This invention relates to improvements in plumbing fixtures, a particular purpose being to provide a floor drain so designed that seepage will effectively be disposed of to T which end it consists of the constructions,

combinations and arrangements herein described and claimed.

'An object of the invention is to provide the body of a drain with, seepage channels which at one end have communication with the drain pipe and at the other endare' open to points outside of certain fittings that vare used in the installation of the drain, so that water percolating aroundysuch fittings Will find its way into the drain pipe.

A further and important object of the invention is to employ a clamp for the double purposes of securing a water-proofing material such as tarredpaper to the flange of the strainer body and guarding the seepage channels in said body so that the latter cannot become obstructed when the drain is embedded in a plastic mass.

Other objects and advantages will appear which Figure 1 is a side elevation of the improved floor drain, a portion of a drain pipe'bein shown connected therewith,

Figure 2 is a vertical section showing the drain installed in a floor,

Figure 3 is a plan view of the drain, Figure 4 is a cross section taken on the As indicated in one of the brief statements of the objects of the invention, the principle of the latter is to allow for the seepage of moisture into a drain pipe from points outside of certain fittings which are used in the installation of the drain. This purpose may be accomplished in drains other than those used in floors, and the embodiment of the,

outstanding features in a floor drain is not to be regarded as a limitation.

In the drawings the body l is internally threaded at 2 at the lower end to receive the drain pipe 3. The end of the drain pipe abuts an annular shoulder 4 which prevents the closure of one or more seepage channels 5 which have outlets 6 in the circumferential face of the shoulder. Were the shoulder not provided there would be the grave possibil ity of the' body l being screwed down so far ppon the drain pipe'as to obstruct the out etsfip The channels 5 are formed in a second internally threaded bore 7, this at the other, side ofthe shoulder- 4, into'which bore the nipple 8 of an inlet or 'receiver'9 is screwed until it too abuts the annular shoulder 4.,

that far. Varying thicknesses of the plastic floor10 willdetermine the extent: towhich,

thenipple 8 is screwed-imbut the minimum I floor thickness would be that at which the nipple" is screwed down to the limit. r It's observed that the external threads on the nipple 8 extend throughout its length. I

This is -to"r'e'ceive the internallythreaded wrench head 11 of the'clamp l2. The clamp is preferably round but not necessarily so.

The'peripheral edge is curled down at 13 thus defining a seepage chamber 14 when the clamp is screwed down upon the flange 15 of'the drain body 1. Qpenings 16 intl1e-"curled edge 13"ad1nit any moisture to the chamber 14 that may percolate either through the floor 10' or around the fittings of the drain to a sheet 17 5 The nipple 8 isnot necessarily screwed down of'water-proofing material. The'peripheral edge'of thefiange 15 is curledupat 18, 'giving thefiangethe appearance of a "dish. The" ,water-proofing material, whether that be.

tarred paper, sheet lead or the like, laps into the dish far enough'to permit the clamp 12 to befscrewed thereupon to make a tight connection. v I g Inasmuch as tlie seepage channels 5 extend up to the "top'surface of the flange 15, it fol lows that they communicate with the chamber. 14. 3 Any moisturektliatmay percolate through the floor to the sheet-of water-proofing '17 will ultima'telyfind': its Way into the dish 18fchamber 14' and thechannels 5 whenceit will run off into the drain pipe'3.

A slotted cover 19 is secured to the receiver 9. This Ii'ifiush with" the floor 10. Upon installing the drain, the body 1 is fixedin position uponthe' drain pipe and the water back up. under it.

proofing sheet 17 laid over all adjoining supporting structure of the floor and made to lap over the flange 15. The nipple 8 with its clamp '12 is screwed in place in'the bore 7.

The clamp 12 is then screwed down until it firmly binds against the sheet 17 It is an outstanding purposeof the inventionto provide and utilize the clamp12 for; the securing of the sheet 17. This must be fixed in place around the drain, and it must be clamped down so hard that water cannotl The second major pur- I pose of the clamp 12 is to guard the seepage channels5.

These must not be obstructed. The plastic'material of whichthe floor is either composed or which enters the construction of thefioor willbe packed around the drain fittings as illustrated in Fig. 2. The dished clamp 12 will prevent the packing from' reaching the channels 5 and will establish the V in outside of the drain fittings.

chamber 14 intowhich the moisture will seep prior to entering the channels.

Fundamentally, therefore, the improved drain provides a through passage for the drain water, the former being represented bythe nipple 8 and drain pipe 3, which pas sa c has one or more external channels, that afiord communication thereof from points ]I claim 2- e 1. A drain comprising a hollow body With interiorly threaded end portions confronting av shoulder formed with an outlet communieating with a seepage channel formed in one of the threaded portions, a flange on the body having a curled up peripheral edge defining a dish into-which a sheet of water-proofing material is to be lapped, a drain receiver having a nipple with a full-length thread screwed upon on'eof the threaded ends .and defining a side closure forthe channel, and aclamp screwed upon the threads of the nipple, being peripherally curled down to bind upon said sheetof material and define a seepage chamber with which the channel has communication and having an opening for the admission of seepage to said chamber.
