THE CARRIAGE. The distinctive feature of the carriage is the arrangement for oscillation, the lateral movement being regulated by a clamp, which compresses, or allows to expand, a metallic ring concentric with the pivot around which the gun moves. The lever for elevating or depressing, as well as giving the oscillation, is peculiar to this gun. THE LIMBER. The limber-chest is opened in rear by a lid, which falls down, and is held in place by jointed braces, thereby serving as a shelf. When down, it exposes a series of drawers six in number, and two recesses for implements. In these drawers the ammunition is carried in the original pasteboard packages. Each drawer has a capacity for 45 packages or 900 rounds, thus giving to each limber 5400 rounds. INSTRUCTIONS FOR DISMOUNTING. 1. Unscrew the cascable and raise the breech-cover. 2. Remove the locks. To do this, turn the crank until one of the lock-cam recoil-plates is uppermost; rotate the corresponding lock about the recoil-plate until it is vertical, and draw it out at front. The other lock may be removed in the same manner. 3. Remove the ejectors directly by their pins. 4. Remove the lock-cam, raising it vertically by means of its journal-boxes. 5. Turn out the feed-valve and valve-lever screws, and remove valve, valve-slide, lever, and lever-slide. 6. Drive out the safety-crank pin, and remove crank. 7.
