Eternal light

Abstract

The Eternal Light consist of a Battery housing cylinder assembly to constructed from clear acrylic plastic. This houses a Battery guide assembly to be constructed from white acrylic plastic. The battery separator is vertically attached to the battery housing. The bottom end is capped with a steel bottom spring assembly (negative contact) with eight adjustable prongs A red permanent ink dot on steel bottom spring assembly is used to indicate correct orientation of left and right spring assemblies which constitute the negative contact points. The top housing cover switch assembly to be constructed from red acrylic plastic with center punched hole and side cut rectangle slot opening for a 2-pole mini-switch assembly Inserted into Housing cover assembly and anchored with epoxy glue from underside 0.4 AA batteries are inserted with positive (+) facing switch assembly to complete the assembly.

Claims

1. We claim that the external light battery assembly will allow for extended battery operation of any d sized flash light or other battery operated devices which accepts in-line d sized flash light batteries: The D sized batteries can now be replaced by 4 AA batteries in two separate chambers allowing power to be drawn from ether chamber A or chamber as selected by the user. Reserve power may be selected by switch over from the primary channel (A) to the reserve channel (B) therefore doubling the service life of the battery operated device.
