Description

UNITED ETATEH PATEN T @FFTQE.
CHARLES E. GRANROSE, OF PHILADELPHIA, PENNSYLVANIA.
BOAT.-
Application filed November 11, 1907.
To all whom "it may concern:
ROSE, a citizen of the United States, residing at Philadelphia, in the county of Philadelphia and State of Pennsylvania, have in vented certain new and useful Improvements in Boats, of which the following. is a specification.
This invention relates to sail boats, the
object being, to provide a boat with a pair of sliding boards to each side of the keel, which. are so arranged that they can be moved up and down and. secured in their adjusted position, so that when the boat is on its starboard tack, the port board will be lowered, which will prevent the boat from -drifting laterally when on an uneven keel.
Another object of my invention is, to provide a boat with curved boards which are mounted in curved wells, whereby when lowered. and the boat is on an uneven keel the board will stand vertically.
Another object of my invention is, to provide very novel means for operating these boards, whereby they can be readily moved. up and down in their respective wells, as when the boat is ondi'fferent tacks it is of course understood, that when the port board is lowered the starboard board. will be raised.
These objects are obtained by the novel arrangement and construction of parts hereinafter fully described and shown, in the accompanying drawings, in which:
Figure 1, is a perspective view of sail boat showing the application of my improved boards. Fig. 2, is a transverse sectional view through the hull of the boat.
In the drawing, A indicates the hull of an ordinary sail boat, which is provided with the ordinary center board B, which works up and down in the well B for preventing the boat from sliding. The hull is formed with curved wells 0 and. D to each side of the well B and opposite the mast of the boat, in which are slidably mounted boards F and. G, which are curved. to correspond with the respective wells. The wells being curved in opposite directions as clearly shown in Fig. 2, and it will be seen when one of the boards is forced downwardly and the boat is on an uneven. keel, the board will.
Specification of Letters Patent.

Serial No. 401,555.
stand vertically, so as to form a greater resistant to the water, thereby preventing the boat from sliding laterally when tacking, it is of course understood that when the coat is on its starboard tack the port board will be lowered, and when on its port tack the starboard board will be lowered. By this arrangement the difficulties now existing of boats sliding when beating to the wind is overcome. To enable these boards to be readily operated, I provide the respective board with rods F and G which work up through slots formed in the top of the well and are provided with series of space open ings F G through which pins H and I are adapted to work for securing the boards up in the wells. The ends of the bars being provided with handles so that they can be readily grasped. from the deck.
From the foregoing description it will be seen that I have provided a boat with a pair of movable boards which are so arranged that they can be easily and quickly raised or lowered, so that there will be no time losti when the boat goes about on another tae c.
Having thus described my invention what I claim as new and desire to receive by Letters Patent is,
1. The boat provided with oppositely curved wells to each side of its keel, curved boards working in saidwells and bars connected to said boards for operating said boards.
2. A boat hull provided with oppositely curved wells to each side of its keel adjacent its bow, of curved boards slidably mounted in said wells, the curvature of said boards corresponding to said wells, bars connected to said boards provided with spaced openings, pins adapted to extend through said openings for securing said boards in said wells, and handles formed on the upper end of said bars for the purpose set forth.
In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.
