SINK STRAINER AND STOPPER AND,THE LIKE Original Filed June 17, 1938 Patented Apr. l, 1941 UNITED STATES SINK STRAINER AND STOPPER AND THE LIKE Roy H. Zinkil, Oak Park, and Eugene W. 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 July 3, 1939, Serial No. 282,716

2 Claims.

, Our invention relates to a more simple and economical sink strainer and stopper combination than has heretofore been `:available for the purpose set forth, in which the latter member is preferably embodied in a. 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 4basket is reciprocably movable therewithin so as lto serve as a shut-off valve enabling the filling of the basin of the sink with water, if desired. This application is a division of our copending application Serial No. 214,200, led June 17, 1938.

Sink strainers 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 pivotal movement, the stopper handle is so actuated as to be positioned close to the top or rim of the basket strainer whether the valve is in the open or closed position, thus clearly avoiding the usual deposits within the strainer.

Another object of our invention is to provide a slot and crank mechanism fulcruming lon an enclosing centerpiece of the strainer.

Other objects of the construction will become more readily apparent upon proceeding with the description in connection with the drawing, in which Fig. 1 isa sectional assembly view of a preferred embodiment `of our invention showing the construc-tion of Ithe slot and crank mechanism and showing the stopper in the raised or flow permitting position.

Fig. 2 is an external plan View.

Fig. 3 is a sectional assembly view taken at right angles to Fig. 1.

Like numerals refer to like parts throughout the various views of the drawing.

Referring to Figs. 1 and 2, 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 the sink at 6 having an abutting surface against which the gasket member 1 is positioned. A locking nut 8 is threadedly mounted upon the threads of the spud member 4 in order to hold .the latter in position within the sink drain opening 3 .and also to make a water-tight joint preventing leakage past the periphery of the spud member within the sink opening proper. The

lower portion of the spud, as at 9, is preferably reduced and provided at its extreme lower end 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 is provided with .a central hollow boss I6 within which the guide member or extension I'I of the valve closure member I8 is reciprocably journaled. The g-uide member I'I and the stopper member I 3 yare preferably deta-chably secured together, the latter member having a finished seat portion I9 for engagement, as shown in Fig. 3, with a similarsurf-ace or seat 2I upon the spud 4. The guide member I'I at its upper portion has a slotted part 22, as indicated at 23. A handle 24 is journaled within the central hollow boss as at 25 (Fig. 3), the handle 24 being provided with an offset portion 26 whereby, upon rotation of the handle 24 in an arcuate manner. the offset portion moves within the slot 23 so as to raise and lower the valve stopper I8. It will be noted that the handle proper is mounted compl-etely within the hollow boss. The advantage of this construction lies in having a more sturdy arrangement insofar as durability is concerned, and also enables quick removal for purpose of repair and inspection by means of the threaded cap 2'I.

One embodiment of the invention is herein shown and described, lbut itis not desired to limit the invention to the particular embodiment shown. Therefore, we desire to be limited only to the extent of the appended claims.

We claim:

1. In a combined sink strainer and plug arrangement, a hollow member secured within the drain opening of a sink or .the like, :a plug serving as a :shut-olf for the said drain opening and seating in the lower end of the said hollow member, an upwardly concave strainer member removably positioned above the said plug within the sai-d hollow member, a plug actuating handle pivotably mounted upon an upwardly projecting portion of the said strainer and extending through the said projecting portion, the said plug having extensions cooperating with the end portions of the said handle, whereby pivotal movement of the said handle causes the said plug member to aol; against a seating surface in the said hollow member.

2. The combination of a sink strainer and stopper including a tubular member Within the ydrain opening of a sink or the like, a stopper f serving as a shut-off for the said drain opening and seating Within the said tubular member, a

Substantially cup-shaped strainer adapted to be v positioned within the said :tubular member, a pivotally mounted handle for the said stopper member, *the said strainer having centrally positioned journaling means for the said handle, the said stopper having lan extension cooperating with the said handle Within the said journaling means.
