Simplex Engine Co of East Street, Coventry
of Payne's Lane, Coventry (1910)
Maker of engines
1903 The company was started in 1903 as Lee, Stroyer and Co, but two years later following the departure of Stroyer, was relocated to Paynes Lane, Coventry, and renamed to Coventry-Simplex by Henry Pelham Lee who saw a need for competition in the piston engine market.
An early user was GWK, who produced over 1,000 light cars with Coventry-Simplex two-cylinder engines between 1911 and 1915. Just before World War I a Coventry-Simplex engine was used by Lionel Martin to power the first Aston Martin car. Ernest Shackleton selected Coventry-Simplex to power the tractors that were to be used in his Imperial Trans-Antarctic Expedition of 1914.
