Remote detector to indicate leakage of liquids in toilet tanks

Claim 1

A remote detector to indicate discharge of electrically-conductive liquid from a stationary tank having at least one outlet pipe, comprising: an annular support member of electrically-insulating material located within said outlet pipe; a pair of arcuate electrodes constituted by respective curved plates of electrically-conductive material, the curved plates being secured at their convex surfaces to the interior of the annular support member at substantially the same position along the outlet pipe but being spaced apart from one another about the inner perphery of the annular support member; first and second electrical conductor members connected to the electrodes respectively; and remote indicator means connected to said first electrical conductor, whereby when said second electrical conductor and said remote indicator means are connected to respective terminals of a source of electrical energy, an electrical circuit through the remote indicator means is completed, thereby to energize the indicator means, when electrically-conductive liquid establishes electrical contact between the electrodes.
