Ratchetless gun

Image Number 7 for United States Patent #4581835.

A novel indexing system for revolvers is disclosed in which a trigger-actuated finger grabs one of a plurality of circumferentially-spaced notches on the rim of the chambered cylinder and rotates the cylinder through the required arc, as the trigger is being pulled, to advance the next chamber to its proper firing position.The finger is part of a modular unit which fits into a complementary recess of the revolver's frame and takes the place of the standard "hand-and-ratchet" combination for rotating the cylinder. The module forms part of the recoil face and includes a stop for precisely registering the rotated chamber with the revolver's barrel just prior to firing.
