BOAT.

Specification of Letters Patent.

Patented Dec. 26, 1911.

Application filed August 19, 1911. Serial No. 645,000.

To all whom it may concern:

Be it known that I, JOHN MALY, a subject of the Emperor of Austria-Hungary, residing at Bronx, New York city, in the county of New York and State of New York, have invented certain new and useful Improvements in Boats, of which the following is a specification.

The present invention relates to boats or ships and has for its object to provide means whereby the capsizing of a boat or ship may be prevented.

To accomplish my object, I provide a device which is adjustably suspended from the boat or ship and is adapted to be sub-' merged in the water, so as to allow of changing the position of the center of gravity according as necessary, in order to maintain the boat or ship in balance.

My invention consists in the construction, combination and arrangement of parts as hereinafter specified and claimed.

To make my invention more clear, the same is illustrated in the accompanying drawing, in which similar reference numerals denote corresponding parts and in which- Figure 1 is a vertical section on line 11 of Fig. 2; Fig. 2 is a plan view of a boat equipped with my new device; Fig. 3 is a section on line 3-3 of Fig. 1; Fig. 4 is an enlarged cross section on line 4.4l of Fig. 1 and Fig. 5 is an enlarged cross section on line 55 of Fig. 1. g

In the drawings, which form a part of this specification, 1 denotes a boat or ship of ordinary construction and which may be either a row boat, sailing boat, motor boat, or the like. Suitably suspended from this boat in an adjustable manner is a weighted body 2 which is arranged below the keel portion of the boat or ship and is adapted to be submerged in the water.

In the present embodiment of my invention, the body 2 consists of a pivotally supported plate extending longitudinally of the boat, and capable of being swung around its longitudinal central axis. To this end, the plate has attached to it at its ends in the central longitudinal line, arms 4:, which project beyond the ends thereof. Pivotally connected to these arms are vertically movable members 5 arranged at the fore and rear ends of the boat and projecting upward through suitable guides 6, 7 secured to the boat. The connection of the vertically movable members 5 with the arms 4.- is accomplished by pins 8, or the like, which are rotatively borne in the said arms and through which the vertically movable members 5 are passed. These members 5 may consist of rods, or other suitable means and there may be suitable means, as set screws 9, or the like, for fixing the same in the adjusted position.

When not in use, the body 2 is adapted to occupy the horizontal position shown in Fig. 4:, in which case the vertically movable members 5 are lifted until the upper surface of the plate 2 is adjacent with the bottom or keel of the boat or ship. Suitable means may be provided, which tend to maintain the plate in horizontal position. In the present example, a spring 10 is shown, one end of which is secured to the plate and the other to one of the vertically movable members 5, said spring having the tendency to tilt the plate 2 into the horizontal'position.

In position of use or in vertical position, the plate 2 may be maintained by a suitable latch mechanism, as 11 (Figs. 1 and 3) or the like. This latch mechanism consists of a spring actuated horizontally movable bar arranged on the plate 2 and adapted to normally project into the range of one of the members 5 opposite thereto. When the plate 2 is tilted into vertical position, the bar will snap behind the said member 5 thereby looking the plate in vertical position. When it is desired to bring the plate into horizontal position, the latch must be first released from the member 5. To this end, the latch 11 is connected to one arm of a bell crank lever-'12 fulcrumed in the plate 2 and to the other arm of which is connected a rope 13, chain, or the like, which extends upward into the boat and may be manipulated from within the latter by hand, or in any other manner to bring about the release of the latch. The tilting of the plate from vertical into horizontal position will take place automatically owing to the tension of the spring 10. In order to tilt the plate from horizontal into vertical position, I provide a rope or chain 1 1, which I attach to the plate near one of its longitudinal edges and which likewise is extended into the boat to be manipulated from within the latter in any suitable manner.

As already stated, when there is no occasion for changing the position of the center of gravity of the boat, the plate may 00- cupy the horizontal position (Fig. 4) so as to allow of the boat being used in shallow waters. But when, owing to certain circumstances, as high seas, etc., there is danger of the boat capsizing, the center of gravity must be lowered. This is accomplished by first pulling the rope 14 and thereby tilting the plate into vertical position, in which it will automatically be locked by its latch 11 and thereupon lowering the upright plate to the extent necessary.

The raising and lowering of the plate may be accomplished by ropes, chains 15, or the like, attached to the fore and rear ends of the plate and extending upward into the boat. To facilitate this operation, a windlass 16 may be provided in the boat over which the two ropes are adapted to wind and unwind.

Having thus described my invention, and the manner of its operation, I do not wish to be understood as limiting myself to the particular construction thereof, since various modlfications may be made thereln by those skilled in the artwithout deviating from the principle of my invention.

What I claim and desire to secure by Letters Patent is:

The combination with a boat, of a device for changing the center of gravity thereof, embodying a plate arranged centrally below the bottom of the boat and adapted to be submerged in the water, rods vertically slidable in the ends of the boat and pivotally connected to the said plate, a spring between one of said rods and said plate tending to tilt the latter into horizontal position, a latch mechanism on said plate cooperating with one of said rods to normally hold the former in vertical or upright position, means operablefrom within the boat to raise and lower the said plate and means within the boat to operate the said latch so as to release the said plate. I I

In testimony whereof I affix my signature in presence of two witnesses.

JOHN MALY.
