Hiertz, Bridgeport, Conn., assignor to BridgeportBrass Company, Bridgeport, Conn., a corporation of Connecticut Application October 1, 1943. Serial No. 52,194

This invention relates to a removable sink strainer orperforated container for catching crumbs, refuse, or the like in drain openings, ombined with a means of preventing the liquid from draining when so desired. In sink strainers now in use it is necessary to locate the perforated strainer-stopper assembly in the drain opening by the use of aligning slots, lugs, or projections, and time i wasted in trial and error to determine the correct positions, of i Objects and features of this invention parts. are to provide a strainer or perforated containerstopper assembly which is operative in any position in. the drain opening and which does not require the. usual finding and locating devices necessary with strainer now commonly in use. it is only necessary to place the perforated strainer and stopper assembly in a tubular body or. member located in the drain opening.v In

this position the strainer is, seated and the stopper is open or oii the valve seat, of the tu- By. mply closing the valve seatof the. tubular body and preventing drainage. When drainag'eis desired, a simple pull upward on the center post or stud raises the stopper from the valve seat in ,theftubular body thereby draining the contents of the sink or the like, No angular orientation of the strainer relative to the axis of the tubular body is required.

Another object of the invention is to provide a simple effective device for the intended purposes.

Other objects, novel features and advantages of this invention will become apparent from the following specification and accompanying drawings, wherein:

Fig. 1 is a cross sectional View of the entire strainer-stopper assembly positioned in the tubular body and showing the stopper in the closed or non-draining position; v

Fig. 2 is a plan view of the same on a reduced s a v Fig. 3 is a section taken along line 3- -3 of Fig. 1 and viewed in the direction of the arrows;

Fig. 4 is a section taken along line 44 of Fig. 1, also viewed in the direction of the arrows; and

Fig.5 is a cross section similar to Fig. 1 showing the stopper in the open or drain position.

Referrin now to the drawing, the reference character in designates a portion of a sink or the like provided with a drain opening D in which a" device made according to the invention is mounted. The tubular. memberor body ll positioned in opening D is provided with a flange I2 which rests on the top of the wall of the container or sink I0. The tubular member II has 5 Claims. (Cl. 4-9287) a strainer receiving portion Ha which is threaded externally at 12a toreceive a threaded clamping nut M. This nut acts to clamp the Washer 15 against the underside l6 of the wall of the sink or container 10 to form a water-tight joint.

Adjacent to its lower end the tubular memdberll is; provided with an inwardly directed angular portion IT extending downwardly and inwardly from the outer tubular portion Ha with the tapered portion or reduced section formed to provide, a valve seat l8. Just below the valve seat It is a portion of narrower diameter, for example an inwardly directed annular bead or shoulder 3 to provide for the operation of the device as will be described. The lower end of the tubular portion I9 of the member II is provided with openings formed by cross straps 20a to form .a

supp mental stra n Connected to the lower end of the tubular portion I9 and forming an extension thereof is a tube 2! having a flange 22 which is held against the washer Z3 abutting the nderside of the n- Wardlydirected flange l9a on the tubular portion l9 by the coupling orclamping member 24.

Removablymounted within thetubular strainer receiving portion Ha is a strainer or perforated container 25. This container 25 has a flange 25a that rests on a shoulder 26 defined by a recess 26a which is provided on the flange 12 of the. tubular body ll.

3 A bushing or sleeve 2-! is mounted preferably in the. exact center of this perforated container 25; A center post or stud 28 which has a knob 28a on one end and a threaded section 29 on its lower end is slidably carried in the bushing 21 and is assembled with a stopper 30. The stopper 30, which can be made of resilient material, such as rubber or plastics or suitable metal, has a suit- "able number of projecting legs or feet 3| which are adapted either to engage the top of the bead B or else be deformed to move past the bead B under pressure on stud 28. When so moved concavities 32 in the feet 3| receive the bead B and act to retain the stopper in a closing position. The valve seat 35 on the stopper cooperates with the valve seat portion l8 of member I I so as to close the outlet from the sink or the like when the strainer 25 is in the lowered position as shown in Figure '1. The reinforcing plate 34 (Fig. 1). in the stopper is used when the stopper is constructed of rubber or plastics or the like as shown and has the threaded socket 34a to facilitate being mounted on the threaded portion 29 of member rod or post 28. When constructed of metalthis plate 34 is not necessary and a threaded socket can be provided on the topper instead. In operation the strainer or perforated container 25 normally remains in a. seated position on the shoulder 26 while the post and stopper assembly are raised and lowered to open and close the drain outlet past the valve seat I8. This same post 28 serves as a handle when it is desired to remove the strainer-stopper assembly from the tubular member H.

The operation of the device will be app from the foregoing description. When it isdesired to keep liouid in the sink or container H] the center post 28 is pushed down to the position shown in Figure 1 so that the feet, legs or extensions 3| on the stop er 3!] snap over the bead or shoulder B of the tubular member II and the head is received by the concavities 32. In this position the valve seat 35 is in the lowered position on valve seat 18 and prevents the drainage positions and then rest on the upper side of the bead B as shown in Figure 5-. In this position the seat 35 on the stopper 30 lies above the seat .portion l8 ofthe tubular member H and the ,liquid may drain from the sink or container ID.

If the water in the sink or container l0 con- .tains solid particles or other solid matter the ,strainer 25 retains them but permits the liquid 'to flow out through the variousstrainer open,-

ings. After the liquid is emptied from the sink or container ID, the strainer or perforated container 425 is removed entirely from the tubular member I i simply by grasping the knob 28a of post 28,

and lifting the entire strainer, post and stopper assembly, and the contents of the strainer 25 are then emptied. After this operation the strainerpost and stopper assembly is returned to the tubular member ll so that its flange 25a rests on the shoulder 26. The feet 3| then lie above the bead B as shown in Figure 5, but can be placed in the position shown in Figure 1 simply by pushing down on knob 28a. g 7 .From the foregoing it will be apparent that it t is not necessary in replacement of the assembly ,to orient the strainer 25 in any particular position in tubular member I l The stopper post assembly may be operated in any position of the strainer 25; that is, the legs or extensions 3l on the stopper 30 may always cooperate with the bead or shoulder B formed on the tubular member ll irrespective of the angular orientation of strainer 25 relative to the longitudinal axis of said tubular member.

While a specific embodiment of the invention has been disclosed, variations in structural detail within the scope of the claims is possible and is contemplated. There is no intention, therefore, of limitation to the exact details shown and described.
