Abstract
In the evisceration of poultry a special, slender tool is guided into the body cavity of the bird through an opening at the vent. A small diameter connection between the crop and the stomach is hooked by a finger on one end of the tool which swings into gathering relation to such connection after insertion is complete. The hook-like finger brings the viscera connection against a post, rigid to the tool adjacent the finger, all without any squeezing, pinching or clamping or other damaging action. The connection is draped over the bight of the finger and between a pair of anti-slippoff abutments such that the fold-over, wrap-around wrapping action effectively captures the connection before the pull-out motion commences. The swinging return of the finger to its normal position, for release of the viscera package, takes place only after the tool, including its guide, its post and its finger are outside the body cavity.
