Title: Improvements in or relating to sporting guns
IPC: F41A3/18
Filed: 1948-04-01
Abstract: 649,450. Sporting guns. CHEVALLIER, A. L., and SOCHACZEWSKI, S. April 1, 1948, No. 9217. [Class 119] A single-barrelled sporting gun adapted to fire two cartridges in rapid succession comprises a barrel 1, a breech frame 2, a rotary breech bolt 13, Fig. 9, slidably mounted in a raceway 5, a transverse slot through the frame forming a side loading aperture 11, Fig. 3, and an ejection aperture 10 on the other side, a floating inertiacontrolled member 37, Fig. 1, loosely coupled with the breech bolt and slidable longitudinally on the breech frame, manually-operated means 23 engaging the underside of the breech bolt for unlocking and opening the breech and an automatic quick-loading attachment 48, Fig. 13, or Fig. 17, for the second cartridge 49 mounted over said loading aperture 11. In the form shown, the rotary breech bolt 13 (not shown in Fig. 1) has a fixed head 14, Fig. 9, with a guide wing 15, Fig. 10, moving in a longitudinal groove 16 in the frame and a projection 17 moving in a groove 18. The breech bolt is locked after a quarter turn by a rib 19 engaging a recess 20 in the frame. Locking and unlocking of the bolt is effected by a sliding fore end through a drive rod 23 and a tooth 28 engaging the bolt 13 and head 14 in the locked position. On rearward movement of the drive rod, the tooth 28 engages a cam groove 31 in the bolt to unlock and drive the bolt to the rear in race 5, cock the hammer 32 and extract and eject the cartridge case. The drive rod is locked in forward position by a pivoted spring-urged plate 33 released by the shock of discharge or by button 36. The inertia hood 37 absorbs recoil and locks the bolt against opening in case of hang fire. The hood is urged rearwards by V springs and moves forward on discharge for a peg 46 to engage the breech bolt and reshape the cartridge case to facilitate extraction. After unlocking rotation of bolt, peg 46 can engage groove 47, Fig. 10, in the bolt during the opening movement. The loader 48, Fig. 13, for the second cartridge 49 has a hinged spring-pressed lid 50 and is secured over the opening 11 by rabbets 54 and slideway 55. The cartridge 49 is pressed by a spring pin 60 on closing the lid against the first cartridge so that automatic loading of the second cartridge occurs after the breech opens and the first case is extracted and ejected. The firing pin 65, Fig. 9, has a rear cam face 67 to cause retraction during unlocking rotation of the bolt and firing can only take place when the bolt is locked. The inertia hood is made of steel and is heavy in relation to the other gun parts made of aluminium alloy. In the alternative loader, Fig. 17, the cartridge 49 bearing against a part 146 of the hinge under the pressure of a spring 145 keeps the loader closed until the first case is extracted when the lid springs open and the part 146 flicks the second cartridge into loading position.

Abstract: 445,977. Automatic volume control. SIEMENS & HALSKE AKT.-GES., Siemensstadt, Berlin. March 25, 1935, No. 9273. Convention date, March 23, 1934. [Class 40 (iv)] [See also Group XL] A volume-regulating resistance network comprises an element having a negative temperature coefficient and consisting of a filament of uranium dioxide in vacuo to which a control voltage is applied. Fig. 1 shows the application of the invention to an automatic volume controlling system in which a control frequency is filtered from the output of an amplifier V, rectified and made to control the current through and therefore the value of the resistance of the filament R- which forms an element in a potential divider. Fig. 2 shows a filament of uranium dioxide as a shunt element in a four-terminal network. Several such networks may be employed in tandem. The Specification as open to inspection under Sect. 91 comprises also arrangements in which a variable element such as an incandescent lamp having a positive temperature coefficient is employed. In one of these, Fig. 2 (Cancelled), an increase in signal strength causes a reduction in the current through the variable element. The others are similar to the arrangements shown in Figs. 1 and 2, except that the fixed and variable elements are transposed as regards the main transmission path. These systems are not included in the Specification as accepted.
