'Clockwise from right: A 1904 ad from the McLachlan Gasoline Engine Co. Ltd. of Toronto, Ontario. The engine was touted as a threshing engine, 20 HP, weighing 3,200 pounds; a 1912 ad for the Canadian engine from Canadian-American Gas & Gasoline Engine Co. Ltd. of Dunnville, Ontario, then a 2-year-old company. The engines were sold through Frost & Wood Co. Ltd., of Smith’s Falls, Ontario; a 1916 ad for a Chapman engine from Ontario Wind Engine & Pump Co. Ltd. The company claimed their cam box feature saved repair cost; and a 1913 ad from McKeough & Trotter Ltd. in Chatham, Ontario. '
'Above: A 1912 ad for the Barrie engine from The Canada Producer & Gas Engine Co. Ltd., Barrie, Ontario. According to C.H. Wendel in American Gasoline Engines Since 1872, 3, 4 and 5 HP engines such as the one seen in this ad filled the bill. “While all the quality features of larger models were retained, these were scaled down to specific requirements. The sideshaft design is evident, and an overflow type carburetor can be noted. Mounting the governor on the layshaft eliminated many extra parts, yet it was designed for extreme sensitivity,” Wendel writes. '
'Above: A Canadian Engines Ltd. ad from 1913. Like Canadian-American Gas & Gasoline Co. engines, these were also sold by Frost & Wood Co. Ltd. '
