Abstract

Abstract A lamp assembly includes a fuel tank with a lower portion for enclosing liquid fuel and an upper wick guide portion, with a burner affixed to the top of the wick. A globe extends above the burner. An ashtray rests on the fuel tank, or individual cigarette-supporting clips can be attached to a smoke hood just below apertures in the hood, with the ashtray positioned on the table within the hood. The smoke hood directs smoke rising from the ashtray unit to a location adjacent the flame for virtual dissipation of the smoke.

Claims Analysis

Total Claims: 4
Claim 1
Independent Claim 391 words
A smoke dissipating ashtray lamp, comprising: a fuel tank and wick guide assembly, having a lower receptacle portion for containing liquid fuel, an upper wick guide portion affixed to the lower portion, and wick adjusting means extending from a position within the upper wick guide portion of the fuel tank and wick guide assembly to facilitate vertical positioning of the wick; a burner assembly, including an uppEr portion defining an exit aperture for a wick, a central platform having an inner portion defining a multiplicity of small apertures to allow air to pass through and an outer portion defining a plurality of holes to direct the rising tobacco smoke closer to the flame location than would otherwise be possible, and a lower portion constructed to engage the upper portion of the fuel tank and wick guide assembly, which lower portion includes a threaded portion, and said upper wick guide portion of the fuel tank and wick guide assembly includes a tapped portion for mating engagement with said threaded portion of the burner assembly such that after the fuel tank and wick guide assembly is engaged with the burner assembly, the fuel tank and wick guide assembly is supported from the burner assembly; a smoke hood, having an upper channel portion, an intermediate portion defining a bead extending around its inner periphery such that said central platform of the burner assembly rests on said bead to support the burner assembly, and further defining a slot for the wick adjusting means, and a lower body portion, said lower body portion defining a plurality of apertures, and having a plurality of support ledges, each affixed just below one of said plurality of apertures in the smoke hood, to afford placement of a cigarette, cigar or pipe on one support ledge with the burning tobacco inside the smoke hood, so that the tobacco smoke passes upwardly and adjacent the burner assembly for substantial consumption in the flame area; a generally circular globe, having a lower cylindrical portion for fitting in the smoke hood, and an upper chimney portion which affords egress of the gases which pass upwardly from the ashtray through the smoke hood and the globe; and an ashtray, positioned within the bottom of the smoke hood and below the receptacle portion of the fuel tank and wick guide assembly, to catch falling ashes.
