Abstract: A livestock squeeze chute includes upright sides mounted on the frame by parallelogram supports that permit movement of the sides toward and away from one another while always maintaining the sides parallel. The sides are coupled together for opposite equidistant movement by arms that extend from the respective sides and connect to a common shaft at the forward end of the chute. A hand lever is provided to rotate the shaft and effect movement of the sides toward and away from one another. A ratchet lock mechanism acts automatically to retain the sides against outward movement. A release is selectively operable to release the ratchet lock mechanism. The sides include panels and bar sections which are removable to provide access to the entire body of an animal in the chute.
