of the shields 13 adjacent the openings in the tank sections are formed with vhooks let-14 for engagement over the upper edge of the respective tank section. The shields 13 on the opposite sides of the opening in the partition wall 8 are inter connected at their upper ends as at 15 so as to permit the same to be hung upon the upper edge of said partition wall. 1

The length of the shields 13 is such that the lower ends thereof extend considerably beneath the openings 12 in the tank sections and partition wall so as to cause the solid matter ventering the compartments of the tank to pass, beneath the surface of the fluid level therein and sink to the bottoms of the compartments at the same time permitting the proper flow of the fluid into and out of said compartments.

in actual practice, a base of concrete or 6 other suitable hardening plastic material 16 is laid within the hottom oil the ground openinn and before the same hardens, the septic tank is forced therein as indicated in Fig;- ure 3 so as to provide a bottom wall for the tank.

,ltrwill thus be seen that l have provided a highly novel, simple, and e'lticient form of septic tank that is Well adapted for all the purposes heretofore designated, and even though hare herein. shown and descrihed the invention as coneistinn' of certain detail structural elements, it is nevertheless to he understood that some c anges may he made therein without elt'ertinn" the, spirit andseope ol the appended claims.

l-larine; thus deserihed the invention, what l claim as new and desire to secure by Lettors Patent is 1. In a septic tank oi the ciaos described. a pair ot? complementarr halt sections. lat: orally extending tlanges i iltttitl on the vertiral side edges of the sections. :1 vertirzl partition wall arranged between the sections, the edges Of the partition heinn disposed heilii tween the inner opposed fares ot the later- :rly extending flanges, securingmeans extending: through the lateral flanges and the edges ot the Yerti 'al partition wall, vertical tuhea arranged over the lateral ltaunes ot the sect ions and the edge portions ot the partition wall for receiving a sealinn material, said sections and the partition being formed with opei'lings inthe upper end portions, and ehieldn arranged within the tank adjacent the openings for Causing the material howing into the compartments of the tank to pass downwardly therein.

2. In a septic tank of the class described, a pair of complementary halt sections, late ally extending flanges formed on the vertiral side edgesof the sections, a vertical panition wall ar 'anged hetween the sections, the edges of the partition heing disposed he tween the inner opposed faces of the laterall extending flanges, securing" means extending: through the lateral flanges and the edges ot the vertical partition wall, verti :nl tuhes arranged over the lateral [hinges oi? the sections and the edge portions of the litliltltlll wall for receiving a sealing material, said sections and. the mrtition heine; lot-med with openings in the upper end portions. and shields arrangei t within the tank a tjaeent the openings for causing; the material 'ttowinn' into the compartment oil the tan-ii to pass downwardl therein. each of said shields heine' arcuate shaped in cross within and open at its respective ends, and haolis termed on the upper end of each shield l'or detachable ei'igagrement with the upper edge oi the tank and partition wall respectively.

Ii. In a septic tank of the class descrihed,

a, receptacle provided with inlet and outlet openings in the upper portion thereof, areaan shaped shields open at their res jieetive ends end adapted ;l':or disposition within the reeeptarle adjacent; the inlet; and outlet openinns respectively for musing the material to tlow dmi'nwardly into the receptacle, and hooks -formed onthe upper end oi? inch ehield "tor detachable engagement over the upper edge oil? the receptacle.

in testimony whereof I atlix my signature.
