Safety Lamp Patent Model

12-17-1867

This safety lamp is a patent model constructed by John Harding of Warrington, Lancaster, Great Britain that received patent number 72,196 on December 17, 1867. Harding’s claim in the patent application is the “employment, and use of a soft-metal or other rivet, or other compressible plug, as a fastening for safety-lamps, instead of locks, screws, or other mechanical contrivances now employed.” The locking device can be seen on the base of this Davy-style lamp.
