Abstract
A vortex type gas lamp comprising a base and an axially extending-transparent shield. Gas is supplied near the bottom end of the shield. The shield is formed of a plurality (preferably two) axial curved sections which overlap one another at their axial edges to form tangentially directed port. Combustion of the gas with atmospheric oxygen admitted through the ports results in an axial vortex of burning gas useful for illumination, decoration and heat.
Claims10
A vortex type gas lamp, said lamp having a base end and a top end, and a central axis extending from said base end to said top end, said top end being open, said lamp comprising:
- a shield comprising a first and a second axially extending section, said sections being substantially identical, each section being transparent to light, and constituting a wall with an inner surface and an outer surface, each said section having a first and second axially edge extending from end to end,
- said first and second walls alternately overlapping one another so as to form respective axially extending ports formed by the outer surface of one section and the inner wall of its neighbor section, said ports being tangentially directed into the shield in the same rotational sense.
