Description
Dec. 2, 1930. c. F. SELZER SHIP STEERING DEVICE Filed July 50, 1928 FIG-Q1 WITNESSES ATTORNEY Patented 2, 1 930 CLARENCE F. SELZEE, 01 NORTH MILWAUKEE, WISCONSIN sm-s'rnmne nnvrcn Application filed July 80,
This invention relates to ship steering devices. I An object of the invention is to providemeans including displaceable wings arranged '6 at the side of a vessel for permitting the execution of rapid turning movements, especially in cases of emergency where danger of collision is imminent. Another object of the invention is. to pro 1 vide extensible wings of such character as to be capable of 'forming retarding means for decreasing the s ed of the vessel.
A further object ofthe invention is to so mount and displace the wings as to avoid the 15 accumulation of obstructing objects between the wings and the sides of the vessel.
A further object is to provide fluid-pressure-operated means for effecting the displacement of the wings.
The inventionfurther consists in the several features hereinafter set forth and more particularly defined by the annexed claims.
In the accompanying drawings,
Fig. 1 is a diagrammatic plan view of a vessel equipped with the steering means of this invention, one of the wings bein extended from the hull in a osition to e ect a turning movement of the ull;
Fig. 2 is a similar view showing the wing extended in such manner as to effect the clearance of obstructing objects between the wing and the hull;
Fig. 3 is a similar view showing the wing on its closing movement;
Fig. 4 is a similar view showing 'both the wings closed against the hull, and
F1g. 5 is a view showing both wings extended to form a means for reducing the speed of the vessel. In these drawings, the numeral designates a marine vessel, which may be either of the surface or submersible type. The vessel is provided with the usual rudder 11 at is also arranged at the stern in front of 'the rudder in the usual manner. A pair of wings 13 are arranged at opposite sides of the vessel,
preferably near the stern. Each wing is arranged to fit closely against the ,SldG of the Vessel and may, if desired, be disposed to he its stern, and a suitably driven propeller 12 1928. Serial a... 298,281.
flush with the sides of the vessel. Each wing 13 is supported near opposite ends on rods 14 and 15, which, in the present instance, are shown to be the piston rods of double-actin fluld-pressure-operated cylinders 16 and 1 65 respectively, arranged within the vessel in position to effect the projection and retraction of the rods and the wings carried thereby. The piston rods 14 and areconnected to pistons 18 arranged within the cylinders. Each forward rod 14 is provided with a pivv otal mounting 19 on the forward portion of the wing, and the rearwardrod 15 has a piv-' otal mounting 20 on the rearward portion of the wing. The forward pivotal mounting 19 is also arranged-to have a sliding or other suitable connection with the wing morder to avoid binding during the manipulation of the wing. The double-acting-cylinders 16 and 17 are so controlled that the piston rods 14 and 15 on opposite sides of the vessel may be selectively projected or retracted.
When the vessel is to be turned sharply in order to avoid a collision, or for other rea-' sons, it is only necessary-to project the for- 'ward rod 14 at that side of the vessel towards which the vessel is to turn, as seen in Fig. 1. The projection of the rod then causes the wing to assume the outboard divergent position seen in Fig. 1, which imposes a substantial drag at one side of-the vessel acting to sharply turn the vessel in the direction indicated by the arrow. -This turning movement may, of course, be influenced partially by the action of the rudderll, but the rudder action alone is not suflici'ent to permit the 1 making of a sharp turn. As, the wing is opening the projected forceof the water thereon acts to urge the wing outwardly but. the movement of the wing is restrained by suitably admitting fluid under pressure to the cylinder 16 to provide a cushioning me dium behind the piston 18.
After the turn has been executed the wing 13 is withdrawn in the sequence of operations indicated in Figs. 2, 3 and 4. First the rearward piston rod 15 is projected outwardly from the vessel to bring the wing 13 in sub stantially parallel'relation to the side of the vessel, thereby permitting any obstructing objects which have entered the space between the wing and the vessel to be discharged rearwardly from the wing. The forward p1s= ton rod 14 is then retracted, bringing the wing to the position shown in Fig. 3, in which the forward edge of the wing engages the side of the vessel. The rearward piston rod-15 is then retracted, thus bringing the wing close against the side of the vessel, as
seen in Fig. 4. In this manner either wing can be brought close against the side of the vessel since there will be no obstructing objects present to prevent complete closing.
This method of manipulating the win also When the wings are to be withdrawn they are simultaneously manipulated in the sequence of operations illustrated for one wing in Figs. 2, 3 and 4, and above described.
What I claim as new and desire to secure by Letters Patent is: j
1. The combination with a vessel, of a wing adapted to lie closely adjacent the side of the vessel, and a pair of projectable members disposed one behind the other at the side of the vessel and each having pivotal connections with said wing, the forward of said projectable members on its outward move-' ment from the side of the vessel swinging said wing outwardly about its rearward pivotal mounting to efi'ect a turning movement of the vessel, and the outward movement of said rearward projectable member efiecting a spaced disposition of said wing with respect to the side of the vessel to permit the passage of obstructing objects between the wing and the side of the vessel whereby to permit a close retraction of said wing adjacent the side of the vessel.
2. The combination with a vessel, of a wing disposed to lie closely adjacent the side of the vessel, and a pair of independently operable means having pivotal connections with opposite end portions of said wing for projecting said wing away from the side of the vessel, whereby to effect a turning movement of the vessel, and to effect a retraction of the wing in a manner preventing accumulation of foreign objects between the wing and the side of the vessel.
3. The combination with a yessel, of a wing adapted to lie closely adjacent the side of a .vessel, a pair of projectable members disposed at the side of the. vessel and having pivotal connections with o posite endportions of said wing, and a uid-pressure-operated means for inde endently reciprocating each of said pro ectable members to manipulate said wing.
In testimony whereof I aflix my signature.
