Shell Patents (Class 86/46)
  • Patent number: 8783509
    Abstract: A method, device and system for metering powder material from a powder material source by a metering device connected to the source. The device is charged from the source with a batch of powder material in a charging configuration. The batch is discharged from the device in a discharging configuration. The source is connected with a metering piston space in the charging configuration via a first channel of a fixed metering channel hub. The volume of the space is controlled between a metering piston and a hub peripheral surface by controlling the piston position in the space, to charge the volume with material by gravity. The metering space is turned around the hub, to the charging configuration. The volume filled with material is enclosed until reaching the discharging configuration. The metering piston space is connected with a discharge opening via a second channel of the hub for discharging the material.

  • Patent number: 6769344
    Abstract: An arrangement for retrieving large-caliber ammunition from an ammunition magazine and transferring these to a loading and ramming position, in which the respective ammunition unit is located directly behind and coaxially aligned with a barrel of a large-caliber weapon mounted in such a way that it can pivot around a horizontal axis to assume different elevation positions. The transferring arrangement comprises a swing arm pivotably mounted around the horizontal axis between a retrieving position and a delivery position for each ammunition unit, and an ammunition pickup unit which is mounted on the swing arm in such a way that it can pivot. The ammunition pickup unit is arranged to assume a first angular position relative to the swing arm when this assumes its retrieving position, and to assume a second angular position relative to the swing arm when this assumes its delivery position.

  • Patent number: 6516697
    Abstract: An improved spent shell carriage container, storage and dispensing hopper system provides two structures which can be added to a standard sized bucket, one structure through direct mounting and the other through drop insertion, to produce a spent shell carriage container and dispensing hopper. The direct mounting structure is simply a latch to hold a lower portion of the drop in structure in the closed position. The drop in structure includes a first member which can be shaped to gather support from the inside of the bucket to provide an angled approach to a second member acting as a door. The second member is sized as a partial cup to prevent, limit and stabilize the spent shells appearing and passing through the opening so that a hand sized accumulation will be available for quick manual engagement and loading on the reloading equipment.

  • Patent number: 5335578
    Abstract: The present invention provides a retrofitting shell feeding attachment for shotgun shell reloading machines. The invention includes a declined tray held by a forked tray support, a funnel tube member leading from a discharge port located in the tray, and a feed tube leading from the funnel tube member and into a plunger block device. The plunger block device uses a linkage mechanism joined to a shell sliding member to automatically translate the vertical reciprocating motion of a plate member on the machine into sequential horizontal motions for sliding the shells discharging from the feed tube into proper loading position underneath the plate member.

  • Patent number: 5313869
    Abstract: A shell plate for being indexed in angular steps is on a carrier which is, in turn, mounted to the upper end of the reloader ram. Indexer rod engageable elements such as cylindrical equiangularly spaced apart pins project downwardly from the bottom of the shell plate. An indexer rod is carried in the shell plate carrier. When the ram is driven to nearly its lowermost position, the manual operating lever is near the end of its swing at which time it abuts the indexer rod for the latter to engage one of the pins to rotate the shell plate. The indexer rod is retracted and reset by having it slide down a guide track from the uppermost position of the ram and the guide track is angulated in part to be engaged by the rod and retracted. The reloader is distinguished by indexing the shell plate only when the ram is within a few millimeters of its lowermost limit.

  • Patent number: 4766798
    Abstract: To permit automatic ejection of shells in a progressive shell loader, a cam is mounted near the turret holding the shells. As the carriage is raised and lowered, two pawls and an index wheel turn it so that the shells advance toward a final station. Immediately prior to the final station, the cam engages a spring-biased lever to cause it to eject the reloaded shell. The pawls engage camming surfaces formed on the bottom of a single-piece index wheel to turn it.

  • Patent number: 4736667
    Abstract: A speed-loading device comprising a container having an interior chamber and a discharge opening leading from the chamber to the exterior of the container. The container has a storage section in the chamber for storing cartridges in side-by-side relationship and an orienting section in the chamber between the opening and the storage section. The container can be oriented so that the cartridges in the chamber can fall by gravity from the storage section through the orienting section and out through the discharge opening. A removable blocking member blocks the flow of cartridges out through the discharge opening. The orienting section rotates the cartridges as they fall through the orienting section toward the discharge opening so that the cartridges fall end first through the discharge opening.

  • Patent number: 4718319
    Abstract: The casings are guided through a supply duct to a sorting roller which possesses an arresting duct with a pin extending axially and, in the same cross-sectional plane, a transit duct. Those casings which arrive with the casing base directed upwardly penetrate into the arresting duct, with the case base resting on the free end of the pin. On subsequent rotation of the sorting roller through 180.degree., the casing falls into the outlet duct with base directed downwardly. Casings, which arrive with base pointing downwardly, run up against the pin and rest on the periphery of the roller until, after 180.degree. rotation of the transit duct, they align with the supply duct and can fall unhindered into the outlet duct. All casings fall into the outlet duct with their base directed downwardly.

  • Patent number: 4455915
    Abstract: A feed hopper for shell casings for use with a cartridge loading machine. The hopper is in the form of a container having curving interior surfaces, the surfaces extending to a feed aperture at the bottom of the hopper connected to a feed tube. Preferably the hopper is of hemispherical shape. The hopper has a transverse member positioned diametrically across it over the aperture to prevent a casing from being dropped into it so that it could fall into the feed tube with its open end down. The configuration of the hopper causes the casings to feed steadily with the rim down into the aperture and the feed tube.

  • Patent number: 4188855
    Abstract: This invention, relating to the art of resizing and decapping fired cartridge cases, comprises a novel method of and apparatus for automatically and safely resizing spent cartridge cases having primer caps, including means for automatically resizing the cases and clearing the case of the spent primer therein, in a highly efficient, automatic procedure, uniformly restoring cartridge cases for reuse. Pursuant to the invention means are provided which automatically orient the fired cases and feed them to a case receiving station from which they are sequentially advanced to a registration station, where swaging or sizing of the outside dimensions of the case to their original dimensions is effectuated and the case is decapped and reclaimed for reuse; the so resized and decapped case is displaced from the apparatus simultaneously automatically on positioning the next case at the registration station for repetition of the procedure.
