ABSTRACT:
A hair trigger for a rifle provided with a principal or normal trigger mechanism (A) and a hair or light trigger mechanism (B) for the firing pin (1) of the weapon, the said normal trigger mechanism (A) comprising a trigger lever (9) pivotally mounted on a pin (6) and capable of angular displacement with the trigger (5) and a trigger slide (10) which is guided vertically and designed to act together with the overlying cam profile (3-4) of a foot (2) attached to the firing pin (1), the said trigger lever (9) being displaced by a spring (11) towards the trigger slide (10) while the latter is displaced by a corresponding spring (15) towards the said foot (2), the said trigger lever (9) acting as a strut to hold the trigger slide (10) in a condition immobilizing the firing pin in the retracted cocked position, the said trigger lever (9) being capable of being displaced by the trigger slide (10) when the firing pin (1) is released to fire a projectile, wherein the light trigger mechanism (B) includes a small piston or hammer (16) which is pressed down by a compressible spring (17) and is designed to strike against a front arm (18) of the trigger (5), an auxiliary trigger lever (19) arresting the said small piston or hammer (16) in a position in which the corresponding compressible spring (17) is compressed, and an auxiliary trigger slide (20) designed to engage the said arm of the trigger (5) to immobilize the auxiliary trigger lever (19) in the condition in which it arrests the small piston or hammer (16) in the cocked position, the said small piston or hammer (16) being capable of being displaced into this position by movement of the trigger towards the small piston or hammer (16) and being capable of being released from the said position by a slight rearward movement of the trigger so that it is released from the said auxiliary trigger slide (20), the action of the said small piston or hammer on the arm (18) of the trigger causing the trigger lever (9) to move away from the trigger slide (10) in order to release the firing pin when this is held in the cocked position.
