S been given that is desired. The valve must be tried by turning the
engine round to see that it is right at both centres, for going ahead
and also for going astern. In some examples of the link motion, one of
the eccentric rods is made a little longer than the other, and the
position of the point of suspension or point of support powerfully
influences the action of the link in certain cases, especially if the
link and this point are not in the same vertical line. To reconcile all
the conditions proper to the satisfactory operation of the valve in the
construction of the link motion, is a problem requiring a good deal of
attention and care for its satisfactory solution; and to make sure that
this result is attained, the engine must be turned round a sufficient
number of times to enable us to ascertain if the valve occupies the
desired position, both
