Abstract
A head gate for pen confining structures is disclosed. The head gate utilizes two synchronized gates with a gap there between. When the animal enters the gate, the gap is lodged in its open position. As the animal moves forward, the neck of the animal fits between the gap of the closing gates and rotates the gates forward and shuts. After the gates have closed, the animal cannot remove his head for the gates are held in position by a stop mechanism.
Claims4
An animal head gate comprising:
- two vertical sides;
- a gate whose width is less than half the distance between the two vertical sides;
- a second gate whose width is less than half the distance between the two vertical sides;
- a means for rotating the first and second gates in synchronization;
- a means for preventing the gates from rotating forward of the two vertical sides;
- a means for locking the gates in position when the gates abut the means of preventing the gates from rotating forward;
- a horizontal bar affixed between the two vertical sides near the upper limit of the two vertical sides;
- a horizontal platform extending from the horizontal bar rearward;
- a hinge affixed at the rear of the horizontal platform;
- and
- a plate secured to the hinge such that when pressured the plate can be lifted to abut the horizontal platform and when the pressure is released the plate drops to an angle less than 90.degree..
