Abstract
An improved break-top handgun of the revolver type is disclosed which incorporates an improved latching mechanism for securely linking the barrel section and frame together and which compensates for any wear occurring on the engaged surfaces. Also disclosed is an improved linkage connected to the trigger for freeing the ammunition-holding cylinder for rotation and means for retaining the cylinder in engagement with the barrel when the barrel section is separated from the frame for cleaning, loading and/or unloading ammunition.
Claims10
A latch mechanism for a break-top handgun of the revolver type, comprising:
- a frame including an integral handle, hammer, firing pin, and trigger operatively attached to the hammer;
- a barrel section including a rotatable ammunitionholding cylinder pivotally attached to the frame for movement between a first position for firing of the gun and a second position exposing the rear end of the cylinder for loading ammunition, unloading ammunition and cleaning of the cylinder or gun barrel;
- an upwardly inclined planar surface extending rearwardly from the entrance end of the barrel section;
- a latch assembly pivotally mounted to the frame for movement between a first position holding the frame and barrel section in fixed position relative to one another when the gun is to be fired and a second position where the barrel is broken away from the frame, the latch assembly including a pivotable latch member having a separately rotatable planar surface positioned for engaging the upwardly inclined planar surface on the barrel section when in the first position to prevent separation of the barrel section from the frame during firing and to compensate for wear of the upwardly inclined planar surface or the latch assembly caused by repeated opening and closing of the barrel section relative to the frame of the gun;
- and
- means biasing the latch member forwardly to engage the separately rotatable planar surface against the upwardly inclined planar surface.

- a latch assembly pivotally mounted to the frame for movement between a first position holding the frame and barrel section in fixed position relative to one another when the gun is to be fired and a second position where the barrel is broken away from the frame, the latch assembly including an upside-down U-shaped latch member whose respective legs are pivotably attached to each side of the frame, the base of the "U" of the latch member having a rotatable planar surface for engaging the upwardly inclined planar surface on the barrel section in the first position to prevent separation of the barrel section from the frame during firing and to compensate for wear of the latch assembly caused by repeated opening and closing of the barrel section relative to the frame of the gun, the rotatable planar surface including a rotatable pin having a planar surface adapted to engage the inclined planar surface on the barrel section;
- and
- means biasing the latch member forwardly against the upwardly inclined planar surface engaged by the latch member.

- and
- means biasing the latch assembly forwardly to engage the engagement member planar surface against the upwardly inclined planar surface.
