This invention relates to an improved lock for revolver cylinders of the type that releasably locks the latter against rotation by passing a rod from the barrel into one of its chambers, such improvement being characterized by a loose-fitting lock rod of a length greater than that of the cylinder but shorter than the combined lengths of the latter and the barrel, a friction-held keeper for insertion into the barrel ahead of the lock rod for the purpose of keeping it in place, and an extractor capable of being connected to the keeper upon insertion into the barrel for purposes of retrieving it preparatory to removing the lock rod. The extractor includes as a part thereof a normally recessed indicator attached to the front end of a probe which projects out the rear end and through an axial opening in the keeper to where it engages the front end of the lock rod so as to extend the indicator and thus provide the user with visual confirmation that the lock rod is fully seated in the cylinder.

For use with a revolver of the type having a barrel, a multi-chambered cylinder mounted for rotation within an opening in a frame mounting the barrel and a trigger mechanism operative upon actuation to bring the cylinder chambers into axial alignment one at a time with the barrel bore, a cylinder lock assembly for preventing rotation of the cylinder which comprises: a lock rod sized to loosely fit inside the barrel bore and being of a length less than the combined lengths of said barrel and the chamber aligned therewith but greater than the length of said chamber alone; a keeper in the form of a frictionally-held plug insertable into the barrel bore and effective when so positioned to hold the lock rod therein, said keeper having a rear end proximate the lock rod, a front end carrying a first connecting means engageable by a tool for extracting same, and an axial opening extending between the ends thereof; and an extractor having a rear end sized for insertion into the barrel bore and a front end, second connecting means carried by said rear end releasably connectable to said first connecting means on the front end of the keeper for placing the latter in the barrel bore and retrieving same therefrom, said extractor also having an axial opening therethrough and a pin mounted within said opening for reciprocal movement relative thereto between an extended and a retracted position, said pin having a front end and a rear end and an overall length greater than the combined lengths of the keeper and extractor when connected together, said pin in retracted position with the extractor and keeper thus interconnected extending all the way through the latter and beyond the rear end thereof into position for engagement with the near end of the lock rod when the remote end thereof is seated against the portion of the frame behind the cylinder after having passed through said aligned chamber thereof, and the front end of said pin in extended position brought about by deeper insertion of said interconnected extractor and keeper into the barrel bore with said pin contacting the lock rod providing an observer with a visual indication that said rod is thus seated.
