The nave-box (a) is made of aluminum-bronze. It fits over the axle-arm (c) and has groove for lubricant, as indicated. The nave (b) of malleable iron. The spokes, 16 in number (s), are made of oak or hickory. Fig. 56. The felloes, 8 in number, are made of oak or hickory. The tire is made of steel, ½ inch thick. The bolts, clips, linch-pins, and washers are made of metal. The large nut on outside of nave-box is splined to the box. The linch-washers have a stud which prevents their turning with the wheel. The inner extremities of the spokes are put together by a powerful radial pressure, which subjects them to a stress many times greater than they are likely to receive. To Replace a Box and that Portion of the Hub Attached.—Unscrew and remove front hub-band; take off hub-nuts, and drive out old box. Replace box, and screw on the front hub-band, replacing hub-nuts. To Replace a Spoke.—Remove tire and felloe on the injured spoke; take out only the bolt that passes through the injured spoke; saw off this spoke as close as possible to the hub and bore or dig out the spoke; drive in the duplicate spoke as far as possible, and arrange the tenon at the felloe so that the tire may press the spoke about one eighth of an inch farther into the hub, and after the tire is on put in the hub-bolt.

Bow-brake (2), Fig. 59, consisting of shoe-piece (a), bow-springs (4) (b), bow-spring nuts and bolts (4) (c), attachment-socket (d), and the attachment consisting of clevis (e), clevis-bolt and nut (f), locking-lever (g), locking-bolt and nut (h). Fig. 59. The attachment-socket has a rectangular longitudinal mortice in which the tang of the clevis is placed. This tang has a slot, the lower part of which ends in a hole having the same diameter as the locking-bolt. The locking-bolt has bearings on each side of the mortice, and the part in the slot has two opposite rectangular grooves. When the bolt is in the hole with these grooves perpendicular to the slot, the clevis is locked; but when turned until the bottoms of the cuts are in prolongation of the slot sides, the tang of the clevis can be drawn out until stopped by the other end of the slot. The Elevating Device (4), Fig. 60, consists of frame and double lazy-tongs. The Frame consists of (2) side-levers (c), pivot-bolt and separator (d), transom-bolt and nuts in rear, (2) eye-bolts, elevating-screw (f), cross-head elevating-screw nut, crank-handle (g). The Lazy-tongs consists of (4) long arms (a), (4) lever-arms (a), (4) short arms (a), upper assembling-bolt, (2) assembling-bolts, short, (2) assembling-bolts, long, central journal-bolt (e), lower journal-rod (b) and (2) bearing-boxes, (2) eye-washers (for strap k), and the necessary nuts and washers. The front end of the frame is attached to the carriage axle-plates, just in rear of the middle transom, by two eye-bolts which form the pivot. Fig. 60. The rear end is attached to the elevating-screw by the cross-head elevating-screw nut, which moves back and forth in the grooves in the side-levers in rear of the transom-bolt. The crank-handle on the elevating-screw is located just in front of the trail-box. The double lazy-tongs (of two cells, the upper twice the size of the lower) are enclosed in the frame which furnishes bearings, at about the middle of the side-levers, for the central journal-bolt. The lower journal-rod has fixed bearings in the two bearing-boxes which are bolted to the flasks of the carriage. The gun rests on the upper assembling-bolt, which has eye-washers for the breech-strap. Any motion of the elevating-screw handle raises or lowers the frame, and this, carrying with it the central journal-bolt, opens out or closes the lazy-tongs cells. The Double-screw Elevating Device, Fig. 60a, is used on 25 of the carriages for 3.6-inch guns. It consists of a hollow exterior screw (a) (having an exterior right-hand thread and an interior left-hand one) in which works an interior screw (c) to whose trunnioned head is attached the guide-strap (s), the arms of the strap being secured by nuts to the prolongations of the upper bolts that secure the middle transom. This insures rotation of the elevating device in a plane passing through the axis of the carriage. The bronze nut (b) in which a works is arranged on trunnions between the cheeks of the carriage, and has the hand-wheel (d) (or in some cases a large gear-wheel) so fixed to it that the latter can be rotated but has no motion of translation. A groove (e) is cut on the screw a, and a key on the hand-wheel fits this. Fig. 60a. Where the large gear-wheel is used motion is obtained by a small gear-wheel, axle, pinion, and hand-crank on the right of the trail. DESCRIPTION OF CARRIAGE FOR 3.2-INCH GUN.The carriage is made of steel. Its track, like that of the other vehicles, is 60 inches. The principal parts are the two flasks, connected by transoms, and the lunette; the two axle-plates, upper and lower; the axle-tree; the wheel-brakes; the wheels; the elevating apparatus; and the two seats. Each flask is formed by riveting together two plates with curved margins; and the trunnion-beds are reinforced by bars of steel, which are enclosed between the margins of the flask-plates and riveted to them. There are three front The shoulder-washers are octagonal in form; to each is fitted a collar containing a stout eye, to which the brakes are attached. These collars have projections that embrace the axle-plates above and below to prevent turning of the axle within the plates. Linch-washers have a stud to keep them from revolving with the wheel. Double-bow Spring-brakes, with a device for detaching them when necessary, are used. They are