AUTOMATIC DISPENSER FOR DISINFECTANT AND BOWL CLEANING FLUID ABSTRACT OF THE INVENTION An automatic dispenser for disinfectant and bowl cleaning material adapted to be suspended stationarily in the tank of a flushing bowl wherein the dispenser comprises a container with ball valve floated against the tapered in- terior of an upper opening in the container and an adjust- able drainpipe in the bottom of the container with the ad- justable drainpipe having an upper tapered opening and a ball valve for closing the same as well as lower openings extending downwardly outside the container providing pass- age for container water or tank water as the case may be. In operation the two ball valves are floated to the top of their respective openings sealing the openings and isolat- ing the water in the dispensing container. The dispensing container is provided with preferably a block of soluble disinfectant cleaning material such as a hypochlorite which will dissolve very slowly into the water in the container. When the tank is flushed, the water level in the container drops together with the water level in the tank thereby displacing the container and drainpipe ball valves allowing the disinfectant solution to be dispensed. The disinfec- tant solution flows out through the drainpipe, and openings in the drainpipe extending below the lower level of the container, into the tank and eventually to the bowl. When the flushing operation is finished, the rising of the water ABSTRACT OF THE INVENTION (cont'd.) in the tank permits the ball valves to close. No water is dispensed into the tank water at the beginning of the re- filling of the tank. The drain ball-valve rises with the rising tank water, eventually fitting tightly to the tap- ered opening. Then, tank water on the outside rises until reaching the upper opening. The device is refilled with fresh tank water until the ball stop closes the upper open- ing. No mechanical or other operating devices are required other than the two floating ball valves and the operation of the device is entirely in response to the flow of water into and out of the toilet tank so that the operator need not even be aware that a dispensing device is located and operating therein.
