ABSTRACT:
An animal gate latch mechanism having upper and lower latch units movable successively and alternatively between gate open and gate latching positions therefor by a linkage system including a single actuating arm. From a gate open position of both latch units, movement of the actuating arm in one direction will independently move the latch units to the gate latching positions therefor. An intermediate latched condition of the gate is thus provided which can quickly and easily be effected by an operator on horseback. With both latch units in the latched position therefor, the gate is securely latched at two spaced-apart locations to prevent twisting of the gate by a confined animal and its possible escape therethrough.
