Definitions

  • This invention relates to gun loading apparatus of the type including a revolving magazine having a plurality of circumferentially-spaced longitudinally-extending magazine chambers each adapted to receive a round of ammunition therein, which magazine is rotatable in steps so as to bring any one of the chambers to a predetermined position, at which the round located in said chamber can be fired from a gun.
  • the rounds of ammunition are inserted into 'the magazine chambers shellor ogee-end foremost, and-the magazine chambers are so dimensioned, transversely, as to receive the shell section and a major part of the Cartridge section of each round with a narrow fit therein, while the rim, flange or bead provided at the rearmost end of the cartridge of the round would, on insertion of the round shell-end foremost, abut against a rear outer surface of the magazine without entering the chamber.
  • each magazine chamber in succession on rotation of the magazine, is brought to a firing position in axial alignment with the rear end of the gun bore, and the round is then fired, with the Cartridge remaining in the magazine chamber and being thereafter ejected therefrom.
  • each magazine chamber in succession constitutes, in effect, part of the gun bore.
  • each magazine chamber in turn forms a part of the gun bore necessarily introduces a discontinuity in the over-all cylindrcal bore surface at the point where the movable magazine chamber connects with the main or stationary gun struc- ⁇ tui-e.
  • Such discontinuity is objectionable since it set a limit to firing accuracy, amoung other reasons.
  • the ammunition has to be introduced into the magazine chambers from the rear end of the magazine, i.e. the end thereof remote from the gun muzzle. This considerably increases the over-all length dimension required for manning the gun; in many cases the 'available space behind a gun is severely limited.
  • a consequent object i ⁇ s to reduce the over-all length required to install and man a piece of artillery of given size, and to reduce the clearance required rearward of the piece.
  • a further object is to provide improved gun loading apparatus of the revolving-magazne type in which the i rounds of ammunition are not fired directly from the magazine chambers, but are extracted therefrom and rammed into the gun bore prior to firing; consequent objects are therefore to eliminate the discontinuity in the cylindrcal bore surface which was introduced by prior revolving-magazine loaders as eXplained above, and correspondingly to increase firing accuracy.
  • a broad object is the provision of a gun-loading system having improved performance from the standponts of speed, automatic operation, reliability, precision and Operating convenience.
  • gun loading apparatus comprising a revolving magazine having a plurality of magazine chambers each adapted to receive a round of ammunition, said chambers being transve'sely so dimensioned that the rounds are insertable into the chambers Cartridge-end foremost, and locking means associated with the magazine for looking said rounds against displacement once inserted into the chambers.
  • gun loading apparatus comprising a revolving magazine rotatable about an axis generally parallel to the bore of a gun tobe loaded and spaced laterally toone side therefrom and spaced axially beyond the rear end of the guri bore; a plurality of magazine chambers in said magazine adapted for receiving respective rounds of ammunition inserted thereinto from the ends of said chambers directed towards the gun muzzle Cartridge-end foremost and means for locking the rounds of ammunition against displacement in their respective chambers; means for imparting step rotation to the magazine to bring any one of said chambers to an extracting position adjacent the geometric axis of the gun bore; extractor means engageable with a round in extracting position for extracting it laterally out of the magazine into alignment with said bore axis; and rammer means engageable with a round when aligned with said aXis for ramming the round into the gun bore.
