Definitions

  • This invention relates to high explosive shells used in war-fare. that class of shell used in naval war-fare.
  • the object of my invention is to produce a projectile which will leave the muzzle of a gun at a very much greater velocity than the projectile at present in use, and wh1ch w1ll, at a point in its flight, pro ect from within itself an ordinary or high explosive shell, thus increasing the range of ordnance.
  • the projectile comprises what may be termed a casing, wherein an ordinary or h gh explosive shell is placed.
  • the said casing is made to fit the bore of a gun, and is as light as is practicable.
  • the force of the explosiori'in the gun operates on an area equal to theb'ase of an ordinary shell, giving a greatly increased velocity, mainly on account of the considerable reduction in the weight of the combined casing member and pro-' jectile, and during the flight of my shell, by reason of the loss of its outside casing, the weight of the projectile continuing in flight is reduced approximately to half that of an ordinary shell. This gives a much greater range than if an ordinary heavy'shell was fired from the same gun.
  • an explosive charge set with a time fuse is placed in the base of the outer containing shell, so that at the required time, after leaving the muzzle of the gun, the charge will explode, projecting forward the inner shell, thus adding to the velocity already attained.
  • Figure 1 is a view in section embodying one form of my invention.
  • Fig. 2 is a view in section embodying a form of my invention for use when it is desired to shatter the outer casing.
  • Fig. 3 is a section on the line A-B, Fig. 1, showing means to transmit a spinning motion to the inner shell.
  • the main parts comprise an outer casing 1, wherein an ordinary or high It relates also to explosive projectile 2 is housed, the outer casing is made suitable to theebore of the gun, and the inner projectile is a free fit in the casing.
  • the middle part of the outside casing is reduced in diameter to lessen the weight, as at 3, and has at its base part small holes 4 penetrating 'to the bottom of the inner projectile to allow free access of air to prevent a vacuum being formed.
  • the diameter of the outer casing and inner projectile are so proportioned that the sectional area of the outer casing-will be greater than the cross sectional area of the inner projectile.
  • the type of shell illustrated in Fig. 2 comprises a casing 1 adapted to house the projectile 2.
  • a casing 1 adapted to house the projectile 2.
  • the casing in this form also has its base provided with holes or transverse ways 4 penetrating to the bottom of the inner end of the projectile to allow free-access of air to prevent a vacuum being formed.
  • the spinning motion is transmitted to the inner shell by means of the lug or clutch 2 which may be attached to the base of the inner projectile and fit into a corresponding shotnll formed in the base of the outer s e 16" gun under the conditions of my system, the area of the shell being approximately 50", and its casing approxlmately 201", it is readily observed that under the explosive force of 1000 lbs.
  • the 8" shell would be projected from the gun under a total force of 201,000 lbs., while if a shell 8 in diameter is fired from a gun under the conditions of the system at present in use, with the same exploslve force per square inch as above, the total explo sive force would only be 50,000 lbs; therefore, a projectile discharged from a gun under the conditions of my system would have four times greater explosive force behind it than if discharged under the conditions at present known. It follows that, if I makemy shell considerably longer than llhe following remarks are set forth to illustrate the efficiency of my invention.
  • a projectile comprising a casing adapted to fit the bore of a gun and rovided with a recess extending inwardly rom one end,-
  • said casing having a blunt forward end to offer head resistance for retarding its flight to rmit the ejection of the projectile there rom during flight, explosion Frovi ed rom one.
  • a projectile comprising an outer casing, an inner projectile partly housed in saidcasing, and means for shatterin the casin at a predetermined time during ight to re eve the inner projectile of the wei ht thereof for continuing the flight of the inner projectile
