Definitions

  • This invention relates to a firing mechanism for shotguns, normally known as a breech block, constructed on the basis of a frame which houses the said firing mechanism proper within it, and a trigger plate on which the said firing device is mounted, comprising a single block assembly which can be easily attached to the stock of the gun and detached therefrom.
  • the mechanism according to the invention has been specially designed for shotguns with two parallel barrels, those commonly known as side-by-side shotguns, and the purpose of the invention is to provide maximum ease and speed in the work of fitting and dismantling the firing mechanism, together with optimum fitting and stability thereof in the operating or fitted condition.
  • shotguns provided with a firing block comprising a trigger plate which is fixed to the guard protecting the trigger and on which the breech block rocker, the left hand and right hand hammers, the left hand and right hand cocking levers, the rocker for each hammer, the rocker for each trigger and a counterweight are mounted, this assembly being housed within a frame which is conveniently attached to the trigger plate.
  • This assembly comprising the breech block is in turn intended to be housed within the stock of the shotgun in such a way that the trigger plate is coplanar with the lower surface of the stock, from which the trigger guard emerges, the said assembly being conveniently fixed to the stock of the shotgun, with the possibility of being dismantled.
  • One of the normal arrangements in the scope of side-by-side shotguns consists of providing each of the end portions of the trigger plate which project beyond the firing mechanism with openings for the passage of corresponding screws or bolts which tap into the stock of the shotgun in such a way that the trigger block can be removed from the latter by removing the said screws.
  • This arrangement gives rise to a problem which has two aspects, on the one hand the relative difficulty involved in removal and replacement of the said screws, which requires the use of an appropriate tool, which on many occasions is not available when necessary, and on the other hand the erosion which takes place in the stock of the shotgun at the point where the said screws are located when dismantling of the trigger block takes place a considerable number of times, which can lead to play and lack of adjustment in the firing mechanism.
  • the firing mechanism proposed by the invention intended as stated above for side-by-side shotguns, provides a fully satisfactory solution to the problems stated above.
  • the features of the said mechanism are based on the fact that the trigger plate on which the said operating components of the firing mechanism are mounted, and the frame making up the breech block, incorporates at one of its ends, preferably at its forward end, a latch which is intended to engage a mortise constructed in the stock of the gun, specifically at the front end of the housing in the said stock which receives the trigger block, while at the other end of the trigger plate there is incorporated a catch which can be retracted against the tension of a spring which acts as a member locking the trigger plate in another mortise constructed in the stock of the gun, into which it slidably engages, i.e.
  • the trigger block is fitted by engaging the trigger plate by one of its ends and then by applying frontal pressure from the latter on its opposite end, while for dismantling it is sufficient to pull the trigger guard gently while at the same time pressing the safety button which retracts the lock on the trigger plate.
  • the firing mechanism proposed by the invention which is intended for double barrelled shotguns or side-by-side shotguns, comprises, in the conventional way, on the basis of a trigger plate (1) to which is attached the trigger guard (2) for the trigger (3) and on which are fitted the rocker (4) of the breech block, the left hand (5) and right hand (6) hammers, the left hand (7) and right hand (8) cocking levers, the hammer rocker (9), the spring (10), the top cap (11) for the said spring, the rocker (12) of the trigger and the counterweight (13), while the structure and arrangement of these components can vary without affecting the essence of the invention which, as already mentioned, is centred on the means whereby this assembly, specifically the trigger plate (1) is attached to the stock of the gun.
  • trigger plate (1) incorporates at its forward end a latch (14), which in the embodiment illustrated in the figures is provided by a lower step in the said trigger plate and adopts a half-moon configuration, while obviously it may adopt any other configuration, this latch (14) obviously being intended to engage a complementary step in the stock of the gun, specifically in the step (14') of the frame (15) illustrated in Figures 4 and 5 which is intended to be secured in the said housing of the gun and receive the trigger plate (1) bearing the said firing mechanism proper, trigger plate (1), at its end opposite the said latch (14), where it is considerably recessed, incorporating as a supplementary means of attachment a locking catch (16) which emerges laterally from trigger plate (1) and which has a preferably curved/convex bevelled front, as may be seen especially in Figure 3, to encourage its coupling with a receiving mortise in the body of the gun, and more specifically the frame (15) located in the said mortise, by merely pressing the trigger plate (1) with its various accessories against the said stock.
  • latch (14) which in the
  • This locking catch (16) can be retracted against a spring (17) which projects against catch (16) at all times and is in turn affected by a transverse hole in which there is housed a gudgeon (18) which is secured to catch (16) with the help of an engaged screw (19) housed axially within the said spring (17) and which can be adjusted from the exterior through a small lateral hole (20) in the trigger plate, this gudgeon or bolt (18) being integral with a shoe (2) which engages a mortise (22) in the trigger plate and is in turn associated with an operating button (23) which emerges externally through the base or underside of the trigger plate so that it can be operated.
  • this release button (23) for the firing mechanism as a whole is protected by a posterior extension (24) of the trigger guard (2) for the trigger (3) in such a way that it is virtually impossible to accidentally or involuntarily operate it, possibly causing release of the mechanism, it being necessary in order to achieve this to have the assistance of a small auxiliary key (25), as shown in Figure 3, in order to bring about the necessary lateral displacement of button (23) which will cause locking catch (16) to be retracted against spring (17).
  • Figures 6 to 12 show in great detail the structure of trigger plate (1), both in respect of the forms of attachment of the various components of the firing mechanism proper, which are conventional, and in respect of its own and novel means of attachment to the stock of the gun, while Figures 13 to 15 show the right hand cocking lever and Figures 16 to 18 show the left hand cocking lever, which, as can be seen from the said figures, are substantially larger than normal, the opening (25) for their rocking axis being maintained in the central zone, incorporating at their distal end a laterally matched side piece (26) and at their other end, the proximal end, a bevel (27) so as to open a recess having a curved/concave base (28) affecting half the thickness of the cocking lever, the left hand cocking lever (7) being substantially symmetrical with respect to the right hand cocking lever (8), to which it is laterally adjacent in the mounting of the two cocking levers on the trigger plate (1).
