The Advance Automatic.
This automatic burner, Fig. 18, is typical of the class having two magnets, one to open valve and light gas, and another to close valve and extinguish the light. It embodies an improvement over the older types of burners in that the binding posts are mounted on a rubber strip held by two screws, thus preventing the twisting and loosening so common heretofore. It also allows of the valve being opened and gas lighted by means of a match should the battery fail.
