1 Goucher, John
SUBJECT AREA: Agricultural and food technology[br]b. c.1831 Woodsetts, Yorkshire, Englandd. unknown[br]English engineer and inventor of the rubbing bars used on threshing machines and combine harvesters.[br]John Goucher was the son of a Yorkshire farmer who began his employed life as a carpenter. In 1851, at the age of 20, he was living on the farm of his father and employing four labourers. He developed and patented a means of wrapping wire around the individual bars of a threshing machine drum in such a way that grooves were formed in them. These grooves allowed the threshed grain to pass through without being crushed or otherwise damaged.[br]BibliographyOther patents credited to him range from devices for the propelling of ships in 1854, beaters for threshing machines in 1848, 1856, and again in 1861, stacking corn and other crops in the same year, improvements to steam boilers in 1863, for preserving life in water in 1867, threshing machines in 1873 and 1874, steam engines in 1884, and threshing machines in 1885.AP
