Invented by Henry Berry, this light box overcame the dangers of using vitriol with the used of a system of pulleys and stoppers which firmly close the bottle of vitriol when the box is closed. When opened a measured amount of the flammable solution an be administered to the match head which in turn bursts into flames and is then used to light the lamp.