carried in a vertical position by means of the button on the lever and the groove on under side of axle-seat guard-rail. The spring-lever operates the locking-bolt in the end of the brake near the hook, so that the brake may be available in going up or down hill. Axle-seats are placed on either side of the carriage. Underneath the left seat a section of picket-rope is carried. The Elevating Device is of the lazy-tongs pattern, and is actuated by a handle on top of the flask. A leather strap is secured to the top part of the elevating device, and is used for strapping down the breech of the gun to avoid pounding. Wheel, Archibald, height 57¾ inches, weight 200 pounds. The Handspike, made of hickory, is sawn lengthwise into halves, and the wood thus removed replaced by 1/10-inch sheet iron, the whole riveted together and bound by iron bands. It is permanently attached to the flask, and when not in use is folded over on it and locked by the handspike-clasps. The Short Sponges and Rammers are carried between the cheeks, between the upper and lower front transoms; By means of the bronze hooks on the staff, one of which is movable, it is hooked to the right guard-rail when firing. The Axle-seats are attached at the shoulder-washers to the axle-plates and bolted to the flasks. The Long Sponge-staff is hinged near the middle, so that when folded the rammer-head is placed behind the sponge. It is carried on the left side of the carriage (the sponge-and rammer-heads under the axle-seat resting on the axle-plate), held by a toggle about midway of folded length. The Tool-box is placed between the flasks, and has ample space for all tools required, and for tube-pouches, priming-wire, and gunner's gimlet. By means of a hasp and turnbuckle the lid is fastened to the side of the transom. In rear of the tool-box is an open compartment in which the sponge-bucket may be carried when empty. A hole between the seats of sponge and rammer provides for carrying the bucket, when filled, by its toggle. Chin-and eye-bolts secure the cap-squares. Wheel-guards are bolted on either side of the trail. Weight of carriage and brakes, 1166 pounds. Weight of carriage complete, with equipment, 1197 pounds. Fig. 61.

THE CAISSON.Fig. 64.
Fig. 64a. NOMENCLATURE.
The limber of the caisson has already been described. The caisson, Fig. 64a, consists of one wrought-steel tubular axle and two Archibald wheels (57¾ in.), same as for limbers, the caisson-body, and connecting parts, viz.: The Middle rail (central part of body formed of two angle-irons) receives the lunette in front and spare wheel in rear, and is attached to the axle by an understrap, and to the side-rails by front and rear cross-bars, with connections stiffened by brackets, and the strength at axle increased by middle-rail braces. The Side-rails, which are attached to the axle by understraps and joined to the middle rail by the front and rear cross-bars. The Foot-board is fastened to the middle and side rails with brackets to incline the surface of the board. Floor-rods, passing through middle and side rails, between rear chest and rear cross-bar. Two Road-brakes complete, and attachments for implements and spare parts. The lever road-brake now supplied is similar to the ordinary wagon-brake, and so arranged that each side may be operated separately. The shoe is applied in rear of the wheel, and the brake-lever stands upright inside the wheels, opposite the front side of the rear ammunition-chest. The caisson body carries two ammunition-chests same as for limber. ON THE CAISSON CAN BE CARRIED:
STOWING OF CAISSON IMPLEMENTS.Long-handled Shovels.—The concave faces of the blades are toward and resting against the axle, under side, the shovel-points being passed into staple-straps in rear of the axle and the shovel handles afterward into catches on the front cross-bar, against which the ends of handles rest. The Pickaxes, which must be put on before the shovels, are carried beneath by fixtures attached to both middle and side-rails. The ends of the handles are brought together, the pointed halves of the blades overlapped, one in advance of the other (if the spare pole be on, this must be done above the pole); handle-ends are then passed into a broad strap of sheet metal depending from the middle rail, and at the same time the outer blade-ends into brackets or shelves on the side-rails. In this position the overlapping blades should be under a catch and immediately in front of a bracket or shelf on the middle rail, which is to support the picks, and to get them into which they should be pressed up against the spring and toward the axle until the spring falls behind them. This spring has, toward the axle, a long branch on which to place the hand when pressing up the spring to remove the picks. The Axes and Spades are carried between the chests. A The Canvas Buckets are carried in left compartment under limber foot-boards. The Lanterns.—Lanterns are carried in canvas bags hung across the spare-wheel axle-bolster. They hang below the floor-rods and do not swing. The picket-rope section, manoeuvring-handspike, and spare pole or spare wheel are carried as already indicated. Spare wheels, spare poles, and manoeuvring-handspikes are not considered part of the regular caisson equipment. In war-time it is proposed to carry on each spare caisson a spare wheel, on the left caisson of each platoon a spare pole, and on the right caisson of each platoon a spare handspike. In horse-artillery the front chest of each caisson-body should be removed to bring the gun-team and caisson-team loads to an equality and give space for forage. CAISSON, WEIGHTS AND EQUIPMENT.
