Lead is given in order that steam may be admitted between the piston and the
cylinder head , toward the completion of the stroke , as a means of cushioning the
piston and thereby tempering the sudden reversion of its motion ; the same effect

So that valve - advance , or lead , will be the first requirement in remodelling the
engine of Fig . 2 . In these reference plates we are using a “ return crank ”
eccentric , which shows the exact point at which the valve gear receives its initial
motion ...
