341. “Grasshopper” beam engine. The beam is attached at one end to a rocking-pillar, A, and the shaft arranged as near to the cylinder as the crank will work. B is the radius-bar of the parallel motion.


Notes:

The radius-bar in Brown’s illustration would not appear to generate a parallel motion. In our animation we have moved its right joint to the center of the beam to correct this.
