ABSTRACT:
There is disclosed a leg transfer machine for unloading backs of chickens from a shackle conveyor and feeding the back of the chicken carcass into a conventional chicken leg processor. The machine is positioned under a shackle conveyor and includes an air cylinder-actuated rod positioned to strike both legs of the bird carcass just below the hocks and lift the hocks out of the shackle loop. A slotted guide receives the legs in respective slots with the hocks above the slots preventing the half of the chicken from dropping in an uncontrolled manner. A rake actuatable both vertically and horizontally is controlled to drop in front of the hocks and rake the legs back in the slots while generally vertical rail members contact the crotch of the chicken to cause the legs to extend horizontally as they descend onto an upwardly convex saddle element covering the end portion of the leg processing machine chain conveyor. A preferred embodiment has a second rake vertically oriented to forcibly slide the hocks down in the vertical extensions of the leg receiving slots. An air cylinder-operated pusher pushes the back of the chicken into engagement with the chain conveyor aided by a presser bar positioned to press down on the back as it moves under the impetus of the pusher bar. Stirrups on the side of the saddle element aid in centering the back half of the chicken on the saddle. The electrical control system includes detectors for presence of a shackle at the machine position and for the presence of a bird carcass on the shackle, and includes selector means for unloading every bird, second bird or third bird and thus several leg transfer machines may feed respective chicken leg processors from a single shackle conveyor.
