Abstract
ABSTRACT OF THE DISCLOSURE
A mounting means for an elbow pipe in a septic tank consisting of a keyway made in the top wall of the tank and longitudinally aligned with a circular opening formed in an end wall adjacent the top wall of the tank. The elbow pipe has a key adapted for outward sliding engagement in the keyway. The elbow pipe fits within a sealing gasket adapted to snap into the circular opening of the end wall and its end portion is threaded. A connector sleeve is screwed on the end of the elbow to secure the elbow within the gasket and to receive a drain pipe glued within the sleeve.

Description
FIELD OF THE INVENTlON iZ~95~
The present invention relates to septic tanks and fixtures therefor, more particularly to an improved novel way of mounting a pipe in a septic tank.
BACKGROUND OF THE INVENTION
Till now, connecting pipes and elbows for septic tanks have been mounted either loose or with gaskets in holes of the tank. The elbows were difficult to install within the tank and the joints between the septic tank, the connecting pipes and the elbows are often not leakproof.
OBJECTS OF THE INVENTION
In view of the above, it is a first object of the pxesent invention to provide a pipe connector and elbow assembly which is easily and quickly fittable to the wall and ceiling of a septic tank in a completely leakproof manner.
It is another object of the invention to provide an assembly of the above type, which is non-costly to produce.
Another object of the invention is to provide an elbow which can be easily cleaned when plugged.
S~MMARY OF THE INVENTION
The above and other objects and advantages of the present invention are realized according to a preferred embodiment comprising a septic tank and a hollow elbow. The septic tank has end walls, side wa]ls and a top wall having an orifice and cover provided therein. One or both end walls are formed with a circular opening immediately below the top wall.
The latter has, formed therewith, an elbow mounting means extend-ing inwardly away from and lonsitudinally aligned with the circular opening of the end wall.
0 The elbow has an outer end which is adapted to engage the circular opening of the septic tank. The other sur-face of the elbow adjacent its opening is provided with seal~ing ~/.~jr , - 2 -12795~3'7 means arranged to make a leakproof connection when the elbow is in place The upper surface of the elbow inwardly of the seal-ing means is provided with an elbow mounting member which is complementary to the elbow mounting means.
~ In order to secure the elbow to the septic tank, a worker has simply to lower the pipe through the orifice capped by the cover and, then, by sliding the mounting member into the elbow mounting means, push the pipe until it engages the septic tank end wall opening. The sealing means can be installed in said opening either prior or after elbow insertion.
BRIEF DESCRIPTION OF THE DRAWINGS
The above will be clearly understood by having referral to the preferred embodiment of the invention, illus-trated by way of the accompanying drawings, in which:
Figure 1 is a side elevation of the invention, the septic tank being vertically sectioned and partly shown;
Figures 2 and 3 are sectional views taken along lines 2-2 and 3-3, respectively/ of Figure l; and Figure 4 is an enlarged vertical section of the connector and gasket in position on the tank, the latter and a connecting pipe partially shown in dotted lines.
Like reference numerals indicate like elements throughout the drawings.
DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT
Septic tank 1 has an end wall 2 which is horizon-tally and/or vertically corru~ated and which merges with both side walls (not shown) and a transversely-convex top wall 4 having an orifice 3 and a cover (not shown). The uppermost two corrugations 2' have between them a circular opening 5 made in each end wall 2.
Outwardly of top wall 4 the upper part of tank 1;~97~iS~3~
1 is formed with the elbow mounting means disclosed above.
The means consists of forming top wall with an elongated longitudinal keyway 6, which is cross-sectionally in the general shape of a T and has a slot 6'.
A pipe elbow with a curved part 8 is adapted to be supported under keyway 6 by a complementary T-shape key 9. The latter has a leg portion 9' slidable in slot 6' and is rigidly secured to or integrally made with elbow 7. The latter, as well as tank l, are preferably made of a thermo-pl~asticr tank l preferably by rotary molding, and elbow 7 preferably by blow molding.
Inwardly of member 9, elbow 7 is provided witha fin lO, which may be used to displace the pipe elbow. As shown in Figure 3, fin lO forms a funnel opened at the top and communicating with the inside of elbow 7 through elbow side opening 7'.
secause funnel-forming fin lO registers with tank access opening 3, it is easy to clean elbow 7 through fin lO
and opening 3 by the use of a suitable tool, whenever elbow 7 becomes clogged.
The tank end wall opening 5 is provided with the sealing means, consisting of an annular sealing gasket 11, made of elastomeric material and which has a central annular groove ll'. This annular groove is intended to receive the circumferential edge of the circular opening 5 of end wall 2. Gasket 11 has inner spaced lips 11''.
Elbow pipe 7 has an outwardly-facing step 7' followed by a tapered portion 7'', in turn followed by a smaller diameter extension 7'" , the-latter being externally threaded An inwardly-threaded connector sleeve 12 is screwed on extension 7''' and secures elbow 7 in position with gasket 11 sandwiched between step 7' and sleeve 12. A drain pipe P is l~7ssa~
fitted and glued within sleeve 12. sOth ends of the tank can be arranged with the system of the invention, one pipe serving as an inlet and the other as an outlet.
This invention is applicable, inter alia, to the septic tank described in applicant's Canadian patent No.
1l080,862,dated July 1, 1980, and also to holding tanks.
