Title: Improved safety apparatus for preventing the opening of the breech of a gun before the recoil of the gun barrel
IPC: F41A17/18
Filed: 1920-12-13
Abstract: 157,073. Schneider et Cie. Jan. 14, 1920, [Convention date]. Ordnance breech mechanism.-Relates to a hang-fire safety device of the kind which co - operates with a breech-operating lever E, the handle G of which is moved along its axis to release a catch g<2>, H prior to swinging the lever to open the breech. The invention consists in providing a safety catch I which is movable round a spring bolt J and prevents the axial movement of the handle G until after the gun has recoiled. Fig. 2 shows the parts in the firing position.. The catch I is rockingly mounted on its bolt J which is arranged between spring boxes K carried by the gun. Acting on the right-hand side of the bolt J is a spring J' which is stronger than the spring I<2> on the left, the latter also acting as a torsion spring tending to rotate the catch I in clockwise direction as seen from the left of Fig. 2. In the position shown, the spring J<1> is compressed by the engagement of the bolt J with a ramp M on the gun cradle, and the catch I therefore lies in the path of the extension G<2> of the handle G. When the lever E is moving to the closing position, as shown in Fig. 4, the projection g<2> on the handle G rides beneath the surface H on the carrier, and as it rises to engage the abutment h<2>, the catch I slips behind a shoulder g<3> to lock the handle against downward movement. When the gun recoils, the bolt J leaves the ramp M and is, together with the catch I, moved to the left, Fig. 2, to release the handle. At the end of the run out, the bolt J is pressed inwards by the ramp and leaves the catch I in the position shown in Fig. 8 until the opening of the breech permits it to return to the position shown in Fig. 4. By means of a hand-lever P<1> carrying a cam P, the catch I can be rocked if desired out of the path of the handle G.
