Walker's Original Disk Pulper, 1860
Much favored in Ceylon and India
John Walker was granted (1860) an English patent on a disk pulper in which the copper pulping surface was punched, or knobbed, by a blind punch that raised rows of oval knobs but did not pierce the sheet, and so left no sharp edges. During Ceylon's fifty years of coffee production, the Walker machines played an important part in the industry. They are still manufactured by Walker, Sons & Co., Ltd., of Colombo, and are sold to other producing countries.
Alexius Van Gulpen began the manufacture of a green-coffee-grading machine at Emmerich, Germany, in 1860.
Following Newell's United States patents of 1857–59, sixteen other patents were issued on various types of coffee-cleaning machines, some designed for plantation use, and some for treating the beans on arrival in the consuming countries.
