BACKGROUND OF THE INVENTION
Squeeze chutes are well known and conventionally include a generally channel shaped frame structure having a head end for receiving a head of an animal to be confined, two sides each for extending along a respective side of the animal to .. be confined, a tail end remote from the head end. A head gate assembly at the head end is operable to move from a release position to a closed position in which the neck of the animal is grasped for confinement of the animal. In some cases, a squeeze side panel is arranged along one side and is operable in a pivoting action to squeeze the animal from one side onto the other side panel so that the body of the animal is also confined. A tail gate section is often provided at the rear end to close behind the animal as it enters the squeeze chute.
The head gate typically comprises a pair of parallel vertical bars with a spacing between them sufficient to receive the neck of the animal without damage but insufficient for the head to be pulled out of the bars and insufficient for the animal to move forward. Each of the bars forms part of a frame which pivots about a vertical axis parallel to the bar and spaced outwardly of the bar. In the locked holding position the frame and the bars line in a common plane transverse to the
2 chute with the bars at their point of closes approach. In a set portion the bar pivots so that it moves along the chute toward the incoming animal with the frame inclined out of the common plane thus increasing the space between the bars.
Thus to catch the cattle by the head, it is common to have a head gate that locks by itself as the cattle try to walk through it. When set in the set catch position, the bars are turned toward the approaching cattle. The approaching animal will see an opening sufficient for its head and try to walk through. The head will fit through the opening, but as the animal tries to walk forward its shoulders hit the bars and the bars move forward with the shoulders until the bars hit a latch at a top of the head gate locking them in the catch position in which the bars lie in the common plane. Normally head gates have a handle projecting out of the frame of one of the bars to one side of the chute which allows a worker standing to that side to push the handle to pivot the frame about its vertical axis that helps pivot head gate to be closed.
Head gates have been manufactured in this construction for many years and many manufacturers have arrangements which operate effectively in this manner. It will be appreciated that the animals concerned are very large and strong with great ability to do damage to themselves and the worker. It is thus highly desirable that even highly recalcitrant animals are trapped in the head gate as quickly and simply as possible with little possibility to back up before being trapped.

DETAILED DESCRIPTION
A squeeze chute generally indicated at 10 is formed by a frame structure 11 forming a front panel 12, a rear panel 13, a first side 14 and a second side 15. Each of the panels is formed by vertical posts so that the front panel includes posts 16 and 17 and the rear panel includes posts 18 and 19. The front and rear panels are connected by horizontal rails 20 and 21 at the top part of the frame
7 forming a rigid channel shaped frame structure into which an animal to be confined can enter from the rear panel to a position between the side panels and rearwardly of the front panel.
The front panel includes a head gate assembly generally indicated at .. 22 including a first door 23 and a second door 24 each of which is pivotally mounted for opening and closing movement around a vertical axis at or adjacent the post from a closed or confinement position shown in FIG. 1 to a receiving position in which the doors are pivoted to face inwardly and to the chute so that the animal pushes its head between the doors as it tries to escape out of the front of the squeeze chute with the animal automatically pushing the doors to the closed confinement position as it engages the doors. The doors can then be pivoted to a release position facing outwardly of the front of the squeeze chute in which the animal can escape when the confinement is no longer required.
As shown the doors are mounted for pivotal movement around axes at or adjacent the vertical posts 16 and 17 on bushings. However as will be well known to one skilled in the art, alternative support arrangements for the doors may be provided as required. Suitable latching devices for the doors in the closed position will also be provided but are not shown herein for convenience of illustration and will be well known to one skilled in the art. In addition in many cases a cable control assembly is provided which connects the doors and ensures that the doors remain in synchronism so that if one door is pushed, both of the doors move into the required

