Definitions

  • This invention relates to projectiles for use in rifles and like iirearms, and particularly to their structure.
  • Explosives may in general be classed in two groups, to wit, explosives of the burning type, and lexplosives of the detonating type.
  • an explosive of the burning type is generally employed, as this produces a large volume of gas under high pressure which functions as the propelling agent for the projec tile.
  • Fig. 1 is an enlarged central longitudinal section of the projectile
  • Fig. 2 is a similar enlarged section of the rear end of the projectile
  • Fig. 3 is a section of the primary detonating charge, to wit, iulminate of mercury or the like;
  • Fig. 4 is a perspective View of the main detonating charge
  • Fig. 5 is a longitudinal section of a portion of a rifle showing the projectile placed therein in position to be fired.
  • the projectile is fairly long and has a main body portion A terminating in a closed, pointed forward end 2.
  • a longitudinally extending chamber 3 is formed within the projectile, which is open at the rear end and terminates in a iiat face 4 at the forward end.
  • the body of the projectile is made of steel as forces generated within it are large.
  • the explosive charge employed is Vor the detonating type and is placed directly in the chamber 3.
  • the charge is divided into two sections, indicated at B andC, and while both are of the detonating type, one, to wit, the section C, is made of a more sensitive type, such as fulminate of mercury, whilethe other vmay be of a less sensitive type, such as trinitro-toluene, or the like.
  • Trinitro-toluene has been found satisfactory as it may be compressed and ⁇ molded into sticks b which are provided with a recess -6 at the inner end and a cone-shaped chamber 'l at the outer end.
  • the waves produced by detonation travel in the direction of arrows a, with a velocity of several thousand meters per second, and as the brisance or violence of the blow produced by the waves of detonation are directed against the flat face 4, the projectile will be propelled in a forward direction with a velocity proportional to the intensity of the Waves absorbed in the forward portion of the projectile.
  • Waves produced by the burning gases are also traveling in a forward direction with substantially the same velocity, and these waves also impact against the face 4 and thereby further aid in in- 3 creasing the total force and increasing the velocity of the projectile when red.
  • rIhe pressure of the gases produced may be utilized to a certain extent but is not depended upon, as the bolt head structure in this instance is such that the moment gas pressure reaches a predetermined point the bolt begins to recede and the gases are then permitted to discharge and vent themselves to the atmosphere, such release of the gases being desirable as heat is thus quickly liberated and dissipated, permitting a gun or rifle of this character to be used for rapid re, such as machine guns and the like, without excessive heating.
  • the disc 8 which retains and seals the main explosive charge and the primary detonator, is both combustible and explosive in itself and is, of course, completely converted into gas just as the main and primary charges are when the projectile is detonated. Hence, when the projectile discharges from the end of the barrel and the gases have escaped, no residual matter will remain and the barrel is thus clean and open to receive the next projectile. v
  • a projectile of the class described comprising, a cylindrical body portion terminating in a pointed forward endA an elongated chamber formed within the projectile, open at the rear and terminating in a flat face adjacent the forward end, a wave producing propelling detonating explosive filling the major portion of the chamber said charge having a cone-shaped chamber formed in its forward end with the base of the cone adjacent the nat faced end of the chamber in which the charge is placed, a primary detonating explosive charge rearwardly thereof, a disc of explosive material covering the primary explosive, and means for retaining said disc and both charges against removal from the chamber.
  • a projectile of the class described comprising, a cylindrical body portion terminating in a pointed forward end, an elongated chamber formed within the projectile, open at the rear and terminating in a ilat face adjacent the forward end, a wave producing propelling detonating explosive filling the major portion of the chamber said charge having a cone-shaped chamber formed in its forward end with the base of the cone adjacent the flat faced end of the chamber in which the charge is placed, a primary detonating explosive charge rearwardly thereof, a disc of explosive material covering the primary explosive, and an annular groove formed in the inner face of the chamber adjacent the rear end thereof -to receive and retain the disc in engagement with the primary charge.
  • a projectile of the class described comprising, a cylindrical body portion terminating in a pointed forward end, an elongated chamber formed within the projectile, open at the rear and terminating in a flat face adjacent the forward end, a molded compressed wave producing propelling explosive detonating charge filling the major portion of the chamber, a primary explosive detonating charge disposed in Contact and rearwardly thereof, means for sealing and retaining both charges within the chamber, and a coneshaped chamber formed in the forward end of the molded compressed charge to concentrate and direct the said propelling waves produced by detonation against the flat face at the forward end of the chamber in unison with a detonation wave produced by detonation of the explosive detonating charges.
