Level actuated apparatus for delivering chemicals

Claim 1

An apparatus for delivering measured amounts of chemical solution upon actuation of a cycling fluid level which comprises: a. a solids chamber adapted to contain solid soluble chemicals or a mixture of solid soluble chemicals and ballast material, b. a refill chamber having an open top end situated above the top of said solids chamber, c. first means for providing fluid communication between said refill chamber and said solids chamber which permits fluid flow from said refill chamber into said solids chamber and which prevents reverse fluid flow from said solids chamber into said refill chamber, d. a discharge chamber extending above the top of said solids chamber, e. second means for providing fluid communication between said discharge chamber and said solids chamber, f. a pump chamber having an open bottom portion and a top portion extending above the top of said solids chamber, g. third means for providing fluid communication between the top of said pump chamber and the top of said discharge chamber, h. a siphon tube having an inlet end into said discharge chamber at a point between said second and third means, having a portion of said siphon tube extending above the inlet and having an outlet end located below the inlet end.

Claim 2

An apparatus for delivering measured amounts of chemical solution upon actuation of a cycling fluid level which comprises: a. a solids chamber adapted to contain solid soluble chemicals or a mixture of solid soluble chemicals and ballast material, b. a refill chamber having an open top end situated above the top of said solids chamber, c. first means for providing fluid communication between said refill chamber and said solids chamber which permits fluid flow from said refill chamber into said solids chamber and which prevents reverse fluid flow from said solids chamber into said refill chamber, d. a discharge chamber extending above the top of said solids chamber, e. second means for providing fluid communication between said discharge chamber and said solids chamber, f. a pump chamber having an open bottom portion and a top portion extending above the top of said solids chamber, g. third means for providing fluid communication between the top of said pump chamber and the top of said discharge chamber, h. a siphon tube having an inlet end into said discharge chamber at a point between said second and third means, having a portion of said siphon tube extending above the inlet and having an outlet end located below the inlet end.

Claim 7

An apparatus for delivering measured amounts of chemical solution to trap of a toilet bowl upon actuation by the flushing cycle of the toilet which comprises: a. a solids chamber adapted to certain solid soluble chemicals or a mixture of solid soluble chemicals and ballast material, b. a refill chamber having an open top end situated above the top of said solids chamber, c. first means for providing fluid communication between said refill chamber and said solids chamber, d. a check valve which permits fluid flow from said refill chamber through said first means into said solids chamber and which prevents fluid flow from said solids chamber through said first means into said refill chamber, e. a discharge chamber extending above the top of said solids chamber, f. second means for providing fluid communication between said discharge chamber and said solids chamber, g. a pump chamber having an open bottom portion and a top portion extending above the top of said discharge chamber, h. third means for providing fluid communication between the top of said pump chamber and the top of said discharge chamber, i. a siphon tube having an inlet end into said discharge chamber at a point between said second and third means, having a portion of said siphon tube extending above the inlet and having the outlet end suitable for inserting into the overflow pipe at a toilet with an outlet of said siphon tube located below the inlet end and further located within about four inches from the bottom at the overflow pipe.

Claim 8

An apparatus for delivering measured amounts of chemical solution to trap of a toilet bowl upon actuation by the flushing cycle of the toilet which comprises: a. a solids chamber adapted to certain solid soluble chemicals or a mixture of solid soluble chemicals and ballast material, b. a refill chamber having an open top end situated above the top of said solids chamber, c. first means for providing fluid communication between said refill chamber and said solids chamber, d. a check valve which permits fluid flow from said refill chamber through said first means into said solids chamber and which prevents fluid flow from said solids chamber through said first means into said refill chamber, e. a discharge chamber extending above the top of said solids chamber, f. second means for providing fluid communication between said discharge chamber and said solids chamber, g. a pump chamber having an open bottom portion and a top portion extending above the top of said discharge chamber, h. third means for providing fluid communication between the top of said pump chamber and the top of said discharge chamber, i. a siphon tube having an inlet end into said discharge chamber at a point between said second and third means, having a portion of said siphon tube extending above the inlet and having the outlet end suitable for inserting into the overflow pipe at a toilet with an outlet of said siphon tube located below the inlet end and further located within about four inches from the bottom at the overflow pipe.
