In starting the engine , if we should pinch the wheel backward , the eccentric
would pull the valve backward also , and steam would be admitted to the forward
end of the cylinder , pushing the piston back in spite of our efforts , and it would

This would now give the proper motion to the valve for running the engine
backward , and of course the direction is fixed : it can only run that way . Besides
having no power to turn the wheel when the main - pin is on the dead - centre ...
