Abstract
A revolver has a detent mechanism providing positive mechanical engagement between the cylinder yoke and the frame. A housing mounted on the frame has a spring biased plunger that transversely engages a pin. The pin projects from the housing and engages a recess on the yoke when the revolver cylinder is closed. The pin is biased into engagement with the recess by the plunger to maintain the revolver closed and the chambers of the cylinder in precise alignment with the barrel during firing. Manual force applied to the cylinder can overcome the biasing force and permit the revolver to be opened and closed.

A revolver, comprising:
- a frame;
- a yoke mounted on said frame and movable about a pivot axis between an open and a closed position, a recess being positioned within said yoke;
- a cylinder mounted on said yoke;
- a detent mechanism, comprising:
- a housing mounted on said frame adjacent to said yoke;
- a pin bore positioned within said housing, said pin bore extending longitudinally along a pin bore axis;
- a plunger cavity positioned within said housing and intersecting said pin bore, said plunger cavity extending longitudinally along a plunger cavity axis, said plunger cavity axis being oriented transversely to said pin bore axis;
- a pin having a tip, said pin being positioned within said pin bore and movable along said pin bore axis between a first position, wherein said tip projects from said housing and engages said recess when said yoke is in said closed position, and a second position, wherein said tip is within said housing;
- an action surface positioned on said pin, said action surface being oriented transversely to said pin bore axis;
- a plunger having an end, said plunger being positioned within said plunger cavity and movable along said plunger cavity axis;
