Sometimes you have to fold an engine so it fits in the ship.
Back Acting steam engine offered a small profile solution and were in use in the 19th century, but mainly only for marine applications. By 1900 they were mostly extinct.
One interesting feature is the connecting rod ends are nearly the same on a Back Acting Steam engine.
