Page 274 - My attention was first directed in the year 1759 to the " subject of steam-engines, by the late Dr. Robison, then a " student in the University of Glasgow, and nearly of my " own age. He at that time threw out an idea of applying " the power of the steam-engine to the moving of wheel" carriages, and to other purposes, but the scheme was not " matured, and was soon abandoned on his going abroad.

Whenever, therefore, the piston is at the extremity of the stroke, and one of the legs is no longer of use to propel the engine forward, the other, immediately on the motion of the piston being changed, is ready, in its turn, to act as a fulcrum or abutment for the action of the moving power, to secure the continual progressive motion of the engine.
