Definitions

  • ABSTRACT A gun having two barrels and a single trigger with a selector device for determining the order in which the barrels are fired by the single trigger, the said selector device including a balance arrangement designed to avoid the possibility of the second barrel being acci' dentally fired as the gun recoils from the first shot and the selecting device shifts to engage the release catch for the firing mechanism of the other barrel.
  • the selector arrangement comprises a first elongate element which is pivotally associated with the trigger in such a way that it cannot move radially with respect to the trigger, such radial movement causing engagement with the selected release catch of the gun to effect firing of one of the barrels and being caused when the trigger is pulled, and a second elongate element pivotally mounted at one end on the stock and linked at the other end to the first elongate element in such a way that relative radial movement with respect to said pivots is permitted (thereby allowing movement about said pivots, and deliberate firing movement of said first elongate element by moving said trigger) but relative movement in orthogonal directions with respect to said radial direction are prevented or restricted.
  • the present invention relates to guns, and particularly to guns having two barrels, either one above the other, or side by side, with a single trigger and means for selecting the sequence in which the barrels are fired by the single trigger.
  • Known selecting arrangements for the firing sequence of the barrels comprise a device associated with the trigger and provided with a projection which engages the ends of the release catches which control the release of the hammers.
  • a lever controllable from the outside of the gun is used to position the device in a first or in a second position depending on which barrel is selected for the firing first.
  • the projection of the device engages with one or other of the said release catches in such a way as to raise the release catch of the hammer corresponding to the selected barrel when the trigger is operated.
  • the device is linked to the trigger so that it is moved thereby when the trigger is operated.
  • the device Upon the firing of the first barrel the device, which has a certain mass, recoils with the recoil of the gun and this charges an elastic biasing element which subsequently urges the device back towards the release catches in such a way that the projection on the device moves into an operative position with respect to the release catch which was not previously actuated.
  • the gun is thus set up for firing the other barrel.
  • the body of the selector device in two parts, a first part having the projection for engagement with the end of the release catch and being pivotally associated with the trigger, and a second part movable on the first part in the radial direction with respect to the pivot on the trigger, and having a greater mass than the mass of the first part.
  • the object of the present invention is to provide a selector device for the selection of the firing sequence in a double-barrelled gun with a single trigger, which makes it possible to eliminate the above mentioned danger of accidental discharge to which known types of selector are prone, and to allow maximum degree of safety even during the closure of the gun, particularly in guns in which the trigger release is of very light weight.
  • a gun of the type having two barrels and a single trigger, and means for selecting the order in which the barrels are fired by successive operations of the single trigger
  • the selector device comprising a first elongate element, means pivotally associating said first elongate element at one end thereof with said trigger, projections at the other end of said first elongate element, said projections being selectively engageable with release catches which control the firing of said barrels, a second elongate element, said second elongate element being substantially heavier than said first elongate element, means pivotally connecting said second elongate element at one end thereof to said stock of said gun so that said second elongate element can swing in a plane including the recoil direction along which the gun recoils when fired, coupling means interconnecting said other ends of said first and second elongate elements, said coupling means allowing relative movement of said other ends of said first and second elongate elements in a substantially radial
  • FIG. 1 is a lateral view partially in section of part of a gun having an arrangement for selection of the firing sequence and formed as an embodiment of this invention
  • FIG. 2 is an exploded perspective view of the structure of the selector device itself
  • FIG. 3 is a cross section taken on the line III-III of FIG. 1.
  • the release catch 4 is shown in the released position which it adopts after firing has taken place (or before the firing hammers are cocked), and the catch 5 is shown in the cocked position.
  • the trigger 3 has a part 3a in which there is formed a cylindrical cavity within which there is slidably mounted a small piston 7 which is biased by a spring 8 toward the butt of the gun.
  • the piston 7 carries a pivot pin 9 to which is connected one end 10a of a bar 10 which forms the said first elongate element of the selector device of this invention.
