| 359,608. Ordnance. SCHNEIDER ET CIE, 42, Rue d'Anjou, Paris. Aug. 8, 1930, No. 23785. Convention date, May 24. [Class 92 (ii).] Breech mechanism.-Relates to semi-automatic mechanism of the kind described in Specification 306,113, [Class 92 (ii), Ordnance &c.], in which during run-out the breech is automatically opened against the action of a closing spring by the engagement of a pin c<1> on the operating lever C with an abutment e<3> on a rail E, the pin riding on a surface el on the rail to hold the breech open until the pin is released by hand-operated means Q to permit the breech to close. According to the present invention, the pin is moved to effect the release instead of moving the rail as in the prior Specification. The invention is shown applied to breech mechanism having an eccentric breech block B, Fig. 2, rotated by a pinion K engaging as a nut with a threaded piston-rod I<1> connected by a link C2 with an arm c<3> fast with the pivoted operating lever C. The closing spring J is compressed by a loose piston I<2> on the rod I<1> against which bears a second piston I fast with the rod. The piston I<2> can be held by a pivoted stop z to hold the spring compressed when the breech is opened by hand. The pin c<1> on the operating lever is released by an arm L<1> rocked about a vertical axis by a rod M which is moved against the action of a spring N by an arm o<1> on the lever Q when this lever is moved to the right. For the purpose of firing by hand, the lever Q is moved to the left and operates through rods P, S and lever T to lower a slide U, a hole U<1> in which then registers with a rod V on the firing mechanism to permit of forward movement of the rod to fire the gun. The rod V is cocked against the action of a spring W by rotating the firing hammer X which is geared with the rod by teeth V<1>. The gun can be fired automatically by adjusting the part T' of the lever T into engagement with a rod y which is pressed forwards by the rod I<1> at the end of the closing movement of the breech. | ||||||

| 263,214. Dawson, Sir A. T., and Buckham, Sir G. T. Sept. 15, 1925. Ordnance breech mechanism. - Relates to power-operated screw-breech mechanism of the kind having a single ram for ejecting the rotation of the screw and the swinging of the carrier, a cam device being provided between the screw and the gun so that the opening movement of the carrier is initiated by the final unlocking rotation of the screw and vice versa. According to the invention, the cylinder E of the ram, Fig. 4, is rigidly attached longitudinally to the gun A immediately in front of the carrier hinge-pin C<1>, and the piston rod e<1> of the ram is connected by a swinging-link mechanism E<3> - - E<5>, to a crank pin D<1> on the transverse screw-operating shaft D. The invention is shown applied to breech mechanism as described in Specification 6739/12, and a ram as described in Specification 205,522 is shown connected by a slider E<2> to the universally-jointed links E<3> - - E<5>. The position of the parts after unlocking rotation of the breech screw is shown in Fig. 6, the link E<5> having passed behind a projection C<2> on the carrier C so that further operation of the ram will swing the carrier open. During the swinging movement of the carrier, the crank-shaft D is prevented from rotation by a catch G, Fig. 14, which is automatically moved behind a lug D |
