Abstract
A pocket lighter in which the spark wheel which may produce sparks on rotating in a first direction and rubbing on the pyrophoric stone, apart from being rotatable, is movable between a first position in which it is blocked from rotating in the first direction, and a second position in which it may rotate in said first direction, producing sparks directed towards the valve. The wheel is urged towards said first position when being actuated to rotate in said first direction and to pass to said second position, said wheel should first be rotated in a direction opposite to said first direction. Preferably the positions of the spark wheel are associated with the positions of the end stubs of the shaft thereof in some housings.
Claims7
A pocket lighter comprising:
- a body defining a fuel reservoir for holding fuel and having open and closed positions;
- a valve for regulating opening and closing of the reservoir, and having an outlet port, wherein when the lighter is in a vertical position, said outlet port defines a fuel outlet level;
- a pyrophoric assembly disposed in the body and including a pyrophoric stone;
- a wheel including a multitude of exterior teeth;
- a rotary shaft supporting the wheel, and having first and second opposite ends;
- shaft housing means connected to the body and supporting the ends of the shaft and the wheel for movement between first and second positions;
- spring means supported by the body, engaging the pyrophoric assembly and urging said assembly against the wheel, wherein the pyrophoric assembly urges the wheel into the first position;
- wherein, when the shaft and the wheel are in the second position, the shaft supports the wheel for rotation against the pyrophoric stone, and the wheel is rotated in a first direction to rub the teeth of the wheel against the pyrophoric stone to generate sparks and to direct the sparks toward said valve;
- and
- wherein, when the shaft and the wheel are in the first position, the pyrophoric assembly engages the wheel and blocks the wheel from rotation in the first direction;
- and a force in a second direction, different from the first direction, must be applied to the wheel to move the wheel from the first position to the second position.
