T0015 whom it my concern.

Be it known that I; HENRY R. STOLL, a citizen of the United States residing'a't-El Peso, in the county of El laso and State 5 of Texas, have invented certain new and useful Improvements in Strainers for Sinks and the like, of which the following is a specification.

This invention relates to improvements a in strainers for sinks wash basins, laundry tubs, bathtubs, and in fact all similar plumbing fixtures. 7

One disadvantage presented by the majority of straining fixtures of the class mentioned is that the solid waste matter col lected and retained thereby must be removed by the fingers or in some other nconvenient manner and therefore the present invention has as one of its objects to so N support the strainer member that the same may be readily unseated, the accumulations therein readily dischar ed, and the. said member readily cleaned efore replacement,

'thus'enabling the cleaning. of the strainer to be. efi'ected in a more sanitary and thorough manner.

I The majority of straining devices of the class referred to also present the disadvantags that their perforations are liable to be- 30 come clo god with grease or similar waste matter t us interfering with the draining oil of the waste water in the sink, and therefore the present invention has as a further object to rovide means whereby the perforations 0 such accumulation in. a convenient manner and without the necessity of removing or "dis lacin the strainer.

fort er object of the invention is to provide for the removal and cleaning of the strainer so that the accumulation of use and similar waste matter upon its under side may be prevented, andthe fixture therefore kept in a more sanitary, condition.

In the accompanying drawings:

Figure 1 is a'view in elevation of the fixture embodying the invention installed in a kitchen sink;

Figure 2 is a detail diametric sectional ls shown in Figure 1; and

\ Figure. 3 is a diametric sectional view i taken in a plane at right an ice to the plane of'Figure 2 and through t the strainer may be cleaned-ofsuch f view through the fixture mounted in place v manner firmlg supported wlthln the upper e strainer and.

In the drawings the fixture embodying the invention is illustrated as employed in connection with a kitchen sink but it will be understood that it may be installed in'otherplumbing fixtures of a similarfcharacter. The sink is indicated in general by the numeral l. and its bottom by the numeral 2,

the said bottom being formed at a suitable point with a circular opening .3 and in its upper side with a rabbet or countersink 4 which surrounds the said openin as is usual in such fixtures. The fixture em odying the invention comprises a body which is indi- 'cated by the numeral 5 and which is of cylindrical form and exteriorly threaded as at I 6. This body is provided exteriorly at its upper end with a circumscribing outstanding flange 7. having a portion turned upwardly as at 8 and a portion directed out-. portion 8 of the flange wardly as at 9. The 7 seats snugly within the opening 3, and'the portion}? in the countersink 4. A rin nut 10 is threaded onto thebody 5 and is a a tedto be tlghtened to -bear against the un er side of the sink bottom 2 as best. shown. in

Figures 1 and 2 of the drawings, to bind the flanged upper end of the body 5 firmly to the said sink bottom and within the open ing 3. The waste pipe which leads from the sink and conducts the waste water is indicated by the numeral 11 and the'same is coupled by a con ling nut 12 withthe lower end of the b0 y 5 as'shown in Figure 2. T l

The strainer of the fixture is indicated in general by the 'numeral 13 and the same comprises a-bowl 14- preferably of hollow semi-spherical form althou h it may be made shallower if found esirable. The

strainer bowl is provided substantially throughout its area witha number of perforations 15 through which the wastewater may flow but which will not permit the we sage of any solid waste matter in particles of size as will be liableto clog the waste pipe 11. At its upper ed 0 the bowl14 is provided with an outstan ing circumscribr in flan e16 which rests upon the upper eide of t e flange 7 inwardly of the upstandm in igure 2, the strainer bowl being in this end of the b0 l Within the strainer bowl there is arranged a scraper member, adapted to be manipulated ortion 8 of said flange as clearly shown similar waste matter accumulating upon the inner side of the bowl and interfering with the passage of the waste water through the gerforat-ions 15. This scraper member is in-- icated in general by the numeral 17 and the same comprises a blade 18 which is of arcuate form and of such length and so curved from end to end as to fit within the bowl 14 and extend circumferentially of the inner surface of the wall thereof. The blade .18 is preferably beveled upon its inner side at its opposite ed es to form scraping or shearing edges indicated by'the numeral 1 9. A cross bar 20 extends transversely between the ends of the blade 18 and may be integ" rally connected therewith or secured or connected thereto in any desired manner, and

this bar is provided at its ends with small trunnions 21 whichfit in bearing seats 22 formed at diametrically opposite points in the circumference of the top of the bowl 14,

- ner surface of the wall of the bowl and re-.

the member 17 being in this manner suspendedxby its upper corners for oscillatory motion within it e bowl and so that in such motion its edges 19 may scrape over the inmove any acccumulations upon said surface.

The cross bar 20 constitutes a means whereby Y the scraper member 17 may be oscillated in the manner and for the purpose stated, it being only necessar to rotate this bar between the fingers in or er to effect such movement v of the scraper blade. Also the bar constitutes a handle member whereby the strainer as a whole may be lifted from its seat within the upper end of the body 5. In order that the strainer, after its removal may be conveniently held in the hand while being cleaned, a finger knob 23 is preferably provided upon the under side of the bowl 14 at the central portion thereof.

The stopper of the fixture is. indicated in general by the numeral 24 and may be formed from any material found suitable for the purposeand preferably comprises a fiat circular body 25 the marginal portion 26 of which is adapted to seat more or less snugly in the opening defined by the portion 8 of the flange 7 and .to rest uponthe upper side. 7 of the flange 16 of the strainer bowl. A finger ring or the like indicated by the numeral I 27 may be provided upon the upper, side of the body: 25 of the stopper to provide for its convenient handling in fittingit into place and removing it.

When the stopper 24 is to'be employed,

re eases bowl and out through the waste pipe 1.1,

solid waste matter being collected and ietained however within the strainer bowl from which it may be conveniently discharged, after all of the water has been drained away, bylifting the bowl out of place and dumping its contents, At such time the bowl may be readily cleaned and then refitted into place. if there is no considerable accumulation of solid matter and should the perforations 3.5 become fouled or clogged, this condition may be remedied by rotating the cross bar 20 back and forth between the fingers thus imparting a swinging motion to the scraper member 17 causing its scraping edges 19 to move over the inner surface of the wall of the .bowl.

Having; thus described the invention, what is claimed as new is:

1.. in a device of the class described, a

body, a strainer arranged within the body and comprising a perforated bowl, an arouate blade supported for oscillation within the bowl to be moved over the inner surface of the bowl, and a cross bar extending substantially chordal to the blade and constituting means whereby oscillatory motion may be imparted to the said blade.

In adevice of the class described, a body, strainer disposed within the'body and comprising a perforated bowl, and a scraper for the bowl comprising an arcuate blade, a cross bar extending between the ends of the blade, and bearing elements at the said ends of the blade and bar pivotally seated in the wall of thebowl whereby to suspend the blade for oscillation.

.3. in a device of the class described, a

body, a strainer disposed within the body nanny n. s'roLt. a a]
