with the adjacent edge portion 22 of the blade
I‘! whereby to releasably latch the blade I‘! in
collapsed position upon the body plate 50. This
keeper lug 2| may be formed as a solid member
upon the body plate It or it may be, as shown,
struck from such plate, and in either instance
the result will be the same.
In Figs. 4 and 5, I have illustrated modi?ed
