    摘要： A single trigger sequential firing mechanism for a double barrel firearm fires the two barrels or chambers successively upon successive trigger actuation, without need for a separate selector switch. The firing pins are driven by linear motion of corresponding pistons or plungers, rather than by arcuate motion of pivoting hammers. The present invention is adaptable to various double barrel gun configurations, but is particularly adaptable for use with over and under double barrel shotguns. Three different embodiments are disclosed, with each having identical parts and components with the exception of the upper portion of the trigger body. The first embodiment fires the two barrels successively upon successive pulls of the trigger. The second embodiment fires the two barrels after a first trigger pull and a subsequent release of the trigger. Finally, a third embodiment fires the two barrels upon successive trigger releases, after the trigger has been pulled.

    摘要翻译： 用于双筒火器的单个触发器顺序击发机构在连续的触发器致动时依次触发两个桶或室，而不需要单独的选择器开关。 点火销由对应的活塞或柱塞的线性运动驱动，而不是通过枢转锤的弓形运动。 本发明适用于各种双枪枪配置，但是特别适用于双枪炮和双炮枪枪。 公开了三个不同的实施例，每个具有相同的部件和部件，除了触发器主体的上部。 第一实施例在触发器的连续拉动时连续地触发两个筒。 第二实施例在触发器的第一触发器拉动和随后的释放之后触发两个桶。 最后，第三实施例在触发器被拉动之后在连续的触发释放时触发两个桶。
