Abstract
A portable lamp assembly which comprises a fuel containing container and a globe therefore, the globe having a plurality of convex reflective surfaces on an inner surface thereof to maximize light output. The globe also functions as a protective member for the fuel containing container when in a stored position for transportation.
Description
PORTABLE LAMP ASSEMBLY
FIELD OF THE INVENTION
The present invention relates to a lamp and more particularly, relates to a portable lamp utilizing a liquid fuel.
BACKGROUND OF THE INVENTION
Liquid fuel burners are known in the art and have been used for a number of years.
They are generally considered to be a disposable item and have been used both for providing lighting and for warming foods in chafing dishes and the like.
Typically, the burner includes a sealed container in which the fuel is stored and a wick that passes upwardly through the lid of the container. The fuel passes up through the wick and the wick is lit. When the fuel is exhausted, the container is typically discarded and replaced with a new unit.
Most disposable liquid fuel burners are relatively simple in structure and preset in the factory to provide for an optimum flame height by exposing a limited lamp wick above the top of the burner. The wick assembly, intended only for use with the single can, is relatively simple. One disadvantage of many of the disposable liquid fuel burners is the inherent danger in transporting the same. In many instances, it is desirable to transport the liquid fuel burner as, for example, when using the same on camping trips or the like. However, known liquid fuel burners generally are not designed for such use and particularly so when a relatively volatile fuel is utilized.
SUMMARY OF THE INVENTION
It is an object of the present invention to provide a disposable liquid fuel burner suitable for lighting purposes and which is compact in nature.
It is a further object of the present invention to provide a disposable liquid fuel burner for lighting purposes which is readily transportable.
In one embodiment of the present invention, there is provided a fuel burning assembly comprising a container designed to contain a fuel and a globe therefore, the container having a container side wall and a container top wall, the container top wall having an opening therein, an externally threaded neck surrounding the opening, the globe comprising a continuous globe side wall sized to fit externally of the container side wall, the globe side wall having an interior face and an exterior face and at least one member extending inwardly from the interior face and being arranged such that the member will rest on an upper portion of the container when the globe is placed over the container whereby the globe may fu.nction as a chimney.
The container having the liquid fuel therein, according to the present invention, is formed of a metallic material and is preferably cylindrical in configuration.
Located centrally in the upper side wall is an aperture which is designed to receive a wick device.
Surrounding the aperture is a neck, the neck preferably having external screw threads formed thereon to receive a cap. The top of the neck is designed to receive the wick assembly which will sit thereon.
The wick assembly includes the wick, which is preferably of a woven material, and a cover member, as previously mentioned, will include a flange which will seat on the top of the wall surrounding the aperture. Centrally of the cover member there will be a raised land portion with a lower portion surrounding the raised land portion. In the center of the raised land portion there will be provided an aperture for the wick to extend therethrough. The lower portion surrounding the raised land portion will include a drain
