Реферат: 11,137. M³ller, O. M. May 27. Miners' safety lamps. - A locking-device, inaccessible to the miner, prevents the lamp from being lighted when open, or opened when lighted, and consists of a key a which at the same time as it locks the lamp, by fitting in one of. series of recesses in the collar d, also takes off the extinguisher n against the action of the spring g. The key a is held in this position by the prongs of a horseshoe steel spring h engaging notches u therein. This spring h is completely enclosed so that the key can only be released by pulling the prongs asunder by means of a powerful magnet. For gas or electric lamps, the key a instead of operating an extinguisher lever operates a gas cock or a contact-plug.
