Abstract: The poultry shackle assembly (10) includes an upper hanger rod (11) and a lower carcass hanger (12). The legs (44 and 45) of a poultry carcass (46) are inserted into the leg recesses (42 and 43) of the carcass hanger. Guide rods (66, 67 and 68) tilt the carcass hanger (12) and the carcass (46) to an attitude suitable for visual inspection of the visceral cavity (49) of the carcass (46). Lock collar (48) moves downwardly along the hanger rod (11) until it is received in the lock recesses (58) of the clevis plates (34 and 35) of clevis (32), thereby holding the carcass (46) in the desired attitude for visual inspection. Later, the lock collar (48) is lifted by a guide rod (67) out of locking engagement with respect to the clevis (32), to permit the carcass (46) to reassume its vertical orientation for further advancement along the processing line.