COMBINED BATTERY-WAGON AND FORGE.Fig. 65.
This consists of one limber complete, same as gun-carriage limber except that the primer-and obturator-boxes are omitted, and the packing of the chest is adapted to securing the smith's tools and the forge instead of ammunition, and one metal body with Archibald wheels and tubular steel axle, same as for caisson except that the attachments for implements are omitted, while attachments are provided for anvil and sledge in front of the wooden body on the middle rail. The vise is mounted on the front end of the middle rail, and the attachment for the lunette-prop is under and continuous with the attachment for the sledge. The body (the entire top of which is covered with canvas) has three compartments. Two lids (one opening upward on either side and forming part of the top) open into one containing grindstone and stand-closets packed with stores and spare parts for the repair of the battery; and lids at the front end, opening into the other two, which contain chests of saddler's, carpenter's, and wheelwright's tools, all of which are so arranged that any one can be taken out without disturbing the others. A folding forage-rack in rear and a rail around the top provide space for carrying forage. The brake is the lever road-brake. Fig. 65a. NOMENCLATURE.

Left-hand compartment contains remaining tools and small stores, such as horseshoe-nails, small bolts, nuts, etc., to carry which two small canvas bags are provided. Limber-chest is locked, and key carried by blacksmith. The Coal is carried in the large canvas bag, capacity 3 bushels, on the foot-boards, lashed to the chest-handles by stout cords permanently attached to the bag, one of them being the cord by which the mouth of the bag is drawn together and secured. When empty, the bag is carried inside the chest. Further description regarding the stowing of the body part is unnecessary. FORGE AND BATTERY-WAGON, WEIGHTS AND EQUIPMENTS.
THE ARTILLERY-WAGON.Fig. 66. Weight complete, 1868 pounds. This wagon, on the canvas cover of which is painted its name and the designation of the battery, is made of white oak, and is for carrying the knapsacks, ammunition for small-arms, spare small-arms, and spare intrenching tools of the battery. It has the same track as the other artillery-carriages, and the axles are self-oiling, one filling lasting a month. The capacity of the interior is for 120 knapsacks, weighing about 3000 pounds. The rear wheels are 57¾ inches in diameter; the fore wheels are smaller, in order to turn under the body of the reach. The driver's seat is a lock-box of three compartments, the two end ones being for spare revolvers and revolver-cartridges. The middle compartment is for the following articles, viz.: 1 wheel-grease can and spatula; 1 self-oiling axle-grease syringe; 1 hand-hammer; 1 wrench. On the rear of the wagon is carried a 25-gallon water-keg, fitted with bronze screw-bung and a spigot. Under the body of the wagon and above the reach and rockers are carried the spare double (1) and single (2) trees, and the following intrenching-tools, viz.: 2 long-handled shovels, 2 spades, 2 pickaxes, 2 axes. To the foot-board is attached a dash-board lamp, which when not in use may be carried in the compartment under the driver's seat. A boot to protect the driver is also provided. The wagon has a double cover; the first, of water-proof canvas, covering the top only; the second, of cotton duck, extends down the sides and far enough in rear to lace at the ends. A stout canvas cover in rear of the driver's seat prevents the load from being thrown to the front. No special place is provided for the two canvas water-buckets, which should be carried where they can readily be gotten at. To fill the axle with oil remove the screw-washers and fill the spindles by means of the axle-grease syringe. THE WATER-CART.Nothing of this kind is supplied; but battery commanders can readily improvise one for field marches and encampments and find it exceedingly useful. Obtain two good substantial wheels and an axle; attach shafts; build a suitable framework thereon to sustain a large barrel, which should have a faucet in the rear end and an opening for filling it on top.

The width is changed at the top by using the different pads and connections. Each pad has its own connection, which forms the hinge at the top of the collar.
The collar is taken in at the bottom by shifting the bolt that holds the buckle in the side having the three holes. Each pad, connection, and collar-side has the number denoting its size stamped upon it. Any reference to the collar-side hereafter will mean collar-side and extension put together, which form the collar-side complete.
When it is necessary to put a No. 3 pad, the largest size, in the top of the collar, and adjust the bottom to the middle or smallest size, the collar-sides will have to be bent at the top under the eye enough to allow the collar to close easily at the bottom, and when the reverse is wanted the collar-sides can be straightened. In making these irregular changes be particular to get both sides of the collar the same length, so that it will close at the bottom. The sides can be easily twisted to make them come together evenly.
When it is necessary to bend the ends of the pads to make them fit closely to the collar-sides, use a wooden mallet. If a hammer is used, it will break the zinc on the galvanized parts.
THE ARTILLERY-WAGON HARNESS.
The same as regular artillery harness, omitting the saddles and substituting a back-strap, and replacing the curb-reins and coupling-reins by a set of regular driving-reins.
A four-in-hand whip is also used with the harness.
