Abstract
A food packing machine employing a piston for compressing and preparing a cake of food for canning. The piston rides reciprocally in a carrier which is cam driven toward and away from a cake-forming cavity, wherein the piston acts against food particles. Operation of the carrier and piston, as the latter moves initially into the cavity's entrance, is characterized by nonyieldable biasing, or driving, of the piston into the cavity. Immediately thereafter, a spring which is interposed between the carrier and piston promotes continued, but now yieldable, drive of the piston into the cavity.
