Title: Water level indicating buzzer for bathtub
Inventor: YAMAMOTO KEINI
IPC: G01F23/60
Filed: 1979-12-03
Abstract: PURPOSE: To make it simple to operate, by putting a switch and a buzzer, which are designed to be turned on when angles of a battery and a mercury switch, etc. changed, into a waterproof case and also by attaching a clasp to this through a string.  
     CONSTITUTION: A water level detector main 8 is suspended along side wall in a bathtub by means of a string 9 and a clasp. When the bathtub started being filled with water and as the water level is still low, a mercury switch 4 is still in OFF position and a buzzer 3 is not sounded. When the water level became higher, because of eccentricity of the center of gravity of the detector main 8, it is turned upside down turning the mercury switch 4 ON and sounding the buzzer 3.
