Mortar-wagons

are designed for the transportation of siege-mortars and their beds, or of guns or large shot, and shells. A limber similar to the one for siege-gun carriages is used with it. The body consists of a platform of rails and transoms resting on an axle-tree. The stock is formed by prolonging the two middle-rails. The side-rails projecting to the rear form supports for the pivots of a windla -roller. This roller is used to load guns and mortars on the wagon by drawing them up the stock. A muzzle-bolster on the stock near the limber, and a breech-hurter near the hind part of the wagon, are provided and used when long pieces are transported on it. Mortars are usually carried mounted on their beds. The traveling-forge is a complete blacksmith’s establishment, which accompanies a battery for the purpose of making repairs and shoeing horses. It consists of a body, upon which is constructed the bellows-house, etc., and the limber, which supports the stock in transportation. The body is composed of two rails, a stock, and an axle-tree. The bellows-house is divided into the bellows-room and iron-room. Attached to the back of the house is the coal-box, and in front of it is the fireplace. From the upper and front part of the bellows an air-pipe proceeds in a downward direction to the air-box, which is placed behind the fireplace. The vise is permanently attached to the stock, and the anvil, when in use, is supported on a stone or log of wood, and when transported is carried on the hearth of the fireplace. The remaining tools are carried in the limber-chest. When in working order the point of the stock is supported by a prop. Nomenclature of the traveling-forge body: Lunette, prop, vise, stock, wheel-guard plates, stock-stirrup, fireplace, back of fireplace, air-back, wind-pipe, bellows, ribs, hinges, hook, fulcrum, hook and staple, roof of bellows-house, bows, studs, girders, end-boards, bottom-boards, side-rail, lock-chain hook, coal-box, lid or roof, handles, hinges, turnbuckle, and hasp. A new pattern of field-forge has been proposed by Col. Laidley, U. S. Ordnance Corps. The battery-wagon is employed to transport the tools and materials for repairs. Among the tools are those for carriage-makers, saddlers, armorers, and lab oratorians’ use, scythes and sickles for cutting forage, and spare implements for the service of the piece. The body of the battery-wagon is a large, rectangular box, covered with a roof of painted canvas; and to the back part is attached a rack for carrying forage. The bottom of the body is formed of one middle and two side-rails, resting on a stock and axle-tree, as in the traveling-forge. The tools and materials of the battery-wagon are carefully packed in the manner prescribed by the Ordnance Manual, in order that no difficulty may be experienced in finding a particular article when wanted. The smaller articles are carried in boxes properly lettered and numbered. The traveling-forge and battery-wagon are not confined to the service of field-batteries, but are used with siege and sea-coast carriages as occasion may require. Nomenclature of the battery-wagon body: Lunette, stock, wheel-guard plate, lock-chain, lock-chain bridle, lock-chain hook, studs, side-rails, upper rails, hinges, bows, cover-boards, cover-strap and turnbuckle, hasp, side-boards, stays, bottom-rails, bottom-boards, cro -bars, forage-rack, including chains, sides, and bars.
