Title: Gas lighter with single spark igniter - produces number of sparks in close succession at each operating sequence
IPC: F23Q3/00
Filed: 1976-06-14
Abstract: A gas igniter has an electrical circuit which is conventional and produces a single spark impulse from a battery, primary and secondary coil with a capacitor and contact breaker. At each spark application however, the contact points (13) act under the spring (16) and move the carrier (14) from right to left in the housing (15). This moves a row of bosses (13) over the contact (12) carried on the lever (9). The contact breaker points therefore produce 3 sparks at each ignition sequence. This increases the chances of providing an adequate spark for the ignition of the equipment.
