Title: Mounting of battery-operated bulb

Description:
The present invention relates generally to improvements in the construction and operating mode in dwellings of battery-operated light bulbs, the improvements more particularly contributing to supplementing ambient lights in sites of use where necessary, all as will be better understood as the description proceeds. 
   BACKGROUND OF THE INVENTION 
   It is known from common experience, taking a closet as an example, that the ambient light which illuminates through an open door into the closet, is insufficient to identify hanging clothes or objects on shelves in the closet. As additional examples of ambient light shortcomings are garages and attics. 
   SUMMARY OF THE INVENTION 
   Broadly, it is the object to overcome the foregoing shortcoming of ambient light inadequacy. 
   More particularly, it is an object to provide a battery-operated light bulb that installs easily, in any site of use where extra light is needed for the utilitarian purposes of the user. 
   The description of the invention which follows, together with the accompanying drawings should not be construed as limiting the invention to the example shown and described, because those skilled in the art to which this invention appertains will be able to devise other forms thereof within the ambit of the appended claims.

   DETAILED DESCRIPTION OF THE INVENTION 
   In a typical end use, a battery-operated bulb generally designated  10 , serves as a light source in a closet, being mounted on an end wall  12 , and the battery from time to time must be replaced. To address this chore, the bulb construction includes a first outer cylindrical base  14  having a wall  16  bounding a mounting compartment  18 , within which compartment there are three circumferentially spaced-apart recesses, individually and collectively designated  20 . 
   Each recess  20  is configurated in an L-shape with a vertical leg  22  and a horizontal leg  24  subtending a ninety-degree angle  26  therebetween. 
   Cooperating with the outer cylindrical base  14  is a second inner cylindrical base  28  sized to fit within the mounting compartment  18  and on a wall  30  thereof having a similar matching array of three spaced-apart projections, individually and collectively designated  32 , thus providing an interconnecting projection  32  for each recess  20 . 
   Each projection  32  is provided with an operative position in projected relation within a cooperating one said recess vertical leg  22 , thus causing a projection  32  to seat in the angle  26 . Next, the user urges the outer base  14  in a rotational traverse, as noted by arrow  34 , within the inner base  28  which locks together the bases  14  and  28 . 
   A reverse rotational traverse  36  unlocks the bases  14  and  28 , enabling the user to withdraw the inner base  28  from the outer base  14  and concomitantly providing access to a battery-compartment  38  in the inner base  28  and replacement of the batteries. 
   While the apparatus for practicing the within inventive method, as well as said method herein shown and disclosed in detail is fully capable of attaining the objects and providing the advantages hereinbefore stated, it is to be understood that it is merely illustrative of the presently preferred embodiment of the invention and that no limitations are intended to the detail of construction or design herein shown other than as defined in the appended claims.
