ABSTRACT OF THE DISCLOSURE Oscillatory motion apparatus has a first recipro- cating rod oriented generally perpendicularly with respect to a second reciprocating rod. A first trammel gear is pivotally secured to the first and second rods. Reciproca- tion of the rods produces responsive rotation of the trammel gear. An output gear may be rotated responsive to rotation of the trammel gear. The invention may be embodied in an engine block and two or more pairs of opposed cylinders each containing pistons adapted for reciprocation therein is provided. The rods, which may be connecting rods, connect pairs of opposed pistons. The connecting rods are preferably oriented generally perpendicularly with respect to each other. The connecting rods are rotatably connected to the trammel gear. Reciprocation of the pistons results in rotation of the trammel gear which is operatively associated with an output gear to produce rotary output. In one embodiment a bifurcated connecting rod permits two trammel gears to be employed with corresponding use of two output gears. In another embodiment, a planetary arrangement is provided. The engine is compact, lightweight and has a very high horsepower to weight ratio.
