The Jacobs Aircraft Engine Company was an American aircraft engine manufacturer that existed from 1926 to 1956.
History [ edit ]
Early years [ edit ]
The Jacobs Aircraft Engine Company was formed in 1926 in Philadelphia .[1] [failed verification Later the company moved to Pottstown, Pennsylvania [2]
Early engines [ edit ]

An early product was the 1931 L-3 , a 190.4 cu in (3,120 cc ) 51 hp (38 kW ) three-cylinder air-cooled radial engine . Only 44 were built.
By 1933 , Jacobs had developed its most famous engine, the L-4 seven-cylinder air-cooled radial, with a power rating of 225 hp (168 kW ) displacement of 757.7 cu in (12,416 cc ). It was better known as by its military designation, R-755 .[3] aluminum alloy pistons , sodium -filled exhaust valves , and magnesium alloy crankcases .
The L-4 was used mostly on the Cessna Bobcat , Cessna 195 , and Stearman Kaydet .
Due to the tendency of the L-4 engine to vibrate heavily at low rpm, it was given the nicknames Shakin' Jake and Shakey Jake .[4]
Later models [ edit ]
Later developments included the 285 hp L-5 or R-830, and 330 hp L-6 or R-915.
Postwar [ edit ]
Jacobs was acquired by Republic Industries in 1945, which was in turn acquired by Barium Steel Corporation in 1946. However in 1947, the company was sold back to Albert Jacobs. Jacobs Aircraft Engines went into default in 1950 and was again sold back to Republic.[5] [6] [7]
Applications [ edit ]

Jacobs engines were fitted to many US-built aircraft of the inter-war period, including several Waco models. They were in use in 26 different countries including in Canada, where 330 horsepower L6-MB engines were used to power the Royal Canadian Air Force's Avro Anson Mk. II aircraft.[8] [8] World War II military production contracts.[9]
