Abstract
The invention is a reciprocating mechanism for piston driven internal and external combustion engines. The design presented consists of an intra-articulate connecting rod system operating in conjunction with a compound crankshaft. The advantage of this system over the ordinary reciprocating mechanism employed in other engine systems, is seen to be in the reduction of piston speed during the initial expansion process thus allowing higher combustion pressures to develope at more effective crank angles past the top neutral center position of shaft rotation.
Claims2
A crankshaft comprising a plurality of longitudinally aligned and longitudinally spaced mainshafts having arms fixed on the adjacent ends of said mainshafts lateral crankpins projecting from each said arm and attached to a common central crankpin having an axial centerline parallel with said lateral crankpins but whose axial center is displaced from that of said lateral crankpins, lateral connecting rods rotatively mounted on said lateral crankpins at one end and pivotally attached to a central connecting rod at the other end said central connecting rod having a journal at one end for pivotally mounting a piston and being rotatively attached to a link at the other end, said link being rotatively mounted on said common central crankpin.
