Abstract: A portable squeeze chute apparatus. The apparatus includes a chute having opposing sidewalls, an entrance end and an exit end. The sidewalls are selectively pivotable toward one another in order to inhibit lateral movement of an animal positioned in the chute. Movement of the sidewalls is actuated through a control chain which is connected to the sidewalls through a mechanical linkage. The control chain is selectively latched in position by a lock which is pivotally connected to the chute. The lock includes a tubular body through which the control chain passes. The tubular body includes a notch which selectively engages the control chain. A tailgate having interconnected door sections is mounted on the entrance end of the chute for selectively admitting an animal to the chute The tailgate and the sidewall squeezing mechanism include special mountings and bumpers which are adapted to reduce noise generated by operation of the apparatus.

Abstract: An improved portable squeeze chute apparatus and method includes a chute having an entrance end, an exit end, opposing sidewalls, a base, and a superstructure. Each of the sidewalls has an openable upper panel and lower panel for accessing upper portions and lower portions, respectively, of an animal positioned in the chute. Each of the sidewalls is selectively pivotable about a plurality of generally horizontal axes in order to immobilize lateral movement of an animal positioned in the chute. An exit gate having a neck clamp, positioned at the exit end of the chute, has interconnected neck clamp side portions for selectively clamping the animal's neck. An entrance gate has interconnected entrance gate side portions for selectively preventing the animal from exiting rearwardly from the chute. Various portions of the apparatus are each controllable by a respective hydraulic piston and two-way valve arrangement.

Abstract: An animal working device includes a front enclosure with front and back ends, opposite sides, a base and a superstructure. The front enclosure includes opposite side walls each at a respective side and a gate in one of the sides. A back enclosure includes front and back ends, opposite sides, a base and superstructure. The back enclosure is telescopically received in the front enclosure and is movable between extended and retracted positions with respect thereto. In its extended position, the back enclosure communicates with the front enclosure. An elevation system is provided for raising and lowering the device between a work position on a ground surface and a transport position elevated thereover. A wheeled, retractable undercarriage is mounted on the back end of the front enclosure for raising, lowering and transporting the device.
