Patent ID: 7832363

Claim:
An adjustable livestock alleyway, comprising; a) an alleyway frame having first and second side walls defining an entrance for receiving livestock and an exit for discharging livestock, b) a center frame located between the first and second side walls of the alleyway frame defining first and second side by side alleyways, c) first and second panels pivotably mounted at their lower ends to the alleyway frame at locations spaced away from the center frame, the first and second panels each pivoting about a longitudinal, horizontal axis of rotation which is spaced away from the center frame and toward the lower end of the alleyway frame such that the first and second panels rotate between a first open position in which the first and second panels are pivoted toward the center frame thereby causing the first and second side by side alleyways to increase in width for accommodating larger animals and a second constricted position in which the first and second panels are pivoted away from the center frame thereby causing the first and second side by side alleyways to decrease in width for accommodating smaller animals, and, d) a pivot mechanism operable for pivoting the first and second panels between the first open position and the second constricted position, whereby an operator may selective pivot the first and second panels in a pre-selected position between the first open position and the second constricted position.
