Abstract
The invention has a container (50) for a fuel (W) with at least a partial cover (55) in which there is a non-combustible wick (52) in a wick holder (100). Above the container (50) near the wick holder there is at least one roller or upright body (RK) or in the container (50) there is a disc of solid fuel (W) around the wick holder (100), whereby the fuel of the roller and upright body (RK) or of the disc is melted by the flame and cover heat and collected by the container (50) and/or by the wick holder (100) as supplementary fuel. The wick holder (100) is suspended in an aperture (56) of the container cover (55), so that the wick holder (100) is not in direct heat-tansmitting contact with the container base (50b).
Claims38
In a paraffin lamp comprising a container (e.g. 50) for a fuel, at least partially covered by a cover (e.g. 55), inside of which is provided an incombustible wick (e.g. 52) inside a wick holder (e.g. 53, 100), the lamp further being adapted to receive a body of solid fuel which is positioned to be melted by heat from a flame and from the heated cover, and wherein at least one of the container (50) and the wick holder (100) is adapted to hold melted fuel to be taken up by said wick and burned, the improvement wherein
- at least one semi-spherical receptacle segment forming a solid fuel-holding recess (e.g. 108) is arranged above the container (50) in the cover (55) near to the wick or above the cover (55), said semi-spherical receptacle segment being shaped to accept the body made of solid fuel as a ball (RK), or
- wherein at least one roller channel (e.g. 66, 71) with a retainer catch (e.g. 64) is arranged above the cover (55) near to the wick, said roller channel (66, 71) being shaped to receive the body of solid fuel in the shape of a ball (RK).
A paraffin lamp with an incombustible wick (52) having a core (82) of a heat-resistant fiber material, preferably quartz glass fibers, and encompassed by a metal wire coil (83) and/or tube (84) of quartz glass, characterized in that the metal wire coil (83) and or the tube (84) are at least partly separated and/or provided with a heat insulation (86, 87) in the longitudinal direction of the wick to reduce the heat transfer between the combustion zone (BZ) at the upper end and the preheating and suction zone (VZ, SZ) at the lower end (FIG. 19 through 22).
