Definitions

  • the present invention relates to an extremely compact, preferably gun-mounted, magazine for fully automatic artillery pieces, primarily anti-aircraft guns.
  • the magazine according to the present invention comprises a plurality of preferably vertical compartments for rounds of ammunition, the compartments being disposed in side-by-side parallel relationship and each accomodating a number of parallel superposed rounds, which may progressively be fed down to a discharge position specific to each compartment, whence the rounds are fed further towards the ramming position of the gun by means of a transverse feeding system common to all compartments by the intermediary of a transverse feeding channel which coincides with the mutually parallel discharge positions for all compartments, and the transverse feeding channel being, when the gun is fired, successively fed with new rounds at the same rate as rounds are fed into the gun, from that compartment which lies most distal from the ramming position of the gun and which has not yet been emptied.
  • a distinct advantage inherent in the magazine according to the present invention is that it may, since the discharge positions for the different round compartments coincide with the transverse feeding channel, be directly loaded right up to the ramming position of the gun without a successive and time- consuming stepwise feeding of the rounds for successive replenishment of a separate feeding channel.
  • This latter situation is, otherwise, the normal arrangement in gun magazines for large quantities of rounds. These are, moreover, often placed in the gun mounting instead of directly on the piece.
  • the gun-mounted magazines seldom accomodate more than from 10 to 20 rounds.
  • the magazine according to the present invention can, because it may be made so compact, be built for 100 rounds and more even in calibres of from 40-57 mm.
  • the previously-mentioned simultaneous loading of the compartments and transverse feeding channel is effected in that the compartments are filled and the transverse feeding channel is also automatically filled.
  • all compartments are provided with round hoists which are activated once the compartments have been filled. The round hoists then lift all rounds apart from the first in each compartment so that there is created a free channel between the first rounds located in the transverse feeding channel and remaining rounds.
  • a sensor is disposed on a level with each compartment which, as soon as it is ascertained that no round is located in its section of the transverse feeding channel, activates the round hoist in the next compartment in the direction of feed so that the rounds located in this compartment are given free passage to the transverse feeding channel.
  • the most distal compartment which, thus, is always to commence feeding rounds, has no round hoist. As a result of this arrangement, compartment after compartment will be successively emptied into the transverse feeding channel.
  • the anti-aircraft gun 1 illustrated in Fig. 1 is provided with two gun-mounted magazines 2 and 3 respectively.
  • a vertical gun feed channel 4 is disposed between the round magazines and may receive rounds from either one of the magazines 2 or 3 and feed these into the ramming position of the gun.
  • the magazines may be filled with different types of ammunition and the choice of magazine may be directly related to the target in question by means of separate command devices.
  • the magazines are provided with opening lids for replenishment with new rounds from above.
  • the lid 5 on the magazine 2 is shown in the half-open position.
  • the round magazine 2 illustrated in section in Fig. 2 comprises six compartments I-VI containing a total of 54 rounds numbered in the sequence they are fed towards the gun. Rounds numbers 1 and 2 are missing from the number series in the figure, since these rounds are loaded direct in the gun feeding channel 4.
  • the different compartments I-IV each have their discharge position which together form the transverse feeding channel 6 of the magazine. Rounds 3-8 are located in this transverse feeding channel.
  • a transverse feeding device 7 of the stepwise advancement type runs along the bottom of the transverse feeding channel 6. This will not be discussed in detail in the body of this disclosure and on the Drawings, since it does not, in actual fact, form part of the present invention. Its construction may also be designed in a number of different ways. Its general function is based on the circumstance that, for each round discharged by the gun, it advances the rounds located in the feeding channel 6 one step nearer and into the feed channel 4 of the gun.
  • each respective compartment is filled with at least one round so that all discharge positions along the transverse feeding channel 6 are filled.
  • these round hoists 8 When the compartments are filled, these round hoists 8 must be in the disengaged position, i.e. they must leave the compartments completely free so that these may be filled completely right down even to each respective discharge position.
  • Each compartment is further provided with a vertical feeder which guarantees uninterrupted feeding of the rounds along each respective compartment irrespective of the elevation of the gun.
  • the vertical feeders are not shown on the Drawings since they do not form part of the present invention and are, moreover, of conventional construction.
  • the vertical feeders may, for example, consist of hydraulically or spring-loaded feeding arms which act upon the uppermost round in each compartment.
