ABSTRACT:
Dispensers for chemicals usually have ball check valves and other moving parts which often corrode due to the action of the chemical. Other types may eliminate the moving parts, but have to be re-charged each time they are used. This device consists of a container having a water inlet and a water outlet at the under end. A U-shaped tube depends within the container and is secured to the inlet and outlet means is provided with a plurality of small holes to allow some of the water to enter a container. An outlet branch is secured within the container, to the outlet means and water is picked up from the container by the outlet branch and joins the mainstream of water passing through the U-shaped tube. Chemical in a fabric bag is placed in the container and dissolves in the water in the container and is picked by the outlet tube. When the water is shut off, the container may drain by siphoning action until the outlet branch is reached by the water level which breaks the siphon action so that some water always remains in the container covering the bag in order to dissolve the chemical contained therein.
