Abstract
Abstract A universal cartridge holder for supporting cartridge cases having a rim disposed at one extremity thereof and comprising a base element that is adapted to be received by the upper slotted extremity of the ram of a cartridge reloading press. About the base element may be positioned a housing having a cam surface formed therein, which cam surface may react against cam surfaces defined on a plurality of cartridge retaining segments that are disposed within the housing and are supported by the base element. The segments may be continuously urged to a position releasing engagement thereof with the rim of the cartridge and may be moved, by cooperative relationship between the internal cam surface of the housing and the cam surfaces of the segments, into a gripping or holding relationship with the rim of the cartridge. The housing may carry a second oppositely directed cam element cooperating with biased detent means carried by the base element to develop a resultant force that urges the housing in a direction tending to cause the cooperating cam surfaces to move the segments to the gripping position thereof.
