Application filed November 30. 1887. Serial 110.856.568. (No model.)

To aZZ whom iii-may concern:

Be it known that we, JAMES OKELLY, of 65 Besshorough Street, London, England,journalist and member .of parliament, and BER,- NARD AMBROSE COLLINS, of 26 Machell Road, Nunhead, Surrey,England, meteorologist, subjects of the Queen of Great Britain, have invented certain new and useful Improvements in or Connected with Torpedoes. of which the following is a specification.

The invention-relates,first,to means whereby, in the event of torpedoes encountering netting defenses, they shall be capable of attaching themselves thereto and of diving under the nettingor jumping over the netting-boom and efiectnally strike the object aimed at.

The invention relates, secondly, to means for preventing torpedoes from rotating around their own axis and for causing them to remain :3 at any previous]y-determincd depth of immersion in the water.

In order that our invention may be clearly understood and readily carried into effect, we will proceed to describe the same with the aid 2: oi the accompanying drawings.

v Figure l is a vertical longitudinal section of part of a torpedo constructed according to our invention. Figs. 2 and 3 are respectively an enlarged vertical longitudinal section and a' 0 sectional plan of part thereof. Fig. 4 repre' seats a slight modification of part of Fig. 2. Fig. 5 represents a slight modification in the construction and mode of connection of the attaching and radius pole to the torpedo. Fig.

Fig. 7 represents a modification in the construction and position of the attaching and radius pole of the torpedo. Fig. 8 is a diagrainrepresenting the action of the torpedo shown at Fig. 7. Fig. 9 represents anolher modification in the construction of the appa- 5 ratus for attaching the torpedo to the netting defenses and directing it to the ships bottom,

- and Fig. 10 is an enlarged view of part-of Fig. 9. I. Y

in all the figures like parts are markrd with similar letters of reference.

The following is a description of the apparatus represented at Figs. 1 to 6.

To use a pole or tube, a, of steel or other suitable material, preferably about one inch in diameter and of such a length as will suit the 5 torpedo upon which it is placed, so that the lance-head a ot'lhe pole or tube a shall project a suitable distance from the nose of the torpedo, for the purpose hereinafterexplained.

lhe pole or tube a is fixed to the torpedoin either of two ways-one, as represented at Fig.

l, by fitting the rear end of the, pole a with oval or flat shaped trunnions afiwhich are fixed at an angle in relation thereto and lock in fulcra or lugs 11, fixed on the back amidship of 6 r the torpedo I), such lugsor fulcra b being formed with openings b through which the trunnions a pass either for connecting or disconnecting the pole at with the torpedo. The other method of connecting-the pole a with the torpedo is represented at Fig. 5, in which case the rear end of the pole a. is forked and fitted with hooks a to fit onto oval or fiat shaped trunnions b fixed on the sides of the torpedo also amidship. In either case the 'pole a, will remain secured to the torpedo b as long as they remain parallel with each other, and-when they form any angle greater than thirty-six degrees,

or other given angle,the trunnions c or I) will pass through the openings in the fulcra or lugs ,80 I) or in the books to, thereby completely disengaging the torpedo from the pole a, except 1 that it is connected thereto by a line, 0, as hereinafter described.

The pole a, with lance'hcad a, may also, as 8 q shown at Figs. 7 and S, beattached to the bot tom of the torpedo, in a similar manner to that described above with respect to the top, in which case it is formed of two or more sections connected together by rule-joints a, so as to obtain any required direction at the moment of striking the netting. The rule-joint a is,

when in the position shown at Fig. 7, held rigid by the tuberd extending over the same; but

when the torpedo strikes the netting the tube 5 a is driven'back against the tube a, so as to free the joint a. The adjaccntcndsofsaid tubes are formed as shown in the enlarged view, Fig. 7, and a stop, a, is provided to limit backward motion of tube a". IOO

To the pole, as shown at Fig. 1, we secure one or more strong springs, d,in such a manner that when the pole and torpedo are parallel with each other the spring or springs d are compressed between the pole and the back of the torpedo; but when the spring or springs d are free toact they will assume an angle of about ninety degrees, or other required angle.

The pole to and torpedo are held together in the following manner: On the pole a, about two feet (more or less) behind the nose of the torpedo when it is in position thereon, we secure-a knife-edge plate, a. This plate a ex tends downward, so as to touch the head of the torpedo when the springs are compressed, as before described. To the knife-edge plate a is hinged a'steel bar or trigger, a, the lower end of which forms a latch that catches under a slight projection, I), on the head of the torpedo. The upper end of said bar or trigger a is forked, so as to pass on either side of the pole a.

