Abstract
Abstract A tension adjusting device, alongside a conveyor frame, which provides a meat animal passage, and alongside a shackle-equipped animal transportation track, is supported inwardly of the shackle chain for movement up and down or toward and away from the passage so as to yield when the shackle is applied to an animal''s leg and then to swing outwardly and/or down to maintain tension upon the attached shackle as the animal moves through the passage.
