MEANS FOR CARRYING AND HANDLING TORPEDOES ON VESSELS.

Specification of Letters Patent.

Patented Oct. 15, 1907.

Application iiled May 5,1905. Serial No. 259,057.

To all whom it muy concern:

Be it known that I, THoMAs .Tosnrn MoRIARTY, a citizen ol' the Uni ted States, residing at Newport, in the county ol' Newport and State of Rhode Island, have invented certain new and useful Improvements in Means for Carrying and Handling Torpedoes on Vessels,`

of which the following is a specification.

lhis invention relates to such vessels or boats, and particularly submarine boats, as are adapted for carrying and expelling torpedoes; and more particularly to such a boat having a torpedo-magazine which is open to the water of flotation, normally, the torpedoes therein being submerged or afloat. The purpose of this featul'e is to obviate a difliculty which arises in the navigation and use ol' submarine boats, that the addition or expenditure of torpedoes disturbs the buoyancy, centcr of gravity and total weight of the boat, and must, therefore be carefully compensated.

lho present in volition employs a magazine open normally to the water of flotation, but the torpedoes are mounted in a rol-.uy carrier and are adapted to be brought one by one into alinement with the expulsion tube, or the fixed portion of the said tube.

The invention will be hereinafter minutely described with reference to Ihe accompanying drawings, and the novel features thm-coi carefully defined in the claims.

In the said drawings, which illustrate an embodiment o1' the invention-WFigure 1 is a vertical, axial longitudinal section through the forward part of a submarine boat, and through a magazine therein embodying the present invention; and Fig. 1n is an enlarged detail View of a controller such as that illustrated in Fig. 1. Fig. 2 is a horizontal section of the forward part of the boat on a slightly smaller scale than Fig. 1, taken along the axis of the nmgazine. Fig. 3 is a sectional detail view ol' the chamber and adjacent parts connected with the Iring valve. Fig. Ll is an elevation, on the same scale as Fig. 2 of the inboard end of the magazine. Fig. 5 is a cross-section of the magazine, and of one ot the tubes of `the carrier, showing the ball-bearing. Fig. (i is an enlarged sectional detail of the ball-bearing for the tube. Fig. T is a sectional detail view of the for ward end of a torpedo-tube and the bulkhead, showing the alining means. Fig. 8 is a longitudinal section on a larger scale than the principal views, of one of the torpedo-tubes. Fig. 9 is a transverse section of the magazine showingl the inner face of the inboard head thereof and parts` lnounted thereon. Fig. 1() is an enlarged detail view oi the inner face of the outer cap of the expulsion tube, showing the war-head controller mounted thereon. Fig. 1l is a modification of the torpedo-locking device seen in Fig. S. Fig. 12 is a sectional view of the torpedo-tube showing the mechanism for operating the rcliel` valves. Fig. 13 is a detail view ol' the locking device o1 the torpedo.

The submarine boat is designated, as a whole, by B.

. The magazine consists of a fixed sheet-metal casing l, preferably of cylindrical form, situated as herein shown at the forward end of the boat and extending fore and aft, its forward end being closed by a bulkhead 2, and its inboard end by a head 3. The casing is supported on a deck or floor 4 in the boat. Extending through the axis of the chamber in the casing 1 is an arbor 5, fixed at its respective ends in the heads which close the ends of the casing, and about this arbor rotate carrying rings 6 (see Fig. 5) provided with apertures 7 to receive torpedo-tubes 8. Four tubes are shown in the drawings, and three rings. These latter form a carriage for the tubes, and are shown in Figs. 1 and 2 as provided with ball-bearings 9 on the arbor 5. The tubes 8 are also each mounted in ball-bearings 9LL in the rings G, as seen in Figs. 5 and 6. In Fig. 6 is seen a block 10, which closes an opening where the balls are admitted one-by-one to the race, said block being secured in place by screws or other suitable means.

In Figs. l and 2, T designates the spare torpedoes in the tubes, the lower one being alined with the expulsion tube 11, which is mounted in a stationary manner in the boat and secured at its inboard end :firmly and tightly to the bulkhead 2, and closed by the hinged outboard cap l2. The water of flotation has access to the chamber C in the boat forward of the bulkhead 2, and has access also, under normal conditions, to thel chamber in the casing l, through an inlet I, controlled by a gate-valve 13, and covered by a hinged grid 14. The gate-valve may be operated through the medium of a hand-wheel 15, bevel gears 1G, and a screw-stem 17, which passes through and rotates in the valve. Obviously, when the rings or carriers G rotate they carry the tubes 8 about with them, the object being to bring each tube 8, in succession, into alinement with the fixed expulsion tube 11, so that said tube 8 will form an inboard extension, for the time being, of the tube 1l. As herein shown, the construction is such that it is the lowermost tube in the magazine which comes into alinement with the tube 11. Means are provided whereby, when the set oi magazine tubes 8 are `carried around the arbor 5, each tube will rotate in its carriers 6 in such a manner that the same side of the tube shall always be uppermost, and this means will now be described with especial reference to Fig. 5.

