Abstract
A portable heating appliance having a member to be heated, includes burner tubes for heating the member; a fuel supply cartridge for supplying fuel to the burner tubes, the cartridge including a stationary fuel delivery valve for controlling the flow of fuel from the cartridge; and an actuator assembly for actuating the fuel delivery valve in response to user actuation to start the flow of fuel from the cartridge, the actuator assembly including a plunger, a mechanism for moving the plunger to a first position into operative engagement with the fuel delivery valve for opening the fuel delivery valve and a mechanism for moving the plunger to a second position out of operative engagement with the fuel delivery valve so that the latter terminates the flow of fuel to the burner tubes. The mechanism for moving the plunger to a second position incudes a pivotally mounted lever; a spring for biasing the lever in a first direction; a switch for biasing the lever in a second, opposite direction against the force of the spring; a ring secured to the plunger; and a slidably mounted shaft movable by the lever into engagement with the ring to move the plunger to the second position when the switch biases the lever in the second direction.
