Champion stationary petrol engine

  • 1935-1940
The Champion was a very successful small petrol engine made by a large Sydney company. With hopper cooling and a fuel tank mounted between the skids, and weighing only 240 pounds (109 kg), it was easy to mount on a wheeled transport and so become a self-contained mobile source of power. Engines of this type were used in rural areas for driving chaffcutters, small saw benches, pumps and orchard sprayers. This particular engine was used to drive a concrete mixer, which was a typical application …

Physical Description

Petrol engine, horizontal stationary, 'Champion', cast iron / steel / paint, manufactured by Westinghouse Rosebery Pty Ltd, Rosebery, NSW, Australia, 1935-1940

This is a type 2A four-stroke water-cooled engine with a single horizontal cylinder. It develops 2 horsepower (1.5 kilowatts) at 450 rpm. The engine is painted green, and two starting handles, a drive chain and a gear wheel are included in the acquisition.

The engine cylinder has bore 3.5 inches (89 mm) and stroke 5 inches (127 mm). It is surrounded by an open cooling-water hopper of rectangular cross-section. The connecting rod protrudes from this box-like casting and drives the crankshaft, which is normally protected by a metal shield. The engine has twin flywheels with projecting shaft ends to accommodate a variety of power take-off means.

A chain-driven Fellows type EA1 magneto energises the spark plug, which is located in the cylinder head. The inlet valve is actuated automatically on the suction stroke, and the exhaust valve is opened by a cam-actuated push rod and rocker. The push rod can be seen running the length of the engine. The products of combustion are exhausted through a mushroom-shaped muffler. The speed of the engine is regulated by a hit-and-miss centrifugal governor, which holds the exhaust valve open when the engine speed exceeds the set point.

The manufacturer claimed that the engine could run all day on a gallon (3.78 litres) of petrol.


On a brass plate on the engine: CHAMPION PATENT OIL ENGINE / No 1975 450 RPM 2HP. On the magneto: FELLOWS TYPE EA1 / BRITISH MADE No 9742 / LONDON

The engine was designed by Fuller & Johnson of Madison, Wisconsin, and manufactured by Westinghouse Rosebery Pty Ltd of Rosebery, NSW. The partnership between Rosebery Engine Works and the Westinghouse Corporation dates from 1935. The company was taken over by EMAIL in 1940. The engine appears to have been manufactured between 1935 and 1940.

The firm of Fuller & Johnson commenced about 1880 as a dealership in farm implements. M E Fuller (1821-1919) was born in Little Falls NY and moved to Madison, Wisconsin, in 1858. He became involved in the farm implement business and became a partner in Fuller-Williams & Co. When John Anders Johnson (1832-1901), a Norwegian migrant, joined the firm in 1873, it became known as Johnson, Fuller & Co. In 1882 the name was changed to Fuller & Johnson & Co and Johnson became president. In 1889 he established the Gisholt Machine Co to make machine tools and is credited with the invention of the turret lathe.

Fuller & Johnson began making engines in 1902, with the most widely used being the farm pumper, which was manufactured between 1909 and 1952. Between 1913 and 1925 the company sold 56,000 hopper-cooled Model N petrol engines, and numerous Model K kerosene engines. Late in the 1920s the firm experienced a drop in sales, probably due to the electricity grid expanding into farming areas, and the company moved to the manufacture of more powerful engines for the construction industry. The depression of the 1930s caused the closure of the company in 1933.

Mr A B Armstrong began an engineering merchant business at 9 Market St Sydney in 1849. The business was expanded in 1858 by purchasing a ship chandler business from Mr J Carr. Mr Armstrong's daughter Sarah married W S Buzacott in 1862, and he was made a partner in the firm in 1864 and managing director in 1877.

In 1900 W V Buzacott, who had trained as an electrical engineer, went to the USA to gather information from the Hercules Engine Works and obtain the Australian agency for the company. He brought back three oil engines and began to manufacture engines. In 1902 the firm became Buzacott & Co Ltd. It grew to become a very well known manufacturer and supplier of engines and agricultural equipment such as fences, gates, pumps, kerosene engines, wool presses, elevators, corn crushers and chaffcutters. Because of the group's growth, new premises for manufacturing were built at Dunning Ave, Rosebery, Sydney.

In the 1920s, Alan E Buzacott (1899-1983) completed a Bachelor of Engineering degree, became a director of Henry Lane (Australia) Ltd, and was appointed chief engineer for Rosebery Engine Works Ltd, the engine and pump manufacturing division of Buzacott & Co Ltd.

In 1926, on account of the high tariff set by the Australian government on import of American engines, Rosebery Engine Works began to make versions of the popular Fuller & Johnson engine. The Rosebery engine was almost the same as the Fuller & Johnson except that a rotary magneto was used with a direct gear driven from the driving pinion on the crankshaft, and mounted on a flat on the top side of the crankshaft main bearing. Rosebery engines were fitted with Fellows EA1, ML.CMA, BTH, M1F2 and Bosch and Wico magnetos.

In 1935, after a long association with the Westinghouse Corporation, Rosebery Engine Works signed a new agreement giving it the right to manufacture and sell nearly all products of the Westinghouse company. It changed its name to Westinghouse Rosebery Ltd and then to Westinghouse Sales and Rosebery Ltd. In 1940 the company ran into financial and management problems and was taken over by the EMAIL group.

The Rosebery Engine Works sold engines under the names Buzacott, Rosebery, Champion, New Record, Lightning, Goldsborough, Moffat-Virtue and Waugh & Josephson. It is thought that this arrangement continued from 1926 until 1950.



The engine was acquired second-hand by Mr John Smith, who used it for a short time to power a large concrete mixer. The donor, Mr W R Mackay of Hurstville Grove in Sydney, obtained it from Mr Smith around 1977, but he did not use it.
