Writing instrument for alternately writing in fluorescent transparent and nontransparent ink
First Claim
1. A writing instrument, 10, for forming continuous lines capable of writing alternately in fluorescent transparent and nontransparent ink comprising:
- i) a first elongated body, 12, having a first nib, 16, and a second nib, 14, at one end of the elongated body;
ii) the first nib, 16, being retractably mounted in the end and being axially aligned with the longitudinal axis of the elongated body, 12;
iii) the second nib, 14, being fixed in the same end and spaced from the longitudinal axis of the elongated body, 12 and extending a length which is different from the extended position of the retractable nib, 16;
iv) the first retractable nib, 16, consisting of a substantially rigid nib in fluid communication with a reservoir on nontransparent ink, 20, which reservoir is held in a barrel, 22, attached to the retractable nib which barrel extends and retracts with the retractable nib;
v) the second nonretractable nib, 14, consisting of a porous nib in fluid communication with a reservoir of fluoresecent transparent ink, 18;
vi) a slidable locking mechanism, 24, for extending and retracting the nib, 16, with a simple finger motion without requiring the user to alter the writing angle or causing the user to rotate the instrument in the hand comprising;
i) a slidable sleeve, 36, containing the barrel, 22, of the retractable nib, 16, which sleeve is attached to a flattened archy, 38;
ii) an arch, 38, rising from the sleeve, 36, which is flattened at it apogee and contains, at its apogee a hole capable of accepting the perpendicular shaft of the locking button, 32, when the shaft is depressed;
iii) a perpendicular shaft, 32, that has, at one end an oval locking button which protrudes from the outer perimeter of the elongated body, 12, of the instrument and at the opposite end is seated slightly above the hole at the apogee of the flattened arch, 38, which end is capable of being depressed through the hole when pressure is exerted on the oval locking button, located on said oval locking button adjacent said perpendicular shaft are locking protrusions;
iv) a spring, 40, surrounding the perpendicular shaft, 32, which spring is seated, at one end, on the flattened portion of the arch, 38, and on the opposite end, on the locking protrusions of the oval locking button, 32, which spring is capable of exerting upward pressure on the oval locking button and the perpendicular shaft, 32, but will compress when the oval locking button is depressed.

Abstract
A writing instrument comprises nonretractable nib 14 made of porous material and being in fluid communication with an ink reservoir of fluorescent transparent ink, the nib colloquially known as a "highlighter". A second nib 16 is retractable and is substantially rigid and is in fluid communication with a second ink reservoir of nontransparent ink, the second nib colloquially known as a "ball point pen". The retractable and nonretractable nibs extend from an angular face of an elongated body in which they are contained. The angular face permits the nonretractable and retractable nibs, which are in parallel relation, to extend in spaced relations so that the retractable nibs extends beyond the nonretractable nib whereby the nonretractable nib does not contact the writing surface when the retractable nib is used as writing instrument. The extension and retraction of the retractable nib is accomplished with a slidable locking mechanism which allows a user to extend a retractable nib with a single finger motion without altering the writing angle or rotating the instrument in his hand, as in the prior art.
