10 Claims. (Cl. (B7-7) This invention relates to catalytic lighters for the purpose of enabling the united sleeve and cigarettes and the like, wherein vaporizable fluid holder to t tightly, though removably, within carried by absorbent material is caused to co-act the casing. The holder 6 has an inturned flange with a catalytic element in the presence of air, 8 at its outer end, to retain the catalytic eleto thus render such catalytic element incandesment, which appears here in the form of a blockv 5 cent, so that a cigarette or the like applied thereor pellet 9 of spongy platinum composition, havto and drawn upon, may be ignited. ing an aperture I0 therethrough.

Also this air-tight closure means prevents evaporation of the fuel.

The casing I is also provided with a bayonet slot 2'I, and the holder 6 bears a protuberance 28 that is adapted to engage said slot to localize the holder, with the connected sleeve 3, and to lock them, in the operative position.

Variations within the spirit and scope of my invention are equally comprehended by the foregoing disclosure.

I claim:-

l. A lighter comprising a casing, a sleeve removably fitting said casing, absorbent material, to be saturated with vaporizable fuel, contained within said sleeve, a hollow holder axially and removably engaging said sleeve, a catalytic element carried by said holder in spaced relation with the absorbent material in said sleeve, and admission means enabling a ow of atmospheric air to pass lengthwise entirely through said absorbent material, toward the catalytic element, to convey fuel thereto.
