Abstract
In order to effectively and efficiently produce patties in a machine, particularly at a high rate of speed and while maintaining a consistent level as to the quality of production, a patty machine is disclosed which includes a casting, a ram, a mold plate, and a drive system. The casting has a cavity which is adapted to receive a material to be formed into a patty at an inlet located intermediate opposite ends thereof. The ram is reciprocably disposed within the cavity at a point upstream of the inlet, and the mold plate is reciprocably disposed relative to the cavity at a point downstream of the inlet. With this arrangement, the drive system imparts simultaneous reciprocating movement to the ram and the mold plate. The mold plate may cooperate with a knockout assembly where both the mold plate and the knockout assembly are driven through a hydraulic system in a coordinated fashion. The patties may be thus be discharged from the mold plate onto papers which are delivered one at a time for the purpose of forming a paper separated patty stack on a supporting surface. Additionally, the ram, mold plate, and casting are configured so that material is forced through a restricted passage, into a mold-filling chamber, and finally to a patty mold opening.
