DRAIN FITTING Filed April l5, 1943 Patented Feb. 12, 1946 Robert Dick, Mamaroneck, Y.,assi'gnoritoil?lelix n E. Wormser, secretary of Lead Industries Association, New York, N. Y.
Application April 15, 194s, seria-1 No. asairof c claims. 01. isz- 31%) 'This invention relates toa drain fitting.
An object of the invention resides in the provvision- `of `a drain fitting which is particularly adapted for use in connection with shower bath installations and wherein thel fitting is directly connected to Ythe waste pipe and is held vin posi-y tion principally by the Vconcrete base on which the tile surface is usually laid.
Another object of vthe invention `is to so construct the strainer of theitting rthat it may lbe emplaced without positive attachment and yet may easily 'loe removed. o
A still further object of the invention is to provide the fitting with pre-formed weepholes of such construction that they will be properly placed to permit the seepage of moisture into `the waste pipe regardless of the thickness of the concrete base lof the tile surface.
A still further object of the invention is the provision of atting which may be made from non-critical material such as hard lead, but it is to lne-understood that the breadth of the invention contemplates the use of other materials.
In the Vdrawing'z' f llii-gure 1 is a perspective View of theftting showing the same in its relationship to the usual lead pan that is `used lunder a yshower bath floor; and l Figure 2 lis a sectional View of the-'fitting showing its vassociatie-'n with the lead pan and its supports, the concreter-ill and the tile floor surface,
the section of the ttilngfbeing taken generally on line 2-2 of Figure 1.
pre-.form `theseholes because of the fact' that` there was no manner ofidetermining the extent to whichith'e cylinder would be screwed into the coupling due to'v the rpossible variation off the thicknessofthe 'concrete fill; o
Myinvention 'eliminates' the coupling and' pro' vides a fitting which Ais"v directly connected to the waste pipel and is provided withpre-formed uweep y, openings through which' the seepage may Occur.
Usually shower bath oors are provided vwithA y lead pans which `underlie the concrete ll which forms the base for the tile iioor surface.
Priorfto my invention the standard drain tting included an internally threaded coupling which was secure-d by soldering or otherwise to the waste pipe and to the lead pan, extending through a hole in the lead pan to the endvof the pipe which was located substantially below the pan.
An externally threaded cylinder which was embedded in the concrete ll was secured to the coupling and carried the usual strainer held in position byscrews. The interconnection of the coupling and the cylinder by screw threads permitted the cylinder to be screwed into the coupling to a greater or lesser degree, according to the thickness of the concrete fill.
After the cylinder had been positioned it was the practice for the installing Workman to drill holes through the cylinder to permit seepage into the waste pipe. It was not the practice to A`Referringnow to thedrawing thelleadpan is indicated by the reference Anumeral I;. Thslpan rests upon the usual'V ood supports 2, between which and the pan isv aV liner 3*.
The wastepipe 4 extends to and is directly connected with thejpan I sothat the waste pipe registers *withv the opening 'in the'rpan Vv'Ihis securement ,may be by any conventional means such assoldering'; o v
y The iitting 6 is `sulcstantially circular in cross section Aand Vits outer `wall 'l Sis tapered toward' the open 'end' 8 that .engages with the waste pipe 4 so that the ttinginayv be forced into the waste pipe topro'du'ce a snug i'it, with the result that the fitting and the waste pipe will be heldin a proper association by they developed friction. This securement of the lit'tingA to the waste pipe may befaugmented, lif desired, by `soldering `at '9. A Of course when the tting and pipe arefboth made of lead Athe Vmalleability .of the lead will lend itself jto va tight lit. Moreover 'the 'tapering Y ofthe outer wall of the fitting permits the fitting to be forced intothe drain pipe to different eX- tents so that the fitting may be adapted to concrete-fills of 4various thicknesses.
VAdjacent"the upper-end of the ntting a plurality of lugs I-llare located and are adapted to ibe embedded in'the concrete fill II-on which the tile door surface I2I is supported, so that the concrete fill will prevent any movement of the fitting after it has been installed and the concrete emplaced.
