  • a fuse setter body in which is disposed a sleeve-box, one rotatable part of which is adapted to engage the movable ring and is displaced by a gun server so as to rotate the said ring until the sleeve-box encounters a stop which is moved by a second gun serves as a function of the setting to be obtained.
  • the setting stop being formed by a member moving within the body of the fuse setter.
  • the manipulation of this fuse setter like that of other similar setting devices comprising an angular displacement of the movable time ring produced by pushing the projectile into the body of the fuse setter, requires the application of considerable force, since the movable time ring must ofier a suitable resistance to displacement, for if the friction to be overcome in moving the movable time ring were reduced there would be a danger of the set-ting being accidentally changed.
  • the present invention relates to a fuse setter comprising, in the known manner and for producing the angular displacement of the movable time ring, a fuse setter body in which is mounted a sleeve-box, one rotatable part of which, within which the said ring engages,
  • the setting device presents the feature that it permits the sleeve to be rotated by means of an efiective force applied to this sleeve which is much greater for the same effort exerted by the gun server who performs this operation.
  • the body of the fuse setter is, according to the invention, pivotedabout a shaft turning upon the gun carriage, upon a wagon or any other suitable support to which is secured a toothed sector.
  • the pivotal movement of the fuse setter body which the gun server can obtain by acting upon the projectile near the end of the latter or the placed in the known manner through the medium of a drive controlled by the range indicating device.

  • a supportC is secured a toothed sector with which engages a toothed crown g earned by a rotatable element G of the sleeve-box which the body A of the fuse setting device comprises.
  • the body A of the setting device comprises a projection a adapted to make contact with a stop it which isforrned upon a toothed sector H loosely mounted upon the fixed pivot B.
  • the movable element Gr of the sleeve-box is, as in the device forming the subject of prior U. S. Patent No. 1,680,902 provided with a crown Ihaving teeth 2' (Figs. 3, 6 and 7 for engagement with the lug j on the movable time ring J of the fuse, while the fixed element A of the sleeve box comprises forwardly projecting teeth a for engagementwith the fixed lug j of the fuse.
  • the projecting lugs j and j have, as shown in Fig. 7, the form of a trapezium with its larger base on the outside and engage easily between the corresponding teeth 2' and a the gaps between the latter be ing of corresponding trapezoidal shape.
  • the stop carrying sector 'HH is arranged for control as a function of the setting to be obtained by means'of a screw K which receives its movement through a suitable transmission gear from a range indicating device L, of any known type.
  • the projectile is slipped into the body of the setting device in such a way as to engage the lugs j and j between the teeth a and i of the sleeve-box respectively, this engagement being obtained with the greatest ease on account of the shape of the lugs and corresponding teeth.
  • This inward movement produces a pressure upon; the locking bolt MM and causes the latter to become disengaged.
  • the gun server removes the projectile from the setting device and can then load it immediately'into the gun.
  • the position corresponding to the greatest range can only makethe setting device approach the vertical, the latter, assoon as it is free is in the greater number of cases returned into'its initialposition under the action of its own weight, this return movement being moreover suitably damped, for example by means of the device shown in Fig. 1.
  • This device may comprise, as shown in the figure a hollow piston N pivoted to a tail piece'a on thebody'A of'the setting device and moving in a cylinder 0 j ournalled upon a fixed part such as the gun carriage' At the bottom of the cylinder is secured a tapering counter-rod P engaged in the-hollow piston N through'a diaphragm n.

  • a spring Q is disposed in the hollow piston, one end of this spring being connected at g to the counter-rod and the other end of the spring being free and situated at a convenient distance from the diaphragm a when the setting-device 1 spring Q is encountered by thediaphragm so that the said spring is compressed during all that part of the travel of the setting device comprised between the vertical and a suitably chosen inclination.
  • the setting device is mounted upon an ammunition wagon E.
  • the support C pivoted at C to the wagon is formed on the one hand the pivot B for the pivotal connection of the body of the setting device and of the stop carrying sector H h; this support carries as in the previous example the sector F cover which travels the movable element- G of the sleeve-box.
  • the range indicating device L Upon the same support is mounted the range indicating device L and also the transmission gear between the latter and the stop carrying sector; the whole of this arrangement is adapted to be lowered into the interior of the wagon E for travelling by means of the pivotal connection provided at C
  • the support C may be hooked by means of a rod R upon a catch mounted upon a lug E on the wagon as shown in Figs. 8 and 9.
  • the rotation of the movable time ring may as in the previous example be limited by itsencounter with the top 71/; but a setting operation may also be effected by causing the movable time ring to be rotated by a displacement of the stop.
  • the projectile may for setting purposes be moved in one direction or the other.
  • the projectile may be moved in the various positions by moving it in a clockwise direction for increasing ranges.
  • the fuse may also be set at will for a greater range or a smaller range, starting from an intermediate position, by moving the projectile in a clockwise direction or in an anti-clockwise direction without having to bring the setting device into the initial starting position.
