Abstract
Reciprocating motion can be converted to rotary motion through a crankshaft and a connecting rod. In a connecting rod that is primarily in compression, two opposing connecting rods can be coupled to a single journal. Two bearing shell portions are placed over the journal with a pushrod placed over each bearing shell portion. The pushrods are normally in compression. To overcome the potentiality of the pushrods briefly being in tension, retainers can be coupled to the pushrods. Because both pushrods are coupled in-line, the width of the journal that can accommodate these pushrods is shorter than for a journal on which the two pushrods are side by side. The crankshaft can be shorter, stronger, and lighter weight.
