Abstract
Abstract A ventilating cap essentially consisting of an inner frame and a shell having the shape of an inverted cup and dimensioned to envelop the frame. The frame includes a hat band extending in a closed loop about an axis and ribs attached to the band in circumferentially spaced relationship. The ribs extend from the band in a common axial direction and converge toward the axis. Respective portions of the ribs remote from the band and adjacent to the axis are fastened to each other. The rim portion of the shell is releasably fastened to the outer face of the head band in spaced relationship so as to define an annular ventilating gap, and an opening in the shell aligned with the fastened portions of the ribs may be obstructed at least in part by a larger disc releasably fastened to the ribs.

Claim 1
Independent Claim
195 words
Headwear comprising: (a) a hat band extending in a closed loop about an axis and having an inner face and an outer face; (b) a plurality of rib members attached to said band in circumferentially spaced relationship, (1) said rib members extending from said band in a common axial direction and converging toward said axis, (2) respective portions of said rib members remote from said band and adjacent said axis being fastened to each other; (c) a shell dimensioned spacedly to envelop said band and said rib members, (1) said shell having the approximate shape of a cup and including an annular rim portion bounding an open side of said shell and a bottom wall formed with an opening therein; (d) fastening means on said rim portion for releasably fastening the same to the outer face of said hat band in a position in which said rim portion and said outer face define therebetween a ventilating gap and said opening is axially aligned with said portions of the rib members; (e) a disc member larger than said opening; and (f) securing means for releasably securing said disc member to said portions of the rib members.
