| 摘要 | A cartridge loading and extractor assembly includes an extractor segment carried on the rearward end of an extractor rod mounted for reciprocating movement relative to the cylinder. Rearward positioning of the assembly permits the successive placement of each cartridge partially into the respective chambers with the extractor segment engaging the extractor groove of each cartridge to retain them until forward movement of the assembly fully chambers the cartridges simultaneously. | ||||||
| 权利要求 | 1. A cartridge loading and extractor assembly for use in a revolver having an annular array or cylindrical chambers accommodated in a cylinder, said assembly comprising, in combination: A. a rod mounted concentrically with the cylinder for reciprocating movement relative thereto; B. a disc mounted on an end of said rod for movement between a forward position adjacent the rear face of the cylinder and a rearward position spaced from the rear cylinder face; and C. means forming an annular array of curved notches in the periphery of said disc, each in axial alignment with a different one of the chambers, each of said notches having a radius of curvature less than the radius of curvature of its corresponding cylindrical chamber, said notches being arranged to engage extractor grooves formed in cartridge cases such as to concurrently fully insert the cartridgEs in the chambers when said disc is moved from said rearward position to said forward position and to concurrently extract spent cartridges from the chambers when said disc is moved from said forward position to said rearward position. 2. The assembly defined in claim 1, which further includes a spring acting on said rod to bias said disc into said forward position. 2. said disc operating to concurrently extract spent cartridges from the chambers incident to movement from said forward position to said rearward position, the spent cartridges readily falling to the ground. 3. The assembly defined in claim 1, wherein the cartridges are of the rimless type having a case tapered in the direction of its open end and the chambers have an entrance bore opening into the rear face of the cylinder tapered in conformity with the cartridge case, whereby initial clearance is provided between the cartridge and the bore to accommodate partial insertion therein of the cartridges pursuant to engaging said notches in the extractor grooves while said disc is in said rearward position. 4. In combination with a revolver having a cylinder provided with cylindrical chambers with tapered entry bores for accommodating a rimless cartridge having a case tapered in the direction of its open end, a cartridge loading and extractor assembly comprising, in combination: A. a rod mounted concentrically with the cylinder for reciprocating movement relative thereto; B. a disc mounted on an end of said rod for movement between a forward position adjacent the rear face of the cylinder and a rearward position spaced from the rear cylinder face; and C. means forming a semi-circular notch in the periphery of said disc in axial alignment with each chamber, each of said notches having a radius of curvature less than the radius of curvature of its corresponding cylindrical chamber, 5. The assembly defined in claim 4, which further includes a spring acting on said rod to bias said disc into said forward position. |
