Dorman Engineering Co was situated in Northampton and built D.E.C. Engines. The firm was established around 1899 by Thomas Phipps Dorman and used patents held by Horace Walter Dover, who left the company to form his own selling motor and cycling accessories. He was very successful.
The Whirlwind name was better known in the cycling trade, and many were sold to leading cyclists of the day. Dover was very inventive and later formed Dover Ltd which marketed many of his patents. His wife too was highly regarded and in 1920 was decorated by the King for her services.
