Definitions

  • 'lhis invention relates to cartridge cases for ⁇ V y towards the mouth or discharge opening of the firearms and ymore particularly to acartridge case which is provided with spring pressed d feeder blocks one on each sideof a dividing Wall, which 5 'blocks feed the rcartridges in double rows towards a constricted mouth'vof the case through which they are delivered one at a time.
  • acartridge case which is provided with spring pressed d feeder blocks one on each sideof a dividing Wall, which 5 'blocks feed the rcartridges in double rows towards a constricted mouth'vof the case through which they are delivered one at a time.
  • each cartridge feeder block is of a form to support two cartridges upon different levels and to move upwardly in the magazine in which it has'v movement;
  • the walls of the case and the dividing wall, forming two parallel magazines, guide 'the feeder blocksdn this movement of the blocks 'I'he side walls ofthe case 1 converge towards each other from a. point below the top of the dividing wall and are spaced apart to form an open mouth for the delivery of the cartridge -to the firearm.
  • Each converging por- .tion has a pocket formed therein for the reception of a part of the feeder block, said pockets .being closed at the top to limit feeding movement of the block and being of different lengths to permit greater movement of one of the blocks as compared with the other. This permits the successiveV delivery of the last few cartridges from bothmagazines in a single line of cartridges.
  • the upper part of the case is so formed that the four rows of cartridges in the two magazines suc-- cessively merge into one row atthe mouth.
  • Figs. 1 and 2 show vertical sections of a cartridge case made in ac- 45 cordance with the invention and Fig. 3 is a sec- -qssprlng I 0 acts to move the block and the two staggered rows Aof cartridges supported thereby case.
  • Each feeder block is provided with a forked y top having a long arm il or I 2 positioned adjacent the dividing wall 2, and a short arm 5 or 6 adz 5- jacent a side wall of the case.
  • the end walls of the case, as shown in Fig. 3, are ⁇ parallelthrough out, but the side walls converge adjacent the upf per part'of the case, and areV spaced apart'to forms.,
  • the dividing wall i0 i 2 terminates belowfthe'top of the case and the mouth or discharge'opening, but extends yabover the point ofv initial convergence of the side Walls. Below the converging side walls of the case, two i rows of cartridges are supported bythefeeder vlil block in each magazine, the cartridges in one row being staggered in relation to those in the other row. Between this point and the top of the Wall] 2, only one row of cartridges is'in each magazine,
  • Each converging side wall has a pocket 8v or 9 formed outwardly thereof, of la capacity to receive one fork 5 or 6 of the feeder block, but Inot wide enough to permit a cartridge to enter same, thus compelling each cartridge to follow the wall (see Fig. 1).
  • One of these pockets, as 9, is shorter l than and terminates below the otherpocket, as 8f'
  • the pocket 8 extends to closely adjacent mouth or discharge opening of the case.
  • one of the feeder blocks has its upward movement arrested when the last cartridgein-the magazine has passed the top of the wall 2, while the feeder blockin the. other magazine is permitted toV pass above the said wall untilall of the cartridges in both magazines have been drawn to a position where the t last one may be fed into the barrel of the firearm. or with the long arm of the forked end projecting through the mouth or discharge opening.
  • the long arm of one of the feeder blocks as 3, ris bevelled, so that with tilting movement ofk this block as a result of the engagement of the short arm 5 with the closed end of the pocketV 1, the'long arm will form a continuation of the wa1l2 and offer no obstruction to movement of cartridges by the other feeder block 4.
  • Both pockets yI and 8 have closed tops, and the upper portions thereof are so inclined as to be substantially parallel with the converging side wallsl of the case. 50
  • the two parallel magazines formed by the side walls of the case and the partition or ,dividingY wall 2 are each filled with cartridges, those in one 55 Both springs I are under compression.
  • one of the feeder blocks will first be raised by its spring and thus advance both rows of cartridges resting thereon toward the mouth or outlet. With the movement of the next cartridge, the otherfeeder block will be similarly actuated. As the outer cartridge in either magazine engages the converging side wall above.
  • the cartridge of the adjacent row will be forced upwardlyl in advance of that cartridge, as shown in Fig. 1, so as to' form a single row of cartridges within the constricted'portion adjacent the mouth or dischargeopening above each magazine.
  • the same action will occur above the wall 2 so as to form a single row of cartridges substantially centrally of the case below the mouth or dischargeopening.
  • the feeder blocks reachthe converging ,-upward movement of both blocks.
