The present invention relates to improvements in means for controlling the drain outlets of plumbing fixtures, such, for example, as kitchen sinks, wash basins, tubs, etc., and

s has for its object to provide a means by which clogging of the waste pipe trap of such a fixture will be prevented.

It has been heretofore proposed to provide strainers of various forms communicating llo with the drain outlet of a plumbing fixture so thatsolid material contained in iiuid passing through said outlet will be separated and prevented from entering the trap, and the principal object of the present invention is l to provide a means of this general character,

which will be relatively inexpensive and durable, and by means of which the straining receptacle can be readily withdrawn from the waste pipe when desired.

In the accompanying drawings: Figure lis a vertical sectional view through a portion of a plumbing fixture provided with an embodiment of the invention. p Figure 2 is a view of the strainer and waste outlet valve detached from the fixture and on a slightly enlarged scale.

Figure 3 is a section substantially on the line 3 3 of Figure 2.

Figure 4 is a view substantially similar to Figure l, illustrating a slightmodification.

Referring to the drawing, in the several figures of which like parts are designated by the same reference character, l designates the body of a plumbing fixture, for example, a kitchen sink, wash basin, or tub, which, as is customary, is provided in its bottom with a drain outlet, and also has an overflow out- ,ilet 2' in one of its vertical walls. With the drain outlet communicates a waste pipe 3,

which also communicates with a suitable trap, not shown, as is customary. The waste pipe 3 is permanently connected with the fixture l,

and is provided with lateral inlets 4 through which fiuid from the overflow opening 2 can pass.

Within the waste pipe is arranged a strainer receptacle, which, as shown, is provided L at its Lipper end with a valve ,seat 5 arranged coaxially with the drain outlet of the fixture,

and `fiow through such outlet is controlled by a valve 6 cooperating with said seat.

vIn the embodiments of theinvention illustrated, the valve is provided with an elongated stem 7 that extends through the lower end of the strainer receptacle, and, when. the valve is seated, projects some distance below such receptacle within the waste pipe and its connections. As shown, the strainer is provided with an internal upwardly extending 3,

prising a lever 11 and a push rod 12. The

valve seat 5 at the upper end of the strainer receptacle conforms closely to the surface of the fixture or the upper end of the waste pipe, but is not permanently secured in position so that, as hereinafter described, the strainer receptacle, may be, if desired, bodily withdrawn from the waste pipe.

Preferably, as shown, the strainer receptacle is made of downwardly tapering form so that a clear channel is provided between its outer surface and the adjacent wall of the waste pipe, through which water can freely flow. The perforations in the wall of the strainer are of 4such size that while they permit free escape of water therefrom, any solid waste material will be retained and can be readily removed from the strainer when the latter has been withdrawn from the waste pipe asvhereinbefore referred to. ,Y

In using the improvements it will be under- I-IOIVARD W. WEST. stood that normally the valve and strainer RICHARD D. SANDERS.

will occupy the relative position shown in Figure 2, in which the drain outlet is entirely closed. At this time the push rod 12 will be elevated slightly from the position shown in w Figure 1. By depressing said rod the valve will be adjusted into the relation shown in Figure 1, fully opening the drain outlet. With the parts in this position it is possible, by grasping the elevated valve, to lift the strainer receptacle bodily out of the waste pipe, the disc. 10 at the lower end of the valve stem supporting said receptacle. When the matter collected in the strainer has been removed, the latter and valve connected therewith can be readily replaced.

It is believed that the manner of using and advantages of the improvements will be readily understood from the foregoing description and the drawing. The strainer recepta- 5 cle may be formed of any suitable material, 00

either a metal sheet provided with perforations or of wire netting, etc., and, of course, the form of such receptacle can be considerably varied from that shown without depart- .".0 ing from the invention.

What we claim is:

1. The combination with a sink, tub or basin having an outlet and a waste pipe communicating with said outlet, of a valve seat in 35 said outlet, an elongated strainer receptacle 10o within the waste pipe, the bottom of said receptacle comprising an imperforate annulus surrounding the lower end of a tubular guide that extends upward within the receptacle 4U substantially coaxial with the valve seat, a 105 valve cooperating with the valve seat and having a depending stem that extends through said guide of the strainer receptacle and the bottom thereof, means on the valve stem below said receptacle permitting the valve and stem to have a limited vertical movement relative to the receptacle, and means for positively moving the valve and stem upward.

2. The herein described attachment for a sink, tub or basin having a waste outlet, comprising an elongated receptacle having at its upper end a valve seat, adapted to be seated 55 in the waste outlet, a perforated side wall, 120

and an imperforate bottom section surrounding the lower end of av tubular guide that extends upward within the receptacle coaxially with the valve seat at the upper end of the w receptacle, a vah'e adapted to cooperate with 125 said valve seat and having a stem extending through said guide and the bottom of the receptacle, and a projection on the valve stem which is out of Contact with the bottom of 65 the receptacle when the valve is seated in the L 13
