    • A multiple positionable selector arrangement for a bolt action firearm positioned adjacent the bolt handle (14) which selector (26) carries a cam (46) and a selector handle. Associated with the selector (26) are trigger restraining means and a bolt handle blocking plunger means (15). The selector arrangement (26) is movable to a first active position to cause the trigger restraining means (15) to restrain the trigger (22) and sear (32) so the firearm cannot be discharged and the selector arrangement (26) is movable to a second active position to cause the plunger (52) means to restrain the bolt handie (14). In the second position, the selector handle (26) also serves to prevent substantial forward movement of the cocking piece (17).
    • 一种用于与所述螺栓手柄(14)相邻定位的螺栓动作火器的多重定位选择器装置,所述选择器(26)承载凸轮(46)和选择器手柄。 与选择器(26)相关联的是触发抑制装置和螺栓手柄阻塞柱塞装置(15)。 选择器装置(26)可移动到第一有效位置以使触发器限制装置(15)限制触发器(22)和烙铁头(32),使得枪支不能被排出,并且选择器装置(26)可移动到 第二活动位置,以使柱塞(52)装置限制螺栓手柄(14)。 在第二位置,选择器手柄(26)还用于防止起动片(17)的大量向前运动。

    • A revolver having essentially conventional cylinder (12), trigger (14), and cylinder pawl (26) is provided with a novel and positive acting cylinder latch arrangement (23, 24, 35, 36, 42) wherein the trigger (14) has a trigger pivot portion (44) formed with a transverse pivot hole (54) and with a longitudinally extending actuator receiving slot (51) through which the trigger pivot pin (22) extends, a cylinder latch actuator (42) is slidably mounted within said actuator receiving slot (51) and on said trigger pivot pin (22) for limited longitudinal and rotational movement on said pin (22) within said slot (51), and a cylinder latch (23) is pivotably mounted for rotation of the nose portion (35) thereof into and out of engagement with the cylinder latch notches (18) formed in the outer surface of the cylinder (12). Rotation of the trigger (14) from its at-rest position to its ready-to-fire position causes the cylinder latch actuator (42) to contact and depress and then to release the cylinder latch (23) thereby causing the nose portion (35) of the cylinder latch (23) to rotate out of engagement with one of the cylinder notches (18) and then to rotate into engagement with the next cylinder latch notch (18) of the cylinder (12). Rotation of the trigger (14) in the opposite direction causes the cylinder latch actuator (42) to press against the cylinder latch (23) and thereby to move the cylinder latch actuator (42) longitudinally rearwardly a sufficient distance to allow the forward end of said cylinder latch actuator (42) to clear the rearward end of said cylinder latch (23).
