Movement 136
AnimatedOriginal 

136. A cam-wheel—of which a side view is shown—has its rim formed into teeth, or made of any profile form desired. The rod to the right is made to press constantly against the teeth or edge of the rim. On turning the wheel, alternate rectilinear motion is communicated to the rod. The character of this motion may be varied by altering the shape of the teeth or profile of the edge of the rim of the wheel.
