Abstract

Abstract In the automatic evisceration of poultry the viscera is displaced from the body cavity of the bird through an access opening cut at the vent. In one form of the invention, a spoonlike removal tool applies pressure on the viscera away from the breast and drags the viscera along the backbone. In a second form, a removal tool in the nature of a loop captures the viscera and pulls it from the cavity. The entire operation takes place while the birds are advanced continuously by an overhead conveyor from which they are suspended by their legs. A series of birdreceiving carriages travel around a loop in timed relation to the conveyor, and each carriage is provided with an individual removal tool which enters the cavity on an arc that conforms to the configuration of the breast. At the completion of the operation, a latch is released to remove spring pressure from the tool, causing the latter to swing clear and permitting the eviscerated bird to continue along the conveyor line for successive processing operations.
