Patent ID: 8720410

Claim:
In an internal combustion engine having a crankshaft with a crank pin and performing a power stroke during an operational cycle, a piston crankshaft linkage, comprising in combination: a connecting rod having two ends, the distal end rotatably linked with the crank pin, the proximal end further having a circular upper off-centered opening and a circular lower off-centered opening positioned beneath and in the opposite half of the connecting rod from the upper off-centered opening; a slide connecting pin inserted through the lower off-centered opening of the connecting rod, the slide connecting pin rotatably fastened at both ends by two identical slide members, each slide member further having two side slide panels; a hollow follower having two identical grooves, each groove further having two side walls, four identical elongated follower inserts disposed fittingly on each side wall of the grooves, each follower insert further having an exposed flat panel dimensioned matchingly to the slide panels of the slide members, the grooves further dimensioned to fittingly receive the connecting rod such that each of the two side slide panels of the two slide members coupled slidably with its corresponding exposed flat panel of the follower inserts, such that the connecting rod slides and swivels freely within the follower during the operation cycle; a linking member having an upper and a lower extension, the lower extension connected pivotally to the upper off-centered opening of the connecting rod by mechanical means; a piston having a first wrist pin for pivotally connecting the piston to the upper extension of the linking member, the wrist pin inserted through the piston and the upper extension and having two exposed ends; and two connecting members each having two extensions, the upper extensions connected rotatably to the exposed ends of the wrist pin, the lower extensions connected rotatably to two exterior sides of the follower, the connecting members fastened the piston and the follower rigidly such that the piston and the follower move vertically in unison during the operation cycle.
