Description
~ 7~ ~ .
This invention relates generally to dr~in structures and r,ore particularly to a drain fitting which may be used with fiber-glass or other types of molded~ pre-formed or pre-assembled shower stalls or bases~ sinks or tubs, or various similar r~cep-tors requiring the use of a drain fitting.
Various types of drain fittings are known in the art and insofar as is known~ most o these are characterized by ~ariou~
disadvantageous eatuLes. Among these are: the attachment of the drain pipe directly to the strainer barrel to which the s~rainer plate is attached so ~hat if the upper surface ~ the receptor is d~aged or the gasket needs replacement, the drain pipe would have to be cut and the entir~ unit removed for repair;
the abs~nce o~ secondary drainage means in the case of leaks or damage, and an excessive cost initially, an~ in labor and repairs~
1~ Accordingly, the main object of the pxesent inven.lon is to provide an i~roved drain fitting which will obviate the above and other disaavantageous ~eatures.
An impo~ an~ object of the present invention is to provide an improved ~rain fitting which may be installed in a shower stall receptor or base at the factory, or o~ the site before or after ~he receptor is installed.
A further important object of the present invention is to provid2 an ir~?roved drain fitting in which the strainer barrel portion may be removed fro~ the base connector and the upper sur~
face of the receptor without cutting pipe or going to lower levels OL a building~ etc. for repair or replacement of the strain~r barrel or gasXe, thus saving material amounts of time and labor~
A still rurther object of the present invention is to provide an improved drain fitting advantageously formed of plastic so as to be easily and simply installed by solvent welding instead of the time cons~-.,ing and expensive operation o~ leadinc~; etc~ in conventional units.
, ~3~
Broadly speaking the above objects are me-t by the present invention which provides a drain fitting for connecting the drainage opening or receptor of shower ~talls, etc. with a drain pipe comprising, in combination, a base connector having a lower shouldered portion to be mounted on the upper end of a drain pipe closely adjacent the receptor and a flanged, upper portion; a drainage barrel having a peripheral f:Lange insertable into the upper portion; a drainage plate mounted on the barrel; means connecting the base connector and the barrel so as to force the flanges thereof into sealing engagement with the edges of the receptor;
the connecting means comprising relatively rotatable mating threaded portions; and vertical slots formed in one of the threaded portions to provide secondary drainage means to the drain pipe.
The above objects are also met by the present invention providing a drain fitting for connecting the drainage opening or receptor of shower stalls, etc. with a drain pipe comprising, in co~bination, a ~ase connector having a lower shouldered portion to be mounted on the upper end of a drain pipe closely adjacent the receptor and flanged, upper portion; a drainage barrel having a peripheral flange insertable into the upper portion; a drainage plate mounted on the barrel; and means connecting the base connector and the barrel so as to force the flanges thereof into sealing engagement with the edges of the receptor; the connecting means co~prising headed bolts mounted in the base connectorl and a flanged clamping ring having interior, barrel-receiving threads and bolt-receivins openings therein for clamping the flange of the ring to the connector.

Figure 10 is a vertical sectional view thereo, taXen I on the line lO-10 of Fig. 9; and Figure 11 is a central vertical sectional view of the parts assembled in operative position on a shower stall base, etc.
As shown in Figs. 1-5 inclusive, the drain fitting comprises a base connector lO~a pair of gaskets 12 and 14, a strainer barrel 16, and a strainer plate 18 r all.adapted when in operative position in a receptor 20 to comprise an improved~
long-lasting device of ready maintenance.
As will appear, the strainer assembly which is exposed to ,, .
, -2a-7~i ~
daily use and is more subjec-t to damage may be replaced or repaired without cutting pipes, going to lower levels, or removing parts of the structure for repair or replacement from beneath the receptor.
The drain fitting design is produced by molding, casting, etc. of a suitable plastic which may be utilized with fiberglass or vari-ous other types of molded, pre-formed receptors or openings in shower stall bases, etc.
