| 161 | MULTI-COMPONENT BULLET WITH CORE RETENTION FEATURE AND METHOD OF MANUFACTURING THE BULLET | US14589359 | 2015-01-05 | US20150338198A1 | 2015-11-26 | Thomas J. Burczynski; Jason Imhoff |
| A three component bullet with an improved core retention feature and a method of manufacturing the bullet includes a cylindrical jacket having an open end and a closed end containing a malleable metal core which is forced into a forming die having a bottleneck shaped interior, wherein the outside diameter of the open-ended forward portion of the jacket is smaller than the outside diameter of its closed rearward portion. The open end of the pre-form may be dropped through or forced through a malleable non-rigid locking band. A relatively tight-fitting punch enters the open end of the pre-form, to radially swell the core and subsequently portions of the jacket fore and aft of the non-rigid locking band, thereby securing the non-rigid locking band in place. An inwardly-extending annular band of jacket material embeds itself into the core material to lock the core inside the jacket. | ||||||

| A non-discarding sabot projectile consists of a projectile core; a lower core casing for insertion into a bore of a muzzleloader firearm; and an upper core cap fastly engaged with the lower core casing. Such an engagement between the upper core cap and the lower core casing defines a jacket so that, upon assembly of the lower core casing and upper core cap, the projectile core is encapsulated within the jacket. | ||||||

The substantially cylindrical insert includes a top surface opposite a bottom surface and a substantially cylindrical coupling element that extends from the bottom surface, a primer recess in the top surface that extends toward the bottom surface, a primer flash hole positioned in the primer recess to extend through the bottom surface, and a flange that extends circumferentially about an outer edge of the top surface. The substantially cylindrical polymeric middle body includes a substantially cylindrical polymeric bullet-end and a substantially cylindrical polymeric coupling end connected by a powder chamber, wherein the substantially cylindrical polymeric coupling end extends over the substantially cylindrical coupling element and covers a circumferential surface of the primer flash hole. | ||||||
| 164 | Shotgun Shell Tracer and Tracer Manufacturing Device | US14199122 | 2014-03-06 | US20140261043A1 | 2014-09-18 | Wendell Diller |
| A shotgun shell tracer includes a base wall, an obturator, and an edge wall extending from the base wall opposite to the obturator. A chamber support may be engaged to the base wall extending from the base wall within the internal space of the tracer. The shotgun shell tracer may additionally include a tracer insert which may encircle the chamber support. Discharge of a shotgun shell in some embodiments will exert pressure on projectiles which fuse the tracer insert to the base wall and the chamber support, and embed the projectiles into the tracer insert, establishing ballast for the shotgun shell tracer. The chamber support in one embodiment may be a modified spike. The ballast in one embodiment may be a washer replacing embedded projectiles. A conveyor may be used to transport tracer carriers during manufacture of a tracer. | ||||||

| A method and apparatus for filling a shell body with sub-projectiles in a predefined geometric arrangement and in a very short time without creating shifting errors is provided. Prior to filling the shell body, the sub-projectiles may be combined into layers which are as thick as the length of the sub-projectiles and which extend in planes transverse to a longitudinal axis of the shell body. The sub-projectiles take up a position in the layer which corresponds to their geometric arrangement in a hollow chamber of the shell body. During the combination, the outer periphery of the layers may be shaped so that, following insertion of the layer into the hollow chamber, the sub-projectiles may be held there and fixed against relative rotation while maintaining the previously formed geometric arrangement. In accordance with a preferred embodiment, the outer periphery of the layers may assume a hexagonal shape where the axes of the cylindrical sub-projectiles are aligned with the longitudinal axis of the shell body. | ||||||
| 177 | Machine base for supporting loading press | US232489 | 1994-04-25 | US5713626A | 1998-02-03 | Gerald L. Tokarski |
| A base for locking and supporting a cartridge loading press and an operator, which can be easily and quickly reconfigured from a storage configuration to a working configuration, and vice versa. The base includes a frame, an operator support seat secured to the frame, a loading press supporting platform secured to the frame at a location vertically higher than the seat, a ring secured to the frame below the supporting platform, and a detachable cross member. In the storage configuration, the detachable cross member is detached from the frame and the effective frame width is reduced to seven inches, which permits the base to be stored under a bed. In the working configuration, the detachable cross member is attached to the frame and the effective frame width is increased to stabilize the base and permit the weight of the press, base, and operator to be more efficiently distributed across the floor. In either configuration the operating lever of the press can be locked to the base through the ring by a long shackle lock. | ||||||
| 178 | Propellant grains and process for the production thereof | US515386 | 1995-08-15 | US5619073A | 1997-04-08 | B. Kelley Posey; David M. Hurley; R. David Seybert; M. Russel Phinney |
| A batch process produces unitary grains of propellant material. A constituent mixture of the material is prepared by mixing constituents while heating to at least a predetermined pouring temperature within a permissible temperature range. The constituent mixture is poured into a mold, while vibrating it to avoid voids or interfaces within the material, to cast a block of propellant. The cast block is cured for a predetermined period resulting in a cured, cast block of semirigid yet plasticly deformable material. A hydraulic press with a ram carrying a tubular cutting die is positioned, as by transferring the mold without its bottom to the press bed, for permitting grains to be cut by movement of the press ram by forcing the cutting die into the cast block to cut from the block a grain of the propellant material, then extracting the grain for further use. The cutting cycle is repeated until the cast block has yielded a satisfactory number of grains. Preferably, inert dowel plugs are inserted into each cut cavity after the grain is extracted to maintain dimensional stability of the block for successive cutting cycles. A propellant grain produced by such process is of unexpectedly high quality. | ||||||
| 179 | Method and a device for filling a space in an ammunition unit with explosive | US529458 | 1990-05-29 | US5062343A | 1991-11-05 | Per Sjoberg |
| The present invention comprises a method and apparatus for filling a space in at least one ammunition unit with a ready-mixed explosive containing a substance which imparts high viscosity to the explosive. The method comprises supplying the explosive into a flexible container with a single opening therein, positioning the flexible container into a second container adapted to withstand high internal pressure, applying a high pressure into the second container thereby exposing the flexible container to the high pressure, and pressing out the explosive from the flexible container through the opening in the flexible containers into the space in the ammunition unit upon application of the high pressure whereby filling the space with the explosive. | ||||||
