Abstract
Abstract In a lighter apparatus operable with a fuel controlled by a fuel valve actuated by means of an operating mechanism, a magnetic circuit for supplying energizing sparks to the fuel, the magnetic circuit comprising a substantially U-shaped yoke member, an armature member shunting the yoke member and supported in magnetic circuit relationship therewith, a torsion bar fixedly coupled to the armature member and connecting same to the common operating mechanism, the torsion bar being coupled to the armature member at a side portion thereof permitting rotation of the armature member away from the yoke member about an axis passing outside of the armature member, when the common operating mechanism is actuated. In another embodiment of the present invention the torsion bar is not fixed to the armature member but engages same with a leverlike or cam-shaped end portion and moves it against a backing member attached to the yoke member.

Claims Analysis
Total Claims: 12
Claim 1
Independent Claim
115 words
In a lighter apparatus operable with a fuel controlled by a fuel valve actuated by means of an operating mechanism, a magnetic circuit for supplying energizing sparks to said fuel, said magnetic circuit comprising a substantially U-shaped yoke member, an armature member shunting said yoke member and supported in magnetic circuit relationship therewith, a torsion bar means being in driving connection with said armature member and being in driven connection from said operating mechanism, said torsion bar means being disposed adjacent a side portion of said armature member permitting rotation of said armature member away from said yoke member about an axis passing outside of said armature member, when said common operating mechanism is actuated.
Claim 2
Dependent Claim
115 words
In a lighter apparatus operable with a fuel controlled by a fuel valve actuated by means of an operating mechanism, a magnetic circuit for supplying energizing sparks to said fuel, said magnetic circuit comprising a substantially U-shaped yoke member, an armature member shunting said yoke member and supported in magnetic circuit relationship therewith, a torsion bar means being in driving connection with said armature member and being in driven connection from said operating mechanism, said torsion bar means being disposed adjacent a side portion of said armature member permitting rotation of said armature member away from said yoke member about an axis passing outside of said armature member, when said common operating mechanism is actuated.
Claim 3
Dependent Claim
36 words
The combInation as claimed in claim 1, wherein said armature member has an elongated shape having an edge portion at a side thereof adjacent said yoke member, said torsion bar being coupled to said edge portion.
Claim 4
Dependent Claim
15 words
The combination as claimed in claim 2, wherein said axis passes through said torsion bar.
Claim 5
Dependent Claim
29 words
The combination as claimed in claim 1, wherein a gap is formed between said yoke member and said armature member when said armature member is rotated about said axis.
Claim 6
Dependent Claim
109 words
In a lighter apparatus operable with a fuel controlled by a fuel valve actuated by means of an operating mechanism, a magnetic circuit for supplying energizing sparks to said fuel, said magnetic circuit comprising a substantially U-shaped yoke member, an armature member shunting said yoke member and supported in magnetic circuit relationship therewith, a torsion bar means connected to said operating mechanism, backing means attached to said yoke member and having a flared-out portion, said torsion bar means having a portion operable to engage said armature member at a side portion thereof thereby moving said armature member away from said yoke against said flared-out portion of said backing means.
Claim 7
Dependent Claim
109 words
In a lighter apparatus operable with a fuel controlled by a fuel valve actuated by means of an operating mechanism, a magnetic circuit for supplying energizing sparks to said fuel, said magnetic circuit comprising a substantially U-shaped yoke member, an armature member shunting said yoke member and supported in magnetic circuit relationship therewith, a torsion bar means connected to said operating mechanism, backing means attached to said yoke member and having a flared-out portion, said torsion bar means having a portion operable to engage said armature member at a side portion thereof thereby moving said armature member away from said yoke against said flared-out portion of said backing means.
Claim 8
Dependent Claim
15 words
The combination as claimed in claim 1, wherein said armature member has an elongated shape.
Claim 9
Dependent Claim
35 words
The combination as claimed in claim 5, wherein a gap is formed between said yoke member and said armature member when said armature member is moved away towards said flared-out portion of said backing means.
Claim 10
Dependent Claim
16 words
The combination as claimed in claim 5, wherein said backing means is made from nonmagnetic material.
Claim 11
Dependent Claim
22 words
The combination as claimed in claim 5, wherein said portion of said torsion bar means is in the form of a lever.
Claim 12
Dependent Claim
23 words
The combination as claimed in claim 5, wherein said portion of said torsion bar means is in the form of a cam means.
