Connecting rod for horizontally opposed compressor

A horizontally opposed engine comprising crankshaft and at least two diametrically opposed cylinders, each opposed cylinder having a piston and a single connecting rod cooperatively associated with the piston and the crankshaft, one of the connecting rods having a crankshaft bearing portion on one end and a wrist pin bearing portion on the other end, the other connecting rod having two spaced apart legs with a crankshaft bearing portion disposed on one end of each of the legs, the other end of the legs coming together to form a wrist pin bearing portion, the spacing between the legs being sufficient to allow a portion of the crankshaft cooperatively associated with the crankshaft bearing portion of the one connecting rod to rotate between the legs of the other connecting rod, whereby the reciprocating mass forces associated with the diametrically opposing cylinders are generally equal and opposite and cancel one another producing a smoother running engine.
