Abstract
Abstract A flashlight and writing implement combination wherein the device is interiorly illuminated, and ultimately conducts such illumination in either of two directions, depending upon on which end the cap of the implement is placed. The cap includes reflective means for reversing light-flow back through the light-conductive or translucent barrel, toward the end piece and to the writing tip itself, concentrically thereabout. Optionally, the cap is disposed on the reverse end, in which event the light is actuated to send illumination in the opposite direction, the device thereby serving as a flashlight. Aperture means may be provided the cap so that the usually provided clip can be depressed to actuate the pressure switch of the implement. The cap can be made of a resilient deformable plastic material so that by squeezing the same the pressure switch means of the implement may be actuated.

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
162 words
A self-illuminating writing device including, in combination, a writing implement having a reverse end and a forwardly oriented writing tip, said reverse end being provided with light means, and a cap selectively positioned over said writing tip and also removable therefrom for selective positionment over said reverse end having said light means, said light means facing away from said tip for emitting observable light energy in a direction reverse to the forward orientation of said tip when said cap is removed from said reverse end, said implement including translucent structure transmitting said light energy proximate said tip, said cap including an internal reflector means, facing said light means when said cap is disposed on said reverse end of said writing implement, for reflecting light energy through said implement to said tip when said cap is so disposed on said reverse end of said implement, said implement including an internal battery and switching means for selectively coupling said battery to said light means.
Claim 2
Dependent Claim
162 words
A self-illuminating writing device including, in combination, a writing implement having a reverse end and a forwardly oriented writing tip, said reverse end being provided with light means, and a cap selectively positioned over said writing tip and also removable therefrom for selective positionment over said reverse end having said light means, said light means facing away from said tip for emitting observable light energy in a direction reverse to the forward orientation of said tip when said cap is removed from said reverse end, said implement including translucent structure transmitting said light energy proximate said tip, said cap including an internal reflector means, facing said light means when said cap is disposed on said reverse end of said writing implement, for reflecting light energy through said implement to said tip when said cap is so disposed on said reverse end of said implement, said implement including an internal battery and switching means for selectively coupling said battery to said light means.
Claim 3
Dependent Claim
22 words
The combination of claim 1 wherein said writing implement includes a translucent barrel having a translucent end piece receiving said writing tip.
Claim 4
Dependent Claim
27 words
The combination of claim 1 wherein said writing tip comprises a hollow, ink filled, translucent, replaceable writing cartridge having a writing element communicating with the interior thereof.
Claim 5
Dependent Claim
54 words
The structure of claim 1 wherein said switching means comprises a pressure-actuated switching means carried on a side of said writing implement proximate said point, said cap being formed of yieldable material, whereby thumb-and-finger pressure against said cap to distort the transverse cross-section thereof so to engage said switch means to produce actuation thereof.
Claim 6
Dependent Claim
53 words
The structure of claim 1 wherein said switching means comprises a pressure-actuated switching means carried on a side of said writing implement proximate said point, said cap having a barrel provided with a wall aperture and also a resilient clasp depressable through said aperture to thrust against and thereby actuate said switching means.
Claim 7
Dependent Claim
27 words
The structure of claim 1 wherein said cap and writing implement have mutually intercooperable means for effecting both continuous and also intermittent actuation of said switching means.
Claim 8
Dependent Claim
20 words
The structure of claim 2 wherein said end piece is integrally formed with said barrel and carries said switching means.
