COMBINED DRAINAGE STOP-VALVE CONlICAL STRAINER DEVICE Existing pop-up drain valve in lavatory or wash basin plumbing drains consist of large drainage bores with no provision or means to prevent elongated obstructive solid matter such as bobby pins, hair pins or the like, and other entrapments from washing into the drain, such elongated objects lodged in a waste line or trap have a tendency to attract and ensnare lint, hair and other waste matter and to form into a mass, resulting in a stoppage. This is an obvious source of annoyance as well as cost. This invention is more than a conventional pop-up stop-valve drain and is designed for insurance against stoppages.
After more than 40 years of experience as a plumbing contractor, I have become aware that the average home owner or tenant has not escaped a plumbing drain stoppage. It seems to be universal. inadvertently human failure comes into play and I have known persons to lose precious items down the drain.
It is therefore a primary object of the invention to provide an improved pop-up lavatory stop-valve drain with a combined stop-valve conical strainer configuration adapted to retain all elongated solid waste but permits liquid waste water to flow through the baffle apertures for drainage.
A further object of this invention is to permit easy removal of retained solid waste by the manual liftable stop-valve head, when the flow of drainage is retarded.
These together with other objects and advantages which will become apparent, reside in details of construction and operation as more fully described and claimed, reference being had to the accompanying drawings forming a part hereof, wherein like numbers refer to like parts throughout, and in which FIG. 1 is a vertical section view showing the combined stopvalve strainer device and drainage apertures.
FIG. 2 is a horizontal plan view of FIG. 1 on line 2-2 showing the stop head, circular post and base and curved drain apertures.
FIG. 3 is a horizontal sectional view of FIG. 1 taken on line 33 showing the conical configuration strainer catch like basin.
FIG. l-A is a vertical section view of a second embodiment of the device showing the combined stop-valve strainer device and the elongated drainage bores.
FIG. 2-A is a horizontal plan view of FIG. l-A taken on line 2-A 2-A showing the stop head strainer body and elongated drainage bores.
FIG. 3-A is a horizontal sectional view of FIG. l-A taken on line 3-A- 3-A showing the conical configuration strainer.
The combined drainage stop-valve conical strainer device preferably is to be constructed in plastic with a metal facing over the stop head seat.
Turning to FIGS. l-A, 2-A and 3-A the drawings, the numeral 10 designates the stop-valve, having a metal covered facing 11 extending to the tapered portion of said valve 12 for seating, having enlarged drainage bores 31 therebeneath communicating with baffle apertures 17. In FIG. 1 stop-valve 10 is integral with the circular post 13 resting on the circular base 14, said circular base 14 is provided with elongated curved drain apertures 15 permitting drainage into the combined upwardly and outwardly tapering conical strainer 18. The improved feature of the conical strainer device resides in the provision of bafile apertures 17 in its inclined wall 16 and embodied with an enclosed bottom wall 19 permitting liquid waste water to pass but preventing elongated solid waste objects from passing into the drainage system. Said conical wall 16 is inclined at an angle of approximately 20 to said strainer, longitudinal axis and permitting ample space to drainage opening 20 and communicating with the brass housing 21 as shown broken in part in FIG. 1 and FIG. l-A. Another feature of this invention is that the stop-valve conical strainer device is designed in a single functional unit. Said conical strainer 16 is provided with an enlarged lower external base 22 therebeneath and co-acts with the conventional pop-up lavatory drain for drainage and seating, said conical strainer projects upwardly; and positions vertically to the upper portion of the strainer 3 for alignment and co-acts freely with its brass housing member 21 shown broken in part and permits east of disposal of solid entrapments by manual removal of the combined drainage stop-valve conical strainer device.
I CLAIM:
1. In a combined conventional lavatory fitting pop-up drain valve, having a manually liftable stop-valve for drainage and seating, removable and embodied in a brass housing disposed in a wash basin, said liftable stop-valve having large drainage apertures to permit waste water to pass into said apertures and from said apertures to the drainage system, said stop valve having a metal facing extending to the tapered portion of said drain valve, the improvement, essentially consisting of a com bined stop-valve conical strainer configuration, adapted to fit into the said brass housing for drainage and seating, said conical strainer configuration tapering inwardly and downwardly and having a flat bottom wall for entrapping elongated solid waste matter, said bottom wall having an enlarged lower base, co-acting freely with a pop-up drain, said conical strainer projects upwardly to an elongated vertical position for free alignment within its brass housing, a plurality of bafi'le apertures disposed in said conical strainer wall, said conical wall being inclined at an angle of approximately 20 to said strainer longitudinal axis, whereby said strainer permits liquid waste water to flow through, said baffle apertures but prevents elongated solid objects from passing therethrough.
