Abstract

979,611. Making tinsnips; welding by pressure. WARD & PAYNE Ltd. Nov. 2, 1963, No. 43328/63. Addition to 964,629. Headings B3A and B3R. A method of making each half of a pair of tinsnips or like tool comprises welding, e.g. by electrical butt-welding, end to end a length of tough tool steel and a length of high-speed steel and forging the resultant composite length to form a blade, shank and lever handle, of which the shank and handle are of tough tool steel and the blade of high-speed steel. The high-speed steel contains from 14 to 22% tungsten, preferably 18%, and the lengths are preferably of round bar. The welding flash is removed and the composite length preferably machined all over prior to shaping by drop forging. After forging, the part is finally machined and ground and the shank bored to receive a pivot. The shank and lever handle are preferably hardened.
