Abstract:
A trouble light is provided with a metal protective cage which surrounds a light bulb and has planar surfaces. When energized by a separate switch, an electromagnet within the handle generates a magnetic field which magnetizes the protective cage, enabling it to be mounted to any convenient ferrous metal surface, such as the hood of a car.

Description:
BACKGROUND OF THE INVENTION 
     1. Field of the Invention 
     The present invention relates to a magnetic light and more particularly pertains to magnetically mounting a drop light to a metallic surface on the hood of an automobile with an on/off option with a magnetic light. 
     2. Description of the Prior Art 
     The use of drop lights is known in the prior art. More specifically, drop lights heretofore devised and utilized for the purpose of lighting to see the engine of an automobile are known to consist basically of familiar, expected and obvious structural configurations, notwithstanding the myriad of designs encompassed by the crowded prior art which have been developed for the fulfillment of countless objectives and requirements. 
     By way of example, U.S. Pat. No. 5,213,412 to Ciallella discloses a drop light with magnet and hook. 
     U.S. Pat. No. Des. 322,328 to Burgett discloses the design of a multi-position drop light. 
     U.S. Pat. No. 4,727,462 to Komonko discloses a clamp-on magnet for trouble lights. 
     U.S. Pat. No. 4,470,106 to Norton discloses a shop light. 
     U.S. Pat. No. 3,809,883 to Goodwin discloses a universal trouble light support. 
     While these devices fulfill their respective, particular objective and requirements, the aforementioned patents do not describe a magnetic light that magnetically mounts a drop light to a metallic surface on the hood of an automobile with an on/off option. 
     In this respect, the magnetic light according to the present invention substantially departs from the conventional concepts and designs of the prior art, and in doing so provides an apparatus primarily developed for the purpose of magnetically mounting a drop light to a metallic surface on the hood of an automobile with an on/off option. 
     Therefore, it can be appreciated that there exists a continuing need for a new and improved magnetic light which can be used for magnetically mounting a drop light to a metallic surface on the hood of an automobile with an on/off option. In this regard, the present invention substantially fulfills this need. 
     SUMMARY OF THE INVENTION 
     In the view of the foregoing disadvantages inherent in the known types of drop lights now present in the prior art, the present invention provides an improved magnetic light. As such, the general purpose of the present invention, which will be described subsequently in greater detail, is to provide a new and improved magnetic light and method which has all the advantages of the prior art and none of the disadvantages. 
     To attain this, the present invention essentially comprises an oblong hollow handle having an first end, a second end, an intermediate extent therebetween, an inner surface, an outer surface, an upper portion, and a lower portion.

     DESCRIPTION OF THE PREFERRED EMBODIMENT 
     With reference now to the drawings, and in particular, to FIG. 1 thereof, the preferred embodiment of the new and improved magnetic light embodying the principles and concepts of the present invention and generally designated by the reference number 10 will be described. 
     Specifically, it will be noted in the various Figures that the device relates to a new and improved magnetic light that magnetically mounts a drop light to a metallic surface on the hood of an automobile with an on/off option. In its broadest context, the device contains an oblong hollow handle, an electrical socket, a metal casing, and an electromagnet with the electrical socket and the electromagnet having an on/off option. 
     The device 10 contains an oblong hollow handle 12 having an first end 14, a second end 16, an intermediate extent 18 therebetween, an inner surface 20, an outer surface 22, an upper portion 24, and a lower portion 26. The upper portion 24 and lower portion 26 are coupled by a fastening means 28. The oblong hollow handle 12 is encompassed by an insulated plastic. A first switch 30 is integral with the outer surface 22. A second switch 32 is integral with the outer surface 22. 
     An electrical socket 34 is secured to the second end 16 of the oblong hollow handle 12. The electrical socket 34 functions to receive a light bulb. The electrical socket 34 has a wire 36 having a first end 38 and a second end 40. The first end 38 of the wire 36 is electrically secured to one end of the electrical socket 34. The second end 40 of the wire 36 has an electrical plug 42 thereattached. A push button switch 44 is attached to the electrical socket 34 thus allowing the light bulb to be in an on or off position. The push button switch 44 corresponds with the first switch 30 of the oblong hollow handle 12. 
     The device 10 contains a metal casing 46 that includes a plurality of planar surfaces. The metal casing 46 is secured to the second end 16 of the oblong hollow handle 12. The metal casing 46 has a generally flat surface. A metal cage 48 is hingedly secured to the metal casing 46. The metal cage 48 functions to prevent contact with a light bulb. 
     An electromagnet 50 is secured to the inner surface 20 of the intermediate extent 18 of the oblong hollow handle 12. The electromagnet 50 has a first wire 52 and a second wire 54. The first wire 52 is electrically connected with the metal casing 46. The second wire 52 is electrically connected with the second switch 32 of the oblong hollow handle 12 thus allowing the electromagnet 50 to be turned on to generate a magnetic field on the metal casing 46 or off to disengage the magnetic field. 
     The present invention is designed to be mounted on any adjacent and convenient metallic surface as one works. It is similar in construction to the commonly used &#34;drop light,&#34; except a solid metal casing, or cage, surrounds the area at the rear of the bulb; the front of the bulb is covered by the conventional meshed cage to prevent contact with the hot bulb and provide for the necessary illumination. 
     A steel rod, wrapped with a copper coil, is housed within the handle of the present invention, and this, connected with the aforementioned metal casing, serves to generate the magnetic field. The present invention also features two opposed switches on the handle, one to energize the field as needed, and the other for the light itself. Hence, it can be seen that, with both the light and the magnet turned on, one can place the present invention in any of an infinite number of positions to best illuminate the project at hand. 
     The alternatives are not attractive. A drop light typically incorporates a hook at its end from which it must be hung if one cannot hold the light. This practice usually results in compromising the area to be illuminated since one cannot always find the ideally located projection from which to hang the light. The present invention addresses and eliminates these problems; it may be placed indiscriminately at any location and will firmly maintain this position until the magnet is turned off. The present invention will be a valuable acquisition indeed for anyone having the need to perform automotive repairs as well as the &#34;do-it-yourselfer.&#34; 
     As to the manner of usage and operation of the present invention, the same should be apparent from the above description. Accordingly, no further discussion relating to the manner of usage and operation will be provided. 
     With respect to the above description then, it is to be realized that the optimum dimensional relationships for the parts of the invention, to include variations in size, materials, shape, form, function and the manner of operation, assembly and use, are deemed readily apparent and obvious to one skilled in the art, and all equivalent relationships to those illustrated in the drawings and described in the specification are intended to be encompassed by the present invention. 
     Therefore, the foregoing is considered as illustrative only of the principles of the invention. Further, since numerous modification and changes will readily occur to those skilled in the art, it is not desired to limit the invention to the exact construction and operation shown and described, and accordingly, all suitable modification and equivalents may be resorted to, falling within the scope of the invention.
