A simplified revolver handgun comprises an interacting trigger and hammer mechanism which in their normal movements cause a transfer rod to move linearly inside the extractor assembly of the cylinder, the transfer rod having on its outside surface a network of grooves which mate with an inwardly directed protrusion in the bore of the extractor assembly, the network being a repeating series of cam action sections, each section including a location for firing when said hammer and a cartridge are aligned, and a location when the hammer rests in close proximity to the cylinder but between adjacent cartridges in a nonfiring position. Other optional features include (1) placing warnings of the dangers of a handgun on the outside of the cylinder and/or the handle; (2) providing a removable hammer nose to render the handgun safe when not in use; (3) a transparent inspection shield for viewing the bases of cartridges in the cylinder; (4) a means for moving the cylinder forward against the barrel to effect a gas seal during firing; (5) a means for using explosion gases to rotate the cylinder, cock the hammer, and eject spent shells from the cylinder; and (6) a revolver with a totally enclosed cylinder.
A revolver handgun having a revolving cylinder, a trigger and hammer mechanism that causes the cylinder to rotate when the hammer or trigger is moved, and an extractor assembly with a star shaped head, a central bore, and a shaft;
In a revolver handgun having a revolving cylinder aapted to contain a plurality of cartridges in an extractor assembly having a central bore and being keyed to the cylinder, a trigger mechanism and a hammer mechanism mechanically connected to said cylinder such that pulling of said trigger mechanism or cocking of said hammer mechanism causes said cylinder to rotate;
A revolver handgun having a barrel section and a handle section, said barrel section including a reciprocally movable trigger and a totally enclosed cylinder rotatable in a cylindrical recess in said barrel section, said barrel section and said handle section releasably lockable to each other and pivotably openable to make said cylinder slidably removable from said recess, said cylinder having on its outside surface a network of grooves to mate with a linearly reciprocable protrusion on said trigger whereby linear movement of said protrusion causes rotational movement of said cylinder, said network of grooves providing a pathway of repeating cam sections corresponding to the number of cartridge chambers in said cylinder, each cam section having a first location where said trigger is in its normal position of rest and a second location where said trigger is fully pulled to its firing position with a cartridge chamber of said cylinder aligned with the barrel;
