Definitions

  • This invention relates to a water bomb designed to destroy submerged objects, said bomb, comprising a iioat which, as is well known in submarine-water mines, detaches itself from the bomb proper when the complete bomb is thrown into the water, remaining connected with it only by means of a cable or rope.
  • the cable is not attached directly to the bomb, but is normally in connection with a percussion primer, which is designed to operatey a time fuze adapted to ignite the explosive charge by the intermediary of a detonator.
  • a percussion primer which is designed to operatey a time fuze adapted to ignite the explosive charge by the intermediary of a detonator.
  • This percussion primer though the bomb be ready Jfor use is normally not under tension but will be put under tension through the aid of said rope only at a predetermined moment when the bomb, after being thrown overboard, has reached a certain depth.
  • the time fuze adapted to be operated by the percussion primer comprises a number of fuzes of different length from which one or the other can be selected and brought in operative position in which it may bridge the space between the primer and the deto'nator by adjusting a rotatable drum carrying the said fuzes.
  • the invention further contemplates the determined point of the circumierences of p the drum.
  • fuzes or fuzing compositions of different lengths can be arranged in such a manner that they can be easily inserted between the point of culmination and the charge and moreover that though there is only a comparatively small space at hand in bombs of this den scription for a time fuze, yet sufficiently long uzes may be employed for determining unusual long intervals after which ⁇ the explosion is to take place.
  • Fig. 1' is a longitudinal section of the complete water bomb ready to be ejected.
  • Fig. 2 illustrates the time uze.
  • the water bomb consists of the receptacle b filled with the burstingcharge a, of a casing c for the time :tuze and the percussion primer, and of the floater d loosely mounted upon said casing so that it detachee itself from said primer when the bomb is being thrown, said floater being connected with the percussion primer m through a rope r.
  • the percussion primer m consists of a spring influenced percussion pin a, Ethe upper ball ⁇ shaped end of'which is gripped by pincers 0 which are broughtinto an enlargement of the primer tube when the pin is beingv 7pulled out so that said pincers open and release the percussion pin which, through Ythe actionl of the spring is made to strike upon the priming cap p located in the inner or lowerrv end of the primer tube.
  • the float d is mounted with. its ⁇ flange upon the casing 0 so that it can detach itself easily from its seat and it carries in its front end a rope drum 'guponfwhich'afr'opew is wound which is attached on the other hand to the pincers 0. Vhen the bomb is being thrown, the float detaches itself from the casing c and is turned upside down through the pull of the rope r which unwinds from the drum, this drum Q being now underneath.
  • the percussion primer m is oper- ⁇ ated through the weight of the bomb and ignites the time fuze.
  • the time fuze is constructed as Jfollows: Upon a cross shaft L rotatably mounted in the side walls of the casing c, six discs t' or" sheet metal are keyed at short distances apart in such a manner that their rims extend from the priming cap p to the detonating cap g, only very little play being left between said rims and said caps. rllhe discs z' are connected the one with the other at the rims by means of ten wood blocks o. Between two of these wood blocks o a metal tube j is mounted which is closed at the inner end and serves for producing the dead point position. Five fuzes 7J are fixed between said discs i (one fuze between every two discs).
  • Each fuze is fixed with its ends to two opposite wood blocks o (Fig. 2).
  • the fuzes Ic are of different lengths and possess consequently diiferent fuzing times.
  • any of the fuzes 7c can be brought into such a position that one end is opposite to the percussion cap y), the other end being opposite the priming cap g, so that the interval between the ignition of the fuze by the percussion cap p and the detonation of the bomb can be regulated at will.
  • the adjusting of the fuzes is effected by means of a lever Z mounted upon the outer end of the shaft 7i, said lever having a stud designed to be inserted in one of six holes of a disc which can be rotated so that either the metal tube j or one of'the five fuzes 7c stands opposite the percussion cap p.
  • the metal tube j stands generally opposite the percussion cap.
  • One of the side walls ofthe rope drum Q has three slots and upon its outer surface a locking bolt s is arranged.
  • the rope r of the float has three loops at points which correspond with determined depths of submersion of the bomb. VThese loops are put through the slots of the side wall of the drum and the ⁇ locking bolt s is inserted throughthe same.
  • the locking bolt is adjusted so that itk releases one, two or three loops according to the depth of submersion. It the bomb has to detonate upon the bottom of the sea, a thin copper wire is placed in the .first loop which can be fixed to the end ot' the locking bolt and the rope is cut through vatV vthe second loop.
  • I claim 1 In a bomb designed to be submerged in water, the combination of an explosive shell having a separable float loosely attached thereto by a rope, a percussion primer in said shell connected to the end of said rope ⁇ a detonator adapted to ignite the explosive charge within the shell, and atime ituze intermediate the primer and the detonator and adapted to ignite the detonator a predetermined interval of time after the primer has been tired owing to the pull on the rope by said float, the time fuze comprising a rotatable drum embodying a series of fuzes of different lengths each of which is adapted to bridge the space between the primer and the detonator according to the adjustment of the drum.
