Timepiece-gas lighter assembly

Claim 1

A unitary electronic digital display watch and liquefied gas-fueled lighter comprising a casing, a watch module mounted within said casing comprising a quartz oscillator, a digital display means for displaying a digital output, and circuit means for interconnecting said quartz oscillator with said digital display means for providing a readout representing the time, a d.c. power source connected to said watch module, and a first switch means connected to said watch module for interconnecting said power source with said watch module, a blocking oscillator, a second switch means for interconnecting said d.c. power source to said blocking oscillator, a step-up transformer having a primary winding and a secondary winding, said primary winding provided at the output of said blocking oscillator, said secondary winding connected to a spark-gap ignition circuit, said spark-gap ignition circuit comprising a pair of electrodes spaced apart to form a spark-gap, means for amplifying a pulse output across said secondary winding to a high-voltage pulse across said spark-gap of sufficient magnitude to ignite an ignitable gas appearing across said spark-gap, means for providing an ignitable gas across said spark-gap, diode means connected between said secondary winding and said pair of electrodes for preventing said high-voltage pulse from passing to said quartz oscillator, and means for positioning said digital display means and said spark-gap in said casing such that the light emitted by the ignited gas across said spark-gap is applied to said digital display means for providing a visual readout of said digital display means.
