Abstract
A mechanical press having a variable drive arrangement. The press includes a main gear which drives a crankshaft. The drive altering mechanism includes a two piece crown with the main gear connected to the upper crown and the crankshaft connected to the lower crown. Movement of one piece of the crown relative to the other varies the distance between the crankshaft center line and the main gear center line, thereby altering the drive mechanism of the mechanical press and the velocity curve of the press slide.
