They are an old version of what we now call "Lawyer Lips".
Sheldon has a page on these.
The idea is, some bikes have a small slot in the dropout to accept these tabs, the axle goes through the hole and the little bent bit hooks into the hole in the dropout. If, by some unfortunate accident, the nuts or quick release come loose, the wheel won't fall straight out, rather sit in the drops for a little longer, wobbling like mad.
Modern forks tend to have lips on the bottom of the dropout, meaning you have to loosen the qr skewer or nuts more to remove the wheel.
Lawyer Lips.
