- -'6 Claims; (01. 4-287);
This invention relates to 'improvements'in the construction of strainers and waste valves. for
use in sinks or thelike.
An object of the invention is to .provide a combination sink strainer and waste valve, the valve having two positive normal positions, one fully open and the other fullyclosed. I
A further object of the invention-is to provide a combination'sink strainer and waste valve which maybe easily and inexpensively manufactured and assembled and which may. be easily disas sembled for the purpose. of cleaning.
Still a further object is to provide a combina tion sink strainer and'waste valve in which the 4 valve may be :operated independently of the strainer so that the strainer may remain stationary when said valve is operated.
These and other objects are attained by the means described herein, and disclosed in the ac- 2Q companying drawing, in which:
Fig. 1. is a sectional View of the strainer and valve comprising the invention, the valvebeing in an open position.
Fig. 2 is similar to Fig. 1, showing the valve in a closed position. g 1
, Fig. 3 is an assembly view of the valveand valve stem structure comprising the invention.
Fig. 4 is a view taken on line 4 -4 of Fig. 3.
Fig. 5 is; anassembled view of the valve and valve ster'n cornprising the invention, partly in cross-section for clarity of detail.
Fig.6 is a fragmental view showing adetail of the invention.
Thedrain comprises an outer shell Ill having 5 an annular flange I l disposed to engage the edges of a suitable: aperture I2, provided through the bottom N2 of a sink, not shown. The outer edge of shell it is provided with a threaded portion.
#3 for cooperating with a suitable clamping nut I4 for securing shell Ill to the sink. Any suit; able packing gland or washer asv I5 may be used to form a fluid. tight connection between shell H] and sink l2.
The lower. edge of shell Ill converges to form a constricted outlet passageway It, the outer wall of which is threaded as at ll for suitable con nections to a waste pipe or trap, not'shown.
An annular valve seat-|8. is provided internally;
of constricted passageway It, said seat tapering inward from a point of maximum width where it intersects the convergent bottom I9 .of shell l0.
A strainer basket 20 isremovably positioned within shell [,0 and maintained in. spaced relationship therewith by means of the out turned annular flange 21 whichcooperates with an annular seat 22 provided in shell lll..- Said strainer is provided with suitable drain holes 5%. -An up ward extending abutment 23 is provided centrally of strainer basket 20 being secured in place by any suitable means such as-by welding lip 24 to. the 5 under side of said basket.
, An' annular valve 26 is adapted to cooperate With valve seat 18 whereby a fluid tight seal is provided when the valve is seated as shown in Fig.2.
:Valve 26 is carried by a composite valve stem 21 which'comprises a lower section 28 and an upper section 29 which is pivotally connected to said lower section. Lower section-28may be made integral with valve -26 as shown in Figs. 3 and 5.; 20 A transverse cross-sectional plane through said I valve stem is complementary in shape to aperture 25 which extends throughabutment 23, whereby to permit said valve stem to be moved vertically throughaperture 25 but precluded from being ro- 25 tated within said aperture. A pin-3i] is fixed rela- I tive to bottom valve stem section 28 and extends outwardtherefrom; asshown in Figs. 3 and 5, Pin 30 maybe formed integrally with section 28 or it may comprise a separate pin secured to sec- 30 tion 28 by means of a weld or a force fit.
Upper valve" stem section 29 is secured in a swivel relationship with lower section 28 by means of pin. 3ll, the free upper end ofwhich is peened over the upper end of section 29, as clearly shown 35 inFig.5. A suitable handle or; knob 31 may be fastened to the upper end of section,29 by any suitable means such as threads 40. The peened end of pin 30 may be housed within the knob 3! as 49' 1 Valve 25 may be moved only vertically towards or away from its seat l8, being prevented from] being rotated relative thereto by reason of the non-circular shape of valve stem 2'! and aperture 25 within which ,itymoves. -The strainer acts, .5
Valve 26 is caused to seat by turning knob 3! a suflicient amount to align the upper section 29 with aperture 25 thereby permitting section 29 to drop into said aperture of the abutment v23, as clearly shown in Fig. 2. This is the fully closed position of said valve. It should be here noted that valve 23 has but two normal positions, via, either fully open or fully closed. In this way, troublesome intermediate settings have been eliminated and a positive acting waste valve is simply provided.
If desired, an auxiliary strainer 33 may be placed in the lower end of outlet passageway [6, said auxiliary strainer being supported by suitable means such as annular flange 34.
The entire valve assemblage and strainer basket may be removed by lifting up on knob 3| so that the upperface 35 of valve 26 contacts the bottom of said basket whereby the entire assemblage may be removed from shell l0 thereby permitting access to auxiliary strainor 33 and to valve seat lfifor cleaning purposes and the like.
From the foregoing it is' obvious" that I have provided a simple, yet positive acting sink strainer and waste valve assembly which may be easily manufactured and assembled, and which, once assembled, is trouble free since there are no pins, slots or notches which may become damaged.
Further, it should be noted that I have provided a drain valve which is not given a rotary motion relative to its seat when it is seated or unseated, since valve .26 is constrained to move vertically toward or away from its seat [8 whereby undue wear between said valve and its seat is eliminated. Further, I have effectively eliminated any relative motion between strainer basket 20 and the valve and/or valve stemwhen said valve isbeing opened or closed.
It is to be understood that various modifications and changes in the structural details of the device may be made, within the scope of the appended claims, without departing from the spirit of the invention.
