Total Claims: 15
Claim 1
Independent Claim
237 words
A camping stove comprising, in combination: a. a pan support; b. a base member having an aperture; c. a burner unit attached to said pan support; d. an air/gas mixture tube; e. a gas jet fitment extending through said base member aperture; f. first co-operating connection means on said air/gas mixture tube and said gas jet fitment clamping said base member between said air/gas mixture tube and gas jet fitment and enabling said mixture tube and said gas jet fitment to be connected together; and g. second co-operating connection means on said air/gas mixture tube and said burner unit enabling said mixture tube and said burner unit to be connected together in alternatively arrangeable conditions of said stove parts in which in an assembled condition, said burner unit and said pan support are mounted by said air/gas mixture tube on said base member for supporting and heating an article to be heated, and, in a demounted condition said pan support and said base member together form a closed casing for containing and protecting from damage said gas jet fitment, said air/gas mixture tube and said burner unit, said first and second co-operating connection means enabling said gas jet fitment, said mixture tube and said burner unit to be interconnected with each other and the casing when the stove is demounted to prevent said gas jet fitment and said mixture tube from being displaceable from within the casing.
Claim 2
Dependent Claim
237 words
A camping stove comprising, in combination: a. a pan support; b. a base member having an aperture; c. a burner unit attached to said pan support; d. an air/gas mixture tube; e. a gas jet fitment extending through said base member aperture; f. first co-operating connection means on said air/gas mixture tube and said gas jet fitment clamping said base member between said air/gas mixture tube and gas jet fitment and enabling said mixture tube and said gas jet fitment to be connected together; and g. second co-operating connection means on said air/gas mixture tube and said burner unit enabling said mixture tube and said burner unit to be connected together in alternatively arrangeable conditions of said stove parts in which in an assembled condition, said burner unit and said pan support are mounted by said air/gas mixture tube on said base member for supporting and heating an article to be heated, and, in a demounted condition said pan support and said base member together form a closed casing for containing and protecting from damage said gas jet fitment, said air/gas mixture tube and said burner unit, said first and second co-operating connection means enabling said gas jet fitment, said mixture tube and said burner unit to be interconnected with each other and the casing when the stove is demounted to prevent said gas jet fitment and said mixture tube from being displaceable from within the casing.
Claim 3
Dependent Claim
261 words
A camping stove comprising, in combination: a. a pan support; b. a base member having an aperture; c. a burner unit attached to said pan support; d. an air/gas mixture tube; e. an externally threaded gas jet extending through said base member apertUre; f. an externally threaded portion provided at one end of said air/gas mixture tube and an internally threaded portion provided within the other end of said air/gas mixture tube for connection to said gas jet; and g. a first internally threaded, coaxially disposed aperture provided in one end of said burner unit, which first aperture communicates with the interior of the burner unit, and a second internally threaded, coaxially disposed, blind aperture provided in the other end thereof, the threads of said first and second apertures and the external thread of the mixture tube being the same, the components of the stove being alternatively arrangeable in an assembled condition whereby said mixture tube is screwed into and communicates with said first aperture, said burner unit and said pan support being carried by said mixture tube on said base member for supporting and heating an article to be heated, and in a demounted condition in which the pan support and said base member together form a closed casing for containing and protecting from damage said gas jet, said mixture tube and said burner unit, said mixture tube being screwed into said second, blind aperture and the gas jet being retained by the mixture tube to prevent said mixture tube and said gas jet from being displaceable within the casing.
Claim 4
Dependent Claim
261 words
A camping stove comprising, in combination: a. a pan support; b. a base member having an aperture; c. a burner unit attached to said pan support; d. an air/gas mixture tube; e. an externally threaded gas jet extending through said base member apertUre; f. an externally threaded portion provided at one end of said air/gas mixture tube and an internally threaded portion provided within the other end of said air/gas mixture tube for connection to said gas jet; and g. a first internally threaded, coaxially disposed aperture provided in one end of said burner unit, which first aperture communicates with the interior of the burner unit, and a second internally threaded, coaxially disposed, blind aperture provided in the other end thereof, the threads of said first and second apertures and the external thread of the mixture tube being the same, the components of the stove being alternatively arrangeable in an assembled condition whereby said mixture tube is screwed into and communicates with said first aperture, said burner unit and said pan support being carried by said mixture tube on said base member for supporting and heating an article to be heated, and in a demounted condition in which the pan support and said base member together form a closed casing for containing and protecting from damage said gas jet, said mixture tube and said burner unit, said mixture tube being screwed into said second, blind aperture and the gas jet being retained by the mixture tube to prevent said mixture tube and said gas jet from being displaceable within the casing.
Claim 5
Dependent Claim
26 words
A stove according to claim 2, in which the pan support and the base member are generally bowl shaped and of the same shape and size.
Claim 6
Dependent Claim
54 words
A stove according to claim 3, in which the peripheries of the pan support and base member are castellated, the size and number of the castellations being such that the peripheries of the pan support and base member interfit with each other when they are placed together in the demounted condition of the stove.
Claim 7
Dependent Claim
24 words
A stove according to claim 2, in which the threads of the external and internal threaded portions of the mixture tube are the same.
Claim 8
Dependent Claim
