Abstract: A versatile head gear system includes a hat having a vertical wall in which an opening has been made, and a seam formed about the periphery of the opening; one part of a two-part hook-and-pile type fastening means filling the opening and sewed to the seam; a number of cloth panels each of substantially the same size as the opening and bearing a name, logo, character, or other message on one side thereof; and each of the cloth panels having the other part of the two-part fastening means secured on its other side so that it may be attached to the hat when its particular name, logo, or other message has been selected for display with the hat.

Abstract: An emblem bearing cap attachment has a substantially planar, relatively stiff body defining a forward surface and a rearward surface. A primary crease extends centrally across the planar body defining an upper facing panel and a lower backing panel. The primary crease facilitates folding of the body about and capturing the band of a baseball style cap to position the rearward surface of the facing panel in confronting relationship with the inside surface of the crown rearward portion whereat are fastening means to secure the backing panel to the cap. The facing panel allows the display of emblems or other indicia thereon whether the facing panel is folded upwardly or downwardly.

Abstract: A detachable plaque for a cap having a visor and an adjoining crown portion is provided. The plaque generally comprises a flexible plastic sheet-like member having a live hinge or crease which defines a boundary between an upper portion of the sheet-like member and the lower portion of the sheet-like member, a first coupling or mating device incorporated on the upper portion of the sheet-like member for detachably engaging a mating member on the crown portion of the cap, and a second coupling or mating device incorporated on the lower portion of the sheet-like member for detachably engaging a second mating member on the visor of the cap. The first and second coupling means may be snaps and/or snap receivers, sockets and/or domed plugs, Velcro hook and/or loop fasteners, etc. In accord with one embodiment of the invention, the flexible plastic sheet has an aperture in at least the upper portion for receiving a piece of cardboard or paper on which a message or information is printed.

Abstract: A cap having a writing surface attached to its crown. The writing surface is configured to erasably receive writing inscribed thereon by the wearer. There is also included at least one writing implement for inscribing the desired expression or design on the writing surface. The writing implement is removably attached to one of the sides of the cap.

The eraser is also removably attached to one of the sides of the cap.

Abstract: The visual attractiveness of a variety of otherwise-autonomous articles may be significantly enhanced through the inclusion of an apertured, internally light-transmissive, peripherally light-intrareflective panel which is edge-illuminated and energized by elements self-contained within the article body. Article apertures of distributed area, point size or both may be thusly illuminated. Distributed-area display effects may be enhanced through aperture-aligned light-concentrative discontinuities formed in the panel. Enhancement of point-display effects may similarly be achieved through point-aperture-aligned, light-concentrative point discontinuities likewise formed in the panel. Point effects may also be enhanced through the employment of an end-illuminated, aperture-aligned, point-discontinuous optical fiber in conjunction with a subject apertured panel. Bi-directional display effects in subject autonomous articles may be achieved by means of a layered panel having oppositely-projective surfaces.

Abstract: A hat having an electric motor driven rotatable display placard affixed to the top exterior of the hat. The driving motor of the placard is powered by a photovoltaic panel attached to the exposed surface of the hat. An electrically conductive circuit connects the photovoltaic panel to the motor. The placard is imprinted with written or graphic advertisements or symbols, and is rotated to attract greater attention.

Abstract: A hat for souvenir collectors or sports fans is disclosed. The hat has two hand extensions attached to the front brow. An elastic strip is attached to the front brow in a manner that pulls the hands together. A string which is looped under the chin is provided to pull the hands apart, rapid pulling and releasing of the string produces a clapping action. Attached to each hand is a noisemaking device. A flexible sheet is attached to the hands on which appears a printed slogan. The slogan can be read when the hands are pulled apart.

Abstract: The present invention provides an improved hat with interchangeable patches that can be selectively attached to the hat. In the preferred embodiment, the hat is a standard, billed, baseball-style cap with some portion of a phrase or logo printed on its front surface, and a strip of fastening material or adhesive secured to the hat just below the incomplete phrase. A plurality of separate patches, each printed with a different completion to the hat's printed phrase or logo, and each with a back surface that is attachable to the fastening material on the hat, is provided. Thus the user can select the completion of the phrase with the patch of his choice. In this way a single hat can be used to carry a variety of different, and changing, phrases and logos.

Abstract: An aid for positioning a user's head with respect to a remote object is described. The device comprises a visor, having front and back edges, the visor being attached at its back edge to a headpiece. A pair of spaced line markings are provided on the underside of the visor, the markings being located substantially equidistant from an axis extending between the front and back edges and bisecting the visor. The distance between the markings closest to the back edge of the visor substantially corresponds to the distance between the eyes of the user.

Abstract: A baseball-type cap having on the front and above the visor a miniature transparent mug which contains a small motor and pump that circulates a fluid from the bottom of the mug up through a conduit within the cap to a small dispensing tap mounted above the mug. The tap handle operates an electrical switch to power the motor and also a lamp that back-lights advertising material visable through the transparent mug and illuminates the fluid flowing through a transparent tube connected between the dispensing tap outlet and the bottom of the mug. A top cover of the mug may support a plastic foam for further realism.

Abstract: An educational and recreational mathematical device comprises a ring or set of concentric rings or a band made endless or adapted to have ends thereof fastened to make them endless and a plurality of individual digits imprinted on the band or each ring at regularly spaced intervals. The digits when all read consecutively as a number constitute a quotient obtained by dividing a number constituted of (p-1)/n nines, in which P is a prime number greater than 5 and n is an integer at least 1, by P and adding to the left-hand end of said quotient any number of zeros necessary to increase the number of digits in the quotient to (p-1)/n or a specially chosen multiple of the quotient thus derived, n being so selected that (p-1)/n nines is the minimum number of nines divisible by P so that the quotient is an integral number.

Abstract: Headgear comprising a head-encircling band of extruded or molded thermoplastic having a channel formed along one edge and a transparent crescent-shaped plastic visor attached at its concave edge to the band within the channel so that said edge is concealed within the channel and said transparent visor, embodying within its diameter a pocket provided by a layer of plastic welded thereto within which is sealed a logo or emblem.
