With continued reference to FIG. 4, the propulsion devices 15 and 17 each includea hollow L-shaped gooseneck, generally designated 21. A hollow base arm 25 and a transversely extending hollow secondary arm 27 are carried in the gooseneck 21 and are geared together. The secondary arm 27 includes a transversely extending drive shaft-receiving bore 31 in its projecting extremity (FIG. 5) and a drive shaft assembly, generally designated 37, projects coaxially through the primary and secondary arms 25 and 27 and extends out the bore 31 to mount a propeller 39. Thus, the gooseneck 21 may be rotated to swivel the propeller 39 about a horizontal axis, the primary and secondary arms 25 and 27, respectively, rotated to pivot the propeller 39 about an axis extending perpendicular to the horizontal axis and the drive shaft 37 rotated to drive the propeller 39.

As best seen in FIG. 4, the goosenecks 21 include base portions 61 which extend laterally of the shell 13 and have perpendicular necks 63 which are formed with openings 59 in their ends. The inner ends of the base portions 61 are formed with external ring gears 65 which mesh with drive gears 67 driven by respective drive motors 69 (FIG. 12).
The base arms 25 are formed on their inner extremities with external ring gears 71 which are driven by drive gears 73 that are, in turn, driven by drive motors 75 (FIG, 8). The outer extremities of the base arms 25 are formed with bevel gears 79 which mesh with bevel gears 81 carried on the inner extremities of the transversely extending secondary arms 27. The outer extremities of the secondary arms 27 are formed with laterally projecting bosses 85, in the ends of which the drive shaft-receiving bores 31 are formed.
The drive shaft assemblies 37 include base shafts 91 having pinions 93 on their inner extremities which are driven by pinions 95 carried on the drive shafts of drive motors 97 (FIG. 9).

Received telescopically in the upper end of the joy stick coupling 155 is a joy stick 157 which is keyed against rotation by a key 159. A hollow handle 161, which is keyed against vertical movement by key 167, is received rotatably over the upper end of the joy stick 157 and has a push button 163 mounted in its upper end. A dead mans, or safety switch, 165 is coupled with the lower end of the push button 163 for discontinuing power to the control whenever the button 163 is not depressed.

The other sides of such motors are connected with the center wiper of the potentiometer 49 through power amplifier 197 by means of leads 181 and 183 such that the two motors 75 are connected in parallel. A conventional feedback system 199 detects the angular rotation of the secondary arm 27 and feds such information back into the potentiometer 49 to avoid overshoot and insure rapid assumption of the desired position.

The simplified circuitry shown includes a battery 193 connected across the end wipers of potentiometer 53 and resistance 203. The resistance 203 is center tapped to form a bridge circuit and is connected to adjacent terminals of the motors 69. The center wiper of potentiometer 53 is connected through power amplifier 197 to opposite sides of motors 69. A conventional feedback system 201 detects the angular motion of the gooseneck 21 and feeds such information back into the potentiometer 53 to avoid overshoot and insure rapid assumption of the desired gooseneck 21 position.
In operation, the control apparatus 45 will have all its components biased to their neutral position wherein the side propulsion devices 15' and 17 will be facing rearwardly as shown in FIGS. 1 and 2 and the end propulsion devices 18 and 19 will be facing upwardly as shown in FIG. l. When the vessel is to be maneuvered, the dead mans button 163 is depressed to close the switch 165 and provide power to bridge circuit which control the drive motors 97. The vessel may be caused to move directly forward by the operator grasping the handle 161 and sliding the slide bars 123 and 125 forward on the mounting bars and 117 to adjust the potentiometer 47 to its more positive position thus unbalancing the corresponding bridge and causing the propellers 39 on the side propulsion devices 15 and 17 to rotate in their forward direction to drive the vessel forward.
To cause the vessel to move sideways, the operator will move the handle 161 to the right or left, depending on the direction desired, to cause the slide plate 139 to likewise move to the right or left on the slide bars 123 and 125 thus adjusting the lateral adjustment potentiometer 49 and unbalancing the corresponding bridge. Such bridge unbalance causes the motor 75 to rotate the drive pinion 73 (FIG. 4) thus rotating the respective base arms 25 thereby causing the secondary arms 27 to rotate and reorienting the propellers 39 to face to the right or left, as desired. It will be clear that the amount of wiper movement in the potentiometer 49 will cause a proportionate amount of rotation of the arm 27 to provide a corresponding amount of swing for the propeller 39 and that the feedback signal through the loop 199 will cancel the command signal when the desired adjustment is attained. Without the analog computer, the operator must also move the handle 161 forward or rearward to adjust potentiometer 47 causing propellers 39 to rotate.
To cause the vessel to move vertically, the handle 161 is raised or lowered to cause the stick 157 to correspondingly raise or lower within the housing 155 thereby adjusting the potentiometer 55 to unbalance a corresponding bridge and drive the motors 99 of the end propulsion devices 18 and 19 to cause such devices to rotate their respective propellers 41 in a clockwise or counterclockwise direction as dictated by the initial movement of the stick 157 to propel the vessel upward or downward (FIG.
As best shown in FIG. 11, to cause the vessel to roll, the stick 157 is pivoted to the right or left to adjust the potentiometer 53 thereby providing a signal to cause goosenecks 21 of the propulsion devices 15 and 17 to assume the desired reciprocal orientation. Without the analog computer, the operator must move the handle 161 forward or rearward to adjust potentiometer 47 causing the respective propellers 39 to rotate thereby placing the vessel in the desired roll. Feedback loop 201 rebalances the bridge circuit providing a null signal to motor 69 thereby proportionately displacing the position of gooseneck 21 the desired amount. If gooseneck 21 of device moved upward, then gooseneck 21 of device 17 moved downward a proportional amount.
The vessel is caused to pitch or rotate about a transverse horizontal axis by pivoting the stick 157 forwardly or rearwardly to adjust the potentiometer 51 to provide the desired signal to cause one of the end propellers 41 on propulsion devices 18 and 19 to push upwardly and the other to push downwardly (FIG. 10).
The vessel is caused to yaw, or rotate about a vertical axis, by rotating the handle 161 on the stick 157 to adjust the potentiometer 57 thus providing an actuating signal to cause one of the side propellers 39 on propulsion devices 15 and 17 to push and the other to pull to accomplish the yaw maneuver desired (FIG. 9).
From the foregoing it will be clear that the propulsion devices of present invention provide means for precision movement in any direction of an underwater vessel. The control system enables the operator to conveniently orient the propulsion devices to accomplish maneuvers with comparatively great precision and, by employing the computer, such maneuvering may be accomplished blind and with greater accuracy and ease. Travel in any combination of directions can be accomplished by merely manipulating the joy stick apparatus to initiate the appropriate combination of command signals.
Various :modifications and changes may be made with regard to the foregoing detailed description without departing from the spirit of the invention.
