UNITED STATES PATENT APPLICATION OF ROGER J. CURRAN FOR EXTRACTOR ASSEMBLY FOR RIMLESS CARTRIDGES ABSTRACT OF THE DISCLOSURE Disclosed is an extractor assembly including an extrac- tor rod splined within a revolver cylinder and carrying spring leaf extractor segments in elongated grooves about its outer sur- face. The segments are prebent and biased in the assembly to displace extractor tips carried thereby radially outwardly. When the extractor assembly is fully seated within the revolver cylin- der, cam surfaces on the cylinder maintain the extractor tips spaced radially inwardly of the cylinder chambers. Upon axial displacement of the extractor assembly, the extractor tips, under the natural bias of the segments move radially outwardly into the grooves of the cartridge casings whereby the tips displace the casings rearwardly from the cylinder chambers. Upon spring return of the extractor assembly into the cylinder, the extractor tips are cammed radially inwardly and out of the chambers enabling the cylinder to be loaded.
