BASIN AN D WATER-CL'OSET VALVE.
SPECIFICATION forming part of Letters Patent No. 289,937, dated :December 11, 1883.
Application filed March 31, 1883. (No model.)
To @ZZ whom it may concern:
Be it known that I, HOLLAND SMITH, of San Francisco, county of San Francisco, State of California, have invented an Improved Basin and Water-Closet Valve; and I hereby de` clare the following to be a full, clear, and eX- act description thereof.
My invention relates to certain improvements in valve-connections for basins, sinks, and for other similar purposes.
It consists of a mechanism more fully explained by reference to the accompanying drawings, in which- Figures 1 and 2 are partly sectional views of my invention.
I have illustrated my invention in the present case as applied to a wash-basin having hot and cold water supply pipes and a waste-discharge pipe; but -it will be manifest that practically the same mechanism will be applicable to a sink or other place where there arey one or more supply-pipes and an exit, waste, or discharge pipe, either with or without a trap.
A is a lbowl properly set, and having the supply-pipes'B C -for hot and cold water, and the stop-cocks D and E.
Fis the waste-pipe, which leads from the bot- 1 tom of the bowl, and may have a trap of any dev scription,if desired. Thewater-supplypipesB C and the Waste-pipe are brought near enough n together at some point below the bowl to allow the valves H, which control them, to be operated by a single shaft, G, to which they are connected. In the presentcase the valves are of a rotary pattern, and are so arranged that they all will be opened or closed together, but they may be also arranged so thatv one' -or more will be opened and the other closed by the action of the shaft.
I is an arm or crank, which is connected When the bowl is to be used, the foot may I be placed upon the treadle and all the valves H will be opened. The plug M being in the discharge-opening of the basin, the cocks D or E may be opened and water drawn for use. After use the plug M may be withdrawn and the contents allowed to escape through the waste-pipe. rIhe treadle being released, the valve H will be closed at once and no water can run; neither can there be any escape of sewer or other noxious gases fromthe waste pipe. The valve acts as a perfect seal. The water-valves are closed as soon as the treadle is released, so that if the cocks D or E should be carelesslyleft open there would be no iooding, as the supply would be cut off instantly when theV person released the treadle to go away. y
Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is-
A basin or sink having supply-pipes B andv l C, cocks D E, outlet-pipe F, and valves H, as herein set forth, in combination with the shaft G, lever,.I, pitman K, treadle J, and spring L,
arranged to keep the valves H normally closed, as herein described.
In witness whereof I hereunto set my hand and seal.
