Abstract: A cartridge in a weapon capable of firing several different calibers is provided. The cartridge bore is adapted for use in weapons having extractor and positioner mechanisms which permit use of different caliber casings in the same weapon. With the cartridge bore according to the present invention, casings are more easily removed after firing and are less likely to stick.

Abstract: An extractor and positioner mechanism is provided for revolvers or like weapons. An increased area contact surface is provided for enhancing the positioning and extraction or ejection functions. The mechanism also allows proper seating in the chamber for rimmed and rimless cartridges. Loading of cartridges into chambers in the revolvers is also made easier.

Abstract: An ejecting mechanism for revolvers having a cylinder with a movable axle longitudinally mounted on the longitudinal axis of the cylinder. The axle has outwardly and upwardly inclined casing contacting arms formed of light spring material. A ratchet plate is detachably mounted on the end of the axle for revolving the cylinder of the gun.

Abstract: A device for loading revolvers from the front of the cylinder, a rotating cylinder in the revolver designed to releasably retain cartridges therein and to receive new loads from the loader and at the same time eject the empty casings. The rotating cylinder has a pivotal yoke and an arm extending laterally therefrom with a locking means for releasably maintaining the revolver cylinder in firing position on the frame. Guides are provided for aligning the cartridge chambers of the respective cylinders with each other. A loading cylinder abuts the revolver cylinder for reloading. A series of rams are provided which are movable against the reloading cartridges and which will contact the spent casings in the revolver cylinder and eject same. Casing retainers in the revolver cylinder will secure the reloads in place therein. A back plate mounted on the rear end face of the revolver cylinder maintains the holding means in the chambers in holding position.