The knifeedge plate a is so shaped that the trigger a, when pressed from the front on the forked end, will completely disengage itself from thetorpedos head, and thus allow the compressed springs d to act. t

The trigger a, when in position-that is, when holding the torpedo and pole to together with thesprings compressed between them-is held so by a small spring, of, placed between it and the knife-edge plate a sothat no force other than that to be described can cause the latch or triggera to loose its grip on the torpedos head. a

In front of the forked portion of the trigger a an outer tubing, a is placed on the pole at. This outer tube, of, moves freely within certain limits backward on the pole at upon force being applied from the front. ltis held in position with its rearend about two inches from the trigger-fork a by a small spring, a, which is secured to the inner pole, a, so that the force exerted must be sufficient to compress the spring a before the outer tube, a", can move back to the fork of the trigger a".

, The front end of the outer tubing, a, is fitted with a knife-edge plate, a of sufficient length to prevent its passage through the links of the nettings used for the defense of warships. The lance-point a of the pole a is in the form of a harpoon-head, having two or more cars that lie back while the head is passing through the net-links, and spring open again as soon as it has passed clear through. This prevents the pole a from disengaging itselffrom the netting when it has once struck.

To the pole a, preferably at the l cnife-edge plate a the end of a strong wirc or hemp line, 0, is secured. This line is preferably about thirty-five feet long, but may be of other conv'enicnt length, and it is wound on a reel placed within a chamber, b next that, 11", holding the exploding charge. The action of this line will be described fart-her on. I

Immediately over or around the firing-pin e at the nose of the torpedo we place one or more springs, b the back end or ends of which are not attached to the torpedo, so that when pressure is exerted on the head of the torpedo from any direction other thanthat from the front the spring or Springs 1) will resist, so as to prevent the charge from being exploded; but when the torpedo strikes head on the spring orsprings b will offer no material resistance and the firingpin Q will be driven back. The firing-pin 0 above referred to consists of a rod of steel, which is inclosed in a tube, 6, that leads to the center of the charge from the nose of the torpedo. At its rear end is secured a small casing, 0 of glass, containing fulminate of mercury or any other substance that will explode on concussion.

The forward end of the steel rod 6 projects about two inches, or double the distance between the fulminate-casing e and asteel block, 0, upon which it strikes when driven bark, and the head is formed into a button shape of about one inch in diameter. The steel rod or firing-pin e is held in position-that is, with its rear end about one inch from the explodingblock eby a spiral spring, 0, which winds around it and between it and the tube 6, through which it passes.

For the purpose of preventing the rotation of the torpedo around its own axis during its progress, we fix thereto a keel, 1)", running, preferably, from the nose to the tail, but being almost flush with thebottom of the torpedo at its greatest diameter. \Ve also fix theretoa horizontal fin, I)", at each side of the torpedo, midway between the nose and the tail, which not only serve to prevent the torpedo from rotating around its axis, but are operated in the following manner for the purpose of enabling the torpedo who kept at any required distance previously determined upon beneath the surface of the water: These fins b are secured at their centers to a shaft, b", which passes through the tor-v pedo, so that they can be moved to form any desired angle with the axis oflthe torpedo. To the shaft b is secured a beam lever. 4), extending fore and aft of such shaft, so that if the front portion of said lever b is depressed the front half of the fins b will also be do: pressed, and cause the torpedo to descend by reason of the force of the water acting on the inclined fins. On the other hand, when the rear portion of the beam-leverl) is depressed the fins b" will assume such an angle with the horizontal that the water acting upon the lower surface of the fins will cause the torpedo to ascend upon a gradual incline. To thefrout portion of the said beamlever b we hinge a vertical rod, '1), which moves freely up and down within certain limits in a tube, Z1. Outside this rod b",'or in any other suitable connection with it, we place a spiral .or other spring, 11, capable of being set to exert any desired pressure upon the front portion of the V the water on every part of the torpedo will said beanrlever b by a screw, 1), operated by a key or other suitable mechanism. To the end of the rear portion of the beainlever b we secure another vertical rod, b bya hinge. The upper end of this rod I) is secured by a hinge to the plunger 1)" of a cylinder, I), of, say, from tour to six inches diameter and of suitable depth. The top of said plunger 1) is convex, and .when the fins 1) are perfectly par allel with the axis of the torpedo it is flush with the outer skin on the back of the torpedo; but even when the front portion of the beanrlever b is depressed the convex surface of the plunger 1)" willnot exert any retarding influence on the progress of the torpedo.

At Fig. 2the vertical rod 1) is shown hinged to the beamlever b and to work in the tubular screw b, the lower end of which latter acts to regulate the pressure on the spring I); but ih the modification represented at Fig. at the vertical rod b: is disconnected from the beamlever b, and is fitted with the screw I), while it has formed on ita boss or flange which acts to adjust the pressure on the spring b. The plunger 1)" is covered with a water-proof elastic cover, I), which,while allowing the pressure ofthe water on the plunger b", will effectually exclude the water from the chamber b containing said apparatus.

