ABSTRACT:
A bakery machine adapted to shape dough pieces into thin pies suitable for pizzas. The machine includes upper and lower platens for supporting an upper pie-shaping die and a lower dough pan, and a crank mechanism for reciprocating both platens concurrently to cause the platens to move toward and away from each other, thereby effecting alternate engagement and disengagement of the die and pan. The crank mechanism includes crank rods terminating in pistons operating within hydraulic cylinders attached to the platens and moving therewith. Those compartments of the cylinders which are subjected to pressure when the platens move toward each other are filled with oil and are coupled by flexible lines to a compressible pressure chamber normally maintaining the oil in the compartments at a predetermined pressure level, such that when engagement takes place the pressurized oil is forced out of the compartments into the pressure chamber, and when disengagement takes place, the oil returns from the chamber to the compartments.
