Another very RARE find - a data DVD republication for the 50 page George White Thresher Catalog of 1912. Lots of great information and beautiful graphics of these rare machines.
The 1889 threshing machine built by George White of London, Ontario, contained features common to other North American threshers. One interesting feature of this machine is that White specified an entirely metal construction, with "no woodwork being used as heretofore in machines of this class." In this regard, he seems to have been ahead of his time. Metal parts were more durable than wood and could better withstand the significant wear and tear encountered in high-volume harvests. However, it is likely that wood was used for the machine's frame and side panels (not mentioned in the patent), as all-metal machines were first introduced in 1904 by farm machine magnate J.I. Case of Wisconsin. Fittingly, White was one of the first Canadian manufactures to follow suit with his own all-metal machine.
BONUS: Included is also the 1927 George White Steel Threshing Machine catalog. 34 pages, provides