On the inner face of the head 3 is secured a grooved guide-ring 18, set eccentrically to the arbor 5, with its center directly above said arbor. In the groove in this gu-ide-ring are slidably mounted segments 19, one for each tube 8, and to these segments are pivotally secured at 20, the respective flanged end-rings 21, on the tubes. lt 'will be seen that the ring 18 is of such diameter that the distance, measured diametrically, between two pivot-points 20, is the sameas the distance,

measured diametrically, between the centers of two of the tubes 8. The ends of the tubes 8 do not, normally, touch the plates which close the ends of the magazine. Along the top of the tube 8 is formed a T-shaped channel or way 22, and this channel forms a guide for two

lugs

23 and 23*L (Figs. 1 and 2) on the back of the torpedo.

To hold the torpedo against endwise movement when in the position of spare torpedoes, and also when advanced into the expulsion tube (Fig. 1) there is a locking latch-piece 24, (Fig. 13) which when the torpedo is spare7 (or back wholly within the tube 8), engages or embraces the forward lug 23 on the torpedo; and when the torpedo is advanced into the expulsion tube, as seen below in Fig. 1, said latch-piece engages the rear lug 23a. The locking-latch is coupled by its stem, through the medium of a slot, to one arm of a lever 25, the other arm of which is coupled, through a link, to a slide-rod 26, on the tube, provided with a the cylindrical magazine.

spring 27 adapted through the parts described, to hold the latch 24 in its locking position. In order to actuate the locking latch 24 to release the torpedo at the proper time, there is a slidable operating rod 23, mounted in suitable bearings and disposed near the inboard end of the tube 8, and an intermediate rod 29, slidable in the carrier7 the three

rods

26, 28 and 29 being axially alined at the proper time, so that motion to the rod 26 may be communicated through the rod 29.

The middle carrying ring 6 is supported and moves over anti-friction rollers 30 secured to the inner wall of These are best seen in Figs. 1 and 5. To rotate the carriers and tubes, the inboard carrying ring 6 (seen at the left in Figs. 1 and 2) is provided with teeth like a bevel wheel, and these teeth gear with the teeth of a bevel pinion 31, the shaft of which passes out of the magazine through a stuilingbox and carries a worm-wheel 32, gearing with a screw 33, on a rotatively mounted shaft 34, provided with a suitable crank 35. By means of this device the series of tubes 8 may be brought one-by-one into alinement with the tube 11. The two rings of the carriage that are farthest inboard, are collared on the arbor 5 and theA tubes 8 are slidable in them, but the ring 6 at the outboard end of the carriage has only a stop-collar at its inboard side and is pressed up to this collar by a spring 36. The tubes are not slidable in this ring. The spring 36 embraces the arbor 5 and is embraced endwise between said ring or carrier and the bulkhead 2. The purpose of this construction will be hereinafter explained. i

As before explained the magazine is connected normally with the water of flotation through the inlet I, and the water also fills the tribes 8 about the torpedoes therein; but there is also an upper outlet O, from the vtop of the magazine through the shell of the boat at 37,

where the aperture is covered by a grid or the like to keep out floating matter. This with the two connections 1 and O, with the sea, it will be obvious that the weight of the torpedoes need not b'e considered in `operating the boat, as the expulsion of a torpedo will not in any way affect the buoyancy or center of gravity of the boat.

ln the outlet O is a controlling valve 38, to close it when it is desired to blow the water out of the magazine- This latter may be effected by admitting compressed air to the magazine through a valve-controlled pipe 39. The air will be supplied from a tank, not herein shown; but such air-tanks are common in this class of boats. It may be stated that when it is desired to blow the water from the magazine the valve 38 is closed, the compressed air admitted through the pipe 39, and the water blown out through I. The gatevalve 13 may then be closed. This permits of access to the magazine from the boat for any purpose desired. 1n the inboard head 3 of the magazine and opposite the inboard end of the uppermost tube 8, is a manhole closed by a hinged cover 40, in the usual way. This cover is seen in Figs. l and 4, and the manhole affords access to the magazine when the water shall have been blown out therefrom as explained. There is also an opening in the head 3 opposite to the lower tube 8 which is alined with the expulsion tube. This opening is closed by a cover 4l (Figs. 3 and 4), and has slidably mounted in it a flanged and packed ring 42, the flange of which is adjacent and opposite to the inboard end of the alined tube 8. A screw 43, having a hand-wheel or crank on its outer end, is mounted rotatively in the cover` 41, and screws through the boss of the ring 42, whereby through the medium of this screw, the ring maybe driven inward against the end of the alined tube 3 and the latter be pushed forward until its outboard end bears tightly against the forward bulkhead 2. Said screw is provided with a collar 44, by means of which the screw is held against longitudinal movement in the cover 4l, but is permitted to rotate freely therein.

