In 1907, Desiderio Pavoni, of Milan, Italy, was granted a patent in
Italy for an improvement on the Bezzara system for preparing and serving
coffee as a rapid infusion of a single cup, first introduced in
1903-1904. It is known as the Ideale urn, and makes 150 cups per hour.
Among other Italian rapid coffee-making machines which, with this one,
have attained considerable prominence in Europe and South America,
mention should be made of La Victoria Arduino made by Pier Teresio
Arduino, of Turin, Italy, introduced in 1909, that makes 1000 cups per
hour. It was patented in the United States in 1920. There are, also,
L'Italiana Sovereign Filter Machine (1440 cups per hour) made by Bossi,
Vernetti & Bartolini, Turin, (subsequently merged with La Victoria
Arduino-Societa Anonima); and Jose Baro's Express, Buenos Aires, making
600 cups an hour.

In 1908, A.E. White, Chicago, was granted a United States patent on a
coffee urn. He assigned it to the James Heekin Co., of Cincinnati.

In 1908, I.D. Richheimer, Chicago, introduced his Tricolator to the
trade and the consumer. This is an aluminum device to fit any coffee
pot, combining French drip and filtration ideas, with Japanese paper as
the filtration medium.

In 1908, an improved type of Burns roaster was patented in the United
States. The improvement consisted of an open perforated cylinder with
flexible back-head and balanced front bearing. The following year, the
Burns tilting sample-roaster for gas or electric heating units was
patented.

In 1909, Frederick A. Cauchois, of New York, was granted a United States
patent on a coffee urn fitted with a centrifugal pump for repouring.

In 1909, C.F. Blanke, of St. Louis, was granted two United States
patents on a china coffee pot with a cloth filter, the sides tightly,
and the bottom loosely, woven.

In 1911, Edward Aborn, of New York, was granted a United States patent
on his Make-Right coffee-filter device. This was later incorporated with
improvements in a Tru-Bru coffee pot, on which he was granted another
patent in 1920.

In 1912, John E. King, of Detroit, was gran
