ABSTRACT:
The indirect-firing apparatus includes a combustion chamber for a cartridge (62), a trigger for igniting the cartridge, a barrel, an inertia block in the barrel, an anchor guide (7) designed to receive an anchor, a shuttle (34) in the anchor guide (7) mounted for movement from an anchor loading position to a position for firing and driving of the anchor, mechanisms (63, 11, 46) for displacement of the shuttle from one position to the other, and a barrel holder (61) for concomitantly controlling the closure of the combustion chamber (3) and means for displacement of the shuttle (34). The mechanisms (63, 11, 46) for displacement of the shuttle (34) are arranged so as to drive the shuttle (34) beyond the firing position (25). Damping components (33, 38), when the shuttle (34) has reached its firing position (25), absorb the action of the displacement mechanisms (63, 11, 46).
