DEFINITION

Classification: 362/157

(under the class definition) Subject matter comprising (1) a casing to support an energy source on or within the casing and a light source or a support for the light source powered by the energy source; or (2) a support to hold an energy source and a light source or a support for the light source powered by the energy source; or (3) a light modifier connected to a casing or support designed to support an energy source used to produce light wherein the modifier directs light from a light source powered by the energy source; or (4) a battery and a light source totally supported by the battery; or (5) subcombinations and elements of, and accessories limited in use to, an integral self energized lamp which produces illumination for general lighting not provided for elsewhere.

(1) Note. A reservoir for a source of energy may or may not be claimed in patents before 1920. The total disclosure of patents prior to 1920 including such a reservoir for a gas, liquid or solid burner if meeting the requirements of this subclass will allow the placement of a patent in this subclass.

(2) Note. A gas, liquid or solid energy source, capable of chemically uniting with the oxygen of the air to produce primarily light and heat secondarily, a burner for the gas, liquid or solid energy source and an optical modifier of light generated by the energy source in the burner will be placed here when the energy source is contained integrally with the structure having the burner and the light modifier.

(3) Note. Electric energy sources such as primary and secondary batteries and electric generators are here when the

source is integral with the light generator.
