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.
Vibrator Burner.
This is an automatic burner which has no valve mechanism, but ignites the gas only. It is generally placed in a cluster or ring where the burners are close enough to light by contagion. It is much smaller in diameter than the regular automatic burners, being but one and three-quarter inches in diameter.
Argand Automatic Burners.
Automatic burners are also made for Argand, but present no radical difference in construction over the regular type.
