23,840. Wang, E. G. Nov. 6. Preventing erosion - A special gas check is so arranged on the projectile that it is brought into action during the ramming-operation, thus making the projectile gas-tight in the bore of the gun before firing. The gas check consists of a soft-metal ring a separate from, or combined with, the driving- band b, as shown in Figs. 1, 3, and 5, the range a being so arranged that, in each case, it grips the bore of the gun before the driving-band b. Fig. 7 shows a modification in which the ring a moves towards the band b during the ramming-operation, thereby compressing asbestos packing c.
