Balanced Piston Engine.
Patent for a new and improved balanced-piston engine. This design "relates to that class of steam or other engines which are constructed with two pistons receiving the pressure in opposite directions, each connected with cranks set at opposite positions, whereby the strain occurs simultaneously in opposite directions upon the crank-shaft and balances the same within its bearings, and thus obviates great friction on the journals and thereby economizes power" (lines 7-15).
