ABSTRACT:
A manually operable extrusion press, especially one for producing pasta from a mass of dough, comprises a cylinder with a piston whose piston rod is embraced by flexible prongs of an operating lever that are pivoted to the top of the cylinder opposite a bottom nozzle provided with one or more shaping apertures. The sides of the piston rod facing the prongs have serrations coacting with driving pawls disposed on the inner prong surfaces which are outwardly yieldable during an upswing and engage the serrations on a downswing of the lever, the serrations being also engageable by retaining pawls on the cylinder serving as backstops. A 90.degree. rotation of the piston rod about its axis confronts both pairs of pawls with flat rod surfaces to enable free upward or downward motion of the piston. The entire assembly preferably consists of plastic material such as glass-fiber-reinforced polyamide.
