Abstract
A drive mechanism for linking the pistons of a heat engine to a rotating drive shaft includes a housing through which the drive shaft extends in rotatable fashion. Secured to the drive shaft within the housing is a main bevelled gear. A plurality of bevelled drive gears engage the main gear, each drive gear being secured to a gear shaft which extends through the exterior of the housing. Secured to the exterior end of each gear shaft is a gear wheel, which meshes with a similar, free-wheeling gear wheel. A pair of eccentric arms are secured to each pair of meshing gear wheels, their distal ends being secured to a block. A piston rod is also secured to the block, so that the reciprocal motion of the piston rod may be transferred through the eccentric arms and the gear wheels to the drive gear and the main gear.
