2 Claims.

A prime object of the present invention is to provide a novel and improved drain spillway that permits the desired mixing of hot and cold water ina basin which has separate hot and cold water faucets without mixing means.

Another object is to provide a drain spillway which shall embody novel and improved features of construction whereby to 'retain in the basin a body of water of predetermined depth for washing, rinsing and draining purposes and at the same time allow the water to'flow continuously intothe'basin from the supply faucet or faucets and away therefrom through the usual drain pipe."

'Still another object is to provide a device of this kind that shall include a novel and improved construction and combination of a tubular body having a fully open upper end and astrainer' to permit suds, lather, grease or the like to drain away freely but to prevent articles from falling into or being carried by the water into the drain p1pe.- 7

Further objects are to provide a device of this to provide the device with a tubular body having a fully open top end and a base having suction faces for engagement with the bottom of the basin for firmly holding the device detachably in posltion on the bottom surfaces of basins having various types "of drain openings including those having valves that rise'upwardly therefrom.

Other objects of the present invention are to provide a' drain spillway that is compact, simple in construction, economical to manufacture,'portable. easily carried'i'n a traveling bag for use in a hotel, easily mounted in the ordinary type basin and easily removed therefrom.

The invention will be better understood from the description thereof to follow taken in connection with the accompanying drawing in which- Figure 1 is a part elevational and part sectional view of a basin showin a drain spillway embodying my invention in position over the drain pipe.

Figure 2 is an enlarged sectional view of the drain spillway.

Figure 3 is a top plan view thereof.

Referring to Figure 1, the improved drain spillway I is shown installed in a basin or sink 2 of ordinary construction having a drain opening 3 adjacent its side wall 4 and communicating with one end of a drain pipe 5 which receives and carries away the water drained from the basin.

Only a single water'faucet 6' positioned above the drain opening is shown but the invention contemplates the use of at least two separate faucets,

one for hot and the'other for cold water.

The spillway is a single unit formed of flexible portion extends below the base forming an annu-'-" l'ar flange 9. The outer wall of the tubular portion' tapers slightly downwardly and outwardly. The base is formed with a "downwardly extending margin or edge portion 10 extending therearound and spaced inwardly therefrom is another semi-circular downwardly extending flange portion H which may be slightly wider and shallower than the margin Ill. The margin l0 and the flange portion ll together with one half:

of the circular flange'Sof the tubular body portion provide a space or annular suction cup l2 whose bottom comprises a substantially annular suction face I3 on the base which tapers to a narrow point between the circular flange and the margin W as indicated at 14. The semi-circular flange and the other one-half of the annular flange 9 provide a' spacejor suction cup [5 Whose bottom comprises a crescent-shaped suction face [6 on the base. The annular flange 9, margin or edge portion [0 and flange H are sufficiently surface.

About midway its length, the tubular body portion is formed with a strainer comprising a transverse wall I! integral with the side wall of said tubular body portion. The wall is provided with a plurality of slots [8 adjacent the side wall and with a plurality of various sized perforations or holes l9 between said slots. This transverse wall may be slightly dome-shaped to facilitate drainage of the water therefrom. It makes the tubular body portion more rigid preventing it from collapsing. The depth of the tubular body portion determines the depth of the body of water retained in the basin and it may be made as high as desired within the confines of the depth of the basin.

In use when it is desired to install the spillway in the basin, the spillway is fitted over the drain opening 3 with the flange portion 9 of the tubular body portion resting on the upper peripheral edge of the opening as indicated at 20, and with the margin I and flange I I resting on the bottom of the basin at points spaced outwardly of said opening. Downward pressure is then applied to the tubular body portion thereby forcing the annular flange portion 9 into intimate contact with the upper edge of the opening and forming a seal thereat, and at the same .time forcing the margin 0 and'flange it together with the suction faces l3 and I6 into intimate close contact with the bottom of the basin and creating a vacu-. um between said faces and the bottom of the basin. The suction action between the suction face l3 and the bottom of the basin is sufiicient to hold the spillway firmly in position but this suction action is augmented by the suction between the suction face IE and the bottom. Thus a double seal is produced which firmly holds the spillway in operative position.

. The water from the faucet or faucets 6 is then allowed to flow freely into the basin and is retained'. therein until the depth thereof reaches the top of the spillway as indicated by'the'dotdash line 2| of Figure 1 which is sufficient for ordinary washing and rinsing purposes. Thereaftenthe. water may continue to flow into the basin from the faucet or faucets as long as desired and it will be discharged from the basin thioughthe spillway as fast as it is delivered thereto while retaining the desired depth of water in the basin. The water in the basin can readily be. tempered by permitting the water from the hot and cold water faucets to 'mix'and by allow ing. the too hot or'too cold mixed-water to overflow into the spillway until the proper temperature'is reached. Anything'floating on the surface of. the water in' the basin such as suds. lather,

grease or the like may be readily floated over the spillway into and throughthe openings and slots inthes'trainer into the drain pipe, 'or'toothpaste or mouthwash may be, deposited. directly through the fully open top'end'. of the tubular body. This eliminates. the necessity of emptying the; entire contents. of the basin. down the drain pipe and thus is more economical and time saving. Furthermore, the location of the strainer intermedi-' ate the length or a. substantial distance below'the rep or the tubular body-portion, provides a water. head above the strainer to continuously flush or carry off suds, scum, etcthrough the strainer and also permits a drain. valve to rise upwardly freely from'the drain opening. Solid objects are prevented. from passing into the drain pipe by the. solid, portions of. the transve'rse'wall. l'l.

When it is desired to remove the spillway, the

tubular body portion serves as a handle whereby the base portion can be pulled outwardly and twisted to deform the outer margin I0 and flange H slightly in order to destroy the vacuum areas and permit the device to be removed.

The spillway is easily transported and may be readily installed in any ordinary type of basin without altering either the spillway or the basin.

vChanges in details might ;.be;re sorted to without departing from the spirit or principle of the invention.

What I claim is:

1. A drain spillway for a basin that has a drain 1' opening in the bottom thereof, comprising a thin The following references are of record in substantially fiat flexible base having a continuous annular downwardly projectin flange extending throughout its edges, a tubular portion integral and eccentric with respect to said base and having its upper end portion fully open and projecting upwardlyfrom said base and having its. lower end projecting downwardly from-said base] beyond the plane of said marginal flange within and spaced from said marginal. flange; whereby said'spillway may beset with both said marginal flange and. said lowerend of the'tubula'r portion in contact with said, bottom of the.

basin and with said lowerend of the tubular portion in closely encirclingrelation to'saiddrainj opening evenjwhen said openingv i close to. a side wall of the basin."

2.. A drain spillway for basins s; uefinedin;

c im 1, with the addition or an integral wall ex? tending across theirft'erior of said "tubular body' portion a substantial distance below the upper end. thereof. andfa. "substantial distancev above the. lower end thereof; said wall being. formed. with;
