My invention relates to under-water image transmitting apparatus, and it is a general object of this invention to provide a new and improved type of apparatus by which an operator at a land station, a surface or underwater ship may observe under-water scenes located at various depths and distances from the station or ship where the operator is positioned.

Another object of my invention is the provision of a mobile marine image observing unit capable of operation, on the surface or submerged, by propulsive means continuously. under the control of an operator located at a remote point.

An additional object of my invention is to provide a mobile unit with an illuminating or my producing element for projection on a scene and an image viewing and scene pickup element which may be directed to any desired point by means of horizontal and vertical deflecting mechanisms, forward and backward propulsive devices, with all movement and operations of the mobile unit controlled from a distant remote point by means of a flexible cable raised and lowered by a suitable winch, and the required operating switches, gauges, and other apparatus connected thereto, and combined therewith.

A primary object of my invention is to provide in efiect a mobile periscope or marine seeing device which I call a submarinescope which may be operated from a remote control station and which will transfer and depict the scene picked up to a screen positioned in a more or less distantly located surface ship, land station, or an underwater ship commonly known as a submarine.

An important object of my invention is to provide in efiect a mobile periscope or submarinescope by means of which a submarine, surface vessel or land station may discover the presence of and visually evaluate the military significance of other submarines, mines, nets, ships and other military devices without betraying the location of the remote control station which is receiving the information picked up by the mobile submarinescope.

A further object of my invention is to provide a mobile viewing unit, transmission system, remote control station and image screen which may be employed to detect, locate and explore sunken ships or other valuable objects which it is desired to salvage.

Another object of my invention is to supply a remote controlled mobile viewing unit capable of use in supervising, directing and controlling undersea salvage operations and undersea military 3 Claims. (01. 178-68) a monitoring device by which the scenes continuously picked up by the mobile viewing unit may be permanently recorded on photographic film or other recording mediums for subsequent stationary or moving picture reproduction.

Certain further improvements inrelated mechanisms and additional or auxiliary devices, attachments and coordinating apparatus which are considered as differing species relating to this invention and requiring division are being made the subject of separate applications soon to be filed.

Additional objects and advantages of my invention will be apparent from the following description considered in conjunction with the accompanying sheets of drawings, or from both as supplements of each other, wherein are set forth certain novel features of construction, combination and arrangement of parts.

In the accompanying sheets of drawings, forming a part of these specifications, and in which like numerals are employed to designate like parts:

Figure 8 is a front'view of the visible image screen and the control panel.

Referring now in detail to Figures 1, 2, 3, 4, 5, 6, 7, and 8, wherein for purposes of illustration are shown preferred embodiments of my invention, the numerals 9 indicates a wrecked ship resting on the bottom of the sea; Numeral H3 is a control ship riding on the surface of the sea. At a suitable place on the control ship is located winch mechanism l3, from which the control cable I2 connects to the mobile unit H, which is illuminating and picking up the image of the wrecked ship 9.

In the mobile unit H, as shown principally in Figure 2, I5 indicates the front section of the shell, in which are mounted the illuminating device, viewing mechanism and depth or pressure recorder and indicating compass. I6 represents the limits of the sight viewed by the pickup device, and I1 represents the beam impinging on the sight as emitted from the ray projecting device. I8 is a releasably sealed port for inserting and adjusting the illuminating device. I9 is a releasably sealed port through which ballast may be inserted in a ballast chamber. A clamp I4 for securing cable I2, is releasably attached to the middle section H5 of the mobile unit II. Sectionalized fins 20 are provided on both the middle section H5 and the rear section H6 of the mobile unit. To the rear end of section H3 is releasably secured a deflecting and propulsion mechanism mounting frame H1, to which the left and right horizontally deflecting rudder 2| is attached. The horizontally deflecting rudder is diverted to the left by an electromagnetic system 23 and 22 and is diverted to the right by the electromagnetic system 24 and 36. To shaft H8 rotatably suspended in mounting frame H1 is fastened the vertically deflecting rudder 25. The Vertically deflecting rudder 25 is diverted downward by the electromagnetic system 28 and 26 and is diverted upward by the electromagnetic system 21 and 26. Rotatably suspended in mounting frame H1 is the propeller 29.

Figure 3 representing the front view of the mobile unit II shows at 3| the lens of the imageviewing mechanism, at 32 the lens of the rayprojecting system, and at 30 is shown the exterior of the depth or pressure gauging mechanism.

The illuminating or ray-projecting system includes a filament 33 with the rays reinforced by reflector 34 and projected outwards through the lenses 32. An indicating compass 31 is secured in a floating mounting to a wall of the middle section H5. The middle section H5 is divided into several different compartments. Upper ballast chamber I is shown at I81 and lower ballast chamber 2 at I88. Separating these ballast chambers I and 2 is an equipment section which holds oscillators 49 and 41, primary amplifier 52, and the main amplifier 50. Cable H9 represents the Wires interconnecting the various pieces of equipment located in the mobile unit.

The propulsion motor 12 is contained in housing I86 of rear section I I6. Current for operation of the motor and propeller is supplied through collector ring III, brush H2, and ground return friction spring I20. The rotation of the motor 12 is transferred to propeller 29 by means of magnets 86 and 8| attached to propeller shaft 82, and electromagnets 18 and 19 attached to shaft of motor 12 and excited by current supplied through brush I I3 and collector ring I I4.

