... the radius rod with it without producing any motion whatever at the front end
connection of the radius rod with the combination lever . To make this possible
the forward curve of the link must have a radius equal to the length of the radius
rod .

not give any motion to the link - block , radius rod , nor valve , but the cross - head
would , by means of the combination lever , give the valve a short travel that
would be equal to twice the distance of lap plus lead . The connections from

So , if the full travel of the valve and the full throw of the eccentric are to be
maintained as equal distances — and they are — then the valve in Fig . 6
overtravels in each direction ; we have not allowed for that and the question is ,

So , let's leave the throw of the eccentric and the required full travel of the valve
remain equal , as they should be , and now extend an arm down from the lower
end of the link and connect the eccentric rod to its lowest point instead of to the
link ...
