SEPTIC TAN K.

Application filed February 25, 1926. Serial No. 90,619.

The present invention relates to sewage tanks, particularly for domestic purposes, though not necessarily limited to such use. The object is to provide a simple and prao tical structure that can be made up of units that may be duplicates, these units having means of communication, that are simple and will permit the flow of sewage from one to the other, at the same time also allowing free venting and thus eliminating the danger of the collection of gas.

In the accompanying drawings:

Figure 1 is a. horizontal sectional view of the preferred embodiment of the invention,

Figure 2 is a side elevation, partly in section, and

Figure 3 is a perspective view of the upper portion of one of the units.

lVhile any number of units may be employed, the present structure discloses two. These are in the form of containers 3 that are preferably of concrete. As the units or containers are duplicates, a description of one will serve for both.

The unit is provided with a generally cylindrical wall, the interior being preferably a true cylinder. It is provided on one side wit-h a vertically disposed enlargement 4, having preferably a flat external surface 5. Centrally through this portion is formed an opening 6. Channels are located in the fiat surface. These channels have vertical portions 7 on opposite sides of the opening 6, and a transverse portion 8 connecting the vertical portions below the opening 6. The

channels may or may not extend below the cross channels 8, though they preferably do, as shown at 9 in Figure 3. The container furthermore is preferably provided, diametrically opposite to the opening 6 with another opening'lO, into which either a supply pipe 11 may extend, or from which a delivery pipe, as 12, may lead. The various openings 6 and 10 are surrounded at their inner ends by scum check walls 13. These walls are preferably integral with the walls of the container and may be of various con figurations. They terminate short of the top and bottom of the container, and form passageways 14 that are freely openat their upper and lower ends.

The units or containers are of course separately constructed, and in assembling them into a sewage tank the flat surfaces of two pipe 1.1, flow freely from the first tank into the second, and thence to the outlet. 12, but that air or gas can pass from one unit to the other over the upper ends of the scum check walls 13. As a consequence the tank can be completely vented.

From the foregoing, it is thought that the construction, operation and many advan tages of the herein described invention will be apparent to those skilled in the art, without further description, and it will be understood that various changes in the size, shape, proportion and minor details of construction may be resorted to without departing from the spirit or sacrificing any of the advantages of the invention.

What I claim, is:

1; A sewage tank, comprising a plurality of containers having abutting surfaces and alined openings through the surfaces, forming pipeless means of communication between the interiors of the chambers, said surfaces having alined channels extending around said openings for the reception of a connecting binder.

2. A sewage tank, comprising a plurality of containers having abutting surfaces and alined openings through the surfaces, forming means of communication between the in teriors of the chambers, said containers having interior scum check walls integral with the side walls and extending around the openings, forming-chambers that are freely open at their tops and bottoms, and said abutting faces having external alined channels extending around said openings for the reception of a connecting binder.

3. sewage tank, comprising a plurality of containers having substantially cylindrical chambers and enlargements'on the outer sides formed with substantially fiat surfaces, said enlargements having alined openings that constitute pipeless means of communication between the chambers, and said surfaces having alined channels around and beneath the openings for the reception of a connecting binder and packing, and said containers having on the inner sides of the enlargements and integral therewith scum check walls surrounding the openings and terminating short of the tops and bottoms of the containers, forming open ended passageways to the openings.

In testimony whereof, I afiix my signa ture.
