Abstract
A gaseous lantern ventilator including an outer shell concentrically spaced over an inner metal liner which collects and exhausts the hot gases from the burner assembly through a chimney, the upper end of which is surrounded by an annular opening in the outer shell. The rising hot gases will entrain outside cool air drawn between the shell and liner, thereby cooling the liner and substantially reducing the surface temperature of the outside shell.
Claims15
In a hydrocarbon fuel lantern structure including a globe and burner assembly, the improvement comprising a ventilator assembly including:
- an outer shell which is circular in shape converging upwardly toward an open end;
- a liner concentrically spaced within the outer shell, defining an annular space therebetween, the liner having a circular shape converging upwardly and terminating in an open end which lies in a plane approximate to the plane of the open end of the outer shell;
- bracket means on the liner supporting said ventilator assembly on the lantern globe and burner assembly;
- and
- connector means attaching the liner to said outer shell.
In a hydrocarbon fuel lantern structure including a globe and burner assembly, the improvement comprising a ventilator assembly including:
- an outer shell with its lower section shaped as a conical frustum and the upper section shaped as an open-ended stack;
- a liner concentrically spaced within the outer shell, defining a space therebetween, the upper portions of the liner being shaped as a chimney with its open end terminating in a plane approximate to the plane of the open end of the outer shell;
- bracket means on the liner supporting said ventilator assembly on the lantern globe and burner assembly;
- and
- connector means attaching the liner to said outer shell.
A hydrocarbon fuel lantern including:
- a burner assembly;
- a globe positioned on the burner assembly;
- a ventilator assembly positioned on the burner assembly and globe comprising:
- an outer shell converging upwardly and terminating in an open end;
- a liner concentrically spaced within the outer shell, defining a space therebetween, a portion of the liner being shaped as a chimney with its open end terminating in a plane approximate to the plane of the open end of the outer shell;
- bracket means on the liner supporting said ventilator assembly on the lantern globe and burner assembly;
- and
- connector means attaching the liner to said outer shell.
In a hydrocarbon fueled lantern including a globe, a burner assembly and a ventilator assembly, the improved ventilator assembly including:
- an outer shell with an open lower section and an open upper section, said open upper section comprising a substantially smaller area than said lower section;
- a non-combustible liner surrounding the burner assembly, said liner being concentrically spaced within the outer shell defining a space sufficiently great therebetween to permit essentially free flow of air, the upper portions of the liner being shaped as a chimney with its open end terminating in a plane approximate to the plane of the upper open end of the outer shell;
- bracket means on the liner supporting said ventilator assembly on the burner assembly and cooperating to maintain the position of the lantern globe;
- and
- connector means attaching the liner to said outer shell.
