DIVING con'rarviuvcn ADAPTED FOR near-sue DIVING.
Application filed July 7, i926, Serial No.
Diving bells which are attached to a cable or to a chain, and lowered from a steamer upon the bottom vof the sea are well known.v The range of action of diving bells of this I type is however very limited as they arecapable of working only directly underneath the l vessel from which they have been lowered so that the vessel must remain accurately above the pointat which the diving'bell is working,
this being of course very difficult. Another inconvenience is that the diving bells while being lowered are tossed about just as much as the vessel itself unless the latter is anchored from all sides, this being however not '15 possible in many cases.
It has been proposedto move. a sled-like contrivance, capable of holding a diver, over the sea-bottom from the vessel moving on the I 1 surface of the water. I Such an apparatus Q however could only operate in a very limited depth and at an enormous risk tot-he diver, since the vessel above could not stop quick enough vshould the sled strike against obstacles on the sea-bottom, such as a wreck, an
- anchor, rocks or the like which, on account of the limited range of sight under-water, would only be observedat the last moment.
Neither of the above mentioned contrivances enables the execution of diving expedition as neither areadapted for carrying compli cated tools and the like, nor'are they capable of carrying more than one man. I g
It has further been proposed to use an in dependent divin boat as accommodation for the divers. Such 'contrivance would present the inconvenience that it has to be of comparatively large size because it must contain a large engine-plant with a large accumulator plant for independent drive so that it could not be accommodated. on a comparatively small-size vessel. The diving boat would have to be propelled to the point of use by its own power so that, eventually, besides-the electric driving means, an internal combusti on. engine would become necessary whereby the size of the diving boat would be further increased. v
These disadvantages are obviated by the invention as, a submarine which, although constantly attached to the vessel on the surface of the water, has her own radiusof independent action and is capable of independent movement, and can be accommodated in a.
shaft of. the-main vessel and carried-to any point at which it has tobe used. 7 I

, According to this invention a submarine l is used which. is permanently attached to a main ship 3- by a strong cable 2 and carries ,as an engine only an electromotor for driving one or several propellers 4. The submarine has all the apparatus commonly used for a submarine, as horizontal rudders 5, 6, vertical rudders 7, diving tanks, air tanks, trim tanks, air compressors and the like. 1 Special arrangements are made to prevent the cable 2, which attaches the submarine to the main ship, from getting entangled with the propellers or interfering with the several rudders. QYVith this object in view propellerprotectors or rudder-protectors of known type are provided. 1 v
A small size storage battery serves for emergency lighting and for drivingthe propeller for a short time in case the current supplied through thecable 2 should be interrupted. 1 In the mainsliip 3a shaft 8 is provided whichhas preferably inclined side walls 9 lined with wooden ribs 10. The front wall 11 and they rear wall 12 of the shaft are downwardly and outwardly inclined, the rear wall at an exceptionally large angle as shown at 12 in Fig; 1, for reasons which will be eX- plainedhereinafter. i
. The main vessel is further equipped with a powerfulsteam winch, on the drum 13 of which the cable 2 is wound up. Thecable might further be wound only a few-times around the winch drum the rest of, the cable cable is used for supplying to the submarine electric current for driving the propellers, the
' pump and other tools, the cable comprising is a detail of a cable supporting a being stored .iniahspecial cable tank. This also telephone wires which provide constant.
cpmmunication possibilities with the main 5 up.
The cable is conducted over a guide pulley 14 arranged in or above the shaft 8. The crown is preferably attached to the submarine by means of lugs 16. For certain special cases it may be advisable to make the connecting point 17 between cable and crown adjustable, i. e. so that it can be shifted on the crown. The walls of the shaft are protected by strong frames :20 braced againstthe frames and other building elements of the vessel, and
strong reinforcen'ients are provided at the compartments in the usual manner by means of transverse bulk heads, lenses and 26 being arranged in the forward frame, the
tion of the submarine can always be accucable.

At the bow or at t e sides tools may be arranged which are adapted to be operated from inside the submarine. A manhole having a trap door 27 commonly used in diving boats serves as entrance. The measurements of the shaft 8 are chosen so that the upper portion of the submarine is above the water-line whenit is being transported by the main ship. 7
The contrivanoe operates asfollows The submarine is transported bythe main vessel in the shaft 8 to the place of destination. At this place the submarine is lowered by means of thecable 2 so that it iscapable of executin inde endent movements in the direction 0 the V eel in any corresponding direction, in order to locate for example first a wreck 28 resting on the bottom of the sea and then to carry out the necessary operations. V i
For carrying the weight of the cable buoys 29 may be attached to the cable when the Cable is being unwound, so that by their buoyancy they intercept a partof the weight of the These buoys will be hereinafter described.
The-submarine is provided with a circular compass which is connected by the cable to a compass on the main vessel so that the locarately determined on the main shi The diving of the submarine is acilitated by flooding certain compartments.

With this iving'contrivance depths can bereached whichfhave never been reached by diving apparatus and all sorts of expeditions can be carried'out, to a certain extent independent from the anchor age or position of the mainship.
In a special form of construction of the invention the cable 2, which connects the submarine with the main ship, is not constructed fromend' to end as holdingand lifting cable but only a shortportionof the cable 2, which portion isattachedto the'submarine, the remainder of the cable being at great comparatively thin and just strong enough to carry its own weight and that of the thick portion and to Withstand the oscillations which mi itoccurin the cable.
