Abstract:
A 0.22 caliber long rifle removable conversion system kit for open top frame, black powder, ball and cap reproduction and replica revolverâ€”recreation and gallery shooting, comprising;two barrel tubular sleeves of different length, the shorter barrel tubular sleeve and a longer barrel sleeve, the short sleeve having an inlet, outlet, inside diameter, outside diameter and a central aperture, the outside diameter of the outlet is threaded and sized to fit loosely within the barrel of a black powder pistol, the inlet being configured in a flange-like shape having a smaller and larger component, the smaller component having a round cylinder like shape with a plurality of raised dimple to fit tightly into the inlet of the barrel rifling of the pistol, the large portion of the inlet being disc shaped, the long barrel sleeve is made of a tube having at one end a thread and the other end the lip and the raised dimple; a long barrel nut comprising a round cylindrically shaped tube having an outside tapered threaded end with four letting slits having at the end four letting apertures, the tube also having an internal thread at the same end; the long barrel nut is locked with the locking nut; a short barrel sleeve nut comprising an inlet and an outlet and a portion therein between each having an inside and outside diameter and a central aperture, the outside inlet diameter being round and sized to fit snugly within the inside diameter of a pistol barrel with an inside diameter of the nut inlet being threaded and sized to mate with the threaded portion of the threaded barrel tubular sleeve outlet, and the outlet portion of the nut being larger, approximating the outside diameter of the pistol barrel; a firing pin ring assembly comprised of a loading gate subassembly and a firing pin subassembly and a firing pin ring, the firing pin subassembly having inboard and outboard components, the inboard component comprising a solid cylinder having a flat striking end and an outboard component of the firing pin subassembly being a solid cylinder with a threaded aperture, the firing pin ring having an inboard and outboard face and a generally cylindrical configuration with a central aperture through the ring, a recess surrounding the central aperture, and firing pin subassembly aperture comprising a spring nest aperture, a subassembly locking screw aperture for a locking screw below and tangent to the firing pin subassembly aperture, above the firing pin subassembly aperture at the upward most edge of the cylinder is a stepped groove perpendicular to the outboard face, with the lower quadrant surface, encompassing between about 75 and 100 degrees of circumference a flattened surface to receive the frame of the pistol with the flattened area creating two retention points, a loading gate locking pin nest aperture in the ring above and parallel with the flattened surface of the lower quadrant of the firing pin ring, a loading gate pivot aperture inboard from the outboard surface of the firing ring above the locking pin nest and running perpendicular to the outboard surface, the firing pin ring being interrupted and opened by a wedge-shaped cut with an inner radius cut, a congruously-shaped loading gate subassembly comprising a loading gate with an attachment tab and a loading gate pivot pin and a gate locking pin which is mated to the opening, being rotatable about 90 degrees around the pivot pin, with the locking pin capable of retaining the gate in an open and closed position; a cartridge cylinder with a central aperture and with locking lug depressions on the outside surface and full length cartridge apertures in a circular equally spaced circumferential orientation around a central shaft aperture with a rotation ratchet to mate with and engage the existing pistol frame; and a barrel wedge assembly comprising a wedge subassembly and an unloading rod assembly, the barrel wedge subassembly comprising an expanding wedge portion and an extraction portion, the unloading rod assembly, comprising an unloading rod and an unloading rod housing, the unloading rod being shaped in a U and a circumferential groove around the outside diameter of the rod, the housing being L shaped and having an aperture through the length of the short leg of the L allowing the rod to be housed within the aperture, the housing also having a through aperture to house a spring and a pin and a screw, the pin intersecting the aperture of the housing perpendicular to the path of the rod.