The base connector 10 is reàdily solvent welded to plastic DWV pipe P of various materials and as shown, fits 2- or 3-inch -pipe for seating either of which positive stops in the ~orm oE
shoulders 22 and ~4 are respectively provided. The base connec-tor 10 is interiorly threaded and is provided with an upper peri-pheral flange 26 for the support and compression of the gasket 12, and is provided thereunder with a plurality of spaced lugs 28 for engagement by a wrench.
The strainer barrel 16 is exteriorly threaded and includes a plurality of circumferentially spaced f recessed slots 30 therein to provide secondary drainage into the pipe P instead of to lower areas in the structure in the event that either gasket 12 or 14 is damaged or deteriorates. The barrel 16 is also provided with a peripheral flange 32 which compresses the washer 14 against the receptor ~0, and with inner diametrically positioned circular threaded bosses 34 which are countersunk for reception of anti- -corrosion screws 36 to enable flush mounting of the strainer plate 18.
Thus, the drain fitting of the present invention provides a base connector 10 for a welded connection to a drain pipe P which is installed beneath the receptor 20 and allows the strainer assem~ly 16 r 1~ which is threaded into the base connector to be removed from above the receptor. This is an important feature of the invention.
Anothex embodiment of the invention is shown in Figs. ~-11 inclusive wherein like parts ha~e been given like numbers. The 75~
essen-tial diff~rence between this and the preceding emhodiment is that instead of screwing the base~connector and strainer barrel assembly together to compress the washers 12 and 14 against the receptor 20, a clamping ring is provided for the purpose in order to eliminate any possibility that the liner or waterproof membrane employed is crimped or wrinkled during installation.
The upper surface of the base connector 10 (Figs. 6-11 inclu-sive) is provided with four spaced and threaded bolt holes 40 for the reception of headed bolts 42 and with a peripheral upstanding rib 44 on the flange 26. Intermediate the bolt-receiving hole 40 and the rib 44 is a circular groove 46.
A bolt clamping ring 48 is interiorly threaded for mounting on the strainer barrel 16 (which is unchanged), and is provided with a flange 50 having a depending peripheral rib 52. This rib 52 (Fig. 11) cooperates with the groove 46 of the ba~e connector 10 to sealingly clamp a waterproof membrane 54 therebetween. As seen in Fig. 8, the bolt clamping ring 48 is also provided with radial, secondary drainage channels 56 and bolt-receiving holes 58. One end of each of the holes 58 is enlarged as at 60 to per-mit passage of the heads of the bolts 42.
In a typical installation of this embodiment of the drain fitting (Fig. 11) where the receptor comprises a liner or water-proof membrane 63 supported by subflooring 62, th~ base connector 10 is inserted through the xeceptor opening from above and is solvent welded to the top end of a drain pipe P which abuts one of the shoulders 22, 24 depending upon its diameter.
; The flange 26 of the connector rests upon the subflooring 62 and the waterproof memhrane 63 is now positioned thereon and closely encircles the four bolts 420 The clamping ring 43 is now positioned over the bolt heads by the bolt hole portions 60, and the ring i5 turned to move the bolts into the hole portions 58 and the bolts are tightened so that the clamping rib 52 tightly clamps the waterproof membrane 63 into the 1~3 ~S~
base connector groove 46 to effect a seal, the washers 12 and 14 being dispensed with. The strainer barrel 16 and its drain plate 18 are now screwed down into the clamping collar 48 to define the drain level of the installation. Thereafter the cement 64 is poured onto the membrane 63, the tile setting bed 66 is positioned and the tile then positioned thereon.
It will be noted that if for any reason, any moisture pene-trates the installation, it will pass inwardly by means of the drainage channels 56 and downwardly between the clamping collar 48 and the base connector lO into the drain pipe P. The secondary drainage channels provided by both embodiments are an important feature of the invention in preventing leakage damage and result-ant repairs.
It is to be understood that the forms of my invention here-with shown and described are to be taken as preferred examples ofthe same and that various changes in the shape, size and arrange-ment of parts may be resorted to without departure from the spirit of the invention or the scope of the subjoined claims.
