1910.

Isaacson Engine Company of Leeds

Aero-engine.

1910 Rupert John Isaacson employed Albert Edward Charlton, 22, who had been with Isaacson's previous firm, and together they produced their first radial (as opposed to rotary) engine, which was ordered by Claude Grahame-White. It quickly became apparent that it would be too heavy, so Isaacson designed a Mk 2 version of 40 HP, with 7 cylinders. A novel feature was the use of gearing to give a propellor speed of half the crankshaft speed. After testing and modification, including a change from cast iron to steel cylinders, the engine was fitted to the Blackburn No. 2 monoplane.

1910 May. Detailed letter from R. J. Isaacson regarding the engine.[1]
