Frame for a patty-forming apparatus
DCFirst Claim
1. A frame structure for a reciprocating mold plate type food product forming apparatus, wherein the forming apparatus comprises at least one hydraulically driven pump that includes a pump piston driven into a pump cylinder by a driving mechanism, and a reciprocating drive and connected to a mold plate, comprisinga frame portion supporting the reciprocating mold plate;
- a base structure;
a first angular strut extending obliquely from a rear location on said base structure forward and upwardly to an elevated central location and fixed to said frame portion;
a second angular strut extending obliquely from a forward location on said base structure rearward and upwardly to said elevated central location and fixed to said frame portion, andsaid first and second struts being sufficiently rigid to withstand reciprocal forces caused by said reciprocating mold plate.

Abstract
A frame structure is provided for a reciprocating mold plate type food product forming apparatus. The frame structure includes an angular strut configuration for resisting horizontal reciprocating forces caused by the reciprocating mold plate and associated drive, and a tie rod arrangement for resisting separation-reaction forces caused by food product compression by a plunger in a pump cylinder of a food product pump. A base plate supports the frame structure. A first angular strut extends from a rear location forwardly and upwardly to an elevated central location and is fixed to the frame portion. A second angular strut extends from a forward location rearward and upwardly to the elevated central location and is fixed to said frame portion. The first and second struts transfer the horizontal component of the reciprocating forces into the base plate. A plurality of tie rods span between a backing plate that mounts a hydraulic cylinder that drives the plunger, and the pump cylinder. A one piece pump housing and valve manifold is incorporated into the apparatus.
