A revolver of the swing-out cylinder type is provided with an improved ejector means the longitudinal travel or stroke of which is appreciably greater than that of conventional ejector means. The ejector means has a cartridge ejector portion for engaging the rims of cartridges contained in the chambers of the cylinder of the revolver and a generally tubular ejector guide portion slidably mounted on the rearward end of the cylinder and extending forwardly into the longitudinal center bore of the cylinder pivot shaft. The ejector spring that urges the ejector means to its normal forwardmost position has an outer ejector spring section disposed within the annular space between the tubular guide portion of the ejector means and the center bore of the cylinder pivot shaft and an inner ejector spring section of smaller diameter than the outer ejector spring section disposed on the rearward end of the ejector rod. An ejector spring connector means connects the forward end of the outer ejector spring section to the rearward end of the inner ejector spring section. The inner ejector spring section is disposed generally forwardly of the outer ejector spring section when the ejector means is at its forwardmost position and is disposed in telescopic fashion within the forward end of the outer ejector spring section when the ejector means is at its rearwardmost cartridge ejecting position.
In a revolver having a frame, a cylinder crane pivotally mounted on the frame, said cylinder crane having a rearwardly extending cylinder pivot shaft that is formed with a longitudinally extending center bore, a cylinder rotatably mounted on the cylinder pivot shaft of the cylinder crane, said cylinder being formed with a plurality of cartridge receiving chambers, ejector means mounted for longitudinal movement in the longitudinal center bore of the cylinder and cylinder pivot shaft, said ejector means having a cartridge ejector portion for engaging the rims of cartridges contained in the chambers of the cylinder and a generally tubular ejector guide portion slidably mounted on the rearward end of the cylinder and extending forwardly into the longitudinal center bore at the cylinder pivot shaft, said ejector means being movable longitudinally from its forwardmost cartridge receiving position to its rearwardmost cartridge ejection position, an ejector push rod connected to the forward end of the tubular guide portion of the ejector means, the ejector rod being slidably mounted for longitudinal movement on the cylinder crane, and a helically wound ejector spring disposed within the longitudinally extending annular space defined by the outer surface of the tubular guide portion of the ejector means and the inner surface of the longitudinal center bore of the cylinder pivot shaft, said ejector spring urging the ejector means and ejector rod to their forwardmost positions,
