| Disclosed is an ammunition cartridge case that includes a sleeve, a base fixedly attached to the sleeve and a fiber reinforced polymer composite annulus that is at least partially within the base. In certain embodiments, the sleeve and the base are formed partly or entirely from a metal, for example steel or stainless steel. The base has a central aperture that affords for the annulus ring to fit within. The annulus is dimensioned such that it fits securely within the central aperture of the base and has a center aperture wherein a primer can be located. The annulus ring contains a volume of composite fibers ranging from 10 to 90 volume percent. The annulus isolates the primer from the cartridge case and thereby prevents galvanic corrosion between the primer and case. In addition, a metallic foil can be present between the annulus and the cartridge case in order to assure proper securement of the annulus therewithin. | ||||||

| A device for loading a primer from a priming station into a primer socket of an ammunition cartridge case, includes an elongated track for longitudinally guiding a rectilinear primer strip through the priming station. The primer strip includes a series of longitudinally aligned receptacles, each of which holds a primer in an interference fit that prevents dislodgement of the primer from the strip. Each primer strip also has a plurality of laterally extending castellations or teeth that slide on a ledge over the track, and a reciprocating advancing member on the track has arms that interdigitate with the teeth to move the primer strip forward through the priming station as the advancing member moves in an advancing direction. A detent interdigitates with the teeth to hold the primer strip with a target receptacle in a target position adjacent the primer socket of the cartridge case, while a reciprocating punch pin transfers the primer from the target receptacle to the primer socket. The primer strips provide a compact storage member that safely and conveniently allows primers to be loaded into spent ammunition cartridges. | ||||||
| 55 | Tolerance compensating assembly/positioning system and method of use | US56864 | 1993-05-05 | US5341717A | 1994-08-30 | Richard L. Feldman |
| The present invention is an assembly/positioning system and method of use for application in the insertion or placement of tolerance dimensioned first process elements in tolerance dimensioned holes in or with respect to surfaces of second process elements. The system safely, precisely, repeatably and consistently compensates for tolerances in dimensions of process elements assembled therein, and for internal assembly/positioning system element tolerances which result from system stresses or temperature effects etc. during use. The assembly/positioning system also allows positioning process elements for processing and can include process element processing means internally. The assembly/positioning system utilizes mechanical or hydraulic toggle, insertion and tolerance compensation means in conjunction with mechanical transfer means to allow use with any combination of relatively large toleranced process elements. The assembly/positioning system provides a user simultaneous and totally independent control of both insertional and gauging forces. Multiple transfer, toggle, insertion and tolerance compensating means can be simultaneously but independently operated from a single control system. The method of use does not require a shut height depth set-up or require a practitioner to develop a "feel", read or set dials or repeatedly handle toleranced dimension process elements assembled within the system, or to have any ability beyond that which allows following a set procedure. | ||||||

| 58 | Cartridge primer feeder | US622966 | 1984-06-21 | US4542677A | 1985-09-24 | Richard J. Lee |
| A body having an axial bore is fixed in an ammunition cartridge reloading press which has an actuated ram. The bore contains a punch that is retracted by a spring away from a cartridge that is mounted in a holder and is to have a primer inserted. An open trough conducts primers in a row from a storage tray to a chamber at the upper end of the punch. A pin on the ram of the press drives the punch for it to press a primer into the cartridge in opposition to the spring. The terminal end of the trough is cylindrical and fits into the body's axial bore to allow the trough to pivot and advance primers by vibration. The terminal end has a hexagon bore to provide clearance for the round punch that passes through it so stray propellant dust can sift away safely. In one embodiment a rod extends laterally from the trough and rubs on the press frame during a ram stroke to thereby flex and vibrate the trough and tray to induce advancement of the primers. | ||||||

| 60 | Reloading apparatus having improved primer mechanism | US150802 | 1980-05-19 | US4329906A | 1982-05-18 | Edward A. Heers |
| A reloading apparatus removes used primer caps and inserts new primer caps into the base of casings substantially automatically. The apparatus includes a ram for holding a casing and for moving the casing relative to a reconditioning means for reconfiguring the casing to a desired, predetermined configuration. The ram carries a primer arm movable automatically between a first, non-priming position during the time the casing is being deprimed and a second, priming position after the casing has been deprimed. The ram is provided with a longitudinally extending slot having a pivot pin. The primer arm includes a first member disposed within the slot and releasably connected to the pivot pin. The primer arm includes a second member extending outwardly of the slot and engageable with a stationary portion of the reloader. A primer cap holder is located at the intersection of the first and second members. Upon movement of the ram toward the priming position, the second member engages the stationary portion and causes the primer cap holder to be pivoted into the ram slot. Further movement of the ram toward the priming position causes the primer arm to move relative to the ram and the casing and a primer cap eventually is pressed into the base of the casing. Upon movement of the ram to the non-priming position, the weight of the primer arm causes the primer arm to pivot about the pivot pin and move out of the slot. A new primer cap then can be inserted into the primer cap holder for use in a subsequent priming operation. | ||||||
