Early English Coffee Peeler
Largely used in India and Ceylon
James Henry Thompson, of Hoboken, and John Lidgerwood were granted, in 1864, an English patent on a coffee-hulling machine. William Van Vleek Lidgerwood, American chargé d'affaires at Rio de Janeiro, was granted an English patent on a coffee hulling and cleaning machine in 1866. The name Lidgerwood has long been familiar to coffee planters. The Lidgerwood Manufacturing Co., Ltd., has its headquarters in London, with factory in Glasgow. Branch offices are maintained at Rio de Janeiro, Campinas, and in other cities in coffee-growing countries.
Probably the name most familiar to coffee men in connection with plantation methods is Guardiola. It first appears in the chronological record in 1872, when J. Guardiola, of Chocola, Guatemala, was granted several United States patents on machines for pulping and drying coffee. Since then, "Guardiola" has come to mean a definite type of rotary drying machine that—after the original patent expired—was manufactured by practically all the leading makers of plantation machinery. José Guardiola obtained additional United States patents on coffee hullers in 1886.
Group of English Cylinder Coffee-Pulping Machines
William Van Vleek Lidgerwood, Morristown, N.J., was granted an English patent on an improved coffee pulper in 1875.
Several important cleaning and grading machinery patents were granted by the United States (1876–1878) to Henry B. Stevens, who assigned them to the Geo. L. Squier Manufacturing Co., Buffalo, N.Y. One of them was on a separator, in which the coffee beans were discharged from the hopper in a thin stream upon an endless carrier, or apron, arranged at such an inclination that the round beans would roll by force of gravity down the apron, while the flat beans would be carried to the top.
