Abstract From the Canadian patent

Disclosed is an improved gaslighter structure using a flint for striking flame. To facilitate the assembling work so as to permit automatic assembling, the gaslighter structure uses a mount which is designed to permit the assembling of parts into a flame-striking device and the connecting of the flame-striking device to related parts for synchronizing the flame-striking operation with the ejection of petroleum gas from the nozzle assembly by simply mounting the parts to the mount at selected portions. Then, the mount with the flame-striking device and associated parts is push-fitted to the lighter housing.
