Definitions

  • This invention relates to a new and improved regulating mechanism for the clockwork of mechanical time fuses designed for artillery projectiles.
  • a further object of the invention is to provide means to counteract the effect of the shock upon the torsion spring extending along the axis of the projectile upon the firing of the projectile and also to protect such spring from the strain imposed thereon due to the weight of the pendulum itself.
  • a further object of the invention is to provide a resilient support for both the torsion spring and the pendulum support thereby.
  • a further object is to provide means whereby all strain is removed from the regulating spring.
  • Fig. 1 is a cross sectional view of the head of a projectile with the body thereof shown only partially.
  • Fig. 2 is a plan view of a detail.
  • the pendulum is shown at I and the regulating spring formed as a torsion spring and consisting of a steel wire, for example, is shown at 2.
  • the clockwork for the fuse has been omitted from the drawing since the invention has reference 56 only to the regulating mechanism therefor.
  • the 'I'he pendulum I and the regulating spring 2 extend along the axis of the projectile whose conical shell head is shown at 3.
  • the lower pivot of the pendulum is mounted in the body 4 of the projectile on which the head 3 is screw threaded.
  • the upper pivot for the pendulum is seated in a dulum I is located.
  • the plate 8 is connected to the body 4 of the projectile by means of the screws II of which only one is shown on the drawing'.
  • the shaft of the pendulum extends through a bore I2 provided in the plate 8 and an upper bearing I3 and a lower bearing I4 is provided for such a shaft.
  • the torsion or regulating spring 2 is connected at its lower end to the sleeve member 5 and at its upper end to the cylindrical sleeve member 5.
  • the sleeve member 5' is located in an opening, which is preferably circular, of the member I5 which may have any desired shape.
  • the member I 5 is mounted upon the upper end of the protecting tube I6 which is secured in any desired way to the socket member 1.
  • a washer member I1 At about the central portion of the protecting tube I6 for the torsion spring 2 there is provided a washer member I1 having a central aperture which assists in guiding the spring.
  • members 5 and 5' are capable of movement along the longitudinal axis of the projectile.
  • the sleeve member 5 may have such movement in the recess 6 provided in the socket member 1 while the sleeve member 5' is capable of such movement in the opening provided in the member I5.
  • the support for the sleeve member 5 consists of a shock absorbing spring I8 which is secured to the member I5 by rivets or any other desired securing means.
  • the spring I8 may be star shaped, for example, and is secured at its central portion to the sleeve member 5'.
  • any other desired type of resilient mounting for the sleeve member 5' may be utilized in order to permit the sleeve member 5' to have limited axial movement relative to its support extending between the bearing 20 and a bar 2
  • the axial play of the sleeve member 5 is preferably greater than that of thependulum I sot that upon ringthe torsion spring maybe completelyrelieved from the consequent shOCk. during the initial axial accelerationof theiDIOjCtile. f
  • shock absorbing means are formed by one or more springs of various types these means may also include or' comprise any resilient or elastic element which is suitable for and capable of accomplishing the functions of ⁇ a shols abserber. F01?, example, Such Shock absorbing effect may be obtained by mounting the protective tube I6 resiliently in an axial direction.
  • a regulating mechanism for the clockwork of a mechanical time fuse for projectiles comprising a pendulum, a torsion regulating spring located along.v the longitudinal axis of the projectile supporting said pendulum, a protecting tube eneirrfclinugv said spring, a support for said spring at its forward end, a shock reducing spring supporting Said, Support located: uson: the. forward end of saidprotecting tube, a coupling member connectingy the rear end offsaid regulating spring to the axis of said pendulum and said pendulum beine disposqdvfin, the bodyof said projectile with relatively Slight anal playj 2.
