' "40mins. (o1.114 147) vide an improved construction of navigation control mechanism by which steering oflarge vessels, submarine boats, andaircraft may be facilitated.

Another object of my invention to provide a method of constructing a vessel having means associated with compartments in the vessel for displacing the fluid medium at positions along the vessel for facilitating thenavigation of the vessel.

A further object of my invention is to provide an arrangement of maneuvering .apparatus for vessels by which added driving power and extra speedmay be obtained by the .use of auxiliary the specification hereinafter following by referpropulsion means normally housed in streamline arrangement in compartments along the vessel.

Still another object of my invention is to provide an arrangement of maneuvering apparatus for vessels in which propellers are disposed in compartments along the vessel in the bow, sides, in the StCI'IIyOI in the bottom of the hull with streamlinedoors arranged to open or close-the compartments for the admission or discharge of the fluid medium through which the vessel is propelled- Other and further objects of my inventionreside in the arrangement of auxiliary propulsion mechanism for ships as set forth. more fullyin ence tthe accompanyingdrawin in which:

along the vessel for facilitating the navigation of I provide means auxiliary to=the main propulsion means of the vessel for providing additional driving power for the vessel for facilitating maneuvering of the vessel. I provide compartments below the waterline in the bow or stern of the vesselor along the vessel. Propulsion means are provided within, the compartments. Streamline doorsareprovided to open and close portions of the compartments for allowing ingress and egress of thewater through which. the vessel is propelled. 1 The streamline doors may be constructed from armor plate for aiTording maximum protection tot-he propulsion means. The propulsion means may be suitably oriented within the compartments in order to impart maximum effectiveness to the propulsion means. the propulsion means through electric motors or through suitable .transmission mechanism within the vessel. p

- In Figsland 2, I have shown methods of arranging the auxiliary propellers in separate commay be opened or closed by remote control, as

hereinbefore. explained in connection with the sliding doors on the hollow rudder. The compartments I04. and H15 are watertight and may be selectively employed in the maneuvering of the-vessel by the selective operation of the auxil- Propellers I06 and I? are operated by suitable drives I08 and H19, controlled from the control position aboard the vessel. I may locate these compartments in spaced positions at the bow, in the sides, in the stern or in thebottom of the hull of the vessel.

The compartments may be demountably connected to the prow of the Vessel as represented in Figs. 3 and 4.. I have indicated the lower portion of the hull at .l. The compartment 96 is watertight and has a substantially Wedge-like inher bulkhead which cuts the water as it comes from the auxiliarypropellers and throws it to the sides. The bulkhead however may extend laterally of the vessel or be provided with some other convenient shape. -I-- provide a'pair of streamline 'door closures 98 and 99 at the starboard side ofcompartment ilfi, I mount one or more auxiliary all propellers as represented at I02 and drive the propellers in a manner similar to a method of drive hertofore explained, such as through motors I03, or' by direct mechanical means. A single door may be provided at each side of the compartment, if desired. Various components of maneuvering forces may be obtained by coordinating the drive of the auxiliary propellers in different parts of the vessel.

The maneuvering propeller may be located in various positions ith respect to the hull of the vessel. For examples illustrated in Figs. 5 and 6, the propeller mechanism as heretofore described, may be housed in the hollow rudder 9 with respect to the hull of the vessel I, and coordinated for operation with respect to the main propeller 3 and, in addition, other maneuvering propellers may be provided. In order to illustrate the several embodiments of my invention I have illustrated in Figs. 5 and 6, an auxiliary propeller compartment in the skeg, as shown at 81 in Fig. 5, in which auxiliary propeller 88 is housed. To further facilitate the maneuverability of the vessel, I may provide a compartment 89 in the stern of the vessel in whichla pair of auxiliary propellers 90 and 91' are symmetrically arranged. Moreover, a rudder may be provided forward of the vessel, as indicated at 92. For additional control of the vessel, a compartment may be provided in the prow of the vessel, as indicated-at 94, in which auxiliary propeller 95 is located. It will be understood that separate controls extend from the several auxiliary propellers to the control position aboard the vessel and the operation coordinated'so that the maneuvering of a vessel of large size, is greatly simplified. A vessel of large size, of the order of 37,000 tons, drivenby 200,000 horse power engines may be maneuvered quickly and within a smaller area to change the course of the vessel, thus increasing the safety of life and property.

I may arrange the auxiliary propulsion means in compartments in spaced positions along the vessel as illustrated in Figs. 'land 8. In this arrangement, the hull of the vessel I is provided with port and starboard compartments l0 and -H within which the separate propulsion means -l2 and'ld are'located. Separate driving means for the propulsion means l2 and I4 may be provided as indicatedat i5 and IE or the propulsion means may be driven from a position within the vessel. vide a forward streamline door H and a rear streamline door 88 which may be opened and 'closed through suitable remote control mechanism from a control position 'within the vessel. In thestarboard compartment H, I provide a forward streamline door I9 and a rear stream- .linedoor Zilwhich may be selectively opened or closed in order to facilitate maneuvering and propulsion of the'vessel. Other methods of loeating these separate compartments in spaced positions may be employed, for example, in the sides of the hull similar to the arrangements in the, bow and stern illustrated in Figs. 1 and. 2. Suitable orientation means may be provided for effectively directing the propulsion means in a suitable position for the proper maneuvering of the vessel.

This application is a division of my copending application SerialNo. 105,112, filed October In the port compartment I0, I pro- 10, 1936, for Safety mechanism for improving the dirigibility of ships, submarines and aircraft.
