Abstract

4196. Niditch, I. Feb. 18. Pyrotechnics. - Relates to railway-signal f u s e s containing a charge 2 of the mixture of potassium perchlorate and sulphur described in Specification 14,396/10 and a chlorate-of-potash igniting-patch 5, and consists in the interposition between the perchlorate mixture and chlorate igniter of a sulphurless composition 4 occupying about one to two inches of the front end of the fibre casing. The sulphurless composition contains 22 p a r t s of potassium chlorate, 60 parts of strontium or other nitrate, 8 parts of shellac, 2 parts of sulphide of antimony, 6 parts of greased sawdust, and 1 part of charcoal. It is separated from the perchlorate mixture by a layer 7 of a mixture of 24 parts of potassium perchlorate, 60 parts of sodium nitrate, 8 parts of shellac 2 parts of sulphide of antimony, and 6 parts of greased sawdust, and charcoal (1 part). These compositions are held together by a wooden peg 6 which has been boiled in a solution of 70 parts of lead nitrate and 60 parts of saltpetre.
