Abstract: A paper hat is formed from stiffly flexible paper-like material such as kraft with a rectangular top panel forming a crown, and four planar side panels and four planar side panels attached to the top panel along fold lines. The side panels have lower arcuate borders forming an oval, head-shaped opening toward the crown. Four arcuate panels flare from the side panels forming a brim with an ovate outer edge. One of the side panels has a transverse fold line parallel and intermediate the crown and the brim allowing the side panel to be folded flat. Additional fold lines along hinges joining the side panels and fold lines perpendicular to the crown allow the hat to be folded into a flat form with all panels in parallel planes.

Abstract: A frame for simultaneously tensioning a web in two orthagonal directions including two spaced-apart primary members and two spaced-apart secondary members. Each of the members is disposed at right angles to an adjacent member to form a rectangle. They are linked together in a manner such that upon drawing the two primary members apart, they will simultaneously space the secondary members apart and stretch the web that is disposed therebetween.
