摘要： 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).
