Abstract

506,323. Making scythes. VEREINIG UNG DER DEUTSCHEN SENSENWERKE E. V. Oct. 25, 1938, No. 30824. Convention date, Oct. 26, 1937. [Classes 83 (ii) and 83 (iv)] Bending-dies.-In a method of making scythes, a flat piece of steel is hot-shaped, as by rolling, so that when cut along a line as at 10, Fig. 8, two roughly shaped scythes are produced having thickened longitudinal back edges 3 and thickened transverse end portions constituting the shanks 4 and tongues 5, the scythes being given their final shape by bending. The bending is performed in two stages. In the first, the end or nose 12 of the scythe is curved in a swage of which the lower die 1 comprises a concave abutment 14 of channel shape in cross section and bounded on one side by a wall 15 extending obliquely and outwardly upwards. The corresponding upper member comprises a convex ram 16. In the. second operation the whole length of the blade is shaped in a similar but longer form of swage.
