Definitions

  • the present invention relates to a device for simultaneously supplying with ammunition, such as cartridges, two guns associated for simultaneous training.
  • the device comprises for each gun two loaders, each for a complete round of ammunition and both arranged so that, by means of a single operating device, it is possible first to simultaneously actuate one of the loaders of each of the two guns, and then by bringing a movable coupling into a second position, to simultaneously actuate the other two loaders of the associated guns.
  • the elements of the double loaders of one of the guns are coupled with the elements of the second gun in such a manner that the manipulation of the loader of one of the guns facilitates and balances to a. certain extent the effort necessary for the manipulation of the associated loader of the other gun.
  • the device of the 20 present invention is described and shown in association with an ammunition supplying device of the character disclosed in U. S. Letters Patent Nos. 2,004,855 and 2,004,856, comprising a fixed ammunitionhoist and a swivelling, tiltable receiving apparatus in the firing chamber.
  • the novel device with two loaders and combined manipulating means accords the advantage of permitting two charges which are to be used successively to be supplied simultaneously to each 30 gun.
  • the time available for the supply of ammunition to the guns is twice as long as if there were only a single round of ammunition avail- 40 able at each gun at the time of each load.
  • the result of this is that such supply may be effected during the loading of the gun and the consecutive firing of the two available rounds, and that consequently the firing rhythm is limited solely by the time required for manipulating the loaders. for introducing the ammunition into the gun and for the firing operations. It will be appreciated that under these conditions the rapidity of firing may be considerably improved.

  • Figure 2 is a sectional view, with certain parts shown in full and others broken away, taken substantially on the line II--II of Figure 1;
  • Figure 3 is a longitudinal section, in elevation, taken substantially on the line III-III of Figure 4;
  • Figure 4 is a plan view, with certain parts shown in section, of the turret of Figures 1-3;
  • Figures 5 and 6 show the details of the mechanism for manipulating the loaders, Figure 5 being a cross section taken substantially on the line V-V of Figures 1 and 4, while Figure 6 is a longitudinal section through the pivoting axis of a loader; and
  • Figures 7 and 8 show the organization of the ammunition receiving apparatus at the top of the hoist, Figure 7 being a sectional elevation through the ammunition carriers and Figure 8 a corresponding plan View.
  • FIGs 1, 2, 3, and 4 the guns I are shown mounted in the known manner in the cradles 2, the latter resting by their trunnions 3 on mountings or cradle supports 4.
  • each gun comprises a horizontal wedge breechblock.
  • a recess 6 provided in the breechblock 1 ( Figure 3) allows the loader and ammunition transported from the waiting position at the side (shown in solid lines in Figure 2) to pass to the loading position behind the gun (shown in chain lines in Figure 2)
  • the head plates 4 of the gun mountings in the example shown are fixed to a rotatable platform 8 which is mounted on a fixed bearing 9 by means of a rolling and centering track.
  • the two cradles carrying the guns are connected for elevation with a single elevating shaft l0 ( Figure 2), from which, however, each of the guns may be disengaged, for example in case of damage, by means of the clutches I l.
  • the platform 8 may support a shield l2 forming a firing chamber and an operating floor I3.
  • the apparatus forming the ammunition supplying system is positioned along the vertical axis of rotation of the turret between the two guns, and comprises a fixed central hoist l4 and a device l5 for receiving the. ammunition at the top of the hoist.
  • the actual hoist M may be of a known type with a reciprocating hoisting mechanism. It comprises, however, according to the present form of construction of the invention, four tubes arranged symmetrically. In these four tubes, the four rounds of ammunition for the two guns are raised simultaneously.
  • This device comprises a kind of frame or support 56 adapted to pivot about its which rest on the frame it on a level corresponding with the trunnions 3 of the cradles 2.
  • Each of the carriers ll comprises a spring box 23, in which is movable a cap 2
  • the cap in being raised compresses a spring 20 which subsequently serves to expel the ammunition from the carrier and to ensure its introduction into the corresponding loader.
  • Mounted in the lower part of each carrier is a retractable pawl 22 rotatable on a pin 23 and constantly urged below the ammunition by a torsion spring 24.
  • the carriers ll and their braceframe 83 are tilted about the trunnions l9 so as to be brought into line with the gun loaders into which all of the rounds of ammunition in carriers I! are introduced simultaneously by automatic disengagement of the retractable pawls 22 and consequent operation of the springs 20.
  • the loader system comprises for each of the guns two loaders 25 and 25a. ( Figures 1 to 4) each in the form of a tube open along a wide lateral slit 26 for the passage of the apparatus for ramming the ammunition into the gun, which apparatus may be of any appropriate known rammer or take type.
  • the loaders 25 and 25a are supported by arms 21 secured to'shafts 28 and 28 arranged symmetrically above and below and pivotally mounted in the supports 5.