The operation of the above mechanism connected with the side fins, I), is as follows: Suppose the area of the plunger b" represents one-fifth of a square foot and the torpedo were required to keep at, say, thirty feet below the surface of the water. A pressure ofthree hundred and eightyfour pounds is placed upon the spring I) on the front end of the beam lover I), and consequently the front of the tins will be depressed tot-heliinit they can reach. The torpedo,when d ischarged,will in moving forward cause the water to act on the upper surface of the finsb, and as they are at a descending angle with the horizontal the torpedo will gradually descend. Now, as the pressure of increase with the depth to. which the torpedo descends, the pressure exerted at, for example, the depth of thirty feet upon the upper portion of the plunger b will be 301K646: 5:384, consequently the pressure on the. plunger will equal that on the spring I), and i he fins Z2" will be brought into a horizontal position, so that the torpedo will neither ascend nor descend. if from any accidental causeit descends lower, the fins will be depressed in the rear and the torpedo will rise, and if it ascends the fins will assume the position first described and cause it to descend.

Torpedocs constructed as shown at Fig. 1

are intended to act as follows: The pole u,hav-

. ing the spring or springs 11 attached, is locked at the'centcr ofthe torpedo in the inannerde- I scribed and shown. ltis then pressed forward i so as to compress the springs d and bring the -harpoon-head aini mediately in frontofthe nose of the torpedo. The trigger or latch a is then caught under the projection bfland t e mechanism is then ready to act. The torpedo is then launched in the direction of the objectivevessel, and it is propelled by means well known, but which it is unnecessary further here to refer to. \Vhen the netting around the warvessel is reached, the harpoonhead a passes through the links and cannot release itself again, owing to the cars, which spring open, as before described. After the harpoon-head a passesthrough, the linksof the netting come in contact with the knife edge plate a on the front of the outer tubing, a; with the result that the said tube is driven back against'the forked portion of th trigger ct. The trigger is therefore forced out of its vertical position and its lower end is disengaged from the head of the torpedo. When the pole at is released, the springs d begin to act, and as the torpedo canno't inore forward its head is depressed until it reaches the angle of thirty-six degrees or other fixed angle with the pole at. The oval trnnnious then slip through the slots in the fulcrum or books, thereby releasing the torpedo from the pole a, and the torpedo then dives clear of the pole a. As the torpedo dives the line a pays out until the thirtyfii'e feet or other length is reached. Then the direction of the torpedosinovement is changed, and it has to describe a circle of which the thirty-five-foot line is the radius. Hence, no matter at what angle the nettingis struck by the torpedo, that angle will be followed by it describing the circle mentioned,

and it cannot fail to bring the torpedo in contact with the hull of the vessel. If the nose of the torpedo strikes the netting while diving, the spring or springs I) will protect the firingpin 0; but when the torpedo strikes the hull .of the vessel head on, the charge cannot fail to explode. Vhen using the pole a having rule'joints, as represented at Figs. 7 and 8, we obtain an upward direction with or without the useof springs d for thepurpose of clearin'g the netting-booms on the surface of the water; but, supposing a pole a with rulcjoints is attached to the top of the torpedo in the posit-ion shown at Fig. 1, we obtain a downward direction of the torpedo and accomplish the work in the same manner as described with rcspect to Fig.

in the modification represented at Fig.5 we

. form the outer tube, a long enoughto inclose lhe lnirpoon head u of the pole a, and we give it a longer traverse, so that in the event of the torpedo striking the side of a vessel without previously attaching itself to the netting defenses the outer tubing, a, shall be driven back and the latch a operated to release the pole a. in a similar manner to that described with respect to the arrangement shown at Fig. 1. K

in the modification represented at Figs. 9 and 10 we connect the line 0 at one end to the torpedo about midway between the nose and the center thereof. .The other end of thisline is secured to a fish or other shaped float, f, so arranged that when the torpedo is moving through the water the float f will move parallel with and above it the distance allowed by the line 0. The said floatf is provided with fixed finsf'j' f and with the harpoon-head a, which in Fig. 1 is shown attached to the pole a, so that if it comes in contact with the netting defense of a war-ship it will attach itself thereto, and, as the line 0 will not permit the torpedo to move ahead,it will cause it to'de scribe a circle upward toward the'vcssels bottom. the radius of which circle will be limited by the length of the line. The said fioatf is housed upon the back of the torpedo'byrneans of a steady-pin, as shown;- in such a manner that when the torpedo is launched the float will imn'ie'diately be released from such stcadypin and take up its position and continue to move parallel with the torpedo. Thetcndency of the float will be slightly toward the surface; but this will be counteracted and the depth of itsinimersion regulated by thedepthregulating mechanism of the torpedo.

Having now particularly described and ascertained the uatureof our said invention and in what manner the same is to be performed, we declare that what we claim is- 1.
