Definitions

  • 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.
  • 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. 1
  • the present invention relates to a lighter and more particularly to the means actuating the magnetic circuit of a pocket size lighter where economy-of space is of prime importance.
  • the above-mentioned:copending application is concerned with a' lighter in which a common. operating mechanism actuates a fuel valve and the magnetic ignition system and in which a time delay of the ignition time with respect to the opening of the fuel valve isattained by means of a torsion rod acting as a force translating member between the operating mechanism and the ignition system.
  • themake-and-break' type magnetic ignition system is provided-with anarmature1whichswings away sideways from the yoke member.
  • armature 2 At one longitudinal edge thereof a torsion bar 3 is attached which is journaled in supports 31 and 32 and couples the armature to an operating'mechanism of the lighter (not shown) which is common to the fuel v'alve (not shown) and to the magnetic ignition system.
  • Armature 2 in virtue of its attachment to torsion bar 3 is rotatable about the axis passing through torsion bar 3,"that is, aboutan axis located parallel withits outer edge.
  • the make-and-break magnetic system includes a yoke l and armature 2.
  • a backing member 4 is attachedto the side of yoke l and has a flared-out portion 42 against-which the armature abuts when sideways moved from torsion bar 3.
  • the torsion bar 3 inthe present embodiment is not fixedly coupled to armature 2, but is journaled on supports 3l' and 32,
  • the backing member 4 is slightly curved at 41 which enables the armature 2 to roll away from yoke l.
  • a torsion bar connectsthe armature withtheoperating mechanismand the torsion bar is coupled to thearmature at onesideedge thereof whereby an axis of rotation-is formed about the side edge of the armature.
  • the axis of rotation of the armature is placed outside of the armature by providing a backing means on the yoke member against which the armature can be moved sideways or rotated .to abut'against such backing means.
  • the backing-means is preferably made from a nonmagnetic material.
  • the torsion bar in the latter embodiment is provided with a leverlike or'cam-shaped portion which engages the armatureto move or rotate same against the backing means.
  • FIG. 1 illustrates a make-and-break type magnetic system in which the armature is fixedly coupled to a torsion bar;
  • FIG. 2 illustrates the support of the armature of the magnetic system according to FIG. ljon the torsion bar
  • H6. 3 illustrates a magnetic system similar to FIG. 1 in' which a torsion bar is operatively coupled to the armature;
  • FIG. 4 is a fragmentary plan view of the yoke, torsion bar, armature and of a backing means of the system of FIG. 3.
  • said 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 torsionrbar means being in driving connection withsaid armature member and beingin driven connection from said'operating mechanism, said torsion bar means being.
  • 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 connectedjto said operating,
  • 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 yokeagainst said flared-out portion of said backing means.
