Application le. November 7, 1911.

In the example of Figs. 1 to t a plate g which can be attached to the nose of the tore pedo carries four firing tubes fw arranged symmetrically to eacht other and to the axis of the torpedo. The plate g is also provided with a tube t lying in the extension of the axis of the torpedo, in which tube works the percussion needle a. rlhe stiftening and connection of the fo-ur tubes w with each other and with the tube t is eifected by four ribs i and a conically formed end wall L. Each tube w contains a piston-like projectile m. The ends of all these projectiles project from the tubes 'w and carry a ring n having a sharp front edge. ln the charge space of each firing tube w is placed a cartridge v which is discharged when the projectile m, is forced backward by encountering a net.

The percussion bolt which is acted on by a spring j", is held in cocked position by means of a locking pin c, the end of the said bolt then lying behind the plane of the edge of the ring m. The withdrawal of this locking pin c is e a bell Be it known that I, VViLLni/r GoLsTni'rN, a subject of the Kingdom of the Netherlands, residing at Stalpertstraat 16, Amsterdam,

useful improvements in Devices for Cutting or Destroying Torpedo-Nets, of which the reference being acompanying drawing.

devices for cuthad therein to the rlhis invention relates to in which an auxiliary charge is employe the explosion of which actuates a member The invention consists substantially in an improved device of the above type in which a number of firing tubes in the nose of the torpedo and lying parallelto the direction of its travel, contain piston like projectiles of which the ends projecting out of the firing tubes carry, a common ring, the said projectiles'causing discharge of cartridges contained in the firing tubes when they are forced into said tubes by the ring encountering a torpedo net. When a percussion bolt for the discharge of the torpedo is provided in the nose of the torpedo it is necessary that the tearing device sho-nld project beyond this bolt to prevent premature discharge. Owing to this circumstance, when a net is not present z'. e. when the torpedo strikes the ships side directly the torpedo would not be actuated since the ring projecting beyond the end of the percussion" bolt, would prevent the latter from operating. To prevent this, special means are provided whereby when the ring strikes the ships side directly the percussion bolt is securely operated. To increase the destructiveness of the device the ends of the projectiles projecting from the firing tubes may be provided with projecting wings or blades.

The invention is described with reference. to the accompanying drawings, in which the rst four figures relate to an example in which the percussion bolt is tted in the nose of the torpedo while the firing tube for expelling the tearing ring is arranged symmetrically about the percussion bolt.

Figures l and 2 are a vertical axial sectio-n and an end elevation respectively. Figs. 3 and l are sections at A B and C D of Fig. 1. Fig. 5 shows a construction of the tearing device in which the ring is carried by a single projectile which lies in a firing tube arranged in the axis of the torpedo.

ifected by means of crank lever l) mounted on one of the ribs i and having an' arm, lying in radial direction, and in the path of a projection r on one of the projectiles m, a slot 7: being provided in the wall 7L to allow the movement -of this projection. The length of this projection r is such that it only encounters the arms of the bell crank lever b when the projectile m is forced completely into the firing tube fw beyond the limit of firing, which occurs when a net is not present and the projectile m strikes directly the side of the ship.

To increase the destructiveness of the device, cutting wings or blades o may be provided at the front ends of the projectiles m. To insure the discharging of all the cartridges c the charge spaces of all the firing tubes lw may be connected by firing channels.

The device operates as follows: Vxhen the torpedo strikes the topedo net, the projectiles m? owing to the small resistance of the net are driven into the tubes only far enough to effect discharge of the cartridges fv. The projectiles m are thereby fired cut of the tubes w andthe ring n. impelled against the net with the combined velocity of the torpedo and projectiles m thus tearing the net and enabling the torpedo to strike the side the ship without obstruction. VV hen the torpedo strikes against the side of the ship the end of the percussion bolt t projecting beyond the tube t encounters the side of the ship and isvfo-rced into the firing position owing to the simultaneous shearing of the locking pin 0 and the action of the spring j'. 'Io prevent the percussion bolt a from glancing off the side of the ship, the end of the bolt is made concave. If the Aship being attacked is not provided with torpedo nets the ring nstrikes against the ships side directly. The projectiles m are thereby forced inward but the expelling effect of the exploding cartridges v is not exerted owing to the kinetic energy of the torpedo, the projectiles m in spite of the explosion of the cartridges being driven farther into the firing tubes. fw.

In order to render certain the firing ac tion of the percussion bolt a'behind the plane of the front edge of the ring n also in the case when the 'projectiles fm, and the ring n are not r'ed out, the previously described arrangement of the releasing lever b and projection 1 is provided. In this case the projection 1 of the projectile m which is forced back, will rotate the lever I) to the left thus lifting the locking pin c' out of its n'ormal position and freeing the percussion bolt a..

.The modification shown in Fig. 5 isspecially applicable in conjunction with firing mechanisms of the known type in .which by, means of a percussion bolt arranged in theinterior ofthe torpedo and set inaction by the. inertia of a `movably mounted'l heavy body when the torpedo strikes against al ship. In this modification the ring n for destroying the torpedo net,instea d .of beingmounted on a number-.of projectiles, is carried by a single projectile ring which along withl a cartridge o is located in.v a -w` in the axis ofthe torpedo.

I-Iaving now particularlyu'described nd.` ascertained the nature of my said invenlg n,

and in what manner the same is?` to be p r-l formed, I declare 'that what I claimis:

l. In a device of the character descrilcd ring tubes inthe nose of the 1torpedo-and disposed parallel to the direction of their. travel, piston like projectiles, insaid ltubes",-

3. In a device for destroying torpedo nets comprising firing tubes in the nose of the torpedo and disposed parallel to the direc- -tions of their travel, piston like projectiles in said tubes, a ring carried on the projectingends of said projectiles, cartridges in Vsaid firing tubes discharged by said projectiles when they are forced into said tubes 'by the ring encountering a torpedo net, a *l spring actuated percussion bolt, a locking the firing of the-torpedo charge .'isiefect'ed j vpin releasably holding said percussion bolt, until the piston like projectiles are driven deeplyy into said firing tubes'and a cuttingI g j blade on the ends of said projectiles.

In testimony whereof I hereunto affix my i' signature in presence of two witnesses.
