OLIVER CHILLED PLOW, 1910

Oliver workers began producing the patented "chilled plow" in Hamilton in 1910. The cutting blade of this plow was made of an extraordinarily durable "chilled" cast iron. The plant's foundries, forge and paint shops, assembly building and warehouses still stand on the waterfront directly east of Hillyard Street.

This was the first Hamilton project for the firm's architects, Pittsburgh-based Prack and Perrine (later Prack & Prack). They went on to design a number of other important factory buildings in the city including those of Standard Underground Cable, Canadian Westinghouse and Dofasco.

In 1919, International Harvester absorbed the Oliver plant and con-tinued operations under the name International Plow Company of Canada. In the mid-1920s, a number of the original Oliver buildings were converted to become Harvester's new Twine Mills.
