DRAIN CONNECTION.

No. senses.

To all whom it may concern:

Be it known that I, EDWARD L. DAWES, a

citizen of the United States, and resident.

of New Brighton, in the count-y of Beaver and State of Pennsylvania, have invented a new and useful Improvement in Drain Gonnections, of which the following is a pecification.

My invention provides a new form of dra n connection. ior use on tubs, sinks and basins when it is desired to use a stopper or plug inconnection with the drain openmg to prevent escape of fluid.

Fittings which have heretofore been applied to the drain openings of tubs and the like have required a recess to be formed. in the surface of the tub surrounding the drain openin Practically all metal tubs, sinks, etc, 0% high grade are now covered on their inner surfaces With vitreous enamel and it has been found diificult to properly enamel tuhs which have a recess of the kind referred to. Moreover, when fittings of WelL known style are applied to tubs so termed it is found that the enamel is liable to creek or craze either atthe time of applying the fittings or subsequently for reasons unden stood by persons versed in the art. The portions of fittings heretofore used which appear Within the tul or sink have also been quite large and generally some kind of fastening device extends through the fitting and. is visible fromwithin the tut).

My invention provides a fitting which may he applied to gt tub bottom which is of ordinary uniform shape Without any abrupt angle or changes of direction: and without any recess surrounding the drain opening. The titling does not tend for any reason to ereelr craze the enamel. The tub or sink nro ided with a shallow depression sing with the main surface end surrounding the drain depression is of an easy not in the nature of a. recess. 7 in some cases to facilitate A tub COllStiillQi-(Bil as described may be perfectly enemeled with a minimum number of failures.

A fitting constructed in accordance with our. .lt .ls employ my invention is small and simple in con struction, consrstmg of few parts. it dis penses with an y exterior pregection on the tub bottom. The portion of the fitting visible Within the tub 18 of small diameter and has Specification oi Letters .Petent.

a pleasing and decorative appearance. No fastening device is visible within the tub. The fitting further provides for complete drainage of all the fluid in the vessel, there being no portion of the fluid contents which is trapped by any part of the tub bottom or fitting.

. The accompanying drawing. illustrates an exemplifying structure in which the invention is embodied, but it is to be understood that the invention is capable of embodiment in different formsQ In the drawing: Figure l is a vertical section through a tub'bottoi'n and fitting constructed in accordance with my invention. Fig. 2 is a View from within the tub of a fragment of a tub bottom with. the fitting inposition, the plug being removed.

Rggfierence cha actor I designates the/main inner bottom surface of a tub sink or basin. This surface is generally covered with vitreous enamel but to avoid complicating the drawing the enamel is omitted.

23 is the dreii'i opening passing through the tub bottom. it mayhcve a perfectly straight cylindrical wall, as shown. v

3 is a depression surrounding the drain opening and joining the main inner surface of the tub-with a gradual. curvature. The inner surface of the depression as shown immediately joins the drain opening without any intervening recess. The depression may son'ietim'es be omitted and in this case the substantially horizontal and that inner bottom surface of the tub contlnucs without change in shape directly to the edge of the tends below the outer surface of the tuh and an outwardly extending well 7, the bi n11 edge oi" which rests upon the in: surtace 2, oi the tub bottom close to the ill in opening. A nut 8 is screwed on the nipple below the lul: and servas to hold the flange firn'ily against the iiincr tuli surface. A gasket 9 is placed between the nut and the outer hotloin surface of the tub providing a fluid seal. One or more radial holes 10 are drilled or otherwise formed through the nipple so that the bottom of the hole or holes slightly below the adjoining inner bottom surface of the tub. One or more apertures '11 are ulso formed in the vertical wall 7 of the flange.

s A nipple 4 passes through the drain. open? Hit) A plug 12 shaped to fit the opening in'the nipple is provided. Theupper end of the bore of the nipple is generally-flared as shown and the plug is deep enough so that when it is in position it comes below and closes the holes 10.

The drain pipe 13 is connected with the nipple in any suitable way.

When the plug 12 is in position in the nipple the central opening through the nipple is closed and the inner ends of holes are also closed by the plug. No fluid can then escape from the tub through the drain opening. When the plug is pulled, however, the bulk of the water is discharged through the central opening in the nipple and at the same time water may pass through openings 11 which adjoin the tub surface and then through holes 10 and so out through the nipple and drain pipe. When water in the tub reaches the level of the upper surface of flange 6 it ceases to flow over the flange and through the upper part of the bore of .the nipple and the fluid then rem'a'ining in the .tub passes out through apertures 11 and holes 10.- These apertures and holes thus provide means for draining out every particle of water in the tub or sink. When the depression 3 is used it facilitates the collection of residual water around the drain opening and the discharge of this water through the opening and the depression also serves to bring the upper surface of the fitting within the tub down to approximately the level of the main bottom surface of the tub. By varyingthe depth of the depression the position of the upper surface of the fitting in relation to a tub bottom may be varied. When depression 3 is not provided water will drain out through the fitting more completely than is the case with fittings heretofore used of which I have knowledge.

The nipple may be provided with crossbars 15 for the usual purpose.
