CARRIAGES, LIMBERS, CAISSONS, COMBINED BATTERY-WAGON AND FORGE, ARTILLERY-WAGON.

The carriage for this gun weighs 1300 pounds. The first 25 carriages were made with the double-screw elevating device, and the second 25 with the first form of lazy-tongs, and were intended for the 3.2-inch gun. They have been changed for 3.6-inch guns by cutting out the upper-front transom under the trunnion beds leaving only enough metal on each side to hold the eyebolts of the forked radial bar for the elevating device, and cap squares with eyebolts have been substituted for the old cap squares with chin and eyebolts. The double-screw elevating device on the 25 carriages now having them are retained; but all others will have a form of lazy-tongs, operated by bevel gears and a crank handle at the side, like that of the double screw; otherwise the carriage is similar to that of the 3.2-inch gun already described. The limber-chests will probably be fitted for 36 rounds of ammunition; which is the only difference between limbers, caissons, etc., used with 3.2-inch and 3.6-inch guns.
