Semi-automatic weapon

Abstract

The inventive smallarms embodiments are characterised in that both the cocking mechanism and the mechanism for feeding ammunition with the inventive cartridge chamber-magazine operate similar to the principle of operating a typewriter carriage. Said cocking mechanism comprises a movable member ( 13 ) which may move within a casing ( 2 ) and is used for cocking a hammer ( 17 ) with the aid of an arming spring ( 9 ), thus that the shape and dimensions of the movable element ( 13 ), the rigidity of said spring ( 9 ) and the travel thereof ensure several cycles of cockings of the hammer ( 17 ) during one working movement of the compressed spring ( 9 ), and the movable member ( 13 ) may be stopped after every cycle of cocking the hammer ( 17 ). The inventive movable cartridge chamber-magazine ( 3 ) for a lateral feed has through receiving holes for cartridges ( 31, 45 ) which are disposed in rows, and said chamber-magazine is arranged between the back part of a barrel ( 43, 44 ) and the casing ( 2 ) and embodied with possibility to stop when the axis of the cartridge ( 31, 45 ) coincides with the axis of the barrel ( 43, 44 ). The inventive weapon system makes it possible in relatively simple manner to use different barrels (with respect to the calibre, rifling thereof etc.) and to feed the ammunition manually or semi-automatically and to select required cartridge calibre or the type thereof for shooting.
