Abstract

The automatic hand firearm has a body (1) with a handle (2) joined to it and a sliding plug (4) with a guide (5) in the body and a return spring (6). The guide for the sliding plug ascends rearwardly, so that the rearward path of motion of the plug deviates upward from the centre line of the barrel. When the sliding plug is in its forward position, its centre of gravity is in front of the handle. - The guide forms an obliquely forward sloping and downwardly inclined surface on which the sliding plug rests, so that when the recoil force acts on the plug it moves rearward and its lower surface engages the surface of the guide to lower the muzzle. (1/4) EPAB- EP-105272 B An automatic, mass-obturated head firearm comprising a body (1) including a handle (2), a barrel (3) connected to the body, a breech block (4) including a return spring (6), a guide (5) constituted by the body and for guiding the breech block in sliding movement and a cocking and firing mechanism (7), the guide including an inclined guiding surface that extends upwardly and rearwardly with respect to the axis of the barrel, characterised in that when the breech block (4) is in its forward position its centre of gravity (9) is located forward of the handle (2). (6pp) USAB- US4569270 A The automatic, mass-obturated hand firearm a body (1) with a handle (2), a barrel (3) joined to the body and a breech block (4) with a guide (5) constituted by the body. The guide of the breech block ascends rearward so that the rearward path of motion of the breech block deviates upward from the centerline (8) of the barrel. - When the breech block is in its position, its centre of gravity (9) is located forward of the handle. The breech block is pref. disposed to have its major part forward of the rear end (10) of the barrel. The guide of the breech block forms a pref. obliquely forward and downward inclined surface, against which the breech block rests.
