Abstract
337,219. Rheinische Metallwaarenund Maschinenfabrik, and Witzell, K. Nov. 13, 1929. Ordnance tubes.-A liner for the chamber and rear end of the rifled bore of a gun has projections on the front face thereof which engage with recesses in the end of the non-removable part of the bore. In one construction, the adjoining surfaces d of a barrel b and its liner a, Figs. 1 and 2, are helical in shape and have stepped-down faces c arranged parallel to the axis of the bore. The helical surfaces d are of opposite hand to the rifling grooves in the barrel and liner, so that the tendency of the latter to rotate relatively to the barrel when a shot is fired serves to force the surfaces d more firmly into contact with each other. The stepped-down surfaces d are so disposed that the rifling grooves in the liner form an uninterrupted continuation of those in the barrel.
