SUBIVIARINE BOAT.

Specication of Letters Patent.

Patetd'Nov.; 19, 1918i.

Application filed January 28, 1918. Serial N o. 214,192.

T 0 aZZwLom t may concern Be it known that I, FRANK SCHLEGEL- Minori, a citizenv of the United States, residing at Cleveland, in the county of Cuyahoga and State of Ohio, have invented certain new and useful Improvements in Submarine Boats, of which the following is a speciication.

This invention pertains to submarine boats, and the invention consists in the construction and combination ofparts for submersing and floating the boat, substantially` as shown and described and particularly pointed out in the claims.

In the accompanying drawings, Figure 1 is a side elevation of a boat having my invention installed therein. Fig. 2 is an enlarged longitudinal section of a portion of the boat and showing one of the planes in submersing position. Fig. 3 is a cross section on line 3 3, Fig. 1, and Fig. 4 is a plan view of a plane.

The invention as thus shown may be said to be an adaptation ot the principle of the plane commonly used in air machines to a` sub-mersible vessel, and by which the position of the vessel in the water in respect to the surface is wholly determined and the vessel is submerged or brought to the surface by the inclinations of the planes at its bottom, as will now be fully described.

Thus, b represents the boat, which may have any suitable outline or shape and be of any practical size, and the planes 2 for controlling the boat are supported beneath the bottom thereof relatively as shown. The said planes are, however, of peculiar and original pattern or style adapted especially to be employed in water and so shaped that they will most etfectually promote diving or submersing of the boat, as well as rising to the surface. To these ends the said planes or plates are constructed of suitably heavy sheet steel with their length lengthwise of the boat and are both tapered and flanged at their sides, the wider end being toward the front or bow of the boat and the flanges f thereon deepening gradually toward the rear and narrower end, and the entire width and length of the planes is such` as to give complete control ot the boat for all submersible purposes. Two such planes are shown herein, but if the boat were of relatively greater length at least one additional plane might be used, if not more.

The said planes are supported from the keel 4 of the boat by a pair of L-shaped hangers 5 pivoted oppositely on the keel by means of a pivot bolt 6 and rigidly fixed to the middle portion of each plane at their outer ends by rivets, and the pivot is of such, nature vthat the planes can be tilted thereon endwise to give them more or less dip at each end according as the boat is to be carried down or up in theV water.

Incident to this arrangement I provide what may be termed a keel extension lengthwise beneath the keel proper and which has a bottom portion 7 resembling a heavy bar in this instance and parallel to the keel, and walls or frame-work 8 built into the keel l at their top and into the bar 7 at their bottom and adapted to connect and strengthen said parts relatively and to serve as guides for the ends of the planes. The said planes, therefore, have notches or recesses in their ends formed in this instance between projections 10 side by side on said ends and loosely embracing the edges of said walls S and which confine the planes laterally and serve as guides therefor when they are tilted.

v Operation of the planes is from within the Vessel by means of cables c over sheaves l2 and idlers 13 and a controlling worm 14 about which the cable has several winds, and which has power vmeans at l5 to rotate the same and operate and control the position of the planes. The cable passes through upright tubes 16 at each side which are interposed between the said sheaves and idlers 12 and 13, and the cable has enlargements 17 thereon adapted to slide in said tubes and serve as cut-offs or closures therein to prevent the water from passing up through the tubes into the boat. The cable is engaged at its ends with the respective ends of the planes by eye staples 19 or their equivalent, and the operator has simply to control the power means 15, which may be an electric motor or other suitable engine or power medium which is geared or otherwise operatively connected with the worm 14. Assuming that the front of the boat is at the right in Fig. 2, the plane shown in said view has the extremity of dip to submerse the boat, but the two planes preferably have independent control.

The peculiar shape of the planes with their converging sides and gradually deepening anges is found to contribute materially to the forced descent of the vessel when submerging occurs, and the planes also planes pivotally supported from the keel beneath the same, means to tilt the planes and guides for the planes at the ends thereof.

2. A submarine boat having governing planes pivotally supported at their middle 'from beneath the keel and fieXible means connected with the ends of the planes adapted to control their working position.

3. In submarine boats, planes adapted to cause the boat to submerge having greater length than Width and provided with flanges at. their sides of gradually increasing depth toward the narrower ends.

4. In submarine boats, a series of planes having substantially flat bodies and flanged sides, the flanges thereof increasing in depth from end to end and curved inwardly in their deeper portion.

5. A submarine boat having pivoted planes beneath its bottom and cables to control the planes extending into the boat, tubes through which the cables pass and means on the cables in said tubes adapted to prevent the water from passing up through the tubes.

Signed at Cleveland in the county of Cuyahoga, and State of Ohio, this 7th day of January, 1918.

FRANK SCHLEGELMILCH.