It may be explained here that this movement of the tube is only effected when the alined torpedo is to be driven forward into the expulsion tube, and in order to assure the accurate alinement of the tubes, a device seen in detail in Fig. 7 is employed. On the outboard end of each tube 8 is a flanged ring having in it sockets or holes 66, to receive pins 67, having rounded ends, said pins being mounted in the bulkhead 2, about the opening therein leading to the expulsion tube. When the tubel is being pushed forward-as seen in Fig. 7,- these pins 67 engage the sockets 66 and bring the tube into accurate alinement and hold it against movement. This endwise movement of the tube will be very slight and will not suffice to disturb thc operation of the Working parts in any way.

The torpedo is moved forward, and is expelled by compressed air; and a device 45, commonly called the firing valve, controls the admission of compressed air (for expelling the torpedo) through a pipe 46, which taps the cover 41. The air is supplied to the firing valve from any suitable air reservoir or holder, not shown, through a pipe 47, a three-way cock 48 controlling its llow to said valve. This three-way cock determines the flow of the compressed air to the valve 45, or to the forward end of the expulsion tube by a pipe 49, or to the chamber (c in Fig. 3) under the cover 41, by a pipe 50. The object of this distribution of the air will be explained later herein.

The firing-valve and three-way cock may both be of known constructions, and detailed illustration and description thereof will not be necessary herein; but it may be explained that the firing valve is operated by a lever 51, which has a depending slotted segment 52, and is locked through the medium of a segmental plate 53 disposed at right-angles to the segment 52 and playing in the slot therein. A spring 54 connects the lever l with an upright arm 55, and returns the lever to its normal position after the firing valve shall have been actuated. The firing valve cannot be operated until the outer cap 12 is opened, and the means for bringing this about as well as for opening the cap will be hereinafter described;

When the valve 45 is opened and the air rushes through the pipe 46 to the chamber c, it forces open a hinged check-valve 56, seen best in Figs. 1 and 3. This valve has a lug on it near its free end which is coupled by a link 57 with a rod` 58, that plays through a stuffing-box and is coupled at its outer end to one arm of a bell-crank leverI 59. The other arm of this lever is coupled by a link 60, with a slide-rod 61, which plays through a stuffing-box and passes into the magazine. This rod 61 will be found at this time, in alinement with the rod 28, and when the valve 56 swings inward and opens, the effect is to cause the

rods

2,6, 28 and 29 to rock the lever 25 and disengage the latchpieec 24 from the lug on the torpedo, and permit the latter to move forward. It should be borne in mind that the rods 29, which are intermediate, rotate with the carrying rings 6; the rods 28 turn with the tubes 8, and the rod 61 is mounted in a stationary part. Hence they will only be in alinement under certain conditions and when the tubes are in certain positions.

The torpedo is provided with the usual starting lever 62, which puts in motion the engine of the torpedo, and this lever 62 is tripped or actuated by ahook-lever 63 when the torpedo is expelled. This lever 63 is disposed in the tube 8, in the path of the lever 62.

1n the upper side of each tube 8, at its forward end, is a recess 64, into which may fold out of the way a spring controller 65, but a spring about the pivotal axis of this controller presses the latter inward and across the interior of the tube in such a manner as to cause its free end to engagrl or take between` the blades of the propeller' of the war-nose `w of the torpedo and hold said propeller against rotation while the torpedo is back and wholly within the tube 8. There is a liability of the said propeller to be rotated when the carriers are being turned to bring a torpedo into alinement with the expulsion tube, and this controller prevents it. When the torpedo is moved forward into the expulsion tube this controller is folded or pressed upward by the body of the torpedo. There is another controller forward at the cap of thc expulsion tube, and this controller will be hereinafter described and its functions fully explained.

