ABSTRACT:
A trigger mechanism for a shotgun with superposed barrels provides certainty in the firing of the second shot from the upper barrel after firing of the first shot from the lower barrel. The trigger mechanism includes a cam engaging the sear for the upper trigger and having an inverted L-shaped opening and a arcuate slot. The cam is biased by the hammer for the lower barrel into a position in which the pins prevent movement of the cam and release of the upper hammer sear. Upon release of the trigger following the firing of the first shot from the lower barrel, a spring biases the cam into a position in which it can be moved by a subsequent action of the trigger to actuate the upper sear to release the hammer for the upper barrel and fire the second shot. The cocking nose of each sear has a circular head co-acting with a complementary notch in the hammer to provide self-centering action in the cocked position.
