DESCRIPTION:
BRIEF SUMMARY
The present invention relates to a lamp for liquid fuel comprising a fuel container, a burner connected to an opening in the container and a drawing up means, preferably a wick, connected to the container, such that fuel can be led by means of capillary forces from the container to the burner, in addition to which there is present a frame arrangement enabling the lamp to be stood or suspended.
Lamps for liquid fuel such as paraffin and other oil fractions have been known for some considerable time. They consist of a fuel container and a burner with some form of drawing up means for the fuel, usually in the form of a wick. The lamp can also include some kind of frame and a shade for the flame in the burner. Whereas in former times they represented an important source of lighting, lamps of this type, which are commonly known as oil lamps, are now used widely in the industrialized countries as decorative lighting, or `lights to provide atmosphere`. In professional applications, for example in restaurants, where both financial and rational criteria are applied, the oil lamp has proved to be an easily handled means which, in comparison with candles, offers lower operating costs and easier maintenance and cleaning.
In professional use especially in restaurants there are high demands according to a rational and safe handling. It is very important that the liquid fluid not will bring bad smell or taste to food stuff. Of great importance is that the lamps by filling the fuel and by their use will bring as little risk as possible for fire in the inflameable fuel. As the until now used lamps of this type are based on old designs they will not fulfil high demands in said respect.
The object of the invention is to propose a lamp for liquid fuel in which handling and maintenance operations have been further simplified and made more economical in relation to previously disclosed models of such lamps.
A further object of the invention is to propose a lamp of the aforementioned kind which can be manufactured at low cost and which can easily be given a wide range of external appearances within the scope of a common technical principle.
The object of the invention is achieved through the lamp being characterized in that the container is of the disposable type and is equipped not only with connecting organs for the purpose of securing it in the frame arrangement, but also with securing organs for the wick support, and in that the frame arrangement is so executed as to accommodate the burner inside it in such a way as not to be visible in the main from outside the lamp in its operating position and is so arranged as to permit essentially only the part of the container with said opening to pass through to the outside, so that the wick support, when it is connected to the container, will be on the outside of the frame arrangement, in connection with which the frame arrangement should preferably exhibit means for supporting a shade, such that the latter encloses the burner and the intended flame.
Two embodiments of the lamp in accordance with the invention are shown in the accompanying drawings.
FIG. 1 shows a vertical section through the centre of the lamp in its first embodiment;
FIG. 2 shows a part of the same section, but on an enlarged scale;
FIG. 3 shows a view from above taken from the line III--III in FIG. 2;
FIG. 4 shows the second embodiment in the same section as in FIG. 2; and
FIG. 5 shows the lamp in side view.
In accordance with FIG. 1 the lamp exhibits a functional part 1 and a decorative part 2. The functional part 1 comprises a container 3 for liquid fuel and a wick support 4, which supports a wick 5 hanging down into the container 3. More precisely, the container 3 consists of a container component 6 which, via a breast 7 is transformed into a neck 8. In accordance with FIG. 2 and FIG. 3, the neck exhibits a lip around the edge of an opening 9. This lip is used to retain a cover 10 for the container. The cover has an edge part 11 with three projecting parts 19 facing in a downward and outward sense, each of whic
