1 Claim.

The invention relates to Water closet tanks and has for its object the prevention of rise of Water in the tank under any conditions above a predetermined level. To this end the invention consists in the construction as hereinafter set forth.

In the drawings:

Fig. 1 is a perspective view of a water closet tank of my improved construction;

Fig. 2 is a vertical longitudinal section through the tank;

Fig. 3 is a horizontal section on line 3-3, Fig. 2;

Fig. 4 is a vertical section on line 4-4, Fig. 2; and

Fig. 5 is a section on line 5-5, Fig. 2.

Tanks for water closets are usually provided with an overflow conduit for limiting the rise of the water level therein. However, the overflow conduit is itself connected with a drain conduit and in case of stoppage in the latter, water within the tank will rise to a higher level. One important purpose for restricting the height of water in the tanks is to maintain this level below the discharge from the ball cock so that in case of leakage in the latter and suction occurring in the water line no water can be siphoned from the tank back into the line.

My improved tank A is provided with the usual overflow conduit B preferably formed integral with the rear wall A and connected at its lower end by a passage B to the trap C of the water closet D on which the tank is mounted. In addition to this overflow there is provided an emergency overflow or spillway located at a slightly higher level and functioning to prevent further rise of water in the tank in case the regular overflow is clogged. This spillway I preferably form by inwardly offset channel portions E formed in the upper part of the rear wall A extending down to the desired spill level and having a constantly open port F between the same and the main portion of the wall. The area of the ports F is sufiicient for the escape of water therethrough as rapidly as it can be supplied to the tank. Thus, if the regular overflow outlet fails to function, the

water in the tank will not rise above the lower end of the channels E. The water is supplied to the tank through an inlet conduit G having at its upper end the ball cock H. This is sufliciently above the level of the spillway to preclude the possibility of siphoning water from the tank back into the supply line.

The construction, as shown, is one which can be easily manufactured as the ofisets E may be formed when the tank is molded, establishing an exactly predetermined level for the ports F which will be the same in all tanks. This might not be true if the port were punched through the wall of the tank. There is a further advantage in forming the ports F by the inwardly offset portions E viz., that they are concealed from view of anyone looking into the tank. As a matter of fact the ports F are only for emergency use and water will never pass therethrough unless the regular overflow passage is stopped. However, if the ports were visible, the purchaser might consider the tank defective. The construction is also one which can be easily manufactured and without additional expense.

What I claim as my invention is:

In a water closet tank provided with an overflow conduit for connection with a drain, a spill opening located in the rear wall of said tank formed by an inwardly offset upper portion of said wall with its outer surface spaced from the inner surface of the wall portion immediately below the same to form a concealed upwardly opening large capacity port.
