George K Cooke has made certain improvement in to a class of gas burner which are also known as self lighters.

The use of the spring used to be a liability and the same was done away with and a mechanical valve was introduced to make it easier to control the flame of the auxiliary jet. This made the device more reliable and easy to use. Moreover, the manufacturing process was simplified and production became cheap because of this invention.
