6-6, respectively, of Fig. 2; and
Fig. 51s a sectional view illustrating the posi
tion which the ?anges may take when the cap is
applied to the head.
In the drawing I have shown a rubber cap of
the type known as full-fashioned or full-head
shaped (of the molded variety), but it is to be
understood that my invention may be applied
to caps of other types. The body of the cap is
shown at 8, and the same is provided with a por
tion ‘i which comes down on the forehead, and
portions 8 which cover the ears, and a portion
9 which extends across the back of the neck.
In the form illustrated, two water-excluding
?anges i8 and H are provided which are con
nected to the cap body (preferably integrally)
along lines spaced slightly upwardly from the
lower edge of the cap, and in general these
?anges have a curvature conforming generally
to that of the cap edge. The ?anges do not ex
tend across the forehead portion, as they are not
necessary in that region, and they therefore
terminate at the temple portions, as shown.
Each ?ange preferably extends continuously
from the temple portion at one side of the cap
tion of the other ?ange.
In the use of the cap, which is applied to the
head in the customary manner, the yielding thin
corrugated ?anges, when the cap is in place, are
?exed or displaced by contact with the head and
neck of the wearer so that they no longer main 35
tain their normal 'or perpendicular relation to
the cap body, but have their parts'moved lateral-’
1y so as to contact with their ?at surfaces against
the adjacent surfaces of the head and neck. In
other words, these ?anges, owing to their shape 40
and the material of which they are composed,
readily conform to the parts to which the mar
ginal part of the cap is applied. Fig. 5 shows‘ an '
example of positions which the ?anges may as
Vsume at one point in the cap margin, but it is
to be understood that in some places the ?anges
may conform more closely to the head or neck
than in the case illustrated in Fig. 5, and in
other places less closely. This feature is of some
importance in that a ?ange of the character de 60
scribed, by the diversity of the possible posi
tions of its parts at different points, when the
cap is applied to the head, is enabled to conform
to the head and neck parts more readily so as to
repel incoming water more uniformly than here- u
tofore at the di?erent points in the length of _ said wall being soft and yieldable, and following
the cap edge. In other words, the ?ange serves a zig~zag line made up of a multiplicity of short
effectively to repel water in the places where
there is usually a slight gap or space under the
cap edge, as well as in those places where the
cap edge has a tighter fit.
It will also be understood that the latitude in
the direction of bending or ?exing of the ?ange
portions is a feature of importance. In the case
10 illustrated in Fig. 5, parts of both ?anges are
?exed in an upward direction, but they will act
with equal e?iciency if ?exed'in a downward di
rection, for example, and they will act e?ective
ly regardless of the direction in which they are
15 ?exed and without the necessity of exercising
special care in adjusting the marginal portion of
the cap on the head.
While I have shown a cap in which two ?anges
are employed, it will be understood that in some
portions approaching toward and receding from
the margin in a course generally parallel and
close to the margin.
