Definitions

  • Single barreled multiple-shot, or repeating, Shotguns are known, wherein the expulsion of the cartridge which has been tired, the introduction into the tiring chamber of the cartridges to be fired, and the loading or cocking of the percussion elements, are effected automatically by the reaction of the gases (recoil) which causes the barrel to move backwards integrally with the loading and tiring mechanism.
  • Such Shotguns generally have the cartridge magazine in the initial section of the barrel and this leads to an unbalance of the weapon, because it is made heavier by the weight ofthe said cartridges at the front.
  • Another object of the present invention is to provide a device to feed the cartridges into the tiring chamber which will permit introduction of the cartridges into the magazine in a simple and reliable manner. 5
  • the automatic shotgun according to the present invention is characterised in that it comprises a cartridge magazine arranged on the triggerguard element and extended into the stock, and a lifter arranged at the end of the magazine and consisting in a sec- 50 tion pivoted to the casing of the shotgun and a section pivoted to the iirst section so that the two sections tilt in both directions to permit the introduction of the cartridge into the magazine and to carry the cartridge which is to be tired from time to time into the tiring chamber.
  • FIG. 1 is partial section of the lifter and the cartridge magazine with the lifter in the condition of manual introduction of the cartridges linto the magazine;
  • FIG. 2 is a section similar to FIGURE 1, but with the lifter in the cartridge locking condition;
  • FIG. 3 is a section similar to FIGURE l, but in the condition of housing a cartridge on the lifter;
  • FIG. 4 is a section similar to FIGURE l, but in the condition of positioning the cartridge in the barrel;
  • FIGS. 5 and 6 are perspective views of the lifter in two different conditions. F
  • an automatic shotgun is shown ICC having a barrel 1 integral with the breech 2 and which, when tiring has occurred, moves backwards with the latter and then returns into the normal position by means of a customary return spring. During the return movement, a fresh cartridge which is to be red enters the tiring chamber.
  • a bore 4 which is extended into the stock of the shotgun and in which there is inserted a metallic tube 5 which constitutes the cartridge magazine with a cup 6 slidable therein and urged towards the right-hand side of the drawing by a helical spring 7 inserted in the tube 5 between the cup and the closed end of the magazine.
  • the trigger-guard element 3 has a chamber 8 in front of the open end of the magazine, and opens downwardly to permit the introduction of the cartridges into the magazine.
  • a lifter generally designated at 9 (see FIGS. 5 and 6) and substantially consisting in two elements.
  • One element, designated 10, has a frontal plate 11 on the sides of which are fixed two arms 12 and 13 extending at right angles to the plate 11.
  • the plate 11 has at the rear two shoulders 14 and 15, one on each side, having in their upper portion two holes 22 disposed in mutual coaxial alignment intended to receive a pin 16 (FIG. l) of a positioner 17 inserted in a tube 18 provided in the hand-guard rod 19 of the shotgun and continuously urged by a helical spring 20 disposed in the tube 18.
  • the free ends of the two arms 12 and 13 each has a through hole 21 arranged coaxially aligned.
  • the arm 12 has on its upper edge a semi-circular recess 23, the purpose of which will be explained hereinbelow.
  • the other element, designated 24, is arcuate and has a cylindrical seat 25 suitable for housing a cartridge.
  • a projection 26 carrying an outwardly projecting stud 27 which is intended to be normally housed in the semi-circular recess 23 of the element 1i).
  • One end of the element 24 has a through hole (not shown in the figure) which serves to pivotally connect the said end to the free end of the arms 12 and 13 by means of a pin 28. In this way the element 10 is pivoted to the casing of the shotgun by means of the pin 16, whereas the element 24 is pivoted in the element 10 by the pin 28, and the two elements are thus pivotally movable in both directions.
  • FIGS. 1 4 are views of subsequent steps of the movement ofthe lifter.
  • FIG. l illustrates the position of the lifter 9 at the step of introducing the cartridge C manually into the attached magazine 5 which, as already stated, extends from the trigger-guard element 3 into the stock of the shotgun.
  • the lifter 9 By pressing the lifter 9 towards the breech block 29, the lifter permits entry of the cartridge C into the magazine 5.
  • the lifter 9 is automatically restored into the cartridge holding position by means of the positioner 17, which slides in the tube 18 and is urged continuously forward by the spring 20. This movement is repeated at each introduction of a cartridge until the magazine 5 is full.
  • FIG. 2 illustrates the position of the lifter 9 at the cartridge blocking step in the magazine 5, maintained by the positioner 17.
  • FIG. 3 illustrates the beginning of the step of loading the cartridge C into the barrel 1.
  • This movement of the lifter 9 occurs after the expulsion of the fired cartridge and after the recoil has occurred, with the return into position of the breech-barrel 2-1.
  • a suitable ⁇ ltasaasv' rotate downwardly about the pin 16, permitting the eartridge C, urged by the spring 7, to slide in the cylindrical seat 25 of the element 24 of the lifter 9 until it strikes against the plate 11.
  • FIG, 4 illustrates the final step for the leading ot the cartridge C into the barrel l. Whilst the cartridge C is travelling the final millimetres of its travel in the seat 25 of the element 24 of the lifter 9, it squeezes a lug (not shown) which releases a lever 30 which rotates by the action of a bias-tensioned spring of the breech block 29, and in its rotation the lever 30 displaces the element 24 of the elevator by means of the stud 27 upwardly about its pivot 28 and transports the cartridge C into the position of introduction into the barrel l. Upon movement of the lever 30, the breech block 29 is released and urges the cartridge into the barrel, returns, the lever 30 into the position of abutment, and terminates with the closure of the weapon.
  • a single barreled automatic shotgunsof the multipleshot or repeating type having a stock, a casing defining a tiring chamber supported on said stock, a trigger-guard mounted ou said stock adjacent said tiring chamber, and a cartridge-loading mechanism comprising a cartridge magazine having an open and a closed end disposed on the trigger-guard element with said closed end extending into the stock, and a lifter arranged at said open end of the magazine consisting in a first section pivoted adjacent one end to said casing and a second section pivoted to the opposite free end of said rst section such that said sections are operatively arranged for pivotal lifting movement effective to carry a cartridge placed on said second section into said firing chamber, said second section having a cylindrical surface forming a seat for said cartridge and a laterally projecting stud thereon which serves as a grip facilitating the raising of said sections through said pivotal lifting movement.
