As shown in the il-lustration these couplers operate in the ordinary way and areinterchangeable with other makes. When coupled the joints maybe locked by driving the wedge of one coupler over the toe ofthe other. The wedges are drop forgings held in place bysprings, and the ends are upset to secure them to the Steam Hose Coupler with Positive Locl< and Safety Trap Xulcabeston gaskets of the oscillating type developed by thiscompany have been used, and the couplers are equipped withgravity traps. The trap valves are designed to remain seatedwhile under pressure and to open by gravity when the pressureis released, thus draining the hose connections of all conden-sation, and serving as a protection against scalding when dis-connecting the couplings. FUEL OIL BURNER A fuel oil burner so arranged that the oil is atomized andmixed with air outside of the burner has been developed byH. B. Stilz, 1938 North Marvine street, Philadelphia, Pa. Thearrangement of the parts of the burner is shown in the sec-tional drawing. Oil under 50 lb. pressure enters an innernozzle through the small pipe shown at the top of the the orifice is a spiral which gives the oil a rapidlywhirling motion, thus causing it to spread out in a cone-shaped film as it leaves the burner.