  • rounds numbers 1 and 2 are placed in the gun feeding channel 4, whereafter the vertical feeders are activated.
  • the lid 5 of the magazine is closed.
  • the lid is either directly interconnected with a special operating function or this function is activated separately.
  • the round hoists 8 which, when the compartments were filled were in the disengaged position -are moved to the position illustrated in Figs. 2 and 4 where they lift all rounds in each compartment, apart from the rounds located in the discharge positions, a height sufficient to form a free channel between the rounds located along the transverse feeding channel 6 and the remaining rounds in the compartments.
  • compartment I has no round hoist. Hence, the rounds in this compartment enjoy free access to the discharge position of the compartment.
  • the rounds are, thus, fed by the transverse feeder 7 successively along the transverse feeding channel 6 in the direction of the arrow b at the same time as the transverse feeding channel is replenished with fresh rounds, starting with compartment I.
  • All compartments apart from compartment VI are, furthermore, provided with sensors generally designated 9 (see Fig. 4 and Figs. 6a and 6b).
  • the sensors for the emptied compartment trigger the round hoist in the subsequent compartment, seen in the feeding direction, which, thus, assumes the role of supplying new rounds to the transverse feeding channel.
  • the sensors 9 are placed in the bottom of the transverse feeding channel 6 where they are acted upon by the rounds advanced along this channel.
  • the more detailed function of the sensors 9 will be discussed in depth below, together with other mechanical arrangements according to the present invention. However, the invention should not be considered as restricted to those arrangements and solutions illustrated on the Drawings. These are rather to be considered as exemplifying preferred embodiments.
  • the function of the round hoists 8 and the sensors 9 will primarily be apparent from Figs. 4-6.
  • This operating function may, for example, consist of a number of linkage arms which are interconnected with one another and with the lid, for example as follows.
  • the lid 5 shifts a first link 10 from the position 10a to 10b and the arm 11 is thereby depressed the same distance about its shaft 15.
  • a lock 12 and a spring buffer 13 are disposed on the arm 11.
  • the lock 12 entrains the arm 14.
  • a fixed arrest 16 triggers the spring buffer 13 which, in its turn, triggers the lock 12 which releases its grip in the arm 14 which thereupon returns to its initial position under the action of a return buffer 17 disposed further ahead in the coupling chain.
  • the arm 14 has a rear overhang 18 at which a link 19 is fixedly anchored.
  • the link 19 is shifted in the direction of the arrow and, in its turn, shifts the links 20-24 in the direction of the arrows.
  • the links 20, 21 and 22 are fixedly mounted on the same shaft and pivot as a unit.
  • the link 24 is fixedly mounted on the same shaft as the link 25 in Figs. 5a and b.
  • the link 25 is interconnected with the links 26 and 27.
  • the angled arm 28 When the linkage system 24-27 is activated in the direction of the arrows, the angled arm 28 is shifted at the same time and, in its turn, acts upon the link 29 which in turn acts on a cranked link 30 which is journalled about a shaft 31 and is pivotally connected with the link 29 at its one arm 32 and with a second cranked link 34 at its other arm 33.
  • the second cranked link 34 is, in its turn, connected, at its other end, to the pivot arm 33 which is fixedly retained on the same shaft as the previously-mentioned round hoist 8.
  • the sensing arm 9 When the sensing arm 9 is no longer loaded by a round, in other words when the compartment has been emptied, the sensing arm shifts the link 37 in the direction of the arrow. On this movement, a compartment release block 38 is shifted from the first position beyond the toggle mechanism 3 1 -33-34 to a second position where the compartment release block 38 bridges the distance between the tripping point of the toggle mechanism, i.e. the point which trips the lock if it is actuated in the right direction, and a tripping abutment 39 (only included on Figs. 6a and 6b) which is interactive with the gun recoil and, for each discharge recoil, passes the above-mentioned point but itself does not reach the critical point on the toggle mechanism.
  • the round hoist 8 will be released on the first recoil once the compartment release block 38 has been shifted to its second position.
  • the round hoist 8 may be provided with a release spring (35, not shown on the Drawings) which actuates the round hoist 8 in the release direction.
  • the round hoists in all compartments function in the above-described manner and the system thus guarantees a reliable feed function until all compartments have been emptied.
