Abstract
A semi-automatic double action revolver having an axially slidable and rotatable barrel aligned with a lower chamber of a top pivotal swing-out cylinder. The trigger mechanism includes a safety rod to prevent the opening of the cylinder while the hammer is cocked, or not in the rest position, and a transfer bar is provided between the hammer and the firing pin so that the firing pin can only be actuated when the trigger has been pulled all the way back, beyond the double action and single action hammer cock position.

In a semi-automatic, double action revolver having a frame, a rotatable cylinder including a plurality of circumferentially disposed, axially extending chambers containing bullets, a trigger mechanism including a trigger and a hammer mechanism including a hammer and a firing pin, a cylinder latch including a latch pin, the improvement comprising, a barrel aligned with the lowermost chamber of the cylinder, said barrel having a rifled bore adapted to be engaged by a bullet when travelling therethrough, said barrel being slidably and rotatably mounted in said frame, spring means mounted between said frame and said barrel for biasing said barrel in a direction toward said cylinder, whereby upon firing the revolver the thrust of the bullet engaging the rifled bore causes the barrel to rotate and slide forwardly compressing the spring to thereby absorb the initial shock and thrust imparted to the barrel.
In a semi-automatic double action revolver having a frame, a rotatable cylinder, a cylinder latch, the improvement comprising, providing the cylinder with a top pivotal crane assembly comprising, a shaft having one end secured to the cylinder, the opposite end of said shaft being rotatably mounted in said frame, a torsion spring mounted in said frame, one end of said torsion spring being connected to said opposite end of said shaft, the opposite end of said torsion spring being connected to the frame, whereby upon release of the cylinder latch the torsion spring urges the cylinder to the open position.
