Application November 2, 1953, Serial No. 389,611

1 Claim. (Cl. 210-6) The present invention relates to a sectional septic tank, and more particularly to one which may be nested for convenience in shipping.

In many portions of the country the cost of septic tanks is higher than it need be. This is brought about by the fact that in the past metal septic tanks have been constructed in completed form, and hence they are bulky. This limits the maximum number of such tanks which can be placed on a truck. The weight of such tanks, how ever, is far below the hauling capacity of the truck. The cost of delivery of a load of such septic tanks must then be divided by the number of tanks carried, and hence where appreciable distances are involved between the manufacturer and the distributor, the freight costs are quite high. Accordingly in accordance with the present invention it is proposed to provide an improved sectional metal septic tank which may be nested so that the same truck which now delivers a certain number of tanks can carry three or four times the number now being carried. This would, of course, reduce the freight cost per unit tank appreciably.

In accordance with present practice of constructing metal septic tanks they are completed at the factory and are quite heavy. Because of their large bulk and appreciable weight it is necessary to employ several men to handle such tanks, even for installation on vthe job. It is proposed in accordance with the present invention to provide a sectional septic tank `so that the individual sections could readily be handled by a single man, both for delivery from his shop and for installation on the job.

It is further proposed in accordance with the present invention to provide a sectional septic tank which can be shipped in nested form together with all parts necessary for assembly of the tank including a quantity of sealing compound for the various joints between the sections. These sections would be in nested form so that by the simple expedient of a couple of metal straps a convenient nested package is obtainable.

It, therefore, is an object of the present invention to provide a new and improved sectional septic tank.

A further object of the invention is to provide an irnproved sectional septic tank which may be nested to save transportation costs.

A still further object of the invention is to provide an improved sectional septic tank to save labor and installation costs.

Other and further objects of the present invention subsequently will become apparent by reference to the following description taken in conjunction with the accompanying drawings wherein:

Figure l is a vertical cross section of an assembled sectional septic tank;

Figure 2 is a partial enlarged cross sectional view of a portion of the assembled tank;

Figure 3 is a horizontal cross section as seen in the direction of the arrows along the line 3-3 of Figure l;

Figure 4 is a side view ofthe assembled sectional septic tank;

nited States Patent O 2,764,545 Patented Sept. 25, 1956 ICE Figure 5 is a detailed cross sectional View showing the baie of the tank;

Figure 6 is a vertical cross sectional view of a nested tank ready for shipment; and

Figure 7 is a side view of the nested septic tank ready for shipment.

Referring to the drawing it will be noted that there has been provided a sectional septic tank having a top section 11 provided with a curvilinear side wall member 12 having an inlet 13 and an outlet 14. Secured within the top section 11 to the side walls in the vicinity of the inlet 13 and the outlet 14 are similar baffle members 1S and 16. The top unit has a cover 17 which is rictionally retained in position so that subsequently it may be removed in the event it is necessary to clean the septic tank.

The septic tank has a bottom 18 comprising a generally cylindrical side wall portion 19 and a flat bottom 20 welded thereto. Around the outside of the top edge of the side Wall portion 19, the bottom 18 is provided with a Z angle iron member 21 welded at convenient intervals so as to form a channel or annular trough around the outside of the bottom Wall 18. This channel or trough formed by the member 21 receives the cylindrical wall 22 of an intermediate section 23. The section 23 adjacent its upper edge is likewise provided with a Z angle iron member 24 to form an annular trough or groove for receiving the next section of the tank. The annular groove formed by the member 24 receives the cylindrical wall 25 of the next section 26 of the tank. The cylindrical wall 25 adjacent its upper edge is provided with another angle iron member' 2'7 to form thereabout an annular channel or groove, into which is fitted the side wall member 12 of the top tank section 11.

