Abstract: A torch handle is provided which includes a mechanism for locking the valve in the closed position. An actuator collar is positioned to be manually actuable with one hand to a forwardmost or open position. The quick-disconnect coupling assembly has a coupling collar, which may be retracted to remove a torch tip and thereby moves the actuator collar to return the valve to the closed position.

Abstract: A torch tip for burning an oxidizer/fuel combustible mixture includes a head having multiple burners so as to produce a plurality of flames. The torch tip includes a venturi acting as a jet pump using fuel metered through an orifice to draw an oxidizer in the form of air entering from cross passages into the venturi and then into a mixing chamber in the torch tip. The combustible mixture then exits into the burners through flameholders which impart a swirling motion to the combustible mixture so that more complete combustion and a higher temperature is achieved. Each flameholder also includes a bluff body portion thereon for causing eddying of the combustible mixture in the burners, thereby further enhancing flameholding and completeness of combustion.

Abstract: A cam-actuated valve is provided which includes a valve chamber having a poppet valve therein. A diaphragm separates the exterior of the valve body from fluid contained within the valve chamber. An actuator sleeve is positioned on the body for rotational and longitudinal motion. The vlave sleeve is spring-biased into a closed or "off" position by moving the actuator sleeve against the biased spring and rotating the spring about thirty degrees. The valve is moved to the "open" position. A cam forces a ball to move in a radial direction so as to open the poppet of the valve and thereby allow fluid to flow from an inlet to an outlet through the valve assembly. Locking means are provided whereby the valve is locked in the closed position.
