Patent drawing for the Weatherholt stationary engine. The piston is fixed, The cylinder reciprocates...And note where the valves are located.

Easy way to avoid that Bob...Use pistons as valves.

Does that make it a 2x4 stroke?

A Bonneville Lakester please barman.
Certainly sir; a lick of salt, a sip of gas and a twist of Lemming. More Lemming sir?
Just a squeeze.

WW II diesel submarine engines were opposed piston - less noise for the bad guys' sonar to hear.

Under the heading of:
You can make ANYTHING work, given enough time & development money . . . . .
A/ Probably ok for some sort of "Johnny Popper" stationary power source.
2/ Overly small valves and "longish", tortuous ports prevent achievement of "high efficiency".
d/ Moving cylinder as higher mass than moving piston, and since F = m*a, severely limits rpm potential.
z/ High rpm use might dictate a "cylinder return spring" taken from a railroad boxcar suspension . . . .
Lots of interesting ideas floating around from 1903. Might there be a working example in a museum somewhere?
