Detonator Economiser Transport (London), Oct. 11, 1901, p. the recent general report of the Board of Trade on rail-way accidents of 1900 attention is directed to fog-signallingappliances. The cost of signalling in a fog of six hours dura-tion over nine miles of urban and suburban railway was shownto be in all £35 8s. The cost of the detonators alone was£16 10s. It is not surprising that the Detonator Economiser,a joint invention of two practical railway men, should be wel-comed by several leading railways. The invention is designed toavoid the waste of using two detonators to ensure one This practice is resorted to through fear that a single detonatormay be removed without explosion, by a skidded wheel. and Partridges device, while it places two detonatorson the rail, and insures the second detonator being held theresecurely, prevents the waste of the second if the first be essential feature of the machine is to put two detonatorson the rail, and to use the force of the explosion of the firstto withdraw the second from the rail before the wheel reachesit. In the figure a 1 and a 2 are two bearings for bar 6; c isthe first detonator, placed in the usual manner on the rail, and Vol. XL, No. II.
