Loin puller

An improved loin puller for pulling a selected carcass half and separating the loin and ribs thereof from the fat thereof, said improved loin puller comprising:

• a frame for elevating a working surface a selected distance above a support surface;
• a primary support/conveyor carried by said frame for conveying at least a back portion of said carcass half toward a selected location;
• a secondary support carried by said frame quarter including said ribs of said carcass half;
• a first cutting blade carried by said frame proximate said selected location, said first cutting blade being disposed a selected distance above said conveyor to define a depth of cut, said first cutting blade defining a selected cutting contour for separating said loin from said fat;
• a second cutting blade carried by said frame proximate a second selected location, said second cutting blade being disposed a selected distance above said conveyor to define a depth of cut, said second cutting blade defining a selected cutting contour for separating said ribs from said fat;
• a first cutting width adjustor carried by said frame for selectively narrowing and widening said cutting contour of said first cutting blade;
• a second cutting width adjustor carried by said frame for selectively narrowing and widening said cutting contour of said second cutting blade;
• a loin gripper carried by said frame for gripping said loin and forcing said loin and said fat in a direction toward said conveyor, said loin gripper including a plurality of chain members, at least two sprocket members carried by said frame, and a plurality of biasing members for biasing each of said plurality of chain members in a direction toward said primary support/conveyor, each of said plurality of chain members being comprised of a plurality of link members defining an endless loop configuration, said link members defining extended portions for engaging said loin, said sprocket members being positioned to maintain each of said plurality of chain members in said endless loop, said sprocket members being rotated by a motor, thereby engaging each of said plurality of chain members in travel along said endless loop, said plurality of biasing members being carried by said frame and including at least one idler wheel disposed within said loop defined by each of said plurality of chain members, said idler wheel being biased in a direction toward said primary support/conveyor;
• a rib gripper carried by said frame for gripping said ribs and forcing said ribs and said fat in a direction toward said conveyor, said rib gripper including at least one chain member, at least two sprocket members carried by said frame, and a plurality of biasing members for biasing said chain member in a direction toward said secondary support, said chain member being comprised of a plurality of link members defining an endless loop configuration, said link members defining extended portions for engaging said ribs, said sprocket members being positioned to maintain said chain member in said endless loop, said sprocket members being rotated by said motor, thereby engaging said chain member in travel along said endless loop, said plurality of biasing members being carried by said frame and including at least one idler wheel disposed within said loop defined by said chain member, said idler wheel being biased in a direction toward said secondary support;
• a first cutting blade heater carried by said first cutting blade for heating said first cutting blade during operation of said improved loin puller;
• and
• a second cutting blade heater carried by said second cutting blade for heating said second cutting blade during operation of said improved loin puller.
