TORPEDO AND OTHER SUBMARINE APIEARATUS.

Specification of Letters Patent.

Patented Apr. 2'7, 1915.

Application filed February 11, 1998. Serial No. 415,309.

have invented new and useful Improvements in Torpedoes and other Submarine Apparatus, of which the following is a specification.

This invention relates to improvements 1n torpedoes and similar submarine apparatus, such as mines, mining torpedoes, submarine boats, and the like.

The main object of the invention is-to provide a torpedo adapted to automatically steer, without any control, toward the ob ect to be destroyed, and to change its course according to the movement of the said ob ect.

A torpedo constructed according to thls invention is especially adapted to detect submarine boats or other hostile vessels and to i automatically steer toward the same, whatever be the original course of the torpedo. In torpedoes of the kind described in my earlier patent application Serial No. 400215, filed November 1, 1907, (patented March 22, 1910, No. 952,451,) special arrangements may be provided for causing the torpedo, after the propulsion of the same has ceased and it has taken up a vertical position, at a predetermined depth of submersion, to agaln start, as soon as a vessel enters 1ts sphere of action, and steer for the vessel to destroy t. In mining torpedoes having a mooring device, special arrangements may be provided for automatically disengaging the moored torpedo, as soon as a vessel enters 1ts sphere of action, so as to enablethe torpedo to start and steer for the vessel. Finally, a torpedo having devices according to this invention may be provided with special devices for automatically exploding it, in case it should pass the vessel without hitting it, the actlon being thereby essentially the same as if the exploding Was performed by percusslon.

In the following all the destroying means hereinbefore referred to are comprisedunder the common name torpedoes. Certain kinds of torpedoes are'provided with means for maintaining them at a certain predetermined depth of submersion after they have ceased moving, in order that they may act for some time as submarine mines, either of the subfloating (unanchored) type, or as anchored mines, if the torpedo is provided w1t h a mooring device adapted to be thrown nto action, when the torpedo ceases moving.

' invention, on the contrary,

Torpedoes of these kinds are hereinafter called mining torpedoes,

The invention consists, chiefly, in so placmg, on the torpedo, suitably atits fore end, a number of microphones, telephone receivers, or other receivers sensible to vibrations of the water, such as vibration of sound, or the-like, that the said receivers are adapted to be actuated by vibrations issumg from the object to be destroyed, each receiver being connected, by suitable apparatus, to one or more of the devices (steering, propulsion, exploding or other devices) of the torpedo in such a manner that the said device or devices will be actuated, as soon as the receiver is made active.

It has been proposed to steer torpedoes at a distance by means of the generation and transmission of sound waves, but these waves were generated at and transmitted from a controlling station at the launchingplace. Such method suffers from the disadvantage that the torpedo cannot be seen from the controlling station when it has traveled over a certain distance-therefrom, which makes it impossible to steer the torpedo at longer distances toward the object to be destroyed. The nearer the torpedo approaches the object to be destroyed, the more diflicult is the steering, and beyond a certain range from the controlling station the steering becomes quite impossible. According to the present the steering will become more and more infallible, the nearer the torpedo approaches its mark.

For automatically steering the torpedo,

each receiver may, suitably, be included in an electric circuit or electric circuits, connected, by suitable apparatus, to one or more rudders or other steering devices in such a manner that the said device or devices will be actuated in a certain direction,

as soon as the circuit is made active by variations in the resistance produced by the receiver. To this end the one winding of a transformer may, suitably, be included in the said circuit or circuits, the other winding of said transformer being included in a circuit containing one or more electroinagnets serving to operate the controlling means, such as the distributing cock of a servomotor, or an air pressure cylinder whose piston is connected, in any suitable manner, to the said rudder, but, obviously, other arrangements may be employed, and

the invention is, therefore, not limited to any particular arrangement for actuating the rudder or rudders. torpedo suitably four receivers may be employed,-said receivers being arranged about the geometrical axis of the torpedo, at an interdistance of about 90. The receivers situated in a central longitudinal plane diametrically opposite each other form together one pair of receivers operating the .ward the object emitting the waves of sound. The number and arrangement of the receivers may, obviously, be varied, but

in the ordinary torpedo type having one or more rudders for steering horizontally and one or more rudders for steering vertically the aforesaid arrangement of the receivers is preferred. The receivers operating a certain rudder should, obviously, be situated in a plane extending at right angles to the center of motion of the said rudder.

