“ But the appellees' machine has a raking apparatus differently organized. In it each arm moves independently of every other arm, the arms are not coupled in pairs, and each does its work without reference to the movement of any other. Therefore, it is unnecessary to raise the supporting porting point of the rake-amrs to any considerable height, or to carry it over to a location between the drive-wheels, and in the appellees' machine the pivot on which the rakes revolve is at a considerable distance towards the outer shoe and is not all between the drive-wheels. ”

“ Now, the arms of the raking apparatus are diametrical arms, the centers of which are axes mounted on a horizontal head, which head is so fastened on a vertical shaft that, the opposite ends of the arms being inclined to the axis of rotation, one end of one arm will descend and sweep across the platform, while the other will be carried in an exactly opposite direction, with its rake teeth turned up, while the teeth of its opposite arm are turned down. ”

“ As to the yielding belt-tightener of the appellant, which is the subject of claim 3 of the original patent and is an element in claim 16 of the reissue, the appellees' machine does not employ any device which performs the function of tightening a belt. ”
