lower firing pin 50 has acoaxial actuation spring 502, which acts in contrast with a lowerfiring pin support 19 and with alower abutment 503 of the firing pin. - The
upper firing pin 5 has acoaxial actuation spring 52, which acts in contrast with an upperfiring pin support 20 and with anupper abutment 53 of the firing pin. - The
abutments re-cocking plate 21, which is arranged in front of the firing pins and on which acocking lever 22 acts. - The cocking
lever 22 is associated with alocking member 23 on which ahandle 24 acts which actuates the opening of the barrels. - The
locking member 23 is constituted by a vertical cylinder and includes a pair of holes, respectively alower hole 231, for the passage of thelower firing pin 50, and anupper hole 232, for the passage of theupper firing pin 5, when the firearm is in the position in which the barrels are closed. - The trigger assembly according to the present invention includes a trigger selector device which is constituted by a
rod 25 which has a lower end inserted in thefork 121 of the oscillatingmember 12 and an upper end associated with abutton 26. Thebutton 26 can move transversely in aslider 27, which in turn can move longitudinally in ablock 28 which is associated with the upper part of thebody 2. - The
button 26 allows to make the lower end of therod 25 oscillate so as to shift thefork 121, and therefore theoscillating member 12, to the right or to the left with respect to the central position, making thecentral tooth 123 match up alternately respectively with therear end 131 of thelower trigger lever 13, or therear end 141 of theupper trigger lever 14. -
Figures 2 and3 are views of the selector device in the triggering position of thelower firing pin 50. As can be seen inFigure 4 , in this position thecentral tooth 123 rests against theupper end 131 of thelower trigger lever 13. - The
slider 27 constitutes the member for actuating the firearm safety catch and can slide with respect to theblock 28 on thebody 2 between two positions: a firing position and a safety catch engaged position. - The
slider 27 is associated with anangled tab 29, with in the safety catch engaged position interferes with the rear ends of the trigger levers 13 and 14, preventing their movement, as can be seen inFigure 5 . - In the firing position, which corresponds to the slider in the forward position, visible in
Figure 6 , theangled tab 29 leaves the rear ends of the trigger levers free to rise and therefore actuate the firing pins, as will be explained hereinafter. - A
wire spring 30 interposed between theblock 28 and thebody 2 engages apivot 31 of theangled tab 29 so as to render the forward and retracted positions of the slider stable. - The trigger assembly can optionally include an automatic safety engagement system which acts when the barrels are opened by rotating the
handle 24. - The automatic safety catch engagement system is constituted by a safety
catch actuation bar 32 which has a rear end, associated with theangled tab 29, and a freefront end 321, on which acam 241 acts. - The
cam 241 is associated with thehandle 24 and, when the handle is turned, thecam 241 pushes thebar 32, making it retract, consequently shifting backward theslider 27, which reaches the engaged safety catch position, visible inFigures 2 and5 . - The operation of the interchangeable firing assembly according to the present invention is as follows.
- The
casing 2, which contains the complete trigger assembly, can be inserted and extracted through the lower gap of thebreak action 101, simply by acting on thecontrol button 4 of thesafety engagement device 3. - In the operating position, inserted within the break action and stably locked by the
engagement device 3, the trigger assembly is normally in the position in which the safety catch is engaged, visible inFigure 5 , in which theangled tab 29 interferes with the rear ends of the trigger levers 13 and 14, preventing their upward movement. - The safety catch is disengaged by making the
slider 27 slide forward, as visible inFigure 6 , which illustrates the firearm in a position ready for firing with the selector arranged in the position for firing the lower barrel. - The selector is actuated by means of the
button 26, which can be shifted to the right or to the left to select the barrel from which the first shot is to be fired. InFigures 2 ,5 and6 , the selector is shown in the position for firing the first shot on the lower barrel. - The first shot is fired by acting on the
trigger 6, which lifts, by means of therear tab 65, the oscillatingmember 12, thecentral tooth 123 of which engages therear end 131 of the lower trigger lever 13 (as visible inFigure 4 ). - The
lower trigger lever 13 acts on the lower firingpin trigger lever 17, lowering itsend part 171, which disengages thetooth 501 of thelower firing pin 50. - The
lower firing pin 50 snaps forward, due to thespring 502, and causes firing. - The above cited sequence is illustrated in
Figures 7 and8 , whileFigure 9 is a view of thelower firing pin 50 which has been triggered and of the stroke limit of thetrigger 6. -
Figure 10 is a view of the engagement position for the second shot. In this position, the selector is in the position for firing on the upper barrel, since the oscillatingmember 12 has engaged on the upper trigger lever (with reference toFigure 3 ) upon release of the trigger after firing the first shot, virtue of the presence of the lateralinclined plane 125, which has interacted with therear end 141 of theupper trigger lever 14. - In the position for engagement of the second shot, the
inclined plane 125, visible inFigure 4 , engages therear end 141 of theupper trigger lever 14, when thetrigger 6 is actuated again, as can be seen in the firing sequence shown inFigures 11-13 . - The firing sequence of the second shot is similar to the sequence of the first shot, except that of course it uses the mechanism of the upper firing pin, which is constituted by the
upper trigger lever 14, by the upper firingpin trigger lever 18 and by theupper firing pin 5. -
Figure 14 is a view of the assembly in the condition in which both firing pins have been triggered, before their re-cocking. - The re-cocking steps are shown in
Figures 15 and16 . The re-cocking of the firing pins is performed automatically by opening the firearm by rotating thehandle 24. - By acting on the
handle 24, the cockinglever 22 associated therewith is rotated. The cockinglever 22 acts on there-cocking plate 21, which is arranged in front of the firing pins, pushing them backward, with reference toFigures 15 and16 , until theteeth tabs -
Figure 15 is a view of the first step of the re-cocking of the firing pins by partial rotation of the handle, whileFigure 16 is a view of the handle fully rotated and of re-cocking completed. - If the system for automatic safety catch engagement is present, the safety catch is engaged automatically when the
handle 24 is rotated, opening the barrels, as described above. -
