Stirling (of Kilmarnock)
Extract from Steam Locomotion on Common Roads by William Fletcher. Published 1891.
Mr. Stirling, of Kilmarnock, in 1859, designed a road steamer, in which several neat devices were embodied. All the five travelling wheels were mounted upon springs. A single wheel was used as a driver, and an adjustable arrangement used for causing more or less weight to rest upon this wheel. The leading and trailing wheels were arranged to swivel in concert, in opposite directions, by means of right and left hand worms and worm wheels, whereby a double efTect was obtained, and the carriage was made to move in a curve of much less radius than is obtainable with the ordinary steering arrangements.
