[SEL] CrossHead

[Ron Frost, Kersey, PA]

Hi Ed,
A crosshead is a sliding component that is located between the crankshaft and the piston. There is a wrist pin in it that connects the crank to the crosshead, then a straight round rod screws into the top of it and runs to the underside of the piston. Crossheads are mainly used in double acting  steam engines and compressors. The usage of the crosshead and straight solid round connection rod allows a good sealing area and the lower or underside of the piston can then be used as power or compresson.  The only internal combustion engine I'm aware of is the Mery 6 cycle engine.
How's the 2 cyl Briggs comming along?
