Abstract A revolver is constructed in two interlocking subassemblies, thereby avoiding the traditional side plate assembly techniques conventional in revolver construction. A cylinder is mounted on the first, or frame, subassembly and is provided with a series of indexing grooves spaced in conventional fashion. The indexing grooves include an entry channel with a ramped bottom sloping to an indexing well. The indexing well is configurated with a check surface opposite the entry channel and substantially normal the outer surface of the cylinder. The second, or trigger guard, subassembly carries the entire firing and indexing mechanisms of the revolver including a cylinder stop member. The engaging end of the stop member has a sloped or ramp end, and is configurated in substantial conformance with the indexing well. With the two subassemblies joined, the stop member is positioned to register with the grooves in turn as the cylinder is rotated, thereby to precisely register the chambers of the cylinder with the barrel of the revolver.

Claim 1
Independent Claim
215 words
In a revolver including means for spinning a cylinder mounted within a frame in response to pulling a trigger to bring individual chambers of the cylinder sequentially into registration with a bore of a barrel attached to said frame, the improvement which comprises: a series of indexing grooves arranged in a ring around the outer surface of the cylinder, one such groove corresponding to each chamber of the cylinder and each of said grooves comprising a shallow ramp portion at the leading end of the groove and a well portion at the trailing end of the groove terminating in a check surface; stop means normally biased to register with the well portion of the groove corresponding with a chamber in registration with the bore of the barrel including a projection with a ramped distal surface to permit partial entry of said projection into said well as the cylinder is advanced towards its registered position; and linkage means cooPerative with said stop means and said trigger to retract said stop means from said well portion in response to pulling of said trigger to permit said cylinder to rotate and thereafter to release said stop means to engage the ramp portion of the next succeeding groove before the corresponding chamber is urged into registration with said bore.

In a revolver including means for spinning a cylinder mounted within a frame in response to pulling a trigger to bring individual chambers of the cylinder sequentially into registration with a bore of a barrel attached to said frame, the improvement which comprises: a series of indexing grooves arranged in a ring around the outer surface of the cylinder, one such groove corresponding to each chamber of the cylinder and each of said grooves comprising a shallow ramp portion at the leading end of the groove and a well portion at the trailing end of the groove terminating in a check surface; stop means normally biased to register with the well portion of the groove corresponding with a chamber in registration with the bore of the barrel including a projection with a ramped distal surface to permit partial entry of said projection into said well as the cylinder is advanced towards its registered position; and linkage means cooPerative with said stop means and said trigger to retract said stop means from said well portion in response to pulling of said trigger to permit said cylinder to rotate and thereafter to release said stop means to engage the ramp portion of the next succeeding groove before the corresponding chamber is urged into registration with said bore.
Claim 3
Dependent Claim
24 words
The improvement of claim 1 wherein the registering portion of said projection is configurated to conform substantially with the well portion of said grooves.
Claim 4
Dependent Claim
59 words
The improvement of claim 1 wherein said stop means is mounted to the frame of said revolver by means which permit engagement by said trigger to pull said stop means from engagement with a said groove and release by said trigger while said trigger is still pulled to permit engagement by said stop means of said next succeeding groove.
