Watt Beam Engine

This illustration shows the general arrangement of a
typical beam engine.  Beam engines were used in many factories to
drive machinery of all types and were sometimes built to enormous
proportions.  I have omitted the valve gear, as it was
substantially the same as the locomotive engine.It was important to restrict the motion of the piston and rod to a
straight line in order to reduce friction and wear on the upper
cylinder seal. The Watt linkage illustrated here is one of many contrivances for accomplishing this
linear motion.
