It was soonfound that locomotives, adapted for gentlecurves, were ill suited for the exigencies of Americanrailroads, where curves of as small a radius as 200feet were sometimes employed, ilr. Peter Coopei-,since so well and widely known, devised an enginewhich solved the difficulty. This was in 1829. The second locomotive built in the United Statesfor actual service was for the .South Carolina Lail-road, ami niaile its tii-st regular trip in March, Tlie London Engineer describes an engine builtfor the Mt. Cenis Railway as having four drivers andfour horizontal wheels, which latter gnisp betweenthem a central rail with an amount of pressure regu-lated by springs, which are controlled by bars bear- Fig. 298;. liahlwin Locotnotii-e (Central Longitudinal Section). 29S8. ing upon them, and adjusted liy means of ii shaftextending across the engine and furnished with rightand left handed screws. This shaft carries on its enda worm-wheel, gearing into a worm connected witha hand-wheel on the foot-plate, by which the press-ure is regulated. This maj- be increased to 24 tons,6 on each wheel.
