Model of steering apparatus. This consists of two cast-iron standards, with two traverse boxes at the top. These boxes are screwed on to a toothed rack, which has a pinion on the upright shaft to which the steering-wheel is affixed, so that when the steering-wheel is turned either way, motion is given to the rack, and thence communicated to the rudder by means of two connecting rods leading to the tiller, which is placed on the head of the rudder. The apparatus, or steering-machine, is detached altogether, and is placed on the under side of the deck beams of the ship, and is free from any obstruction. When the sea strikes the rudder it runs amidships; the great leverage that the helmsman has gives him a proper command.
Model of roasting-shears, capable of lifting a boiler of 20 tons weight, and shears on this principle may be constructed to raise any weight that may be required. They are also adapted to put masts into ships. The model is made on a half-inch scale. The machinery is under cover, to protect it from corrosion, and to keep it in proper order. The middle storey is intended as a warehouse or loft for fitting up the rigging of larger vessels.