The upper end of the fitting is provided with the usual nange I3 and with a removable strainer 'IL The outer wall I5 of the strainer is tapered downwardly and is adapted to frictionally engage an inclined wall I6 into which the strainer fits. 'I'hus a frictional engagement will be developed which will maintain the strainer in position. However, to prevent the strainer from becoming jammed in the opening the shoulder I1 on the inner wall of the fitting will engage with the lower end I8 of the strainer and thus limit the downward movement of the strainer beyond the danger point.
The fitting is provided with a plurality of weep- Of course at times the concrete fill Il will begreater in thickness than at other times and consequently the degree to which the fitting is forced into the waste pipe will vary withvthe thickness of the concrete. After the fitting has been positioned the concrete is then poured and It is of course to be understood that this invention isnot limited to the use of non-critical materials or to hard lead but the construction may be embodied in various other materials.
What I claim is:
l. A waste pipe fitting substantially circular in cross section and having an outer Wall tapered toward an open end, a strainer in said fitting at the opposite end, a lug extending from the outer wall of the fitting adjacent the strainer,
, `and a longitudinal slot in the fitting establish- Y ing communication between the inside and the outside of the fitting.
2. A construction including a pan, a lead Waste pipe connected with said pan, a layer of floor fmaterial on said pan, a waste pipe fitting exthe tile floor surface applied, with the result that the fitting will be securely held in position. Y g It may ai; times be desirable to protect the weephole slots I9 against becoming filled with the concrete after the concrete is poured. This may be done by wrapping a piece of material, such as paper, around the outer Wall of the fitting to cover the slots. This will prevent the flowing of the concrete into the slots and yet will permit the seepage of the water through the slots even before the material becomes disintegrated, which of course it will do due to the reaction that takes place as the concrete is poured. The application of such a strip of material, however, is not always necessary. Its necessity depends to a great extent upon the character of the concrete that is poured. It will be realized that by making the Weephole slots relatively long they may be pre-formed and therefore will functlon regardless ofthe distance, from a practical point of view, to which the fitting is forced into the waste pipe. In other words, if the tting is forced into the waste pipeV to such an extent that part of each of the slots will be thereby covered, the remaining portions of the slots will be suflicient to permit the seepage to pass into the waste pipe.
`Thus it will be seen that I have provided a iitting of the character above set forth which will eliminate the coupling between the fitting'and the waste pipe, which will securely be held in place by the concrete fill and which will adapt itself in its pre-formed state to application to waste .pipes regardless of the variation in thickness of the concrete fill.
Moreover I have produced a fitting which may be made entirely of non-'critical material such as hard lead, and yet which is so constructed that it will properly function, and so that the strainer may be removed at will for cleaning purposes.
tending into and having frictional engagement with said pipe, and a lug extending from the fittlngand embedded in said floor material.
3. A construction including a pan, a lead waste pipe connected with said pan, a layer of fioor material on said pan, a waste pipe fitting extending into and having frictional engagement with said pipe, and a lug extending from the fitting and embedded in said iioor material,
the said fitting having a slot arranged longi-v tudinally ltherein and establishing communication between its outside `and inside whereby seepage is permitted into the Waste pipe.
4. A construction including a pan, a lead waste pipe connected with said pan, a layer of floor material on said pan, a waste pipe fitting extending into and having frictional engagement with said pipe, a lug extending from the fitting and embedded in saidiioor material, and a removable strainer in said fitting.
5. A construction including a pan, a lead waste pipe connected therewith, a hard lead fitting substantially circular in cross section and having an outer wall `tapered toward the drain pipe, said fitting being telescoped into the drain pipe and being held frictionally therein, a lug extending from the outer Wall of the fitting, the fitting having a slot extending longitudinally thereof and establishing communication between the inside and outside thereof, and a floor material surrounding said fitting and embedding said lug.
6. A construction including a pan, a lead waste pipe connected therewith, a hard lead fitting substantially circular in cross section and having an outer wall tapered toward the drain pipe,
said iitting being held frictionally therein, a lugl extending from the outer wall of the fitting, and a floor material surrounding said fitting and embedding said lug.
