  • the said disc 32 is provided with projections engaging the grooves 31, and with blades 33 adapted to impart rotary motion to the projectile when fired.
  • the projectile here is composed of a metal body or bottle 3 filled with liquid carbon dioxide, a plugging member 4*, a cap or nose piece 1 in the form of a shell, and an intermediate piece between the head 1 and body 3. Screwed in the head 1 is a sharp point 14 provided with cutting ridges to ensure easy entry of the projectile, and if desired with ignition means (not shown) for the shell. Pivoted to the intermediate piece 80 are spring loaded folding barbs 21 similar to the claws 21 in Figure 3. Pivotally mounted in the plugging member 4 is a number of spring loaded L shaped folding barbs 35 held in their inward positions (shown in full lines) as long as the projectile has not left the gun nuzzle.
  • the inturned legs of the said barbs 35 are provided with sharp points on their inner faces. As soon as the projectile leaves the gun-muzzle (not shown) the folding barbs 35 swing outward into the positions 35 in which they are held by spring catches 39 and in which positions the sharp points on the inturned legs do not yet project from the projectile body. When the projectile enters a whale-body the said barbs 35, owing to the resistance offered by the object, are forced into their positions 35 against the action of the catches 39. The plugging member 4 is now prevented by the outturned legs of the barbs 35 from entering the object, whereas the sharp points on the inturned legs grip the flesh so that the entry-hole is firmly plugged up.

  • projectiles constructed in accordance with my invention may for the main part be used over and over again after being removed from the whale or other body, whereas the known inflating whaling projectiles, owing to the heavy explosion caused thereby, will be blown to pieces and completely lost.

  • the tubular part 48 is provided with holes 52 which with the ring 49 form a valve so that the inflating gas is released when the ring 49 slides forward when the projectile strikes and/or when the charge in the nose of the projectile explodes, and escapes into the whale or other mammal through the recesses 44.
  • the ring 49' may be held in the closed position by springs, a shearing device or other suitable means.
  • the escape of gas is controlled by asleeve 53 which is operated by the products of explosion of the explosive charge in the nose of the projectile.
  • the sleeve 53 slides on the tubular part 54, introduced into the bore of the forepart of the projectile.
  • the pivoted claws 21 also act on opening out on a disc 55 or similar device.
  • a rod 56 or other suitable device is pushed inwards by the effect of the explosion in the nose of the projectile, and the said rod acts on the sleeves 53 thus ensuring positive release of the inflating gas which escapes through a hole 57 or holes in the tubular part 54 and a slot or openings 58 in the sleeve 53 and then through the openings 44, and slots 44 into the body of the whale.
  • the sleeve 53 may beheld in the closed position when the projectile is fired and during flight by suitable means.
  • the disc 55 is prevented from sliding rearwards by a shoulder 56' on the rod 56 so that the, rod 56 will be pushed inwards (and thus cause the gas to be liberated) also by the action of the claws 21 when opening out.

  • the gas is conducted into the whale body through the holes 66' and cavities 67'.
  • FIG 13 shows in section a further modified construction of the rear end of a whaling projectile in accordance with the present invention.
