Abstract
An adjustable eccentric assembly is mounted on a rotatable shaft and includes a first or drive collar having an arbor extending along the shaft and a second or guide collar mounted at the end of the arbor spaced from the drive collar. The drive collars have respective guide surfaces extending parallel to the axis of rotation of the shaft and a guide track is formed in the guide collar guide surface extending perpendicularly of the axis of rotation. A hub member is supported between the guide and drive collars and engages the guide track. Adjusting means serve to shift the hub member radially relative to the rotatable shaft to adjust the eccentricity of its rotation about the shaft. A throw member having a projecting link may be rotatably mounted on the hub member so that the eccentric rotation of the hub member imparts a reciprocating motion to the throw link. Locking means enable the adjustable eccentric assembly to be mounted in any rotational relation to the rotatable shaft so as to control the timing of the eccentric throw.
