The carriage-body consists of two steel brackets forming stock and trail. They are reinforced by angle-steel and connected by transoms. The axle is stiffened by a reinforcing-plate to which is riveted the carriage-body. The elevating-gear consists of a forked lever, pivoted at its nearmost end, and traversed near the middle by the elevating-screw. The latter is supported by an inclined plane on the elevating-transom. The breech of the gun rests freely on the end of the elevating-lever, the preponderance being sufficient to insure stability. Recoil is checked by two rope-brakes, which are hooked to the trail-handles and passed around the felloes of the wheels. For the march one end of each brake is hooked to a trail-handle, the rope passed diagonally over the trail end and the free end secured to one of the hooks under the axle. The sponge and rod are secured by suitable attachments on the right side of the trail.
