Abstract
A warning detonator for use on railway tracks or the like is disclosed. The detonator comprises a tube or cylinder (18) having disposed therein at spaced apart locations a length of elastomer (20) and a first explosive component (24, 25). A second explosive component (21) is located therebetween. The second explosive component (21) is also disposed within a cartridge (19) inside the cylinder (18). In use the cylinder (18) is affixed along a length of railway track in a manner whereby the wheel of a passing train progressively compresses the elastomer from its outer end so as to burst an end face (23) of the cartridge (19) and drive the second explosive component (21) into contact with the first explosive component (24, 25) to cause detonation thereof.
Claims8
A warning detonator for use on a railway track, said detonator comprising a cylinder having a first explosive component disposed therein at substantially the center thereof, lengths of compressible elastic means disposed at or adjacent the ends of the cylinder and a second explosive component located inside respective cartridges within the cylinder and disposed between each of said elastic means and the first component whereby in used said cylinder is fixed along a length of said railway track so that a wheel of a passing train causes detonation of said detonator by progressively compressing said elastic means at one of the ends of said cylinder thereby causing one of said cartridges between the compressed elastic means and said first explosive component to burst so that said second explosive component therein is released and driven either directly and/or by air pressure into contact with said first component.