1n each of the tubes 8,1iear its inboard end `and at its lower side, are relief valves 68, four of these are shown, but a greater or lesser number may be employed. The purpose of these valves is to allow water to iiow into the tube instantly behind the torpedo and thus compensate promptly for the weight of the torpedo expended. 1t will be noted that when a torpedo has been advanced to a certain predetermined extent and the air-pressure behind it is reduced, an inrush of water may result, and this will tend to retard its movement and perhaps disturb the accuracy of its aim. The opening of the valves 68 will have the effect to counteract the inrush of the water. These valves are operated from' outside the magazine by means of one or more arms 69, adapted to take under the respective valves, and secured to shafts which extend into the magazine through stuffing-boxes. The shafts are provided at their outer ends with an operating handle 69. This handle is seen in Figs. 4 and 12.

The drawings illustrate a submarine boat of comparatively small beam and in consequence of this construction a short expulsion tube is employed to connect the bulkhead 2 with the stem where the outboard cap is situated; and it is with the view of effecting a perfect alinement of the lower torpedo tube 8 with this tube 11, that the device is employed provided with the alining `studs and sockets, as already described. It is also to perfect this alinement that the construction shown in Fig. 9 is employed. i

The outer cap 12 is operated through the medium of a rod 70, coupled at one end to the cap above its hinge, and at the other to one arm of a bell-crank 71. A rod 72 couples the other'arm of said bell-crank to an arm of another bell-crank 73, and the other arm of this last-named bell-crank is coupled by a link 74 to an operating rod 75, which plays slidably through a stuffing-box in the bulkhead 2, and extends back to the inboard end of the magazine, where a rack 76 on the operating rod, gears with a screw 78, rotatably mounted and provided with a crank 79. By means of this crank the cap 12 may be opened and closed.

1n order that the firing valve 45 may be automaticallyY unlocked, at the pivotal axis of the bell-crank 71 is a bevel Wheel which, when said crank is rocked, acts to rock a shaft 80, through the medium of a shaft 8l, and bevel-gears 82, 83 and 84. The rock-shaft 80 extends back to a point near the firing valve, and carries at this end the segment plate 53 which locks the firing valve. The opening of theV cap 12 causes the plate `53 to be moved out of engagement with the slot in the segment 52 and permits the valve-lever 51 to be shifted.

The air-pipe 49, leading from the three-way cock 48 forward to the expulsion tube 11, has for its object to provide, in connection with the pipe 50, means for moving the torpedo forward or aft in the tube by means of compressed air.

The operation may be now explained. The carrier is charged with torpedoes through the upper manhole in the inboard head 3, the carrier being turned to bring the tubes 8 successively into alinement with said man-v hole. When a torpedo is inserted and pushed forward into the tube, the forward lug 23 will move up the latchpiece 24 and snap into engagement therewith. This notifies the operator that the torpedo is in position. When the circumstances call for it-as an impending engagement-the operator presses forward the alined tube 8, lifts the latch-piece 24 by means of a hand-lever 59a on the bell-crank 59, and admits compressed air to the chamber c through the pipe 50. This moves the torpedo in the alined tube forward to the position seen in Fig. 1, when the latch 24 will snap over and engage the after lug 23L on the torpedo and hold the latter in the position attained. The hook-lever 63 will now be in position to engage the starting lever 62 of the torpedo, and the propeller of the war-nose of the torpedo will be in engagement with the forward controller of the device, to be hereinafter described. To expel the torpedo, the outer cap 12 of the expulsion is rst opened and the firing valve then opened to drive the torpedo out. 1n

case-.it is desired to move the torpedo back into the alined tube 8 again and not expel it, this may be done by lifting the latch-piece 24, and admitting compressed 4air to the expulsion tube through the pipe 49.

ment seen in Fig. 1 by a spring 86 (Fig. l0) at its hingeaxis. There is a lug 87 on the back oi the controller, and back of this lug is a pair of spring nippers 77 to grip said lug. A weight 88, pivoted in the cap has a wedge at its lower part which, when the cap is closed, wedges open the nippers. When the cap is thrown open the weighted wedge is thrown back, and the spring nippers are in position to grasp the lug and hold the controller up when the latter is thrown up by the body o the cxpelled torpedo.

In Fig. 11 is illustrated a slightly modified construction of the means for disengaging the latch-piece 24 from the lug 23D. In this construction of Fig. 1l the device is the same as that already described except that the inboard end ot the rod 28 enters a hollow in a piston 89, playing in a small cylinder 90, on the tube 8, said cylinder being connected with the tube by a port 91. The compressed air admitted to expel the torpedo, enters the cylinder through port 91 and drives the piston 89 forward, and the latter thus performs the same iunction as the rod 61. The rod 28 in Fig. 11 plays through a bearing bracket 92 on the tube 8 and has a head 98 on its end which engages the piston. Between the bracket and said head is a strong spring 94, which serves to return the piston to the position seen in Fig. 11 after the air-pressure is relieved.
