Hello Peter,
I am not sure if this fits the bill, however a three stage steam piston engine appears to fit the bill. The steam exhaust of the first cylinder enters a cylinder of twice the diameter which then exhausts to a cylinder three times the size of the first. Each cylinder provides the same power, thereby the shaft is receiving three times more collective power for the same steam volume input.
Cheers Peter
