Abstract
651,860. Making crank-shafts. COM. PAGNIE DES FORGES ET ACIERIES DE LA MARINE ET D'HOMECOURT. Dec. 24, 1947, No. 34139. Convention date, Dec. 27, 1946. Drawings to Specification. [Classes 83 (ii) and 83 (iv)] Forging.-Hollow crank-shafts or the like are made from hollow blanks with a removable core by upsetting and bending in the apparatus described in. Specification 628,519. Fillings.-The blank may have one end solid or plugged, the other end being plugged after filling with sand, refractory earth &c. or a metal such as copper which has a melting point below the forging temperature of the workpiece but not sufficiently high to affect the properties of the workpiece when the filler is melted out. Specification 622,938 also is referred to.
