Abstract
An internal combustion engine having a plurality of pairs of pistons, each piston having a fixed connecting rod operating a ratchet on the crankshaft through a crank and pawls. The ratchet for each piston is coplanar with the connecting rod, and the two pistons of each pair are interconnected by a rocker arm for alternate piston return. Each pair of interconnected pistons operates independently of the other pairs so that if any pair is stopped through damage, the other pairs will not be affected.
Claims8
In an internal combustion engine, a plurality of pistons, each piston having a connecting rod fixed thereto, a rotatably mounted crankshaft, a plurality of one-way ratchets on said crankshaft, each ratchet being in the plane of a connecting rod, a pawl arm for each piston rotatably carried by said crankshaft, pawls carried by each pawl arm and engageable with said ratchet, and a pin-and-slot connection between each pawl arm and its connecting rod.
In an internal combustion engine, at least one pair of side-by-side pistons with parallel movement, connecting rods secured to said pistons, a rotatable crankshaft, one-way ratchets on said crankshaft in the planes of said connecting rods, pawl arms rotatably carried by said crankshaft, pawls carried by said pawl arms and engageable with the ratchets, and means for moving each piston in an upstroke when the other piston moves in a downstroke, said last-mentioned means comprising a rocker arm having a fixed central pivot disposed between said connecting rods, and slots in said connecting rods, the outer ends of said arm being disposed within said slots.
