  • Patent number: 5938517
    Abstract: The holding fixture has a narrow neck fork designed to fit entirely inside of and between the shoulder joints of the carcass so as to utilize the inside surfaces of the shoulder joints as a means of centering the carcass and precluding side-to-side movement thereof. Each arm of the fork is narrow enough to fit entirely between the neck and the corresponding shoulder joint. A modified fixture for use with a crop-inclusive eviscerator has a resilient projection on the backrest between the arms of the fork to yieldably push the backbone at the base of the neck out away from the backrest to facilitate snagging of the esophagus by a hook-shaped dislodging tool utilized as part of the eviscerator.
