Definitions

  • the rapidity of loading and firing is such that it may exceed that which can be normally attained in supplying cartridges or projectiles when there is used for the setting of the fuses of these latter a fuse setter with a single station.
  • the present invention relates to a fuse setter f progressive and continuous operation, the arrangement of which is such that it permits simultaneously the presence on the apparatus atthe same time of a plurality of projectiles to be set and a continuous supply and a continuous withdrawal of the cartridges or projectiles by the loading gunner, without the movements of these different men in any way interfering with one another.
  • each fuse can he proceeded with up to the instant when the projectile which carries the fuse in question is withdrawn from the fuse setter by the loading gunner.
  • the fuse setter in question comprises the combination with a base or bed plate element fixed and carrying the different setting control mechanisms. of a movable plate or drum comprising a certain number of stations or sockets, of ogive fuses of which are to be set, the said movable plate or drum being constituted and mounted in such manner and being connected to the setting control mechanisms in such manner that, owing to the periodical displacement imparted to this drum, each cartridge or projectile, after having been introduced into the socket which at the movement of the said introduction occupied a given position, is carried with the receptacle in question towards a final position of withdrawal and. undergoes during at least a portion of this journey a progressive and continuous preparation of the setting to be effected, the latter nevertheless preferably not becoming definite until the exact moment when the cartridge or the projectile in question is withdrawn by the loader.
  • the said fuse setter is furthermore characterized by the arrangement and the placing in operation of accessory devices of engagement and synchronization, due to which the setting 01' the fuses is made independent of the orientation of the projectile at the moment when it is placed in position on the setter, and owing to which the movable plate or drum of the latter is only displaced after the cartridge or the projectile which occupies the withdrawal position has been withdrawn from the socket which it occupied.
  • Figure 1 represents a perspective view of one embodiment of the invention which, by parts being broken away, permits the principle of the constitution and operation of the apparatus to be understood.
  • Figure 2 is a view in elevation and partial section of the line IIII of Figure 3 of a modified form of the invention, including automatic means for lockin the movable drum in stationary position as long as there is a projectile in thecompartment occupying the withdrawal position.
  • Figure 3 is a plan view with partial section on the line IIIIII of Figure. 2.
  • Figure 4 is a general diagram enabling the various stages of the operations to be followed.
  • Figures ,5 and 6 are diagrams of details showing the particular arrangement due to .which' 7 interior of which is arranged the setting control mechanism constituted by an endless screw 2 which is driven by means of an external crank not shown and which engages with a toothed sector 3, integral with a cylindrical sleeve 4 adapted, when it is driven by the toothed sector 3, to rotate freely about the axis X-X of the apparatus.
  • the setting control mechanism constituted by an endless screw 2 which is driven by means of an external crank not shown and which engages with a toothed sector 3, integral with a cylindrical sleeve 4 adapted, when it is driven by the toothed sector 3, to rotate freely about the axis X-X of the apparatus.
  • the said cylindrical sleeve ii is provided with a toothed control sector and a-guide cam collar 6, the purpose of which will be explained later.
  • a cylindrical plate or drum 3 comprising first of all at its upper part a certain number of internally serrated recesses or compartments 9l Ei-l il2 (four in the present case) of dimensions corresponding to the diameter of the munitions to be dealtwith, and then, on its inner face an equal number of hollow cylindrical supports l3-!4-l5-l8 in the interior of which are rotatably'mounted hollow cylindrical sockets ll-l8-l9-2fi, the upper ends of which are also internally serrated as indicated at 2
  • Each of these sockets has on its outer surface, at the level of the toothed control sector 5 of the sleeve 4, a corresponding set of teeth 22 and also, at its lower extremity at the level of and opposite the guide cam collar ⁇ 3 of the sleeve 5, a corresponding guiding and co-operating nose piece or projection 23 with a concave circular edge. 7
  • the supports l3ll-l5i5 are arranged in such manner that the axes of the sockets lll'8-lS-'2il coincide respectively with the axes of the recesses '9itll ll2, and so that each recess and its corresponding socket constitute a receptacle for the ogival, fuse carrying head of a projectile.
  • the movable drum 8 is provided on the outside with manipulating handles 2tl25- 26-27, preferably equal in number to that of the recesses and of locking devices constituted either according to what is shown on Figure 1, at 2829-353l, intended to receive the extremity 32 of a stop bolt 33, subjected to the action of a spring 35 and adapted to be controlled by means of a manipulating handle 35, or according to what is shown on Figure 2, by automatic devices, the details of which will be described later.
  • position a position 1
  • position 0 position d
  • the four successive positions which, by substitution, each recess and the corresponding socket successively occupy as the drum is caused to rotate, for example from the right towards the left.
  • the position a is what will be called the position of supply.
  • the position b is what will be called the intermediate position.
  • the position 0 is what will be called the withdrawal'or removal position.
  • the position (1 is What will be called the return position.
  • the teeth 25 of the upper edge of the said socket are directed in such manner as to coincide exactly with the teeth 36 of the corresponding recess of the drum 8, and the axis of symmetry m-n of the projection 23 is directed towards the centre 0 of the apparatus.
  • the fixed tenon and the movable tenon of the fuse may, without having to undergo relative displacement one with respect to the other, penetrate simultaneously and respectively:
  • toothed control sector 5 of the cylindrical sleeve t extends over only a portion of the periphery of the said sleeve, its length being strictly equivalent to that of the periphery of the sockets.
  • the dififerent directions which the said sector 5 takes up, owing to the action of the endless screw 2 on the toothed sector 3 of the sleeve 4, are such that in no case does the said toothed control sector 5 come into engage. lent with the teeth 22 of a socket when the latter is in the position a, that is to say, in the position of sup- P y.
  • the projectile In passing from the intermediate position b to the position of withdrawal 0, the projectile therefore undergoes automatically the influence of the setting control mechanism, which itself may also be placed simultaneously in movement for any desired modification of the said setting, as the two operations may be carried out in a mutual manner without interfering with each other.
  • a first indentation 38 suitably disposed on the guide cam collar 6, a first indentation 38 suitably disposed.
  • the socket Due to the said supplementary movement of rotation, the socket effects the complete rotation which it had commenced to make, and according to what is shown at e on Figure 4, its projection 23 is again brought into contact with the collar 6, the latter including a second indentation 45 to permit the passage of the heel 39 of the projection 23.
  • the fresh projectile is not put in at the return position d (or at any of the return positions at if there are more than one), but is only introduced at the supply position a.
  • the automatic device in question is formed by two telescopic sliding members 56 and 4'! subjected respectively:
  • the said track is entirely level over the whole of its length except opposite the withdrawal position 0.
  • the drum 8 may be set in movement up to the time when the projectile which was in the intermediate waiting position b moves into the position 0 and causes a fresh look-