  • the upper part 10b of the bar 10 is provided with three moulded projections 11, 12 and 12a, the projections 12 and 12a being arranged one on either side of the projection 11 for engagement in a known manner, with the ends 4a or 5a of the release catches 4 and 5.
  • the upper part b of the bar 10 is also provided with a pin 13 which extends on both sides of the bar 10 and cooperates with the inside surfaces 14 ofa deep slot 19 formed in a relatively heavy head 16 which is formed at the end of a second bar 17 which constitute the second elongate element of the selector device of this invention.
  • the deep slot 19 has inwardly turned flanges or lips along the edge adjacent the bar 10 and further inwardly turned flanges or lips 21 on the upper edge thereof.
  • the lower end of the bar 17 is pivoted on pin 20 secured to a fixed part of the stock 1 of the gun.
  • the lower end of bar 17 also is slidably mounted on pin 24 lateral movement.
  • the lips 21 define a slot within which engages the end 22 of projection 23 the lateral position of which is controllable from outside the gun by a movable button 24 which is arranged to effect movement of the selector device in a direction transverse to the longitudinal axis of the gun so as to select the barrel to be fired first.
  • the projection 23 is held in place by a spring 25 which, in a manner known per se, provides two stable positions for the head 16 which is thus held in one position or the other, in dependence on which barrel is selected to fire the first shot.
  • the body 3a of the trigger has two projections 26 which carry a transverse pin 29 in respective holes 28.
  • the rear part of the end 10a of the bar 10 abuts the pin 29 as the bar 10 rotates about the pivot 9 thus causing the piston 7 to be moved against the action of the biasing spring 8, or causing the bar 10 to rotate when the piston 7 is moved by the biasing spring 8.
  • Selection of the barrel to be fired first is effected by longitudinally moving the button 24 which, by engagement of the end 22 of the projection 23 with the lips 21 which define an angled slot moves the body 16 to one side or the other.
  • the movement of the head 16 transmits lateral movement, with respect to the longitudinal axis of the gun, in a direction perpendicular to both the recoil direction (which is parallel to the longitudinal axis of the gun), and the radial direction from the pivot 9, to the upper end 10b of the bar 10.
  • This movement is due to the engagement of the ends of the pin 13 with the side walls of the slot 19 which forms a rigid coupling with negligible play between the end 10b and the body 16 with respect to such lateral movement.
  • the projection 12 is placed in engagement with the end 4a or 5a of one of the release catches 4 or 5, assuming both catches 4 and 5 are cocked.
  • the projection 11 is engaged with the end 5a of the catch 5 so that the first barrel to be fired will be the one associated with the catch 5.
  • the selection of the first shot may be made by moving the button 24 in the opposite direction from that described above so that the catch 4 is released first rather than the catch 5.
  • the selector device is not in practice sensitive to the forces which might accidentally arise to cause the head 16 to move in a substantially radial direction with respect to the pivoting points 9 and 20 since the head 16 which constitutes the mass which is sensitive to the recoil action, is radially fixed with respect to the pivot 20 on the stock 1 of the gun so that radially directed forces with respect to the pivot 20, which arise, for example, when the gun is being closed, do not cause upward displacement of the head 16.
  • the bar 10 which is directly engaged with the ends 4a and 5a of the release catches, has relatively little mass so that although it is associated with the trigger and can be raised to operate the release catches, its mass is insufficient to cause accidental firing when the gun is being closed, and this is true even for guns having a very light weight trigger release. At the same time the maximum use of the recoil is made.
  • said means for selecting the order in which said barrels are fired by said trigger comprises:
  • interconnecting said first and second elongate elements comprise,
  • coupling means interconnecting said other ends of said first and second elongate elements, said coupling means allowing relative movement of said other ends of said first and second elongate elements with respect to each other in a substantially radial direction with respect to said pivots, and coupling said other ends together for movement in said recoil direction and in the direction perpendicular to both said substantially radial direction and said recoil direction.
