Abstract
A torch igniter for attachment to a torch nozzle having a nozzle tip through which a fuel is passed includes an igniter attachment on which a flint and abrading wheel is mounted. The flint is biased against the rim of the abrading wheel at a location thereon generally facing the nozzle tip so that rotation of the wheel generates sparks which are projected in front of the nozzle tip to ignite the fuel passing therefrom. A small electric or pneumatic motor may be connected to the flint wheel to rotate the wheel upon energization of the motor. Compressed gas fed to the torch nozzle may be utilized to drive the pneumatic motor; electric batteries are provided in the case of an electric motor. The igniter attachment is fixedly positioned rearwardly of the nozzle tip and laterally offset therefrom so that the attachment and motor are not adversely affected by the flame.
