Abstract
Abstract A wick holder for a liquid-fuel burning lamp comprises a support (3) in the form of a circular button-like metal pressing formed to be a press-fit in the neck (2) of a fuel containing receptacle (1). Support (3) comprises a central portion with an apertured central portion (4) the contour of which is constituted by inwardly projecting fingers (5) and is pressed out to form a projection (10) from the remainder of the support (3). A wick tube (6) which may be either plane or beaded is pressed through the aperture (4) to engage the fingers (5) so that the fingers elastically grip the tube (6) in a desired axial position and a wick (8) extends through the tube (6) into the fuel within container (1).

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
114 words
A wick holder for a liquid-fuel burning lamp comprises a wick support in the form of a button-like metal pressing formed to be a press-fit in the neck of a liquid-fuel containing lamp, the centre of the pressing being formed with an aperture presenting radially inwardly projecting fingers, and a wick tube of heat resisting material forced partly through the aperture so that the fingers flex as the tube is pushed through and by their own elasticity grip the tube frictionally and hold it in a desired axial position in the wick support, the fingers being spaced apart around the aperture to permit air flow therethrough when the tube is gripped by the fingers.
Claim 2
Dependent Claim
