RUDDEB FOB SHIPS.

Application file-d Iune 15, 1925. Serial No. 37,259.

This invention relates to steering means for ships, the general object of the invention be ing to make the rudder in the form of a vertically arranged roller so that when rotated, it will so act upon the water as to cause the ship to turn in the desired direction accorc ing to the direction of rotation of the roller.

Another object of the invention is to provide means for turning the rudder at difierent speeds so as to control the arc in which the vessel is turned.

lVith this invention, a ship can be backed or reversed without interference on the part of the rudder and a rudder can be placed at the bow of the boat as well as the stern, which will increase the steering efiect.

This invention also consists in certain other features of construction and in the combination and arrangement of the several parts, to be hereinafter fully described, illustrated in the accompanying drawings and specifically pointed out in the appended claim.

In describing my invention inv detail, reference will be had to the accompanying drawings wherein like characters denote like or corresponding parts throughout the several views, and in which I Figure 1 is a. view of a ship provided with a rudder at each end thereof in accordance with this invention.

Figures 2 and 3 are diagrammatic views showing how the rudder acts 011 the current of water passing the same.

Figures l, 5 and 6 are diagrannnatic plan views showing how the improved rudder acts to steer a vessel.

Figure 7 is a similar view but showing a vessel equipped with two rudders at its stern.

Figure 8 is a sectional view of the means for driving one of the rudders.

Figure 9 is a similar View showing the means for driving another rudder.

Figure 10 is aview of the controlling means.

Figure 11 is a view of the motor generator.

Figure 12 is a diagrammatic View of the circuits.

Figure 13 is a diagrammatic view oi the controller arrangement.

Figure 14 is a. view of the steering apparatus which includes the regulator and the controller.

As shown in these drawings, the rudder 1. is made in the form of a cylinder or hollow roller which is vertically arranged and is socured to a vertical shaft 2 which is suitably j ournaled in the hull ofthe ship. Figure 1 shows a rudder at each end of the hull, thoughbut one rudder can be used, as shown in Figure l, or two rudders can be used at the stern of the hull, as shown in Figure 7. A motor 3 has its shaft connected with the upper end of the shaft- 2, the motor being supported by the supporting frame 4 which is arranged in the hull of the ship.

lVhen the ship is to be turned, current is supplied to the motor so as to rotate the rudder and this rotary movement of the rudder will create a current a which will move with the rudder, as shown in Figure 2, so that the current Z) shown bythe straight arrows at the top of Figure 2 will strike the current a and thus be deflected, as shown in Figure 3. The current at the point A will have its velocity increased, while that at B will have its velocity reduced so that but little pressure will be at the point A, while great pressure will be at point B. Thus the rudder will be forced in the direction of the arrow P, Figure 8, which will cause the ship to turn. Thus it is only necessary to rotate the roller in the proper direction to cause the ship to be turned. Figure 4: shows a ship provided with a single rudder at its stern and rotat ing in a direction to cause the ship to turn to starboard. Figure 5 shows a ship provided with a rudder at each end with the rudders moving in a direction to cause the ship to turn to starboard. Figure 6 shows a ship provided with a-rudder at each end and with both rudders rotating in the same direction so that the ship will move sidewise to the right. Fig ure 7 shows a ship provided with a pair of rudders at stern, one on each side of the propeller.

Some of the advantages of this inventirm are as follows Even at the low velocity of the ship, a strong steering power can easily be created by increasing the number of rotations.

The current of the water does not institute any reactionary eiiect to the rotation of the cylinder. f v

The rudder offers only a small surface to the waves and thus the danger of damage to the rudder in a storm or heavy sea is m1mmixed.

By reversed action of the ship, (when the ship sails backward), the rudder acts just as reliably and effectively, as when running ahead. p

If a second rudder is added, the steering effect will be naturally doubled and the ship possesses with this a reserve rudder whose interference with the motion of the ship is entirely negligible.

These two rudders will enable a ship to change its sailing direction transversely, without the ships body itself being turned in a transverse direction.

V The attaching of two cylinders at the sides of the screw (one cylinder at each side of the screw) is constructively easy and adds to the hydro-dynamic power.

By regulating the number of rotations of the rudder, the turning movement of the vessel can be controlled and while any desired means can be used to rotate the rudder, at

different speeds, I prefer to use an electric motor for rotating each rudder and the means shown in the drawings for supplying current to the same. These means comprise a motor and generator 6 which are connected by the conductors 7 with the currentsupply of the ship, a switch 8 controlling the connection. A rheostat or controller 9 controls the flow of the current to the motor generator. Conductors 1O connect the generator with the 1notors 3 of the rudders and the controller 11 and the regulator 12 are located in this circuit. These

members

11 and 12 are actuated from the steering wheel 18 through the gearing 14: and the gearing 15 so that they, operate in unison and these parts are so arranged that starting from zero, in either direction, the voltage is gradually increased as the steering wheel is moved so that when the rudder is thrown into operation, it will gradually pick up speed and according to the amount of movement of the steering wheel. Thus the ship. can be turned on a long are or a short one, as desired. Indicating means, shown generally at 16, are arranged in the circuits and are placed adjacent the steering wheel, as shown in Figure 10.

What I claim is 2- In combination with a ship, supper" frame therein arranged adjacent one end (i the ship, a vertically arranged motor supported by the frame with its shaft extending downwardly, a vertically arranged shaft passing through the lower part of the ship and in alignmentwith the shaft of the motor, means for connecting the upper end of said shaft with the motor shaft, a vertically arranged roller or cylinder attached to that part of the shaftprojecting from the ship and means for supplying current to the motorto rotate the'roller or cylinder to steer the ship.

In testimony whereof I affix my signature.