The doors can then be pivoted to a release position facing outwardly of the front of the squeeze chute in which the animal can escape when the confinement is no longer required.
As shown the doors are mounted for pivotal movement around axes at or adjacent the vertical posts 16 and 17 on bushings. However as will be well known to one skilled in the art, alternative support arrangements for the doors may be provided as required. Suitable latching devices for the doors in the closed position will also be provided but are not shown herein for convenience of illustration and will be well known to one skilled in the art. In addition in many cases a cable control assembly is provided which connects the doors and ensures that the doors remain in synchronism so that if one door is pushed, both of the doors move into the required
8 location. The doors can be manually operated by a lever 25 which projects outwardly from the post 17 toward the side 15 of the squeeze chute.
The pair of head gate doors 23 and 24 are arranged with each door having a vertical bar 26, 27 for cooperating with the vertical bar of the other of the doors to trap the neck of the animal therebetween. Each door is mounted on a hinge support member 28, 29 carried on the support frame for pivotal movement of the door and its vertical bar about a respective vertical pivot axis 30, 31 generally parallel to the first vertical post member and spaced outwardly toward a respective side of the support frame 11.
The doors are movable from the closed position shown in Figures 1 and 2 in which the vertical bars lie in a common plane P including the pivot axes 30, 31 to an open position in which the vertical bars are positioned on a side of the common plane P facing the rear end of the chute and the incoming animals to allow the head of the animal to enter between the bars while they are spaced apart.
In order to allow the worker to better control the closing of the gate in the event that one animal n the chute becomes nervous or disoriented and wants to back up from the gate, a transverse abutment member extends across the vertical bars in the open position adjacent a top of the vertical bars and is movable to assist in closing the gate. This comprises a simple bar 35 across the rear face of the gates which extends to either side of the top part of the posts 26 and 27. At this location the posts are closer together as indicated at portions 26A and 27A so that the posts are very close at this upper end portion. The posts are further apart at the height

Each door is mounted on a hinge support member 28, 29 carried on the support frame for pivotal movement of the door and its vertical bar about a respective vertical pivot axis 30, 31 generally parallel to the first vertical post member and spaced outwardly toward a respective side of the support frame 11.
The doors are movable from the closed position shown in Figures 1 and 2 in which the vertical bars lie in a common plane P including the pivot axes 30, 31 to an open position in which the vertical bars are positioned on a side of the common plane P facing the rear end of the chute and the incoming animals to allow the head of the animal to enter between the bars while they are spaced apart.
In order to allow the worker to better control the closing of the gate in the event that one animal n the chute becomes nervous or disoriented and wants to back up from the gate, a transverse abutment member extends across the vertical bars in the open position adjacent a top of the vertical bars and is movable to assist in closing the gate. This comprises a simple bar 35 across the rear face of the gates which extends to either side of the top part of the posts 26 and 27. At this location the posts are closer together as indicated at portions 26A and 27A so that the posts are very close at this upper end portion. The posts are further apart at the height
9 where the animal head enters. An operating device movable by a worker is provided for moving the bar 35 toward the common plane P to push the vertical bars into the closed position.
The transverse bar 35 is horizontal and generally parallel to the common plane P and is mounted on a pivot mounting rod 36 standing upwardly from the bar 35 at right angles to the bar for pivotal movement. The rod 36 is carried on a pivot bracket 38 which provides pivotal movement of the rod 36 about a horizontal axis of a pin 37 generally parallel to the common plane P. The bracket is carried on a cross member 12A of the front panel 12 of the frame 11A so that the pin 37 is above the vertical bars 26A, 27A.
The operating device includes an elongate manually pull cord 39 extending from a connector 40 at the top of the rod 36 at the head gate doors in a direction toward the rear end 13 of the chute that is toward the incoming animals to allow the worker to pull the doors to the closed positon from a remote location at a rear of an incoming animal.
That is the worker handling the animals can stand to one side of the chute at or adjacent the rear 13 of the chute and can encourage the animal from the rear to move forward. In the event that one animal looks to back up due to nervousness of the head gate, while the neck remains at the head gate, the worker can pull the cord and push the bars 26, 27 into the closed positon without assistance from the animal pushing forward.
