Abstract
A hand held, flammable gas igniter includes a handle with a thumb activated trigger extending, out of the handle top, a child safety lock mounted in the handle bottom, a cylinder filled with a flammable gas enclosed within the handle and a hollow tube extending forward from the handle to deliver the gas, when ignited, to a desired location, such as charcoal in a barbecue or wood in a fireplace. When the child safety lock is activated the trigger is released so that it can move downward and forward into the handle causing an L-shaped rocker to pivot forward, opening a gas flow valve on the cylinder, delivering the flammable gas to the end of the hollow tube. The movement of the trigger also activates a piezoelectric spark generator, delivering an igniting spark to the gas at the end of the tube.
