ABSTRACT:
A livestock sorting gate having a chute forming a path for guiding animals toward a pair of pens disposed in opposite relation to one another laterally of the path formed by the chute for receiving animals being guided down the chute. Access to at least one of the pens is selectively blocked by a gate in the form of a parallel crank four-bar linkage disposed in the chute adjacent the pens. A motor, connected between an adjoining pair of three fence-portions pivotally joined together and anchored to fixed pivots for forming the cranks and connecting rod of the linkage, acts to vary the angle included between adjoining sections of the gate in order to swing the gate transversely of the path formed along the chute so as to achieve the desired blocking and unblocking of access to the pens.
