Abstract

A patty forming machine includes a mechanical compartment having a front wall and surrounding a reciprocating device, a reciprocating mold plate having cavities for forming patties, and a reciprocating knock-out device for knocking the patties from the mold plate. The knock-out device includes vertically reciprocating knock-out rods, knock-out bar arms connected to the knock-out rods, a bar connected to the knock-out bar arms, and a plurality of cups connected to the bar. The knock-out rods are guided both above and below the knock-out bar arms for vertical reciprocating movement. The knock-out rods are connected together by a tie rod and clamp blocks located at opposite ends of the tie bar. The knock-out rods are driven into vertical reciprocation by knock-out arms which are driven to pivot by rotating cams. Located adjacent to each of the cams is an oil reservoir which is substantially sealed except for being penetrated by two wicks, one of the wicks being used to transport oil to the pivotal connection of the respective knock-out arm, and respective other of the wicks arranged to transport oil to the cam surface which drives the knock-out arm.