  • the positions of the shafts are determined so that each of the loaders may be brought either into line with the'associated gun for the introduction of the ammunition into the latter, or into a waiting position at the side for receiving the ammunition from carriers ll. In this waiting position, the loaders, are in contact with the stops 58, 59 ( Figures land 4) for ,the'upper loaders and 5G and 6! for the lower .whence theyareprojected by the springs 20'.
  • the waiting positions of the fourloaders are symmetrical relatively ,to' both the vertical axial plane of the turret and the axial plane common to the two guns, so that, for" receiving the ammunition, they are able to occupy positions in correspondence with the pairs of carriers I! of the device [5.
  • the shafts 28 and 28' of the upper and lower loaders are connected at their forward ends to a common transmission mechanism, a constructional example of which is shown in detail in Figures 5 and 6.
  • to shafts 28 and 28' and their associated loaders 25 and 25a comprises for each gun two transverse shafts 29 and 30 connected to the shafts 28 and 28, respectively, of the corresponding loaders by bevel pinions 3!, 32 and 33, 34, a vertical intermediate shaft 35 connected to the shafts 23 and 30 by the bevel pinions 36, 31 and 38, 39, a dog clutch slidably splineol on the shaft 29 so that it can be coupled with either of the pinions 3!
  • Movement of the clutch 4D is controlled by an arrangement comprising a forked lever 44 engaging a groove formed in the clutch and a rod 45 which is mounted for sliding movement parallel to shaft 29 and carries at its free end an operating handle 56.
  • the rod 45 also carries two projections 45, 4! adapted to engage notches 48, 49, respectively, provided in plates 3 l, 36 integral with the pinions 3! and 36.
  • one of the projections 454l enters the corresponding notch of the pinion which has just been declutched, while the other is withdrawn from the notch of the clutched pinion.
  • one of the loaders 25 or 25a is always mechanically connected to the clutch sleeve 40 and hence to the shaft 29 and the handwheel fil, while the other loader 25a. or 25 is locked by engagement of the projection 45 or 41 of the rod 45 in the notch of the pinion corresponding to the shaft 28 or 28 of the said loader.
  • the handwheel 5! comprises a spring handle 50 which, when the loaders are in the waiting position, engages by means of a nipple a fixed recess 51 provided in the support 5. The shaft 29 is thus locked while the manipulation of the clutch sleeve 43 is being effected.
  • the transmission mechanisms of the two guns are mounted symmetrically, as shown in Figure 5, relatively to the plane of symmetry of the movable platform or turret. Furthermore, these two transmission mechanisms are coupled in the space between the guns by means of sleeves 52, 53, for the shafts 25!, and a link 56 for the rods 45. Finally, the attachment of the forks M to the rods 35 (which attachment allows the necessary play by means of a slot or fork) is adapted so that the two sleeves are carried simultaneously either to the right or to the left, as the case may be.
  • loaders are thus mechanically connected to the shafts 29 and may consequently be manipulated at the same time so as to bring them from their waiting positions to their positions in line With the axes of the guns.
  • the two loaders thus simultaneously actuated are arranged symmetrically one in the upper part and the other in the lower part, it follows that, during the operation, these loaders balance each other, thereby very considerably reducing the expenditure of energy required, so much so that manipulation may be eifected by one attendant operating either of the handwheels 5 i, the hand- Lwheel which is not being used being uncoupled from its shaft 29 by withdrawing the cotter 55 from the corresponding segment 43.
  • This cotter may be attached to one end of a small chain, the other end of which will be attached to a fixed point, and on being disengaged from the shaft 29 may be inserted in a suitable recess (not shown).
  • the attendant In. order to effect loading of the guns, the attendant first operates handwheel 4! so as to bring two diagonally opposite loaders 25 or 25a into line with the axes of the guns, the rounds of ammunition being then rammed home into the guns by known means. Upon rotating the handwheel 4! in the opposite direction, the empty loaders are returned to their waiting positions. The attendant then displaces the sleeves M1 by acting on operating handle 55. He will thus be ready to ensure the operation of the other two loaders as soon as the guns have been fired and the vbreeches are opened again.
  • the invention makes available for the operations to be eifected with the ammunition supplying system, hoist and receiving apparatus at the top of the hoist, a period of time double that which would exist if only a single charge per gun were at hand at the time of each load.
  • a smoother and safer supply of ammunition can be attained with less man powerthan in known systems where each load must be separately handled from shell room to gun.
  • a driving shaft rotatably carried by each of said supporting members, means for rotating each of said loading members about its pivotal axis so as to move said member from its normal position to a loading position in line with the axis of the associated gun and return, means for selectively connecting the driving shaft of each gun with the rotating means of one or the other of the associated pair of loading members, and means for coupling said driving shafts together whereby the selected loading members of both guns may be actuated simultaneously.
