CLASS 4.—CHLORATE MIXTURE.

RACKAROCK.—Consisting of chlorate of potash and nitro-benzole.

CLASS 5.—FULMINATE.

FULMINATE.—The term “fulminate” means any chemical compound or mechanical mixture, whether included in the foregoing classes or not, which from its great susceptibility to detonation is suitable for employment in percussion-caps or any other appliances for developing detonation, or which, from its extreme sensibility to explosion, and from its great instability (that is to say, readiness to undergo decomposition from very slight exciting causes), is especially dangerous.

This class consists of two divisions.

Division 1 comprises such compounds as the fulminates of silver and of mercury, and preparations of these substances, such as are used in percussion-caps, and any preparation consisting of a mixture of a chlorate with phosphorus or certain descriptions of phosphorus compounds, with or without the addition of carbonaceous matter, and any preparation consisting of a mixture of a chlorate with sulphur, or with a sulphuret, with or without carbonaceous matter.

Division 2 comprises such substances as the chloride and the iodide of nitrogen, fulminating gold and silver, diazobenzol, and the nitrate of diazobenzol.

CAP-COMPOSITION.—Consisting of chlorate of potash and sulphide of antimony or sulphur, with or without fulminate of mercury and ground glass.

CLASS 6.—AMMUNITION.

Division 1.

PERCUSSION-CAPS.—A percussion-cap does not include a detonator.

RAILWAY FOG-SIGNALS.—Of such strength and construction, and containing an explosive in such quantity, that the explosion of one such railway fog-signal will not communicate the explosion to other like railway fog-signals.

SAFETY-CARTRIDGES.—Consisting of cartridges for small-arms, of which the case can be extracted from the small-arm after firing, and which are so closed as to prevent any explosion in one cartridge being communicated to other cartridges.

SAFETY-FUSE.—Consisting of a fuse for blasting which burns and does not explode, and which does not contain its own means of ignition, and which is of such strength and construction, and contains an explosive in such quantity, that the burning of such fuse will not communicate laterally with other like fuses.

TUBE SAFETY-FUSE.—Consisting of a pipe or tube of pewter, coated externally with tarred yarns, tapes, or other suitable covering, and containing gunpowder in the proportion of not more than 1½ oz. to every 24 ft. of fuse.

SAFETY FIRING-TUBES No. 1.—Consisting of a tube of metal or other suitable material, containing a percussion-cap and suitable mechanical appliances for firing the same.

Division 2.

(Not containing their own means of ignition.)

CARTRIDGES FOR SMALL-ARMS (which are not safety cartridges).

CARTRIDGES FOR CANNON-SHELLS, MINES, BLASTING, OR OTHER LIKE PURPOSES.

ABEL’S ELECTRIC TUBES.—Consisting of a case of wood or other suitable material, containing two insulated wires, the terminals of which are (a) imbedded in a charge not exceeding 2 grains of the priming composition No. 1, consisting of sulphide of copper, phosphide of copper, and chlorate of potash intimately mixed together; or (b) connected by a bridge of fine wire, composed of a platinum alloy, steel, or other suitable material, the said bridge being imbedded in a charge not exceeding 10 grains of the priming composition No. 2—viz., consisting of gunpowder and thoroughly purified gun-cotton: the case being fitted to a small cylindrical tube of quill, metal, or paper, or other suitable material, charged with gunpowder, and having a hollow up the centre of the same.

ABEL’S ELECTRIC FUSES.—Consisting of a case of wood or other suitable material, containing two insulated wires, the terminals of which are (a) imbedded in a charge not exceeding 2 grains of the priming composition No. 1 (hereinafter specified), or (b) connected by a bridge of fine wire, composed of a platinum alloy, steel, or other suitable material, the said bridge being imbedded in a charge not exceeding 10 grains of the priming composition No. 2 (hereinafter specified); the case being either (a) filled with a charge not exceeding 20 grains of gunpowder and closed at the end, or (b) empty and open at the end, or (c) fitted with a small hollow cylinder of copper, sheet-tin, or other material suitable for conversion into a detonator.

Priming Composition No. 1.—Consisting of sulphide of copper, phosphide of copper, and chlorate of potash intimately mixed together.

Priming Composition No. 2.—Consisting of gunpowder and thoroughly purified gun-cotton.

BRICKFORD’S PATENT VOLLEY-FIRERS—Consisting of a small cylinder of tin-plate, zinc, wood, cardboard, or other suitable material, into one end of which is placed a socket or block of wood or other suitable material, with a hole through the centre, and with a disc, wad, or cap, made of, containing, or saturated with a priming paste of mealed powder, at the base of the same, the said cylinder and socket or block being fitted with safety fuse or instantaneous fuse, or not so fitted.

BRAIN’S ELECTRIC FUSES.—Consisting of a case of wood or other suitable material, containing two insulated copper wires, the terminals of which are imbedded in a priming composition consisting of an intimate mixture of chlorate of potash, native sulphide of antimony, and sub-phosphide of copper.

ELECTRIC FUSES (SMITH’S PATENT).—Consisting of a plug of sulphur, containing two copper wires connected by a bridge of fine platinum or other suitable wire, surrounded by a priming charge of fulminate of mercury not exceeding one-fifth of a grain in any one fuse.

ELECTRIC FUSES.—Consisting of a case of metal, wood, paper, or other suitable material, containing two insulated wires connected by a fine wire of platinum or platinum alloy, and a charge of chlorate of potash and sulphide of antimony, not exceeding in all 5 grains, or, in lieu, purified gun-cotton not exceeding 10 grains.

HIGH-TENSION ELECTRIC FUSES.—Consisting of a case of wood or other suitable material, containing two insulated wires, the terminals of which are imbedded in a charge not exceeding 2 grains of a priming composition consisting of sulphide of copper, phosphide of copper, and chlorate of potash intimately mixed together, the case being filled with a charge not exceeding 20 grains of gunpowder, or carefully purified collodion cotton, and closed at the end.—(No. 1 Definition.)

HIGH-TENSION ELECTRIC FUSES.—Consisting of a plug of wood or other suitable material, containing two insulated copper wires, the terminals of which are imbedded in a priming composition consisting of an intimate mixture of chlorate of potassium, sulphide of antimony, silver precipitate, and plumbago.—(No. 2 Definition.)

LOW-TENSION ELECTRIC FUSES.—Consisting of a case of glass or other suitable material, containing two insulated wires, the terminals of which are connected by a bridge of fine wire composed of a platinum alloy.—(No. 1 Definition.)
