The return crank must be shortened to secure lead . And this proves that with any
kind of valve motion where but one eccentric is used , lead cannot be
satisfactorily derived from advancing or receding the position of that eccentric on
the main ...

... this change has shortened the swing of the link and the carry of the link - block ,
and on some engines this foot of the link is so long that the reduction in link -
block travel amounts to a great deal , but it only affects the long motion of the

The only part capable of variation in length is the eccentric rod which connects
the return crank with the link ; this rod may be slightly lengthened or shortened ,
to correct errors in the location of the link centre , from centre of the driving axle ...
