A potato dough extruder incorporating an incremental manually operable pressure apparatus for manually extruding potato dough through an extrusion die which forms the dough into the shape of french fried potatoes, in which the potato dough is contained in a cylindrical container and pressure is applied to a pressure piston in the cylinder through a smooth cylindrical pressure shaft, the incremental pressure apparatus incorporating a ring-like gripping device which is slidable up and down the shaft so long as the ring is located in a plane substantially normal to the shaft, and in which the ring gripping device is tiltable out of such a plane and grasps the shaft at any point along its length thereby doing away with teeth, sprockets, and notched gripping devices and at the same time incorporating the improvement that as soon as the tilting force applied to the ring gripping device is released the pressure on the pressure shaft is also released. This particular improvement eliminates the tendency for the extrusion of the dough to continue after a single serving of french fries has been obtained from the machine.
