Bramah Joseph Diplock
Bramah Joseph Diplock was an English inventor who invented the pedrail wheel in 1903.[1][2] and the pedrail chaintrack, a type of caterpillar track, in 1910.
Pedrail Transport Company
Diplock founded the Pedrail Transport Company of Fulham which was, before World War I, the only British company to manufacture "caterpillar" continuous tracks.[3] A demonstration of the system's ability to support a large load for trench warfare was made on 16 February 1915 to Winston Churchill, and may have been influential in the development of the tank.[4]
