Squeeze chute with livestock restraints

An animal holding chute including:

• a. a rectangular chute having an entrance gate, an exit gate, an interior, a top, a first side and a second opposed side, the first and second sides include a tubular first and second top side rail;
• b. a first restraint mechanism mounted on the first top side rail and a second restraint mechanism mounted on the second top side rail opposite the first restraint mechanism, wherein each restraint mechanism is rotatable about the top rail that it is mounted on through a side opening in the chute proximal the chute exit between a substantially horizontal position outside of the chute to a more vertical position within the interior of the chute and wherein each restraint mechanism includes
• a tubular gripper support encircling a segment of the top side rail on which the restraint mechanism is mounted wherein the encircled segment of the top side rail is aligned with the side opening,
• a gripper,
• a gripper extender having a first end attached to the gripper support and a second end attached to the gripper, wherein the extension or retraction of the gripper extender adjusts the distance between the gripper support and the gripper, and
• a gripper rotator having a hydraulic cylinder mounted on a first end to the top rail with a cylinder rod attached to the gripper support, wherein the extension or retraction of the cylinder rod rotates the restraint mechanism about the top rail on which it is mounted;
• and
• c. a pusher mounted on a horizontal cross-rail that is transverse to the top rails of the first and second sides, wherein the pusher is rotatable about the horizontal cross-rail that it is mounted on, the pusher is rotatable between a preselected first position that is a substantially horizontal position away from the interior of the chute to a preselected second position that is a more vertical position closer to the interior of the chute and wherein the pusher is movable toward and away from the interior of the chute along a longitudinal axis of the chute such movement along the two side top rails mounting the side restraints.

An animal holding chute including:

• a. a rectangular chute having an entrance gate, an exit gate with a head opening that allows a head of an animal in the chute to pass through the head opening to an exterior of the chute, an interior, a top, a first side and a second opposed side, wherein the first and second sides include a tubular first and second top side rail;
• and
• b. a pusher rotatably mounted on a horizontal cross-rail that is transverse to the first and second top side rails, the pusher having
• a tubular pusher support encircling a segment of the cross-rail;
• a pusher body having a proximal end mounted on the pusher support and an opposed distal end;
• a pusher rotator having a hydraulic rotator cylinder mounted on a first end to the pusher support and a second end mounted to the cross-rail, wherein the extension or retraction of a rotator cylinder rod rotates the pusher about the cross-rail between a substantially horizontal position away from the interior of the chute to a substantially vertical position closer to the interior of the chute;
• and
• a pusher placement mechanism having a hydraulic placement cylinder mounted on the top of the chute wherein an extendable rod end of the cylinder is attached to the cross-rail and wherein each end of the cross-rail is transversely mounted to a tubular section having a bore that encircles one of the top side rails thereby rendering each tubular section slideable along an adjustment length of the top side rail that it encircles wherein the extension or retraction of the rod end of the placement cylinder moves the pusher toward and away from the interior of the chute along a longitudinal axis of the chute.

An animal holding chute including:

• a. a rectangular chute having an entrance, an exit, an entrance gate, an exit gate with a head opening that allows only a head of an animal in the chute to pass through the head opening to an exterior of the chute, an interior, a top, and a first side and a second opposed side, wherein the first and second sides include a tubular first and second top side rail running parallel to the longitudinal axis of the chute from the entrance to the exit, a plurality of side rails mounted on the sides parallel to the first and second side rails that extend from the entrance at least 50 percent of a length of the first and second top side rails towards the exit leaving an opening under the top rails proximal the exit;
• b. a first restraint mechanism mounted on the first top side rail and a second restraint mechanism mounted on the second top side rail opposite the first restraint mechanism, wherein each restraint mechanism is rotatable about the top rail that it is mounted on through the side opening from a substantially horizontal position outside of the chute to a more vertical position within the interior of the chute, wherein each restraint mechanism having
• a tubular gripper support encircling a segment of the top side rail on which the restraint mechanism is mounted wherein the encircled segment of the top side rail is aligned with the side opening,
• an arcuate gripper,
• a gripper extender having a first end attached to the gripper support and a second end pivotally attached to the gripper, wherein the extension or retraction of the gripper extender adjusts the distance between the gripper support and the gripper, and
• a gripper rotator having a hydraulic cylinder mounted on a first end to the top rail with a cylinder rod attached to the gripper support, wherein the extension or retraction of the cylinder rod rotates the restraint mechanism about the top rail on which it is mounted;
• and
• c. a pusher rotatably mounted on a horizontal cross-rail that is transverse to the first and second top side rails, the pusher having
• a tubular pusher support encircling a segment of the cross-rail;
• a pusher body having a proximal end mounted on the pusher support and an opposed distal end;
• a pusher rotator having a hydraulic rotator cylinder mounted on a first end to the pusher support and a second end mounted to the cross-rail, wherein the extension or retraction of a rotator cylinder rod rotates the restraint mechanism about the cross-rail between a substantially horizontal position away from the interior of the chute to a substantially vertical position closer to the interior of the chute;
• and
• a pusher placement mechanism having a hydraulic placement cylinder mounted on the top of the chute wherein an extendable rod end of the cylinder is attached to the cross-rail and wherein each end of the cross-rail is transversely mounted to a tubular section having a bore that encircles one of the top side rails thereby rendering each tubular section slideable along an adjustment length of the top side rail that it encircles wherein the extension or retraction of the rod end of the placement cylinder moves the pusher toward and away from the interior of the chute along a longitudinal axis of the chute
• whereby the pusher urges an animal entering the chute forward to place its head through the head opening to secure the animal within the chute, then the first and second side restraints are rotated and extended to exert bias against a ventral region of the animal.
