Abstract
Stamping and forming machine having reciprocable rams which move towards and away from each other between open and closed positions having adjustable eccentrics for adjusting the strokes of the rams. The rams are reciprocated by oscillating levers which are coupled to a power shaft by eccentric assemblies. Each eccentric assembly has a fixed eccentric on the power shaft and an adjustable eccentric which is rotatable, for adjustment purposes, with respect to the fixed eccentric thereby to change the stroke of the associated ram assembly.
