ABSTRACT:
A directional and size limiting gate for controlling the flow of animals between adjacent pens. Vertically disposed frame members are spaced apart in the form of an equilateral triangle. Latch and hinge arrangements along each vertical door edge permits a door to open from, or pivot from, any one of the frame members. The door has tabs horizontally extending beyond the vertical edges of the door. Each side of the door has a control rod guided by apertures in the tabs, with the control arm having hinge pins thereon. The hinge pins secure the tabs of the door to hinge sockets at spaced locations along the vertically disposed frame members. Some horizontally disposed frame members have sockets for receiving bars, said sockets being variably positionable along the horizontal frame members for controlling the size of animal passing therebetween and/or for holding one edge of the door in a selected position.