Figures 2 and 3 show in greater detail the manner in which the bailie members 15 and 16 may be secured in position in the top section 11. While for convenience bolts have been shown as being suitable fastening members, it, of course, will be understood that studs may be Welded on the inside of the wall member 12 and suitable bayonet slots or the like provided in the baffle members i5 and 16. The baille members are provided so that any sewage entering the opening 13 will not iiush out of the outlet 14 the sludge and bacteria which usually float at the top of the liquid level 2S shown in Figure l. This sludge contains certain yeast and bacteria which digest the sewage so that the iiuid from the outlet 14 is clear odorless water.

Figure 2 also shows certain details of the construction showing how the joints between the several sections are sealed by a suitable compound 29 which lls the annular grooves formed by the angle iron members Z1, 24, and 27 of the lower sections of the septic tank. The compound 29 is preferably a plastic material which will resist any decomposing action which may occur within the liquid aggregate contained within the assembled septic tank. It, of course, will be appreciated that any other sealing compound which is resistant to the action which takes place Within the septic tank may be used for sealing the annular joints formed by the members 21, 24, and 27.

Figures 6 and 7 illustrate the manner in which the sectional septic tank is nested for shipment. The top section 11 serves as the bottom container for shipment, and info it is placed the two batlie members 15 and 16 and a carton or container 31 of sealing compound such as the compound 29 shown in Figure 2. Within the top section 11 then is placed in upright form the intermediate section 26, into which is then inserted another intermediate section 23, and inally the bottom section 18 is placed in position. All these sections are inserted in upright form so that the bottom 20 of the bottom section serves as a retaining cover to hold in position the baille members `15 and 16 and the lcarton 31 of sealing compound or material. `It is suggested that two metal bands or straps 32 and 33 at right angles to each other extending diametrically across the nested tank sections would serve to retain the sections in position for convenience in shipment. After delivery of a l,package such `as shown in Figure 7 to the individual who handles and installs septic tanks, the retaining straps 32 and 33 may be removed in the event that only one man is available for loading the tank on a truck for delivery to the ultimate place of installation. Each of the sections in nested form can be handled individually and placed on the truck, and hence even at this point appreciable labor may be saved. When the tank has been delivered to the point of installation, it, of course, is quite convenient for a single individual to 'handle the various sectional parts and to install in position the bottom section 2t] and apply the compound, and ythereupon add successive sections of the tank until the installation has been completed. Hence itis unnecessary to have-a plurality of men present to put the septic tank in position.

While for the purpose of illustrating and describing the present invention certain preferred arrangements have been shown, such as a cylindrical configuration for the sections, which might be ellipsoidal, or other convenient configurations, it is to be understood that such variations are contemplated as may be commensurate with the spirit and .scope of the invention set forth in -the accompanying claim.

I claim as my invention:

A sectional metal septic tank formed of a plurality of sections of cylindrical shape and similar height, and com prising a bottom section having cylindrical side walls and a closed bottom, a Z-angle iron member welded to and surrounding the outer circumference of said wall at its upper edge to form therewith a peripheral channel, an

intermediate section having cylindrical side walls of larger transverse dimensions whereby the lower edge thereof will rest in the middle of the peripheral channel of said bottom section, a Z-angle iron member welded to and surrounding the outer circumference of the upper edge of said wall to form therewith a peripheral channel for receiving in its middle the bottom edges of the wall of another intermediate section, a second intermediate section similar to said rst intermediate section but of greater transverse dimensions, and a top section having cylindrical side walls provided with an inlet and an outlet, said walls having a transverse dimension greater than that of the intermediate section upon which it is to be supported, a friction t cover for said top section, said top section having diametrically opposite arranged inlet and outlet each provided with a removable baffle extending from the top edge to the bottom edge of said top section, said top section when inverted is to receive in normal upright position all the remaining sections in order proceeding from the top whereby the underside of the Z-angle member of each successive section rests upon the peripheral edge of the next larger section until the bottom of the bottom section forms with the nested intermediate sections and the top section ka chamber for storing said bafes and parts therefor for shipping.
