Improvements relating to small arms

摘要

The stock and butt 1, 2, Fig. 6, of a smallarm is made into a continuous body of fibrous material and binder hollow over the greater part of the length of both the stock and the butt. The fibrous material may be wood fibre, veneer sheets, paper, paper fabric, cotton fabric, staple fibre fabric, cellulose wool, or spun cellulose; and the binder may be artificial resin. The material is first made from a tubular piece or a flat piece into a hollow blank, and then the blank is pressed to the finished state with the application of heat. For example, a flat piece is first made of the shape shown in Fig. 2, and is then bent and moulded with heat treatment in successive moulds A, B, Figs. 3 and 5. Or sheets of the material are rolled one over the other with staggered joints into tubular forms as shown in Figs. 8a and 8b, and these are then moulded to shape. Solid insertions, such as 11, 16, 18, Fig. 6, 12, Fig. 6b, and 13, Fig. 6a, are provided where desirable; and the rear end of the stock is closed by an inserted plate 14.