Although I prefer the described arrangement, the number of receivers might, obvi-' ously, be diminished inasmuch as two receivers situated in a horizontal plane for steering the torpedo horizontally may suffice, if the torpedo is caused, by known arrangements, to move at a predetermined depth beneath the water surface, but in such casethe torpedo can only be used as an offensive means against ordinary war vessels and thus loses its important feature as an offensive means against submarine boats, which are able to move at difl'erent depths.

In torpedoes of the kind-described in my earlier patent application (Patent 952,451) hereinbefore referred to the receivers may I? be employed not only for steering but also for starting the engine, when a vessel entersthe sphere of action of any of the receivers (supposing the torpedo to be at rest). This can be performed in several Ways, for instance by relays sgrving to close one or more circuits through-the starting arrangement of the engine (in the case of an internal combustion engine through the igniting device and, suitably, through one or more electromagnets operating valves for supplying air and fuel). In mining torpedoes provided with a mooring device the receivers may, further, be employed -for disengaging;-

the torpedo from the mooring, as soon as any of the receivers is actuated by sufliciently strong waves of sound, or the like. Also this is, suitably, performed by an elec- For steering thetromagnet, which, when supplied with current, attracts an armature serving as a releasing device. For starting the engine and disengaging the torpedo from the mooring special receivers for waves of sound, or the like, maybe employed, if desired. The exploding of the torpedo, in case it should pass the vessel toward which it moves, may, suitably, be performed by a rearwardly directed receiver placed inthe rear part of the torpedo, said receiver being connected, in any suitable way, to an igniting device for the explosive charge, or detonator.

In order to make the invention more easily understood I will now proceed to describe a suitable embodiment thereof illustrated in the drawings.

Figure 1 shows diagrammatically the fore part, and Fig. 2 shows diagrammatically the rear part of a torpedo provided with an internal combustion engine and with a mooring device, said torpedo being actuated by a numher of receivers for performing the' functions above mentioned. Figs. 3 to 7 show details. Fig. 8 is a diagram showing the circuits and apparatus for controlling. the engine.

In the embodiment illustrated four receivers are placed at the anterior end of the torpedo, two of said receivers marked 1 (only one visible in the drawing) serving to steer the torpedo horizontally, while the two other receivers 2 serve to steer the torpedo vertically. The one receiver 1 is shown included in an electric circuit 3 comprising a battery 4 and the one winding 5 of a transformer whose other winding 6 is inserted in a circuit 7 including two electromagnets 8, 9 both serving as relay magnets, the one 8 for operating the rudder and the other 9 for closing an electric circuit 10 including the devices for starting the engine and disengaging the torpedo from the mooring. The

non-visible receiver diametrically opposite.

cooperate with three contacts of which the middle one 18 is connected to one pole and the two outer 19, 20 are connected to the other pole of a battery 21. Inserted between the poles of the horse-shoe magnet 17 is apolarized armature 22 connected, by a link 23, or the like, to a valve 24 serving to put the high-pressure chamber 25, or other pressure receptacle, in communication with mamas one or the other end of a cylinder 26 whose .piston'27 is connected to the ruddrs28, 29

' piston 27 is moved from its middle position toward the one or the other end of the cylinder. The receivers 2 are supposed to be connected, in a similar manner, to the depth-' regulating rudders of the torpedo. Normally, a constant continuous current flows through each receiver, which current is transformed into an undulating continuous current,-when the receiver is actuated by waves of sound, or the like When the receiver 1 shown in the drawing is actuated, an alternating current is generated in the circuit 7 whereby the electromagnet 8 attracts its armature 13 and closes a continuous current from the battery 21 through the contact 18, contact 15, electromagnet 17 contact'16, and contact 19, back to the battery 21. According as one or the other of the receivers 1 is actuated by wavesof. sound, or the like, or as one is more intensely actuated than the other, one or the other of the electromagnets 8 and 11 is excited, or the excitation of the one preponderates over the other, whereby the armature 13, which normally takes up the middle position shown in the drawing, is attracted toward the one or the other of the said electromagnets and closes a circuit for the battery 21 through theelectromagnet 17, so that the latter is supplied with current in one or the other direction. On account thereof, the polarized armature 22, which normally takes up a middle position (see also Fig. 3), is caused to turn in one or the other direction, whereby the valve 24 is opened for admitting compressed air to one or the other side of the piston 27. The

rudders

28, 29 will thus be turned in one or the other direction, according as one or the other of the receivers 1 is actuated. The depth-regulation by means of the receivers 2 is supposed to take place in a similar manner, and the arrangements, therefore, need not be described.

