SINK-ST 01?.

Specification of Letters Patent.

Patented Oct. 12, 1969.

Application filed January 23, 1908. Serial No. 412,346.

To all "whom it may concern:

lie it known that l, ()swnno Jmrns lJnnmy, subject of the King of Great Britain, residing in the town of Port Arthur, in the rilgonia, in the Province of Ontario, .in the Dominion of Canada, have invented certain new and useful Improvements 'in Sink-Stops. of which the following a.

specification.

The invontion'relales to improvements in sink stops, described in the present specili ration and illustrated in the accompanying drawings that form part of the same.

The invention consists essentially in closing the opening to the waste pipe with a plug aranged beneath the outlet opening plate at the lower end of the threaded spindle introduced into a correspondingly threaded orifice through said outlet plate.

The object of the invention is to devise astop in which the means for operating is positive, thereby freeing the outlet from all danger of clogging. I

in the drawings, Figure 1 is a sectional perspective view of the device as applied to a sink. Fig. 2 is a cross sectional View of the outlet plate and stop inserted theretl'irough.

Like numerals of reference indicate corresponding parts in each figure.

Referring to the drawings, 1 is the outlet plate centrally perforated with the plurality of holes 2 and having the screw holes fl toward each side edge.

l is the sink bowl huvingthe outlet opening 5 closed in by the said plate 1 and having beneath said outlet opening the cup 3 foriaing at its lower end the valve seat 7 and leading to the waste pipe 8. V

l) is a threaded spindle having" the knurled head l0 and introduced into n central threaded orifice 11 extending through the outlet plate 1 and. block or nut l rigidly soenroll to said plate on the underside thereof.

12?- is :i nut arranged on the said spindle 9 intermediate oi its length.

les a plug or stop preferably formed of r silient material, such rubber, and. haviugr a ecnlrul orifice therethrough and niouuti'ed on the spindle 9, being securely held thereon against the'nut 13 by the nut at the lower end said spindle, a suitahlc sher it; being introduced between said nut 1 l5 and the lower side o't said plug or stop. Said plug or stop ll is of hall. ball form, the llat side thereof being arranged at the top' and the curved portion engaging the valve seat 7. ondcr to close the opening to the waste pipe, the spindle is screwed downwardly until the plug or stop 14: closely engages the seat 7 and prevents the egress of water or other liquid from the sink bowl 4, and in order to flush the sink out, the spindle l) is turned in the threaded hole and the plug or stop 14, thus positively lifted from its seat '7, leaving the opening to the waste pipe 8 pcrl'ectly tree.

The advantage of this simple and positive means of closing the egress opening from a sink bowl, obvious to those having ex perience with many forms o'l? stops used in basins and bowls and baths and so forth, as not only is thocoinnion form of plug quite inappropriate for sink construction but other and more con'iplicated arrangements are both expensive and unnecessary. In addition this form of stop may be used for other bowls, besides sink bowls, though the particular object of the invention as stated in the foregoing to devise a. stop for sinks.

\Vhat I claim as my invention is:

In a sink stop, a plate lfuving a plurality of holes therethrough and a central threaded hole and suitably secured in the sink outlet opening, a threzuled pin having a thumb nut at the top thereof, a semi-ball valve adjustably secured on said pin, and a cup- SlnU Hi-d v: lve chamber rigidly secured to the sink through extending llzingos thereon and having an opcnn'i therefrom at its lower end encircled by a downwardly extending llango and adapted to externally telescope the l upper end of a waste-pipe, the shoulder at 1 the upper end of said downwardly exinnding flange forming a valve seat for said semihall val e.

i Signed at the town of Port Arthur, in the county of iil onuu in the Province of ()ntario, in the Dominion of Canada, this 12 day oi Dec. 1907.
