Abstract

Abstract A lighter of the liquified gas fuel type having a case containing a fuel reservoir and a wick for conducting fuel to a normally closed valve operatively associated with an extensible conduit having an orifice at its outer end together with spark generating means and a valve actuator, the actuator being arranged to move the valve to an open position to permit gaseous fuel to enter the extensible conduit which in the retracted position permits the gaseous fuel to be ignited by the spark generating means and which may be extended telescopically to locate the burner orifice at the other end of the conduit in a location remotely spaced from the case for positioning the flame adjacent an area of limited access.

Claims Analysis

Total Claims: 8
Claim 1
Independent Claim 137 words
A gas-fueled lighter of the type having a case, a fuel reservoir in said case and spark generating means for igniting vaporized fuel from said resErvoir the improvement which comprises, valve means in said case movable between an open and a closed position, wick means disposed in wicking relationship with the fuel in said reservoir and communicating with said valve means, means for manually moving said valve means between said open and closed positions, an extensible conduit supported on said case, said conduit having one end in operative communication with said valve means and a burner orifice at its other end, said conduit being movable between a retracted position with said burner orifice in igniting relationship with said spark generating means and an extended position to locate said burner orifice in a remote relationship with said case.
Claim 2
Dependent Claim 137 words
A gas-fueled lighter of the type having a case, a fuel reservoir in said case and spark generating means for igniting vaporized fuel from said resErvoir the improvement which comprises, valve means in said case movable between an open and a closed position, wick means disposed in wicking relationship with the fuel in said reservoir and communicating with said valve means, means for manually moving said valve means between said open and closed positions, an extensible conduit supported on said case, said conduit having one end in operative communication with said valve means and a burner orifice at its other end, said conduit being movable between a retracted position with said burner orifice in igniting relationship with said spark generating means and an extended position to locate said burner orifice in a remote relationship with said case.
Claim 3
Dependent Claim 41 words
A gas-fueled lighter in accordance with claim 1 wherein said extensible conduit comprises a plurality of tubular sections arranged in telescopic relationship, said plurality of tubular sections including an upper section having an open upper end for forming said burner orifice.
Claim 4
Dependent Claim 84 words
A gas-fueled lighter in accordance with claim 2 wherein said extensible conduit includes a flexible tube disposed within said tubular sections, said flexible tube having an inner end connected in communication with said upper section and a lower end connected in communication with said valve means adjacent said conduit one end, said flexible tube being arranged to collapse in said retracted position of said conduit and to extend in the extended position for conducting vaporized fuel from said valve means to said burner orifice.
Claim 5
Dependent Claim 93 words
A gas-fueled lighter in accordance with claim 3 wherein said case composes side walls, end walls, a bottom wall and a top wall defining an interior and including a vertically extending enclosure for said extensible conduit disposed in said case interior, said enclosure defining a cavity having an upper end opening into said case top wall, means on the inner wall of said enclosure for supporting said conduit centrally in said enclosure whereby said burner orifice is positioned adjacent the open upper end of said cavity in the retracted position of said conduit.
Claim 6
Dependent Claim 108 words
A gas-fueled lighter in accordance with claim 4 wherein said valve means including means for normally urging said valve means into said closed position and wherein said valve moving means include lever means operatively connected at one end with said valve means, said lever means including a manually operable lever pivotally mounted on said case top wall adjacent said spark generating means, said lever being pivotally movable into one position to permit said valve means to be maintained in said closed position and said lever being pivotally movable into a second position by an operator to move said valve means into an open position against said urging means.
Claim 7
Dependent Claim 22 words
A gas-fueled lighter in accordance with claim 5 including means on said case for releasably retaining said lever in said second position.
Claim 8
Dependent Claim 27 words
A gas-fueled lighter in accordance with claim 6 including illuminating means on said case for providing a beam of light extending upwardly from said case top wall.
