Show I A Now Electrlo Fur Slcrial. A fog signnl hua been invented by Mr. , Norman Stanilaud, of Bath, England. The ' apparatus for carrying aad exploding thb cartridges is fixed on the locomotive aud ; la adapted to be worked by the compressed nir or vacuum of the brake reservoirs. Aa outer fixed cylinder has u smaller cylinder slidieg into it, this latter having a tube fixed diametrically across it. The compressed com-pressed air can only escape to the atmosphere atmos-phere through this cylinder and tube. The compressed air first forces aeurt'idgs from the mauuzico into the tube, ttus closing , egress of tho compressed air. The inner cyliuder is then forced along till the cart-I cart-I ridge In the tube is in a safe position for 1 flriug. In moving up the two needles have i been forced into the cartridge. An electrical contact wheel Is suspended i from the locomotive. When this cornea on ' a rail fixed for the purpose an electrical ; circuit is closed and a spark sent between j the two needles. The cartridge is exploded, ' allowing the compressed air to escape, aDd ! tho tube is pulled back by u spring, to re-i re-i pent the operation. The moving parts are ! bimple and the working is free from shocks, j Tliu electrical uppuratus consists of u battery bat-tery aud a small sparking coil carried on the engine. New York Telegram. |
