Tatsuno’s Patent Gasoline Measuring Equipment Type No.25
Uchu Tatsuno, the founder of Tatsuno Seisakusho (currently TATSUNO Corporation), acquired patents for gasoline measuring equipment and a safety device for underground gasoline storage for the first time in Japan, and thereby created the country’s prototype gas station.
The machine shown here made its debut as the last purely mechanical measuring equipment and was manufactured in 1937. It pumps up gasoline stored in an underground tank with a manual pump to a glass container above. By reading the level difference between the sliding pipe and the reference pipe in the glass container, a supply of gasoline in units of five liters or 1 gallon was made possible. The machine served as the foundation of commercial gasoline measuring equipment.
