KEEL FOR SUB'MARINE BOATS.

SPECIFICATION' forming part of Letters Patent No. 303,843, dated August 19, 1884.

Application filed Januarv S, 18S-l. (No model.)

To @ZZ whom it may concern:

Bc it known that I, WALTER Hmiironn, a citizen ol" the United States, and a resident of Baltimore, county of Baltimore, Stateof Maryland, have invented new and useful AIniprovements in .leels of Submarine Boats, of which the following is a full and exact deseri ption, reference being had to the accompanying drawings, making part of this specification.

illy invention relates to improvements in keels of submarine boats; and it consists in providing cylinders or air-tubes,water-tanks, a detachable keel, a propeller, a rudder, and a torpedo-box, all adapted to work together and to be operated and controlled by attendants within the boat, and the objects of my improvements are, first, to provide means for sinking the boat to any depth required; second, to raise the boat in the water to any height required; third, to sustain the boat at any point under water; fourth, to move the boatwhile under water to any point desired in order to examine or attack an obj eet below the water-line. l attain these objects by the mechanism illustrated in the accompanying drawings, inwhich Figure l. is a longitudinal section of my submarine boat. Fig. 2 is a cross-section. Figs. 3 and 4 are alternate methods ol' suspending the detachable keel. Fig. 5 is a duplex cock for introduei n g air into cylinders, water-tanks, and boat. Fig. l5 is a cut-off to cover perforations made to admit the lug of detachable keel when the keel is dropped.

Similarletters refer to similar parts throughout the several Views, in wliieh A is the hull or fra-me of the boat, and may be huilt of wood, iron, steel, or other suitable material, and may be built in any shape desired with perl'orations in keel to admit the lug Oi' the iron weights suspended.

B B are air tubes or cylinders suspended. by means of bracket-bars, hooks, ropes, or other suitable eontrivance through the length, breadth, or on the inside or outside of boat, and may he made of india-rubber, rubberlined cloth, canvas, or other suitable material, and are capable ol" inilation and discharge at will by attendants within the boat, and are provided with vents and valve-cock C C, so that the air from cylinders may he admitted into boat and used for purposes of respiration.

D D is a detachable iron keel, and may be constructed of one or more `parts provided with lugs,which pass through slots or perforations made in keel ol' boat, and are suspended by means of pins passing through slot in lugs, as shown in drawings, Fig. 8, a modilcation of which is shown in Fig. 4, in which H is a pin attached to the iron weight D, and is made to pass through a. slot in keel. I is a chain attached to the pin H and the ,hook-lever J, and may be detached instantly by striking the bar F in Fig. 3, or by tripping the hook-lever J in Fig. 4. E Eare the lugs of detachable keel, which pass through the slots or perforations made in the keel of boat, andare provided with slots in which the pins F F move to suspend the keel. G- G are the water-tanks provided withvalves to admit and discharge the water and hose-couplings to admit the air, and are used in combinatioirwith the air-tubes and detachable keel to raise and lower the boat in the water. 'll I .l are a combination of lever, pin, and chain to act as an alternate means of suspending the detachable keel.

K K are bracket-bars, made in any manner to hold in position the air tubes or cylinders.

L is an ordi nary union or T joint in combination with the valves m m m, to control the introduction of air from the air pump or iloat.

M is an ordinary hose, connecting the submarine boat with the air-pump.

Nis a torpedo-box, and may be used as a place from which to work adrill for the'purpose oi' boring holes into the bottom or side of a ship and introducing explosive material.

O is an air-pump, and may he of any kind required, and can be located on the shore or on board aboat or lloat, or it may be located in the submarine boat and receive its air from a valve-iloat attached to the boat.

'P P is the armor-plated shell used when the boat is employed as a torpedo-boat.

Q is the elongated slot in the lug of the detachable keel, in which the pin is inserted to suspend the detachable keel.

It R are `grated windows used pose of observation.

S is the propeller.

T and T are water-tight doors to torpedobox. T is opened to preparea Fish or other for the pur- IOC) suitable torpedo, and when all is in readiness T is closed and T is opened, and the torpedo; floats up into position, and when the boat has y moved to a safe distance is exploded.

U is the rudder which guides the boat.

V is an air-valve to allow the escape of air from cylinders or boat.

W is a cut-off or slide-valve,which is moved over the slot or perforation in the keel to prevent water from entering the boat when the detachable weights are dropped to allow the boat to rise to surface.

The operation of my invention is as follows:I rIlhc iron weights, which form the extra keel, being attached, the cylinders or air-tubes are partially inflated to balance the weight ofthe keel, and the boat is moved forward in the water by means of the propeller to the place where it is desired to sink it. rIhc valves connected with the water-tanks and the vents connected with the aircylinders are then opened, and as the water-tanks fill and the air escapes from the air-cylinders the boat sinks until the required depth is reached, when the valves and vents are closed and the cylinders or tubes are inflated until a state of buoyancy is attained, and the equipoisc of theboat is maintained by the inflation or discharge of the air-cylinders, and may be aided bythe introduction and expulsion ot' water in the tanks. The boat is now in a condition to move forward under water to any posit-ion desired by means of the propeller and rudder operated by persons within the boat.

As indicating the statcvol the art in respect to air-receptacles and means for Ventilating submarine and other vvessels, I am aware that cylindrical wrappers made ot strong and thin material and inflatedI with an air-pump have been used, and do not claim air cylinders broadly.V I am also aware that water-tanks have been used for the purpose of sinking or waterlogging vessels, and do not claim watercompartments broadly.

I am alsoA aware that air-pumps have been scribed.

used for the purpose of compressing air in airtight compartments, and for the purpose of expelling foul air, and do not claim an airpump broadly.

I am also aware that a detachable iron keel has been used in a torpedo-boat held by means of electro-magnets, and detached by breaking the circuit, and do not claim a detachable keel held in position by electro-magnets and released by breaking the circuit; but

\Vhat I do claim, and desire to secure by Letters Patent, :is-

l. In a submarine boat, a heavy keel attached to said boat by means of slotted -pins or lugs E, and retained in position by pins passing transversely through the slots in said pins E, substantially as and for the purpose set forth and described.

2. In a submarine boat, a heavy keel attached to said boat by means ofthe slotted pins E, passin g through suitable perforations in keel ofsaid boat, in combination with the bar F, having the dependent angles F, substantially as and fo11 the purpose set forth and described.

3. In a submarine boat, aheavy keel, l), attached to said boat by means oi" the pin H, chain I, and, lever J, substantially as and for the purpose set forth and described.

4t. In a submarine boat, a heavy keel being made in sections, each being separately detachable by means of the slotted pin E, and bar F, provided with the dependents F', substantially as and for the purpose set forth and described.

5. rIhe keel D, provided with the pin E, in combination with the cut-oli' valve W, substantially as and for the purpose set forth and de- In testimony whereof Ihave hereunto set my hand this 7th day of January, A. D. 1884.
