Abstract

Abstract A lighter and fuel reservoir is disclosed in which the fuel utilized is a liquified gas. The lighter is characterized by a deformable valve assembly which controls the flow of gaseous fuel to a burner where it is ignited by a spark generator. The flow of fuel from the valve is activated by a spring urged slide member moved linearly although the user rotates the finger piece controlling the slide member. The flow of fuel from the reservoir to the valve assembly is controlled by a fuel regulator which includes a compressible porous member and a metallic piston, the piston acting as a heat reservoir to prevent unequal fuel flow and flame flare-up which may otherwise occur when the lighter is held in an inverted position.

Claims Analysis

Total Claims: 9
Claim 1
Independent Claim 210 words
A lighter of the type using liquified gas as a fuel, said lighter comprising: a housing; a fuel reservoir in said housing for holding a supply of fuel; a burner; deformable valve means connected to said reservoir and said burner and adapted to be opened to permit the escape of gaseous fuel from said reservoir to said burner; a valve activating mechanism adjacent said valve means controlling the opening and the closing of said deformable valve means; a generator for a spark to ignite fuel escaping from said burner when said valve is in an open position; said deformable valve means including a valve member made of resilient material contained within a recess in said housing, said member having a valve opening therethrough connected to said reservoir; said valve activating mechanism including a slide member overlying the valve opening whereby when said mechanism is in an at-rest position the valve opening is sealed by said member; and said valve activating mechanism further including a rotary mounted finger piece operatively connected to the slide member whereby rotary motion of the fingerpiece provides linear motion to the slide member and said member is adapted to be moved from sealing relation with the valve opening and the burner is positioned adjacent said opening.
Claim 2
Dependent Claim 210 words
A lighter of the type using liquified gas as a fuel, said lighter comprising: a housing; a fuel reservoir in said housing for holding a supply of fuel; a burner; deformable valve means connected to said reservoir and said burner and adapted to be opened to permit the escape of gaseous fuel from said reservoir to said burner; a valve activating mechanism adjacent said valve means controlling the opening and the closing of said deformable valve means; a generator for a spark to ignite fuel escaping from said burner when said valve is in an open position; said deformable valve means including a valve member made of resilient material contained within a recess in said housing, said member having a valve opening therethrough connected to said reservoir; said valve activating mechanism including a slide member overlying the valve opening whereby when said mechanism is in an at-rest position the valve opening is sealed by said member; and said valve activating mechanism further including a rotary mounted finger piece operatively connected to the slide member whereby rotary motion of the fingerpiece provides linear motion to the slide member and said member is adapted to be moved from sealing relation with the valve opening and the burner is positioned adjacent said opening.
Claim 3
Dependent Claim 36 words
A lighter as defined in claim 1 wherein the burner is mounted on said slide member so that when the burner is aligned with the valve opening fuel may escape through said burner from said opening.
Claim 4
Dependent Claim 39 words
A lighter as defined in claim 2 wherein said slide member has a spring portion connected to said finger-piece, said spring portion urging the fingerpiece to an at-rest position whereby the valve opening is sealed by the slide member.
Claim 5
Dependent Claim 45 words
A lighter as defined in claim 3 wherein the slide member has a fulcrum thereon and said fulcrum is fitted into a recess on the fingerpiece whereby rotary motion of the fingerpiece cams the fulcrum so that linear motion is imparted to the slide member.
Claim 6
Dependent Claim 57 words
A lighter as defined in claim 4 wherein the spring portion is integral with the slide member and is connected at its end away from the slide member to the fingerpiece whereby in the at-rest position the spring urges the fingerpiece in a rotational direction opposite to that required to align the burner with the valve opening.
Claim 7
Dependent Claim 39 words
A lighter as defined in claim 5 wherein the slide member is made of a spring-like metal and exerts a downward pressure against the valve member to seal the valve opening when the fingerpiece is in an at-rest position.
Claim 8
Dependent Claim 27 words
A lighter as defined in claim 6 wherein the slide member prior to assembly in the lighter is normally depressed at a slight angle to the horizontal.
Claim 9
Dependent Claim 33 words
A lighter as defined in claim 6 wherein said slide member overlies the housing and a projection thereon contacts said member and with the valve member provides the primary support for said member.
