Definitions

  • FIG. 1 is a view in longitudinal central section of the posterior end of a projectile in which my present invention is embodied;
  • FIG. 2 is a view in cross-section of the fusestock of the projectile of Fig. 1,the plane of.
  • Fig. 3 is a view in section of a locking block in detail in one specific permissible form.
  • That specific means includes in the structure a burster charge and a detonator charge movable the one with respectto the other from remote to adjacent position'-the objectbeing that, in case of premature explor s'ion of the detonator (which in the present state of the art consists of unstable and dangerc-us material), the burster charge will be safe from explosion; but, when once the projectile is fired from a gun, the conditions incidnt to firing and flight will bring det onator and burster charge into relative pos'itions for service; so that, when upon impact the detonator is exploded in proper and intended manner," explosionof t e .burster charge will follow in regular course.
  • My present invention is another specific means of accomplishing the same ends. Or, in other Words, it is another specific invention under the same generic invention noted above.
  • My present invention like my earlier invention referred to, employs a movable member, and thismovable member is controlled "in the'same manner as in the earlier case; but'in this case the detonator is stationary, and the movable member (instead of carrying the detonator from remote ,position to a position of operative proximity to the burster charge)- serves to control the' continuity of a path of detonation transmission, from detonator to burster charge, and in its movement to; carry a section in a train of detonation.
  • this train is ins terrupted; as the projectile is fired froma gun and flies through the air this train is made continuous; so that, whereas before firing explosion of the detonator will be without efi'ect upon the burster charge, after the projectile'has been fired from a rifled gun the ensuing explosion of the detonator will be imparted in intended manner to the burster charge.
  • Detonation is a phenomenon which certain substances exhibit, of exploding, under proper conditions, with extraordinary intensity.
  • a mass of black powder explodes progressively.
  • the chemical changes advance fromthe point at which the impulse is applied to the remote portions of the mass; and, thoughthis progression is'a very rapid one, it is still a clearly discernible progression.
  • a flash is, essentially, a flame a body of incandescent gaswhich, proceeding from its source, may travel across Wide air spaces and through long empty ducts; detonation is a force, an impulse, a'vibration, like electricity, and is communicated through suitable bodies which are, indeed, conductors of detonation.
  • a flash will leap through a passagev onation may be freely carried for indefinite distance, if only the material through which it is carried be proper and be substantially.
  • FIG. 1 indicates a burster-charge chamber within the projectile, and 2a fuse stock for the fuse which is tov detonate the burster chargev within chamber 1.
  • B is a booster charge, that is, a reinforcing charge, intended to receive detonation from the detonator and to impart detonation to the charge within chamber 1.
  • the-safety chamber 14 is a closed chamber within the fuse stock and when. the parts are assembled within the body of'the projectile. Since it is a closed chamber there can be no danger, in case of the premature firing of the detonator, of the spit-ting'out of flame and gas and of the attendant danger to life and limb of those who have to do with the handling of these articles.
  • This pathway may be direct, ortortuous, as size and relative dimensions may require.
  • a runway 3 In this runway is arranged a movable member 6, which under centrifugal force of the .projectile in flight tends to move to the outer end of the runway, but which is normally held at the inner end by a pair of springback centrifugally releasing bolts 1, precisely such as are described in my copending application named above.
  • the movable member 6 ispreferably recessed to receive tion referred to.
  • a detonation pathway in its body is brought into register with the previously interrupted pathway 13, and then the continuity of the pathway is established from detonator D to buster, charge B.
  • the portion of the path-j way which is formed 1n the body of member 6 may conveniently encircle the member 6 being in this case a filling of detonation transmitting material packed or molded into the encircling groove 12, which has this advantage:
  • the member 6 may turn on its own axis, registry of the portion of the pathway formed in member 6 with the portion of the pathway formed in the partition wall and indicated 13will be certain when the movable member is shifted in the manner and to the ends described.
  • a locking member 7 may lie within the 1n- .ner end of member 6; and, by extending the runway 3 across the center of rotation, this locking member 7 will under centrifugal force crowd against the inner end of the runway and be retracted from member 6 as that member moves outward, and then having escaped from the recess which held it, it
  • the locking member specifically illustrated in Fig. 3 is merely exemplary. It is so shaped (having an oblique rear surface) that when fully withdrawmfrom the member 6 it will tip and will not again be in a position to reenter the recess which formerly contained it.
  • the pathway for the transmission of detonation from detonator to. ,burster charge may be such as the intelligent designer may select; it must be of material suitable for detonation transmission as shown (and this is my preference) it is a narrow duct filled with high explosive (preferably tri-nitrotoluene); and, furthermore, the groove in the movable member 6 is in like mani1er filled with high explosive. 'When the duct and groove are brought to register one with the other, there is formed a continuous line for detonation transmission; The pathway for detonation transmission from detonator to burster charge consisting of a. column of such material as tri-nitrotoluene cannot be penetrated by a flash; ig-
  • said path being normally interrupted, and means for establishing the continuity of said path.
  • path of detonation transmission normally interrupted extending from said Copies of this patent may be obtainedfor detonator to said burster charge, and means for establishing the continuity of said path.
  • a fuse stock for an explosive projectile including a substantially cylindrical body dividedaby a transverse partition wall, a detonator within a safety chamber arranged together with its ignition cap on one side of said wall, a reinforcing chargearrang ed on the opposite side of said wall, a centrifugal bolt movable in a transverse runway. in said wall, and a column of detonation-transmitting material contained in part in said Wall and in part in said bolt.
  • a projectile the combination with a Yburster charge, a source of detonation, and a path o-fdetonation transmission from said source to said burster charge, of a runway intersecting said detonation transmission .
  • a larger main body and an attenuated extension and, in combination with the burster charge so shaped, a detonator arranged at the remote end of said extension, and a make-and-break device, arranged in said ex tension of the burster charge.
