Abstract
575,178. Cotters ; dowels. SCHMUZIGER, O. Feb. 29, 1944, No. 3742. [Class 89 (ii)] [Also in Group XXII] Springy longitudinally split tubular pins, cotters, dowels, plugs &c. for insertion into holes for locking or uniting parts, are made from strip steel containing manganese and silicon, with more than one per cent. of one of the elements, preferably silicon, the strip being cut into blocks having a width equal to twice the outside diameter of the finished article and then cold pressed and at the same time rolled or bent in the direction of the grain over a mandrel to provide between the edges a gap ranging from D to 3D - 1 where D is the external diameter d+1 d+3 and d the internal diameter, the bent block being finally tempered. The width of the block may vary to an extent representing a machining allowance of 15 per cent. One end may be tapered during bending or subsequently ground to proper taper or rounded off and the other end trimmed. The strip may contain 0.6 per cent of carbon, 0.9 per cent of manganese, and 1.9 per cent of silicon.
