Abstract: This invention relates to a meat product press apparatus adapted to hold and compress ham members or the like during a meat packing plant processing procedures. The meat product press apparatus includes a lower press assembly interconnected by a main clamp assembly to a top press assembly. The lower and top press assemblies provide grate or grid type structures presented in spaced, parallel planes to clamp the meat product therebetween. The main clamp assembly includes an initial bias lock assembly to interconnect adjacent ends of the lower and top press assemblies and a pressure bias lock assembly to interconnect the spaced, opposite adjacent ends of the lower and top press assemblies. The initial bias lock assembly includes a pair of spaced spring members which are connectable to a cam lock member.
