<p>P-330 AUXILIARY FIRING MECHANISM An auxiliary firing mechanism (26) used to actuate a tripper for a gun trigger includes a remote actuator (28) connected to the tripper by an elongated connector such as a cable (30) that is moved by the cooperable action of a control member (68) and a rotatably and axially movable actuator member (74) of the actuator. Camming surfaces (90,92) of the control member and the actuator member of the actuator move the control member from a first position to a second position against a spring bias (76) thereof in order to actuate the tripper and thereby trip the gun trigger whereupon the camming surface (92) of the actuator member moves out of engagement with the camming surface (90) of the control member in order to allow the control member to be moved back to the first position by its spring bias.. Axial and rotational movement of the actuator member then again engages the camming surfaces of the control and actuator members in preparation for another actuation of the tripper. A manually movable lever (94) which preferably has a foot pedal (96) rotates the actuator member to provide the tripper actuation,</p> |
