Abstract

296,277. Concordia Elektrizitats- Akt.-Ges., and Gosmann, W. March 19, 1928. Battery lamps.- In miners' lamps having a circular head mounted on a rectangular battery container, the rectangular body g of the container runs into a cylindrical flange g<1> adapted to receive an intermediate screw-threaded ring f to which the lamp head can be secured. The ring may be secured by bayonet rastenings j which are locked by the upward pressure due to an internal screw-threaded ring k which clamps the battery cover d in position.
