In the accompanying drauungs, Fig. 11s a sectional view of the device attached to'the wall of a vessel, and Fig. 2 is a frontview of the overflow and controlling parts of the device. Fig. 3 is an elevation ofthe clamping ring for supporting the overflow plate. Fig. l is a perspective view .of the valve.

:Fig. 5 is a horizontal section ofgthe valve within the T-fitting. Fig. 6 is enenlarged sectional view on line '66 of Fig. I? .of'the overflow portions and controllinghandle of the device. Fig. 7 is a horizontal section of the same parts on line-77 of ll 8 is a sectional view-on line ;8 8-of Fig. 7, showing the spring-pressed. detent for locking the controlling handle. Fig. 9 is a sectional view corresponding tofFig: 1, of a modified form of the inventioman-djFig. 10 is a front. sectional view on line 10-1O of Fig. 9. Fig. 11 is a sectional view horizontally of the elbow on line 1111 of Fig. 9. Fig. 12 is a sectional view on line 1212 of Fig. 10, of the lever and detent device. Fig. 13 is a sectional view horizontally through the overflow and drain fitting and the valve therein, on line 1813 of Fig. 9.

The invention involves the use of an overflow head or elbow A which is adapted to be clamped against the outer wall by a basin, tub, or other vessel B, having an overflow opening2 therein. Such vessels are also pro vided with a drain opening in the bottom thereof (not shown) to which a drain pipe C is connected, all as known to those skilled in the art. Pipe C is coupled to a side branch 3 of a pipe fitting D. This fitting has vertical branches 4 and 5, respectively, to which an overflow pipe 6 and discharge pipe 7, are adjustably coupled by gaskets and nuts 8 and 9 respectively. Overflow pipe 6 is connected with the bottom end of 1929. Serial No. 365,658.

overflow elbow A, and the elbow itself is clamped to the wall of vessel B by a pair of screws 10 which pass through a clamping ring or equivalent member E placed against the front face of the vessel wall opposite overflow opening '2. Screws 10 con- 'nect witha pair of internal lugs 11 and 12 respectively cast integral with elbow A, and lug 12 on this elbow includes a cylindrical bearing portion l-fl which extends forwardly into opening 2. A sealing gasket 15 is usually interposed between elbow A and the wall of vessel B.

A perforated cover or strainer plate F is fastened to a bridge or spanning portion 16 of clamping member E, a central screw 17 being provided for that purpose. The strainer plate may therefore be attached and replaced without disconnecting or releasing the overflow elbow or disconnecting parts clamped upon the wall of the vessel, including the controlling handle G which is pivotally mounted upon the cylindrical projec tion 14: extending forwardly from lug 12 on elbow A. 1

Handle G is adapted to be rotated approximately 90 and extends through a slot 18 within a border edge or annular flange 19 of strainer plate F,.see Fig. 6. Handle G is of angular formation or provided with an offset or arm 20 having an opening or open bearing 21 adapted tosleeveiover cylindrical projection ll 'whi'ch is located near one side and voif-center of the mouth of elboivA. The handle or controlling lever G is also provided with an operating extension 22 which is projected at an angle into elbow A where coupling member .23 is adapted to be connectedtherewith directly in line with overflow pipe 6.1 p

A rod or link24 is screwed or otherwise attached to member 23', and the lower extremity of the said rod or link is formed with an eye 25 to provide a'suspensory connection for a valve H movable vertically within the T- seat against the border edges of drain opening 26 to close the same when the valve is lowered within fitting D, and an inclined rib 28 forming an integral part of fitting D directly opposite drain opening 26 serves to guide and press the val e by its own weight against the valve seat when the valve is lowered within the fitting. To promote that purpose valve H is formed with a channeled head 29 to embrace and engage the inclined guide rib 28.

As constructed valve H is of smaller dimen- 7 sions or cross section than the chambers within fitting D, thereby permitting the overflow waste to pass to discharge pipe 7 when the valve is either raised or lowered within fitting D.

Seating of valve H is by gravity, and therefore when the controlling lever or handle G is turned on its pivot to the dotted position shown in Fig. 6 to raise and open valve H in respect to drain opening 26, it is desirable at times to lock the lever in that shifted position. This is accomplished by a springpressed plunger or detent 30 carried by lever G, and this plunger may extend radially of the lever opposite the rounded surface of lug 12 on elbow A. Lug 12 may be provided with a depression or socket 31 to receive the plunger when the handle is turned to its limit of movement as indicated by the dotted lines in Fig. 6. The structural details of the pivot lug and the spring-pressed detent are shown more clearly in full lines in Fig. 8.

Figs. 9 to 13 inclusive, represent a modified structure. Thus, the T-fitting D is constructed to seat a valve H having a circular sealing face of the same curvature as the inner wall of the fitting. This valve is also formed with a channeled portion 29 to embrace an inclined rib 28 within fitting D. The valve is connected by a link or rod 24 to a crank extension 22 on a lever G, having a spring-pressed plunger extending forwardly where it is adapted to press against the inner face of a clamping bar E. Lever G is supported by a pivot lug 14' at one side of the mouth of the elbow, and the lever is locked or held at the limits of its arc movement when plunger 80 engages depressions or notches 31 in bar E. Otherwise, this structure is similarto the one shown in Figs. 1 to 8, inclusive.

What I claim, is:

1. In an overflow and drain fitting for a bath tub, lavatory basin, sink, or like vessel, an overflow elbow having an integral pivot lug within its mouth, an overflow and drain fitting connected with said elbow having a valve therein, and means pivotally supported by said lug for operating said valve.

2. In an overflow and drain fitting for a bathtub, lavatory basin, sink, or like vessel, an overflow elbow having a pair of attachment lugs internally at opposite sides thereof,

a valve controlling lever pivotally supported upon one of said lugs, and an overflow and drain fitting connected to said elbow having a valve therein connected to said lever.

3. In an overflow and drain fitting for a bath tub, lavatory basin, sink, or like vessel, an overflow elbow, a clamping member for said elbow, clamping screws for said member connected interiorly with said elbow at opposite sides thereof, a lever fulcrumed at one side of said elbow at its point of connection with one of said clamping screws, and an overflow and drain fitting having a valve therein operably connected to said lever.

4. In an overflow and drain fitting for a bath tub, lavatory basin, sink, or like vessel, an overflow elbow, an overflow and drain fitting connected to said elbow, a valve within said fitting, and operating means for said valve, including a pivoted lever and a springpressed detent to lock the lever and valve in open position.

5. In an overflow and drain fitting for a bath tub, lavatory basin, sink, or like vessel, an overflow elbow and a clamping member therefor, a lever pivotally supported opposite said clamping member, a detent associated with said lever to hold the same in an open position, an overflow and drain fitting connected to said elbow, and avalve within said fitting having lift connection with said lever.

6. In an overflow and drain fitting for a bath tub, lavatory basin, sink, or like vessel, an overflow elbow having a pair of attachment lugs, a clamping member and screws adapted to connectwith said lugs, a cover plate attached to saidv clamping member, a y;

lever pivotally supported at one side of said elbow where connected to said clamping member, a spring-pressed detent for holding said lever in an open position, and an overflow and drain fitting containing a valve operably connected to said lever.

In testimony whereof I affix my signature.

CHARLES F. SCHULTIS.
