Lantern which extinguishes when subjected to impact or tilting

摘要

A lamp containing fuel (16) and a wick (20) dipping into it has the upper end of the wick protruding from the housing (12) through a vertical pipe (24). A device safeguarding against impact and tilting comprises a cage (28) attached to this pipe and the cage has a vertical stud (44) supporting a heavy ball (48). There is a spring (50) compressed by the bottom of the cage against the top wall (18) of the fuel container. The cage can slide vertically and the wick passes through it. If the ball is knocked off by an impact, etc, landing on inclined arms (54), the cage rises and the pipe slides out of the housing to extinguish the flame.
