Richard Richards, Manchester. "Improvements in vessels and appliances for raising sunken ships, and other submerged bodies." This consists in fitting hollow columns to steam

vessels, extending from the main-deck to the keel, and there being open to the water. On the main-deck a pair of standards are placed, one on each side of each of the hollow columns, with a cross-head working in grooves in the standards, which forms a clamp for gripping a wire-rope or chain passing down the hollow column, and secured to the sunken ship. Beneath the cross-head a pair of powerful hydraulic presses are placed, which raise the cross-head and the weight secured to it a short distance each time, the rope or chain being clamped between decks, and the cross-head re-adjusted for another lift. Two vessels of similar construction are preferably used, that the chain passing beneath the sunken ship may be raised at both ends simultaneously.

3714. Richard Rose, Leadenhall Street, London. "Improvements in apparatus for saving life in the water, and for extinguishing fire on board ship." This refers to the construction of seats for passengers, and consists of a vessel constructed of metal in two parts, capable of being used as a seat, and which, when thrown overboard, from its buoyancy will support two or more persons. The seat resembles in shape a double egg cup, and is capable of being unscrewed in the middle, so that in the event of a fire occurring on board, the two vessels may be employed in carrying water. Each half of the seat is provided with a lid, and forms a receptacle for food, water, papers, &c., in case of wreck. When required only as a life-buoy, the lids are fastened down, and furnished only with endrails and central lines.

3751. Edward Gardner Colton, of the office of Wm. P. Thompson and Co., Patent Agents, 6, Lord Street, Liverpool. "Improvements in or appertaining to marine engine governors." (A communication in trust to him from abroad, by John A. Suedberg, of Washington, District of Columbia, U.S.A.) The object of this invention is to produce a simple and efficient mechanism for the purpose of automatically regulating the speed of a marine engine when the vessel is exposed to rough seas, in which the propeller is often raised partly or wholly out of the water. It consists of a pipe, fixed outside the vessel, open for the admission of water, and communicating on the inside with an air chamber. To a diaphragm, connected by a pipe to the air chamber, is

jointed a lever, pivotted to the stem of the balanced piston valve, in connection with a small intermediate steam cylinder. When the propeller is immersed, the air in the air chamber is considerably compressed by the water in the communication pipe, with a head nearly equal to the perpendicular distance from the pipe to the water-line at the stern-post, and as the air communicates with the diaphragm the latter will be expanded, thereby moving the lever jointed to it and valve to which the lever is pivotted, and admitting steam to the intermediate steam cylinder, which moving the cylinder with its connections, instead of the piston, in the same direction keeps the throttle valve open for the admission of steam to the main engine. As soon, however, as the propeller rises in the water, the head of water, and consequently the pressure, becomes gradually less; the diaphragm will be contracted, thereby moving the valve in the opposite direction, causing a similar movement in the cylinder and throttle valve, thus gradually shutting off steam to the main engine. A ball governor may be substituted for the diaphragm if it is desirable. to take the motion of the governor from the engine itself.

3776. David Kennedy, Liverpool. "Improvements in and relating to steering apparatus, worked by steam or other fluid, parts of which are applicable to other purposes where steam-engines are used." This consists first in placing on the hand-wheel shaft a cam, resembling a crown wheel, it being a disc with a series of small cams on the side near the circumference; secondly, in connecting the cylinders by piston-rods with a second shaft, having a worm that gears into the chain barrel, excentrics being placed on the shaft with the worm wheel, with rods jointed to the valve-rods, with springs and valve connections so arranged as to prevent the valve from over-running the engine. The chain barrel may also be connected by a clutch with the wheel-shaft, so as to work by hand when required.
