Abstract

Table lamp perfected, characterized essentially by the fact of comprising in its reed a transparent spherical cavity in its upper part equipped with a vertical cylindrical neck, provided at the upper end and two tubular branches communicating with each other, one of which forms a housing of double jacket for the bulb, which can be used as a heating element, while the other branch is joined to the upper edge of the aforementioned shirt by means of an arc pattern, the concavity of which is disposed downwards, and in the lower position of the opening of both branches a partition wall that has in its center a communication hole with an axial tube to the neck, whose tube reaches the top of the spherical cavity, according to an oblique capillary section, and provided this cavity filled with a liquid whose level reaches approximately up to the middle of the referred neck, existing said level and the mentioned wall enters an air chamber, and for p to expose the tubular upper part of the lamp, corresponding to the two communicating branches, filled with liquid, which is maintained in said tubular cavity thanks to the pressure of the aforementioned air chamber, and whose liquid corresponding to the upper frogs, it is displaced when expanding by the heat of the incorporated bulb, descending part of it and bubbles towards it. The spherical cavity, through the tubular passage that puts in communication both upper and lower parts of the system, producing simultaneously, the compression of the air in the chamber and a vacuum in the upper branches, which contributes to the rise of part of the liquid in the cavity spherical, towards the upper branches, whose liquid is able to be heated by the bulb to repeat this way the cycle.