Winch mechanism I3 is supplied with a series of brushes I02 and collector rings I83 for the purpose of connecting the circuit wires to the cable I2 while permitting the cable l2 to be raised or lowered.

On the visible image screen and control panel Figure 8 are mounted the screen 55, horizontal deflecting switch 86, propeller control switch 16,

vertical deflecting switch 9 I, ray projecting switch 35, compass indicator 1|, cable winch control switch I00, and pressure-depth indicator 95.

My invention as schematically shown in the electromechanical diagram 5 consists principally of the combination of a number of elements; a remote control panel, a visible image depicting screen and a captive mobile ray-projecting and image pickup device. For purposes of illustration the remote control panel and visible image screen are depicted as located on a surface ship, while the ray projecting and image pickup device is depicted as a submersed mobile unit connected to the surface ship equipment by means of a flexible cable and winch. The various connecting and coordinating facilities for the principal elements are displayed so as to indicate their relative locations and functions in the combination as a whole. In the operative functioning of my invention the ray projection system consists of a source of radiant energy such as a light ray lamp 33 connected to ground 63 and through conductor 64 to remote control adjustable switch 35, thence by conductor I24 to power source 4|. The beam of radiant energy I1 is confined and directed by reflector 34 and lenses 32. Pressure depth recorder 30 is connected from ground 93 through conductor 94 to pressure depth indicator 95 and thence by wire 96 to power source 4|. In the viewing device such as an Iconoscope an appropriate cathode ray tube picks up and converts the scene into electrical signals. The beam or ight l6 of the picture passing through screen 49 is focused by lenses 3| forming an image on the mosaic 33 which is scanned by an electron beam I25 emanating from the electron gun 39 having horizontal deflector plates 43 and vertical deflector plates 44.

The electron beam I25 in traversing the image on mosaic 38 causes a flow of current or electrical potential varying in accordance with the illumination 0n mosaic 38 in the video circuit passing through signal plate I26 and collector I21. The variable video circuit is conducted by wires 53 and I28 to primary amplifier 52. The modulated circuit of the primary amplifier 52 is conducted to the main amplifier 50 and from thence through flexible cable I2 and winch I3 to cathode 51 of cathode gun I32 by wire I38 and to valve or grid I33 of cathode gun I32 by wire I3I. The modulated potential imposed on grid I33 varies the strength of electron stream 56 in accordance with the image on mosaic 38. This variable electron stream 58 impinging on electron sensitive screen 55 thereby creates a luminescence of screen 55 depicting the scene as viewed by mobile element II and picked up by mosaic 38.

The electron gun 39 is provided with horizontal deflector plates 43 having one plate connected to ground 45 and vertical deflector plates having one plate connected to ground 45. The other horizontal deflector plate 43 is connected to amplifying oscillator 41 and thence by conductor 60 to one of the horizontal plates 58 of electron gun 32 and the other vertical plate 44 is connected to vertical deflection oscillator 49 and thence by conductor 6| to one of the vertical plates 59 of electron gun 32. Oscillators 49 and 41 and amplifier 50 are supplied with power by means of conductors 5|.

A monitoring system for recording on photographic film or other medium the visible image projected on screen 55 is shown at I 2| operated by power conducted through wires I23 from power source 4| and controlled by switch I22.

In general use the mobile viewing unit or submarinescope II is directed and moved away from the control station located on ship III by the operative functioning of the motive mechanisms in the mobile unit I I and the gauges and switches located in the control panel 8 through the interconnecting wiring system and flexible cable I2 and Which mechanism I3 in such a manner that the desired scenes are depicted on screen 5 located in the control panel 8 as follows:

The mobile submarinescope II is placed in the water by paying out the flexible cable I2 from winch I3 controlled by switching mechanism I00. Subsequent to entrance into the water mobile unit I I is moved forward or backward by operation of the propulsion motor control switch mechanism I8. Movement of mobile unit II in the water to the right, in a straight line or to the left, in a horizontal plane is obtained by operation of the control switching mechanism 83. Movement of mobile unit I I in the water upwards, in a straight line or downwards, in a vertical plane is obtained by operation of the control switching mechanism 9|. As the mobile unit II travels in the water, the depth or pressure is indicated by recorder 30 and indicating gauges 95 and the relative direction is obtained from compass 31 and indicating gauge I I. Scenes or images at which the mobile unit I I is directed are illuminated or activated by the rays projected from the ray producing device 33 of a suitable strength as controlled by the switching mechanism 35. The scene thus illuminated or activated is picked up and transferred into electrical signals at the electron gun 39 and auxiliary equipment, then transferred by means of conductors in flexible cable I2 and other means, to receiving electron gun I32 and depicted on screen 55. If desired, a continuous pictorial record is obtained by the operation of the motion picture monitor mechanism controlled by switching mechanism I22.

It will be understood that while the form of my mobile remote controlled viewing device herein described and illustrated is to be considered as a preferred embodiment of my invention, I do not limit myself to the precise construction as described but reserve the right to resort to and substitute various modifications and changes in shape, size and arrangement of parts without departing from the spirit of my invention or the scope of my claims as described and indicated above and in the drawings and. the following claims.
