[Illustration: FIG. 9.] When the shell is fired, the plunger is forced to the rear, driving the safety-plug into the shell. The small wires being free to let the plunger drive forward, hold it steadily with the rotation of the shell, and keep it from dropping forward on the descending arc of a high trajectory. On impact the plunger drives forward, and the little magazine is exploded by contact with the point. A Frankford Arsenal point percussion-fuze, small (model 1894), weight 2¼ oz., is now made for 1.65-inch ammunition. It is similar to the fuze for the 3.2-inch field-gun. DISMOUNTING. To dismount the mechanism: See page 4. To dismount the gun: Throw back the cap-squares and lift straight up at breech and muzzle. To dismount the wheels: Take out the linch-pins, lift the carriage at the axles and slip the wheels off. To dismount the axle: Slack back the clamp-screws about one turn; back the small keep-screws about four turns. Dismount the wheels; pull out the axle. To mount the parts, proceed in inverse order. LOADING-TOOLS AND INSTRUCTIONS. NOMENCLATURE.--Loading-press; loading-sleeve; common shell-plunger; canister-plunger; ejector; charge-measure; burster-measure; cartridge-funnel; shell-funnel; cleaning-brush; fuze-wrench. The loading-tools are supplied in sets, enclosed in an oak chest. They are not to be carried into the field, but should be set up in an appropriate laboratory room. For methods to be followed see instructions given for preparing ammunition for 3-inch gun, page 31, _et seq._ THE PACKING OUTFIT FOR 1.65-INCH GUN. This consists of: One pack-saddle, for carrying the gun and wheels of the carriage. One pack-saddle, for carrying the gun-carriage, the pole, the splinter-bar, the harness-sack (containing the harness and the pole-yoke), and the ammunition-pack. One pack-saddle, for carrying the four ammunition-boxes. One set of double harness. One pole and neck-yoke (the pole is hinged so that it can be folded for packing). One splinter-bar.
