Cruciform engine
This patent describes a cruciform reciprocating engine including a crank case, an elongated crank shaft with opposite ends rotatably supported by the case on a central turning axis and an elongated central crank pin within the case on a second axis parallel with and spaced radially outward from the turning axis, two pair of elongated cylinders with radially disposed inner and outer ends on radial axes extending radially of and intersecting the turning axis, the inner ends of the cylinders are secured to the case, the radial longitudinal axis of each pair of cylinders is at right angle to the radial longitudinal axis of the other pair of cylinders. The radial longitudinal axes are spaced axially of the crank pin, an elongated piston unit is engaged with and extends between the cylinders of each pair of cylinders, each piston unit includes an elongate yoke on a radial plane parallel with the radial longitudinal axis and normal to the turning axis. The yoke has a bearing opening intermediate its ends on an axis parallel with and spaced radially from the turning axis and from the crank pin. The yoke has opposite ends disposed toward related cylinders, an elongate cylindrical piston with radially disposed inner and outer ends is secured to each end of the yoke and is shiftably engaged in the cylinder related thereto, an elongate twin eccentric disc driver is drivingly engaged with and between the crank pin and the yokes. The driver includes a pair of axially spaced cylindrical discs, each disc is rotatably engaged in the bearing opening in a related yoke, the central axis of the discs are on spaced parallel third axes spaced radially.
