Abstract:
An apparatus for increasing the mechanical efficiency of a piston-driven machine of the type having a housing containing at least one cylinder and piston, at least one piston connecting rod connected to the piston at one end, and a crankshaft having at least one crank and at least one crankpin, the apparatus being interconnected between the connecting rod and the crankpin and comprising:(a) a lever having a first end and a second end, the first end of the lever being pivotally connected to the housing adjacent to the cylinder to form a fulcrum point, said lever formed to pivotally connect to each piston connecting rod at a point between the first and second ends of the lever; (b) a bearing block movably positioned on the lever, the bearing block being moveable between first and second positions of the lever and operatively receiving the at least one crankpin therein; (c) wherein when the piston connecting rod and the crankpin of the machine are connected to the lever and the block and the piston is made to reciprocate: (i) during a first stroke of the piston, the bearing block is moved to a point where the crankpin is positioned between the fulcrum point of the lever and the connecting rod connection on the lever to deliver mechanical advantage to the crankpin; and (ii) on a second stroke of the piston, the bearing block is moved to a point where the connecting rod connection on the lever is between the fulcrum point of the lever and the crankpin to deliver mechanical advantage to the piston.
