    Abstract: A press unloader is provided for unloading parts from a press. The unloader comprises at least one arm. The arm is operative to rotate responsive to rotation of a shaft into and out of the press between an internal position between the dies of the press and an external position that is not between the dies of the press. The shaft may be driven by a drive linkage connected to an upper portion of the press and may rotate responsive to the up and down motion of the upper portion of the press. The arm may be comprised of lower and upper portions in pivoting connection with each other. A guide member is operative to cause the angle between the upper portion and lower portion of the at least one arm to become relatively wider at the internal position and to become relatively narrower at the external position.
