Abstract

726,302. Pyrotechnic devices. HJELLNES, K. Sept. 16, 1953, No. 25620/53. Class 9(2). A pyrotechnic device for simulating the noise of hand grenades and other ammunition comprises a charge 8 in a paper sleeve 9 placed within a protective casing of such dimensions that there is an annular gap 6 around the sleeve 9. The casing is made up of three coaxial tubes 1, 2, 3 fitting tightly together. These tubes may be of kraft paper coated with adhesive and spirally wound to the required thickness. The innermost tube 1 is turned over on to an end closure 4 through which extends a fuze 7 to which the sleeve 9 is tied, and the intermediate tube 2 is turned on to a closure 5. Above the closure 4, the fuze ends in a primer 12 of sulphur or other material ignitible by friction, the primer being protected by a short tube 13 turned on to a closure 14 and provided with a friction surface 15. The outermost tube 3 is extended beyond the tube 2 to form a hand hold. After assembly the device is waterproofed, e.g. by dipping in paraffin wax.
