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.

Abstract: A sheet applicator for applying individual thin, flexible sheets of paper or similar material to a series of relatively thick, flat articles (e.g., hamburger patties) as those articles fall along a defined discharge path terminating at a stacking position, comprising a shuttle with vacuum grippers for transferring each flexible sheet from a transfer position to an application position on the article discharge path, where one of the articles engages the sheet and carries it to the end of the discharge path. The grippers engage at least three peripheral points around the edges of the sheet; the falling article pulls the sheet from the gripper, falling through a central opening in the shuttle. The carriage then returns for the next sheet. A single-sheet feeder applies the sheets to the shuttle in registry with the vacuum grippers.
