This patent describes a reciprocating piston engine wherein there is included the combination of one or more pistons individually reciprocatably mounted each within a cylinder, an intake valve located within a cylinder through which fuel and air can be admitted into the cylinder, compressed and the fuel burned to drive a piston during a power stroke, an exhaust valve located within a cylinder through which burned fuel can be exhausted by movement of a piston to expell the burned gases during an exhaust stroke, a piston having a crown side and a side opposite the crown side to which a piston shaft is attached, the crown side of the piston facing into the cylinder wherein the intake and exhaust valves are located, an elongated roller gear to which the piston shaft is attached, the elongated roller gear is open centered and has an inside face thereof provided with a continuous array of teeth, a drive shaft, a roller gear pinion operatively engaged with the drive shaft, rotation of which produces rotation of the drive shaft, the roller gear pinion being provided with a continuous array of teeth for continuous meshing engagement with the teeth on the inside face of the elongated roller gear, movement of a piston acting through a piston shaft and elongated roller gear producing rotation of the drive shaft via action upon roller gear pinion, the impovement comprising, in the combination, a pair of rails, one each of which is disposed on opposite sides of the teeth of the elongated roller gear, a pair of rollers, one each of which is disposed on opposite sides adjacent and parallel to the teeth of roller gear pinion, the rollers of the roller gear pinion contacting and rolling along the rails of the elongated roller gear to maintain a proper relationship and root clearance between the meshing teeth of an elongated roller gear and a roller gear pinion for effecting the continuous rolling and meshing engagement.
