7 Claims. (Cl. 4-287) This invention relates to waste fittings for connecting the drain outlets of a sink, washing tank, or the like, to a waste pipe, and more particularly to fittings of the type provided with a strainer and a plug or` valve below the strainer forl closing the outlet, together with means for retaining the valve in an open position to pedmit drainage. .d

`The present invention has for an object to x 10 provide guiding means above and lbelow the valve which constrains the valve to axial and rotative movements, together with valve-supporting means adapted to hold the valve in an elevated open position in one angular position of the valve and l5 adapted to permit the valve to close when it is turned. V

A further object is to provide a valve-supporting means including a cam by which the valve maybe elevated to open position by a turning movement thereof.

With the above and other objects in view the invention may be said. to comprise the device as illustrated inthe accompanying drawing herein after described and particularly set forth in the appended claims, together with. such variations and modliications thereof as will be apparent to those skilled inthe lart to whch the invention appertains. Reference should be had to the accompanying drawing forming a part of this speclcation, in

which:

Figure l is an axial vertical section showing the tting secured in the outlet opening of a sink and the valve in closed position; l

Fig. 2 is an amal section through the fitting showing the valve inopen position;

Fig. 3 is a top plan view of the iitting;

Fig, 4 is a perspective view of the valve and valve stem;

40 Fig. 5 ls a perspective view of the valve-sup- Porting and guiding member.

Referring to the accompanying drawing, a' tubular coupling member I is provided with an outwardly projecting peripheral ange 2 at.its

upper end. The coupling member is mountedin thesdrain opening of a sink or other receptacle and the flange 2 overlies the bottom wall 3 of the sink at the margin of the opening.v The coupling member I is exteriorly threaded to receive a clamping nut l which cooperates with the flange to clamp the bottom wall of the margin of the drain opening. The coupling member I has a reduced lower end 5 which is threaded for attachment to a drain pipe 6. At the upper end of the reduced portion 5 the coupling memsink at the ber I is provided with an'internal valve seat 1 which-receives a plug or valve 8 which, when resting on the seat, cuts off the iiow of water through the iitting. The valve 8 has a stem 9 which is secured to the valve axially thereof and which 5 projects upwardly from the top face of the valve and downwardly from the bottom face thereof. The upper end of the valve stem 9 is provided with a suitable knob I0 which may-be conveniently grasped to lift or turn the valve. In the upper l0 portion of the coupling member I there ls mounted a cup shaped strainer Il. The strainer ii has .an outwardly projecting peripheral flange I2 at its top which rests upon a shoulder- I3 within the upper portion of the coupling member E. The 16 strainer I I provides 'a guide above the valve 8 for the valve stem 9, having a central opening i4 in which the valve stem iits and in which the valve stem is slidable and rotatable.

In the reduced portion of the coupling mem- 'gu ber'i below the valve seat there is mounted a supporting member I5 which is provided with a central opening I6 in which the downwardly projecting portion of the valve stem 9 has a sliding and rotating fit. The valve stem 9 is guided above 25 the valve 8 by the strainer II and below the valve 8 by .the supporting member I5 so that the valve 8 and stem 9 are constrained to axial and rotative movements. On the opposite sides of the central opening I6 the supporting member I5 car- 3o vries upstanding valve-supporting members I1 which serve to support the valve in open position. The supporting members I5 is preferably inthe form lof a disk secured within the lower .end portion 5 of coupling member 5 and the sup- 35 porting members I1 are preferably in the form of flanges struck up from the body of the disk I5. The flanges I1 are preferably provided with oppositely inclined end edges Il, and may be substantially semicircular in form. At the tops 40 thereof the flanges I1 are preferably provided with flattened or slightlyl recessed portions I9. The flanges I1 cooperate with an elongated cam member 20 attached to the valve and which may be formed integrally with the valve. The cam 45 member 20 extends across the center of the underside of the valve, projects downwardly, and preferably tapers toward each end. The' cam member 20 is preferably provided with downwardly tapering side faces 2l which are engageable with the 50' inclined end edges I8 of the flanges I1 so that,

' when a turning movement is imparted to the valve, the ends of the projecting cam members 20 readily ride up the inclined ends IB of the flanges I1 and thereby lift the valve off its seat. To per- 55 mit easy turning of the valve to open the same, the flanges II are preferably disposed at an inclination and diverge upwardly. The shallow recesses I9 in the tops of the flanges I1 receive end portions of the cam member 20 when the valve is turned through an angle of 90 from the closed position.

The bearings for the valve stem above and below the valve prevent tilting of the valve and stem so that engagement of the inclined side faces 2I of the cam member 2U with the inclined end edges I8 of the iianges I1 imparts an axial upward movement to the valve to raise it from 4 its seat. After the valve has been turned through 90 the end portions of the cam member 20 drop into the recesses I9 and the valve is retained in open position. Only a small angular movement is required to move the end portions of the cam member 20 out of engagement with the recesses I9 and into engagement with the inclined end portions I8 of the anges'l'l.

.It will be readily apparent that the valve may be opened by turning it in either direction and that when the valve is supported in open positionit may be closed by slight turning movement in either direction, the valve dropping to closed position by gravity as soon as the end portion of the cam member 20 engages with the inclined end portions I8 of the supporting anges I1.'

The bottom face of the valve 'I is preferably provided with recesses 22 on opposite sides of the cam member 20 which are adapted to receive the upper portions of the flanges II when the valve 8 is in closed position, reducing the clearance required between the valve seat and the supporting member I5 so that the member I 5 may be mounted quite close to the valve seat 1.

The valve 8, stem 9 and strainer I I are removable as a unit from the coupling member I when it is desired to clean the strainer and will readily drop into place when the lower end of the stem 9 is inserted into the central opening I6 of the supporting disk I 5.v

Although a single embodiment of the invention has been herein shown and described, it will be understood that modifications of the invention may be resorted to without departing from the spirit thereof or the scope of the appended claims.
