VEIQ'TED WATER-CLOSET BOWL.

Specification of Letters Patent. 1

- Patented July 5. 1910 T all whom it may concern:

Be it known that 1, JOHN F. KnLLY, a citizen of the United States, residing at Trenton, county of Mercer, State of New Jersey, have invented certain new and useful Improvements in Vented lVater-Closet Bowls; and I do hereby declare the following "0 be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

My invention relates to vented water closets and has for its object to provide a venting duct for closet bowls in which the inlet of said duct is located above the rim of the bowl, so that in case the bowl be comes clog ed the contents will flow over the edge of the bowl and none of the overflow will enter the duct, and furthermore that by locating theinlet of said ventilatingtluct so as to overlierthe rim of the bowl and in proximity to the rear thereof, the position of said duct is that best calculated to zause said duct to receive and carry off all gases that may accumulate in the bowl and zo maintain a constant'draft across the top if the bowl, and thus keep the bowl free From oitensive odors and noxious gases.

In the types of vented closets as heretoore employed, the inlet or inlets of the -ventng ducts usually open into the interior of he bowl below the rim and but a relatively hort distance above the normal level of the water in the bowl, so that any appreciable ise of the water will cover said inlet and top the venting action, floating matter will and to clog the duct, and little of the gas 1 the bowl above the inlet ofwthe duct will nd its way thereto, the gas-tending to es- 1P6 directly into the room or to be trapped l the flushing rim so as to esca e into the om during the succeeding flus ing opernon.

The resent invention is designed to ob: .ate all of the objections inherent in the d forms of vented water closets and beuse of the particular location and arrangeent of the inlet of the venting duct, all

the gases within the bowl rise directly the vent and pass off through the stack;

rthermore by no possible chance can any reign matter enter and clog the vent ould the water rise in the bowl, because a inlet of the vent is located above the rim the bowl.

In the accompanying drawings. Figure i is a vertical section through a water closet bowl involving the invention, Fig. 2 is a plan View with the ventilating duct shown partly in section, Fig. 3 is a fragmentary section showing an alternative arrangement of water inlet.

Referring to the drawings, a indicates the closet bowl which in the example illustrated. is of the siphon jet type involvin a flushing rim 0, a siphon discharge (1, a et duct e, which communicates by way of passage j with a water supply chamber 5 atthe top and rear of the. bowl, which chamber 2' also communicates with the rim 0, as will be und stood. Formed on the. upper surface of the bowl above the supply chamber 1'- and the discharge siphon is a hollow generally arch shaped projection gtorming with the top wall of the closet an unobstructed chamber 7.: which has an inlet 0 overlying the rim of the bowl at the rear of the said rim 0, and an outlet 7 formed as a horizontal neck adapted to be connected with a. vent or stack. The top wall of the extension 9 extends completely to the top opening of the bowl, as shown, and the inlet opening or mouth of said extension extends substantially parallel with the rim of the bowl. It will be particularly noted that there is thus produced a ventilating duct which opens into the closet bowl a above the rim 0 so that should the bowl overflow, the overflowing matter cannot enter said ventilating duct or any part thereof; also thatthe opening 0 forming the inlet for said ventilating duct is relatively large and extends for a considerable distance around and above the rear portion of rim 0, thereby forming with the arched top wall 9 of the duct :1 species of hood or cowl to catch the gases arising from the bowl.

The water supply duct is conveniently formed integrally with the ventilatin duct and, as indicated in Fig. 1, comprises a 100 coupling nipple or horn f mounted on top of the wall g of the ventilating duct and connected with chamber 2' by one or more passages it formed within the body of the arch-like wall Instead of (is osirg the water inlet on' the top of vent diet is, as indicated in F ig. 1, the said inlet may be located below said duct and formed as a horizontal rearwardl Y ex tendmg horn f, see Fig. 3, so that the l. A water closet bowl having an integral ventilating duct located wholly above the top of the bowl, the inlet mouth at the end of said duct bein located above the rim of tile bowl and su stantially parallel therewit 2. A water closet bowl having a ventilating duct comprisin a hollow integral extension mounted on t e upper surfaw at the overlyin rear of the bowl and having a top wall extending completely to the top opening of the bowl, the inlet opening or said extension 4 the rim of the bowl and being substantially parallel therewith.

3. A water closet howl having a flushing rim, a ventilating durt comprising a hollow integral extension mounted on the upper surface of the bowl at the rear thereof rovided with a downwardly directed inlet openin above the rim of the bowl and substantia ly parallel therewith, a horizontal outlet neck, and a Water supply duct formed in the wall of said extension at the side of said outlet neck.

In testimon whereof I afiix my signature, in presence 0 two witnesses.

JOHN F. KELLY.
