Abstract
Abstract In a gas cigarette-lighter a device for adjusting the flame is provided in the form of spaced resilient lugs projecting from the bottom of the well formed at the upper portion of the gas reservoir constituting the body of the cigarette-lighter, said lugs being disposed concentrically at spaced angular intervals about the axis of the bore connecting the bottom of said well to the inner space of the reservoir. A tapered seat member movable within said well under the control of the valve body is adapted to cap said lugs and move same more or less towards one another thus modifying accordingly the cross-sectional passage for the gas and therefore the gas output.

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
173 words
Device for adjusting the flame of a gas cigarette-lighter of the type comprising a valve body screwed in a well formed at the upper portion of a gas reservoir constituting for example the body of the cigarette-lighter, in which the bottom of said well communicates with the inner space of said reservoir through a bore having, at least locally, a wick dipping in said reservoir, wherein said device comprises in combination on the one hand resilient lugs projecting from the bottom of said well and disposed concentrically and at spaced angular intervals about the axis of the bore connecting the bottom of said well to the inner space of said reservoir, and on the other hand a tapered seat member adapted to be moved longitudinally within said well by means of the valve body to which it is connected at least for translation, so as to cap said resilient lugs and move same more or less towards one another for modifying accordingly the crosssectional passage available for the gas and therefore its output.
Claim 2
Dependent Claim
173 words
Device for adjusting the flame of a gas cigarette-lighter of the type comprising a valve body screwed in a well formed at the upper portion of a gas reservoir constituting for example the body of the cigarette-lighter, in which the bottom of said well communicates with the inner space of said reservoir through a bore having, at least locally, a wick dipping in said reservoir, wherein said device comprises in combination on the one hand resilient lugs projecting from the bottom of said well and disposed concentrically and at spaced angular intervals about the axis of the bore connecting the bottom of said well to the inner space of said reservoir, and on the other hand a tapered seat member adapted to be moved longitudinally within said well by means of the valve body to which it is connected at least for translation, so as to cap said resilient lugs and move same more or less towards one another for modifying accordingly the crosssectional passage available for the gas and therefore its output.
Claim 3
Dependent Claim
38 words
Device as set forth in claim 1, wherein said tapered seat member is formed directly in the lower portion of said valve body, coaxially to said bore having its upper end adapted to be closed by a valve.
Claim 4
Dependent Claim
33 words
Device as set forth in claim 1, wherein said resilient lugs are connected at their roots to a common base and separated from one another by longitudinal slots disposed at spaced angular intervals.
Claim 5
Dependent Claim
56 words
Device as set forth in claim 1, wherein said resilient lugs have in cross-section and throughout their height the shape of a sector of an annulus and form together a cylindrical central cavity adapted to receive the upper end of said wick in order to regulate the gaseous flow by more or less throttling said wick.
Claim 6
Dependent Claim
87 words
Device as set forth in claim 1, wherein said resilient lugs have in cross-section, throughout their height, the shape of a circular sector disposed coaxially to a capillary orifice formed through the upper bottom of the bore receiving the upper end of said wick and permitting the passage of the gas escaping from said wick, whereby the gaseous output and therefore the flame of the cigarette-lighter can be adjusted by changing the conditions of flow of the gaseous fluid through the passages formed by said resilient lugs.
Claim 7
Dependent Claim
150 words
Device as set forth in claim 1, wherein said resilient lugs have in cross-section, through the major part of their height, the shape of a sector of an annulus, and at their upper portion the shape of a circular sector in order to form a cylindrical recess which, by constituting an extension of the cavity receiving said wick, is adapted to receive the upper end of said wick and is bounded at its upper end by a shoulder consisting of the innermost portions of the circular-sector shaped portions of the resilient lugs forming at this level a passage whereby the adjustment of the gaseous output which results from the relative movements of said lugs is due on the one hand to the more or less accentuated throttling of the upper end of the wick and on the other hand to a modification in the flow conditions obtaining through said passage.
