Internal combustion engine without connecting rods
This patent describes a reciprocating, multicylinder, internal combustion engine having an axially rotating power output crankshaft, the combination of: (a) combustion chambers in side-by-side parallel arrangement, each chamber containing first means to admit a combustible fuel/air mixture and to exhaust the fumes of combustion; (b) a separate cylinder having an open end and a closed end forming part of each combustion chamber and a piston working independently in each cylinder and arranged to travel toward the closed end to compress the mixture and be driven in a power stroke toward the open end as a result of the burning of the mixture; (c) a carrier member and means to attach the member to a pair of adjacent pistons for interconnecting them to reciprocate in unison in their respective cylinders; and, (d) a guide member, pivotally attached to an offset throw formed in the output crankshaft connected to the carrier member in sliding engagement therewith to convert the reciprocating motion of the pistons into rotary motion of the crankshaft through motion in a plane lying transverse to the axis of the crankshaft.
