warns-omens ATTACHMENT.

Application filed January 5, 1922. Serial no. 527,211.

To all whomz't may concern-1 Be it known that we, JAiuns W. RAMSDELL and FREDERICK if. l i insr. citizens of the Unitec States, residing at Lalreland, county of Polk, State of Florida, and Tampa, in the county of llillsborough and State of Florida, respectively, have invented certain new and useful Improvements in "Water- Closet Attachments, of wh ch the following is a specification. i

This invention relates to water closets,

and has for its object to provide an 1111- proved device adapted to prevent the flow of water to the closet if and when the closet bowl becomes full and in danger of overflowing.

Closet bowls and the waste pipes therefrom frequently become clogged, and this clogging is often followed by one or more operations of the flush tank. resulting in overflowing and disagreeable renditions. By means of the present invention l provide an automatic valve which is operated by a float located in the bowl, and when the water rises to a certain heighth in the bowl, the valve or valves close and auto matically shut off the further flow of water from the flush tank.

The invention may be embodied in various forms, one of which is illustrated in the accompanying drawings, in which Fig. 1 is a partial horizontal section of the upper part of a bowl provided with the improvement. Fig. 2 is a section on the line 2-2 of Fig. 1.

In the drawings, the body of the bowl is indicated at 10, the rim at 11 and the inlet chamber to the rim at 12. This inlet chamber communicates with the hollow 13 of the rim, so that water may flow around the rim of the bowl and is discharged into the bowl through holes 9 in the under part of the rim. This rim overhangs the side of the bowl inwardly.

At or in front of the inlet chamber 12 the rim of the bowl is provided with a wall 14; which defines a part of the water passage 13, and at each end of this wall 1 1 1 form a circular valve opening 15 which permits flow from the inlet chamber 12 to the hollow rim. Each of these openings is controlled by a ball valve 6 which may also seat at 16 at the upper end of an opening 8 extending through the lower wall of the rim and provided with a valve seat 18 at its lower end. Each ball 6 is flexibly or loosely connected toa valve member 7 q carried by a circular float 20 having the form of a ring which fits in the space under the rim of the bowl and is adapted to be lifted when thewater in the bowl reaches the heighth thereof; The connec tion between each ball valve 6 and the float may be of various forms. l have shown a short rod 21 which hasa ball and socket joint 22 with the apex 'ofthe valve member T, and aloose or ball and socket joint 23 with the ball 6. Instead of this jointed rod, a flexible connection such as a spiral spring may be substituted, and the ball is preferably made heavy enough to tend to seat by itsownweight ontheseat 16, and, when the floatis lifted, the balls are lifted from the seats 16 and in consequence of the water pressure and direction of flow they will swing over and seat at the openings 1:") between the supply chamber and the hollow mm.

In operation, the float will normally remain in lowered position, with the valves 6 resting against the seats 16. This permits the water to flow from the supply chamber through the ports 15 to the hollow rim, and the closet operates as usual. When. the closet becomes clogged the rise of the water will lift the float 20 and thereby raise the valves 6 permitting them to be forced by the water pressure against the seats 15, thereby sealing the passages to the hollow rim and cutting off the water supply. And at the same time, the valve members 7 will rise with the float and close against the seats 18, thereby closing the holes through which the connections 21 work and preventing the escape of any water through said. holes. When the float falls the reverse action occurs and the parts are restored automatically to original position.

The structure therefore provides automatically actuated means for cutting 0fi the water supply to prevent overflowing, and no manual operation is necessary either to prevent said flow or to restore normal conditions when the clogging is relieved.

The invention may be embodied in various forms and no limitation in this respect is implied.

We claim:

1. The combination with a closet bowl having a supply chamber at the rim thereof, and. an outlet from said supply chamber to the rim, and an opening in the lower wall of said supply chamber, of a float in the bowl, and a valve located in the supply chamber and flexibly connected to the float and controlling said outlet and said opening respectively, said valve being adapted to close said outlet when the float is lifted and to close said opening when the float is lowered.

2. The combination with a closet bowl having a supply chamber at the rim thereof and a hOllOW rim having outlets into the bowl and also having an opening conmeeting the supply chamber and the rim and another opening into the bowl, of a float in the bowl, a valve in the supply chamber, movable from one opening to the other to close either, and a flexible connection between the float and the valve, said connection extending through the last mentioned opening. a

The combination with a closet bowl having an overhanging rim and supply chamber, an opening from the supply chamber to the rim, and another opening in the lower wall of the supply chamber, of a float located in the bowl, a ball valve movable in the supply chamber to close either of said openings, a flexible connection between th float and the ball valve, said connection extending through the opening in'the lower wall of the supply chamber, and a valve member carried by the float and adapted to close upwardly against said opening in the lower wall or" the supply chamber when the float lifts.

4. The combination with a closet bowl JAMES w. RAMSDELL. FRED o. wIEsr.
