Abstract
An adjustable width livestock working alley for handling various size animals including a stationary support frame supporting a first arcuate-shaped stationary outer wall and a second arcuate-shaped moveable inner wall including multiple sections, pivotally joined together at the ends of the sections so that the effective radius of the overall inner wall can be changed. A series of connecting links, connecting the support frame to the multiple arcuate sections at their pivot joints with each connecting link starting with the first link having the shortest length with the links of each additional section being proportional to the accumulated changes in the circumferential length of the wall sections as the effective radius of the inner wall is changed and power means connected to the multiple sections for moving those sections radially and longitudinally to change the effective radius of the inner wall.
