) was an English-born American inventor and
manufacturer. He is known as
"The Soda Fountain King".
Matthews manufactured carbonating machinery and distributed his
product through retail stores. The equipment was a lead-lined
cast-iron box where carbonic acid gas was formed by mixing
sulphuric acid with marble dust. The gas was then purified by
passing it through water, and then into a tank partially filled
with cool water. The tank was rocked for a quarter to a half hour,
until the water was impregnated and bubbly.
Matthews created a fountain apparatus that could be positioned on a
pharmacist’s counter to dispense carbonated drinks, leading to its
popularisation and rapid growth.
