Abstract
Abstract A latch apparatus for use with gates includes a latch bracket and a latch bar which removably engages and is locked to the latch bracket. The latch bracket includes a plurality of inclined slots which accept pins mounted on the latch bar and a catch member which is spring loaded to bear downward on the top portion of the latch bar when the latch bar is engaged in the latch bracket. To release the latch bar from the latch bracket, the catch member is swung away from the latch bar and the latch bar lifted so that the pins slide out of the slots in the latch bracket.
