Definitions

  • the present invention relates to self-loading firearms th'ebreechb'lock of which'has a toand .fro longitudinal movement every time a round is fired and must, in order to be cocked, for instance in case of misfire, be pulled back against the action of an elastic system by means of a device operable by the gunner (the expression self-loading firearms including, in what follows, either semi-automatic firearms which are automatically reloaded but require a separate trigger pull for every round, or automatic firearms which fire bursts, or again-double operation firearms capable. of working either in semi-automatic or .in fully automatic fashion).
  • the chief objectof my invention is to'provide a firearm oi .thislkind which is better :adaptedto meettherequirements of practice than those used up to this time.
  • the oockingudevrice includes aesliding member guided longitudinally .in a casing mounted :adjacent to said breech block, said sliding member and said breech block including respective abutment parts adapted to bear against each other, when said sliding member is moved rearwardly with respect to said breech case, to drive said breech block rearwardly therewith.
  • At least one of said parts is adjustable with respect to the element (to wit either the sliding member or the breech block) to which it belongs, so as to make it possible to prevent said parts from cooperating with each other, whereby the firearm together with its breech block can be slipped frontwardly away from said cocking device.
  • Fig. l diagrammatically shows in horizontal section with parts removed and parts cut away, an automatic firearm mounted on a fixed support and fitted with a cocking device carried by said support, this structure being made according to my invention.
  • Fig. 2 shows the cocking device of this firearm in active position.
  • Fig. 3 is a sectional view on the line III--III of Fig. 2.
  • the firearm as a whole and with the exception of its cocking device, is, for instance, of the usual construction, including a breech block I mounted to recoil, against the action of a recuperator spring 2, in a breech case 3, itself mounted slidable on a fixed support S with the interposition of a butter 4 capable of absorbing the recoil energy and of returning the whole of the firearm into firing position.
  • the cocking device is mounted on support S and includes a casing 5 acting as a guide or slideway for a sliding piece 6 adapted to be pulled rearwardly by means of a cable 7, against the action of a return system consti- I participate in this backward movement.
  • one of the two abutment parts above mentioned must be made retractable or otherwise adjustable sot hat, when said projection is retracted or properly adjusted, the firearm can be removed from support S without requiring removal of its breech mechanism.
  • the arrangement is such that the-firearm can be disengaged without requiring a special operation to retract the catch '9.
  • said catch 9 is automatically retractedwhen sliding member 6 is in its front .end position and comes into active position, under the action of a return system, preferably at the beginning of the rearward movement of said sliding member and, anyway, before catch 9 reaches abutment part 1'0 (supposedto bein front end position).
  • catch *9 is pivotally mounted on sliding member :6 (about :a pivot axis 11) located near theifrontofisaidisliding member. Said catch :is :urged toward active position by areturln spring 12.
  • This cocking device works as follows:
  • a fixed support a firearm including a breech case, means for mounting said breech case in said support for removal therefrom only by sliding in a frontward direction with respect to said support, a breech block reciprocable longitudinally in said breech case and an abutment part rigid with said breech block and projecting transversely therefrom, and a cocking device including a casing rigid with said support and mounted adjacent to said breech case, a sliding element guided longitudinally in said casing, a catch carried by said sliding element so as to project transversely from said casing to engage said abutment part when said sliding element is moved rear- Wardly in said casing whereby said breech block is driven rearwardly by said sliding element moving rearwardly, means for movably mounting said catch on said sliding element for retraction at least partially into said sliding element transversely out of the path of travel of said abutment part, to make it possible to remove the firearm from said support by pulling it frontwardly, elastic means for urging said
