Marchand,` Jr., Maywood, Ill., assignors to Crane Co., Chicago, Ill., a corporation of Illinois Original application June 17, 1938, Serial No. 214,200. Divided and this application October 14, 1939, Serial No. 299,516

4 Claims. (Cl. 4-287) More particularly, our invention relates to a more simple and economical sink strainer and stopper combination than heretofore available for the purpose set forth, in which the latter member is preferably embodied in basket or tubular form with one end perforated for straining purposes and in which a suitable plug or stopper member carried by the strainer or basket is reciprocably movable therewithin so as to serve as a valve shut-offA enabling the filling of the basin of the sink with water, if desired. This application is a division of our original application Serial No. 214,260 led June 17, 1938.

Sink stra-mers of a previous type have been available in which the valve has been removable as an integral part of the strainer and in which the stopper member mounted in the strainer has been reciprocably movable upon similar movement by the handle, but to our knowledge no one has employed a construction in which upon the combination of reciprocating and pivotal movement of the stopper handle the latter member is so actuated to be positioned close to the top or rim of the basket strainer whether the valve is in open or closed position, thus clearly avoiding the usual deposits within the strainer.

Another important advantage lies in providing toggle action in a jointed handle whereby the plug or closure member may be suitably locked.

Another advantage lies handle form of construction in which the latter may be actuated with great convenience.

A further object lies in providing for a strainer and a valve closure member in which the latter member may be removed either individually for ready replacement or inspection or while assembled with the basket strainer, the removability being facilitated by the disengagement of the valve handle allowing for the strainer t-o be lifted without disturbing the positioning of the valve proper.

Other advantages of the construction will become more readily apparent in connection with a review of the patent drawing as described in the following figures:

Fig. l is a sectional assembly view of an embodiment of our invention showing the preferred embodiment of the construction in which a jointed or toggle mounted lever handle is used to lock or hold the plug or closure member in an open position upon the strainer.

Fig. 2 is a fragmentary plan View of the same construction.

Fig. 3 is a view similar to Fig. 1 except that in providing a T the plug or stopper is shown in the closed position.

Similar reference characters refer to like parts throughout the various views.

Referring to Fig.` 1, the numeral I refers to a sink' structure provided with the usual enamel coating. 2 and having a drain opening 3 within which a conventional spud member 4 is. applied, having one portion threaded as at 5, the lower portion of thesink at 6 having an abutting surface against which the gasket member 'i is positioned. A locking nutl 8 is threadedly mounted upon the threads 5 of the spud member 4 in o-rder to hold the latter in position within the sink drain opening 3 `and also to make a` watertight joint preventing leakage past the periphery of the/Spud. member within the sink opening proper. The lower porti-on of the spud, as at 9, is preferably tapered and provided at its extreme lower portion with threads II by means of which the usual connection is made to a pipe and trap (not shown). A conventional-spider I2-'is used therein to prevent relatively large particles from dropping through/and into the sink discharge trap (not shown) Resting upon the peripheral shoulder I3 therewithin, a basket type of strainer I4 is mounted, the sides of which may be made solid, as indicated, or perforated, and the lower portion, as at I5, is preferably perforated to serve as a strainer. The strainer I4 at its center portion is provided with a hub I6 within which a valve member and jointed or pivotal lever I'I are reciprocably journaled, the handle preferably being of cylindrical form and having a T connection I8 at its upper end and pivote-ily attached, as at I9, to a complementary cylindrical form 2| journaled snugly within the hub I6 and preferably an integral part of the valve or stopper member 22, having a nished seat portion 23 for engagement with a similar surface or seat 24 upon the spud 4. 'Ihus it will be apparent that by simply placing the lever II in a vertical position the stop end 25 may then be moved interiorly within the bearing of the hub I6 so that the lever I'I is then in axial alignment with the lower portion 2I. This will enable the entire valve structure and handle to be dropped by its own weight against the seat 24 and thus close the drain opening when desired.

It will be further apparent that upon gripping the T extension IS, the valve 22 may be lifted from the seat 24 and, if desired, the entire basket strainer I4 may be removed simultaneously with the closure member 22, or if it is desired to drain the water, then the handle may simply be lifted` within the strainer proper, and if desired fur" ther, the T connection I8 may be dispensed. .a with entirely, in which case the basket type strainer may be slipped over' the cylindric:al por tion of the handle l1 without disturbing' 'the positioning of the valve 22. Obviously, of course,

if it is desired to retain the T'connectin 48,z the pin I9 may readily be made removable for.

the purpose of disjointing the handle thereby providing for the independent removal ofthe basket type strainer. y

Having thus described our invention what we claim and desire to secure by Letters Patent is:

1. In a combined sink strainer and stopper arrangement, a tubular member secured within the drain opening of a sink or-the like, a stopper serving asa shut-oir for `the said drain opening and seating in the lower end of thesaid tubular member, a 4substantially cylindrically formed strainer adapted to be positioned loosely within the said tubular member, Van actuating handle for the said stopper member, guide means for the stopper projecting upwardly within the strainer, said handle being pivotally movable upon van upper portion of the said guide means, whereby upon pivotable movement of the said handle to a position in substantial axial alignment with said guide means the said stopper member is rendered reciprocably movable relative to the Isaid strainer.

2. The combination of a sink strainer and stopper including a hollow Spud member and a cupped strainer adapted to be positioned within the drain opening of a sink or the like, ya reciprocably o-perable plug for the saiddrain opening, the said hollow spud member providing a seat for the said plug, a demountably attached pivotable opterating handle for the said plug, whereby upon disengagement of the said handle from its pivotable attachment with the said plug the said strainer may be. removed without displacement of the vsaid .plug from the said seat'.

3. In a combined sink strainer and plug arrangement, a hollow spud member secured within the drain opening of a sink or the like and providing a seat for the said plug, a cupped strainer rangement, a hollow spud member secured within the drain opening of a sink o-r the like and providing a seat for the said plug, a cupped strainer adapted to be removably positioned within the said spud member, the said plug being positioned below and outside of the said strainer and being reciprocably operable by a pivotably movable handle, the latter when in its vertical position being extendible through a suitable aperture communicating with the cupped portion of the said strainer, the said plug having an extended portion journaled within the aperture of the said strainer, the said extended portion forming' a substantially unbroken guide means within the Iaperture and between the said handle and the said plug when the latter member is moved from open `to closed position and vice versa.
