The French meantime focused on coffee makers; and in 1827, Jacques Augustin Gandais, a manufacturer of plated jewelry in Paris, produced a really practicable pumping percolator. This machine had the ascending steam tube on the exterior. The same year, 1827, Nicholas Felix Durant, a manufacturer in Chalons-sur-Marne, was granted a French patent on a percolator employing for the first time an inner tube for spraying the boiling water over the ground coffee.
In 1828, Charles Parker, of Meriden, Conn., began work on the original Parker coffee mill, which later was to bring him fame and fortune.
The next year, 1829, the first French patent on a coffee mill was issued to Colaux & Cie. of Molsheim.
That same year, 1829, the Établissements Lauzaune, Paris, began to make hand-turned iron-cylinder coffee-roasting machines.
In 1831, David Selden was granted a patent in England for a coffee-grinding mill having cones of cast-iron.
The first Parker coffee-grinder patent for a household coffee and spice mill was issued in the United States in 1832 to Edmund Parker and Herman M. White of Meriden, Conn. The Charles Parker Company's business was founded the same year. In 1832 and 1833, United States patents were issued to Ammi Clark, of Berlin, Conn., also on improved coffee and spice mills for home use.
Amos Ransom, Hartford, Conn., was granted a United States patent on a coffee roaster in 1833.
The English began exporting coffee-roasting and coffee-grinding machinery to the United States in 1833–34.
