A speci?c embodiment of the invention has been chosen
for purposes of illustration and description, and is shown
in the accompanying drawings, forming a part of the
speci?cation, wherein:
FIG. 1 is a vertical cross~sectional view of a ?reman’s

headgear of the general types disclosed and described in
FIG. 3 is an enlarged fragmentary perspective and
