Abstract
Abstract A lamp having a wick carrier which floats on the liquid fuel and carries one or more wicks partly immersed in the fuel, characterized by the feature that a bladed rotor is mounted on the wick carrier and is constructed and arranged to be axially or radially impacted by the thermal airflow of the lighted wick or wicks and to rotate the wick carrier.

Independent Claim
63 words
In a wick lamp, a wick carrier adapted to float on liquid fuel and retaining at least one wick which is to be partly immersed in said fuel; a bladed rotor mounted on said wick carrier and arranged to be axially or radially impacted in use by the thermal airflow of each said wick when lighted so as to rotate said wick carrier.
Claim 2
Dependent Claim
63 words
In a wick lamp, a wick carrier adapted to float on liquid fuel and retaining at least one wick which is to be partly immersed in said fuel; a bladed rotor mounted on said wick carrier and arranged to be axially or radially impacted in use by the thermal airflow of each said wick when lighted so as to rotate said wick carrier.

A lamp according to claim 1, wherein said wick carrier is centrally mounted on an axle so as to be rotatable thereon.
Claim 4
Dependent Claim
46 words
A lamp according to claim 1, wherein each said wick comprises an external metal wire spiral having spaced apart spiral convolutions, surrounding a non-combustible absorbent wick material, and one or more metal heat conductors embedded in the wick material and extending parallel to the wick axis.
Claim 5
Dependent Claim
38 words
A lamp according to claim 1, wherein said wick carrier is open at its top and has in the outer edge and spaced above the carrier base, vertically extending outwardly directed radial blades being arranged in a circle.

Claim 7
Dependent Claim
34 words
A lamp according to claim 4, in which said wick is centrally retained in the wick carrier and around which an endless conical ring circle forming a heat conducting device is located with spacing.
Claim 8
Dependent Claim
46 words
A lamp according to claim 1, wherein said axially impactable rotor is cage-like and is mounted on said wick carrier and has curved blades with slit inwardly angled ends which are inserted and hooked in position in slots provided in the edge of the wick carrier.
Claim 9
Dependent Claim
29 words
A lamp according to claim 1, wherein a lateral edge of said wick carrier groove-like notches for receiving the wicks are provided in the regions of inwardly facing bevels.
Claim 10
Dependent Claim
54 words
A lamp according to claim 1, including a lamp body which is translucent and has a lower part which forms a reservoir for fuel and an upper part which is open at the top in the manner of a wind light; and in which lateral air inlet apertures are provided in the lamp body.
Claim 11
Dependent Claim
37 words