The circuit 10' (Fig. 1), which is common to all the receivers, is supplied with current fromthe battery 30, as soon as the circuit is closed by any of the

relay electromagnets

9, 12, 31, 32 (see also Figs. 6 and 7), the electromagnets -12, 31 and 32 being supposed to be connected each to one receiver in the same manner as the electromagnet 9 is connected to the receiver 1 (Fig. l). The circuit 10 will, thus, be supplied with current, as soon as any receiver is actuated by waves of sound. Included in the circuit 10 is an electromagnet 33 serving to control the ignitions of the engine as well as

velectromagnets

34,

, 35 for opening the valves for the supply of air and fuel to the engine (all the ments schematically indicated).

Referring to Fig. 8, theelectromagnets 34,

. arrange- 35 serve to control the supply of air and fuel to the engine. When the said electromag-- nets are energized and attract their armatures, the

supply cocks

61 and 62 are opened and supply the engine with'air and fuel. YVhen the

electromagnets

34, 35 are deprived of current, their armatures are retracted by springs in such positions as to keep the sup ply cocks closed. The electromagnet 33, when supplied with current, attracts its armature 50 against the action of a spring 51 and thereby closes a circuit 52 including a battery 53 and a self-

interrupter

54, 55. When the circuit 52 is closed by the armature 50, the winding 54 of the self-interrupter causes the armature 55 to rapidly swing, so as to break and make the circuit 52. The winding 54 forms the primary winding of a transformer whose secondary winding 56 is connected to a spark-gap 58 forming the igniting device for the engine 59. As soon as the circuit of the battery 30 is closed, the electromagnets 34' and 35 attract their armatures opening the

valves

61, 62 for the supply of air and fuel to the engine, and at the same time the electromagnet 33 attracts its armature 50 closing the circuit for the and are supported, at the other end thereof,

by a hook 40 projecting from the armature 41 of the electromagnet 36. When the latter is supplied with current, the armature 41 is attracted, whereby the hook 40 is moved away from the bearings ,37, so that the latter are allowed to turn about their pivots and let the roller 38 go. The torpedo can then freely move, under the influence of the receivers, toward the object emitting the waves of sound, or the like.

Placed behind the propeller is a rearwardly directed receiver 42 included in a circuit 43 comprising, furthermore. a battery 44 and the one winding 45 of a transformer whose other windin 46 is electrically connected to a device 47 for igniting the detonator. The torpedo is,'thereby, caused to explode, even if it does not hit the object emitting the waves of sound but passes the said object so that the receiver 42 is actuated by waves of sound from behind.

All the receivers should be arranged in such a manner as to dominate only a certain angle, which is easy to afford, inasmuch as the waves of sound, or the like, conveyed first some time after the vice,

through the water cannot enter the funnels of dthe receivers without meeting their open en s.

The circuit 43, or the igniting circuit controlled thereby, is, obvlously, not closed, when the torpedo isejected, but is to be closed, after the ejection of the torpedo, by means of a clockwork, a time-fuse, or any other suitable device. As such arrangements are before known, they need not be particularly described. Also the circuit 3, or the circuit 7, and the corresponding circuits of the other receivers should be closed ejection of the toredo. The circuit 10 should, obviously, not Be made ready for closing before the torpedo has stopped and taken up a vertical position. The starting of the clockwork for closing the circuits, or the ignition of the corresponding time-fuse, can, suitably,beeifected, when the torpedo is ejected. For the sake of simplicity the time-

fuses

48, 49 are indicated in the drawing as contacts separated by insulating material. Each time fuse in the usual manner closes a break in the circuit controlled thereby a predetermined length of time after it has been ignited.

The construction of such time fuses is well known in the art and, therefore, need not be particularl. described.

A-specia advantage of the described torpedo isthat it moves toward the propeller of the vessel to be destroyed and thus strikes the most vulnerable part of the vessel thereby making the latter unable to maneuver.

Arrangements similar to those described may, obviously, be used in submarine boats and the like.
