The latches being typical, we will describe but one in detail. it one side of pivot 25 is provided a hook 28 having bevel or cam nose Q9 and adapted to engage beneath behind an associated keeper bar At-the other side of pivot 25 is provided" a projection or tooth 80 which extends at substa-i'itially right angles withlthe body or the latch;
